"Why didn't Makuba come to work today?" Tianming, who was sitting at the dinner table, asked Lan Luodao.

Sandwiched a green vegetable into his bowl, Lan Luo ate two bites of the meal and said, "Why does she revolve around you every day?" We have one day off every week. ”

Although Lan Luo and Makuye are Tianming's assistants, they have a day off every week, and Lan Luo is off on Saturday, so Makuye will be off on Sunday. In the past, they were next to Tianming almost every day, but after the New Year, Makuba seemed to have something going on, and every Sunday, they would go out happily, and they would no longer work overtime by Tianming's side every day like before.

Seeing that she looks a little happy every time she has a holiday, does she have a sweetheart? Tianming guessed.

"Then why don't you go to rest?" Tianming asked rhetorically.

"I like to work overtime, can't I?"

There's overtime pay for this guy who accompanies you. Lan Luo thought.

"Yes, yes, but every day I see someone in front of me, I can't keep my spirits up." Tianming sighed.

"Ahh You dare to call me annoying?! I'm not done with you! ”

Putting down the dishes and chopsticks, Lan Luo chased after Tianming.

After a while, the bell rang, the communication instrument rang, and the call came, Secretary He called.

"What's the matter?" Tianming asked casually.

"Xiao Xu, hurry up and get ready! Change into a formal outfit and want to see you! Secretary He said in a hurried tone.

"Long? That long? ”

"Captain No. 1, I'll send a car to pick you up right away!"

Lan Luo, who heard the voice next to her, also reacted, and her expression immediately became stern, she took the clothes from Tianming's bedroom, immediately put them on for Tianming, and then helped him tidy up his collar and shape it quickly. A young man who loves five generals, four beauties and three loves appeared.

Phew! Where was a car parked at the door, Lan Luo immediately pulled Tianming into the car.

……

Along the way, I saw a lot of soldiers with loaded guns guarding the entrances of various passages, and checking documents was more frequent and careful, and it used to take 1o minutes to walk, but now it takes 2o minutes.

When I came to the door, there were many fewer soldiers, but there were many more plainclothes in suits and leather collars.

With a nervous mood, Tianming walked into this lounge under the leadership of Secretary He, who had been waiting at the door for a long time.

"Long. I brought Xiao Xu here. ”

Inside the house, several people sitting on the sand, drinking tea around a glass tea table, turned their heads at the same time, and after seeing the appearance of one of them, Tianming immediately stood unsteadily, and his heart beat wildly and felt like he was about to jump out. x big, it's x big!

I'm dreaming, this must be dreaming!

The man came over on his own initiative. Holding Tianming's hand, he smiled and said, "You are Xiaoxu, I have been looking up for a long time, I have wanted to see you for a long time." ”

“x…… X big, really, really, is it really you? Am I not mistaken? Tianming rubbed his eyes. Look at him and say.

Held by his warm and rough hand, and looking at his approachable smiling face, it is the same as on TV, but more intimate and real! Like his own father and elder brother. There is not the slightest sense of distance.

"You read that right, I'm the X big on TV." Pull Tianming to a nearby sand, "Come on, come on." Xiaoxu, let's sit down and talk slowly. ”

"Oh, oh!" Tianming clumsily did it on the sand.

In his bones, Tianming is still an ordinary otaku, although he has a lot to say, but he can't open his mouth, so he can only sit next to him with a dizzy head.

In addition to Commander Xu in the base, No. 1 Commander X Da, Minister of Industry Li Yizhong, Director of the General Assembly Design Department Zhang Zhaoxu, Deputy Director of the Military Commission Fan Baolong, there are a total of so many people in the entire lounge. But each of them is an important leader of the country, and the main purpose of their coming to this 3oo meter underground base today is not only to inspect the results of the work of the six shields of national defense during this time, but also to meet the so-called supernatural ones.

A few people talked and laughed for a while, and during this time, they also asked Tianming a few questions, how old is it, where is his hometown, etc.? He replied in a panic, and said that 28 was 18 years old, and everyone laughed, and X Da joked that he was more like 16 years old, and made Tianming's face look like a red apple.

The distance is invisible, but it has been shortened a lot, and Tianming is not so restrained.

Xu Guoyuan stood up and said, "Chief, can we go to inspect?" ”

"Okay, I'm almost done, take me to your base to have a look." He also said to Tianming: "Xiaoxu, let's go, let's go and have a look!" ”

"Good!" Tianming quickly got up, followed by the chief, and Commander Xu, one old and one young, gathered next to him, got on a battery car, and came to visit various departments and research institutes of the base.

Every time I went to a department, the staff of that department would keep cheering, and the palms of their hands would turn red, leaving tears of excitement. Every time I go to an institute, the researchers there will show their research results to the long-term, and there will be professional docents to answer questions. Sometimes, the chief will take the product in his hand, observe it carefully, and ask a few questions, and when he learns that this product is very advanced, even more advanced than abroad, he will say to the people next to him: "Thank you comrades for researching such a good thing, the country thanks you, comrades have worked hard!" ”

At the Cyber Shield Bureau, the chief is very interested in virtual games, he puts on a virtual helmet, and in World at War, he kills three soldiers without a single bullet falling around him, and he angrily says that he will not play. Ye Xiaobai introduced his "Daily Parkour" adapted from a mobile game to Chang, and among the last 6 people, Tianming ran 63oo meters to win the first, and long-distance ran 32ooo meters to win the second, and sighed again and again that he was old and couldn't compare to young people.

