Of course, he has a trump card that has not been used, the troops of Saili and Wang Bailong have not yet been put into battle, and several living armies have been put into the battlefield, and it is likely to defeat the Song army, and it can even be said that the victory is in hand. 『』[Burn^文^书库][]. [774] [buy].]. d.m [Read the latest chapter section for the first time: {Biyu Chinese Netщщщ.Ыqi.mЁ}]

However, there was one thing he couldn't make up his mind, even if he threw in a few troops too early, he could only defeat Quduan. The Jin army was fully deployed, and there was no reserve anymore, so it was impossible to effectively contain the Song army's reinforcements, so what he wanted was to complete the mobilization of troops, completely defeat the left flank of the Song army, and suppress the main force of Quduan between Luoshui and Gushui, forming a large-scale war of annihilation. Yishui appeared in the Song army, which made him can't help but scold Qu Duan, this guy is too slippery, he simply calculated the time, and occupied the favorable terrain, leading him by the nose, and the reinforcements of others arrived neither early nor late, which put him in a dilemma.

Fighting is not a game, let alone a meal, just hug and fight and kill, as an experienced marshal, he understands very well the significance of the Song army behind the Jin army at the critical moment, especially when he is implementing the deployment of troops, which can be said to be the weakest time. Even if the Song army did not seize the opportunity, as long as he cooperated with the reinforcements to defeat his left flank, even if he defeated the left flank of the Song army and cut off the connection between his main force and the camp, it would be useless, at most it would be a draw.

"Lang Jun, Brother Yinshu Lang Jun urgently reported and asked for reinforcements."

"Why didn't Brother Yinshu put all the horse army into it?"

"Yishui discovered the activities of the Song people, and Yinshu Brother Langjun was afraid that there would be soldiers from the Southern Dynasty, so he didn't dare to use the remaining horse army."

"Confused." Sticky Han secretly scolded Brother Yinshu, the left flank was defeated, and the whole army had almost no possibility of winning, instead of shrinking back, it was better to fight hard to buy more time for the whole army, so that the main force of the right wing could complete the fatal blow.

As for Wang Yuan's arrival on the battlefield, as long as the reserves are not used, he can completely retreat calmly, and even launch a counterattack against Wang Yuan.

"Go back and tell Brother Yinshu, don't have any reservations, be sure to turn the tide of the battle for me." Mu Han had already decided to abandon the left flank and gather the forces of the right flank for a decisive battle, and be sure to defeat Qu Duan before Wang Yuan arrived, at least he would not lose face too much.

It can be said that Wang Yuan's unintentional arrival caused huge pressure on the Jin army, and the Song army's military formation was not so easy to break, even if the left flank of the Song army was defeated, they could hold out for a long time, and they could use Wang Yuan's reinforcements to regenerate themselves and fight a decisive battle again. The strength of the Jin army on the battlefield was not enough to fight on both sides at the same time, and as a result, Muhan was very depressed.

In other words, Wang Xiu forgot about eating, forgetting about the Battle of Jingxi, and even more about the breakthrough of Wushu, and he was completely immersed in Lin Shilang's description.

Gunpowder, as the name suggests, is a combination of sulfur, saltpeter and charcoal, without any mystery, and the art of making zuò was mastered in this era and continued to develop.

At this time, the development of gunpowder was quite mature, and powdered black powder was widely used, which could use the burning jet of gunpowder to fire strong crossbow arrows. Rockets, fireballs, thistles have been widely used, and even heavy firearms such as thunderbolts and earth-shaking thunderbolts have also appeared one after another. Light shockwaves can stun people to death.

The court of the Great Song Dynasty also attached great importance to firearms, unified the manufacture of firearms nationwide, and the ten institutes of the military weapons superintendent, gunpowder and firearms each accounted for one share, and the military state manufacturing institutes also produced gunpowder, which was quite popular.

It's a pity that in Wang Xiu's eyes, the power of powdered gunpowder is still too weak, and the direct lethality is simply not worth mentioning, granularization is an inevitable trend, at least before the birth of stable nitroglycerin, it is the best choice. In fact, the explosive power of granulated gunpowder is similar to that of powder gunpowder, but the instantaneous expansion force of powder gunpowder is uneven, the lethality of the conduction is weakened, and there is also a strong water absorption, which cannot be used when damp, and the storage and uniform conditions are extremely harsh.

Granulated gunpowder avoids these drawbacks, and the instantaneous expansion force is uniform in a limited space, and the explosion power is extremely strong and the lethality is great. Although granulated gunpowder has the disadvantage of slow burning speed powder gunpowder, as long as it is correctly matched, it is used in iron heavy firearms such as earth-shaking thunder and thunderbolt cannons, and the charge is evenly distributed, which can definitely exert great power, after all, the slow combustion speed is conducive to the durability of the explosion, and the killing of living forces is absolutely multiplied.

"The key is how to make gunpowder granular, not only in the mines, but also in warfare. Now there are a few questions, how to press the powder into a high-density powder? How to polish and screen after sieve? How can it be mass-produced? ”

Wang Xiu raised the key questions, he knew these necessary processes, but he was not able to solve them, he could only hope that Lin Shilang, foresight could not replace practice.

Lin Shilang, who was thin and had messy sideburns, looked at those bloodshot eyes, he was definitely a standard research freak, and Wang Xiu's words made him fall into deep thought.

"This can be solved slowly, at least produced first, to solve the problem of having and not having it. Now, the most important thing is how to increase the power of the thunderbolt cannon, whether it can solve the problem that the trebuchet is cumbersome and the thunderbolt cannon is too large. Wang Xiu tentatively proposed a way to solve the problem.

"Sir, this is not difficult to solve, the black medicine reduces the charge and rematches, it should be able to reduce the area, but it is not easy to throw it by hand. As for the miniaturization of the stone thrower, it is not my forte, and it is not easy to find the toughness tendons. "Lin Shilang is very confident and practical, yes or no, he is not mechanical.

Wang Xiu nodded, acknowledging Lin Shilang's modest attitude, and said, "There is a long way to go, and I believe you can achieve it from now on." ”

Zheng Yan and Zhang Ling looked fanatical, and even Lin Shilang's eyes flickered, full of enthusiasm.

"After all, the conditions here are simple and not very safe, and when this battle is over, you all go to Nanjing with me. Well, to go to Jiangning, I am going to set up a academy, you can set up a single qiē that you need, and then you will not be alone, but with all those who are interested, everyone will brainstorm and create a zào together. "Wang Xiu's idea is very realistic, the development of science and technology needs a leader, but only a few people must not, everyone needs to continue to communicate and brainstorm.

Sometimes, the progress of heavy technology is not a matter of thought, but rather an inadvertent inspiration gained from the experience of others.

The corners of Lu Yao's mouth twitched, with a bitter face, Wang Xiu took them away in a few words, didn't look at the hot eyes of the three, and couldn't wait to go, not to mention Lin Shilang, Fat Dun and the little blacksmith, but he was a good way to make money.
