After eating at noon, Yang Liu left the school in a low-key manner, of course, she was accompanied by her bodyguard Long Yu. This time, it was still our Chief Engineer Liu who summoned Yang Liu to leave the school, and the location of the joint has not changed, it is still the café last time.

"I thought you would come to me in a few days, so I could have a good time at school for a few days. Now it seems that you don't want me to study quietly in school at all, but to blow up all the surplus value of **** before joining the army. Yang Liu teased.

"Of course, for the sake of the country, I must do this," Chief Engineer Liu said with great righteousness, "of course we will compensate you for this." I heard that your ambition since childhood was to be an astronaut, I think if there is no problem with your physical test, you don't have to worry about other things, I guarantee that you will be ranked first under the same conditions. ”

"Chief Engineer Liu, I'm very strange, why did you find me, I'm still a junior high school student with no social experience, and I don't even know anything about exports, tariff declarations, or anything." Yang Liu asked the question that he had always been curious about.

Chief Engineer Liu was also surprised and replied, "Isn't it your father who recommended you?" At that time, we had a lot of problems, so we talked to your dad about it. Your father always said that there is a problem to find Yang Liu, she has a lot of friends, and there is always a way. ”

Yang Liu remembered that at that time, his father was leading a delegation to visit Wèn Gold Coast City, and there were many economic and trade negotiations, and Chief Engineer Liu was an inconspicuous representative of many domestic manufacturers. The district elder who has a lot of opportunities is troubled by many business matters of the manufacturer, so he puts all the troubles on his daughter. Unexpectedly, many serious businessmen didn't take the district chief's words seriously, but Chief Engineer Liu took it seriously.

Yang Liu asked with some tears and laughter: "You just came to me recklessly, aren't you afraid that I will accidentally leak the matter?" ”

Chief Engineer Liu thought about it seriously and replied: "It's nothing to leak out, you will at most become a poor child who is used by people with ulterior motives, and no one will hold you accountable for this." ”

Yang Liu said angrily: "Then what are you looking for me for this time?" Am I going to be lucky enough to stay out of the way? ”

Chief Engineer Liu said with a serious face as always: "According to our observation, we found that you are a genius, you have almost never forgotten the things you have seen, and you have the skills of copying in art. So we would like to ask you to visit our factory, and then accidentally put some drawings in front of you. Then you have about ten minutes to jot them down and keep them in mind until you get home. ”

Yang Liu nodded weakly and said, "Okay, but this time I want more." Not only do I have priority in the selection of astronauts, but Long Yu must also have the same treatment. And my dad's place hasn't moved for a long time, and I hope that after my mom gives birth, his level will be improved. ”

Chief Engineer Liu replied with a dead face: "There is no problem with the first one. But cadre promotion has its own rules, even if your father is very good, you can't just break the rules. But I can suggest to my superiors that when your dad meets the minimum promotion criteria, he will be promoted and reused immediately. ”

"Okay!" Yang Liu shook his head unintentionally, "Let's talk about your processing plant, it seems that I heard you say that it is a semiconductor manufacturing company." What do you want me to know? Ion implantation, etching, or what mechanochemical grinding? You know, when I heard you talk about semiconductor manufacturing that day, I looked up a lot of information on the Internet. Maybe you can look it up online and find what you're looking for. If you look for hackers to hack into your factory's computers, it may be better. ”

Over the weekend, Yang Liu and Long Yu visited a local semiconductor manufacturing plant as representatives of sister cities. The so-called semiconductor manufacturing is to manufacture multiple transistors, diodes or field effect transistors on a round monocrystalline silicon wafer, and then cut these millions of small blocks, encapsulate them in plastic, and then lead out some pins to become a finished integrated block chip, which is used to manufacture electronic products such as mobile phones and computers.

Due to the complexity of the chip manufacturing process and the requirement of a clean environment, Yang Liu and Long Yu must participate in relevant training before visiting. They were asked not to carry mobile phones, cameras, recorders and other electronic information recording devices with them, and if they were found to be in possession of these items, they would be immediately confiscated.

After putting on a wide dust-free suit as required, tying his hair into a hat, and putting on a mask and gloves, Yang Liu said to Long Yu: "We will act at the opportunity for a while, once the materials are in hand, you are responsible for diverting the attention of others, and I am responsible for keeping the information in my head." ”

Long Yu nodded silently, indicating that he understood. Now she doesn't know how to get into the secret. After Yang Liu mysteriously explained the matter to her last night, Long Yu felt both nervous and excited. This is the rhythm of the legendary Bond Girl, going deep into the tiger's den to break through many mechanisms, painstakingly obtaining precious information, with amazing memory to keep the information firmly in mind, and then calmly leave, without taking half a piece of paper. What an exciting part of the story! Isn't this the life I've dreamed of since I was a child?

