What did I say to me?" I glared at Liu Shuang and held her hand: Don't move, don't you understand? You came here to help, but I begged your master for a long time before he agreed to ask you to help some advice. But it is not for you to come to such places where you are in danger at any time. If something happens to you, how should I explain to your master and how should I explain to your brother?" I raised my face and stared at her and said seriously. Liu Shuang's original surprise gradually dissipated, but red clouds appeared on her face, as if she was shy, and she was actually dodging my eyes. Hum? What is this girl doing?

However, seeing that she was taught by me and did not retort the ground, I let her go first. After a while, the flush on Liushuang's face gradually dissipated. She slowly pulled her hand from my hand and said thank you softly, Fang Zheng said, "Young Master, I have a way to make these gunpowder more powerful. I am now trying to play these masters."

"Hmm?" I was stunned when I heard Liu Shuang's words. Could it be that Liu Shuang knew how to make nitrified glycerin? But nitrified glycerin had nothing to do with these explosives she was fiddling with?

"I have tried many times with these masters. The burning of gunpowder is always insufficient. I have tried it myself many times, and then I found that the more round the gunpowder particles are, the more moderate the size of the particles, the more sufficient it will be. In other words, the more powerful it will be." When Liu Shuang talked about serious matters, the brilliance in her eyes was like a rainbow that also smeared the sky, which was amazingly bright.

Liushuang picked up a small piece of ground gunpowder smaller than rice grains from the wooden barrel filled with gunpowder, and handed it to my eyes: "The gunpowder particles of this size are the most suitable. Then, the screened gunpowder particles of this size are placed in a large wooden barrel, pressed it on this rack, and let it roll continuously. It takes about a day to make them have no edges and corners. This way, it can be more powerful and can almost completely burn."

"Is that?" When I heard Liu Shuang's words, I couldn't help but feel excited. I looked at the black gunpowder particles in the palm of my hand, and then looked at Liu Shuang who was still excited when standing in front of me. "Thank you!" I thanked Liu Shuang very sincerely. Liu Shuang seemed to have not reacted, or had not heard it clearly, and looked at me with questions in her beautiful eyes.

"I mean, thank you. This is very important to our Wuhan Institute and our soldiers in the Tang Dynasty." I repeated the words just now again. Liu Shuang looked away with a little embarrassedly, but I could tell from her expression that she must be in a happy mood.

"In two days, we will use this granular gunpowder to re-create the new ground grenade. At that time, we can test the power of this gunpowder." I watched the barrel be screened and placed on a wooden stand in a newly built house on the bank of the river. The hydraulic power will allow the barrel to roll the ground gunpowder at the same speed, and smiled at the edge of the ground.

"Can I come and have a look?" Liu Shuang nodded and continued as soon as she asked. "Of course." I turned around and looked at Liu Shuang and chuckled. Does this girl know what politeness is in front of me?

Liushuang was stunned and glanced back at me. She realized what she said. Her pretty face turned slightly red: "You don't need to agree, I'm going to come too!" Leaving this sentence, Liushuang walked quickly towards Lai Lu, but it gave me the feeling that she was more like running away.

Zhong Hua smiled strangely, with his two front teeth exposed outside his lips, and his face was very disgusting. I glared at Zhong Hua: "How are you smiling? What's ridiculous? Why don't you go to work on your affairs? Remember. Two days later, not only me, but your Majesty will come to inspect, so why don't you prepare to go quickly? If something goes wrong then, be careful I will take you to take the blame!"

"Ah?!" Zhong Hua was shocked by my naked threat. He quickly bowed to me and hurriedly ran to work hard.

Two days later, Uncle Li and Li Jing, Li Ji, Uncle Cheng, Su Dingfang, Li Daozong, Yan Lide and other senior Tang Dynasty military generals and heads of the Ministry of Works quietly appeared at the Wuyan Institute's shooting range under the protection of a group of Qianniu Imperial Guards led by the Yuchi Twins. This is an unknown valley surrounded by mountains on three sides, with only one road entering, and the entrance is the side gate of the Wuyan Institute.

