I am immortal with scientific thinking

"Underground space?"

Lin Chen's eyes moved and he said:
"But this villa has a second floor underground?"

"No..." Su Mu's expression turned ugly at this moment, and he handed the electronic screen over, "Look for yourself."

The latter frowned slightly, reached out to take it, and looked at the screen.

The screen was completely dark, and it was hard to tell what was going on. But in the darkness, I could vaguely see a scene. It was a place...

Cave?

"This is the first time I've seen a cave underground." Lin Chen narrowed his eyes and observed it carefully. With a hint of surprise between his brows, he said, "It's just that the light is too dim, and it's not very clear."

"No matter which one it is, it proves one thing. There is indeed something wrong with these guys!" Su Mu's face showed a stern murderous intent. He looked at Lin Chen and asked, "How about we go down and find out what's going on?"

“Since we’re here, it’s inevitable. However, the connection below can actually be blocked. You know, we use the most advanced quantum communication. There may be the core of a supernatural disaster or the influence of the power of an alien universe below, so just in case…” Lin Chen’s expression turned cold.

Then, he took out the satellite phone again and entered a string of keys:
"As long as the satellite above cannot receive our quantum signal after twelve hours, the nuclear bomb attack will be launched at the same time!"

"You really are..." After hearing this decision, Su Mu didn't know what to say for a moment. After a moment of silence, he said, "In that case, let's go."

"Walk."

As soon as the words fell, the bodies of the two people began to fade little by little, until finally, they completely turned into colorless and transparent existence.

This is one of the black technologies they have deployed - optical camouflage.

It is a black technology that uses advanced materials and technologies to achieve the invisibility of objects or human bodies. Its core principle is to use nano-level optical materials and the epidermis of evolved organisms to capture the light information of the surrounding environment in real time, and through projection or refraction technology, the surface of the object is completely integrated with the background to achieve a visual "disappearing" effect.

The inspiration comes in part from the camouflage abilities of certain animals in nature, such as chameleons and octopuses, which have evolved significantly in the catastrophe of evolution.

After confirming that there were no cameras inside or outside, the door of the room was opened and closed silently, as if no one had entered or left, but there was no figure in the room.

As the micro drone explored, they quickly followed a fixed route, bypassed the survivors of the base, and came to an extremely remote corner.

"Is this the place?" In the communication channel, Lin Chen frowned as he looked at the wall in front of him, then turned to Su Mu beside him.

"That's right." The latter took a step forward and gently drew a circle on the ground with the laser knife.

Suddenly, the ground in front of me caved in, revealing an extremely dark hole.

There was darkness below the cave entrance, which made people feel inexplicably uneasy. There was deathly silence below, without any sound at all. Even the light of a strong flashlight disappeared as soon as it touched, as if it was silently swallowed up by the darkness.

"Walk."

Without any hesitation, Lin Chen led the way and jumped directly into the dark tunnel that was like a worm's mouth. Su Mu followed closely behind him.

When the tip of his foot touched the ground, Lin Chen felt a soft feeling, like soft jelly or rotten meat paste. When he exerted force, his foot began to sink, as if he had stepped into the corpse of a giant and was absorbed by the greasy fat... This is flesh and blood, this thought flashed through Lin Chen's mind.

"Achen, are you okay?"

In the darkness, Su Mu grabbed him and turned on the high-intensity flashlight in his hand.

However, a flashlight that can penetrate several kilometers in the darkness seems to disappear when the light is shone through it, and only a dim light can be vaguely revealed, illuminating only a few meters around.

"This is not a cave at all..." Su Mu's face changed when he saw the scene clearly.

Under the dim light, everything around looked like pale, raised lava, but it would return to its original shape when stepped on, and it was obviously elastic... It felt like this was not a cave tunnel at all, but rather the body of some creature.

He looked up and saw darkness above him. Even with a strong flashlight he could not see anything. He could not find the entrance to the cave where they jumped into. It was as if they had come to this strange world since entering the cave.

"These things are not risky for now, the real trouble is something else." Lin Chen also held Su Mu's arm tightly, and the two of them leaned against each other tightly. In this environment, being alone is the same as death, so they can't separate no matter what. "Did you hear any sound?"

