Liu Mang saw that Liu Ye had knelt down and pleaded with Liu Mang for such a young man, which made Liu Mang a little magical. You must know that Liu Ye was still in charge of government affairs in Yangzhou before, and even Liu Ye went on a war with Liu Mang. It can be said that there are very few people in the world who can be the opponent of Liu Ye.

Originally, Liu Ye had the idea of ​​competing with Xu Shu, but after Liu Mang gave him those books, Liu Ye completely abandoned the idea of ​​developing in military and political affairs, and instead devoted himself to these books. So Liu Ye didn't give much face to him. Unexpectedly, Liu Ye knelt in front of him for the sake of this young scholar, and was still a stuttering person.

What is this person's ability? Liu Mang knew that Liu Ye came alone when he defected to him, and had no relatives, so there was no relationship or anything else.

Then there is only one possibility, that is, this person is very talented, and Liu Ye would plead for this person.

"Get up and talk!" Liu Mang waved his hand. Half of the industrial area was blown up. It was miserable here. Liu Mang could only shake his head and ask his subordinates to find a place where they could sit. Liu Ye and others followed Liu Mang to leave.

After finding a place to speak, Liu Mang took the lead and took several seats beside him. Liu Mang waved his hand and let everyone sit down.

"Is this young man Ziyang the right assistant minister of the Ministry of Works?" A minister of the Ministry of Works, two ministers, which is equivalent to one in charge and two deputy officers. The ancients regarded the left as the emperor, and there were other candidates for the left assistant minister of the Ministry of Works. This person was a man named Ge Luo. Although this person was not very talented, this person focused on his wealth. The Ministry of Works needed to collect more things. If a person who was not honest and liked to be greedy, Liu Mang would not be relieved.

Liu Ye was mainly responsible for turning the things in the books into reality, so he taught the basic affairs of the Ministry of Works to Ge Luo, and there was also the right assistant minister of the Ministry of Works, the young scholar in front of him.

"Yes!" Liu Ye nodded, "Ma Jun is not coming forward to pay homage to his lord!" Liu Ye said to the young man next to him.

"Mr. Ma Jun, the right assistant minister of the Ministry of Works, met. I have met the lord." It turned out that the young man was called Ma Jun.

"Ma Jun?" Liu Mang sounded a little familiar with the name.

"Are you Ma Jun?" Before Liu Mang could speak, Xu Shu next to him was surprised.

"Yuan Zhi, do you know this Ma Jun?" Liu Mang asked Xu Shu in surprise.

"I know! How can I not know you!" Xu Shu said with a wry smile at Liu Mang, "Lord, do you still remember the time when Liu Bei from Yuzhou and Zhang Xiu's alliance in Nanyang besieged me in Yangzhou?"

Liu Bei and Zhang Xiu joined forces to attack Yangzhou. Liu Mang wouldn't remember how he was. That was the crisis in Yangzhou, and Yangzhou was almost overturned by them.

"So?"

"When I was guarding Shouchun, the crossbows above the city were knocked out by Liu Bei's army's stone throwing machine. They were also those stone throwing machines that allowed Liu Bei's army to come to the city wall. General Deng Chao was also killed by Zhang Fei with one knife, and Shouchun was almost thrown into my hands!" Xu Shu explained to Liu Mang.

"I know these? But what does it have to do with this Ma Jun?" The crossbow at that time was the second generation. It has a low range and is prone to damage. It has no power beyond three hundred steps.

"And this Ma Jun, why didn't you tell me if you got such a person? Are you really afraid that you wouldn't tolerate others? If this explosion is the only one, you two will have a good fortune. Isn't this the biggest loss in Yangzhou? Liu Ye, do you think I should punish you?"

"It's right, it's right!" Liu Ye said with a straight head.

"You should have been punished to go back and think about your mistakes, when will you figure it out, and when will you come to the Ministry of Works again, but when will you get the gunpowder come out, so you will make up for your mistakes. But if there is another time, you will never give up. It will be light for you to be dismissed from office." Liu Mang said sternly.

