Soldier Zhang found that Qin Shuai was very strange about the environment in which the old man lived.

He explained seriously: "These items, including money and weapons, were plundered by pirates. We brushed them over and then stored them here to be handed over. But in the past two years, because the alien warfare style is tight, the leader no longer has to give us money and weapons. These things are left for us to use temporarily. The old man just looked at the things he studied, machine guns and small cannon barrels, and looked at these supplies by the way. Sometimes we are really afraid of fire, but he is not afraid. As for the old man's living habits, this is the food. In terms of food, he passes food to him from the window every day, and he doesn't like breakfast every day. Noon and dinner are four dishes and one soup. Every meal is given to him, and every meal is delivered to the window on time according to his meal. Other aspects, such as when he needs convenience, there is a bathroom there, and the tube can directly lead to the bathroom downstairs, and it is washed clean, so he basically does not leave the house."

When they were about to enter the house, they suddenly heard the vague voice of the old man inside and asked who they were. Chief Zhang said it was him. He recognized Chief Zhang, so he came over and opened the door. Seeing that a strange young man was following him, he was displeased and wanted them to leave quickly.

But Chief Zhang said he was his friend, so he forced them to walk into the room. Qin Shuai saw some things covered with exquisite dining tablecloths, which should be machine guns, but they must be old-fashioned.

The old man: "My house has been around for some time, so don't laugh at me, especially young people like you. You probably have never seen such an old house. These things are old, so don't touch them, just look at them."

He immediately put on white gloves, then held a remote control, a slender mechanical arm like a robot, lifted up a dining tablecloth, straightened straight and polished machine gun immediately caught his eye.

Although it is an old style, the majesty is self-evident. Qin Shuai was stunned. I admire him very much.

Qin Shuai: "I really didn't expect that there are so many treasures near the bunker, Commander Zhang, you have, but can you just let the old man watch alone?"

When Qin Shuai said this, the old man and Chief Zhang were a little surprised. How could he say that these things were treasures? The scrap copper and rotten iron were almost the same, but it looked a little more beautiful than the scrap copper and rotten iron. However, the Qin Shuai said that the estimated price in his room should be worth millions. Chief Zhang couldn't believe it, and the old man felt that he had heard it wrong.

Qin Shuai said: "I have a general understanding of some firearm knowledge...it helps to understand the working principle of machine guns. You see, your small cannon barrel was created by imitating the structure of the cannon. Although it is very small, it has a complete function. It uses the high pressure pressure of a large amount of gas generated by the rapid combustion of the launching medicine to accelerate the bullet and shoot out of the cannon barrel. This is also the knowledge of ballistics. The cannon is the earliest and simplest application of this principle. The cannon is actually a metal tube, one end is closed and the other end is open. There is a small lead hole at the end. When loading the cannon, gunpowder must be poured in first, and then the cannon shells must be set. The gunpowder and the cannon are placed at the tail of the cannon, that is, the back of the cannon, and the cannon is the open space in the cannon. When preparing to fire the cannon, the lead wire must be passed through the lead hole and extend down to the gunpowder. Ignition of the lead wire can allow the cannon to fire. The flames burn along the lead wire and finally ignite the gunpowder."

"...After ignition, the gunpowder burns rapidly, producing a large amount of high-pressure gas. The hot gas will put a huge pressure on the shell near one end of the gunpowder, which far exceeds the pressure applied by the air to the other side, forming a pressure difference. The pressure difference accelerates the shell and pushes it out of the barrel. The initial handheld pistol is actually a mini gun - loading gunpowder, putting steel balls and ignitioning the leads. But this technology is eventually replaced by trigger-activated weapons, such as the flintlock of the flintlock and the firing cap of the fire cap of the fire cap."

Qin Shuai: "Your little cannon, although it's a bit old, it's just this thing, so I really don't recommend that you just put it on this house like this, you should use a safe."

The old man was fooled by Qin Shuai's words. He felt that the young man was a little mysterious, but there was a little reason. Chief Zhang believed it. However, they did not have such a large safe here, so they had to make one temporarily. They were not very good at designing it. However, Qin Shuai said that he could help, but the premise was that he could see what the two scholars were studying before. He was very interested.

Chief Soldier Zhang agreed, because the key was in the old man's hands and was from another room. They rarely went there and only went there once a week to clean it, and guarded it very tightly. And let Qin Shuai make a guarantee that if he saw any inspiration, he could not make the weapon 100% intact.

Qin Shuai: "The more you say this, the more I want to see it. Is it exactly?"

Chief Soldier Zhang: "That's only tomorrow during the day, because we did not have an electric light in that room. When the light is turned on, there will be explosions in the room, which is very terrible, so all the power is cut off."

Qin Shuai asked: "Doesn't the light of the mobile phone or the flashlight work?"

"Young man, that thing is like a wicked door. Anyway, it doesn't work with electronic products."

The old man said mysteriously. Qin Shuai guessed about eighty or ninety minutes, and this thing should be repelling electricity.

After a few people greeted each other, they visited the old man's things. Qin Shuai looked at them with love. The old man did not feel that it was very expensive. But these things seemed to be like his old comrades-in-arms, and were all eliminated from the battlefield. He looked like a comrade who could not be given up, watching every day.

But he didn't expect that Qin Shuai always said that they had great value, and the old man became more and more similar, so he hoped that Qin Shuai could visit him frequently. Soldier Zhang did not expect that Qin Shuai was so popular, and he was also very interested in Qin Shuai's valuation.

If these things are not valuable and rusted over time, it is better to auction them off. Chief Zhang had this idea, but Qin Shuai said that he would keep them here for the time being, but he hoped to make a safe. If Chief Zhang could find him the right materials, he would be happy to serve him.
