The next morning, Xu Shu saw giant shield soldiers standing under the city wall standing under Shouchun City, row by row, very elite and neat, with giant shields heavy armor? A sneer appeared on the corner of Xu Shu's mouth, thinking that using this formation could withstand the bed crossbow?

The bed crossbow in Xu Shu's hand is an improved version. His previous seniors could directly penetrate the wooden boards of the warship. The wooden boards were extremely thick, and some could be more than several feet long. They were cut from those giant trees. There was iron flask on those wooden boards, which were extremely strong, but even this was also a piercing member. These giant shields and heavy armors may be hard bones in front of the arrows in front of the swords, but in front of the giant arrows of the bed crossbow, there were a bunch of local chickens and tiles, which were vulnerable at all.

"Put the bowstring!" Without Xu Shu's words, Deng Yi next to him pushed out the twelve crossbows and stood on the top of the city.

"Military advisor, is this really okay??" Liu Bei asked Feng Chu next to him. It's not that Liu Bei was worried. These giant shield soldiers and heavy armored soldiers were all white-eared and heavy armored. Liu Bei didn't want to lose any of them. Before, Chen Dao wanted to ask for his order to fill the moat, but was stopped by Liu Bei, but now he has to take it out.

"Don't worry, lord, there is a powerful weapon in the camp. It will be a matter of time before Shouchun City is destroyed," Pang Tong felt a little confident.

"But!" Liu Bei was still very confused. His eyes floated against Zhang Xiu from time to time. It means that Zhang Xiu set an example and told everyone that the giant crossbow arrows on the city wall could not resist any impact with the arrow. The heavy armor that could make everyone feel at ease became like paper. A giant arrow shot out from the city wall, which could penetrate seven or eight layers of heavy armor, and the cavalry and war horses penetrated through such lethality. Can the giant shields and heavy armor resist it!

"Did your lord forget that the second general's Battle of Shouchun?!" In order to reassure Liu Bei, Pang Tong had to pull Guan Yu in. Guan Yu's Battle of Shouchun? It was no longer a war. Instead, it was a escape. Liu Mang went down to Shouchun City in one day, and Guan Yu in the city had no ability to counterattack, so he abandoned the city and fled. In the end, he left a lot of military rations and weapons in the city, which was a pain in Guan Yu's heart.

"The Battle of Shouchun in Second Brother?!" Guan Yu's pain did not make Liu Bei sad with him. On the contrary, Liu Bei's eyes lit up now. One day he went down to Shouchun. In addition to being the siege of Liu Mang's army, there was another stone throwing machine. This made Guan Yu lose Shouchun, because even if he persisted, he could only add casualties in vain. But now the role has changed. The siege became Liu Bei, and the defender became Liu Mang's army. "A weapon in the camp, can he really compete with the pseudo-king's stone throwing machine?!"

"This?!" The information Pang Tong got from the young man was not possible! Because from Guan Yu's description, Liu Mang's stone thrower could throw more than 300 kilograms of heavy stones to 300 to 500 steps. If he installed more than 100 kilograms of heavy stones, he could hit a distance of 700 steps. In this era when there was basically no leverage principle, no lathe or spring, all stone throwers were made of wood, so young man naturally felt inferior, but young man was not so confident about his own stone thrower. If he fought against Liu Mang's crossbow, he might not be his opponent. After all, Liu Mang's one had already used some spring devices. But bombarding the city wall was still more than enough.

Of course, Pang Tong would not say that he was not as good as Liu Mang's crossbow to attack Liu Bei's self-confidence, but said indifferently, "It's even better!"

This sentence finally made Liu Bei feel relieved, and then he immediately ordered Chen Dao to act according to his plan.

"I will obey the order!" Chen Dao said with a fist, then went down to prepare for the matter.

"Lord, what do you think Liu Bei wants to do?!" Next to Liu Bei's camp is Zhang Xiu's camp, and Zhang Xiu is also paying attention to the battle in Shouchun. Yesterday, the losses of his Western Liang Iron Cavalry made Zhang Xiu miserable. More than a thousand casualties were added in vain and there was no place to cry. Who told him to run over and slap Xu Shu on Shouchun in the face with a crossbow?

