The control of the trebuchet is not difficult, the difficult thing is that the stones that are driven out must have a certain accuracy, not too far and not too close, and it is best to fall all into the valley and become an effective striking force. To master this skill, it takes several operations to basically grasp the laws of machinery.

In order to achieve the desired combat effectiveness, the soldiers had sealed off the valley, and the people who came and went, mainly those who had taken refuge from the south, were forced to climb the mountains and make a detour.

The cavalry had only been formed for a few days, and it was not possible to engage the enemy head-on with the tip of the needle. But the horses were equipped with saddles and stirrups, which multiplied their power, making it possible for the knights to quickly improve their riding skills.

The configuration of the spear made the cavalry bid farewell to the era of short weapons, and it was a leap forward for the cavalry. The newly formed cavalry in Taiping Village had combat effectiveness beyond the imagination of the enemy, which greatly increased the confidence of all the soldiers.

The general who commanded the cavalry turned out to be Li Yi, the most eye-catching in the first battle, and his powerful charge shocked everyone who witnessed it. Li Yi made an action on the horse, which was impossible for the brave and good Xianbei people to complete, leaving an indelible impression on every soldier who experienced that hard battle. Li Yi has undoubtedly become the spokesperson of Taiping Village, as long as the first battle is mentioned, no one does not praise this brave and resolute hero.

The superposition of several favorable factors has produced an amazing effect, and the two hundred tiger and wolf soldiers are already eager to try, and have made an oath to use the steel gun in their hands to teach the enemy a lesson!

Li Yi shouldered a dual task, and the cavalry he led remained in Taiping Village. Although it was determined that the Hu were marching from the north, they were anticipating that in case of a loss, the enemy army would come from the south, and this team would play the role of a decoy to lure the enemy into the valley.

Learning from the lesson of the last time, Song Zhi conducted several more drills, some of which were not even announced, the purpose was to let the people form a habit and enter the underground bunker smoothly when the crisis came.

This time, the alarm was issued, but the personnel were unusually safe, and they acted in an orderly manner under the command of the heads of the sub-points. The number of people was several times larger, and the time to enter the tunnel was shorter than the first attack.

Entering the tunnel is just in case, in Li Yi's opinion, this time is a superfluous move, because this time the preparation is too sufficient, and the trap has been set up, just waiting for the prey to drill in!

The net has been cast, but there is still a lack of a net port, which is also due to the strategy of blocking at both ends as a precautionary measure. Now that the goal has been determined, this closing is the key to whether the campaign can be perfect.

"Brothers, it's time for us to behave!" Li Yi was full of confidence, his voice was loud, without the slightest mixture.

"Taiping cavalry, every battle will be won!" With a high-pitched shout, the soldier gave the Lord a beautiful response.

"Let's go!" With Li Yi's order, the two hundred knights shouted: "Drive!" Eight hundred iron hooves roared, and with the trembling earth, they handed over an answer sheet to the people below.

"Dismount and dig a pit!" In just a few moments, the cavalry team entered the mouth of the Broken Soul Valley, and Li Yi used four words to make a judgment in advance against the attacking Xianbei army.

The Valley of Broken Souls was originally a nameless valley, and it was Zhang Ying's temporary idea, according to the name of the Hu people in the Valley of Broken Souls this time. However, this name invisibly boosted the fighting spirit of the soldiers participating in the war. The soldiers encouraged each other, and then used the word "broken soul" to strengthen their own minds and suppress the enemy's morale.

Two hundred and two lang got off the war horse, the shovel and pickaxe waved like flying, digging and transporting, ping pong, jingling. After a period of busyness, a large pit across the mouth of the valley and about one zhang wide separated the Valley of Broken Souls and the Taipingchuan into two worlds.

"A deep ditch one zhang wide, I'm afraid it won't stop the Xianbei cavalry!" Seeing Li Yi nodding with satisfaction, Li Heng reminded with a worried face.

"Of course, this ditch can't stop the cavalry, a good man can jump over without effort, but let's do something on the top of the ditch, so that Hu Ren can't see the flaws in it, can he still pass?" Li Yi's eyes are radiating light!

"That's right! How did I not think of this layer? Li Heng shook his head.

"You're not in a sharp turn!" Li Yi smiled and waved his hand: "Time waits for no one, let the brothers do it!" ”

"Brothers, find some thatch and put a lid on the pit!" Zhang Sheng shouted first.

Li Heng and Zhang Sheng are two newly promoted cavalry commanders, who can be promoted one step ahead of others, and enter the elite troops that have attracted the attention of thousands of people, which makes the two of them feel unsurpassed glory. Especially Zhang Sheng, if it was all based on his military exploits, he would be indistinguishable from the rest of the brothers, but he had superb riding skills and had the prerequisites for entering the cavalry. And this time he was lucky, so he cherished the hard-won opportunity even more.

Being able to enter the cavalry and become the advance party to stop the enemy soldiers made the blood of the brothers run high. As Zhang Sheng's shout rang out, the brothers were busy again, sprinkling limestone powder in the ditch. These quicklime powder is the fruit of the labor of more than 1,000 people, who are not afraid of hard work, go into the mountains to quarry, and transport them to the village to smash into powder.

The main component of limestone is calcium carbonate, and the rest of the impurities can only be collectively referred to as stone at the current level of science and technology. Calcium carbonate is a salt that is insoluble in water and cannot be effectively killed, so it must go through a process and be burned with a fierce fire.

Thousands of hammers were carved out of the deep mountains, and the fire burned as if it were idle. I am not afraid of broken bones, and I want to leave my innocence in the world. This poem is written by Yu Qian, a master of the Ming Dynasty, and it uses the situation of riddles to explain some of the characteristics of quicklime and the refining method.

The firewood was high in flames, and with the help of the common people, the magic weapon needed to break the enemy was quickly fired, providing a strong logistical support for resisting the invasion of the Xianbei people.

An invisible lid made the giant ditch disappear without a trace. In order to make it more realistic, the people sprinkled some mulch and fallen leaves on it to make it blend in with the surrounding scenery.

"It's coming! Hide, everyone! "As soon as they had done everything, they saw smoke and dust rise from the north side of the valley and spread rapidly to the south.

Li Yi stared at the suspended ground with his eyes, as if he saw that the huge pit below was full of Xianbei prisoners, and the soldiers were escorting the prisoners of war with the joy of the victors, and sent them back to the village in groups.

Iron hooves rumble, smoke and dust fly. The soldiers' hearts trembled violently, and the pace of pacing was almost twice as fast as usual. Seeing that the warrior beside him was pale, his teeth were clenched and his lower lip was biting, and blood was already oozing out. Li Yi smiled and said, "Don't your lips hurt?" ”

This person's name is Mo Hai, and he could have been promoted to captain, but in order to come to the cavalry, he took the initiative to give up the former. Mo Hai's nerves were too tense, and Li Yi's kind reminder made him realize that his lips had been bitten.

"Hu Ren!" Li Heng next to him snorted softly.

"Calm down, wait for the enemy to fall behind, let's take advantage of the chaos to rush over!" Li Yi squinted his eyes, his expression calm.

Li Heng nodded, he gathered his mind, stared ahead, and held the spear tightly in his right hand, revealing a look of being ready to attack.
