The screams pulled Sun ruthlessly back to reality.

From the darkness of the night and the old man, in the blink of an eye, I returned to the underground cavern under Muinak.

The cell of the so-called "immortal".

Suddenly opened his eyes, Sun Wuru suddenly felt dizzy, and the familiar electronic sound of "friend" kept coming from his ears, but he couldn't tell what it was talking about for a while.

He should have authorized the "friend" to take control of his body in times of danger, and hopefully nothing will happen this time.

What's wrong with it? Could it be that the mysterious man has reappeared in this cave, blocking his connection with his "friends"?

But why are your ears filled with piercing screams?

Sun ruthlessly subconsciously took a step back, held his head, and blew his eyes, the soft light filled his eyes again, and he saw the cave clearly.

Su Duan was standing not far away, looking back at him, as if he didn't understand what Sun Wuru was doing. In his hand he held a transparent device that appeared to contain a crimson, viscous liquid. His hand was still on the side of the human face in the cave, and when Sun looked at it mercilessly, the face opened its mouth wide, its eyes widened, and a terrifying scream was coming from under the tongue that was as pale as a rock.

At the moment when he screamed just now, Sun Wuru, who approached him, suddenly covered his head in pain, and then retreated frantically, so that he could see the scene now.

"The connection didn't drop, but you didn't respond to me." The voice of "friend" finally reached his ears clearly.

"How long has it been?" Sun Wuru seemed to have just woken up from a big dream, and the memories that had pierced his mind just now immediately became blurred. He tried his best to grasp the dream, but countless details slipped through his mind.

"You stared at the face for twenty-three seconds." "Friend" projected what had just happened to one of his eyes and said, "Su Duan hesitated for a moment, and then stepped forward to collect the blood under the skin tissue of that human face with a blood collector, until it was almost finished, that human face suddenly opened its mouth and screamed. I wanted you to stop him. ”

"Collect...... Blood? Sun ruthlessly covered one side of his ear, watching Su Duan quickly hide the collector in his hand, and nothing had happened.

"It's hard to imagine that what is sealed inside this stone is really a creature." "Friend" began to study all the details of the man's face, the color, the texture of the skin, and the tongue in his open mouth, which, no matter how you look at it, resembles a human.

"Shall we ...... Go out first, his voice is so harsh. Sun Wuru didn't seem to have gotten rid of the dizziness he felt just now, and the scream made him uneasy.

"What the hell just happened?" The "friend" said: "I called you for dozens of seconds, and you didn't react at all." ”

"It's like, it's a dream." Sun Wuru's mind came back to the twilight, the white hamster, and the man with black-rimmed glasses who approached the hamster.

But he was about to lose his memory, and subconsciously, this dream was classified as a very important thing for him.

One thing not to forget.

"Listen carefully." "Friend" didn't care about Sun's merciless muttering, and a waveform diagram appeared in front of him: "His screams are not disordered, and the sound waves hide regular information. ”

"Friends" are quickly deciphering the meaning of this scream as if they had discovered a new continent.

"Can you let him stop first, it's been half a minute, doesn't he need to ventilate?" Sun ruthlessly frowned.

At this moment, Su Duan also covered his ears and came up.

The cave was small, the air was thin, and the carbon dioxide exhaled by the two made them breathe into

Rapid. Su Duan himself was very worried that the microorganisms or germs they carried on their bodies would interfere with the ecosystem here, and his move to collect blood just now was very bold, but the purpose had been achieved.

It's just that he didn't know why, just now Sun ruthlessly leaned his face over, and the human face opened his eyes, and the two of them were motionless.

"Are you still going to stay here? I'm ready to go. Su Duan's expression was very serious, and he didn't dare to take his eyes off the strange human face on the rock when he spoke.

Those eyes didn't seem to be looking at them, their mouths wide open and their eyes were facing the exit above their heads, and the voices in their throats never stopped.

It's like a cicada chrysalis stuck in a rock.

"Let's go." Sun Wuru was wary of Su Duan and kept a certain distance from him, and said to the "friend" in his mind: "What's the matter, I don't want to stay here." ”

"No results, it's not even the language or the password in the database." The "friend" can only throw out temporary results: "Some of the sound waves he emits are beyond the limits of modern human hearing, but they are mixed with low-frequency sound waves that only the skin can feel." There is a certain regularity, and if you want to express something, it must be a repetitive sentence. ”

"If there is no result, leave first." Sun ruthlessly looked up at the exit.

"If you want to go, you can go, when Su did his best to collect blood just now, I also took advantage of the chaos to do something." The "friend" controlled Sun's ruthless uniform, and the nano-level needle pierced the other side of the face at the same time, and through the dark side that the light could not illuminate, the "friend" also got the blood of this unknown creature.

