The ups and downs of life in the Siheyuan

In the next few days, Li Yuan would always see kittens on the wood pile at his home after get off work.

Every time she looked at him quietly, her eyes seemed to have a little more sparkle.

He took out a small fish that he had specially caught in Shichahai with his mind.

There are more than 100 pieces, large and small.

He took the small fish and slowly approached the wood pile. This time the kitten did not move, its big eyes stared at Li Yuan for a while and then stared at the small fish.

Li Yuan put the fish in front of it and took a step back. The kitten glanced at him and lowered his head to pick up the small fish.

Turn around and jump behind the pile of wood and start eating.

Li Yuan smiled, turned around and opened the door.

"Yuanzi", Yan Fugui's voice came from behind.

"It's the third uncle," Li Yuan turned around and smiled.

"This cat has been coming here a lot these days, do you want me to get rid of it?"

"No, it's quite pitiful. I gradually got to know him, and he's also a companion."

"Well, I was afraid you wouldn't like kittens."

"The kitten is very cute."

"Yes, it is quite difficult to live alone. How are you and Xiao Zhao?"

Li Yuan had a headache, and it was hard for him to accuse Yan Fugui of being nosy.

"Good!".

Yan Fugui looked a little stunned, "That's good, that's good." After saying that, he said goodbye and left.

Li Yuan looked at Yan Fugui's back and roughly guessed what he was thinking.

It should be that he wants to introduce someone to himself again.

With Yan Jiecheng, the Yan family must know his abilities and want to get closer to him.

Li Yuan shook his head silently and turned back to the house.

"His father, what did Motoko say?"

"They haven't stopped yet." Yan Fugui's tone returned to calmness.

"Then what should I do? My niece is not young anymore. If I don't find her, I will lose her."

"Forget it, Motoko is by no means a thing in the pool, and your niece is not worthy of it. Once you hate him, you will lose more than you gain."

"The main reason is that I feel uneasy when I see Motoko alone."

"Haha", Yan Fugui did not answer.

Li Yuan returned home and had a sumptuous dinner.

Take out the drawings and continue the design of the single-cylinder four-stroke diesel engine.

This is what he learned in Xiangjiang, and he wanted to design a cost-effective engine based on his understanding.

In addition to considering power, this engine also needs to focus on reliability, maintainability and manufacturability.

He has been working hard on it for several days, but unfortunately the information is incomplete and he can only imitate European and American products from the s and s.

He thought of designing a small hand-engined engine to test the theory first, and then consider other things.

For this other, he placed his hope in the system.

Because he discovered a rule, as long as it is something he needs very much, the system will usually meet his needs.

In recent months, he has not been able to draw skill books. He thinks that the design made after the new year is too simple.

The design of those wrenches was completely within his control, so there was no trigger system.

When designing the engine this time, I actually came up with this idea when I was in Xiangjiang.

So there, I took advantage of the convenience and searched for some related books.

It is a pity that Xiangjiang has not developed in the direction of engines. There is very little information, and there are no design drawings of the latest engines.

These days, when he signs in every morning, he is very religious, hoping to get a response from the system.

Unfortunately, what we get every day are daily necessities.

Now he hopes to design a prototype and look forward to triggering the system.

A month later, a prototype of a horizontal-bar four-stroke engine made entirely of walnut appeared on his desk.

The appearance looks very delicate, similar to the small four-wheel diesel engine of later generations, but the scale is reduced by 10 times.

All parts are complete, but unfortunately it cannot be started and can only be rotated manually.

With excitement, he called up the panel and clicked to sign in.

This was today's opportunity to sign in. He deliberately stayed in the present, hoping to get a miracle.

With a ding-dong sound, 10 pounds of white flour and a pig's head appeared in the sign-in column.

He looked at these items, smiled bitterly, and put them into the space.

It seemed that the way to open it was wrong and he needed to continue to explore.

Play with the engine model for a while and put it in the bookcase under the stairs.

I went to bed feeling depressed.

Wake up the next day, follow the routine step by step, go to morning classes, cook, eat, and sign in.

Very skilled operation process, but unfortunately no miracle happened.

He knew that a wooden model would not impress the system.

His next goal is to reproduce an engine that can actually start, even if it is a model.

He put the wooden model into the space, then found a piece of wood of similar size and wrapped it in a sheet.

Put the package in the back seat and rush to the unit.

At 9 a.m., he stayed in the office for half an hour to make sure no one was looking for him.

He replaced the items in the package and walked out of the office holding it in his hands.

"Motoko, what are you talking about? I am a good proletarian cadre with a strong will. Don't think about corrupting me by giving gifts."

Lu Xingyu looked around at the package placed on the desk and joked.

"Hey, it's a big gift, a gift you can't refuse."

"Ouch, that's not a small tone!"

He turned to look at Li Yuan and reached out to unpack the package.

"I want to see what you are going to use to test the cadres."

The package opened easily, but when the last piece was opened, he froze on the spot.

"Ahem...", maybe because he was too excited, he choked on his saliva.

He no longer paid attention to Li Yuan, his eyes were completely attracted by the handicrafts in front of him.

He murmured: "Brother, where did you get such exquisite things?"

I accidentally moved my hand on the flywheel, and the flywheel slowly turned half a circle.

There was a roaring sound from the engine.

"Oh my God, it can still move. Can these screws be real?"

He put his hand on the fastening screw and asked in wonder without looking back.

"Every part is real, but the material is wood."

He opened his eyes wide and turned to look at Li Yuan.

"Are you kidding me?"

Then he took out some universal wrenches from the drawer.

Find a small wrench and put it on the screw.

Before exerting force, he turned his head and looked at Li Yuan again, "I'm going to use force!"

Li Yuan raised his hand calmly and said, "Don't worry, it won't break."

He withdrew his gaze, adjusted the wrench, and applied gentle force on his hand, fearing to damage this lifelike screw.

There was no movement from the screw, so he quickly took away the wrench and looked at the faint mark left on the screw with distress.

"You won't lie to me," Lu Xingyu confirmed again.

"Looking at how distressed you are, I still have samples here." With that said, Li Yuan took out the spare screws from his pocket and handed them to Lu Xingyu.

He took the screw and looked carefully. Except that it felt like wood, the shape and lines seemed to be no different from real screws.

He picked up the wrench again, applied a little force, and the screw came loose.

He slowly unscrewed the screws, picked it up and compared it with the sample before, and found that they were exactly the same.

With disbelief, he picked up the wrench again.

An hour later, he seemed numb looking at these delicate and small parts on the table.

"Did you make all of these yourself?"

"Li Yuan nodded."

"Brother, your hands are so skillful. I like this model very much."

He picked up the parts and played with them fondly.

"Lao Lu, don't you have any other ideas?"

"What do you think?" Lu Xingyu looked wary.

"Brother, I like things very much, but don't let me use the back door for you."
