Mecha and Knife

"stop."

Ji Xinghe led Xinxin and stood behind Shen Mu, and when Shen Mu's fingers were about to turn up again, he said, "That's it."

Shen Mu's finger stayed on the third-to-last item in the list of requirements in the No. 109 operation area: a maintenance item requirement. The estimated completion time of the system is 864 hours. The hour here is the time unit of the blue star. The sunrise and sunset on the alien star are completely different from the blue star. A day is not twenty-four hours, but it doesn’t really matter, because everyone basically lives in the underground base. Can see the sun.

Although this time is not the time for the artificial intelligence program of the base to combine advanced technological creations such as robotic arms and machine tools to repair needed parts, it is only because the relevant resources are allocated according to the priority, and the 864 hours are almost all waiting in line. 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 had pricked up his ears, and suddenly felt a little regretful that he had pretended to be a coward just now, but he pretended to be a coward, even when he was kneeling.

"As I said, the reason why I am an eighth-level fitter is because the highest level of fitter is only eighth."

Ji Xinghe actually has a way to retreat now. The advantage of being old is that if he admits defeat now and repairs the car, no one will really trouble him. But he wants to let himself have no way to retreat, because life is like this, if you take a step back, you will completely lose the possibility of going further. You may have new opportunities when you are young, but Ji Xinghe is really not young anymore. Others call him It's a matter of course when you are old.

"Okay, okay, just be stubborn."

Shen Mu complained a little, but he still explained some key knowledge points to Ji Xinghe at the first time. As a second lieutenant-level expert mechanic, he knew all the standard mechas of the Federation and all their parts. Shen Mu came to help choose the reason.

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. Shen Mu also told him all the information that could not be seen because of the confidentiality level.

Can do it.

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

Master Liu, who felt that he was about to be touched just now, dared not 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. He has spares here.

"Fix it, let's fix it. If it's broken, you don't need your contribution points. Anyway, we don't have time to repair it. Now the queue time is more than 800 hours. In a few days, it may be more than 800 hours. There will be more than 800 hours according to the priorities. When the queue-jumping situation happened, our original plan was to wait, and we couldn’t wait to replace the parts without repairing it.”

Master Liu looked at Ji Xinghe, who was of the same generation as his grandfather, and suddenly sighed while talking, "Mr. Ji, I am really not embarrassing you. I am really short of eighth-level fitters. All the operating sections here are lacking. Other bases The situation is the same. But your age... we dare not gamble, because if you lose, you will die."

Ji Xinghe was relieved to see someone going to the warehouse area to pick up the damaged mecha parts.

"Master Liu, I'm sorry that I was too excited just now, I can understand you, I'm sorry, but I really need this opportunity, I will not 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 will be working hard in a while and has no time to take care of Xinxin. .

Shen Mu and Su He backed away tactfully. Shen Mu originally wanted to emphasize some key points, but was actually pulled away by Su He. The two stood outside the line drawn in the No. 109 operating area.

Su He asked curiously in a low voice: "Is the eighth-level fitter very good? How to judge whether the old Ji is good or not? Does it depend on the machining accuracy? Millimeters or 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 three geometric parameters of the machined part surface, the actual size, shape, and position, meet the ideal geometric parameters required by the drawing. The smaller the number, the better. "

"Yes, this is indeed the machining accuracy. Nano is already the limit of our human technology."

"That old man is an eighth-level fitter, can he reach the nano-level?"

"..." Shen Mu, who didn't want to explain this question at first, noticed that Su He's camera was turned on, and thought that he would definitely appear in Ji Xinghe's documentary in the future, so he seriously replied: "No, don't say that Lao Ji is An eighth-level fitter, even if he is the ninth-level fitter he said, the tenth-level fitter will not work. Because the limit of human processing accuracy is only three decimal places of the unit of millimeter. "

"That is to say, it can only achieve a processing accuracy of 0.001 millimeters at most?" Su He said in a daze, "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. Are you older?"

Shen Mu took a deep breath, calmed down the complex emotions facing laymen's low-end problems, and continued to explain seriously: "Not only is the gap between two zeros and five zeros huge, but also the gap between 0.009 and 0.001. Very big...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 a certain time, but I’m talking about my life.”

