The three of them were living in a military compound that was full of vitality in this era. If they said it was a military clothing factory, people would definitely believe it. However, if they said it was a place for scientific research, people would probably laugh their teeth off.
Zhou Li felt Qu Sen and Li Ying's uneasiness. He was angry but didn't know how to explain it. He used the excuse that he was tired and wanted to sleep as he chased Qu Sen out.
Li Ying was very interested in the soldiers working in vests in the winter. When she heard that Zhou Li wanted to sleep, she pulled Qu Sen out to watch the fun. Qu Sen wasn't tired and happily went with her.
The group of soldiers working were digging the pipeline trenches. They were all sweating as they took turns with shovels and shovels. The double-cassette recorder on the mound outside the pit was playing "The Mountains and Rivers Get a New Look".
Listening to the passionate duet between a man and a woman, watching the hoes and shovels rise and fall rhythmically, Qu Sen suddenly had an inexplicable impulse to throw off his clothes and jump down to work with everyone.
Qu Sen suppressed the thought that almost made him laugh. He looked at the segmented construction trenches in front of him that he couldn't see the end of. Thirty meters away, the pipeline had already been set up. Another group of soldiers was burning asphalt and sealing the seams of the pipeline that had already been set up.
Qu Sen looked at the black cable wrapped around a three meter tall wooden roller not far away and subconsciously walked a few steps in that direction.
"Brother, what are you doing?" A soldier in the pit put down his pick and took out a cigarette from his pocket to light it. He saw Qu Sen and Li Ying wearing local winter clothes and asked curiously.
"Oh, we're here to order some things." Qu Sen answered politely. He looked at the unusually thick shoulders of the soldier who spoke. The hot sweat on his body even released wisps of white steam.
"Are you making a tractor plank?" The soldier asked again.
"Ah, something like that." Qu Sen nodded in response.
As the two of them spoke, the soldiers who had been working silently finally noticed the two people dressed in local attire and raised their heads to size them up.
Li Ying's hair had grown long, and her personality had also become shy. She felt a little embarrassed being stared at by a group of people. She tugged at Qu Sen and whispered, "Let's go back."
Qu Sen smiled and nodded to the person who spoke to him. He then followed Li Ying's footsteps and began to walk back.
After the two of them had walked for about ten meters, the soldiers working behind them suddenly said something, causing a burst of laughter. After Li Ying heard this, she reached out to grab Qu Sen's arm and quickened her pace.
"Why do you think this kind of unit needs a 3D printer?" Li Ying whispered to Qu Sen when they were about to reach the guest house.
It wasn't that she didn't believe that a run-down unit wouldn't have the money to buy such advanced equipment. She was just confused as to why a place that only knew how to make tractor planks would want to print something like that.
"Haha, don't worry about that. Maybe they're using it to print tractor models." Qu Sen said with a smile.
"Aren't you curious at all?" Li Ying asked strangely when she saw that Qu Sen didn't seem to care at all.
"I'm curious." Qu Sen mischievously glanced at Li Ying and whispered, "I'm curious as to why a factory that makes tractor parts would use fiber optics!"
When Li Ying heard Qu Sen's words, she subconsciously wanted to turn around to look at the "cable" in the distance.
"Okay, don't look anymore." Qu Sen stopped Li Ying and whispered, "I just walked two steps closer, and they already used words to test us. If you go any closer, we might be held down and have to trouble Zhou Li's father to come and get us. "
"Really?" Li Ying naturally recognized the optical rod, but she subconsciously thought that it was a cable, so she didn't pay much attention to it.
"Don't worry, this factory definitely doesn't only make tractor parts." Qu Sen smiled as he walked through the door of the guest house.
Zhou Li's father finished his work at around ten at night and went to the guest house to see his daughter. Of course, he also wanted to get to know Qu Sen. As for Li Ying, she went to Zhou Li's house to play when she was in university.
Zhou Li's father was very tall, but he was very thin and his complexion wasn't very good. He had a waxy yellow complexion and it was obvious that he often stayed up late. He was wearing a pair of winter trousers, which clanked loudly. He was very easy-going when he spoke.
After Zhou Li introduced the two of them to each other, Old Zhou said a few words and directly picked up Qu Sen's cigarette box on the TV cabinet. After taking out a cigarette and lighting it, he took a deep breath and said with his last breath, "I've been suffocated to death today."
