The sound of Zhao Heng's war drums was the clarion call for a general attack. With the sound of war drums, Song troops from all directions began to take action. Xiao Talin lamented that too much time was wasted at the beginning of the war, but it was hard to say. The more time was wasted, the greater the harm to the people of Hebei. However, the good thing was that the soldiers who came from all over got a good rest. The war drums sounded in front, and the scouts in the back quickly returned to camp to report, and several armies immediately set off to camp. Yang Qiong, Lei Youmin and Qian Shoujun joined forces and attacked the Deqing military city. There are almost no people from the Song Dynasty here now, 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. Strategically, the Liao Army became more varied. The mission of the three warriors in this battle is to capture this stronghold. The city walls of the Deqing army were not as strong as Chanzhou, so they were captured by the Liao after only defending for a few hours. But now it has become easier to do the opposite. Although the Liao army was large, they were not good at attacking cities, nor were they good at defending cities. If there were not many defensive equipment in the city, it would be easier to counterattack the Deqing military city. Not that difficult, not that easy. Moreover, the order they received was that they must capture it at the end of the afternoon. The tragic war broke out again when Li Jilong decided to use new weapons in the battle of Chanzhou. But other groups continued to march. Cao Wei and his troops moved towards Jiuzhou Town and Zhao Village, and gradually the two armies merged into one army. Ma Zhijie and Qin Han also gradually moved closer to Xiao Wu and formed an army together. When Li Jilong ordered the use of new weapons, his pocket was almost compressed into a radius of 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. ?¡ ?The curtain was pulled down. A thousand strange weapons were revealed behind the Song army. Artillery. At first, Song Jiu thought that this technology should be easy, after all, it was already available in the Ming Dynasty. The fact is that it took nearly thirty years to study it. The amount of money invested is unknown. But Song and Nine also made mistakes. Historically, the officialdom of the Ming Dynasty was extremely corrupt. Although there were various firearms, everyone from officials to craftsmen was corrupt because of corruption. As a result, although firearms are available, half cannot be used, and most of them are even of substandard quality. This created the illusion that firearms did not exert greater power in the Ming Dynasty. So Song Jiu was not very concerned about it. If he was, he set his sights too high and wanted more advanced artillery. I want a steel cannon. "The actual steel cannon is a mistake. Steel cannons are definitely better than copper cannons. However, the current casting technology has not improved, and various basic knowledge has not kept up. Moreover, the ductility of steel is not as good as copper, and the toughness is even worse than copper. Therefore, the casting technology must be more stringent, and compared with copper cannons, steel cannons are more likely to explode before the technology catches up. Therefore, Song Jiu¡¯s Great Leap Forward-style guidance took many detours. Later, when he saw that it was not possible, Song Jiucai gave instructions to replace steel with more precious copper. The artillery may be less powerful and more expensive. However, if the research is successful, more knowledge will be accumulated, which will lay the foundation for the emergence of steel cannons and even rifle technology in the future. This principle is like the growth of a baby, crawling first and then walking. It's impossible to walk without crawling. "But Song Jiu continued to "aspire too high" and still insisted on developing breech-loaded cannons. Compared with front-loaded guns, breech-loaded guns have a faster rate of fire, a longer range, and more accurate accuracy. Even the fort can be loaded with artillery shells in the bunker, which is convenient and safe. But compared with the front-loading gun, its technology is also higher. First the rotating rifle lines had to be carved into the barrel. Song Jiu knew the word, but didn't know the specific rifle. ??As good Chinese citizens in previous lives, most of them are not very knowledgeable about guns and other weapons. It is also necessary to have a locking gun door and a tight plug, as well as to save reset and aiming time. A hydraulic gas retractor that reduces the force on the gun mount when the gun is fired. And thanks to the time-travel novel, otherwise Song Jiu wouldn¡¯t know these terms. As well as the requirements for the quality of the cannon body, I originally wanted to use a steel cannon, but it was unsuccessful. However, pure copper could not be used. In fact, there was no pure copper at this time. Most of them were alloys, alloys containing metals such as tin, lead, zinc, and