Zhao Heng's war drums are the clarion call for the general attack.

With the beating of war drums, the Song army in all directions began to move.

Xiao Tzu Lin sighed that there was too much time delayed at the beginning of the war, but it is not easy to say, the more time delayed, the greater the damage caused to the people of Hebei, but the advantage is that the soldiers who came from everywhere got a good rest.

The war drums sounded in front, and the scouts in the back quickly returned to the camp to report, and several large armies immediately set off from the camp.

Yang Qiong, Lei Youzhong, and Qian Shoujun joined forces and attacked the Deqing military city.

There are hardly any Song Dynasty civilians here, but the Liao State still sent some troops to guard this place, as an important storage place for grain and grass materials in the rear, and the strategy also made the Liao army more rich and changeable.

The task of the three generals in this battle is to take this stronghold.

The city wall of the Deqing army was not as good as that of Shanzhou, so it was taken by the Liao State after only a few hours, but now it has become easier to do so.

Although there are many Liao troops, they are not good at attacking cities, nor are they long at defending cities, if there are not many defense equipment in the city, then it will be easier to counterattack the Deqing military city.

It's not that difficult, it's not that easy. And they were ordered to take it in the afternoon.

The tragic battle also broke out again in the Battle of Shanzhou, when Li Jilong decided to use a new weapon.

But the other roads continued to march, and Cao Wei's two troops approached Jiuzhou Town and Zhao Village, and gradually the two armies merged into one army. Ma Zhijie and Qin Han also gradually harassed Xiao Wu Si and merged into an army. When Li Jilong gave the order to use the new weapon, his pocket was almost compressed to the size of a radius of two hundred miles.

The farthest is less than 100 miles away from the main battlefield, and the nearest is almost only forty or fifty miles away from the main battlefield.

……

The curtain was torn off.

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

Artillery.

At first, Song Jiu thought that this technique should be easy. After all, the Ming Dynasty had it.

The truth is that it took nearly thirty years to study it. I don't know how much money has been invested. But Song Jiu also made mistakes, and the officialdom of the Ming Dynasty was extremely corrupt in history. Although there are all kinds of firearms, because of corruption, from officials to craftsmen, all of them are embezzlement, resulting in half of the firearms being unusable, and even most of the quality of firearms is not up to standard. This created the illusion that firearms did not exert greater power in the Ming Dynasty.

So Song Jiu was not very attentive, but he was too high-minded and wanted more advanced artillery. Want steel cannons.

The actual steel cannon is a mistake, the steel cannon is definitely better than the copper cannon, but the current casting technology has not gone up, and the various basic knowledge has not kept up, and the steel ductility is not as good as copper, and the toughness is not as good as copper, so the casting technology must be stricter and higher, and compared with the copper cannon, the steel cannon is not up to the technology before the artillery. It is also easy to blow up.

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

Later, seeing that it really didn't work, Song Jiu instructed to replace steel with more valuable copper. Probably, the artillery is a little less powerful and a little more expensive. However, if the research is successful, more knowledge will be accumulated, and the foundation will be laid for the emergence of steel cannons in the future. It even laid the foundation for rifle skills. This principle is like the growth of a baby, crawling first and then walking. If you don't climb, you want to go. That's unlikely.

However, Song Jiu continued to "be ambitious" and still insisted on developing rear-loading guns.

Compared to front-loading guns. Breech-loading guns have a faster rate of fire, a longer range and a more standard accuracy. Even the battery could be loaded with shells inside the bunker, which was convenient and safe.

However, compared to the front-loading gun, it is also more technical. First of all, it is necessary to engrave the rotating compound line in the barrel, Song Jiu knows the word Lu Dao, but he does not know what the specific compound line is.

As for guns and other weapons, as good Chinese citizens in their previous lives, most of them were not very proficient.

It is also necessary to have a locked gun door and a tight plug, as well as a water pressure gas brake and retraction machine that saves reset and aiming time and reduces the force on the gun mount when firing.

And thanks to the travel novel, otherwise Song Jiu would not know these terms.