"Liu Bei?!" Zhang Xiu was also very confused. What was Liu Bei thinking? Can you not be afraid of the crossbow on the city wall with a giant shield and heavy armor? Zhang Xiu was a general and naturally knew the ability of this crossbow to penetrate. He could nail a heavy armored cavalry to the earth with a man and a war horse, steadily and firmly. Even if the crossbow aimed at him, Zhang Xiu had no certainty to block it. But now Liu Bei actually used the white-eared heavy armor to test it, which made Zhang Xiu confused. However, looking at Chen Dao, who was training the white-eared heavy armor, Zhang Xi actually believed that Liu Bei's army might really have a way.

"Everyone, take the sandbag!" Chen Dao shouted. Except for the white-eared heavy armored soldiers in the front row, who were holding giant shields, the other soldiers carried generations of sandbags, carrying him on their shoulders, waiting for Chen Dao's orders.

"Okay, the target Shouchun moat is moving forward!" Chen Dao roared in a low voice. The white-eared heavy armored soldiers were his pride. Although this white-eared heavy armored soldiers could only be established with the help of Guan Yu, Zhang Fei and Liu Bei, most of them were still under the leadership of Chen Dao, which was his hard work.

In Chen Dao's opinion, the one who can truly compete with Bai'er and Heavy Armor in this world is the Bingzhou Wolf Cavalry, the world's number one cavalry. Even the Black Chess Camp, which also belongs to the heavy armor cavalry, and the famous army under the King of Shu were not taken seriously by Chen Dao. Now the Bingzhou Wolf Cavalry has been crippled, and it is basically impossible for half a year to appear again, so it is basically invincible in the Central Plains.

"Boom, boom, boom!" Unlike the kind of charge tremor brought by heavy armored cavalry, the white-eared heavy armor brought neat planning steps, and the military orders were consistent and the orders were carried out. It was not only a dogma of Liu Mang for the urban management army, but also a method of governing the army with white-eared heavy armor. Even if the abyss and hell in front of you, you have to charge forward under the orders. This is why Cao Cao could not keep Liu Bei despite sending tiger and leopard cavalry several times.

"Giant shield and heavy armor? Haha, today I will make you a candied haws!" Xu Shu looked at the white-eared heavy armored soldiers who were getting closer and closer. Finally, after the white-eared heavy armored soldiers approached the range of the bed crossbow, the twelve bed crossbows roared again.

"Swoosh swish swish!" One giant crossbow arrow after another was shot out. Under the huge elastic force of the bowstring, each giant arrow felt like it was tearing open the air, making a sound of air vibration.

"Boom!" The first row of white-eared heavy armored giant shield finally contacted the giant arrows of the bed crossbow. Like the previous Western Liang cavalry, there was no second choice. Even with the help of this giant shield, the power of the bed crossbow was still revealed. The giant shield was directly smashed, and the bed crossbow also pierced the white-eared heavy armored soldiers hiding behind the giant shield without any effort. The white-eared heavy armored soldiers were infantry wearing two layers of heavy armor. In addition to the outer layer of heavy armor, there was also a layer of chain armor on the underwear that was inner armor. This inner armor may not have high defense power for ordinary swords, but it has a good resistance to weapons such as bows and arrows. The arrows of the crossbows cannot penetrate the inner armor at all, but now it is like a joke. The inner armor is fully penetrated, and most of the white-eared heavy armored soldiers in the first row are killed and injured.

"Continue. Don't stop shooting!" Xu Shu stood on the top of the city and gave an order to the crossbow. This was a Bai'er Heavy Armored Soldier. Xu Shu also saw that, otherwise there would not be such neat steps. Bai'er Heavy Armored Soldiers were the elite among Liu Bei's elite. If he could abolish him under Shouchun City, then Xu Shu's army would have made a lot of money.

Although there were only twelve bed crossbows, the arrow rain he formed was not bad at all. After all, his body was huge and the bed crossbows could be shot continuously. The white-eared heavy armored soldiers under the city were worthy of being elite. After the first row of giant shields were pierced through the heavy armor, the second row quickly took over the first row. The surviving soldiers who could be treated were naturally treated. Those who could not be treated gave up directly.