"This lord, this is not my uncle's sin. It's my Ma Jun who is too eager for success." Ma Jun wants to speak to Liu Ye again. These two nephews are loyal. Liu Ye and Ma Jun are both people who have learned the Mo family. Liu Ye is not all Mo family, but he is also very concerned about the Mo family's organs. Ma Jun was born in the study of Mo family. When Ma Jun saw Liu Ye, he reported to his home. Liu Ye was shocked when he heard this, because Ma Jun's master's master was the old man Liu Ye had learned. Therefore, these two people were able to recognize the uncle and nephew.

This time, my nephew and uncle were practicing, and then I made the gunpowder. Unexpectedly, something happened when they came out. Ma Jun was too anxious. He felt itchy when he looked at the books brought back by Liu Mang. He wanted to try the cannons and muskets, which caused the industrial area to explode. Fortunately, the two of them still knew to stay away from gunpowder, otherwise they would not be able to escape and all of them would go to see their ancestors.

"Ma Jun retreat!" Liu Mang was scolded, and it was too late for Liu Ye to like him. If Liu Mang didn't blame you, it would be two things that would have been revealed for so long. The first is that you are not far from death, because Liu Mang would not blame you. He wanted to kill you directly. Another is that the lord was going to alienate you and didn't want to use you anymore. No matter which one it was, it was not what Liu Ye wanted.

"Hmph, Ma Jun, do you think you can run away? You used to build a stone thrower that hurt me so much!"

"Master, you?" Liu Ye asked in confusion. Didn't your lord Liu Mang say he wouldn't care?

"But before you practice, each of you will be his own masters, so you can be punished for death, so you will be punished. Stay in Yangzhou for the rest of your life and serve my Yangzhou. If you rebel, you will be killed without mercy." After listening to Liu Mang's words, Liu Ye breathed a sigh of relief. Liu Mang raised his slap and fell down gently, and he would not hurt his skin at all. Not to mention Ma Jun, no matter who you are, if you betray Yangzhou, if you want to betray Yangzhou, if you want to betray Yangzhou, you will not hurt your skin.

"Ma Jun, thank you lord!" Liu Ye said to Ma Jun who was still standing there.

"Oh, Ma Jun, thank you, I wish you a lord, thank you, lord, no, you're the kindness of killing." Ma Jun immediately knelt down and he returned to his stuttering expression.

"Haha, I know that Ma Jun, your head is definitely sincere!" Liu Mang said to Ma Jun and others with a smile.

"Okay, get up."

"Ma Jun is a man from Fufeng." Liu Mang's sudden question made people stunned.

"How do you know?" Ma Jun believed that he had never met Shu King Liu Mang. This was the first time he met.

"Haha, I know." Liu Mang didn't explain much, at least he confirmed one thing. This Ma Jun should be the great inventor of the Three Kingdoms in history, Ma Jun, and the stuttering and Fufeng people were the ones who were Ma Jun and Ma Deheng.

This person is amazing. Ma Jun was poor when he was young and had a stuttering problem. Therefore, he was not good at speaking but was skilled in thinking. He built a guide truck and transformed a silk weaving machine to improve the craftsmanship by four or five times. Ma Jun also developed a tool keel water truck (overturned), used for agricultural irrigation. Since then, Ma Jun also rebuilt Zhuge crossbows, which contributed to scientific development and technological progress.

Even if Zhuge Liang and others are above the institutional studies, they may not necessarily be Ma Jun's opponent.

Only Ma Jun was left thinking about where to meet His Highness the King of Shu. Other Yangzhou civil and military officials were no longer surprised.

"Zi Yang, how much has the gunpowder reached?" Liu Mang asked Liu Ye.

"Lord, gunpowder has been made, but how can I have a container to fire him? As for the cannon that the lord mentioned, hey, Ziyang is not talented. I am really helpless." Liu Ye said to Liu Mang. Gunpowder has been made, but there was a problem with Liu Ye and the others during the test firing.

The cannon written in the book looks like a gunpowder and then a projectile is placed inside. They all follow what the book says, but in the end, they find that the enemy has not been knocked out and they have blown away.

This is not a weapon to kill the enemy. This is obviously a weapon to commit suicide.

"You have also built a cannon barrel?" Liu Mang asked Liu Ye and others in confusion.

"Yes!" Liu Ye nodded.