When he came to the machine tool design institute that he attaches the most importance to the implementation of the "Mother of Industry Plan", he walked into a spacious workshop and saw that one after another industrial machine tools were being debugged and installed.

Next to a machine tool that has been debugged, the technician next to him asked: "What is the machining accuracy of this five-link five-axis machining machine?" ”

"1 nanometer." The technician was very sure.

Chang was stunned for a moment, and asked in disbelief: "1... 1 nanometer, is there really 1 nanometer? ”

"Really, the ruler used on this machine tool is by far the most accurate in our country and even in the world, according to these rulers, and some instruments. We can achieve an error of less than 1 nanometer! The technician said confidently.

"Good! Good! Good! Changlian said three good times, excitedly put his hand on the platform working surface of this machine tool, immediately retracted his hand again, and nervously asked the technician next to him: "I touched it, it will not affect the accuracy of this machine tool, right?" ”

"No, no, no." The corners of the technician's eyes became hot.

Everyone came to a large 3D printer and asked how the printer worked.

Wan Cong, director of the machine tool design institute, said to a young man next to him: "Third brother, tell the chief about how this machine works." ”

"Third brother?" There was some confusion on the long face.

A young technician next to him explained: "Chief, we all call him 'Third Brother', which means 'Third Brother' for 3D printing. He, in addition to eating, even sleeping has to be next to this machine, he is obsessed, and his name of 'third brother' is called like this. ”

"Oh~" became interested and asked, "Then who are the eldest brother and second brother?" ”

The third brother looked at the 3D printer next to him and replied embarrassedly: "The second brother is my wife at home, and the eldest brother is this machine." ”

"Hahahaha!" Everyone laughed, and Chang even joked: "You treat this machine as a big brother." If your second brother goes home and gets jealous and punishes you for kneeling on the washboard, what will you do? ”

"The third brother said, if the second brother dares not to want him, he will use the eldest brother to print another second brother out." The technician next to him stood up and coaxed.

"Hahahaha!" The crowd burst into laughter.

The third brother kept scratching his head in embarrassment. Explaining the working principle of this machine, when he asked how fine the things printed out by this machine can be, the third brother said: "It's about 12 microns, mainly because the nozzle of the nozzle can only be adjusted to this time." The powder material couldn't be finer. But Lao Wan said that he wanted to improve the accuracy to 1o nanometers, and I felt that this was difficult. ”

1o nanometers, the diameter size of 1oo atoms. There didn't seem to be a problem with Tianming, he stood up and said to the third brother: "Can you take off that nozzle, I can process it for you, and 1o nanometers will be able to do it immediately." ”

"You are?" The third brother looked at Tianming suspiciously.

The eyes of the few people next to him lit up, especially Chang, and the sense of anticipation was immediately pulled up by him. Commander Xu took off the nozzle of the 3D printer and handed it to Tianming, and then a crack opened, and under the silent gaze of hundreds of people, Tianming made a brand new nozzle according to the request of the third brother, who was already incoherent.

The nozzle was installed for testing, but it ended in failure, because the powder material was too coarse, stuck on the nozzle could not be sprayed, Tianming had to take out the plastic powder in the "ink cartridge", put it into the ability space to "crush", and the printing continued.

"Start printing!"

The squeak machine sounded for a while, less than 1o minutes, a 1:1oo size long full-body portrait was printed, the third brother measured the accuracy with a precision meter, and said excitedly: "Long, according to the surface roughness measurement, the processing accuracy of this statue has reached 8 microns, although it is not up to 1o nanometers of high precision, but it is also a lot of progress!" ”

The accuracy of the 3D printer is determined by the fact that in addition to the printhead, it is also related to the software and hardware of the various components of the entire instrument, from 12 microns to 8 microns, and only one printhead has achieved a 5O% progress.

Director Wan also said: "A printer has more than 1ooo parts, and the accuracy of each part is improved by 4 microns, and the goal of 1o nanometers can be achieved quickly." ”

"Good, good! I'll take this statue back, and when I come back next year, you will help me print a 1o nanometer precision one, do you have any confidence? ”

"Yes!" After everyone finished shouting, Qi Qi looked at Tianming.

"Xiaoxu, do you have confidence?" The long turned to him and asked.

"Chief, there is!" Tianming straightened up and replied loudly.

"Good! Good! ”

……

After the day's inspection, the chief only stayed in the base for one night, and the chief, who lived in the next room B-1O1, specially pulled Tianming to his room, and in a room where no one else was present, the two talked for a long time.

On this night, no one knew what they were talking about, but the significance of the heavy dà produced should not be underestimated. It could even be described in a history book with a whole page! Since this night, country H has undergone earth-shaking changes, and a never-ending power has emerged in the world.
