After chatting with Liu Xiaohui for a while, and after hitting the confidence of other parents by the way, Liuyun stepped on the bell at the end of the exam and returned to the examination room......

After Liuyun left, a few parents who were familiar with Liu Xiaohui came over again, and someone asked worriedly: "Head Nurse Liu, where is your child going to go to?" ”

Liu Xiaohui smiled: "Continue to high school." ”

All the parents around were relieved: fortunately, they were not ready to go to secondary school......

The second, and last session of the morning, was Mathematics.

This time, Liuyun took less time, and in thirty minutes, he handed in the paper. This time, all the parents learned to be smart, and when they saw Liuyun coming out of the examination room, they hid far away......

In the afternoon, physics, chemistry and biology were examined, and on the second day, history, foundation and ideology and politics were examined......

And within ten meters of the flowing clouds, it has also become a forbidden area; Then, Liuyun also became the most unpopular person among his classmates: "Whoever in other people's families" is treated like this.

After the high school entrance examination, Chen Zheng and Chen Yang returned to school; Chen Jing, who had just finished the exam, was completely idle......

After estimating the score, Chen Ning, who had more than 90 math and a total score of less than 300, directly gave up resistance, obeyed Chen Jingfeng's arrangement, and went to the fleet's overhaul factory......

Also going with Liuyun: the admissions teachers of various secondary schools came to the door twice in three days to introduce him to the various benefits and benefits of his school, which made him a little overwhelmed.

Because of the fame of "Master Liu", Liuyun made an exception to participate in the grading exam.

After Xiao Lu suppressed a group of masters, Liuyun turned into a sixth-level worker in the three materials of car riveters: the factory only has the qualification of setting the sixth level.

Chen Ning, on the other hand, "unfortunately" became an apprentice under Liuyun; And together with Chen Ning, under Liuyun's hands, there is also Chen Ning's good friend, the little fat man Lu Peng.

After knowing that it was an acquaintance who brought him, he was very happy for the little fat man Lu Peng: the days ahead will be much more moisturized!

But Liuyun's second brother Chen Ning is not so optimistic: when the old man left home, he brought a large bag of books, which were not idle books that the old man used to pass the time, all of them were professional books on machinery......

After going to work the next day, the little fat man Lu Peng found that when he left the campus and entered the factory, he just jumped from one pit to another, and his studies continued.

The little fat man who has been wound at home can only touch the notebook and listen carefully to Liuyun's three-view in mechanical drawing......

After Liuyun finished speaking, the results of the high school entrance examination also came out......

Chen Ning and Chen Jing's scores coincided with the estimated scores, and Liuyun's scores were more than a dozen points away from the pre-estimated, not less, but more: there was a question left in each subject that was not done, but in the end they still got a full score......

When some parents reacted to the Education Bureau, the Education Bureau gave a reason that made most parents grit their teeth with hatred: the other questions on the student's paper were not wrong, and the handwriting was neat, and we had reason to believe that the student was fully capable of getting full marks; Those empty questions are just to take care of the self-esteem of other students, and they are deliberately left undone, which is worth advocating......

Hearing the reason of the education department, which can be called "extinction of humanity", Liuyun's head suddenly circled: it is conceivable that when they meet their classmates, they will definitely greet their eighteenth generation ancestors with "affectionate" eyes......

After filling in the volunteers, Liuyun found Cheng Chong, who was full of spring, and told him about his volunteers......

After some bargaining, Cheng Zhong agreed that Liuyun would "step on two boats": the student status would stay in school, and he could go to work in the overhaul factory......

After the deed was completed, Liuyun slapped a golden leaf on Cheng Chong's desk. Before Cheng Chong refused, Liuyun left a sentence of "Master, I am now a sixth-level worker", and walked away, so shocked that Cheng Chong didn't say a word for a long time......

Liuyun, who returned to the overhaul factory, began to take on some simple parts processing tasks: Chen Ning and the little fat man Lu Peng have almost digested the three views, and it is time to study the parts diagram......

After following Liuyun's ass and watching the processing process of the parts, Chen Ning realized that the drawings were still far from the finished product, and the machining was not as simple as he imagined......

A simple drawing with a keyway stepped shaft, in addition to the basic dimensions marked on the drawing, with tolerances and roughness; There are also process requirements for heat treatment in the technical requirements. If it weren't for the feed method of the turning tool during the machining process, Chen Yang wouldn't know what the retract groove was for......

This is still the most basic, after hearing Liuyun talk about rough cars and fine cars, Chen Ning felt that his brain was a little insufficient......

Seeing that Chen Ning was a little struggling to learn, Liuyun was also a little helpless.

In the machinery factory decades later, there are still lathes who know how to process parts, and the processing process of parts is compiled into a process card by the process personnel, and the lathe is processed according to the process card. In some machinery factories with a high degree of automation, the processing process is imported into the CNC machine tool, and the lathe worker only has to put the blank and take the finished product every day......

At present, Chen Yang and his little friend Lu Peng still have to learn how to process the workpiece with a rough turning tool, and then change the tool, adjust the spindle speed, and complete the final processing of the workpiece......

In order to facilitate the study of his brother and his little partner Lu Peng, Liuyun took time to compile a manual of machining technology.

With the little cheats in hand, Chen Ning and Lu Peng's learning progress is much faster. But later, because "good things need to be shared", the craft manual spread in the overhaul factory......

As the owner of intellectual property rights, Liuyun obtained the right of authorship of the printed version and the 200 catties of meat tickets awarded by the factory.

Because the "secret book" was leaked from his own hands, Chen Ning also apologized to his brother......

But Chen Ning found that Liuyun didn't seem to care a little......

Isn't this booklet that important?

Liuyun saw Chen Ning's doubts, and explained with a smile: "No matter how good this booklet is, it can only help you get promoted to the fourth or fifth level worker, and then go up, it will take time to grind!" ”

"Then you ......" Chen Ning stared at Liuyun curiously

Liuyun glanced at Chen Ning: "Second brother, you are too greedy!" ”

"Aren't I curious?" Chen Ning smiled and touched his nose.

Liuyun sighed: "When will you be able to get the fifth level exam, and then calm your mind, you will know what is going on with the eighth level worker!" ”

"Really?"

"Am I lying to you?" Liuyun glared at Chen Ning, "However, it's not so easy to calm your mind!" ”
