Shi Sui looked at the situation in front of him and was so shocked that he couldn't make a sound. The people in front of her were all locked in iron cages, their eyes glazed and their expressions numb. She had seen that kind of person, and only people whose spirit and will had completely collapsed could have that kind of look. In the photos taken by the colleague who had gone to follow and report on child abuse in the welfare home, the faces of those children were like this. But the colleague who followed the incident suffered a considerable mental blow because of the news and received psychological counseling for half a year.

- Master, are you alright?

She ordered herself to turn her gaze to the somewhat worried translucent figure beside her, and pulled a forced smile. "I'm fine."

*********

Rewind time to before she found the mystery of the cabinet in Professor Meng's guest room. She remembered that she had two friends who were more able to collect information than Qin Feng, the "head of the IT elite", so she asked them to help investigate the situation here. However, her two friends are not humans, but the main computer in charge of the underground palace built by the ancient super-civilization, this powerful computer artificial intelligence makes special holographic images based on her real friends Tie Yiran and Tie Yirou, and wanders around the underground palace like ghosts. Ever since she had somehow become the master of that palace, the two ghost managers had willingly let her send them. In fact, she didn't take the initiative to ask them for anything, but she didn't expect that the first time it was an unclear situation.

Judging from the information they found, there is a secret passage in the cabinet of the guest room where she lives that leads directly to the study on the first floor. After fumbling around in the cupboard, she found a small groove in the bottom plate, and when she opened it, she saw that there was a hole, and the inside went straight down like a deep well, and it was all pitch black. She took out the pen-shaped flashlight that Qin Feng gave her, picked up the camera and carefully went down the dark passage, and sure enough, she arrived at Professor Meng's study. There was still a faint light in the study, but strangely enough, Professor Meng was not in the study.

It seems that Professor Meng, who lives in the study at night, is likely to be the one who attacked her. But why? She and Professor Meng have no grievances in the long past and no enmity in the near future - is it possible, could it be that Professor Meng is the prisoner of Ye Zhen's incident eight years ago?! She suddenly felt a chill crawling all over her body, the professor was very kind to her in college, and he just wanted to find an opportunity to kill her at any time?!

In the email, it was also marked that there was a tunnel leading to the underground in Professor Meng's study, but the drawings did not draw any secret room or cellar at the end of the tunnel, it was just a dead end. Does this mean that the missing people are not hidden in the tunnels by the Professor? But why did the professor build such a useless tunnel? What's in the tunnel?

She looked at her watch, it was already 12 o'clock in the middle of the night, but the professor was not in the study at all, which was a bit strange, so late, and I didn't hear him go out, where did the professor go?

There seems to be movement under the floor! She was startled, and hurriedly retreated to the dark passage, secretly watching the situation in the study through the gap. After a while, the ground under the desk was pushed upwards, and Professor Meng came out of the ground. I saw that he quickly closed the hole, tidied up the wrinkles in his clothes, and left the study, listening to the sound of footsteps, he went to the kitchen.

She hurriedly slipped out of the dark passage, opened the entrance to the tunnel that Professor Meng came out just now, and sneaked into the tunnel.

The drawings show that the tunnel is fifty meters long, two meters high and one meter wide, with no forks. She turned on her flashlight and took a cursory look at the authentic surroundings. This kind of strong light can illuminate more than 100 meters, and the entire tunnel can be seen at a glance. The height and width of the tunnel are oppressive, as if the walls are squeezing against you, which is very uncomfortable. The walls are simply plastered with cement, and so is the floor, with only a cyan brick wall at the end. The ground is flat and you don't need lighting to walk. In order to save power, she turned off the flashlight and walked straight to the end.

Holding on to the wall, she soon came to the end, and found that the brick wall of the wall at the end was obviously different from the ordinary brick wall, and she turned on the flashlight again—she couldn't see it from a distance just now, but now she saw that this wall seemed to be a little familiar.

"This symbol ......" She carved a symbol on the brick beneath the wall that she had seen - it was the one that had been carved into the brick of the mechanism when she and Xiao Mo opened the door to the central area of the underground palace! Could it be that there is something behind this wall that has something to do with the underground palace? Who is Professor Meng?

Her mind began to think in a daze, and suddenly she hesitated. Shaking her head, she decided to take a look at the wall first.

Pressing that symbol, the wall slowly rotates backwards, and an entrance appears. She stepped sideways and cautiously inside, and the entrance behind her slowly closed.

The passage behind the wall resembles an Icelandic glacial cave with a turquoise glow, except that the light does not shine through the sunlight of the ice, but through the wall itself. The neat brick walls on both sides are so tight that there are no gaps, and it is as if one is walking into a corridor that is thoroughly illuminated by the light of fireflies.

But this scene was no stranger to her, because it was exactly the same as the magical underground palace that drifted in the underground magma!

There's no need to turn on a flashlight here. She let out a light breath, turned off her flashlight and walked down the passage. If it's the same structure as the underground palace, then there should be small rooms here as well. Could Professor Meng just lock Ye Zhen and them in a room here? If the professor is really the prisoner who kidnapped the villagers and Ye Zhen eight years ago, what is his purpose? Is it the research topic about youkai that he himself insists on?

She shook her head to herself, everything is still uncertain, and speculation is only to add to her troubles, let's go find Ye Zhen and them first. If this was really part of the underground palace drifting through the underground, she really had the right helper to ask the caretaker brother and sister for help.

She took out the "Fuxi Thing" stuffed into the inner layer of the camera bag, and according to the two AIs, as long as she used this, not only could she contact them directly, but it would not be a problem to control all the underground ruins generated by the underground palace. But the most troublesome thing about this thing is to rely on the "will" to control, how to think, it will do what it does, if it is a duplicitous guy who wants to operate this, it is estimated that it is enough. And it's not so easy to operate without distractions. "Then give it a try." She took a breath.

- Master, are you looking for us?

Two translucent figures suddenly appeared beside her, and the two faces of a man and a woman who were extremely similar looked at her with similar and different expressions. "It also came up too quickly." She stuck out her tongue. Thankfully, it went well.

- Because this is part of the underground palace, and we have our backup data, it is very easy to appear. It's just how did you end up here?

The question of "Yiran" made her smile bitterly, "It's just a mistake." Didn't I read the remodeling drawings you found for me? I didn't expect the tunnel to be connected here. ”

- Master, now that this place is under your control, what do you want to do?

"I'm in control now?" She was a little surprised by the expression of "Yirou", "Someone controlled this place before?" ”

- Yes, it's a man named Meng Fan, who controlled it before you used this device. Judging from the records of his actions left in the system, he is by no means the good man who his master thought he was.

She just listened, without a shocked or excited reaction, maybe she was mentally prepared? "In that case, can you check if anyone else is here?"

――Absolutely. Forty-eight meters away from here, there were three people.

"Three people? Are you not mistaken? She asked "Yirou" to confirm, is it not only Li Zheng and Ye Zhen here, is it really as she thought, those missing people are all locked up here?

- No, and one of the three men is a man and a woman, like Meng Fan, who has two sets of genes.
