In the Tang Dynasty, when generals heard "cannons", most of them thought it was "cannons". Therefore, the trenchers in the time were also called "cannons". Therefore, everyone was disappointed when they heard Li You's words. The trenchers they used under the city today were the most advanced and powerful trenchers that the Tang Dynasty could transport here. They were even bigger and had a longer range. They were not without trenchers, but they were too huge to transport them to the Western Regions. Gao Xianzhi and others thought that Li You had just made a little improvement in the existing trenchers. After a moment of thinking, they felt that the "thunder cannon" he mentioned did not play much role, so they were slightly disappointed.

"Oh? What kind of cannon is it? It's actually called Pili?" Cen Shen was a scholar after all, and he was much more sensitive to writing than these generals, and soon discovered the key.

"As soon as this cannon was released, the sound was like thunderbolt, so it was called 'thunderbolt'. You can follow me to the back camp to see it." The thunderbolt is actually a projectile that can explode. During the Jingkang period, the Jin people besieged Bianjing. When Li Gang was defending the city, he used the thunderbolt to repel the Jin soldiers. The notes of literati at that time recorded that "the thunderbolt cannon was fired at night to attack the thieves, and the army exclaimed."

As a later generation, how could he not know the power of gunpowder weapons? In "Ji Xiao New Book", Qi Jiguang clearly records the formula and production methods of gunpowder: one liang of tin, one qian of sulfur, one qian of willow charcoal, eight qian of willow charcoal, a total of 40 liang, five liang and six qian of willow charcoal, seven liang and two qian of willow charcoal, two jingles of water, and pound it to the finest. Secret method: first grind each of the tiny tin and yellow charcoal into powder, mix it into one place according to the number, use two bowls of water to pound it in the wood slag, and pound it into a wooden slag. Those who do not use stone wool may have fire. Each slag can be pounded tens of thousands of pestles. If you pound it dry, add a bowl of water and then pound it, and use a fine amount. Pound half dry, take it to the sun and break it into large pieces of beans. The beauty of this medicine is that only tens of thousands of pestles are pounded.

From here, we can see that Qi Jiguang made more advanced granular gunpowder. On the way from Anxi to Suye City, Li You found several skilled and taciturn craftsmen, promised various benefits, and persuaded them to make this gunpowder and collected saltpeter, sulfur and willow charcoal all the way. The gunpowder accumulated by now is quite considerable, and now it is time to finally make the gunpowder weapons on the stage of history ahead of schedule.

"There is no joke in the army. If the thunderbolt cannon offered by Li Duwei is of little use for siege, why don't you delay the time of Lord Dugu?" For some reason, when he heard the three words "thunderbolt cannon", Tushi Sanlan felt nervous and hurriedly advised.

"Oh, I forgot that Lord Ye Hu was injured in fighting for my Tang Dynasty today. Since that's the case, Lord Ye Hu would better go back and rest earlier." Li You glanced at the Taotao and said with a smile. After saying that, he curled his smile and bowed to Gao Xianzhi, "Mr. Dugu, I will guarantee this thing to be of great use, otherwise I would be willing to engage in military law."

Seeing that he was so solemn, Gao Xianzhi couldn't help but feel at ease. In addition, the military discussion today did not discuss any good solutions, so he stood up and said, "Since Li Duwei is so sure, let's go to the back camp! Duan Xiushi was stationed in the camp, guarding against Dashi's sneak attack at night, and plotting to assassinate the ransom Ye Hu and go to rest. Li Siye, Cen Shen, and Tian Zhen are with me!" After that, he turned his eyes to Bian Lingcheng, "I don't know the military supervisor?" He was not good at giving orders directly to this eunuch.

"Haha, since we have such a powerful tool, we have to go and take a look no matter what!" Bian Lingcheng's sharp voice sounded again, and everyone got goosebumps.

He wanted to persuade Gao Xianzhi not to obey Li You, but Li You directly bet on his official position, leaving Gao Xianzhi speechless, and he also cut off his chance to see the truth, which made him really depressed, but now it is not so easy to take back his previous words, so he had to watch them leave depressedly.

Everyone went out of the camp to get on the horse, and then Yue Se ran all the way to the back camp. Ah Silanda Khan was also coaxed back to the camp by Li You using the excuse. Only Gao Xianzhi and several Tang generals were left. About half an hour later, everyone arrived at a camp that was closely guarded. Here, there were high on all sides and low in the middle, just in the bottom of a valley, and Pan Feng was the one who led the army to guard.

"What a man, but I don't expect there are such powerful generals in Li Duwei's army." Seeing Pan Feng, Gao Xianzhi couldn't help but praise him, becoming more confident that Li You had an extraordinary background, otherwise would there be such a great general?

After verifying the identity, everyone came to the camp and saw a smaller trencher on the open space in the camp. Several round stone bullets polished by stonemasons were piled next to the trencher. The direction of the trencher was aimed at was empty. Judging from the position of its placement, the thrown stone bullet should have fallen deep in the valley.

It seems to be no different from the trencher under the city, and it is even smaller than the model. What is the use of such a thing? Gao Xianzhi and others were quite confused, but they remained silent on their faces, "Master Li, can you tell me what is the speciality of this thunderbolt cannon?"

"When you launch it later, please cover your ears to avoid damage to your hearing." After saying that, Li You saw that everyone's horses were tied up and issued an order to test the shooting.

Then a group of craftsmen became busy around the trencher, put a stone bullet on the throwing bucket, took a torch and lit the fuse of the stone bullet, and then the trencher suddenly threw the stone bullet out and flew far into the depths of the night.

How do you know how powerful this stone bomb is? Why should you ignite the fire before launching? Gao Xianzhi and others were confused for a while and forgot to cover their ears.

"Boom!" Just as he was about to speak, a huge ball of fire suddenly burst out from the front, followed by a deafening loud noise, which made everyone's ears buzz. The horses beside him made a terrifying neigh. If they had not been tied up just now, they would have scattered and fled.

After the thunderous sound, another squirm of flint hits. After a long time, the buzzing sound in everyone's mind gradually stopped. Gao Xianzhi shouted in a voice that was several times larger than usual, "It's really like a thunderbolt!"

"This object was to cut the stone bullet into the air, stuffed with gunpowder in the middle, which made people scary. Stone bullet fragments could also be used to kill the enemy." Then Li You ordered people to fire three stone bullets in a row, then took the torch and led everyone to the place where the stone bullets had just flew past.

When everyone was shocked when they saw the fragments of stone bombs flying around and the branches that were blown up everywhere. After a little silence, Gao Xianzhi asked, "How many such thunderbolt bombs are there in the camp now?"

“There are hundreds!”

"Okay, I'll leave it to Li Duwei tomorrow!" Gao Xianzhi shouted, let's see how these big cannibals deal with this thunderbolt cannon. (To be continued.)
