The passage was not long, and in a space that was almost circular, Zhuge Yun detected something interesting.

They are located in a place enclosed by many curved walls. There was a faint smell of burnt air in the air, which smelled fresh, ozone that had been electrolyzed.

The hot air blowing from the bottom of the cave is coming from a short distance ahead.

From above, it should look like a mosquito coil, with a coiled wall built around something in the middle. There was a thick layer of dust on the ground, Zhuge Yun rubbed some of it and identified it carefully, and couldn't help frowning.

It's unclear what the dust is left behind after it burns.

"The host, I sense, is ...... It seems to have the breath of blood! Avanna pulled out her shiny silver sword from her back, adjusted her breath, and prepared for the emergency.

"yes, I know."

Zhuge Yun's face was still calm, although he had already felt the residual breath of the blood clan, he also had doubts in his heart.

This place was obviously built by pre-civilized humans, but why does it have anything to do with the Bloodline?

Zhuge Yun continued to explore the entire space with his divine sense, and finally he found something, floating silently above them.

It was a dull black polyhedron, about 2 or 3 meters in diameter.

He flew up silently, but when he reached a certain height, he stopped, because he suddenly realized that the space around the thing was filled with rays that could be excited in an instant.

What is the reason why the weapons of pre-civilizations were put here to destroy the rays of biological cells?

He is also familiar with this kind of thing, and it was equipped on the original "Pacific". This ray can kill the cells of all living organisms in 10 seconds, and the goal is achieved by exhausting the organs of the body.

Zhuge Yun smiled faintly, now he is not afraid of this ray, as long as he uses some means, he will enjoy the satisfaction that this energy brings him, just like bathing in the sun, it will not affect him in any way.

He stopped because he was thinking about something, how he could get that tremendous energy.

These things are suspicious here, the polyhedral device on the top wall is still running, countless rays coming out of the various emission holes, intertwined like infrared rays into an invisible net, their role is obviously to protect the thing hidden in it.

Not to mention what's in that thing, the purpose of these cell destruction rays is very elusive, and it seems that it is a defense mechanism set up to keep that thing from the outside world.

Such a rigorous and astonishing energy response suggests that there should be a long-term power supply here.

He guessed that the power supply equipment should be a device that uses small nuclear energy, which continuously produces energy and drives those cell-destroying rays to work for a long time, but he doesn't know how many years it has been running.

In this way, the place is like a well-defended "prison". Just don't know what's imprisoned?

Just as Zhuge Yun was thinking, he heard Avena exclaiming: "Master! It's a blood clan, and there are a lot of blood clans down there! ”

Sure enough, Zhuge Yun looked in the direction of her finger, and under those surrounding cement walls, there seemed to be a layer of transparent crystals on the ground, and the outlines of some figures were revealed through the places where the crystals were not covered by dust.

This was discovered by Avenna while patrolling the air, and the occasional reflection on the ground made her sense that something was underneath.

There were many bloodlines side by side underground, not too deep, arranged around a circle, their heads all pointing to the center of the circle, as far as the eye could see, almost 6 or 7 circles, but some of the positions were empty, there were no bloods, roughly counting about hundreds of bodies.

This discovery shocked Avenna, who had no idea that so many survivors of the Bloodclan were buried here.

Who put them here? What is its purpose?

Zhuge Yun was still thinking about those energies in his heart, and continued to raise his head and investigate carefully. This irregularly shaped thing, like a metal polyhedron, is locked in layers by layer, and the surface is pitch black, and no reflection can be seen. In terms of material, it is fundamentally different from the creations of the previous civilizations below, like some kind of black crystal.

Seeing it, the corners of his mouth grinned, and he couldn't help but smile faintly.

He wasn't unaware of the origin of such things, as he had seen them as tall as mountains on the surface of that strange rock planet when he was traveling on the USS Pacific.

"Obsidian Crystal" is the name of this substance, the creation of the "Is", a great race capable of time travel.

The Isis have crossed the galaxy of the universe and come to this planet from the destroyed world known as the Istin.

They exchanged the consciousness of the entire race with the native race on the planet, and obtained the physical body that acted on it. They ruled the Earth for a long time, until they were defeated by the Flying Leeches and destroyed their huge black city.

They like to use these smelted dark crystals to build their buildings, which is also considered a "man-made" metal.

It's just that it's obviously a bit unreasonable to find these things here.

Without any surprise, after trying it, the detection of the divine sense was reflected back. But he knew that it was not because this thing could isolate his divine consciousness, but because his divine consciousness level was still too low and his spiritual power was not strong enough.

There's definitely something in there, that's his conclusion. It seems that if you want to know what is hidden inside, you can only get the answer from the hidden bloods below.

Zhuge Yun quickly descended again, and the aura emitted by his body instantly blew away the dust on the ground, as clean as if it had been washed, and the bodies of the blood clan below could be clearly identified.

Each of the Bloods lies in a "coffin" made of cast steel, and some sophisticated instruments connect to the ground from the inside of the coffin and converge in one direction.

