The two investigators took out their mobile phones and tried again, but the results showed no signal.

All had no cell phone signal.

By now, it has been confirmed that it is a black scourge.

At this moment, everyone heard heavy footsteps coming from the stairs on the first floor, and went out to check, only to find that the long staircase was empty.

"Who is it?" Shen Xiu blurted out.

"Coach Shen?" came the voice of the driver Xiao Wang.

"Brother Wang, is that you, where are you?" Shen Xiu asked.

Suddenly there was silence on the stairs again, and there was no more sound.

Shen Xiu chased downstairs, but still didn't find any figures, only the bottomless abyss and thick fog in front of him.

At the same time, Xiao Wang's perspective.

The driver of Xiao Wang, who stayed downstairs, sensed that something was wrong and climbed up to the second floor, only to find that room 201 was empty, and there was no one, but he vaguely heard Shen Xiu's voice coming from the door of room 201.

Obviously there is no one, where did this voice come from?

Xiao Wang asked other neighbors again, and they all said that they didn't see anyone, and a group of big living people in room 201 suddenly disappeared out of thin air.

Xiao Wang suddenly thought of something, and was so frightened that he crawled out of the residential building, took out his mobile phone, and called Kunlun's report number tremblingly.

"It's a secret room, we're trapped here. The bald investigator said.

"Is it really a secret room type, I can still hear the driver's voice just now. Lin Xiaolei said.

"When the black scourge was first born, the contact with the outside world was not completely sealed, and now the time window has passed. The bald investigator said.

"Oh, then what should we do?" Lin Xiaolei said urgently.

"Haven't you studied it in school? There are only two ways to escape from the secret room-type black scourge, one is to kill the demon who created the evil scourge, and the other is to achieve the conditions for restraining the demon. Another fat investigator said.

Method 1 is easy to understand, the demon is the creator of the black scourge, as long as the demon is killed, the black scourge will naturally disappear.

But for ordinary people, option one is almost an impossible task.

And the second way, just like there must be darkness and light, and there must be evil and justice, when a demon appears, there must be something to restrain the demon, and if you find something to restrain it, you can survive.

"It's not scientific. ”

Li Congjia looked at the billowing fog outside the window, and still didn't want to believe that he was suddenly dragged to this dangerous place like a horror movie.

"Gödel's theorem has long been explained, every system of scientific theories has some areas that can never be proven, and the science you are talking about is not very scientific. The bald investigator said.

"What theorem?" Li Congjia didn't understand.

"Before I changed careers to become an investigator, I was a math teacher at No. 1 Middle School, and you are also a student at No. 1 Middle School, so you can call me Mr. Lei. The bald investigator said.

"You're a Thunder Tiger? Oh, I'm sorry. Lin Xiaolei has also heard of Mr. Lei's name, it is said that his questions are particularly difficult, and every exam will hit students' self-confidence, and it is an indiscriminate blow between a scholar and a scumbag, so he has the nickname Lei Laohu.

However, Lei Laohu resigned a few years ago, and he had no chance to "scourge" Lin Xiaolei's term.

"It's okay, I increased the difficulty of the exercises, also for the good of the students, but unfortunately there are only a few people who understand. Teacher Lei smiled.

It turned out that the investigator was a teacher from his alma mater, so everyone was a little closer and less nervous.

"Teacher Lei, are you a chivalrous man?" Li Congjia said.

"Xiao Zhou and I are not chivalrous, we are just investigators of Kunlun. Teacher Lei said.

Although it was expected, Li Congjia was still a little disappointed.

The investigator is only Kunlun's outsourced work, responsible for the preliminary investigation of the suspected black disaster, and after confirming that it is a black disaster, there will be Kunlun's knights to deal with it.

Without the help of the knights, it would have been much more difficult to escape from this scourge.

"Don't worry, although we are not chivalrous, we are also professional in dealing with black disasters, and now we can only hope to live if we unite and face it bravely. Teacher Lei said.

"Teacher Lei, you tell me how to do it, we all listen to you. Chen Luoying said.

"Teacher Lei, we are under your command. Li Congjia said.

"Well, don't go out now, first gather the things in the house that can be used as weapons, the boys take the weapons, and the girls take the armor. Teacher Lei said.

Next, everyone collected some weapons, Chen Luoying and Gu Mingxi each took a pot as a shield, Lin Xiaolei took a bench, Li Congjia took a kitchen knife, and Cui Yan took a sledgehammer.

Shen Xiu took a clothes pole, although it was a little thinner, it was metal, and the front was sharp, and it could cause some damage if you stabbed it hard.

Seeing that everyone was ready, Mr. Lei was the first to walk out of the door of Room 201 with a metal candlestick, followed by the others, and Zhou Fatzi was the last.

Two investigators, one in front of the other, escorted several students in the middle.

When he came to the corridor outside, Shen Xiu found that the corridor environment had undergone new changes.

The walls, with many small advertisements on both sides, have become rotten and mottled, many of the cement have fallen off, and the small advertisements have become shredded paper, as if they have aged for decades in an instant.

Because of the fog, there is very little light shining on the stairs through the corridor windows, and the corridor is quite dark.

The candlestick in Mr. Lei's hand is lit with candles, which can not only illuminate it, but also poke it with sharp metal horns when encountering enemies.

The dim candlelight flickered, causing the shadows of the crowd to distort on the walls like ghosts.

"Brother Rei......"

The fat man at the end of the team called softly, and his voice trembled slightly.

Everyone stopped suddenly, Shen Xiu's attention was originally in front, turned his head to look at Zhou Fatzi, and immediately took a breath of cool air.

I saw that on the steps under Zhou Fatzi's feet, something was wriggling, looking like some kind of living thing.

Because of the dim light, I can't see clearly.

It is precisely because of the lack of clarity that it gives everyone the imagination to use their fears, and they all stay away from Zhou Fatzi.

Teacher Lei stepped on the steps, walked back quickly and lightly, and stopped two steps in front of Fat Zhou.

With the lighting of the candlestick in Mr. Lei's hand, everyone can see clearly what is under Zhou Fatzi's feet.

It was a bunch of black cockroaches, densely packed together, and there were hundreds of them, to say the least.

They closely surrounded Fat Zhou, so Fat Zhou didn't dare to move.

There were a few cockroaches dangling their thin tentacles, and their six legs were swinging, and they had already climbed up to Zhou Fatzi's calves.

If it was an ordinary cockroach, Fat Zhou would not be too scared to move, but these cockroaches were not ordinary at first glance.

Teacher Lei was still observing the cockroaches at Fat Zhou's feet, when he heard Li Congjia whispering, "Teacher, there are also on the wall." ”

Mr. Lei looked at the wall next to him, only to see a surge on the wall, like ripples in black water, first the outline of many cockroaches came out of the wall skin, and then a large group of cockroaches emerged out of thin air, densely glued to the wall, the scene was only disgusting.
