Ding Zhu didn't expect this third room to be so big.

Because the power distribution map did not indicate the size of the room, she had a preconceived idea that the room in the office was actually the largest, and then she went to the lounge first, and confirmed her idea even more, thinking that this was the layout, so that when she entered the last room, she was completely shocked by the enormity inside.

This room is at least five or six times the size of the power distribution office, and if it is just large, it will not surprise Ding Zhu so much, what really makes her stunned is the circular surveillance curtain wall composed of dozens of monitors in this room.

Although there were a lot of surveillance cameras blown up in the riot just now, it did not affect the overall monitoring, because in these countless camera surveillance, the few black screen cameras are just a few inconspicuous, and more surveillance screens are complete and clear.

Ding Candle stood quietly in front of the surveillance screen, her eyes swept over the small squares, and soon she had a complete understanding of the area monitored by the camera.

Such a huge monitoring screen actually divides the entire monitoring area into five to six pieces.

There is external monitoring, there is ground monitoring, there is a layer of monitoring, there is a second layer of monitoring, a basement monitoring, a second underground monitoring, and a monitoring of several gates in the corner.

There are as many as 300 to 400 surveillance screens in each area, so many pictures can clearly see the movements of everyone in the entire building.

For example, now Ding Candle saw in the surveillance on the second basement floor that the young people who had just rioted were being escorted back to their cells by many hooded men, and their every expression of struggle and every painful action Ding Candle could see it clearly.

Just when Ding Candle was still studying the surveillance, Qin Ge walked in from outside the door, as soon as he entered this room, it was obviously the same reaction as Ding Candle, and he was also shocked by so many cameras and surveillance videos, and was stunned for a few seconds before he was surprised: "This is actually a monitoring room." ”

"That's right." Ding Zhu didn't look back, just quietly looked at the surveillance screen in front of him: "I didn't expect that the monitoring room would be located on the second basement floor of the entire building." ”

"Second basement?" Qin Ge didn't find the overall map of the entire building in the computers of the two engineers, so he wasn't particularly clear about the building.

Ding Candle shared all the information he had observed with him.

Qin Ge touched his chin and thought about it, Ding Zhu was curious: "What's wrong?" What's the problem? ”

"No, no problem, I just think this should be an exam room."

"Exam room?" Ding Zhu twitched the corners of his mouth: "How can it be the examination room?" ”

"Have you forgotten that I told you that all these people are here because of an exam?"

"Of course I haven't forgotten, but it doesn't look like an exam room here, right? Or will the sleeping examination room set up a cell underground? Ding Candle intuitively felt that Qin Ge's speculation was wrong.

"I'm not speculating, I found a power supply map in their computer, the date on it is not a few days different from the time indicated on the computer, it can be seen that it came out a few days ago, and the lighting of several examination rooms is clearly marked on the power supply map." Qin Ge seriously recalled the information he had just seen, and then walked to the monitor to carefully observe all the surveillance videos.

Soon he saw what he was looking for in the area on the second floor above ground, and he pointed to the quiet pictures and said, "Look, these should be the exam rooms." ”

Ding Candle looked at it, it was a lot of empty rooms, some of the rooms were arranged like a kindergarten game room, some were arranged like classrooms for classes, and some were simply large conference rooms, no matter where they looked at it, it didn't look like an examination room in the general sense, but Ding Candle still subconsciously agreed with Qin Ge's statement.

These rooms, which are large in number and can accommodate a large number of people, must be the examination room.

It's about this life-and-death exam.

"What are so many people doing?" Ding Candle's gaze moved down slightly from the empty examination room, and she saw that there were a lot of people gathered outside the ground and on the first floor, but they were all relatively far away lenses, so she couldn't see what it was.

Qin Ge climbed onto the stool of the monitoring computer and began to find the keyboard, his fingers jumped quickly, but the monitor said that he needed a password, Ding Zhu couldn't help but feel a little pity, but Qin Ge didn't pause at all, but continued to search for something on the computer.

"You know the password?"

"I don't know, but it doesn't matter if I know if I don't." Qin Ge stared closely at the large number of digits that were quickly swept across the computer monitor, the silver light on his immature face, which looked so focused and serious, but not quite like a six-year-old child.

Soon, with Qin Ge's cracking, this computer, which seemed to have a very high secrecy factor, raised a white flag.

"Do you have any research on controlling surveillance cameras?" As early as when Qin Ge took over the search for the engineer's computer, Ding Zhu knew that this person was very good in the computer field, and then he easily cracked the computer, and she was more confirmed about this matter, and now even saw that he accurately found a few specific cameras that were adjusting his focal length, and felt that this person knew a little too much.

Qin Ge didn't look back, just stared at the picture on the camera, carefully debugged, and replied casually: "This kind of electronic product is universal, there is nothing strange about it." ”

Well, my lack of proficiency is probably a reason why I don't understand, Ding Zhu comforted himself seriously.

"This, this camera, you find this, pull it in and look at it, you see that there are words on the back of this person." Just when Qin Ge was still beating back and forth on the cameras monitoring the crowd, ready to look for a clue that could be found, Ding Zhu suddenly spoke.

"Which one?" Qin Ge raised his head and glanced at the camera that Ding Candle pointed to, and sure enough, he saw a few words in the current blind spot of this camera, but because of the angle of the camera now, he could only see a few letters.

The camera is followed by another image taken from the opposite angle, again with only a few letters, but there is also something that looks like the edge of the podium.

"What is this?" Ding Zhu stared at the edge of the podium, and could only see a hand waving from time to time.

Qin Ge, who had already cut into the two cameras, immediately began to adjust their positions, and finally, they could see the front picture of the two cameras clearly......
