The missing police officer was in his forties and looked very upright. He came to investigate in plain clothes.

At that moment, several crews were filming at the film and television base. He observed and patrolled inside as if nothing had happened, and then chatted with one of the crew members for a while.

Then he walked out of the base.

"Didn't he disappear in there?"

Yan Mofei felt a little confused and continued watching. The police officer then walked around the film and television base and behaved normally. However, as a police officer, since he was investigating, he would definitely look around and occasionally ask questions to people nearby.

He didn't get any useful information, so he bought a pack of cigarettes and squatted in a corner to smoke.

There is no surveillance here, so it looks like a blind spot.

Yan Mofei didn't know why he was squatting here, maybe just to find a place to smoke.

At this time, a staff member from the crew came over and continued to talk to him. There was nothing wrong with the content, but when leaving, the other party looked at him deeply.

The police continued to investigate but did not find any useful information, so he prepared to go back.

But just when he had walked a dozen steps, he suddenly froze. Then, as if controlled by something, he turned around again with an expressionless face and returned to the corner where he had been smoking before.

He pressed a brick on the wall in the corner, and the ground there suddenly collapsed, forming a hole.

The police descended slowly into the hole and then disappeared.

"What's going on? My ability is ineffective? I can't even see the scene inside."

Yan Mofei felt very strange.

The inside of the cave was pitch black, as if it absorbed all the light sources, making it impossible to see through.

The policeman disappeared inside without a trace.

"What went wrong?"

Yan Mofei went back to check and found that when the crew member was talking to the police, he patted the police.

Yan Mofei slowed down and looked carefully, only then did he realize that the man had something in his hand, something like a short needle, thinner than a hair. It was so thin that if Yan Mofei didn't have this ability, he wouldn't be able to see it at all.

Yan Mofei checked the place where the police officer was photographed again. It was too detailed and the photo was taken directly on his clothes, so he really couldn't see anything.

I guess even if someone checked it, it would not be visible to the naked eye.

Yan Mofei immediately took a photo of the staff member and a clear photo of the slender object in his hand and sent it to Shen Gu'an.

"Investigate this person's identity and what he has in his hand. Check the bodies of the previously deceased police officers to see if this thing exists."

Chen Gu'an didn't expect a new clue to appear so soon. He gave instructions without stopping, and then sent a message to Yan Mofei: "This thing is almost invisible to the naked eye. How did you find it?"

Yan Mofei said, "Don't worry about these things. I'm just providing clues. As for how I found out, I can't reveal it."

Just like the information he leaked, no one has ever found out how he leaked it.

Yan Mofei was very interested in the black hole-like thing. He went out and came to the corner.

This place is indeed very hidden. The corners on both sides can block everyone's sight. Moreover, the road is narrow and there are a lot of debris on the ground. Most people will not come here even if they see there is a road here.

All this further proved that the staff member's arrival was not accidental. He came here on purpose because he knew that the police officer was here.

"System, is there any surveillance in this area?"

The system was obedient. Yan Mofei lowered his voice, and its voice was also deliberately lowered, sounding as if it was whispering to Yan Mofei: "Host, I have checked, and there is no surveillance here. It's just that there are anti-detection materials underground, as well as electromagnetic interference systems. Even with the capabilities of this system, it cannot pass the detection."

It can even isolate his system, no wonder it can also isolate the abilities given to him by the system.

Yan Mofei looked around and after making sure that no one around had noticed his trace, he came to the place where the police officer had stood before and stepped on it.

There was soft soil underneath, and the grass on it was quite lush. The edges were tightly closed, so no one could tell that it could rise and fall.

Just in case, Yan Mofei stood at the edge and then reached out to press the wall where the police officer had pressed before.

"No response? Is this some kind of gravity compression system?"

He stood on the platform again, pressed the brick again, and waited for a long time, but there was still no response.

"This is fucking science! This is the first time I've hit a wall."

Yan Mofei continued to think about what the problem was. Either the lift was broken, someone had shut it down, and so no matter how hard he pressed it, it wouldn't start.

Otherwise, there is another condition, that is, only those who have been hit by that thing can go down.

He couldn't just ask someone to give him a shot just for the sake of investigation. That would be too stupid.

"Forget it, let's keep watching."

Yan Mofei returned to the hotel again. He wanted to investigate the disappearance of other police officers.

After this investigation, Yan Mofei became uneasy because the places where these three people disappeared were different.

Although all of them disappeared in the film and television base, the other two were inside the base. One disappeared in a corner of a lobby, and the other pressed the same lift in a very inconspicuous place on the wall.

Another one disappeared in the bathroom, in the most unexpected place, right in front of the sink. And the place he pressed was under the mirror.

Both the place where the pressure was applied and the ground were restored perfectly afterwards, without any gaps or traces.

The three people came into contact with different people. One was a crew member, one was a worker at the film and television base, and the other was a bathroom cleaner.

The common point is that they were all hit by the needle, then became numb and obedient, and then automatically pressed the button and sank into the ground.

Why were these people here, and why were they targeting these three police officers? Was it because they had discovered their identities?

Yan Mofei checked the actions of these three people in the past ten days and found that they were indeed staring at people entering the film and television base. Then they discovered the differences between the three people and took action.

Normally, you can't tell that these three people are just ordinary staff members here.

"Are they guarding something underground?"

Yan Mofei used his ability again to check the relationship network of the three people, and the results showed that the three were colleagues.

One of them serves the crew, the other two serve the base, and since they are colleagues, they can only be in the same group.

"It's really interesting. I guess I really need to go down and see it myself."
