After opening the sealed door on the first floor for ventilation, Ding Chen went back to the third floor for a nap, and when he woke up again, he found that Uncle Potato had woken up and was drinking broth with a stainless steel cup. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 infoKiki fell asleep wrapped in the blanket that Uncle Potato had just slept with on the haystack next to the fire. There was always a fire in the hallway, and the walls on both sides were very hot after reflecting back the heat, so Kiki looked like she was sweating again, and there was a lot less dirt on her face than before.

Ding Chen stretched out carefully, slowly got up, and Uncle Potato stretched out the cup in his hand and compared it to him. Meaning to ask him if he wanted to drink broth, Ding Chen shook his head, gestured to Qiqi, and then stretched out his finger to his lips, signaling Uncle Potato not to wake her up.

Uncle Potato smiled, lowered his head and continued to drink his broth.

Ding Chen cautiously moved to Uncle Potato's side and whispered, "You go and sleep for a while, I'll keep vigil." ”

Uncle Potato glanced at him, put down the cup in his hand and said, "Listen to Kiki, you went to the first floor just now?" ”

"Yes." Ding Chen briefly described the scene he saw.

Daddy asked, "What's on the first floor?" ”

"A door." Ding Chen replied.

There is only one staircase in the corridor of this building, the staircase on the third floor is on the left side of the corridor, the staircase on the second floor is on the right, and the staircase on the first floor is also on the left. The sealed door on the second floor is installed between the staircase and the corridor, and the staircase must be passed through the sealed door to enter the corridor.

When the sealed door on the first floor opens, you can see another door standing on the opposite side of the hallway. However, after the sealed door on the first floor was opened, because of poor ventilation, the oxygen content inside was too low, and Ding Chen's torch was directly extinguished, and Ding Chen did not dare to go in to check, but came back to sleep.

When he proposed to keep vigil by himself again, Uncle Potato shook his head and said, "I've slept enough, I don't sleep that much when I'm old, so you can go back to sleep." ”

Ding Chen hesitated for a moment, a senior scavenger like Uncle Potato would not give a promise indiscriminately, he said that he could come to the vigil, then he must feel that he has the ability. So he said to Uncle Potato, "Then I'll go to the first floor and have a look." ”

Uncle Potato understood what Ding Chen meant, the corridor of this building was closed, and it could only be ventilated through the passage on the roof of the third floor, and as the floor went down more and more, the speed of ventilation naturally became slower and slower. If there is still space behind the door on the first floor, it is obvious that it will take a certain amount of time to ventilate after opening it, so it is necessary for Ding Chen to open it as soon as possible.

The scavenger who appeared yesterday had already warned them that there were still people in the neighborhood who were watching this place, ready to come and pick up the bargains. The three of them are not afraid, but it is best not to stay here for too long. After all, people's energy is always limited, and once something goes wrong, the loss is too great.

Ding Chen made another torch, carried it back to the first floor, and walked into the corridor on the first floor through the sealed door that had been opened. Only then did I find that the corridor on the first floor was different from the corridor on the second floor and the third floor, and the offices on both sides turned out to be really doors. He raised his hand and knocked on it, and found that the doors were also made of steel.

Obviously, these doors exist to add authenticity to the office, but in order to maintain the strength of the walls on both sides, these doors are not regular wooden or steel security doors, but are designed to resemble sealed doors in hallways.

Such doors are obviously not cheap, so there is no need to camouflage the second and third floors, and in order to save costs, the doors are simply omitted.

Because they weren't really office doors in the first place, none of them had a doorknob on them, instead they had a round handwheel on the door, which looked a lot like the one that could be rotated on the watertight door of the cabin.

Ding Chen took a breath, held a handwheel in front of him, and rotated it counterclockwise. There was a screeching grinding sound inside the sealed door, and the handwheel was unscrewed.

After the handwheel turned to the end, Ding Chen stopped for a moment, pulled hard, the door was opened, and a breath of fresh air rushed to his face. What appeared in front of Ding Chen was a messy office, and the riot-proof glass on the opposite window had been broken into a large hole, and it was from there that the wind blew in.

Ding Chen looked at all this in front of him and laughed silently.

He closed the open door again, and walked towards the one at the end of the hallway. The short ventilation just now made the air quality in the corridor much better, which made Ding Chen feel comfortable.

The corridor is not long, and the two sides are separated by sealed doors, so the length that Ding Chen actually walked is only half of the total length of the corridor. He stopped in front of the door and reached out and touched it.

The sealing environment of this building is very good, the corridor is dry and clean, and there is no dust, so Ding Chen can clearly judge that this is another heavy steel sealed door, and it seems that the amount of steel used in this building is considerable. Ding Chen thought to himself that if a large number of such buildings were built across the country, perhaps there would not be a large-scale bankruptcy of the steel industry, and sure enough, it would still depend on the government to boost domestic demand.

The surface of this door is very flat, and there is no knob. Ding Chen tried to push it with his hand, but he didn't feel like he could push it. If the thickness of this door is the same as other doors, I am afraid that only a large cutting machine can be used, and the hand-held cutting machine carried by Ding Chen is estimated to not even be able to cut through the door.

He took a step back, pulled out the battery lamp and took a closer look, finally focusing on a small box with a waterproof lid on the wall next to the door.

There is no doubt that this is an electronic door, and the key to open the door is here.

To be honest, after Ding Chen confirmed this fact, he was ready to give up in his heart. This electronic door must use electricity to open the door, and without electricity, even if he can modify the key module, it is impossible to generate the power to open the door. Unless he can find a powerful enough external power source for the building.

Powering such a door is not an easy task, and it is never as simple as lighting energy-saving lamps for the wires in an apartment. Often, such doors are combined with complex security mechanisms. There may even be a central control center for identification. If the amount of data is large enough, then the control center is likely to be a large computer cluster directly, requiring enough power to take down the power carts that several apartments are currently using.

So if we really want to restore the power to this building and make the original equipment running, Ding Chen may need to restore the wind power plant on the top of the mountain.

To be honest, it was difficult for Ding Chen to determine which one was more difficult to restore the power generation capacity of the wind farm and slowly cut the door with a hand-held cutter.

However, since he has come to the door, it is not Ding Chen's style to pack up his things and return directly. Even if he did get to the south wall, he would have to hit it to be sure.

So with a glimmer of hope, Ding Chen reached out and lifted the waterproof cover on the input device, revealing a facial recognizer with a twelve-key keyboard with a small screen.

At this time, something unexpected happened to Ding Chen, as the waterproof cover was lifted, the small screen actually lit up.

Obviously, there is no complete loss of power supply here as Ding Chen imagined.
