Because Lin Su and Lin Weiguo came back during the day, when Lin Su returned to the family home, there were almost no people in the family home. There are two of them, father and daughter, and one of them will go to their room if they don't meet each other.

Director Lu gave Lin Su half a month's vacation, and Lin Su was still looking forward to this holiday.

In the past six months since Lin Sujin entered the Provincial Machinery Factory, he really pushed himself too hard. The leaders of the Provincial Machinery Factory felt that Lin Su could write such an excellent manual, and they must have a deep understanding of mechanical knowledge.

Therefore, some leaders in the provincial machinery factory, especially the director of the road, have always had great expectations for Lin Su. Although he didn't say anything now, he just let Lin Su learn from other masters in the production workshop.

But Lin Su knew that it wasn't necessarily when, maybe Director Lu would send some tasks to him. It's like this time she suddenly received a comrade and went to the machinery factory in J City to help them repair CNC machine tools. Lin Su didn't want her to drop the chain when she was needed in the factory.

In addition to the leaders of the provincial machinery factory, Professor Liu also had high hopes for Lin Su. Although Lin Su is only in some aspects of the basics of machinery, his mastery is not particularly good. However, thinking of Lin Su's previous learning experience, Professor Liu also feels understandable.

It is precisely because of this that Professor Liu feels that Lin Su's talent in this area is very high. So in normal times, Lin Su is also very strict. In addition, Professor Liu's level is indeed very powerful, and every time he assigns a task to Lin Su, he is just stuck on the upper limit of Lin Su's learning

So during this time, Lin Su studied in the factory during the day and studied with Professor Liu at night. When he returned to the dormitory and rested on the bed, Lin Su also exchanged some relevant materials through the system to study.

In the past six months, although the food of the provincial machinery factory is very good. When she is fine, she will also go to Professor Liu to open a small stove or something. However, Lin Su has indeed lost a lot of weight in the past six months.

Now that he has half a month's vacation, Lin Su feels that he can also relax a little.

Moreover, Lin Su came to work in the machinery factory at the beginning, not because she liked this job so much. Instead, Lin Su hopes to use this work as a pedal to realize some of his plans.

Lin Su has learned a lot during this time, although there are still many gaps compared with some people with strong abilities. However, Lin Su also has his own advantages. It is that she came from the later generations, and she has a certain forward-looking knowledge of this time. Moreover, she also has the help of the system. At this point, she is already "powerful" than the vast majority of people in this world.

Thinking of her future plans, Lin Su had to say that she was still lucky, and it was her left arm that was injured. She wants to write and draw at home, or do some daily things, without delay.

For a period of time after that, Lin Su stayed at home and didn't go out. Lin Weiguo, on the other hand, went to work in the factory every day, and when it was time to eat, he would go to the canteen or state-run restaurant to buy something and bring it back to Lin Su to eat.

I don't know if it's because when Lin Su was in danger before, he asked the system to help improve her physical potential in a short period of time. Anyway, Lin Su felt that the speed of his wound recovery was particularly fast.

Although the wound on her arm was not particularly deep, it was relatively long. In just two or three days, her wounds began to scab over, and within a week, some places on her wounds had begun to grow new skin.

This week, during the day, Lin Su recalled the structure and details of some more advanced CNC machine tools he had seen at home when he was in school and factory. Then, she recorded it in the notebook and inserted the knowledge she felt she could use into the mechanism of the CNC machine tools that are commonly used now.

When she couldn't sleep in bed at night, she immersed her consciousness in the system. Please ask the system to simulate the parts and structures of CNC machine tools commonly used in China, and try to insert them into this CNC machine tool by thinking of what she thinks of as being more advanced than now, but not too much advanced. And some of its programming structures, make changes.

Because Lin Su himself knew that his ability was not particularly strong. So, she's not too greedy. Where she changed, she didn't change much. However, the combination of several places after the change will greatly improve the efficiency of the CNC machine tool.

Moreover, after modifying those places, it will greatly reduce the wear rate of the machine and increase the service life of the machine.

Of course, there is also a particularly important place, that is, if Lin Su's modification method is followed, there is no need for the machinery factory to buy the machine again. As long as you find a few high-level skilled workers, modify a few places, and install a few parts.

In this way, costs can be reduced. There is also no need to stop the production of the machine factory, which will cause losses to some machine shops.

Because of the help of the system, Lin Su can verify his ideas in his mind countless times a day. That's why it only took her one week to make the finished product.

The holiday given to Lin Su by the director of the road factory is still a week away. When he just got this holiday, Lin Su also thought about taking a good rest and relaxing at home.

However, she didn't expect that she would succeed so quickly. In his mind, after the successful transformation of the now commonly used CNC machine tools, Lin Su couldn't stay at home at all.

At this time, she was very eager to return to the provincial capital and discuss her series of ideas with Professor Liu

"What? You want to go back to the provincial capital tomorrow? Didn't the director of your road factory give you half a month's vacation? You are in such a hurry to go back, is there something wrong with your machinery factory?"

After eating in the evening, Lin Weiguo, who was chatting with Lin Su, suddenly heard Lin Su say that he wanted to go back to the provincial capital, and he was a little surprised.

"No, nothing happened to our machinery factory, I wanted to go back on my own, I ......"

"Since you want to go back, then, I don't agree with you going back to the provincial capital now. ”

Seeing that Lin Su seemed to want to say something, Lin Weiguo lowered his voice, sat next to Lin Su, and persuaded Lin Su softly.