"Go and take it and see," Liu Mang frowned. If he followed what was written in the book, it would not have exploded.

It's really not easy to get this cannon barrel. It's all made of cold light made of fine iron.

Liu Mang stroked the surface of the cannon barrel, what a huge thing. Liu Mang couldn't help but nod.

"Did you put too much gunpowder?" Liu Mang asked in confusion. If you put too much gunpowder, it would indeed explode.

"No!" Liu Ye shook his head. Although they wanted to put more gunpowder because they could hit farther, Liu Ye conservatively gave up. This time he just put it in appropriately. "It was fine at the beginning, we fired two guns. We could indeed bombard it and bring powerful destructive power, but when we shot the third gun, it exploded directly."

"Huh?" Liu Mang turned to look at the cannon barrel. It was really good outside. Liu Mang stroked his hand gently and suddenly frowned because there was a sunken place on the cannon barrel, which made people feel uncomfortable to touch.

Liu Mang lowered his head and pulled his hand straight into the cannon barrel.

"Lord, be careful!" When Liu Mang took out his hand, it had been cut and blood flowed out of the wound. Guan Hai and others on the side were about to help Liu Mang bandage, but they were stopped by Liu Mang.

Even such a big wound can be held back when fighting on the battlefield, let alone such a small one.

Liu Mang used his mouth to suck out the dirty blood from the wound on his hand and ignored him.

"There is a problem with this gun barrel." Liu Mang said to Liu Ye and Ma Jun.

"Bombing barrel?" Liu Ye walked forward in confusion. This cannon barrel was built by him supervising it, and there was absolutely nothing to lose.

"It's not this problem, but the barrel is too brittle. The inner chamber of the barrel is full of bubbles. This is not handled well during quenching, so that the air enters when the steel solidifies. Adding burrs on it, it's not okay to have such a barrel, but if you really try the gun, it's brittle, and there will be ghosts if you don't explode.

"So what kind of barrel?"

Liu Mang was not easy to explain to Liu Ye that there were all vents in the cannon tube. The willingness to produce vents is that the fire is difficult to control and cannot be decided. The amount of vents is the reason for the fluidity, and other things that are not melted sufficiently are caused by the cannon explosion this time.

Taking out such a gun barrel will only harm your own people.

"Switch it to copper products." Liu Mang said to Liu Ye and Ma Jun next to him.

"Copper cannon barrel?" Liu Ye and Ma Jun were both stunned. Steel should be obviously better forged than copper. And you have to know that copper represents money, copper coins, copper coins. This cannon has a thousand pounds. If you want to use copper, it must be a thousand pounds. How much does a thousand pounds of copper cost? And it is not just a casting one.

"Will this be a little too extravagant?" Liu Ye asked.

"Lord, this bronze ware is better than iron ware." Ma Jun immediately stopped stuttering in his profession, and his tone became unpolite during discussions with Liu Mang. This bronze weapon was no longer used in the early Han Dynasty. Everyone was proud of being able to cast good iron ware, rather than making those bronze ware.

"Iron cannons are indeed better than copper! But now you still can't create gun barrels that do not explode, so you can only use copper. Copper can ensure that your gun barrels do not explode, but the premise must be sufficient." Liu Mang emphasized one thing.

"But!" Ma Jun was still ready to ask his questions.

"No, but if you can cast iron cannons that don't explode, I can use iron without copper." The melting point of copper is several hundred degrees lower than that of iron, so copper is easier to form.

"How much is the lord going to cast this cannon?" asked Xu Shu next to him.

"I want one hundred of three thousand cannons, and I want five hundred of thousands of cannons." Liu Mang said to Xu Shu next to him.

"So many?" Three thousand pounds are three thousand pounds. All of them are made of copper, and they require one hundred pounds. Add to five hundred thousand cannons. How much copper does it cost? You must know that copper is money, how much does it cost to make a water ticket. Xu Shu is now the inner minister of Yangzhou. The inner minister is not only responsible for military and political affairs, but also in the hands of Xu Shu. The Ministry of Commerce, the Minister of Revenue Mi Zhu, also has to be responsible to Xu Shu.

Xu Shu didn't know that the oil and rice were expensive, so he immediately started to lock the door when he was in charge.