manganese. copper. But Song Jiu still remembers a term, hard bronze, which is an alloy of copper and tin. So back to the bronze cannon, progress was still very slow. It was not until the year before last that the first laboratory product appeared. In fact, the Song Dynasty's technology could create steel cannons at this time, but Song Jiu didn't know the specific technology and could only make this helpless choice. Song Jiu then transferred the laboratory to Nanhetao for the sake of confidentiality. Then last year, Pan Weizheng was asked to go to Nanhetao to train artillery. Its shape typeThe Fran cannons of the Ming Dynasty were of course completely different in nature, but their length and weight were similar. From the beginning, Song Jiu not only pursued greatness, including Fulu slaves and trebuchets. It is difficult to transport when it is large and bulky. Moreover, the number one enemy of the Song Dynasty was still the nomads. Therefore, it only has four types: 300, 400, 500, and 600 jins, which means it can be pulled away by a baggage truck. There are still many shortcomings, but it can be used, and its range reaches 800 meters to 1,500 meters. Two of the small guns can be carried away by horses and rush to the battlefield quickly. It is not used at first, it is to buy time to shrink the pocket, and the longer the battle lasts, the more energy the enemy will consume. But without the coordination of Cao Wei and Li Jilong, this battle would also be in great trouble. No matter what, Song Jun won precious nearly two hours, and his pockets were successfully reduced. A thousand cannons spit out tongues of death. Every time a shell fell, it almost took away the lives of one or two Liao soldiers. The terrible thing is that it is not a trebuchet. The firing speed is so slow, and the rate of fire is not slow. The speed exceeds the speed of sound. The ears in front have not heard the sound of the artillery, but the shells from the back are flying in front of you. If you have a way, just lie down on the ground. However, the Liao army was almost all cavalry, so they would lie wherever they could. Therefore, scores of Liao soldiers were harvested by artillery. Kou Zhun murmured: "This money is well spent." He gradually became dissatisfied with Song Jiu. First, Song Jiu brought Zhang Qixian up again, and second, power. Song Jiu was in Dongfu, could he still be in power? Can we still seize power like we did with Lu Duan? The second thing is the money. After he looked over the account books at the Third Division. It hurts my heart to see the military expenditure involved. If it works, it doesn't matter. He is not a peace seeker. Guan Jian doesn't know how far the situation has deteriorated. So is it money well spent? But now that I see the lethality of this new artillery, it¡¯s so worth it. The terrible thing is that Song Jiu gave up the solid bullets with little lethality and the short-range shotgun shells, and developed blooming shells. Of course, now the whole world is a blank sheet of paper for this kind of weapon, and Song Jiu wants to draw a square. It is a square. If you want to draw a circle, it is a circle. This kind of small leap-forward research cost a lot of money and extended the development time. At one time, some people in the academy even proposed to abandon it. But if the research is successful, the lethality will be greater than the artillery of the same level in the Ming Dynasty. Zhao Heng put down the drumstick and breathed a sigh of relief: "The plan has been decided." In name, he is still the commander-in-chief. He also knows all the plans, and the most important battle will take place within these two or three hours. If you hold on, you will win. Unable to hold on, the army under the city collapsed. Then it's the turn of the offensive and defensive battle. Although there is a city wall in Chanzhou, the wall is not high, not large, and is not strong. The Liao army may be able to take Chanzhou in one go. Before setting off, Zhao Heng thought about this problem. When Song Jiu entered the palace at night, he deliberately said that if there was a surprise, there would be no danger. For no other reason, it was this artillery. ¡° However, the test was in Nan Loop, and the training was also in Nan Loop. Although Zhao Heng could understand that it should be kept secret, he had not seen 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: "The study of Wu Ge." Everyone was speechless. Because the Song Dynasty relied on imperial examinations to appoint people, it still looked down upon the study of physical objects. Even academies have students entering officialdom. Those Jinshi officials who read Confucius' books felt a little repelled in their hearts. However, everyone was shocked when they saw this weapon today. Zhao Heng asked again: "Song Jiu, there is no news at all about your teacher?" Song Jiu shook his head. "As far as I know, there is no such knowledge in the West." "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, and brought back some novel insights, and indeed