The sound of Zhao Heng's war drums is the clarion call of the general attack.

With the sound of war drums, the Song army from all directions began to act.

Xiao Talin sighed that the war Chu had been delayed too much time, but it was hard to say. The delayed time would cause even more harm to the people of Hebei. However, the advantage was that the soldiers coming from all over the place had a good rest.

The war drums in front were pounding, and the scouts behind quickly returned to the camp to report, and several large armies immediately set off.

Yang Qiong and Lei had an end, and Qian Shoujun's army met and attacked the Deqing Army City.

There is almost no ordinary people in the Song Dynasty here, but the Liao Kingdom still sent some troops to guard this place as an important food and material saving location in the rear, and strategically it also made the Liao army more varied.

The three generals' mission in this battle is to take down this stronghold.

The city wall of the Deqing army was not as good as that of Chanzhou, so it was taken down by the Liao Kingdom after only a few hours of defense. However, now it has become easier to do so.

Although there were many Liao troops, they were not good at siegeing cities, nor were they good at defending cities. If there were not many defending equipment in the city, it would be easier to counterattack the Deqing army city.

It was not that difficult, nor so easy. And the order they received was that they had to take it down in the afternoon.

The tragic war broke out again when Li Jilong decided to use his new weapon in the Battle of Chanzhou.

But the other routes continued to march. Cao Wei and his troops relied on the quarrels at Jiuzhou Town and Zhao Village, and gradually the two armies joined forces to form an army. Ma Zhijie and Qin Han troops also gradually moved on to Xiao Wu and became an army. When Li Jilong ordered the use of the new weapon, his pocket was almost compressed to a size of about two hundred miles.

The farthest one is less than a hundred miles away from the main battlefield, and the closest one is almost only forty or fifty miles away from the main battlefield.

...

Bring off the curtain.

A thousand strange weapons were exposed in the rear of the Song army.

artillery.

At first, Song Jiu thought that this technology should be easy, after all, it was found in the Ming Dynasty.

The fact is that it took nearly thirty years to study it. I don’t know much money. But Song Jiu also made mistakes. In history, the official atmosphere in the Ming Dynasty was extremely corrupt. Although there were all kinds of firearms, due to corruption, all from officials to craftsmen were embezzling. Although there were firearms, half of them could not be used, and most of them were unqualified in quality. This caused the illusion that firearms did not exert greater power in the Ming Dynasty.

So Song Jiu was not very concerned about it, but he was too focused on it, and wanted more advanced artillery and steel cannons.

In fact, steel cannons are a mistake. Steel cannons are definitely better than copper cannons, but the current casting technology has not improved, and various basic knowledge has not kept up, and steel is not as ductile as copper, and its toughness is not as strong as copper. Therefore, casting technology must be stricter and higher, and compared with copper cannons, steel cannons are prone to explode before technology keeps up.

Therefore, Song Jiu's guidance on the Great Leap Forward is equivalent to taking many detours.

Later, when he saw that it was really not possible, Song Jiucai guided the use of more expensive copper instead of steel. The cannon may be less powerful and more costly. However, if the research is successful, more knowledge will be accumulated, and in the future it will lay the foundation for the emergence of the cannon, and even lay the foundation for the rifle technology. This principle is like the growth of a baby, climbing first and then walking. If you don’t climb, you want to walk, which is impossible.

But Song Jiu continued to be "out of mind" and insisted on R&D and post-installation.

Compared with the front-loading gun, the rear-loading gun has a faster firing rate, a longer range and a more standard accuracy. Even the turret can load shells in the bunker, which is both convenient and safe.

However, compared with the front-loading gun, its technology is also higher. First, it must be carved into the barrel to rotate and repeat the line. Song Jiu knew this word, but he didn't know what to repeat the line.

As good Chinese citizens in their previous lives, most of them are not very expert in guns and cannons.

There must also be a water-pressure gas-type retracting machine that locks the gun door and tight plugs, as well as save reset and aiming time and reduces the force of the gun mount when firing.

There is also a thank you for the time travel novel, otherwise Song Jiu would not know these nouns.

As for the requirements for the quality of the gun body, I originally wanted to use a steel cannon, but it was not successful. However, pure copper could not be used. In fact, there was no pure copper at this time, mostly alloys, alloy copper containing metals such as tin, lead, zinc, and other metals. But Song Jiu still remembered a noun, hard bronze, which is the alloy of copper and tin.