Qu Sen wanted to laugh, but he was too embarrassed to do so. He tried to find something to say, "Uncle Zhou, your workplace doesn't even have a smoking room?"
"Smoking room? I can't even bring a lighter in." Zhou Li's father complained with his last breath and then reminded Qu Sen, "Oh right, when you go to the design building tomorrow, leave the cigarettes and lighter in the guest house."
"Yes, I'll remember." Qu Sen heard that the requirements were so strict, so he quickly responded.
"Relax, it's just a normal rule. It's not that serious." Zhou Li's father smiled and said, "Did you guys eat dinner? I'll take you to the small cafeteria to eat more. "
"No need, Dad. You should go back and rest." Zhou Li saw that his father's expression was very bad, so he couldn't help but urge him.
"Okay, I'll go back and sleep. I'll have someone pick you guys up tomorrow morning after breakfast. Bring the recommendation letter from the school and prepare the parameters of the grinding tools. "Zhou Li's father was indeed tired, so he left after giving a few words of advice.
The next day, before the breakfast signal rang, the driver who picked them up yesterday came again. He took the three of them to the cafeteria for breakfast and then led them to the design building.
The so-called design building was a half-new five-story cement building. The biggest difference between it and the other buildings around it was that it had aluminum alloy windows and a few rooms had air conditioners outside the windows.
The three of them didn't pay much attention to it at first, but when they entered the building, they found that it was different. As soon as they entered the building, they had to go through a security gate similar to the one at the airport or train station. Then, the soldiers on duty carefully checked their IDs and recommendation letters. After checking the registration book, they used the walkie-talkie to inform the people inside.
The reason why they had to be informed was because the three of them were facing an automatic door made of thick frosted glass. After the two electric doors opened, the scene in front of them finally overlapped with the advanced scientific research institute in Qu Sen's mind.
There were bright lights above their heads, white walls in front of them, and the light-colored tiles under their feet were spotless. They could basically be used as mirrors.
After the security guard checked their IDs again, he guided them to the third floor. When the three of them came out of the elevator, the elevator next door just opened. When he saw Zhou Li's father walk out of the elevator, Qu Sen's psychological pressure caused by the environment eased a little.
Looking at Zhou Li and Li Ying next to him, Qu Sen realized that the two girls were in the same situation as him. They were more or less a little nervous.
"Dad, you're just making a broken tractor part. Do you have to make such a big fuss?" Zhou Li heard Li Ying talk about her experience with Qu Sen last night. She couldn't help but say this to her dad.
"So what if it's a tractor? A tank is a tractor. Do you think it can be made anywhere?" Zhou Li's dad said with a smile as he led the three of them to a room at the end of the corridor.
Not long after they pressed the doorbell, the door opened from the inside. A female researcher in a white coat smiled and said, "Hello, chief engineer." She let the four of them into the room.
Qu Sen had never seen a 3D printer before, so he thought it was something high-end. However, when he looked at it, it was a large cabinet with a transparent glass door. If he didn't look at the spray parts inside, he would have thought it was a cold display cabinet.
Zhou Li's dad had already communicated with the technician in charge of the 3D printer. After sending the three of them here and confirming that the machine was free, he went back to work.
The technician in charge of the 3D printer was surnamed Shao. He had a very good attitude towards Qu Sen and the other two. After asking in detail about the requirements of the parts to be printed, he recommended a few printing consumables.
Qu Sen and the other two really didn't know anything about the special consumables of the 3D printer. They could only say that the material had to be as light as possible while ensuring the strength of the material. In addition, the blade had to have a certain degree of rigidity and good toughness.
According to these requirements, the operator separately introduced two types of synthetic consumables for the blade and the fuselage.
The three of them had no idea about the complicated composition of the consumables. They could only choose to trust the professional's recommendation.
After confirming the consumables, Technician Shao reported the price of the consumables. The machine didn't cost money, but the consumables research institute wouldn't pay for the school.
Moreover, because of the composite consumables, they needed to use several base materials at the same time. Three of the base materials would lose their activity if they weren't used for a period of time after they were opened. Therefore, no matter how much these three consumables were used, they had to be packaged and bought.