Zhuge Yun couldn't help but smile dumbly after probing for a while.

Because he found that these bloods were apparently providing some kind of "energy" to the dark crystal wrapped thing above, and there was an energy collection device nearby, which was still in operation, and this energy conversion device was also powered by a small nuclear reactor buried underground.

He floated over, his palm outstretched, and a blue light emitted on the energy-harvesting device, cutting off the energy supply. Then he flew up to the top wall and inspected the surroundings of the dark crystal for a while.

"Buzz!"

Under the urging of his spiritual power, the outer wall of the black crystal rippled like flowing water, faintly revealing a blue-black light.

Continuing to increase the infusion of spiritual power, the polyhedron began to rotate slowly, and circles of blue streamers reflected in the space and became faster and faster, and the black surface began to appear transparent.

"Oh my God! There's ...... Something seems to be there? Number 17 stared at the polyhedron that was getting clearer and clearer.

Seeing through the surface layer of the black crystal that is nearly half a meter thick, it seems to be a strange sitting bleak body inside? But it's blurry, and you can't see the details in the shadows.

Although the speed outside had reached nearly 1,000 revolutions per second, the figure in the inner space was not affected, and it stood still, as if it was suspended in it.

"Bang Bang Bang-" After a few crisp sounds, the outer layer of the black crystal began to thin, and the blue glow was already intensely reflected in all corners of the hall.

Zhuge Yun's face was expressionless, and he couldn't see what he was thinking at the moment, but the spiritual power shield around his body had already opened. While seeing what was inside, he felt a huge amount of energy gradually leaking out, and the index of biological fluctuations was rising sharply.

Is this the one who has been hidden by the Bloods or pre-civilizations?

Many questions hung unresolved in Zhuge Yun's mind.

"Kalala-" There was a sound like a giant tree breaking, and the black crystal polyhedron couldn't withstand the tremendous pressure, and the outer layer peeled away like gravel.

One of Zhuge Yun's hands stopped instilling spiritual power, followed by a squeeze of his palm, and the rotation stopped.

The huge black polyhedron was about to crash to the ground, but it was lifted by the spiritual power giant and landed steadily a few centimeters from the ground.

"Bang dang!" All the dark crystals shattered from the surface, and the figure inside was fully revealed.

With long silver hair, an old, emaciated face, eyes tightly closed, sallow skin on his body, and a gray strip of cloth around his waist, he looked like an old man who was too old.

He sat there cross-legged like a statue, motionless, as if he was still asleep, perhaps wandering into the world......

But his body was so special that half of it had vanished—a cloud of void energy like a black flame, to be exact, that consumed half of his body.

This turned out to be the energy of the black evil!

I don't know how long the black evil energy has been embodied in this body, but he is still alive by the black evil body, which makes Zhuge Yun feel a little surprised.

"Who is this, who is this man? Is he alive? Avenna said as she tried to get closer and take a look.

"If you don't want to die, don't go over......" The indifferent voice came, and Avenna was frightened and hurriedly stopped.

Zhuge Yun's divine sense probed his body for a while, and realized that this black evil energy was bound by a larger energy, so that this person's body was now free from the real space and the endless void.

Suddenly, an abnormal fluctuation came, Zhuge Yun condensed his spiritual power to protect his whole body, even if he had a huge computing power, he didn't have time to deduce where this fluctuation came from.

But in his mind, he received a message, and it turned out to be ...... It was the old man who was talking to him.

"Who are you?"

The old man's expression did not move at all, he was still sitting quietly like a sculpture, communicating with him in a way that Zhuge Yun was familiar with spiritual communication.

"Hmph, your question is too general...... Why don't you tell me first, who are you? Why did it look like this? Zhuge Yun said coldly and arrogantly, not taking the other party in his eyes at all.

The old man was silent for a long time, as if he was thinking about Zhuge Yun's question, but there was no answer.

"Well, it's strange that you're not a mutant, and you're not a member of my clan, so you can't see where your abilities come from." After a long time, the old man finally spoke.

"Heh-it's okay if you don't want to say it happily, then I'll drain the spiritual power of your whole body, find something to pack you up, and continue to hang it up." Zhuge Yun's cold eyes stared at his sallow face, and said seriously.

"Hmm...... Well? You actually know spiritual power? The old man was a little surprised this time.

"Okay, stop talking nonsense, tell me about your situation." Zhuge Yun's hand had a blue glow.

"Wait, you're supposed to be a human in the world, right? Your foundation is strong, why don't we make a small deal? ”

Zhuge Yun was silent, just sneered, looking at him here to rely on the old and sell the old, when will he pretend. He was already a little impatient, and the blue light in his hand was getting bigger and bigger, as if he was about to reach out and grab the old man's body in the next second.

"Good, good! Don't do it, I said it's not okay yet? ”

The old man also saw that this young man was not bluffing, but also a ruthless character who was decisive and decisive. Although his body was still unable to move, he was already afraid.

Zhuge Yun snorted coldly, but there was no sarcasm in his mouth, he had already seen that this old man was trapped here.
