Under the light of the flashlight, the blood-colored red silk made the orcs' hearts beat.

There was too much blood on the floor of the spiral staircase, and without the special uniform on their body to isolate the air, the orcs would have no hope for the ruins below.

The orcs walked all the way for half an hour.

During the long spiral descending the stairs, the orc turned too many times, felt dizzy, and had the illusion of a double image in front of his eyes.

The soldier cautiously reported to Allen, thinking that it was a minor situation, but he did not expect Allen to attach great importance to the mental state of the soldiers.

"Ten minutes of rest." Alan said over the walkie-talkie.

The orcs stopped very tacitly, rested for ten minutes, sat cross-legged and practiced morning exercises, and visualized the sunrise over the sea, and the body and mind were at ease, and the orcs went down the stairs again.

This time, I walked for twenty minutes, and finally came to the final starting point of the spiral staircase.

In front of me was a closed red door, the red was too dense with blood, causing the door to appear red.

Ivan pointed the gun in his hand at the door, and slowly touched the door, and the door slowly slid open from the middle with a buzz, and the dense red silk was torn from the middle.

He immediately moved to the right, making room to avoid blocking the gunline, and Eren used his sonic skill to probe inward.

Although the soundproof suit is soundproof, it is not 100% soundproof, as long as a little sound leaks in, Alan can use his skills to analyze the terrain in the distance.

After a second of analysis, nothing resembling an alien creature was heard.

The flashlight illuminates the inside of the gate, and the ground is covered in blood!

The bloodshot inside the door is different from the outside of the door, and the bloodshot inside has become thicker, like twisted blood vessels, intricately entangled, like a chaotic labyrinth, and like an evil place.

"This ......"

"Suddenly I feel a lot more terrifying!"

The orc's hand holding the gun subconsciously increased its strength, and his mentality was slightly nervous.

"Attention, everyone, the echo is gone." Alan was keenly aware of the unusual nature of this place, and hurriedly used the identification technique on the thick "blood vessels".

Bite.

The identifications are as follows:

[Organ of a carbon-based organism]: This is one of the organs of a carbon-based organism that exists in this ruin, which can secrete hallucinogenic biological pheromones and absorb air energy......

The results were similar to those when Alan was at the Tomorrow City Bio Laboratory, and it seemed that it was something of the same species.

"Everyone should be careful, maybe the owners of these blood vessels are still alive." Alan put the blood vessel in his hand into a small sealed bag and kept it, calling it "blood vessel" for the time being, and took it back to the biology laboratory to study it later.

"Roger." The walkie-talkie rustled for a second.

The orcs stood in the doorway in a group formation to protect Eren.

The light of the flashlight hit the front, and the empty secret room was illuminated by the light, empty and deep, and blood-red.

Step by step, the orcs stepped inside, the sensor door behind them humming shut.

The orc who was standing behind to prevent a sneak attack had a flustered look in his eyes, his breathing became heavier, and he said, "Your Majesty, the door is closed." ”

"Go back, can the guard door still be opened?"

"Yes, Your Majesty."

The broken orc walked back to the gate, and the red silk gate slid open again, and the scarlet spiral ladder was still there, leading to the top.

Seeing that the sensing function of the gate was not closed, the broken orcs tightened their formation and returned to Allen's team.

The veins all over the ground are like the roots of old trees coiled together, it does not beat, like a knotted dead thing, lifeless, but it makes the orcs nervous.

As they got closer, the orcs noticed that the blood vessels on the ground were getting thicker and thicker.

"Your Majesty, Number Four has found a large blood vessel that beats!"

The orcs heard the rustle of the walkie-talkie, and the nerves in their brains tensed, and slowly approached the location of Number Four with their guns in hand.

I saw a blood vessel thicker than his thigh next to the sole of Four's foot, and the blood vessel shuttled through the kink of blood vessels, stretching into the darkness in the distance.

Alan approached and saw the walls of the vessels slightly expanding, contracting, and expanding again, like breathing blood vessels.

He looked at the vein, and with his sonic skills, heard a subtle throbbing sound.

It was because Alan listened carefully to the beating of blood vessels that an illusory scene gradually appeared in front of him, a giant tree made of countless giant blood threads, rooted in the pitch-black black pool.

There is a fluorescent lamp on the ceiling above the giant tree, and the wall of the lamp tube is full of bloodshot attached to the surface, causing the white light to penetrate the blood, dyed with a red blood, magical and oppressive.

Alan blinked, activated his inner exercises, eliminated mental interference, and the illusion in front of him disappeared immediately.

"Its voice is hypnotic, don't listen to it." Alan looked around and shone his flashlight on the soldier's transparent hood.

The orcs were shaken, but their eyes were still normal, and they did not appear to be sluggish.

"Yes, Your Majesty."

They are not deeply affected, the soundproof clothing has isolated most of the sound, and if the small sound is not listened to, the attention will not be mobilized.

Alan looked at it carefully for a while, it was very tense, it was by no means a dead thing, but a part of a living thing.

If you follow this giant vessel, you will probably find the giant red tree that appears in the illusion.

But Eren didn't leave immediately, he was thinking about whether to take the risk.

"The owner of this blood vessel may be a living mutant tree species, you still remember the genetic medicine we brought out from the ruins last time, our biological laboratory has measured a medicine that can transform animals into plants, and the original owner of this blood vessel may be like that."

"Our institute has not been able to make the animal mutation successful, but the owner of this blood vessel may be a successful product, the degree of genetic modification is much higher than ours, if you see it, shoot it immediately, don't hesitate."

"Yes, Your Majesty." When the orcs heard that the owner of this vessel might be alive, they were even more cautious.