Xu Shu immediately objected. If so many cannons were built at once, the finances of Yangzhou would be almost the same.

"Yuan Zhi didn't need to agree at once. Wait a few days later. Ziyang and the others built the three thousand cannons. It would be not too late for Yuan Zhi to object." Liu Mang said this, so Xu Shu could only nod.

...

Compared with the prosperity of Yangzhou, other states have become deserted. Jiangdong and Jingzhou, the two former overlords of the Yangtze River, can only hide at home and lick their wounds.

Even Cao Cao, who was in Xudu, was anxious because Liu Mang's speed was too fast, so fast that Cao Cao felt a little scary. It was only a winter day. Liu Mang had already taken over most of Yuzhou, and it was only a matter of time before he dominated the Central Plains. Although Jiangdong and Jingzhou were not under Liu Mang's rule, both of them were not qualified to challenge Yangzhou.

If this continues, Cao Cao will unify the north, and he will be ready to fight the entire south.

"No, no, I'm going to send troops immediately." Cao Cao was anxious. He was going to send troops to attack Yangzhou now. This Liu Mang boy in Yangzhou really made him uneasy. He was originally a Lu Bu, but Cao Cao was crushed to death. Who knew that Liu Mang had emerged suddenly, and now he turned from a defeated army into a prince, and was about to become the overlord of the south.

"Lord, now is not the time to send troops!" Cao Cao wanted to send troops, so someone would stop him. Cheng Yu immediately stepped forward to stop him. "Lord, it's important for us to take the north now. It's not too late to plot against Liu Mang's child when we get a wealthy place in the north." Cheng Yu had no good face to Liu Mang. But he also knew that now is not the time to attack Yangzhou.

"If you take down the north, take down the north, this Liu Mang boy will become a climax. What will I do to deal with him? Do you still want to fight the battle of Guandu?" Cao Cao said a little angry. Although the battle of Guandu was regarded as an outstanding work in his life by Cao Cao, he defeated the many with less, and defeated his former boss. How could Cao Cao not be excited about successfully taking over the throne? However, Cao Cao still spoke out today because the battle of Guandu was too hard. No one wanted to fight such a battle again.

"Lord, cough, cough! This Yangzhou must be conquered." A pale man next to him said with a cough.

"Your health is better," it is logical that it is now a matter of discussion, and everything should be based on political affairs, but Cao Cao couldn't help but worry when he saw this thin man.

"Thank you for your concern, Fengxiao is much better." This thin man is Cao Cao's chief think tank Guo Jia and Guo Fengxiao. Guo Jia's illness broke out completely after he went to Hebei. He is coughing all day long. If there is no good treatment, it is not far from the deadline. Before he dies, Guo Jia also wants to help the lord clear everything.

"Lord, Yangzhou must be attacked." Guo Jia said while coughing.

"Fengxiao, where are there any troops in Xudu to attack Yangzhou?" Xun You said next to him, "Although my army is here, it is about to start spring, and I will attack these two children Yuan Tan and Yuan Shang. If we divide our troops to fight, it will be unfavorable to our army." Although Yuan Shao has been defeated in the north, the lean camel is bigger than a horse. Yuan Shang and Yuan Tan are not idiots. Although they are competing for the throne, they also know that Cao Cao's hungry wolf is eyeing him. Once the two of them show their fatigue, he will pounce on you to bite you to death. So after two months of fighting, these two brothers suddenly had a tacit understanding of the toner cartridge. This is what Cao Cao most unwilling to see. If the two Yuan brothers have a more tactful mind, the two of them unite to deal with Cao Cao, then Cao Cao will be very happy.

So after the spring was up, the two brothers fought and the hatred between them was still deep, and the two sent troops to destroy the first one. It was too late to wait until the other one realized it.

The troops under Cao Cao were basically unable to move.

"Lord, I can't get more food and grass in Xundu." Xun Yu, who was next to him, also spoke. Xun Yu was responsible for the dispatch of food and grass in the entire Xundu. His words were that Xu Du could not attack Yangzhou.

"Haha, Wen Ruogongda. This attack on Yangzhou does not necessarily require our Xudu's troops!" Guo Jia said to everyone with a smile.