saw It has a different civilization and relatively backward science from the Central Plains, but there is still a huge gap between it and the materialism of Song and Nine Dynasties. Song Jiu said: "Your Majesty, I don't know for sure, maybe it is the product of the fusion of 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 situation of the battle began to turn around, and his mood became more relaxed. As the sun gradually turned to the west, the Liao army was still resisting stubbornly, rushing forward and successively towards the Song army camp. Without artillery suppression, Song Jiudu suspected that the Song Army's camp might have been lost under desperate efforts. However, the huge destructive power of the artillery finally made many Liao soldiers feel scared. Xiao Yanyan looked at the battle situation with a clouded face. At this time, the scouts brought a lot of bad news. The Song army was attacking the Deqing military city. The Song army was advancing and graduallyEncirclement She called Han Derang and other important ministers in front of her, and solemnly said: "Get ready to break out." If this stalemate continues, it will be very disadvantageous if more Song troops encircle them. Of course, the consequences of breaking out are also very bad. During such a long journey, the Song army continued to ambush and pursue. No one knows how many soldiers they can bring back. In fact, once they choose to break out, it means a disastrous defeat. Everybody was silent. Xiao Yanyan said angrily: "What do you mean, sir?" Han Derang looked ashen and said: "Then break out." Once that happens, the Liao Kingdom will find a scapegoat, and this scapegoat must be a heavyweight, even Xiao Tarrin can't even fit it. In this way, we can give an explanation to all the departments. Then who will be the scapegoat! Xiao Yanyan was silent for a long time, and finally said: "First give the order to stop the attack." Even if you break through, you must think about how to break out and how to deal with the aftermath. However, time passed unconsciously. 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 reap any benefits. However, between the advance and retreat, the morale of the Liao army was no longer as strong as it was in the morning. Xiao Yanyan sat in the tent, her face getting darker and darker, and asked: "Which direction do you think you will retreat from?" Although the consequences of breaking out are very bad, it is much better than the imminent annihilation of the entire army here. She suddenly thought of Yelu Deguang, Emperor Taizong of the Liao Dynasty who successfully entered Kaifeng. It was precisely because of the grass-grazing system that the people of the Central Plains rebelled. Finally, they had to leave Kaifeng, lead the army back north, and died of illness on the way. Before he died, he concluded that this time he sent troops and made three mistakes, so the world rebelled against me like this! Looting people's money from various places was the first mistake; letting Khitan soldiers thresh grain and grass to disturb the people was the second mistake; not sending back the Jiedushi envoys to govern the towns early was the third mistake. 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 most important things are to confide in one's heart, to reconcile military affairs, and to appease the people. If the Liao army had not burned, killed, and looted when they went south, would the Song army have been so desperate? Will many cities be so difficult to attack? The simplest reason is that after acquiring Qizhou and other cities, he ordered a massacre, and even massacred the entire Deqing army and the people in the city. Could the guards of the Song Dynasty not fight tooth and nail to keep themselves and their families alive? This may be a mystery. Not only did he escape and turn the whole country into a mess, he also had to deal with the Song army's counterattack. Even in the next few decades and throughout his life, he did not want to have any idea of ????the Song Dynasty. Of course, she would not regret that she had known this earlier, so why not agree to Cao's conditions. Doesn't she know that she was fooled now? ??Everyone is also conscious and will not mention it. There was still silence in the big tent. According to what they knew, the army in the west had the "worst" combat effectiveness, but to the west was the Taihang Mountains. Could it be that they entered the Taihang Mountains from Jingxing Pass and then fled back to the 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, everyone is equally disappointed. Breaking out from the east is undoubtedly a detour. But if we break through from the north, can we break through with so many troops from the north? There was silence in the big tent, and the soldiers outside were making fire and cooking. In the Liao country, they usually had two meals, but they still had to fight, so they cooked in advance to increase their physical strength. At this moment, groups of black shadows gradually came up, carrying countless amounts of snow.
