"Wei Jiu, look!"

In Wei Jiu's room, Gong Shu Datuo took out a drawing in his arms and spread it carefully on the table. He pointed at the drawing seriously. Wei Jiu looked at the mess on the drawing and asked in confusion as he looked at the messy things drawn on the drawings.

"What's this? You came to the Western Regions to show me this?"

"Listen to me."

Gongshu Datuo was a little anxious and pointed to the drawings to organize the language. Wei Jiu was not in a hurry. He put on his clothes and gave himself a cup of hot tea. It may be because of his habits. Whether it is spring, summer, autumn and winter, Wei Jiu drank hot tea, and stood by Gongshu Datuo lightly without urging him.

After a while, Gongshu Datu seemed to have thought about it and spoke.

"This is the drawing! I did an experiment in Chang'an. Didn't we fail to make a steam engine before? There was an iron box left. Once I threw the drought thunder in without any trouble. At that time, I thought that after the iron box had a finger, it should be fine, and then I suffered a big loss."

While speaking, Yuchi Da lifted up his clothes, and there was a trace of a knife edge and needle on the left side of his lower abdomen. Wei Jiu frowned and said.

"The iron box flew up? Or were you so scared that you hit? The knife is quite sharp."

Gongshu Datuo kept shaking his head.

"No, no! The box didn't fly, and I didn't run either. It was a screw. There was a screw on it. It was a loose screw and flew out along the impact of the drought thunder. I just felt a sharp pain at that time, and I was bleeding from the lower abdomen. I didn't think too much about it. It was not until Princess Changle and Wei Si Gang were bandaged to know that there was a screw here. I didn't see the screw flying over at that time. It was too fast, and how powerful can the screws be?"

Wei Jiu still didn't understand what Yuchi Datuo meant and asked frowned.

"I've come to ask me for credit? You can just find Qu Qingxuan and the others. Why are you going to travel far to the Western Regions? Is it a waste of my life?"

"No! I'm short of money or what do I lack now? The reputation of a public loser is not something I made of Yuchi Datuo. I mean, the strength of the thunder explosion in the dry days can shoot the screws out. If screws are installed on one side of the iron box, then when the thunder explosion in the dry days is exploded, how much lethal will the screws fly out."

Why?

Wei Jiu understood, put down the teacup and took the drawings and looked at them carefully, and asked softly.

"You mean to use drought thunder to replace the bow string and the spring of the arrow cassette to increase the firing force, right? But have you ever thought about the shortcomings?"

Gongshu Datuo nodded.

"I know there must be disadvantages. The screws are too small and the installation speed is not as fast as the arrow box, and the iron box is heavy and has difficulty moving."

Wei Jiu smiled when he heard this.

"What you said is also the safety issue. If the box is not hard enough, it will cause damage to yourself. And once it is used for a long time, the lifespan of the box will not be too long on a high-intensity battlefield. It is already very good to be able to find this, but it is still a little short of time. Continue to study!"

Wei Jiu was about to leave after he finished speaking. He had no time to study these things with Yuchi Datuo for the time being. Changing defense and Lu Dongzan was enough for him to have a headache. He wasted an afternoon. He could not continue to waste time, but Yuchi Datuo stopped him and looked at Wei Jiu with a serious expression.

"Did you know that the thunder in the dry days will replace bowstrings and springs again? Wei Jiu, you must know a lot of things, but you just don't say it, tell me! Tell me what you know about this, I swear! I will never tell anyone, even if it is developed, I will destroy it."

Gongshu Datuo was very sincere, or he was obsessed with the research institute and was sickly, but Wei Jiu still shook his head.

Plop!

Yuchi Datuo knelt down on his knees, and Wei Jiu sighed when he saw this.

"The more you know, the more dangerous it is to you, are you sure you want to know?"

Gongshu Datu nodded vigorously. Wei Jiu knew that if he didn't tell him, this guy would definitely not give up. He pulled Yuchi Datu and came to the table, took a pen and drew a simple model on the drawing, and said softly.

"Your idea is right, and it surpasses many people of the same era. Its knowledge limits your imagination and hands-on ability. Look at this, the size of a finger, you can design it into two pieces. The front is sharp and sharp, and the back is filled with gunpowder. The first half can be shot out under the force of the gunpowder explosion, which reduces a lot of danger and is easy to carry. I named this thing Bullet."

Gongshu Datuo was very smart. He looked at the drawings and understood after listening to Wei Jiu's explanation, but he also discovered another problem.

"Wei Jiu, according to what you said, it is indeed feasible, and it is also very convenient to carry. Your design behind is sealed, and the gunpowder inside also needs to be very dense. Of course, these are not problems. The question is how do you ignite the gunpowder?"

"Ouch!"

Wei Jiu smiled and said softly.

"This requires another tool. The bottom fire should be designed at the back of the bullet. When the bottom fire is hit by metal, it will light the gunpowder in the bullet, thereby producing an explosion effect and shooting the bullet. The design of this tool is more cumbersome. It cannot be too heavy, but it cannot be too light, and the operation cannot be too complicated. I used to have a model at home, but it was broken by Wei Buyuan. I was too lazy to do it afterwards. Otherwise, you can study it yourself in the Western Regions? I can help you in my spare time, but there are not many drought thunders here, so you need to make it yourself. How can you?"

When Wei Jiu remembered this, he couldn't help but get angry. He used Liuli to make an AWM model. Wei Jiu often touched and wiped this model. It was also this model that reminded him that he was a time traveler. Unfortunately, Wei Buyuan was very rebellious at that time. He would try every means to break the things Wei Jiu liked.

At that time, Wei Buyuan was beaten. After all, his son was more important than the model. He has been busy since then and has not been doing it. But Gongshu Datuo was restless and looked at Wei Jiu with his eyes twitching.

"Broken? Such a treasure is broken? Wei Jiu, if this is my son, I will definitely clean up the portal."

Bang!

Wei Jiu slapped Gongshu Datuo on the shoulder and cursed.

"Get out of here, that's my own son, just a broken model. Will you make drought thunder? Now that the military weapon surveillance is constantly improving, I won't even do it."

Gongshu Datuo nodded vigorously while covering his shoulders.

"That thing is simple. Except for the people in the medical department, it will almost do it. It is not as complicated as you imagined. If you want me to do it for you tomorrow, but Wei Jiu, can you draw a model for me? Don't hide it. If you tell me this, I will definitely not ask you in the future."

Wei Jiu cursed.

"You won't ask me, but Li Tai will definitely do it. I will be annoyed by you two at that time. Draw and draw! If you kneel down, I will kill you. Remember! You can only make one, at most two! And you can't let Li Chengqian know, nor let him touch it. Do you understand?"

In the end, in Gongshu Datuo's oath that he would never give in his life, Wei Jiu made a general approximation for him. Wei Jiu didn't know the specific structure of AWM. He only knew some simple truths, not just these. It can be said that this has been like this for so many years. Wei Jiu talked about all the things, and let them study the rest themselves. If they were researched, they would use it. If they couldn't study it, they would be overturned.

The steam engine is an example, and it has not been made yet.
