"stop."

Ji Xinghe took Xinxin and stood behind Shen Mu. When Shen Mu wanted to turn his fingers up again, he said, "That's it."

Shen Mu's finger rested on the third to last item on the demand list for operating section 109: a maintenance project requirement. The system's estimated completion time is 864 hours. The hour here is the time unit of the Azure Star, the rising sun on the alien planet. Sunset is completely different from Azure Star. A day does not have 24 hours, but it doesn't really matter because everyone basically lives in the underground base and rarely sees the sun.

Although this time is not the time for the base's artificial intelligence program to combine robotic arms, machine tools and other advanced technological creations to repair required parts, it is just because the relevant resources are allocated according to priority. The 864 hours are almost all waiting time, but It can also be seen that the maintenance of this part is very difficult.

"Old Ji, can you do it?" Shen Mu glanced at Master Liu next to him and asked in a low voice: "This is beyond the level of an eighth-level fitter. Even if your hands don't shake, you may not be able to complete it. "

Ji Xinghe noticed that Master Liu pricked up his ears, and suddenly regretted pretending to be so cool just now, but he had to pretend to be so cool even while kneeling.

"As I said, the reason why I am a level eight fitter is because the highest level of a fitter is level eight."

Ji Xinghe actually has a way out now. The advantage of being older is that if he gives up now and goes to repair the car, no one will really trouble him. But he has to make himself have no way out, because life is like this. If you take a step back, you will completely lose the possibility of taking another step forward. You may have new opportunities when you are young, but Ji Xinghe is really not young anymore, and it is natural for others to call him Lao Ji.

"Okay, okay, just be stubborn."

Chen Mu complained a little, but he still explained some key knowledge points to Ji Xinghe immediately. As a second lieutenant-level expert mechanic, he was familiar with all federal standard mechas and all their parts. This was also the reason for Ji Xinghe. Let Chenmu help you choose.

As Ji Xinghe listened, his eyes became brighter, because he found that what Shen Mu said was exactly the same as the information he could see. And because of the confidentiality level, there were some information that Shen Mu could not see. Told him everything.

Can do it.

"Here, bring me this broken part." After hearing this, Ji Xinghe looked at Master Liu: "If I can't fix it, I'll buy you a new one immediately. If you don't believe it, I will I can transfer the contribution points to you first."

Master Liu, who just felt that he was almost cheated, didn't dare to ask for Ji Xinghe's deposit. He hurriedly nodded and agreed and expressed his willingness to provide all the tools. Anyway, the tools needed by the fitter are not uncommon and he has spare ones here.

"Repair it, let's fix it. If it's broken, I don't need your contribution points. We don't have time to repair it anyway. The queue time now is more than 800 hours. In a few days, it may still be more than 800 hours. If you prioritize it, it will be better." When the queue-jumping situation occurred, our original plan was to wait, but if we couldn’t wait, we would just replace the parts instead of repairing it.”

Master Liu looked at Ji Xinghe, who was the same generation as his grandfather, and suddenly sighed as he spoke, "Mr. Ji, I really don't want to embarrass you. I am really short of eighth-level fitters. I am short of them in all operating areas here. In other bases The situation is the same. But at your age... we don’t dare to bet, because if we lose, we will die."

Ji Xinghe breathed a sigh of relief when he saw someone going to the warehouse area to pick up the damaged mecha parts.

"Master Liu, I'm sorry because I was too excited. I can understand you. I'm sorry, but I really need this opportunity. I won't let you down."

The most important among you is not Master Liu, Shen Mu, and Su He, but Ji Xinghe’s granddaughter. While waiting for others to prepare, he squatted down and started talking to Xinxin, because he would have to work hard soon and had no time to take care of her. Xinxin.

Chen Mu and Su He stepped aside knowingly. Shen Mu, who originally wanted to emphasize some key points, was actually pulled away by Su He. The two stood outside the line drawn in the No. 109 operation interval.

Su He asked in a low voice with some curiosity: "Is the eighth-level fitter very powerful? How do you judge whether Lao Ji is good or not? Does it depend on the machining accuracy? Millimeters and nanometers or something."

Shen Mu looked at Su He in surprise: "You don't know this?"

"I'm not sure. I just know that machining accuracy is very important. It refers to the degree to which the actual size, shape, and position of the three geometric parameters of the surface of the processed part are consistent with the ideal geometric parameters required by the drawing. The smaller the number, the better. "

"Yes, this is indeed the processing precision. Nano is already the limit of our human technology."

"The old man is an eighth-level fitter. Can he reach the nanometer level?"

"..." Shen Mu, who originally didn't want to explain this question, noticed that Su He's camera was on, and thought that he would definitely appear in Ji Xinghe's documentary in the future, so he answered seriously: "No, don't talk about it. Ji is an eighth-level fitter, even if he is a ninth-level fitter or a tenth-level fitter as he said, it is not enough because the limit of human machining accuracy is only three decimal places in the unit of millimeters."

"That is to say, the processing accuracy can only be 0.001 millimeters at most?" Su He said blankly: "But one millimeter is equal to one million nanometers, and one nanometer is 0.000001 millimeters. The difference between two zeros and five zeros is too big. Is it big?"

Shen Mu took a deep breath, calmed down the complex emotions of facing the low-end problems of laymen, and continued to explain seriously: "It's not just the difference between two zeros and five zeros, it's also the difference between 0.009 and 0.001 It's also very large... Let's put it this way, I can achieve a manual accuracy of 0.009 mm, but I can't guarantee that I can achieve a manual accuracy of 0.001 mm. I'm not talking about one time, but in my entire life."

