Chapter 73 Learning English

In the next few days, Section Chief Hou led Liu Hai to touch the milling machine, grinder, and boring machine, and also found some unused knives, and taught Liu Hai to sharpen them.

Li Dali ate Liu Hai's fish, and became more and more attentive. He came to help Liu Hai with his lessons every night. Apprentices are good.

Liu Hai often went to the scrapyard for a walk, and finally on Saturday, he found a can, but it was not a gas can, but an oxygen bottle.

What Liu Hai doesn't know is that our gas tanks and oxygen tanks also started from picking up rags. They seemed to be picked up by foreign mountaineering teams. The oxygen bottles and fuel tanks carried by the mountaineering teams were picked up by us. , and then it started.

At this time, there were gas tanks and gas stations in Kyoto, but the proportion was very low.

This oxygen bottle is sunken, I don’t know why, even if it is repaired, it can’t be used, because the metal is tired after the sunken repair, I took out a tape measure and looked at it, the diameter is 15.9, and the height is 65.
Liu Hai didn't know if the specifications behind the oxygen cylinder had changed. After all, so many years had passed.

"Take this down for now." Liu Hai felt that this was fine.

Taking the oxygen bottle back to the motorcycle factory, Section Chief Hou looked at Liu Hai holding this and asked, "What is Xiao Liu doing?"

"Chief Hou, I have an idea here..."

"I think the combination of mortars and heartless cannons seems to be causing trouble?" Liu Hai made some gestures and then finished.

Section Chief Hou got a lawsuit on his head, and asked, "This thing shouldn't be accurate, right? Oxygen cylinders are also very expensive?"

"Chief Hou, it's so powerful. Look at this thing. Is it the same size as a heavy artillery shell? It may not be useful in field battles, but what about street fighting?" Liu Hai gestured to Chief Hou with the oxygen bottle.

"It's really..." Section Chief Hou looked at the oxygen bottle at this time and compared it with the heavy artillery shells he saw.

"Can you elaborate more?" Section Chief Hou continued.

"No, I just have this idea. There are still many things I don't understand. Add a mortar tail at the back, but I don't know what the size of the tail is. Last time I asked Teacher Zhu from the University of Technology for advice. I will do it again this Sunday. Ask." Liu Hai shook his head and said.

"Well, tell me if you need it." Chief Hou didn't think it was that powerful. After all, we also have artillery now, but it can't dampen Liu Hai's enthusiasm. It's okay to try it.

"Thank you, Brother Hou." Liu Hai breathed a sigh of relief.

On Sunday, Liu Hai continued to come to the literacy class. Teacher Zhu was also very happy when he looked at Liu Hai's homework, because Liu Hai was also studying during working hours, and his learning progress was also very fast.

Xiaolin is still sitting next to Liu Hai, the little girl has two pigtails tied up, and she does her homework in class, and she goes out to play with Teacher Zhu after class, and let Liu Hai be with her, but Liu Hai doesn't go out easily to do research It takes a few hours to sit and get used to it.

At noon, Teacher Zhu insisted that Liu Hai go to dinner together. Teacher Zhu drove Xiaolin, with Liu Hai behind, to the University of Technology, which was about ten kilometers away.

"Master's Wife." When they arrived at Teacher Zhu's house, Master's Wife hurriedly started cooking when she saw people coming, and Liu Hai said hello.

"Xiao Hai is here, sit down quickly." The teacher's wife greeted Liu Hai with a smile.

"Good." Liu Hai nodded, and found a place to sit down.

At noon, I ate rice, fried meat with fungus, egg and vegetable soup, and a roast tofu.

"Xiao Hai, eating vegetables, is growing up."

"Thank you, Master, I'll do it myself."

"Teacher, Mistress, if you want to buy meat in the future, you can come to me. Dahongmen Meat Factory is not far from here." Liu Hai said after eating.

Just as Mr. Zhu was about to refuse, the teacher's wife said, "It's not a good relationship. We usually go there sometimes, so there is nothing good about it."

"No tickets are required there, and the price is cheap." Liu Hai added.

Teacher Zhu asked, "Is this going to affect you?"

"No, some of them will be exported from their factory. Foreigners don't want to enter the water, and there are still exports that need to be repaired..." Liu Hai said.

After eating, Teacher Zhu tutored Liu Hai, while Xiao Lin went to take a nap. Children should have a good rest.

"Xiao Hai, you can start learning English." Teacher Zhu said as he was also thinking about Liu Hai's learning.

Liu Hai can not only speak English, but also Russian and German. When he heard this, he immediately nodded: "I listen to the teacher."

"Let's leave a little time at the end and I will speak English to you." Teacher Zhu was very satisfied with Liu Hai's attitude.

"Teacher, does the distance a cannonball flies have something to do with the amount of powder it charges?"

"Yes."

"So how is this calculated?"

"This is more complicated, involving physics, mechanics..."

"Teacher, how did our previous unconscionable cannon calculate the distance?"

"This seems to be an experiment, right?"

"Teacher, how do you calculate the tail fin behind the mortar..."

"this is……."

While taking a break from homework, Liu Hai asked a lot of questions.

"Xiaohai, take this physics book and read it first. If you don't understand something, write it down. If you want to study artillery or something like that, you have to study not only physics, but also mathematics, chemistry..." in the evening. At that time, Teacher Zhu took a physics book and showed it to Liu Hai.

Physics at this time does not have as many things as those studied behind bangs. It can be said that physics in modern high schools is almost equivalent to that in college at this time.

The faster human beings develop, the more knowledge is involved. Later, a physics can be divided into as many majors, and a single mechanics can be divided into as many majors. How many people fall on these simple two words.

Liu Hai went to the Dahongmen Meat Joint Factory again, and took three catties of suet. Of course, it was for money.

When you get home, light a fire. First put some water in the aluminum pot, then clean the pork suet, cut the pork suet into pieces, and put them in the pot. To refine the pork suet, you need to add water first, so that the pork suet will be very white.

Soon the fragrance filled the air. The second uncle, holding a cattail leaf fan and wearing a vest, greeted Liu Hai: "Xiao Liu, where are you refining the oil?"

"Second uncle, have you eaten yet?"

"Eat, you haven't eaten yet?"

"I just came back after going to make up classes."

The second uncle looked at the lard suet in the bangs pot, they were all the best, and there was no way to cover the pot by refining the oil.

Of course, the second uncle didn't ask what was going on. Snakes have their own ways, rats have their own ways, not to mention Liu Hai is still a cadre.

"Brother, I'm refining oil. Come to my house tomorrow night to eat chicken, and the second uncle will come with you." Xu Damao greeted at the door with two chickens.

"Yo, Xiao Xu is not bad."

"There, there, I bought it from a fellow in the countryside."

At this time, movie projectionists are very popular. In many places, it takes more than an hour to go to see movies. In many cases, these chickens cost almost no money, let alone you have to pay for them.

"Xiao Liu is learning to be a fitter?" The second uncle was about to leave when he saw a vise and a file in the next room, so he asked.