Sun's ruthless suit ejected the blades and suction cups used for rock climbing, and around them it was just ordinary rocks, and it was easy to climb up.

And Su Duan turned out a strange ladder from his backpack, nearly two people high, attached to the rock like an octopus, as Su Duan climbed, the bottom alloy plate shrank to both sides, and then passed to the top, just to catch Su Duan's hand.

In just half a minute, they got what they wanted from the cave. Sun Wuru was still trying to recall the dream just now, and his brows were furrowed.

But at this moment, Sun Wuru suddenly heard a clear human voice.

"Data is everything."

He struck a stirring spirit in an instant.

Countless memories came to him like a sea of memories, but what frightened him even more was that he was no longer in the dream world.

"Friends" also heard this phrase.

Sound waves came from beneath them.

At the same time, Su Duan, who was climbing up on the other side, also stopped. But he didn't look at Sun Wuru, but like him, stared at the face not far away.

I don't know when, the screaming stopped. Instead, there was a clear life, which passed into Sun Wulu's ears.

Those were conversations, they were memories, two voices that were very familiar, and they were also memories that he had lost.

He listened intently, and Su Duan didn't seem to have the same content as he listened, but it also attracted his attention.

"Data is everything?" "Friend" asked, "He's speaking Federal?" ”

"Shh Sun Wuru just wanted to listen carefully, but found that his voice suddenly weakened.

He leaned forward slightly.

But the next moment, the rock wall on which his hands and feet were resting shattered.

Very suddenly, very ordinarily broken, the structure inside seemed to collapse suddenly, and it was only limited to a very small piece, which happened to be a few of Sun Wuru's focus points.

The same happened to Su Duan. His ladder began to fall entirely, and the suction cups on the stand shattered into the rocks

Dust.

The entire rock wall seemed to turn into a fragile building block, and as the two of them fell to pieces, Sun Wuru couldn't keep his balance at all and fell back to the ground.

But the ground doesn't seem to be as hard as it was just now.

"This ......" Sun stood up ruthlessly, and there was black sand flowing down between his fingers.

"What's going on? Is this sand? Su Duan fell next to Sun Wuru, and the expression on his face was very puzzled.

None of them noticed that the sound that had been echoing in their ears had stopped again. The whole cavern was silent, but in their eyes, it was completely different from what it had been before.

The strange atmosphere gradually spread, and the two of them had not been able to climb up for ten seconds, but the hard rock they had been standing on just now turned into a fine sand at some point.

"Look back, quick!" "Friend" is always the one who responds the fastest, but it also has to be analyzed with the help of Sun's ruthless eyes.

Sun Wuru turned his head for the first time, but before he could see the face on the rock wall again, the light in the cave flashed, and the entire vision suddenly fell into darkness.

The battle uniform on his body instantly moved, the black battle armor wrapped Sun Ruthless's whole body, and in the green night vision device, they were facing an ordinary wall. The face was very similar to the texture of a rock, and it would be difficult to distinguish if it was still or without light.

But the "friend" still used big data to mark the location of that face, and now, it is motionless.

There was no wide mouth, no shrill screams, and it fell silent again, as if nothing had happened before.

"What's going on?" Su Duan repeated in the darkness, and Sun Wuru heard the sound of mechanical iron colliding from his direction. He was clearly still wearing enough gear to handle all the changes, and perhaps a gun capable of killing.

But Sun is ruthless and fearless, the armor he wears is the latest model of the Federation, almost completely isolating the user from the outside world, and the inner mezzanine is equipped with microrobots and various knives. Just now in the cave, neither side would make a move easily, but they also maintained a distance of more than one meter, just to understand that the two still had a back hand for each other.

"I don't know." Sun replied ruthlessly and simply, intending to stand up.

This cave is only ten meters in circumference, which is almost a face-to-face distance for two people, and it is not as big as a boxing ring.

And among these four rock walls, there is only this strange human face.

According to Su Duan, this is the strange creature that the ancients dug up here thousands of years ago?

"Before coming down, the elders told me that no matter what you encounter, you can't resist hard, find a way to run." Su Duan is debugging a new escape tool.

"I'm worried about the haunting of this place right now." Sun Ruthless also has a small gliding booster on his armor, and I wonder if I can help him get out of this cave.

"It's not a ghost." Su Duan shook his head, and there was no fear in his tone: "This is a prison cell, not a grave." ”

"What if that thing is dead?"

"He can't die." After saying this sentence, two blue flames suddenly lit up at Su Duan's feet, and he even carried fuel on his back.

But the next moment, the wind blew.

There shouldn't have been air convection in the cave, but both of them felt a thrust coming from behind them at the same time. The black sand under their feet was not strong at all, and the rocks in their hands shattered at the slightest touch, and they suddenly found themselves like small fish in the sea, and a huge torrent was coming towards them.

And the direction they were being pushed in was where the strange human face was.