"you?"

"What's wrong with me?" Shen Mu held his head high: "I am Shen Mu, the youngest second lieutenant mechanic in the Federation. I just came to Alien and I got a subsidy of 30,000 contribution points before I made any achievements. Do you know why? ? "

"Why?"

"Because the maximum subsidy for special talents is only 30,000, and I...wait a minute, edit this section and start again." Shen Mu coughed twice and then said with a serious face: "Some people can contribute 30,000 points. The subsidy is because they are only worth 30,000, and I can get the subsidy of 30,000 contribution points because the federal maximum subsidy for special talents is only 30,000."

"..." Su He reminded helplessly: "Everyone who can come to the alien frontline is a hero. Isn't it inappropriate for you to say whether it is worth it or not?"

"Ah? Isn't it appropriate? Then edit this section too, and I'll say it again."

"Stop talking about that. You can't learn from Lao Ji. Lao Ji can rely on his old skills and sell his old skills. Can you?" Su He corrected the topic and asked: "Since those robotic arms, machine tools, photolithography machines and so on can all achieve the same goal." With nanometer-level machining accuracy, what’s the point of a fitter whose manual processing accuracy is only millimeter-level? In addition to the reasons Master Liu just mentioned, Lieutenant Shenmu, do you have anything else to add? Or, to summarize?”

Chen Mu frowned and thought for a while, then looked at the camera seriously and spoke out.

"Everything that exists is reasonable. There is a fine turner in three years and a bad fitter in ten years. The existence of a fitter must be reasonable and there is a certain demand. What Master Liu said is the meaning of the existence of a fitter. And when it comes to people like Lao Ji The level of an eighth-level fitter can even be called the god of craftsmanship. Yes, in terms of processing accuracy, it is impossible for Laoji to compare with nano-level machine tools and robotic arms, but processing accuracy is only one of the criteria for judgment. It is an important But it is not all. Because there are only 0 and 1 in front of the machine, and what we need is not only 0 and 1, but also the judgment of an eighth-level fitter that goes beyond 0 and 1."

Su He didn't expect Chen Mu to say these words. Although there were some flaws, they were already very good, so he asked, "What else?"

Chen Mu searched his intestines and scratched his stomach, and his forehead was sweating before he choked out another sentence: "Level 8 fitters can build nanoscale machine tools and robotic arms, but nanoscale machine tools and robotic arms cannot create level 8 fitters."

When Su He gave a thumbs up, the damaged mecha parts had been brought over. Ji Xinghe stood up next to Xinxin and started to put on the work clothes that he had brought over at the same time. Xinxin trotted to Shen Mu and Su He and stood beside him. Outside the operating range, he turned around and raised his fist towards Ji Xinghe.

"Grandpa, come on."

After this sound, the No. 109 operating section entered working status again. No one went to see Ji Xinghe's repair work. Master Liu and others had already wasted a lot of time.

Time passed little by little, but it seemed like there was no progress on Ji Xinghe's side. It was almost time for everyone to get off work, and the lieutenant colonel officer had also appeared nearby. Shen Mu raised his feet anxiously. , he wanted to enter the operating range again and give Ji Xinghe guidance.

But as soon as he took a step, the hem of his shirt was pulled hard by a small hand. He turned around and saw Xinxin with a serious expression on his face. She looked at him with firm eyes and shook her little head from side to side very hard. , as if she were using this behavior to express her attitude.

"Uncle, my grandpa said you can't help him all the time. You have your own work, responsibilities and obligations, and my grandpa must also have them."

Chen Mu was stunned. It had been a long time since Xinxin left Ji Xinghe. She actually still remembered Ji Xinghe's instructions and executed them flawlessly?

There is something about this kid, is he a genius?

At this moment, Ji Xinghe's calm voice suddenly sounded in the No. 109 operating range.

"I've fixed it. Master Liu, you can check it out and wait a while. I'm not in a hurry."

Master Liu and others had not yet reacted. When they looked at Ji Xinghe in astonishment, Shen Mu became anxious.

"Old Ji, you are serious, the child hasn't eaten yet, you are not anxious, can the child not be anxious? Hurry, Master Liu, please take some time, if you really don't have time, I can come over, I will test it. "

"Didn't you eat?" Ji Xinghe's expression suddenly changed to one of shock, and then he was full of annoyance and panic: "I'm sorry, Xinxin, grandpa forgets time when he is working. Come on, grandpa will take you to eat."

"Xinxin is not hungry. Grandpa has worked hard."

When Xinxin spoke out, Ji Xinghe had already quickly stepped out of the operating area, took her hand, and then led her slowly outside.

Everyone else was stunned. Su He's mission was to follow Ji Xinghe, but he felt that the inspection of the parts was also very important and wanted to stay and shoot, so he was hesitant. Chen Mu shouted directly: "Old Ji, wait. Yes, this is very urgent. Didn't you just hit someone? Why are you leaving so easily now?"

Ji Xinghe didn't look back and didn't care about Shen Mu Wuxin's slander. He held Xinxin with his right hand and raised his left hand and waved it twice behind him.

"I've fixed it."

He said that he had fixed it, and left with his granddaughter without looking back, not only because he was very confident, but also because he felt that it was more important for his granddaughter to eat on time. Only by eating on time can she have good health. He brought the kitchen knife at home with him. He went to steal a single-soldier starship and wanted to go to an alien planet to die, but after finally arriving on the alien planet, he stayed in an underground base. Isn't it just so that his granddaughter can take good care of her body?
