To be honest, Jiang Yan really couldn't bear to pour cold water on Director Liu, this reverse imitation is actually a simple matter.

In reverse mapping and imitation engineering, it is actually very common for the designer to accurately grasp the original purpose and intent of the designer only by relying on the actual final product and drawings and other materials.

Without the original first-hand design information and the narration of the parties, many products seem to be designed that do not conform to technical rationality and laws, and their original intentions are often impossible to figure out.

So there is a choice in reverse imitation, that is, if you fail to understand the product, you must ensure that no part is missing in the reverse imitation process, even if the part is not useful in the process you speculate.

It's just that now the engine of the little devil's motorcycle is also an imitation, but Jiang Yan basically understood his design ideas through last night's research, not so much a reverse imitation, but a drawing of the drawings that exist in his mind.

The power of this little devil's imitation Harley-Davidson motorcycle's engine is only eighty percent of the power of the original engine.

Jiang Yan has the drawings of the original Harley motorcycle engine in his hand.

After thinking about the reasons, I said that I was optimizing and upgrading.

In less than a few hours, the news that Jiang Yan could repair the engine had spread throughout the maintenance office.

The next time is basically Jiang Yan's own performance time, Jiang Yan is not like other masters. The more people learn this thing, the easier it will be for themselves.

So whenever Jiang Yan is disassembling the engine, he is always surrounded by people on the inside and outside of the three layers.

In order to take care of them, Jiang Yan's disassembly speed also slowed down, and he explained the function of each part while dismantling it.

A strange scene happened in the workshop, a large group of people in their thirties and forties, holding their own notebooks, listening to a thirteen-year-old child holding parts and talking about where to go, and they nodded and recorded while listening.

The only thing that made Jiang Yan wonder was that when he came yesterday, he didn't see such many people! How did so many people pop up in the blink of an eye.

Anyway, a sheep is also driven, and this group of sheep is also released. It can only be left to its own devices.

In this way, Jiang Yan was under the watchful eyes of everyone, explaining while dismantling.

Even when Jiang Yan was eating, someone took a small notebook and asked Jiang Yan questions.

Just such a week passed quickly, Jiang Yan was like a fish in water in this research institute, and everyone who saw Jiang Yan called Jiang Yan a little teacher.

Now Jiang Yan's words in this research institute have time to be better than the director.

Especially Daniel Zhang and Wang Dabao, who first followed Jiang Yan, often regarded themselves as Jiang Yan's apprentices.

Manual work such as running errands and filing parts, these two people are rushing to do it. Jiang Yan was also happy, but Jiang Yan did not treat the two of them badly, and he taught each other in terms of technology.

After a week's hard work, Jiang Yan and their team successfully repaired almost five small RB tripods and two Willis MB jeeps.

The mapping of the parts also went smoothly, and everything seemed to be in order.

At the end of November, the weather has become much colder.

It was Sunday, and Jiang Yan, who had just finished breakfast, took He Yuzhu and Xu Damao to move their muscles and bones, and led them to Yongding River with a fishing rod.

Not long after he went out, a little devil's "nephew" stopped at the door of the courtyard.

The three people in this car were none other than Zheng Chaoyang, Bai Ling and Hao Pingchuan.

"Bah, I said Hao Pingchuan, you can't drive! Why do you go to places with big ashes and pits, you see that I have eaten dust along the way. ”

"That's it, that's it, are you familiar with the alleys of Sijiu City? Didn't I say let me ride, you have to ride it yourself, do you know the road? ”

"I'm not blowing it to you, if I had ridden it, I wouldn't have taken so many detours."

The vehicle repaired by Jiang Yan in the maintenance center has greatly improved the transportation of the Public Security Bureau, and the "nephew" that Zheng Chaoyang and the others rode was repaired by their maintenance center.

Otherwise, it is estimated that they will at most ride a bicycle as a means of transportation.

"Okay, you two don't quarrel, hurry up, don't be a mistake." Bai Ling saw that the two of them were about to enter the bickering mode again, and hurriedly opened her mouth to stop it.

The two of them saw Bai Ling speak, so they stopped.

The white-collar worker took out a bag from the funnel and two boxes of pastries.

"Bai Ling, when did you buy this thing, why don't you tell the two of us!"

Bai Ling, who heard Hao Pingchuan's words, glanced at him and did not say anything.

And Zheng Chaoyang, who also came down from the "nephew", was very attentive like a dog's leg, and the result was what was in Bai Ling's hand.

"Don't park at the gate, hurry." As he spoke, he walked towards the courtyard.

Na Cheng thought, and this time he met Yan Bugui, who came out of it and was holding his own urine basin and was about to go to the toilet.

Yan Bugui's daughter-in-law just gave birth to a child two days ago, and this time she still gave birth to a son, which made Yan Bugui worried.

It is often said that this half-grown son eats the poor old man, counting this newborn boy, he already has three sons. There are five mouths in the family waiting to eat, and it is difficult to get your own salary!

"Teacher Yan, where are you going?" Seeing Yan Bugui coming out, Zheng Chaoyang hurriedly said hello.

"It's Zheng Gong'an! You're here to find Xiaoyan. ”

For a while, Hao Pingchuan took Zheng Chaoyang and Bai Ling to run into the courtyard every once in a while, and they came more often than Zheng Chaoyang went back to his home.

Especially Hao Pingchuan, he came more diligently, and his purpose here was very simple, purely to fight tooth sacrifices.

However, this product seems to be particularly good for Grandma Lu's taste, and the relationship between the two is quite good.

Over time, the three of them became familiar with the people in the courtyard.

"It's not a coincidence that you came this time, just now Xiao Yan just took a group of children to go fishing in the Yongding River."

"It's all the two of you who are grinding, it's too late this time!" Hearing Yan Bugui's words, Bai Ling complained to Zheng Chaoyang and Hao Pingchuan.

After saying this, Bai Ling said hello to Yan Bugui and walked directly to the courtyard.

Hao Pingchuan and the others also said hello to Yan Bugui, and they also walked towards the courtyard with a frown.

Since Jiang Yan is not here, Grandma Lu must be at home, and now she can only say hello to Grandma Lu and go to Jiang Yan first.

"This Xiaoyan's network ability is really big, there are public security officers in this yard who often come and go, so I am not afraid that someone will come here to make trouble, and I have to talk about my family when I go back, and I will go to see the old lady more in the future. Let them play with Jiang Yan more, maybe they will be able to use it at any time. ”

Yan Bugui stood at the gate with a urinal, looking at Zheng Chaoyang, he asked the background of the three people, and his heart was full of small calculations.

Since today is Sunday, the people in the courtyard are basically there, and when they saw Zheng Chaoyang and the three of them walking in, everyone greeted them one after another, and the three of them responded with a smile.

The steps of the three of them were very fast, and after a while, they came to Grandma Lu's house in the backyard.
