"It feels like the center of this building?"

Levi's sense of direction tells him that the door is indeed at the center of the entire building without any accident, provided that his sense of direction is not a big problem, and he is not a natural road fool.

"That's right, in addition to this place, there are eight stairs like here, each in front, back, left and right positions, and in the four corners of this building."

Tio raised his phone so that Levi could see the screen clearly, and then replied by pointing to the map above.

"Oh, that's right. Seeing the location of this staircase, I thought this building was just like this fire escape passage."

Even though the girl from another world has learned a lot of knowledge about this world through the Internet, even if she is a genius who can never forget her, it is impossible for her to make up for the gap accumulated over ten years with other peers on the earth in such a short time. Moreover, the girl from another world does not understand. I believe that most young people on the earth also do not understand what Levi means. After all, architecture is like electronic products, built for people to use. The people who use it only need to know how to operate it, without even the construction methods and various principles in their minds.

"This is because buildings must comply with fire protection regulations when designing, especially for houses rented to others, which must be fully compliant with regulations. Otherwise, after construction, they will not be certified by the fire department and will not have the qualifications to rent to others at all."

Levi knocked on the door that was as red as it was removed from the fire truck with his finger, making a dull sound like the one that was removed from the fire truck. It can be seen that the door is quite thick and can indeed have a good effect of blocking flames and smoke.

"Fire stairs and fire passages are not allowed to be placed anywhere they are convenient. The fire department stipulates that each fire protection zone must have at least two fire passages. If this building has just one staircase, it will definitely be impossible to pass the customs at the fire department."

In fact, except when it was just built, the fire department will routinely send people to the building for fire safety inspections every year. Once it is found that there is something that does not meet the safety regulations, it will immediately ask for rectification. The fire inspection of No. 2 Middle School this year was before the beginning of autumn. The people who accompanied the firefighters to inspect were Levi, otherwise he would not have happened to know so much. After all, almost everyone who is familiar with it knows how bad this guy has. Maybe you are asking him this time next year and he will forget about half of what he said to Teo now.

"But what I'm talking about is the regulations of the Central District. The technology in the Academy City is so developed, or there may be more advanced prevention and escape methods. But just by looking at the many stairs in this building, I'm still very careful."

"I see."

After listening, Tio gently pulled the small braids hanging down from her cheeks. Even though this knowledge seemed unlikely to come in handy for her in the future, she listened carefully word by word. This cautiousness made Levi nod secretly. In any case, if a child is so serious, he will accumulate enough experience in the future, no one dares to underestimate it. Compared to the child who is too confident and too high in his talent, Levi is more optimistic about Teo.

Of course, that was based only on the fact that Ling and Tio seemed to be two years apart but felt like a child who hadn't grown up. If the naughty child who wore a puffy skirt and made trouble all day could suddenly enter the sentimental girl stage one day, it would be unimaginable what would be like in the future. After all, that was a typical high-IQ criminal who had just been in contact with Levi and Al felt very difficult and could not miss the water.

‘Please’, Levi’s expectant gaze for Tiotuo was naturally the hope that she could lead Ling on the right path before she grew up to be a little devil who could no one control her, and teach her more about Tiotu’s calmness and seriousness. Who made them live together in another world, and give people the feeling of being the same as the closest little sister?

Of course, Tio could not understand what Levi meant. After all, his thinking was too jumpy. Tio was still thinking about various different parts of this world from his hometown. How could he guess that at this time he would inexplicably think of the little pig sleeping heavily on the bed at home?

Levi put his hand on the door handle and twisted it gently, and the unlocking was extremely small. If it weren't for the fact that both of them had their ears more skillful than puppies, no one could hear them.

“Is this door heavy?”

After the door was pushed open, Teo did not follow Levi immediately. She curiously lowered her head and looked at the door that was a little dazzling under the fluorescent light. Just now, she obviously felt that Levi used some force when she pushed the door open. If it was a normal door, a man with a figure like Levi should push it open without any effort. Even if he is not a warrior with special abilities but just an ordinary person, that should be the case.

Tio couldn't see how special the material of the door was. She was thinking in her heart whether this door was the opposite of the magic weapon in her hand that looked heavy and was actually okay. The material was a specialty of the earth that looked ordinary and actually heavy. The world where Tio grew up did not have such a material. This unexpected discovery inevitably made the girl, who was a researcher, a little bit of curiosity.

"Uh, you ask about this door?"

Levi turned around and saw Teo bent down and knees, hoping that she could have a magnifying glass on her hand and staring at the red door panel. She couldn't help but wonder what she was doing. Fortunately, Teo didn't like to play indirect tricks like some girls. The straightforward questions made Levi realize it after half a second.

"This door has to block the flames and smoke when the fire occurs, and the materials used are indeed thicker than ordinary doors.

But the weight is just a little heavy, making you feel that it is heavy because of the device on top."

Hearing Levi say "head up", Teo raised her head and moved her eyes upwards. As a result, she was too curious and didn't notice that Levi let her hands open for demonstration when she spoke, and the door automatically rebounded and hit Teo's chin.

"It hurts so much."

"Oh, I'm sorry, I thought you were staring at me!"

Hearing the sound, Levi quickly opened the door again, and saw the girl behind the door looking at him with a resentful look, and stroked a small red chin with her left hand. The speed of the door rebounding was not fast at all, but the girl's skin was so delicate that it would break like a work of art. Levi bowed and nodded embarrassedly. Although he knew that this little thing was not even a injury, girls sometimes regard their skin more important than life, especially on their faces. How many girls in this world are yelling every day that it would be better to die if they disfigure their appearance. Even if everyone knows that they just yelled casually, this also reflects how serious Levi's mistake was.
