A breeze swept in with the opening of the secret passage.

The taste is moist and slightly salty. Ye Yuyue walked in without hesitation, and as he entered, the door of the refrigerator closed.

The stairs were upward, uneven, and the tunnels weren't high, and he had to walk half-haired.

Fortunately, this time the lighting was not a problem, and every few meters there was a small oil lamp that emitted a yellow light.

The tunnel looks rudimentary, with small stone bricks lining the sides, and the steps are simply stacked with stone bricks.

As he walked, the smell of humidity in the air grew heavier.

After walking for about ten minutes, there were some droplets of water oozing from the stone bricks under my feet. The staircase began to slip a little, and he seemed to hear the sound of water coming faintly from behind him.

How far is this processing plant? He tried to speed up his pace, but there was still no end in sight to the stairs up.

About ten minutes passed, and he couldn't help himself, and he tried to shout, "Anyone?" ”

His voice echoed up and down the staircase, but there was no reply.

I remember that Liu Lanlan once said that the laboratory is located 1882 meters underground, and with the distance he has traveled at the moment, if he does not consider the inclination of the stairs, he even thinks that he is back on the ground.

Could it be that the processing plant is on the ground?

He was a little tired, and the long bending up and climbing the stairs made him feel sore.

He turned around and prepared to sit down and rest for a while, but as soon as he turned around, Rao couldn't help but curse with his cultivation.

"I'm #¥@."

The staircase he had just walked was visibly submerged by the water seeping out of the walls, and the speed of the submersion became faster and faster, even like a churning wave, coming at him from the bottom up.

"Who said that, the water flows down...!"

There was no time to marvel at the magnificence of the view, and he hurriedly continued to crawl upward. That's right, it's crawling.

Because of the urgency of the situation, the speed at which Mao Waist climbed the stairs was far less than his speed at the moment.

The water was flowing faster and faster, and even he felt that his shoes were already wet.

"Damn, shit." He cursed and jumped upwards with all his might, feeling that his physical strength was a little too much to support.

Finally, he climbed to the end of the stairs, and the whole person was slumped on the ground, and the water did not continue to spread upward.

He looked back and saw that the staircase had been submerged in the current.

"Is it an underground river?" Imagining the salty smell in the air, Ye Yuyue got up from the ground, but there was a feeling in her heart that she would have the rest of her life.

If you stay in the hut for a little longer and go up the stairs a little slower, you may have drowned.

He looked ahead.

It was still not a processing plant, the ground was beginning to flatten, and as he walked forward, the smell of dampness fading away.

The number of small oil lamps became less and less, and eventually there were no oil lamps at all.

The pavement changed from a stone brick floor to a dirt road, and he felt more like he was in a man-made cave.

There is darkness in front of me, and I can't see my fingers, and in such an environment, if there are people with dark phobia, it is estimated that they will not be able to support it.

In extreme darkness, the human eye has night vision. It's just that humans are weaker than animals.

Thinking of the words that the nurses in the hospital had taught, Ye Yuyue closed her eyes. When I opened it again after half a ring, the surrounding area was still dark, but fortunately, the surrounding scenery began to come into view, but the visibility was still limited.

The cave was widened and taller, and he could walk on his back.

The long bending made his back tingle, but his pace didn't stop. He was already aware of what had happened in the previous staircase, and even though the head of the lab hadn't mentioned whether there was a time limit for the experiment, if he stopped, something terrible would happen.

After walking for a while, a faint pungent smell entered his nostrils, making him can't help but feel a little sick to his stomach.

What kind of flavor is it? Something like something rotting mixed with the smell of blood. And as he walked, the taste became more and more intense.

Factory, it should be almost there.

He quickened his pace as he thought, and the unimpeded flow of the road made him let his guard down and even trot.

Before he could take two steps, he didn't know what was mixed under his feet, and he stumbled and almost fell to the ground.

He crouched down slightly, and when he saw what was in front of him, his pupils couldn't help but shrink suddenly.

It should be the internal organs of the animal.

The rotting entrails smelled foul, and the yellowing mold covered the entire skin of the entrails.

