Wen Tianxiang explained to Li Jun in a very sad tone: "The emperor doesn't know anything. This is Zhang Shijie who took the risk in person after setting fire to the Hui Hui cannons in Jiaoshan and sneaked into the Tartar camp to steal the drawings. We produced them according to the drawings. At that time, the emperor was still sleeping, so he didn't know about this."

Wen Tianxiang and his friends were in a complicated mood about Hui Hui cannons. It was this time that Hui cannons performed a historical tragedy. The Mongols could not catch them for several years when they attacked Xiangfan. Kublai Khan ordered Persia to transfer artillery experts to Dadu to build artillery. Ava Lao Ding and Yi Sima came to Dadu to build artillery. The first battle in Fancheng was almost razed Fancheng to the ground, and General Niu Fu died in battle. When fighting in Xiangyang, the first shot was knocked down Qiao Tower. Lu Wenhuan was scared and went out of the city to surrender, and handed over Xiangfan, the northern gateway to the Yuan Dynasty. It was the Mongolian army that set off from Xiangfan and began to advance towards Lin'an. At Jiaoshan, Hui cannons showed their power and destroyed the Southern Song navy, and Zhang Shijie lost 130,000 troops. Li Jun understood Wen Tianxiang and his friends.

Regarding how many months he was sleeping, Li Jun knew that he could not explain to Wen Tianxiang and the others, and said without saying anything, "How many weapons do you have? Take them out and show us."

"Abide by the order." Huang Yongshan received the order. Without waiting for his order, the military weapon supervisor took a few soldiers to get a bamboo tube. Huang Yongshan took it and said, "Master, this is our improved rocket. Install the fire in the bamboo tube, then install the rocket on, ignite the fuse, and the rocket will be shot out."

Li Jun, a native rocket of the Song Dynasty, had long heard of it, and took it with interest. After a closer look, it was just a bamboo tube with several more convenient launch designs. In the eyes of modern people, it was simply too rustic and not worth mentioning at all. However, Huang Yongshan, the ancient man, was very excited and talked endlessly about the advantages of this improved rocket.

Huang Yongshan looked proud, and Li Jun couldn't explain it, so he reluctantly became a good person and let him explain. When Huang Yongshan finished explaining, Li Jun said, "Cheer one and take a look."

Huang Yongshan received the order and handed the rocket to a soldier. The soldier took it to the bamboo tube and filled it with fire, then put the arrow on it, ignited the fuse, a ball of white smoke emanated, and a flame flew in the sky in an arc, shooting onto a tree a hundred and fifty steps away.

"Okay, okay!" Gundam, Wen Tianxiang and Zhao Qian applauded. Gundam said excitedly: "This is more than fifty steps further than the range we used. You kid will know how to hide your own privately and don't take it out for us to use."

"General Gao, you don't know that we have completed the improvement and have not had time to put it into production yet, so how many there are?" Huang Yongshan was afraid of grabbing the braid for Gundam, so he was busy explaining.

"What's the best? It's only better than fireworks, and it's not powerful at all. If you want to engage in actual combat, there's still a long road." Li Jun thought so in his heart, and had to pretend to be surprised, praised Huang Yongshan for a few words, and asked: "White smoke is so big, are you using the three-three-fitting fire yao?" The fire yao in the Song Dynasty was big, with a lot of residue, which was very difficult to use.

In Huang Yongshan's memory, Song Duzong only knew to look for flowers and willows all day long, and went to brothels to find women. He had no technical talent at all, so he didn't know the formula. At first hearing Li Jun talk about the formula, he was very surprised and said, "The emperor is wise. It's the third and third."

Li Jun understood his thoughts and said, "I have a recipe here. You can try it. Can it be used."

Li Jun's words were imperial edicts. Although Huang Yongshan did not believe it, he did not dare to obey it. He hurriedly took people to work. He was ready in a short while and directed his soldiers to fill it into the bamboo tube.

"It's not going to explode if you pretend so much." Li Jun thought to himself and said, "Don't do it too much, cut it half, yes, cut it a little bit, half of it. Tie it on the bamboo pole, don't use people to take it, go away." With Li Jun's guidance, the soldiers finally completed it and tied the rocket to the tree.

Only one-quarter of the original dose of medicine can have the power of the original one? Gundam would not believe that if Li Jun had not been focused on guiding the soldiers to operate, he would have asked a question. As soon as Li Jun finished speaking, Gundam immediately raised a question and said, "Your Majesty, I think it's better to pretend that way, or more."

What Gundam said, what Wen Tianxiang and others thought were all looking at Li Jun expectantly, hoping that he would change his decision.

"A little more, do you want to blow someone to death?" Li Jun thought so in his heart, but said, "Okay, light the fire. Run away after lit it, don't stand under the tree, be careful to blow it up."

The soldier ignited the fuse and ran away. Gundam curled his mouth and said disdainfully: "I really don't have any talent. What's there to be afraid of? Or isn't you a man? Touch your crotch, is there any fun..." His words interrupted a shocking sound, and he watched a ball of fire flash in surprise. He did not expect the rocket to cross the beautiful curve of the sky, but there was a sound of branches falling to the ground.

As Li Jun expected, it was really exploded. Not only did the arrows explode into several pieces, but it also broke a branch as thick as a wine glass. Not to mention Wen Tianxiang, Gao Da and Zhao Qian had never seen this power, even Huang Yongshan, who was dedicated to studying rockets, had never seen it. They were all so shocked that they stood foolishly.

After a long time, a cheer sounded and came from the mouths of everyone present.

"That's great, we're just here." Huang Yongshan said excitedly, and then said regretfully: "Where should we find something stronger than a bamboo tube?"

"This is easy." Li Jun was halfway through, and then interrupted Huang Yongshan: "Your Majesty, what are you good ways? Tell me quickly. You say, I will do it." He was anxious. Not only was he anxious, but Wen Tianxiang and the others were not very anxious. He stared at Li Jun and looked at him, hoping that Li Jun would give the answer immediately.

Li Jun understood them very much and said with a smile: "As a rocket, you don't need to build it. This thing is useless."

His words were so amazing. Even Gundam, who had always been very straight-hearted, was so surprised that he couldn't speak for a long time. Wen Tianxiang was stunned and said, "Master, is there a better way?"

Li Jun nodded and said, "I have a way to deal with the Mongolian cavalry."

Gundam immediately said, "Master, tell me quickly."
