"Most people in research institutions are meticulous. Even if they occasionally meet a few scientists with strange personalities, most of the habits they have developed in the laboratory for a long time make it easier for them to remember and abide by various 'rules' than ordinary people. If they are always careless and not paying attention to anything, those people may not be able to stay in the laboratory for a long time and break this and that, and luck may almost have to hurt themselves."

Yiwen tried to accidentally knock down a container in the laboratory of Super Ringyin, and the liquid spilled out of it instantly created a bottomless hole in the floor of the Institute, which was claimed to be able to withstand nuclear strikes. If Yiwen had a little luck at that time, she would have been a little bit weak and let the liquid splash on her body, even if she had the immortal body of vampire talent, she would have been very painful, which would have made Levi feel distressed.

"Well, there are also people who were seriously injured and admitted to the hospital due to negligence. I have heard from the director before."

Khan, I didn’t expect that people like Yiwen were indeed in another world, but that person did not have the same immortal body as Yiwen. Almost everything in the laboratory can be used as a tool for murder when used slightly. If you don’t follow the laboratory’s rules, it’s not much different from chronic sudden suicide.

"...so people who often go to and from laboratories will pay special attention to abiding by various regulations, such as the sign that you read the words written on it. But how many ordinary people who live in a peaceful world will be so meticulous at all times? Especially the people of developed countries on the earth are increasingly pursuing the quality of life and paying attention to the joy of life, so that they can be careful about this and that life every day. Even if they walk a staircase, they have to look up first. How can they bear it?"

“So that’s it, so for those who are not careful, it’s necessary to design devices that don’t matter even if they forget to close the door?”

It seems that although Tio rarely goes out and rarely comes into contact with people outside the small circle around her, the "common sense" in her mind is obviously much more than some girls around Levi. As long as she slightly corrects her wrong direction, she can immediately get the key points.

"Yes, the device you mentioned is the door closeter on the top of the door."

"Door Closer?"

Hearing Levi say this, Teo raised his head and stared at the top, where there was something like a curved metal strip that had already made her care a little before. She tried to push the door a little and then retract it, and found that it was actually two metals fixed with things at the intersection.

"There is a hydraulic inside the door closer on the top of the door frame... Do you know the hydraulics? They are something like springs."

Tio nodded and said that she knew that she hadn't spoken, making people confused whether it was her own world that had it or what she learned after coming to Earth.

"After the door is opened, the door closer will start working and generate a pulling force. When you let go, the door will be pulled back and closed by the door closer, and then locked. Although this will make the door sink a little, at least as long as the door closer is not broken, it can ensure that the door will be closed every time it is pushed open. In case of a fire, the fire will burn the entire building directly."

"I see."

Teo finally showed a satisfied expression. Although the changes on her face were as subtle as Eve. But Levi was a man who could see through even Yuxi's face that claimed to be without expression. This girl was just a little cold, so how could she hide it from the warriors who had been through many battles?

Levi was relieved to be satisfied with her. Instead of wasting more time, it would be better to explain it in detail and save time and effort.

Look, it's a long way to speak, but Levi's speaking speed is not as slow as a snail. Hasn't it been only two minutes?

Teo was a little happy about learning something new, but she naturally would not forget her original intention of letting Levi bring her here. She was not a student who came to conduct popular science teaching in school, but a search officer (self-proclaimed) who went to the mysterious institute and processing factory to investigate secretly. She pulled Levi's coat and pushed him gently, which meant that he could continue to lead the way. Levi immediately understood it and tried not to make too loud noises and start going down the stairs without affecting the speed.

We had already made a plan to go to the production workshop on the bottom floor to see what the final output of this building was, so on the way down the stairs, both Levi and Teo did not open the fire door on each floor, which was as red as the top floor. They were walking on the fire stairs. In order to evacuate the crowd as quickly as possible during the fire, they would naturally not make twists and turns waste time and increase the distance. The two of them turned around in circles and went down. Not long after, they reached the end of the stairs. The right side of the door frame was painted and sprayed on the wall, telling them that this was the first floor of the building.

“No basement?”

The stairs did not extend further down here. Teo was curious and poked the ground with the magician in his hand twice, with a dull echo as if nodding to answer her question.

"That's not necessarily."

Levi put half of his body and ears on the door to try to hear something special outside, and answered Teo's questions casually. He thought that this girl probably lived underground for a long time, so he took it for granted that she would open up spaces underground. But this guess is true, especially in modern cities like Academy City, which emphasizes science, rationality, and maximizes everything. There are basically few buildings without basements. Even in places such as residential areas where underground warehouses are not needed, there will be underground parking lots designed to save space. The same is true for the building they are staying in now.

At the beginning, the drawing of Tio showed that there was an underground part specially used for parking vehicles and unloading and loading. On the one hand, it was like residential buildings and office buildings to save space. On the other hand, it was probably considered that some factories might produce things that needed to avoid light and try not to contact dust. Although they would definitely pack them before transportation and set the loading location under the ground where there was no wind or sun, it was also considered an additional layer of guarantee. Does anyone think it was too safe and felt that it was not irritating? At least the people in the factory and the scientists in the institute were probably not so idiotic, and they would have nothing to do.

"The purpose of this staircase is to facilitate people to escape as soon as possible when disasters occur. If there is still a way to underground when you get here, wouldn't it be easy for people who are fleeing to get the wrong direction? Think about it, the fire behind them is chasing or the house is about to collapse at any time. In this case, people who are desperately trying to run out have the time to tell which road leads to? There is a saying on earth that is called "Pussy and unstoppable" means this."