"Sound?" Su Mu's face sank. After he calmed down a little, his expression suddenly became even uglier.

The strong impact of the alien environment and the indescribable discomfort and awkwardness that made his body subconsciously feel, but at this moment, he also vaguely heard a voice.

No one knew where this sound came from. It was very subtle, yet it was everywhere. It gave people the feeling that countless people were hiding in the dark and whispering. All kinds of incomprehensible strange syllables and sounds seemed to be the most sinister curse from the underworld. One could not understand it, yet one could feel the deep malice in it.

Even if they didn't listen, the sound was like a wriggling parasite, trying hard to drill into their minds.

And as these sounds entered their bodies, their minds inevitably began to be filled with anxiety, irritability, fear, and even hysteria.

The reason why people are called people is because joy, anger, sorrow and happiness coexist. But what will happen if a person only has negative emotions such as fear, hatred or anger, and fear only makes people more afraid and anger only makes people more angry?
If we compare a person to a bottle, negative emotions are nails or charcoal thrown into it, and positive emotions are the things inside the bottle that slowly repair it.

But if you just throw burning charcoal into a bottle, it will not be clean at all. What will happen if you still try to stuff more stuff into the bottle when you know it is full?
There is no doubt that breaking will be the only ending for this bottle.

"Trouble..." Su Mu tried his best to relax at this moment, but the feeling of mania and uneasiness still inevitably rose.

In this dangerous and strange environment, rational thinking is the key for intelligent creatures to break through. However, this voice that comes from nowhere will continue to add to their negative emotions. When faced with real terror, with their moods fluctuating greatly, they may easily make suicidal decisions. After a long time, they may collapse without even encountering danger.

After all, physical collapse means death, and mental collapse means "suicide," which is something that all children understand.

"Achen, do you have any heart-clearing spell that you can use? Perform it for me quickly!" Su Mu realized this instantly and quickly transmitted the message.

"Yes, there is, but it doesn't work. This is the influence of supernatural factors. In this environment, simply chanting spells will not work." Lin Chen's voice came from the communication channel, "So don't hesitate, before the negative emotions completely erupt, find out the situation here, and then use high-energy bombs to escape!"

"...Okay." After a moment's silence, Su Mu nodded.

Soon, the two of them were like stepping into a quagmire, supporting each other, one in front and one behind, one deep and one shallow, walking deeper. This tunnel seemed to be endlessly deep and far, and there was no end. After groping in the darkness for nearly half an hour, there was still a long corridor in front of them, as pale as the skin of a dead person.

"Damn it, where on earth is this place?!"

No matter how relaxed he was, there was a constant noisy sound echoing in his ears, just like when you were still asleep in the early morning, with renovations happening upstairs and singing and dancing downstairs. Su Mu could hardly suppress the rage in his heart.

The current environment is so creepy.

Although there was dead silence all around them, it seemed as if countless people were whispering in their minds.

This weird and contradictory feeling makes people feel as if they have entered an unknown hell, where countless evil spirits are spying on the living people from the darkness in the shadows.

"If you are very upset and can't hold it anymore, just go and channel it. Sometimes the sage state can allow you to make calm judgments under the accumulation of negative emotional pressure." Lin Chen gave a very useful suggestion.

Then, he looked at the pale, yet smooth, soft wall that looked like the skin on the back of a person:
"In theory, with the help of the exoskeleton armor, we have traveled at least ten kilometers in the past half hour. No matter if this is the inside of a monster's corpse or an underground cave, we should be able to see something different, instead of the dark tunnel that has no end like now."

"If I'm guessing correctly, it's the way we're moving that's wrong."

After hearing Lin Chen's suggestion, Su Mu thought about it carefully and felt that his inner irritability seemed to have faded a lot at this moment. He looked at the wall beside him:
"Do you suspect that this is just a means to mislead us? The real key to exploring this place is on this wall?"

"That's right." Lin Chen replied.

Then he took a step forward, stretched out his hands, and touched the wall.

