Ding, the wishing system is at your service, what is the wish of the host?"

"System, among these five tractors, help me pick out one tractor with the least engine damage, and I can repair the tractor under your guidance. ”

"The host needs to spend a primary wish, may I ask if the host can redeem it?"

"Redeem!"

"If the wish is met, the host will make a wish! The host will spend a primary wish in exchange for the system to help select the right machine. Now that the selection has been made, ask the host to select the second tractor on the left. ”

Hearing the system's words, Lin Su did not hesitate at all, and walked directly to the tractor.

"Is this it?"

"Yes!"

Hearing the words of the system, Lin Su, who had already selected a suitable machine, was in a very good mood at this time.

In order not to make himself look abnormal, Lin Su looked at the past on these machines very seriously, and stretched out his hand from time to time to knock on the machine. The chassis of the car will also be opened to see what the engine is like.

After grinding for nearly half an hour, Lin Su came to Director Lu and Director Zhang, and said to them: "Factory Director, Director Zhang, I have selected, I want to buy the second one on the left." ”

Director Zhang and Director Lu have been talking here during this time. Lin Su's movements, they also saw it. also knew how hard Lin Su had to pick out a tractor that she was satisfied with.

Out of the relationship with Director Lu, Director Zhang glanced at Lin Su and reminded again: "Comrade Lin Su, I have to make it clear to you." The tractors that can be repaired in our factory have been sold as second-hand by us. Now the rest of these are not repaired by the masters of our factory.

You want to buy a tractor with us, of course we are happy. However, you have to be mentally prepared that after you buy this tractor, it may not be repaired well. ”

Hearing Director Zhang's kind persuasion, Lin Su was of course very grateful to him.

Lin Su thanked him very sincerely, but still insisted on his decision.

Seeing that Lin Su had already made up his mind, Director Zhang couldn't say anything more. I could only find someone to come over and transport the tractor selected by Lin Su to the Provincial Machinery Factory.

Because the director and secretary of the factory had promised that if Lin Su had new research ideas, they would try to make it as convenient as possible.

Although he had to worry about the thoughts of the other workers in the factory, Director Lu did not have the means to provide Lin Su with a good engine.

Even, because Lin Su's research direction this time was different from their machinery factory, they had no way to give Lin Su other help.

However, some basic conveniences that they can still provide.

From the moment the tractor was pulled back to the Provincial Machinery Factory, the director of the road factory gave Lin Su a privilege. She only needs to work in the production workshop for half a day every day, and the rest of the time, she can modify the engine of this tractor.

For the support of Director Lu, Lin Su is of course very grateful.

Although she only spends half a day in the production workshop every day, she also tries her best to complete all her work and not cause trouble to others.

In fact, there is not much work in their production workshop. Lin Su usually does everything very quickly.

So, although it only comes for half a day every day. However, she never delayed her work.

In this way, whether it is the workers in the workshop or the leaders in the provincial machinery factory, they have a better impression of Lin Su.

For them, those who don't cheat and play tricks are good comrades.

I don't know if it's because I've transformed CNC machine tools before, or because Lin Su is indeed very talented in terms of engines.

After Lin Su brought the tractor back, he first exchanged it with the system for a book that could repair all engine failures.

Just this book cost Lin Su an intermediate wish, which made Lin Su very, very distressed.

If it weren't for the fact that she had already spent money to buy the tractor back at this time. In order to learn the first knowledge about engines, she spent so much time and discussed with Professor Liu so many times. Lin Su must have given up this project directly and turned to study other projects.

However, Lin Su's previous investment was already very large, and if she gave up now, Lin Su felt a little reluctant.

Therefore, she could only grit her teeth and spend an intermediate wish to buy this knowledge.

However, after receiving this knowledge, which cost her an intermediate wish, Lin Su found that she had wronged the system. This mid-level wish is indeed worth the cost.

Because in the stack of materials given to her by the system, there are not only the repair methods of the tractor engine that Lin Su urgently needs now, but also the repair methods of other engines.

Among them, the highest should be the repair data of the engines of some machines in the aerospace field.

And all this is, Lin Su didn't expect it.

Besides, although this is all about some engine repair methods. However, if you want to repair the machine, you need to be very familiar with at least this type of engine.

Therefore, these materials say that various engine repair methods are used. However, if it is used well and mastered clearly, it can even be said to be an instruction manual for all engines.

If you can really master all these things, it will be very beneficial for Lin Su in the future.

It was precisely because Lin Su thought of this that he always had a feeling that he had taken advantage of it.

You must know that in the recent period, Lin Su has encountered a lot of things. Therefore, the wish value she has saved up over the years has also spent a lot.

Some time ago, when she counted the wish value she spent during this time in the system, she was still distressed there.

I didn't expect to encounter such a good thing now.

It's like going to the supermarket to buy something, gritting your teeth and buying daily necessities. It was because the price was too high and I was distressed, but as a result, I opened the package and found that there were more gifts than the original ones, and they were even more valuable. The feeling of taking advantage of the situation really makes anyone feel very happy.

Although because she was at this time, she had not thoroughly understood the knowledge of the tractor's engine. So, the tractor hasn't been repaired yet

However, when Lin Su was working these days, he was still very interested.
