Outside the electric fan factory, it was late at night, the streets were deserted, and there was no one except for the dim street lamps.

Shi Yan stood in front of the iron gate outside the red brick building, rubbed his nose, and decided to explore the red brick building in depth tonight.

Pushed open the iron door and walked in, the entrance of the stairs was still the dim street lamp.

Up the stairs, it was pitch black, and there were no more dim street lamps that night, and there were no neat corridors.

All the way up to the rooftop, nothing happened, except for some sundries on the rooftop, there was nothing else.

Shi Yan looked around suspiciously, where did the strange shadow with long hair and face go? Where's the room with the clean comb?

Shi Yan went up and down several times, but he couldn't get the point.

Finally came to the first floor, there seemed to be a door next to the stairs, Shi Yan remembered that the murders happened in room 101, and when he came to the door, he saw that the room number was 101, and there was a yellow seal on the door.

It is the room where multiple murders have taken place.

Shi Yan pushed the door and went in to see that there were two bedrooms and one living room in the house, and there were several pieces of dusty furniture in the hall.

Walking into the larger room, it was the room where the clean comb had been kept that day, but now the comb was gone.

It should be here, Shi Yan searched carefully, the cabinet, the big bed, and the bedside table were all very simple, and they were checked after a while, and nothing was found.

Shi Yan didn't even find anything when he checked the walls.

A red mist erupted from Shi Yan's eyebrows, slowly filling the entire room.

Shi Yan closed his eyes, as if he was feeling something.

Suddenly, he opened his eyes, stared at the large bed, and slowly walked to the bed, and flipped it up, revealing the floor under the bed.

Shi Yan squatted down, stared at the floor for more than ten seconds, stretched out his palm and pressed it on the floor violently.

There was a loud bang, and the floor caved in, revealing a deep black hole.

Shi Yan's golden blood qi was running, his eyes emitted a faint golden light, and the scenery in the darkness was unobstructed.

Looking at the black hole, it seems to be six or seven meters deep, and the flat ground can be seen below.

Shi Yan hesitated, six or seven meters high could not trap him, so he decided to probe down.

The red mist wrapped around his body, Shi Yan jumped into the cave, and soon fell to the ground, looking around, this turned out to be a strong cave more than two meters wide and six or seven meters high.

Looking at the four walls of the cave, it does not look like it is artificial, but it looks like it is naturally formed.

At the bottom of the cave, there is also a diagonal downward passage, the surface of this passage is convex and undulating, but it is natural, not artificial.

Shi Yan probed down the passage, all the way down, extending downward in a spiral, and walked a long way.

"Ding, I noticed that the concentration of gray fog has increased." Suddenly, a message came out of the system.

Shi Yan paused, and the energy similar to the gray mist appeared in this red brick building, maybe this passage was the reason.

No longer hesitating, Shi Yan continued to move forward.

didn't go far, the red mist suddenly rolled up, and it seemed to be very excited, Shi Yan just wanted to ask.

"Ding, there is a gourmet feast in front, hurry up."

A piece of information in the system made Shi Yan stunned.

Or a gourmet meal? I really think I'm a foodie.

Although he thought so, his feet accelerated, and he didn't go far, and suddenly an open area appeared in front of him.

There seemed to be a transparent membrane in front of the open area, and the membrane seemed to have cracks, and a trace of gray mist was slowly seeping in.

In front of the crack, a dark shadow was bathed in gray mist.

The black shadow suddenly turned around, it was the strange figure with long hair covering the face, and there were still shallow mottled scars on one arm.

Seeing the black shadow, the red mist rolled excitedly, and with a wave of Shi Yan's hand, the red mist began to spread, slowly filling the stone cave.

The black shadow let out a sharp and piercing scream, and bursts of black smoke spread out of its body, as if it was afraid of the red mist, but it was unwilling to scream.

The red mist forced the black shadow closer and closer, and the black shadow's cry became more and more sharp, and the black smoke billowed out, like madness.

Finally, the red mist collided with the black smoke, making a roaring sound, as if it were substance.

The black smoke makes a sizzling sound, and it is constantly melting and decreasing.

The black shadow finally couldn't bear it anymore, and rushed towards Shi Yan like crazy, a picture of dying together.

Shi Yan had already been keeping an eye on it, and when he saw this, he activated the skill "Ghost Flash", and his speed increased greatly, and he quickly flashed to avoid the black shadow.

The black shadow's whole body was sizzling at this time, as if it was being corroded and swallowed by the red mist, and its body continued to dissolve.

The black shadow didn't dare to fight, and rushed into the passage where Shi Yan came down and wanted to escape, but the figure had already staggered, and it seemed that the injury was not light.

How could Shi Yan let him escape? A flicker caught up with the black shadow and slammed a punch into the black shadow's back, wrapping the fist in a cloud of red mist.

The fist slammed into the black shadow's back, and the red mist was even more smashed into the black shadow's body, and a terrible scream resounded through the underground passage.

The black shadow could no longer escape, and the red mist rushed left and right in its body, wreaking havoc, and the rolling red mist outside surrounded it again, completely submerging the black shadow.

The red mist rolled, and the screams became louder and lower, until finally there was no sound at all.

After a few more moments, the red mist cleared, and the black shadow was gone, except for a black comb lying on the ground.

Shi Yan picked up the wooden comb in the past, but it was so cold that he almost couldn't hold it steadily.

The hand that touched the wooden comb had become jet black, Shi Yan was startled, and hurriedly threw the comb on the ground.

What is this wooden comb? How awesome is it?

However, Shi Yan had experience in this, and the red mist came over and wrapped the jet-black palm, and soon the jet-black disappeared completely.

"Ding, the digestive system has obtained the "Eye of the Dead" skill, is it strengthened?" Suddenly, a system message appeared in my mind.

Hey? Shi Yan was surprised, that strange shadow just now actually had skills?

"Intensify." An accident is an accident, but who is afraid of having more skills?

The red mist enveloped Shi Yan, and after a while, the strengthening was completed.

Shi Yan activated the Eye of the Undead, looked around, and suddenly found that the gray mist in front of him was no longer gray, as if it was transparent.

Shi Yan was happy in his heart, he had always had a headache with the existence of the gray mist, which made it difficult for him to move like a blind man, and now it was solved by "The Eye of the Dead".

It will be easy to get in and out of the gray fog in the future, Shi Yan smiled, this harvest is worth it tonight.

Shi Yan stepped forward again to observe the membrane and the crack, which should be a meeting point between the two worlds, but the separating membrane had cracked, leaking some gray mist, allowing the strange shadow to absorb and grow.

If you guess correctly, the strange shadow should be a ghost in the family of the Republic of China, who was nourished by the gray mist and grew into a powerful ghost by chance, so there was a series of murders later.

Shi Yan stretched out his hand and pushed the membrane, but he didn't move, it seemed to be very strong.

After studying it repeatedly for a long time, I couldn't break through the membrane, so I had to give up for the time being.

He turned his head and looked at the wooden comb on the ground again, and asked, "Do you have a way to put it away?" ”

"Absolutely."

The red mist rolled and quickly wrapped the wooden comb, and by the time the red mist dispersed, the wooden comb was gone.