As well as the requirements for the quality of the gun body, I originally wanted to use steel cannons, but the results were unsuccessful, but pure copper could not be used, in fact, there was no pure copper at this time, most of them were alloys, alloy copper containing tin, lead, zinc and other metals. But Song Jiu still remembered a term, hard bronze, which is an alloy of copper and tin.

Therefore, it returned to the copper cannon, and the progress was still very slow, and it was not until the year before last that the first test laboratory product appeared. In fact, at this time, the Song Dynasty's technique was able to make a steel cannon, but Song Jiu didn't know the specific technique of the Dao, so he could only make this helpless choice.

Subsequently, Song Jiu transferred this test laboratory to Nanhetao, without him, in order to keep it secret.

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

Its shape resembles the Ming Dynasty Franc cannon, of course, the nature is completely different, but the length and weight are similar. From the very beginning, Song Jiu did not seek to be big, including ambushes and trebuchets. If it is large, it is not easy to transport and is bulky. Moreover, the number one enemy of the Song Dynasty was still the nomads.

Therefore, it only has four types: 300 catties, 400 catties, 500 catties, and 600 catties, that is, a baggage truck can pull it away.

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

At first, it is to buy time to shrink the pocket, and the longer you fight, the more stamina the enemy will consume.

But if there is no scheduling of Cao Wei and Li Jilong in this battle, there will also be great trouble.

In any case, Song Jun won nearly two hours of precious time, and his pocket was smoothly reduced.

A thousand cannons spit out tongues of fire of death.

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

Fatally, it's not a trebuchet, the firing speed is so slow, the rate of fire is not slow, the speed is more than the speed of sound, the sound of artillery has not been heard in the front ears, and the shells in the back fly in front of you. There's a way, let's lie on the ground. However, the Liao army is almost all cavalry, where to lie down.

Therefore, patches of Liao soldiers were harvested by artillery.

Kou Zhun muttered, "It's worth the money." ”

He gradually became dissatisfied with Song Jiu, first, Song Jiu pulled Zhang Qixian up again, and second, the right. Song Jiu is in Dongfu, can he still take the throne? Can you still grab power like you did with Lu Duan? The second is the money.

After the third division looked at the account books. Seeing the military spending in it, I felt a pain in my flesh. If it works. It doesn't matter, he is not a peacemaker, and the situation in front of Guan Jian has deteriorated to that point, so is it worth spending all this money?

But now seeing the lethality of this new type of artillery, it is worth it. What's worse is that Song Jiu gave up solid shells with very little lethality, as well as shotguns with a short range, and developed flowering shells.

Of course, now the entire world is a blank piece of paper for this weapon, and Song Jiu wants to draw it. It's a square, and if you want to draw a circle, it's a circle.

This kind of small leap research cost a lot of money and extended the research and development time, and even some people in the academy proposed to abandon it at one time, but if the research is successful, the lethality will be greater than that of the same level of artillery in the Ming Dynasty.

Zhao Heng put down the drumstick and breathed a long sigh of relief: "The plan has been decided." ”

Nominally, he was also the commander-in-chief.

He also knew all the plans. The most important battle is in these two or three hours. If you hold it, you will win. Unable to hold it, the army under the city collapsed. Then it's the turn of the offensive and defensive battles. Although there is a city wall in Lanzhou, the city wall is not high, nor is it solid, and the Liao army may be under one blow. Take Lanzhou.

Before the car left, Zhao Heng thought about this problem. Song Jiu entered the palace at night and deliberately said that there would be no danger. For no other reason, it's this artillery.

However, the test was in Nanhetao, and the training was also in Nanhetao, although Zhao Heng could understand it and keep it secret, he didn't see it with his own eyes. God knows how powerful it is.

He sat down and took a sip of the medicinal soup, and then said, "Physicology." ”

Everyone was speechless.

Because the Song Dynasty used the imperial examination to employ people, it still looked down on the study of physical qualifications. Even the academy has students who have entered the officialdom, which makes those Jinshi officials who read the master's books still have some rejection in their hearts.

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

Zhao Heng asked again: "Song Jiu, there is no news of your teacher at all?" ”

Song Jiu shook his head.

"As far as I know, the West doesn't have this kind of knowledge."