It was this smell, Ye Yuyue finally didn't know where the pungent smell came from, he couldn't bear it and didn't spit it out, hurriedly stood up and walked forward.

This time he was much more careful. The further you go in, the more "surprises" you have at your feet.

At first, it was internal organs, and then he began to see the limb remains of many animals.

The stench grew heavier and heavier, and his eyes welled up with tears, and if it were for the other participants, he might have been too scared to move any further.

Although the taste was pungent, Ye Yuyue's pace was still steady. From frowning at the beginning, his face changed back to expressionless at the end.

Yes, it only took a moment for him to get used to the taste.

"Only the brave can defeat purgatory."

Is it possible to walk through this wreckage-strewn road, and the experiment is complete?

Then he shook his head again, it shouldn't be that simple.

The first fork in the road appeared in front of me.

There are two forks in the road. One is straight forward. One is to turn left. The intersection straight forward is very narrow, and even a thin figure like Ye Yuyue has to climb to pass.

And at the end of the road on the left, Ye Yuyue actually saw a little bit of light.

Ye Yuyue unconsciously walked towards the position where there was a light source, and with his steps, the light became bigger and bigger. Until he reached the end, there was a dull "bang." Bang. The sound rang in my ears.

What is this sound? Could it be the man in the diary?

A sense of crisis flashed from Ye Yuyue's heart. He stopped where he was, looking cautiously into the hole.

Here, it should be the factory!

What catches your eye is a lot of large machines that you have never seen before. This is supposed to be a cave dug by hand. The cave is very large, with the size of thousands of square meters. These machines have conveyor belts on which animal carcasses are hung. There are pigs, there are horses, there are deer.

These animals look like they've been dead for a long time, and their bodies are covered in disgusting corpse spots!

One end of the conveyor belt is connected to the top of the cave, from where the carcasses of the animals are slowly transported in a downward oblique arc. Ye Yuyue visually measured a height of at least 20 meters, and he couldn't climb it at all.

As the machine slowly moved, the carcass of the animal was slowly pushed into a huge meat grinder at the front. And the stench came from that meat grinder!

This is a meat grinder with an opening pointing downwards. The minced meat is transported directly to another location through the lower exit of the machine.

Ye Yuyue covered her nose with one hand and walked towards the factory.

As he walked, the sound of "bang-bang" seemed to get louder and louder!

The deeper he went into the factory, the stronger the sense of crisis in his heart became.

The layout of the whole factory presents a field shape, and the conveyor belt and meat grinder just seen at the hole are only a part, so there are four sets of similar equipment, distributed around the factory!

When I got closer, I found that these machines were very tall, and there was a 3-meter pedestal by sight, and Ye Yuyue couldn't even see the sides when he walked through them.

Not far in front of him, in the middle of the factory, was a huge wooden house. However, it seems a little out of place with the surrounding layout.

"Bang"

"Bang"

"Bang"

It's regular, but it sounds like it makes the heart tremble.

And this voice came from the wooden house!

The house has a large door frame and several window frames, and there is no glass or doors.

Through the window frame, Ye Yuyue saw a tall black shadow, but Ye Yuyue didn't see what the specific black shadow was.

On the other side, which was far away from him, Ye Yuyue saw an electronic door. There is an LED strip on the electronic door, which is currently displayed in red.

Thinking about the previous scene in the laboratory, it seems that as soon as the LED strip turns green, the door should be able to open. Then you should be considered to have passed this experiment.

At present, although there are animal stumps and severed limbs along the way, this factory is full of moldy machines that are still grinding meat. But he did not encounter real danger, is it really as the prompt says, this experiment is just a test of human courage?

Heh, what the hell is this experiment? Ye Yuyue muttered unconsciously. However, as soon as he finished speaking, he suddenly covered his mouth!

Because the thumping sound stopped with his voice!

Ye Yuyue hurriedly ran to the conveyor belt beside her to transport the corpse and squatted down, secretly staring at the wooden house.

Damn, how did you ignore that dark shadow!

After a while, a tall figure stepped out of the wooden house. Ye Yuyue couldn't help but gasp.