"No matter how many shields are, can I have more giant arrows?!" Another row of arrow rains were densely falling. According to the truth, Liu Bei's army should be very distressed when the white-eared heavy armor lost such a loss, but Chen Dao's eyes were flashing, looking at the Liu Bei's army camp behind the military formation.

In addition to Pang Tong, there was another young man in Liu Bei's army camp standing on the platform and watching the scene in front of him. "Two hundred steps, shot through the first and second layers of giant shields, and the heavy armor was useless at all!" As he said that, he also recorded "Okay, military advisor!"

"Yes!" Pang Tong nodded and waved the flag in his hand. Chen Dao, among the white-eared heavy armored infantry, breathed a sigh of relief when he saw this flag. To be honest, Chen Dao couldn't bear the shooting of such a crossbow. Seeing the flag, Chen Dao immediately shouted, "Retreat, one hundred steps!"

After one after another, another pair of giant shield soldiers stood in front of him, and the entire white-eared heavy armored army began to retreat.

"Want to run? Leave half of it for me!" Xu Shu said coldly. Yesterday, the Western Liang Iron Cavalry dispersed halfway through the charge. The originally concentrated team suddenly dispersed, causing the hit rate of the crossbow to be greatly reduced. Moreover, because the speed of the war horses was fast, the Western Liang Iron Cavalry quickly ran out of the range of the crossbow, making the crossbow sigh. But today is different. Today is the white-eared heavy armored soldiers of Liu Bei's army. He is an infantryman, so his speed is not too fast. Waves of arrow rain shot over again.

"Every ten arrows, one cycle?" The young man recorded again. The crossbow on the city was shot very quickly, but every ten shots, he would pause for a moment. Although the pause didn't last long, the young man still noticed it.

"General, it's one hundred steps!" said the white-eared heavily armored soldiers to Chen Dao. Chen Dao nodded, and the army slowed down again.

"Swoosh swish swish!" There was no difference between 300 steps in front of the crossbow, and 200 steps, but the giant shield was torn apart and penetrated the heavy armored infantry behind.

"Three hundred steps, is it still a huge shield penetrated?!" The young man began to frown. He really didn't expect that such a person in this world would design such a sharp weapon. Three hundred steps may arrive instantly for the cavalry, but for the infantry, they have to run for a while. If there is such a sharp weapon on each city wall to defend the city, it will become difficult to attack the city in the future. "Continue, military advisor!" Pang Tong's flag waved again.

Chen Dao's white-eared heavy armor retreated a hundred steps again. This time it was much better, but the giant shield was still penetrated, but only two or three soldiers behind the crossbow were shot.

"The military advisor's white-eared heavy armor runs very slowly. Is this fool the commander? The arrows are the living targets. At this time, the retreat is still going to speed up the running? He is still carrying those giant shields!" Deng Yi looked at the white-eared heavy armored soldiers who left a corpse under the city and said disdainfully. If he was the one who commanded this team, he would definitely let his subordinates throw away the giant shield in his hand, so that they could run fast and let their subordinates scatter. Once they gathered together, they would be innocent to provoke the shooting of the crossbow.

"No, no!" Xu Shu was finally reminded by Deng Yi. Is the commander of the Bai-Earth Heavy Armored Infantry a fool? If he was a fool, would Liu Bei ask him to come out to command? Using the Heavy Armored Infantry to fill the moat was not a good deal. The Heavy Armored Infantry runs slowly, and the sandbag he carried was amazingly heavy, but how many trips could he run back and forth like this? Xu Shu was a little uneasy, so he quickly picked up the telescope that Liu Mang gave him and looked around, not only looking at the Bai-Earth Heavy Armored Infantry, but also Liu Bei's camp behind him.

"What's wrong with the military advisors? Didn't they come to fill the moat? I thought I was going to take a giant shield and I was going to be a turtle shell. Unfortunately, everything was useless in front of our crossbow!" Deng Yi said proudly.

"It's not about filling the moat!" Xu Shu shook his head. Although the soldiers were holding sandbags in their hands, they were not close to the moat at all. Moreover, many people's sandbags were thrown away. The sandbags were simply confusing him and others.

"That's it?!" Xu Shu finally saw a sign flag. He was being held in his hand by his close friend Feng Chu Pang Tong. Every time the sign flag was waved, the white-eared heavy armored soldier took a step back.

