Yu Jianguo stayed in the laboratory, and at the beginning was nothing. In his impression, one or two security guards are always needed at the door of a building to receive visitors and arrange parking. But everything here is already in order, and it seems a lot of him to intervene in it, and he can't operate those fully automatic equipment, as well as electronic screens and cameras that can "talk" in a hurry.

He went to do sanitation. He swept the ground secretly for a few days. Why secretly? Because he was embarrassed to say that he swept the floor, the floor here is too clean, cleaner than any place he has seen, the only difference is probably the operating room in the hospital, oh, and the morgue.

Later, he learned that there was a very advanced purification system in the building that hardly left any dust, and there was also a sweeping robot, which had already cleaned the floor before he took the broom to clean, and even the garbage was automatically cleaned up. If you go out, you don't need anyone to do it.

He felt very embarrassed. He had lived a long time and had seen the world before, but he was even confused when he was playing miscellaneous things.

He didn't know if the professors upstairs knew what he was confused about. Anyway, the talking cameras must have seen it. Will these guys report to them? Old Yu often thinks this way, and secretly tells them: "I don't know how to do things, you know a lot, and you have time to teach me."

The camera stared at him, not moving or talking. Lao Yu said: "Look at you, I sincerely ask for advice, why are you silent again?"

No one teaches, and is old at sweeping perseveringly. He said, I'm a big living person, I can't sweep you a robot crawler by sweeping the floor?

He bought the broom by himself in a nearby supermarket, and he did not find the broom in the laboratory. Later, he threw the broom secretly again, because after several sweeps, the broom was not clean in the building.

Instead of using a broom, he wiped it with a rag. Not only did he wipe the floor, he also wiped the walls and the sculptures and furnishings in the building. The robots never clean these things. Sometimes, he also wiped the eyes of those talking cameras, and smiled when he wiped the eyes, and said, "You wear a lens so thick, how nearsighted is this?"

A few days later, the young and beautiful professor assistant girl came to Lao Yu and said that she would train him. Old Yu began to receive training, what kind of equipment is this, what is this for, and how to maintain this. Lao Yu was ignorant, and the training lasted for two or three months intermittently. The people who trained him were all upstairs. They all liked Lao Yu, and Lao Yu liked them.

For example, the young man named Bian Ziyuan is very good at talking, and in private, I invite Lao Yu to eat hot pot. Lao Yu likes the young man's temper very much, serious, stubborn, and vigorous, but he is not the kind of one who wants to spend money all the time. Old Yu knows that it is called an ideal—a thing that has been lost in him for a long time, a thing that can make people excited, a thing worth cherishing but easily abandoned by reality.

Old Yu admires young people very much, young is good, young is worthy of ideals. But he admired Professor Mei even more-his hair was whiter than him, but he was more agitated than young people when he was learning, and he had fighting spirit.

In such an environment, Lao Yu also became more aggressive, as if he had returned to his youth.

He couldn't help but think of Zhao Pengcheng again. What a nice boy! Pity……

After passing the training, Lao Yu signed a contract, handed in social security, and became a regular employee of Mei's laboratory.

He now also knows how to perform identity authentication in front of electronic screens and cameras, how to press fingerprints, how to iris, and how to verify genes. He was also allowed to go upstairs and basement freely to do what he was supposed to do. Of course, he has to apply for some places to go, and the top floor can't go anyway. The access control there is very strict, and only a few people can go in.

Before she left, Mei Ziqing handed a key to Lao Yu and said, "Uncle Yu, this is an emergency key. You should keep it safe."

Yu Jianguo asked: "Which door does this key open?"

Mei Ziqing said: "It's for emergency use. There are two keys in total. They need to be used together. If you encounter an emergency, you should contact us. When you need the key, I will tell you."

Yu Jianguo asked again: "Who is the other one?"

Mei Ziqing said: "The other one is under the control of the professor. I don't know who I gave it. You can't tell anyone that I gave you the key. This is the rule of the laboratory."

"Oh, the rules, I understand the rules." Yu Jianguo nodded and accepted the heavy key, feeling the burden on his shoulders heavier again.

He wandered around in the empty laboratory alone, turning east and west, looking here, looking there, these are all familiar to him, those places he can’t get in and can’t see. Don't watch too much.

He felt that he was left alone now, and if something happened, it would be his responsibility, so he couldn't be careful. Don't let the thief in! Not to mention the thief, not even an ant can climb in.

After turning for a long time, he thought again, which door was the key that the young assistant professor gave him? Since it is an emergency key, there is always a place to open it, and since it was handed over to him, it is always a place where he can go ~lightnovelpub.net~ but he didn't see where the keyhole can be inserted. The doors here are all Automatic, there are identification devices in front of the door, and the door opens as soon as it clicks.

Bian Ziyuan came back suddenly while he was groping.

With a big bag in his hand, Bian Ziyuan passed the security check of the gate and entered the hall. Yu Jianguo saw it and quickly greeted him:

"Oh, Teacher Xiaobian, didn't you go home for the New Year, why are you back again?"

Bian Ziyuan said: "I found an important data error at home, I need to come back and correct it."

"I still specialize in research work during the holiday, so dedicated! No wonder you are so good at a young age!" Yu Jianguo stood in awe and reached out to help Bian Ziyuan carry his bag. "I used to have a nephew who worked as hard as you when I was young."

"Hey, Uncle Yu, you can put it down, I'll carry it myself, this bag is not heavy." Bian Ziyuan said while changing his shoes, "Your nephew also works on computers?"

"Oh, he's a doctor." Yu Jianguo took a bag and found it was not heavy, so he let it go.

Bian Ziyuan changed his shoes, stood in front of the dust collector, removed the ashes on his body, put the bag in the dust bag, and then carried it into the elevator:

"Uncle Yu, you are busy, I'll go up first!"

Yu Jianguo responded "Hey" and saw the elevator door closed. He walked slowly to the monitoring room. On one of the screens, he happened to see the side far out from the elevator and immediately appeared in the corridor on the other screen. Then he stood in front of a door for a while. opened.

Bian Ziyuan walked in and the door closed.

There was no monitoring inside the door, and even if there was, Yu Jianguo knew that he could not see it.

He left the monitoring room and strolled around again and again. After walking for half a circle, I heard the elevator ding and Bian Ziyuan came out again. I saw Yu Jianguo and asked:

"Uncle Yu, do you have an emergency key?"