Therefore, when it comes to copper cannons, the progress is still very slow. It was not until the first laboratory product appeared the year before. In fact, the Song Dynasty's technology could make steel cannons at this time, but Song Jiu did not know the specific technology, so he could only make such a helpless choice.

Then Song Jiu transferred the laboratory to Nanhetao, nothing else, to keep it confidential.

Then last year, Pan Weizheng was asked to go to Nanhetao to train artillery.

Its shape is similar to the Fran cannon of the Ming Dynasty. Of course, its properties are completely different, but their lengths and weights are similar. From the beginning, Song Jiu did not seek big things, including Fulu and catapults. When it is big, it is not easy to transport and is bulky. Moreover, the number one enemy of the Song Dynasty was still a nomadic people.

Therefore, it only has four types: three hundred, four hundred kilograms, five hundred kilograms, and six hundred kilograms, which means that a logistics truck can pull it away.

There are many disadvantages, but they can be used, and the range reaches 800 to 1,500 meters. Two of the small cannons can be carried away by horses and quickly rushed to the battlefield.

It is not used at first, which is to win time to narrow your pockets, and the longer the battle, the more physical energy the enemy will consume.

But if Cao Wei and Li Jilong were not dispatched in this battle, there would be great trouble.

No matter what, the Song army won the precious nearly two hours and his pockets were also shrunk smoothly.

A thousand cannons spit out the tongue of death.

Every time the shell fell, it almost took away the lives of one or two Liao soldiers.

The fatal thing is not a catapult. Its firing speed is so slow and its firing speed is not slow. Its speed exceeds the speed of sound. Before the sound of artillery was heard in front of the ears, the shells flew in front of me. There is a way to lie on the ground. However, the Liao army was almost all cavalry, so where did they lie on.

Therefore, the Liao soldiers were harvested by artillery.

Kou Zhun murmured: "This money is worth spending."

He gradually became dissatisfied with Song Jiu. One was that Song Jiu brought Zhang Qixian up again, and the other was power. Song Jiu was in the East Mansion, could he still take power? Can he still seize power like Lu Duan? Secondly, it was this money.

After Sansita read the account book, he felt a pain when he saw the military expenses. If it worked, it didn't matter. He was not a peacemaker, and he was concerned about the deterioration of the situation ahead. So is this money worth it?

But now seeing the lethality of this new type of artillery is too worthwhile. The worst thing is that Song Jiu gave up the solid bullet with very little lethality and the shotgun with a short range, and developed the flowering fire shell.

Of course, the whole world now has a blank piece of paper for this weapon. Song Jiu wants to draw a square. It is square. If you want to draw a circle, it is circle.

This kind of small jump-up research cost a lot of money and extended the research and development time. At one point, someone in the academy proposed to give up it. But if the research was successful, the lethality would be greater than the artillery of the same level in the Ming Dynasty.

Zhao Heng put down the drumsticks and breathed a sigh of relief: "The plan is decided."

In his name, he is also the commander-in-chief.

He also knew all the plans that the most important battle was to defend within these two or three hours, and you would be sure to win. If you could not defend, the army under the city collapsed. Then it was the turn of offensive and defensive battle. Although there was a city wall in Chanzhou, the city wall was neither high nor large nor solid, and the Liao army might take down Chanzhou in one go.

Before the car drove away, Zhao Heng thought of this problem. Song Jiu entered the palace at night and deliberately said that there was no danger in the event of shock and no danger, but because of this cannon.

However, the experiment was in Nanhetao, and the training was also in Nanhetao. Although Zhao Heng could understand it and kept it secret, he did not see it with his own eyes. God knows how powerful it is.

He sat down and took a sip of the medicine soup, and said, "Learn things."

Everyone was speechless together.

Because the Song Dynasty used the imperial examination to hire people, they still looked down on the subject-mastery. Even students in the academy entered the officialdom, which made those Jinshi officials who read the Master's books still repelled in their hearts.

However, when I saw this weapon today, everyone was shocked.

Zhao Heng asked again: "Song Jiu, your teacher has no news at all?"

Song Jiu shook his head.

"As far as I know, the West does not have this knowledge, either."