"you?"

"What's wrong with me?" Shen Mu raised his head and chest up: "I am Shen Mu, the youngest second lieutenant mechanic in the Federation, I just came to Alien Star and received a subsidy of 30,000 contribution points without making any achievements. Do you know why? "

"why?"

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

"..." Su He reminded helplessly: "Everyone who can come to the front line of the alien star is a hero, isn't it a bit inappropriate for you to say whether it is worth it?"

"Ah? Is it inappropriate? Then edit this paragraph too, and I will say it again."

"Don't talk about it, you can't do it if you want to learn from the old man, can you sell the old man?" Su He corrected the topic and asked: "Since those robotic arms, machine tools, lithography machines and so on can reach Nano-level processing accuracy, how much sense is there for a fitter whose manual processing accuracy is only at the millimeter level? Apart from the reasons that Master Liu just said, do you have anything else to add, Second Lieutenant Shen Mu? Or, to sum it up?"

Shen Mu frowned and thought about it, and only after a while did he look at the camera seriously and make a sound.

"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 has certain needs. What Master Liu said is the meaning of the existence of a fitter. And when it comes to Lao Ji The level of the eighth-level fitter can even be called the **** of craftsmen. Yes, in terms of machining accuracy, it is impossible for Lao Ji to compare with nano-level machine tools and robotic arms, but machining accuracy is only one of the criteria for judging, it is an important But 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 eight-level fitter beyond 0 and 1."

Su He didn't expect Shen Mu to say these words. Although there are some flaws, it is already very good, so he asked: "What else?"

Shen Mu scratched his stomach, his forehead was sweating, and then he choked out another sentence: "Eighth-level fitters can make nano-scale machine tools and robotic arms, but nano-scale machine tools and robotic arms cannot make eight-level fitters."

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

"Grandpa, come on."

After the sound, the No. 109 operation area entered into working state 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 there seemed to be no progress on Ji Xinghe's side. It was almost time for everyone to get off work, and the lieutenant colonel officer had appeared nearby, so Shen Mu raised his foot anxiously, He wants to enter the operating range again and point out Ji Xinghe.

But as soon as he took a step, the hem of his jacket was pulled by a small hand, and when he turned his head, he saw Xinxin with a serious expression, looking at him with firm eyes, shaking his little head from side to side with great force , as if using this behavior to express her attitude.

"Uncle, my grandfather said that you can't help him all the time. You have your own work, responsibilities and obligations, and my grandfather should have them too."

Shen Mu was stunned. It had been a long time since Xinxin left Ji Xinghe's side, but she still remembered Ji Xinghe's explanation and carried it out perfectly?

This kid has something, is he a genius?

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

"I've fixed it. UU Reading www.uukanshu.com Master Liu, you have to check it out. It's okay to wait a while. I'm not in a hurry."

Before Master Liu and the others could react, they looked at Ji Xinghe in astonishment, but Shen Mu became anxious.

"Old Ji, you are serious, the child hasn't eaten yet, can you not be in a hurry if you are not in a hurry? Hurry up, Master Liu, please spare some time, if you really don't have time, I will do it, I will test it. "

"Didn't eat?" Ji Xinghe's expression suddenly became astonished, and then he was full of annoyance and panic: "I'm sorry Xinxin, grandpa forgot the time when he was working, go, grandpa will take you to eat."

"Xinxin is not hungry, grandpa has worked hard."

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

Everyone else was stunned. Su He's task 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. Shen Mu directly shouted: "Old Ji, wait a minute, this, this is also very urgent, didn't you want to beat someone just now, why would you just leave as soon as you say so?"

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

"I've fixed it."

He said that he had repaired it, and he took his granddaughter away 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, and to have a healthy body by eating on time. He took a kitchen knife from the kitchen at home to steal a single starship and was about to come to Alien Star to die. After finally coming to Alien Star, he stayed in the underground base. Isn’t it because his granddaughter can take care of her health?

Granddaughter, you need to grow up quickly and grow up healthy, because there is not much time for grandpa to avenge your father.