Lin Chen had not taken any action before because he was worried about something unexpected happening. But now that he had not found a way out, he had no choice but to give it a try.

Who knew that with just a touch, his hands would be sunk into the wall.

"Ok?"

Lin Chen frowned and stretched out his hand. At this moment, he saw that the flesh-white wall in front of him was scraped off layer by layer of white sticky substance like lard that had been frozen for a long time.

When these were removed, a very textured, slimy and flesh-white wall was revealed.

It is very unique, bulging as if it has life. There are things like pipes connecting one node after another that emit faint light. It looks indescribably weird.

However, Lin Chen did not pay too much attention to the pipes and nodes inside the flesh-white wall. Instead, he was attracted by its surface.

All kinds of strange and bizarre symbols were depicted on it, forming a bizarre and strange content in a pictographic way.

The first mural looks like a city, with several overlapping rectangles that resemble tall buildings, and several human-shaped symbols walking among the tall buildings.

Then, it was like an ancient sacrifice being carried out in a dark room, with all kinds of evil and cruel ritual scenes. If you pick out any one of them and film and restore it, they would be banned films all over the world, full of madness and disgusting.

Then a group of people gathered together, seemingly discussing something, and outside them, the entire city seemed to be in a fire, and in the flames, there were strange shadows approaching.

In the end, it is a very terrifying picture, even the flesh-white wall is given a dark and uneasy color.

Dozens of fresh human brains, black, white, and mixed with colorful unknown fluids, seemed to be aggregated in a laboratory.

On top of each brain, there are metal electrodes inserted, as if they are integrated with the flesh and blood of the brain. The protruding brain tissue extends dense granulations, like plant roots made of flesh and blood, covering the metal patches.

In this picture, each brain is like a starving beast, sucking electricity greedily.

Under the influence of an unknown force, these brains maintained amazing activity and seemed to have transformed into an independent creature. A structure that should not appear on a human brain grew out of their brain grooves. An extended tentacle connected to a throbbing fleshy protrusion, which seemed to be the sensor organ of this "creature" called "brain". They would pierce the fleshy protrusion into another brain, and then the two brains began to blend together in an inexplicable way...

These strange and terrifying pictures challenge the most basic understanding and cognition of human beings. Su Mu felt that his brain seemed to be trembling violently at this moment, and he vaguely heard sneaky movements coming from deep in his brain, as if an insect pupa that should not have hatched was quickly hatching and breaking out of the shell under this mysterious influence.

At this moment, all the scenes in front of his eyes began to disappear rapidly. When light and darkness intertwined in his vision like a crazy dance, Su Mu found himself being drawn into an endless abyss. It was like a black field formed by the edges of the starry sky and the underworld, very desolate.

There is an inaudible movement in this desolate wilderness, a rustling sound, an almost forgotten whisper, a secret symphony hidden in the darkness. The friction sound is not the breeze, nor the rolling of stones, but more like ancient tentacles sliding quietly in the void.

And around this wilderness, there stood... twelve figures.

They are hazy and distorted, and their bodies seem infinitely large, yet extremely small.

Tall and strong, thin and weak...all kinds of contradictory concepts are distorted and condensed in one body. The face is blurred and the appearance cannot be seen at all. It seems that it is an indescribable existence composed of countless symbolic objects.

Su Mu just felt like an ant that had strayed into the wilderness. In the eyes of every predator, he was a novel delicacy and a toy.

Under the indescribable gazes of those figures, the horrifying aura, countless whispers, and all kinds of bizarre images rushed into his mind.

His flesh and blood dissolved at this moment, and his soul quietly collapsed without knowing when. However, his heart felt unprecedented joy at this moment, as if he had merged into those indescribable figures, which was his lifelong belief and pursuit...

But at this moment, at some unknown time and from nowhere, an extremely firm voice suddenly came:
"We...are human!"

In an instant, in this endless and silent wasteland, the voices of countless people rang out at this moment.

There were men and women, old and young, near and far, high and low, like sparks of fire, overlapping at this moment, completely resounding through this deadly wasteland:
"We...are human!"

"No... a monster!"

"This is... our world!"

In an instant, the world spun. (End of this chapter)