Follow the staff into a passage, and then the two of them feel the wind blowing all over their bodies from top to bottom. The staff said: "This passage is called a wind bath, and the wind from top to bottom can blow the dust off the body so as not to bring it into the dust-free workshop. Our workshop requires no more than 1,000 dust per cubic meter in the air, and even some areas require a higher level of cleanliness. Therefore, we have to put on dust-free clothes and go through the air bath passage, all the items entering the workshop must be kept clean, and even the paper we carry must be special dust-free paper. ”

The staff led Yang Liu and Long Yu to visit the etching area first. The staff pointed to the neatly arranged machines with a glittering stainless steel luster: "This kind of machine is called a physical vapor deposition coating machine, which can ionize some things into plasma under vacuum conditions, and plating some desired ions on silicon wafers under the action of an electric field, completing hundreds of manufacturing processes." ”

Passing over these machines, the staff pointed to another row of machines similar to the previous one, and said: "This kind of machine is called a chemical vapor deposition coating machine, and it is also a kind of machine that coats silicon wafers. ”

The staff used a lot of technical terms and abbreviations in the introduction, in order to make the two guests in front of them impatient and coax the two aunts and grandmothers away as soon as possible. Although the group didn't think that the two young girls would be able to understand the machines and even learn the process of making some of the manifolds, it was better to be careful, even though the area they visited was not yet the core of the entire factory.

When the staff brought Yang Liu and her sisters into a workshop called preventive maintenance, Yang Liu and Chief Engineer Liu met unexpectedly. At this time, Chief Engineer Liu was discussing the maintenance plan of a machine with some tall foreigners, and there was a pile of Wen Jiàn on the table in his hand. Yang Liu pretended to be interested and watched from the side, while Long Yu took the opportunity to pull the staff to ask questions, so that the handsome American young man could deal with it in a hurry. Although everyone is wearing hats and masks, they can't see their looks. But this young staff member has seen Long Yu's appearance without a mask, and in his eyes, Long Yu can be described as a charming young lady, and he is very much looking forward to experiencing an unforgettable date with this Miss Long.

For some reason, today's visitors' dust-free clothes were all washed off for no reason, and the staff had to assign two staff clothes to Yang Liu and Long Yu. Therefore, while Yang Liu stood by and listened to everyone's discussion, he was flipping through the information on the table, and did not attract the attention of others.

While flipping through the pages and trying to remember, Yang Liu also complained: "This damn Chief Engineer Liu also said that it was a little bit of information, which is almost hundreds of pages, I hope Long Yu can complete the task well and give me a little more time." ”

Long Yu was originally a girl with a quiet temperament, but in order to complete the task to the letter, and for the dream of a girl in her heart, she had to dress herself up as a curious baby, and kept asking this and that, and from time to time made a fuss exclamation under the introduction of the staff, the staff occasionally said a few humorous words, and Long Yu also pretended to be amused. So much so that the staff member was full of confidence and thought that he could be a talk show actor.

Yang Liu pretended to casually flip through the information in Chief Engineer Liu's hand, and at the same time pretended to whisper questions to Chief Engineer Liu, as if she was the chief engineer's assistant. Since Yang Liu and Long Yu did not have employee numbers on their dust-free suits, they were taken for granted as intern engineers sent from China. This is also because these foreigners have become accustomed to the frequent appearance of many intern engineers from China, otherwise according to the previous management regulations, strangers are not allowed to appear in the heart of the factory.

About 20 minutes later, Yang Liu signaled with his eyes that Chief Engineer Liu had done it, and sent a message to Long Yu to tell her the same news. Then both groups ended the conversation at the same time.

According to the prior agreement, after Yang Liu and Long Yu left, they would no longer continue to meet with Chief Engineer Liu, but would hand over the information content with other relevant personnel in China.

The landing of the Lu sisters is different from the free-fall descent of the recovery module of the spacecraft on Earth, which can be regarded as a standard soft landing. Because the sisters have prepared enough oxygen cylinders, they can advance in reverse during the descent process, countering the attraction to the end and slowing down the descent. When the rocket descended to a sufficient height, the sisters simply put away the rocket and flew directly into the air to land.
