Let's play horror games

You choose to dig the ground.

You straighten the minecart and clean the surrounding area with your shovel.

The bottom is also a gravel road, but you always feel that it is a little unnatural.You squint your eyes for a moment, and there seem to be two parallel lines that are not very obvious, about three paces apart.

You think of the traces you saw on the road when you first came in.

This is... the rails?

There are eye-shaped stones all over the ground, staring at you like many eyes, making you feel a little uncomfortable.Bending over to clear also makes your waist and left hand ache, but you still try to clear the track.Soon, two curved lines appeared on the ground.

The strange thing is that the car marks do not extend to the door, but to the foot of the wall on the left.

Brother Hei had already walked to that side and began to grope for the wall.You also touched and knocked, and only touched a hand of dark reddish brown sand.

The wall carried a faint fishy smell.The image of building a wall with flesh and blood flashed through your mind, and you quickly waved it away.

Brother Hei stopped and stared at a certain wall.You can't see anything special about that wall at all, and he tapped a few times with the handle of the knife, as if confirming something.Then he raised his knife and stabbed in!

You expected to hear a harsh sound, or see the sword being broken, but the Taidao just disappeared into the wall without a sound.There were veins in his arm, and he pressed the knife down.

You hear a slight snapping sound.

He continued to press the knife down, with an even speed and an unchanged expression, as if he were cutting a piece of soft clay, or a piece of cake.You poked the wall, it was indeed hard.

OK, even if Brother Hei kicks a sea monster with his feet and fights a tiger with his hands, you won't be surprised anymore.

Not long after, Brother Hei used a knife to draw out the square outline of the door, and then touched the wall a few times.I don't know how to do it, but he just pulled down the whole wall even though his fingers didn't have any strength!

You suspect for a while that there are suction cups on his hands, and for a while you suspect that he was raised by a bear.

What did you eat to be so strong?Brother Hei's arms are obviously not thick!

You want to touch his arm, or lift his shirt to see his six-pack, but luckily your mind stops you.

As you might expect, there is a bronze door behind the wall.It should have been golden, but now the rust stained layers of green flowers.

You notice that in the wall that has been pulled down there are many white rubble smaller than a fingernail, with jagged and sharp edges, reminding you of broken shells on the beach.

You curiously took a piece, studied the traces on it, touched it, and always felt that the texture was somewhat familiar.After a few seconds, you suddenly understand and immediately throw the gravel away.

These, it seems... are all broken bones.

Whose bones are these, chicken?pig?monster?Or... people?

When you and Bones looked at each other, Brother Hei somehow touched some mechanism.The door made a toothache creaking sound, as if it would disintegrate in a second, but it opened slowly.

"Yo, it's really slow."

Behind the door is long hair.His head was bleeding, but he didn't care at all. He was sitting in the trolley with a bored face and playing with steel bars, like a big kid playing with toys in a shopping cart in a hypermarket.

The difference is that what he is holding is not a toy duck, but a long steel bar covered with flesh and blood, which sprays randomly when he flicks it.

You couldn't help but took a step back.

Chang Mao: "Wow, one has scratches all over his body, and the other is disheveled and still holding his waist. How fierce were you just now?"

You rolled your eyes.

Chang Mao was touched and said: "Old Hei has no expression every time, very boring. It's still fun for children."

you:……

Brother Hei turned over and got into the trolley as if he hadn't heard of it.

The way to the fourth floor has been opened.But this time is special, it is not a staircase, but a pothole that slopes upwards, and there are rails laid inside.It looks like they are going to go up by car.

"Come on, come on, the old driver is going to drive!" Long Mao shouted.

The trolley is a bit high, and your hands are injured, so you turned over a few times with difficulty, and finally Brother Hei gave you a hand to sit in.

Long Mao poked out his upper body and fiddled with it. Some switch was flipped. With a "click", the trolley began to move slowly.

The three big men are crowded together, and you try to shrink yourself as much as possible, but you still bump into the thighs and shoulders of the people next to you.The tunnel is a bit damp, the ground is covered with thin, white bone fragments, and the cold water drips down the back of your neck from time to time.Your whole body tenses up.

Not long after, you saw the exit of the pothole, where there was a faint red light.

The phone vibrated.You take out your phone, and the APP has a new message.

"Dear player, congratulations on passing the third floor! Current progress: 3/7"

Another 4 floors, maybe you can go home.

You grip your shovel tightly.

*

Your first impression of the fourth floor is that it is hot.It was hot as hell.

The fourth floor is different from the winding third floor, and the corridors and multiple compartments on the first and second floors. It is a larger rectangular room.

There is a huge metal boiler in the center, the ignition point is below, and the conveyor belt that has been shut down is connected to the boiler.There are pipelines around and on the ceiling, which are mainly divided into two colors, iron gray and cement white.The criss-crossing pipelines are like blood vessels intertwining the room, and you even have to bow your head when walking.

Although the equipment appears to be down, you still hear the slight sound of machinery running.

Obviously, here is the factory.You haven't visited the factory, but you always feel that there is an ominous atmosphere here.

Long Mao ran to the boiler, muttering that he was hungry while poking his head, and seemed to want to put the monster's meat in it to cook, while Brother Hei stood by the conveyor belt and pipeline.

At this point, you will:

A check pipeline

B Check the conveyor belt

C check the boiler

D check the ignition