"Not good!" Xu Shu finally knew where this wrong feeling was, but it was too late.

Five hundred steps! Six hundred steps, until seven hundred steps, the power of the bed crossbow finally became smaller. Although the bed crossbow can still destroy the giant shield, it can only shoot through the giant shield, but it cannot penetrate it and is stuck on the giant shield.

"Stop at seven hundred steps?" The young man in Liu Bei's army camp finally finished recording. He smiled and said to Pang Tong next to him, "Military advisor, we can fight back!"

"Counterattack!" Pang Tong laughed, but he was just waiting for the young man's words. "Comeone came, and we were passed on our military order. We have been beaten for so long, so we should take out our weapon and show it!"

"Yes!" The soldiers next to him were about to take the order. The flag in Pang Tong's hand was not idle and continued to wave it. Now it was no longer an order to let Bai Er Chongjia advance or retreat, but an order to withdraw his troops and return to the camp.

Seeing the meaning of this order flag, Chen Dao finally breathed a sigh of relief. He had been very distressed just now. He fully realized the sadness and anger of Hu Cheer before. He was attacked without any strength to fight back, and the casualties were very heavy. With just 700 steps, Chen Dao left more than 700 corpses. Those were all white-eared heavy armored soldiers. Every time Chen Dao died, he felt sorry for every death. He had only been less than 500 casualties when he was ambushing the Bingzhou Wolf Cavalry, but now he lost 700 people. How can he feel good? Fortunately, the "The whole army returns to the camp!" Chen Dao's order also made these white-eared heavy armored soldiers let go of their courage and walk through the rain of arrows on the crossbow. That is really not something ordinary people can do, because you don't know if you are the person who died next time.

"Lord, look, Liu Bei and Liu Da'er's army were also beaten away and were about to return to the camp!" Hu Che'er looked a little gloating. After all, when his Xiliang cavalry suffered so many casualties yesterday, the generals of Liu Bei's army did not give him Hu Che'er a good look.

"Isn't you beaten away?" Zhang Xiu is a general and a lord. He naturally thinks much more than Hu Cheer's war. Is Liu Bei so likely to pull out the white-eared heavy armor to die in vain? There must be something wrong with it.

After a while, Zhang Xiu's doubts were resolved, because the sound of pulling silk suddenly came from Liu Bei's military camp. The sound of hey, the sound of hey was very loud. Zhang Xiu looked closely and realized that nearly ten large wooden racks were pulled out of Liu Bei's camp.

"What is this lord?" Hu Cheer from Xiliang, is from Qiang people. He is not very familiar with the war in the Central Plains, and does not know much about this wooden frame.

"Take the stone!" Zhang Xiu spit out these three words. The ancients started from primitive society. Because they had to be guarded against the attack of wild beasts, they designed a city wall to protect the city wall to prevent the attack of wild beasts. At that time, the city wall was made of fences and wood, and few wild beasts could climb the walls. After that, humans gradually became the protagonists of the world and became the pinnacle of the food chain. There were fewer threats from wild beasts, but the threats from people themselves became larger, so the city wall gradually became made of stone blue bricks, and the city wall became larger and higher, and it was impossible to cross the city wall just by climbing. The side with the city wall has a natural defensive advantage.

However, the struggle between humans cannot stop because of the height of the city wall. Since the city wall was created, there are naturally attack-type buildings to break through the city wall. The thing in front of him is a powerful tool to break through the city wall. He and the chassis and the well railing are called three powerful tools. There are many people who can make chassis, and many people can use it. However, this thing can be made, because it involves the science of the mechanism. Since Emperor Wu of Han, Dong Zhongshu has abolished all schools of thought and respected Confucianism. There are very few people who have real science of the mechanism, so not only are the well railings rarely appear, but the catapult is even more rare.

Normally, when siege, the car is rushing in front of the ladder, and the ladder is piled up with human lives to fight against the enemy to see who has more people and who can't bear it first. With this thing, many people can be killed less.

"Catting machine?" Hu Cheer looked at the wooden shelves with a puzzled look. The Han people's things were magical. Although the giant arrow shot from the crossbow before made Hu Cheer very uncomfortable with countless men under his command, it also made Hu Cheer understand that those crossbows were treasures.

