Powerful Song Dynasty

Chapter 515
Of course, he had a trump card and did not use it. The troops of Saili and Wang Bolong had not yet entered the battle, and a few new troops were thrown into the battlefield. It was very likely that they would defeat the Song army.

However, there was one thing he couldn't make up his mind, even if he invested a few troops too early, he could only defeat Qu Duan.However, the Jin army was fully deployed, and there was no reserve team anymore, so it could not effectively contain the reinforcements of the Song army. What he wanted was to complete the mobilization of troops, completely defeat the left wing of the Song army, and suppress the main force of Quduan between Luoshui and Gushui, forming a war. Mass annihilation.Song Jun appeared in Yishui, and he couldn't help cursing Qu Duan, this guy is too cunning, he has calculated the time, and he has taken advantage of the favorable terrain, leading him by the nose, his reinforcements will arrive sooner or later, Put him in a dilemma.

War is not a game, nor is it a treat to dinner. As an experienced commander, he understands very well the significance of the Song Army appearing behind the Jin Army at critical moments, especially when he is deploying troops. when weak.Even if the Song Army didn't seize the opportunity, as long as he cooperated with the reinforcements to defeat his left wing, even if he defeated the Song Army's left wing and cut off the connection between its main force and the camp, it would be of no avail, at most it could only be a draw.

"Lang Jun, the Silver Master Brother Lang Jun hastened to report, asking for reinforcements."

"Brother Yinshu, why didn't you invest all the horse troops?"

"Yishui found out that the Song people were active, and the silver master brother Langjun was afraid of the surprise soldiers from the Southern Dynasty, so he dared not use the remaining horse troops."

"Confused." Nian Han secretly cursed Brother Yinshu, the left wing was defeated, and the whole army had almost no chance of winning. Instead of shrinking back and forth, it is better to fight hard and buy more time for the whole army, so that the main force of the right wing can complete the fatal blow.

As for Wang Yuan's arrival on the battlefield, as long as the reserve team is not used, he can retreat calmly, and even launch a counterattack against Wang Yuan. It's a pity that Brother Yinshu is so smart and confused for a while, why can't he see through the situation.

"Go back and tell Brother Yinshu, don't have any reservations, you must turn the tide of the battle for me." Nianhan has already decided to abandon the left wing and concentrate on the right wing for a decisive battle. He must defeat Qu Duan before Wang Yuan arrives, at least he won't lose face too much.

It can be said that Wang Yuan's unintentional arrival caused great pressure on the Jin army. The Song army's formation is not so easy to break through. Even if the left wing of the Song army is defeated, they can still hold on for a long time. They can use Wang Yuan's reinforcements and be reborn again. A decisive battle.The strength of the Jin army on the battlefield was not enough to fight on both sides at the same time. As a result, Nianhan was very depressed.

In other words, Wang Xiu forgot to eat, also forgot the war in the west of Beijing, let alone the breakthrough of Wushu, he was completely immersed in Lin Silang's description.

Gunpowder, as the name suggests, is a combination of sulfur, saltpeter and charcoal, without any mystery. This era has mastered the art of making and continues to develop.

The development of gunpowder at this time is quite mature, and powdered black powder has a wide range of uses. It can use the burning power of gunpowder to launch powerful crossbow arrows.Rockets, fireballs and caltrops have been widely used, and heavy firearms such as thunderbolt cannons and thunderbolts have also appeared one after another. During the Tokyo Defense War, Li Gang used the thunderbolt cannon to fight against the Jin army. It was an explosive weapon of iron shell. !Light shock waves can shock people to death.

The court of the Song Dynasty also attached great importance to firearms, and unified the manufacture of firearms nationwide. The ten major institutes of the military supervision department each had a share of gunpowder and firearms. The manufacturing institutes of each military state also produced gunpowder, which was quite popular.

Unfortunately, in Wang Xiu's eyes, the power of powdered gunpowder is still too weak, and its direct lethality is simply not worth mentioning. Granulation 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 powdered gunpowder, but the instantaneous expansion of powdered gunpowder is uneven, resulting in weakened lethality. Moreover, it is also extremely water-absorbent, so it cannot be used when it is wet, and the storage and uniform velocity conditions are extremely harsh.

Granularized gunpowder avoids these disadvantages, and has a uniform instantaneous expansion force in a limited space, with extremely strong explosive power and great lethality.Although granulated gunpowder has the disadvantage of burning slower than powdered gunpowder, as long as the proportion is correct, it can be used on heavy iron firearms such as Zhentianlei and Thunderbolt Cannon. The charge is evenly distributed, and it can definitely exert great power. After all, the burning speed Slow, which is conducive to the persistence of the explosion, and the killing of the living force will definitely increase exponentially.

"The key is how to granulate the gunpowder, so that it can be used not only in mines, but also in battle. Now there are several problems, how to press the powder into a high-density powder cake? How to sieve and then polish and sieve? Production?"

Wang Xiu raised key issues. He knew these necessary processes, but he was unable to solve them. He could only hope for Lin Silang, foresight cannot replace practice.

Lin Silang, who is skinny and has disheveled hair, looked at those bloodshot eyes, he is definitely a standard research madman, 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 or not. 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 heavy and the iron stone of the Thunderbolt Cannon is too big. Wouldn't it be better to hit the enemy head-on if the officials could throw it with their hands?" Wang Xiu tentatively suggested the direction to solve the problem.

"Sir, this is not difficult to solve. The black medicine reduces the charge and re-proportioning, which should reduce the area, but it is not easy to throw it by hand. As for the miniaturization of the trebuchet, I am not good at it. I just look for tough tendons." It’s not easy.” Lin Shilang is very confident and down-to-earth, he is not a mechanic.

Wang Xiu nodded, approving Lin Silang's modest attitude, and said sternly: "There is a long way to go, everything starts now, and I believe you can achieve it."

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

"After all, the conditions here are crude and not very safe. After this battle is over, all of you will go to Nanjing with me. Well, I will go to Jiangning. I am going to set up an academy, and I can set up everything you need alone. By then, will you all go to Nanjing? One person, but together with all interested people, everyone brainstorms and creates together.” Wang Xiu’s idea is very realistic. The development of science and technology requires leaders, but it is absolutely impossible to rely on only a few people. Everyone needs to constantly communicate and brainstorm .

Sometimes, major technological advances are not due to hard thinking, but inadvertently inspired by summarizing the experience of others.

The corners of Lu Yao's mouth twitched violently, with a bitter face, Wang Xiu blinded them away with a few words, and didn't look at the hot eyes of the three, wishing to leave immediately, not to mention Lin Silang, Fatty and the little blacksmith, but he earned A good handle on money.