It has nothing to do with Zhao Heng. Since Zhao Kuangyin, he has sent a group of people to the Western Regions, even to Central Asia, and Byzantium, bringing back some novel insights. He has indeed seen different civilizations from the Central Plains and relatively backward science, but there is still a huge gap with Song Jiu's materialism.

Song Jiu said: "Your Majesty, I don't know much, or the product of the integration of the two civilizations after he came to the Central Plains, but no matter what, this is the luck of our dynasty."

"Haha," Zhao Heng smiled.

The battle began to reverse and he felt relaxed.

The sun gradually turned westward, and the Liao army was still resisting stubbornly, rushing forward and towards the Song army camp.

If there were no artillery suppression, Song Jiu would have suspected that the Song army camp might have been lost after fighting.

However, the huge lethality of the artillery finally made many Liao troops feel scared.

Xiao Yanyan looked at the battle situation and her face was covered with clouds. At this time, the scout brought a lot of bad news. The Song army was attacking the Deqing army city, and the Song army was advancing and gradually encircled...

She called Han Derang and the important officials to her and said solemnly: "Prepare to break through."

If this stalemate continues, it will be very unfavorable once more Song troops surround him.

Of course, the consequences of breaking through are also very bad. After such a long journey, the Song army kept ambushing and chasing, and no one could know how many soldiers could be brought back. In fact, once they chose to break through, it would mean a crushing defeat.

Everyone remained silent.

Xiao Yanyan said irritably: "What do you mean?"

Han Derang's face turned gray and said, "Then break through."

Once that happens, the Liao Kingdom will find a scapegoat, which must be a heavyweight figure, and even Xiao Talin cannot match it. In this way, we can give the tribes an explanation. So who will the scapegoat be!

Xiao Yanyan was silent for a while and finally said, "Order to stop the attack first."

Even if you break through, you must think about how to break through and how to recover.

However, time passed without realizing it.

Xiao Talin ordered the three armies to withdraw.

The Liao army retreated to the camp like a tide. In terms of casualties, the Liao army suffered heavy casualties, and the Song army may not be able to make any benefits. However, as soon as they advance and retreat, the morale of the Liao army was not as strong as that in the morning.

Xiao Yanyan sat in the tent and looked darker and asked, "Which direction do you think you will retreat?"

Although the consequences of breaking through were very bad, it was much better than the result of the annihilation of the entire army here. She suddenly thought of the Emperor Taizong of Liao, Yelu Deguang, who successfully entered Kaifeng. It was precisely because of the grass-drawing system that aroused the resistance of the people in the Central Plains that they had to leave Kaifeng and lead the army northward to return, and died of illness on the road. Before his death, he summarized the three mistakes of sending troops this time, so the world rebelled against me like this! The first mistake was to plunder the people's money in various places; the second mistake was to let Khitan soldiers thresh grain and disturb the people; the third mistake was not to repatriate the Jiedushi to manage the towns early.

He also wrote to his younger brother, saying that I often think about ways to govern the Central Plains at night. It seems that the three things that are the most important to be honest, to cooperate with military affairs, and to soothe the people.

If the Liao army had not burned, killed and plundered after going south in the past, would the Song army be so desperate? Will the many cities be so difficult to attack?

The simplest truth is that after getting the cities of Qizhou and other cities, he ordered to kill and stab the people of the Deqing army and even massacred the people of the whole city. How could the guards of the Song Dynasty not fight for their own and their families?

This may be a mystery.

Not only did it become a mess to escape back to the entire country, but it also had to deal with the counterattack of the Song army. Even in the next few decades, I would not want to make the Song Dynasty's idea in my life.

Of course, she would not sigh that she had known this, so why didn't she agree to Cao's conditions? Don't she know she was fooled yet?

Everyone also consciously did not mention it.

The big tent was still silent. As far as they knew, the army in the west had the "worst combat effectiveness," but the Taihang Mountains were on the west. Could it be that they entered Taihang Mountains from Jingxing Pass and then fled back to Liao Kingdom from Hedong? It would be better to fight to the death.

Then there is the north and the east. Not to mention the tiger generals in the east, it makes everyone feel equally disappointed. Breaking through the east is undoubtedly a detour. But can we break through from the north and so many troops in the north be able to break through?

The tent was silent, and the soldiers outside were making fires to make meals. Most of the Liao Kingdom had two meals, but they had to fight, so they cooked in advance to increase their physical strength.