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

Song Jiudao: "Your Majesty, the minister doesn't know very well, or Mr. He came to the Central Plains and was the product of the fusion of the two civilizations, but no matter what, this is the luck of my dynasty." ”

"Ha Luha," Zhao Heng smiled.

The tide of battle began to turn, and his mood became relaxed.

The sun gradually turned westward, and the Liao army was still resisting stubbornly, rushing forward and swooping down on the Song army camp one after another.

If there was no artillery suppression, Song Jiu suspected that under the desperate effort, the Song army camp might be lost.

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

Xiao Yanyan looked at the battle situation, her face was clouded. At this time, the scouts brought a lot of bad news, the Song army was attacking the Deqing military city, and the Song army was advancing, gradually closing the siege......

She called Han Derang and the important ministers in front of her, and said solemnly: "Prepare to break through." ”

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

Of course, the consequences of the breakthrough are also not good, such a long journey, the Song army is constantly ambushing and pursuing, how many soldiers can be brought back, no one can know the way, in fact, once you choose to break through, it means a fiasco.

Everyone was 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 State will find a substitute for the dead ghost to come out, and this substitute for the dead ghost must also be a heavyweight, and even Xiao Tzu Rin can't meet it. In this way, we can give an explanation to the ministry. So who will the ghost of the dead be!

Xiao Yanyan was silent for a while, and finally said, "First order to stop the attack." ”

Even if you break through, you have to think about how to break through and how to deal with the aftermath.

However, time passed imperceptibly.

Xiao Tzu Rin ordered the three armies to withdraw.

The Liao army withdrew to the camp like a tide, and in terms of casualties, the Liao army suffered heavy casualties, and the Song army may not be able to reap the benefits. However, between advancing and retreating, the morale of the Liao army was no longer as strong as it was in the morning.

Xiao Yanyan sat in the big tent, her face became darker and darker, and she asked, "Which direction do you think you are retreating from?" ”

Although the consequences of the breakout were bad, they were much better than the imminent annihilation here. She suddenly thought of Yelu Deguang, the Liao Taizong who successfully entered Kaifeng. It was precisely because of the grass valley system that the people of the Central Plains were aroused to resist, and they had to leave Kaifeng and lead the army back to the north, and died of illness on the road. On his deathbed, he summed up the three losses of this dispatch, which is why the world rebelled against me like this! The looting of people's money in various places is the first mistake; Letting the Khitan soldiers threshing grass and disturbing the people is the second mistake; Failing to repatriate the Jiedu envoys early to govern the towns is the third mistake.

He also wrote to his younger brother that I often think about ways to govern the Central Plains at night, and it seems that only the three things that are most important are to put my heart in my heart, to cooperate with the army, and to comfort the people.

If the Liao army did not burn and plunder after going south in the past, would the Song army be so desperate? Could many cities be so difficult to attack?

The simplest reason, after getting Qizhou and other cities, he ordered himself to kill and poke on a large scale, and even slaughtered the people of the entire city of the Deqing army. Can the guards of the Song Dynasty not fight hard for the lives of themselves and their families?

This may be a mystery.

Not only did he flee back and the whole country became a mess, but he also had to deal with the counterattack of the Song army. Even in the next few decades, I don't want to fight the idea of the Song Dynasty in my life.

Of course, she wouldn't sigh that she knew this earlier, so why not agree to Cao's conditions. Now she doesn't know that Lu Dao has been fooled?

Everyone also realized that they would not mention it.

There was still silence in the big tent, as far as they knew, the army in the west was "the worst" in combat effectiveness, but the west was Taihang Mountain, could it be that from Jingcheng Pass into Taihang Mountain, and then escape back to Liao from Hedong? Then it's better to fight to the death.

Then there is due north, and east, not to mention that a few tigers in the east will make everyone feel the same cold, and the east breakthrough is undoubtedly a detour. But breaking through from the north, with so many troops in the north, can they break through?

There was silence in the big tent, and the soldiers outside were making fires to make food, and the Liao State had two meals, but they still had to fight, so they cooked in advance to increase their physical strength.

At this moment, one after another black shadows with countless snows gradually spread up. (To be continued......)