"Cater?!" The same sentiment was Xu Shu on the Shouchun city wall. Xu Shu never expected that the Liu Bei army could take out the trench machine! "Is the industrial zone not burned? Let Liu Bei get the drawings?!" Xu Shu didn't dare to think so. If the crossbow drawings of Liu Mang's army fell into Liu Bei's hands, then Shouchun would be really difficult to defend. With the attack power of the crossbow, what kind of city wall can withstand such a blow?

"Absolutely no military advisor!" Deng Yi stood aside and explained, "The drawings of the crossbow cannons are no longer in the industrial zone, and the craftsmen who can make crossbows have long been moved into the city by the last general!" Liu Mang practiced the talent in Shouchun, and such talents include these craftsmen who can learn from the government! Although they didn't know anything about it, they had their own skills. Liu Mang's many things were not just created by Liu Ye. There were also these craftsmen who were inspired by Liu Mang, so the status of craftsmen in Liu Mang's army is no worse than that of officials. A master of craftsmen, Liu Mang, paid a salary of 500 stones, so these craftsmen were the first person Deng Yi wanted to protect.

"How could that happen?!" Xu Shu looked carefully again, and then he found that the catapults were different from many places developed in Liu Mang's army. Liu Mang's crossbow was formed by a very long lever, but the catapult in front of him was made of a huge roller. Xu Shu didn't know how powerful he was, but he knew that since Liu Bei's army had taken out such a thing, he would definitely not be aimless. "There are experts in Liu Bei's army!"

"Deng Yi immediately ordered it to go down. Let some wet cowhide and bedding come up under the city, hurry up!" Xu Shu hurriedly ordered it. No matter what the catapult on the opposite side looked like, Xu Shu needed to be on guard against him.

"The last general will take the order!" Deng Yi quickly went down. After a while, he got up. He couldn't find many wet cowhide quilts in such a short time. He could only take out dozens of cowhide and some quilts. "Hurry, spread all the wet cowhides on the city wall. Wrap the city heads for me!" The huge rocks shot out by the catapult fell on the city heads, and brought damage with huge impact. Xu Shu's method was to wrap the city heads with soft things, so that the huge rocks had a buffering force when they fell and reduced damage.

"Haha, do you use wet cowhide and bedding?!" The young man on the high platform of Liu Bei's army camp looked at the preparations on the Shouchun city wall and laughed. "If this thing is an ordinary trencher, it really has many functions. Unfortunately, what you encountered was my Ma Jun's rotary trencher!"

Soon Xu Shu felt the feeling of being bombarded by a stone thrower.

"Report to the lord, everything is ready!" The ten Ma Jun's rotating stone thrower were ready at once, and the huge stones were placed on the round wheels on the stone thrower.

"Okay, I'll send my military orders to blow off all the crossbows on the city wall!" Liu Bei was finally going to extricate his anger. He was suppressed by the crossbows on the city wall. Now he finally had to fight back, so he didn't feel uncomfortable.

"Yes!" The school took the order and left. The cross stone throwers began to operate. A very long rocking handle was on the huge disc. Ten soldiers were rotating the huge rocking handle with force. The rocking handle was driven onto the disc, allowing the huge rocks in the disc to run at a high speed. At a certain speed, they directly shot out the huge rocks in the circular wheel.

"Boom boom boom!" The first big rock rain fell down, and the first one was the head of the city wall. Xu Shu's wet cowhide and bedding played a role. Under the buffering force, the damage caused by the big rock to the city wall was reduced a lot. Moreover, because it was the first round of shooting, both the angle and the hit were much lower, which made the soldiers on the city breathe a sigh of relief.

"Hmm? That's the power?!" Liu Bei was disappointed. He thought that this stone thrower could bring him some major victory, so he didn't expect him to blow up Shouchun directly. At least he had to destroy the crossbows, but now the first round of shooting only brought such a small result. Only one or two unlucky soldiers on the entire city wall were hit by a huge rock.

"My lord, don't be impatient!" Pang Tongxin was also sweating coldly. If this stone thrower had no effect, it would really depend on the people to accumulate.

