I tinkered with cars and built a super military industry

Jin Lao once again suppressed his desire to question.

After all, at the end of the day, an X-ray machine will be used.

You can still fix the leak then.

There is system assistance, and Li Yifan has personally installed a tank.

Practice makes perfect, and the main part of the tank was welded on the first day.

The power system, transmission system, steering system, etc. of the car body can be assembled on the next day.

Power devices including electromagnetic track energy storage can be completed.

It seems that the main body of the tank was welded out in one day.

Li Yifan was also a little pleased that the speed of manufacturing tanks this time was much faster than the last time.

At least half a day is faster.

However, there is still the help of Jin Lao.

Although Jin Lao has no substantial contribution in terms of physical strength or tank manufacturing.

But Jinlao helped Li Yifan quickly find the manufacturing equipment in the workshop and all the manufacturing tools.

Otherwise, Li Yifan would be alone in the manufacturing workshop.

You have to build a tank, and you have to find and get familiar with the equipment. It certainly can't be done so quickly.

Compared with Li Yifan's calmness, Mr. Jin felt faintly uneasy.

Li Yifan's speed of manufacturing tanks is too fast.

Today's workload in one day is normally at least a week's worth of traditional tank manufacturing.

In fact, the step of checking and repairing seams is a very important step in the manufacture of tanks.

This step must be done carefully and carefully.

If you are not careful, it will affect the success or failure of the entire tank manufacturing.

As far as the weight of the tank itself is concerned, it starts at least [-] tons.

Ordinary tanks are around sixty tons.

Such a heavy tank travels through various mountainous areas or off-road jungles, which puts the body parts to a very rigorous test.

Especially in some unexpected situations, the tank will move forward at full speed.

The maximum speed of a traditional tank is generally around seventy yards.

Don't underestimate the [-] yards. Running [-] yards in mountainous conditions is considered very fast.

And the tank itself is heavy.

The faster the speed, the more testing the welded structural part of the tank body.

If there is a little bit that is not welded well, under that kind of high-intensity operation.

The tank might fall apart.

Even a gap larger than 0.5 mm will not work.

This thing is like a spider web, it will break as it runs.

Considering that X-rays were still needed, Mr. Jin didn't care.

"Classmate Yifan, let's stop here today!"

"You young man can bear it, but I, an old man, can't hold on." Mr. Jin said.

Li Yifan looked at the time, it was just past seven in the evening.

This time is not too late.

Normally, Li Yifan would work until at least eleven or twelve in the morning.

Because Li Yifan has a problem. As long as he has something to do, he wants to finish it and then rest.

Considering that Mr. Jin couldn't hold on, Li Yifan had no choice but to go back to the dormitory.

If it weren't for Mr. Jin, he would have followed Li Yifan and learned step by step.

Li Yifan immediately started working overtime.

Jin Lao and Li Yifan went to the cafeteria to eat, and then went back to their dormitories.

Li Yifan returned to Jian Ou's small building.

The dormitories of the Chinese Academy of Sciences are all apartment-style dormitories with single suites.

It's a room for one person.

If you have a family with you, you can buy two or three sets.

Everything in the dormitory is free, and working meals in the cafeteria are also subsidized.

So when I work at the Chinese Academy of Sciences, I just do research and development.

You don’t have to think about basic issues such as eating, drinking, sleeping, etc., even in hospitals.

For some workers with families, there are also kindergartens and primary schools in the park.

Convenient for children to go to school.

Of course there are also senior activity centers designed for retired workers.

It is also convenient for parents of some staff members to kill time.

However, the leisure and entertainment in the park seems to be much monotonous.

It's either sports and fitness, or playing chess and fishing.

There is no mahjong parlor.

Li Yifan returned to the dormitory, quickly freshened up, and changed into long-sleeved pajamas.

As time goes by, it is gradually entering autumn.

It's still a little cool in the morning and evening.

Lying on the bed, Li Yifan called his mother.

After nearly a month of recuperation, my mother's recovery is quite good.

I can now get out of bed and walk slowly.

Of course, this also requires special care from the hospital.

After talking to his mother on the phone, Li Yifan called Aunt Bin from his hometown.

Aunt Bin learned that the main body of the large villa in her hometown has been completed.

The fish pond outside my hometown has also been dug into a small lake.

In the next month, in addition to dealing with some details.

The main thing is that the decoration workers come in.

With the construction of a large villa in Li Yifan's hometown.

The originally quiet village end became lively.

Many people who used to go to the head of the village to play now gathered at the end of the village.

Just under Li Yifan's villa.

A villager named Li occupied the land of his home and opened a small teahouse, and the business was booming.

Because of the artificial lake, the environment of this small teahouse is very special.

Anyone who comes here will feel like they are bathed in the spring breeze, which makes people feel very relaxed.

After talking to Aunt Bin on the phone, Li Yifan clicked on the system.

The system panel displays:

[There are still 6/10 left to unlock the upgraded fighter. 】

[Reward: Fighter upgrade and modification experience 3 times. 】

There are only four tanks left to unlock the upgraded and modified fighter jets.

Try to complete the unlocking task in one go at the Chinese Academy of Sciences.

Then I went back to my hometown and took my mother to see the big villa built for her.

......

Early the next morning.

Li Yifan got up early and when he came to sweep the balcony and brush his teeth, he saw Mr. Jin doing Tai Chi downstairs.

It seems that Mr. Jin is even more impatient than himself. He seems to be doing Tai Chi downstairs every day.

In fact, it depends on whether Li Yifan has gotten up. Young people like to sleep in.

If he doesn't get up by the time, Mr. Jin doesn't mind being Li Yifan's alarm clock.

Li Yifan freshened up and went downstairs, and went to the cafeteria with Mr. Jin to have breakfast.

Then the two went into the basement where the tanks were made.

After Li Yifan entered the manufacturing site, he did not use X-rays to check for leaks as Jin Lao imagined.

Instead, the gantry crane was used to install the engine directly.

Mr. Jin endured it all day yesterday, originally thinking that Li Yifan would use X-rays to check for leaks today.

Unexpectedly, Li Yifan was going to install the engine directly when he came today.

Mr. Jin finally couldn't help but asked:

"Classmate Yifan, wait a minute. I'll help you check for leaks with X-rays."

Mr. Jin pretended not to see Li Yifan hoisting the engine.

This not only saves Li Yifan's face, but also achieves his purpose of checking for leaks.

Mr. Jin took the X laser gun and scanned each welding rod very seriously.

Li Yifan didn't respond to this. He almost forgot that only he had the ability to scan the system.

Li Yifan can skip this step, but Jin Lao and the others cannot.

Relatively speaking, the step of using X-rays is still considered the most important step by Jin Lao and others.

If you make this wrong move, everything will be ruined.

Jin Laogang started using X-rays to check for leaks, and his expression was quite normal.

As more and more solder joints were detected for leakage, Jin Lao's expression began to become complicated.

Because there are many places where welds are prone to appear on the tank body, there are none on this tank body.

Strange.