I was wearing mail inside, with a heavy armor on the outside, and a pure steel phoenix-winged helmet on my head. I was shining with my body, and I was shining with my eyes on Zhong Hua in an official robe on the side. Zhong Hua narrowed his eyes and said to me in confusion: "Sir, why are you wearing this? We are doing artillery exercises. Not combat exercises."

I patted the armor on my body and smiled at Zhong Hua: As a general, I should wear this set to welcome His Majesty. I talk nonsense. In fact, I like this set of metal armor more. I am a little shy about what I should do to defend against. I am embarrassed to tell Zhong Hua.

Zhong Hua shook his head helplessly. He didn't understand my inner thoughts, which was normal. However, if I didn't wear it like this today, I would feel insecure when I was doing artillery bombing tests for a while.

Uncle Li saw me fully armed and couldn't help laughing: "Son-in-law. Why are you willing to wear this outfit to welcome us today? Is it because you are afraid that your father-in-law Cheng will slap your shoulders?" Uncle Li's ridicule made me embarrassed. It seems that Uncle Li is still very revengeful.

Uncle didn't feel any shame at all, but instead came to me and said proudly: "Don't be afraid of the virtuous young man. Today I came here for official business, not to come here to break your little arms and legs. However, when you wear this, you have some generals' aura. Well, you are a good person, you deserve to be the son-in-law of the Cheng family. Let's lead the way. I have to see what kind of tricks you can do when you make firecrackers in the ground. Hahaha..."

Uncle Li saw that the sarcasm had no effect on Uncle Cheng, and he couldn't help but curse him angrily: "Old man!" Then he led everyone to the shooting range of the Wuhan Institute of Technology.

Uncle Li and these senior military generals were surrounding the thick long metal hollow cylinders to study the weapons and equipment they had never seen before. Uncle Cheng had a very experienced trick, took his eyes to the center of the hollow gun barrel, glanced, nodded, "This thing is thicker than the old Cheng family's smoke pipe. A young son-in-law, are you trying to use this thing to load firecrackers and bomb people?"

－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－-

I was watching the fun next to me and heard Uncle Cheng’s problem and almost laughed out loud. However, I can’t make fun of this old hooligan in public, otherwise the fate would be very desolate.

I walked forward: "My father-in-law, this thing is not only used to bomb people's land, but its power is so great that it can also collapse the city wall. Compared with the past used to open stone medicine bags, people do not need to stuff the medicine bags under the city. As long as we stand in this place, we can attack enemies or city walls one or two miles." I carefully explained this new type of weapon: mortar to Uncle Cheng and a group of senior generals. It will be a new type of weapon with a cross-age significance. Its appearance was five or six hundred years earlier than the use of ground-ram muskets in the Song Dynasty, and more than a thousand years earlier than the later mortars. Its birth will sound the horn of the land coming to the firearm era.

"You mean that this object can be used to collapse the city wall? Without the need for people to send the gunpowder bag to the foot of the city wall in advance?" Uncle Li Jing asked his own question first.

I nodded and smiled, "That's right." Su Dingfang squeezed up to look at the gun barrel, and asked curiously, "Why does the inside and outside of this tube seem to be different in color."

"Oh, this gun barrel is a trial type gun barrel in the latest test area. The ground material used inside is steel, and the ground wrapped on the outside is copper. In this way, the hardness of steel and the toughness of copper ground are combined to improve the durability of the gun barrel. However, there are not many new gun barrels." I explained patiently that there are not many new alloy gun barrels. In this artillery performance, there are only five gunmen using this gun barrel. The other places use copper barrels.

These were all the ground gun barrels that the craftsmen of the Wuyan Institute worked hard to overcome various difficulties before casting the ground gun barrel as a whole. These gun barrels were not thick. At least I knew how thin the wall of the gasoline barrel was. The wall tubes we now cast were at least tens of times the thickness of the wall tubes that were dozens of times that of the gasoline barrel, and about half an inch thick. Each gun barrel was about 1.5 meters long and weighed between 250 kilograms and 300 kilograms. At least it can ensure that each gun barrel can be reused hundreds of times?