"Wet cowhide, the bedding can block it! It's so whimsical!" The young man was very confident and shouted loudly, "Accelerate, accelerate! Upward angle, eject!" Under the guidance of the young man, the stone throwers adjusted the angle and raised the shooting point. There were not only people pulling the shaking handles beside the stone throwers, but also people holding the stones and quickly putting the stones into the round wheel. After high-speed operation, one huge rock after another was shot out.

"Boom boom boom boom!" This time, it was not as free as the last time. The stones ejected this time were one after another. Although wet cowhide and bedding could form a buffer to offset the damage, it could not offset it all the time. The walls on the city walls were bombarded for a long time and could not bear it.

"What?!" Xu Shu really didn't expect that the catapult outside could shoot like a crossbow. Even Liu Mang's catapult could not do this level! Liu Mang's crossbow cannon could not shoot continuously because he focused on the quality, strength and power of the shells. Each huge rock had three hundred kilograms, while Ma Jun's catapult pursued the rate of fire. It was continuous shooting, and it did not stop the people on the city wall at all.

The wet cowhide and bedding were no longer able to resist it. The huge rock fell down and hit the city wall. The soldiers who were directly hit had no way to survive. Those who were not directly hit also cracked because of the falling huge rocks. Those tiny stones flew out and were pierced through the body, while those who were severe died on the spot.

The original stone-firing cart was like a large balance, with a bucket hanging on one end. The bucket was filled with stones of all sizes and many ropes hanging on the other end. During the battle, the soldiers pulled the ropes together and raised them up quickly. In this way, the stones were thrown out to attack the enemy. This kind of stone-firing cart has many disadvantages. Every time it was launched, it took some time and the effect was not great. The new rotating stone-firing cart designed by Ma Jun overcomes these shortcomings. It uses a wooden wheel to hang the stone on the wooden wheel. In this way, the machine is installed to drive the wheels to rotate quickly, and the large stones can be continuously launched, making the enemy unable to defend. Ma Jun once used the wheels for experiments, and could shoot dozens of bricks and tiles out hundreds of steps in a row. At that time, the power was quite great.

"Blast, fight back! Use the crossbow to shoot them back!" Deng Yi shouted loudly, and the soldiers who operated the crossbow quickly turned the shooting direction of the crossbow and shot directly towards the catapults.

"Haha! Are you using a bed crossbow?! What a pity!" The young man felt a little satisfied. The stone thrower he created himself could actually suppress the bed crossbow weapon made by the King of Shu. How could this not make the young man happy?

"General, our crossbow can't hurt them at all!" A general exclaimed, because the arrows shot out by their crossbow were basically blocked, and there were teams of giant shield soldiers beside the stone thrower. The crossbow can only harass them, but cannot hurt them.

"What!" Deng Yi was stunned, only Xu Shu was smiling bitterly. As expected, he was testing just now!

Seven hundred steps, this is the safe distance that Pang Tong and Ma Jun used the lives of nearly 700 white-eared heavy armored soldiers to test. Previously, the white-eared heavy armored soldiers were like being killed under Pang Tong's flag to test how far the bed crossbow could shoot, how many meters it could be protected from his damage, or to minimize his damage. It is obvious that five hundred steps to seven hundred steps is a very good distance.

"Boom boom boom boom!" The accuracy of Liu Bei's army's stone throwing machine under the city was getting higher and higher. Under the saturated blow, stones were thrown into the city wall one by one. "Ah ah ah ah ah!" There were endless screams of screams.

"No, the crossbow!" Deng Yi shouted, "Push the crossbow quickly and push it in!" Deng Yi was going to let these soldiers push the crossbow into the city tower, and he even helped the soldiers of a crossbow next to push the crossbow together. But everything seemed too late.

"General, be careful!" The guard next to him pushed Deng Yi suddenly, and Deng Yi was about to curse, but he was stunned before he could speak, because the place where he was standing had turned into a big pit, and a stone weighing hundreds of pounds was falling there steadily. The crossbow and the guard who pushed him away were all scattered all over the ground. The crossbow was scattered, and the guard was smashed into pieces, and the blood was all on Deng Yi's face.

After desperate efforts, two of the twelve crossbows dragged into the city tower, and the other ten were all reimbursed.
Chapter completed!
