Inside the dark cave, it seems that there is a dark world of its own.

The world seems to be boundless, full of death, and people are in it, they can't feel the passage of time, they can't feel the process of life, everything seems to come to nothing.

Bi Yu's physical strength had been restored, but under the erosion of this boundless dead qi, his physical body, which was as strong as his, was also corroded little by little, and his body and bones began to be filled with a large amount of dead qi.

In his blood, the rotten aura was even stronger, and it had even begun to turn dark red, and there was a little bit of gold mixed in with it, but it also turned into a dark gold color.

He had felt the cold, but then he had become numb.

He had felt hunger, but then it faded away and never came back again.

In fact, after reaching the Qi Madness, it has already entered the stage of Bigu, and it is okay to not eat for several months, which can be described as swallowing Xia and eating dew, and the body will naturally absorb the vitality of heaven and earth to supplement nutrients, so that the cells are full of vitality and will not feel hungry.

But in this cave world where only death qi existed, it seemed that there was nothing else, not even the vitality of heaven and earth, Bi Yu's body could not take in a little bit of nutrients at all, and he would naturally feel hungry.

Fortunately, Bi Yu's body was full of vitality, which was enough to sustain his life consumption, and he continued to fight against a large amount of dead energy.

Even in his vows or in the vows obtained from Ji Ning, there were many things that replenished physical strength or vitality, such as a large amount of pills, or some heaven and earth spirit grasses

These are enough for Bi Yu to easily get through the current difficulties.

It's just that Bi Yu didn't use these items.

He had a faint instinct that this was constantly invading the dead air in his body. If it can be familiar to his body, it can also be transformed into another special kind of energy. Like a yin thing, it doesn't need vitality. With the strength of the dead qi alone, combined with the power of the bloodline, it can be comparable to a human warrior.

This may be another energy system, if it can be used by him, it will definitely increase his strength, and this is very likely to be his last chance.

A chance to leave this cave of the dead.

This is just a conjecture, and perhaps in the end he will not be able to realize this conjecture, and it is likely that he will die until he dies.

Or maybe his body is really familiar with the death qi, and he can also use this mysterious power. But he has never been able to leave here again, and has become another new yin creature in this high cave of the dead.

But there is no other way, in this vacuum-like dead world, Bi Yu has nowhere to be forced, and he doesn't know where to leave.

If you want to survive in the unfathomable sea, you can only use the power of water to become a part of the sea and become a fish.

This seems to be an endless realm of dead air. It is the sea, and Bi Yu is to strive to be familiar with the power of water and strive to turn himself into a fish in this unfathomable sea water.

Every once in a while. The neutral voice of the Yin Emperor would come from far away, and the voice was full of bewitchment.

Bi Yu still couldn't hear what the other party said, but he was very firm. He is not subject to this temptation, and he will not give up on himself.

Such a desperate environment. It can make anyone's will go crazy and self-destructive.

But he Bi Yu won't. He was accustomed to such boundless darkness, because his heart was like this darkness, making loneliness an enemy and a friend of loneliness.

This situation has lasted for an unknown amount of time, and Bi Yu feels that a long time has passed, and the voice of the Yin Emperor has not appeared again.

It seems that he has forgotten him, and it seems that he feels it for a long time, but it is not long, because time has no meaning here.

Until that time, he felt like a fishing boat that had touched a reef in a shallow bay, and his body felt as if he had hit something cold, and all his numb senses slowly recovered from this impact.

All kinds of sensations tease the nerves and well-up in the heart, cold, hunger, weakness, pain, all come one after another.

He stopped floating aimlessly for an unknown amount of time, and this time, as if he had run aground, he stopped drifting with the tide and stopped for the first time.

"What is it?"

Bi Yu was puzzled.

Could it be that this boundless world of dead air is not empty of anything but dead air?

What did he hit?

He stretched out his palm to touch the cold unknown thing like a rock wall, and the feeling of his hand was like cold pig iron, but there was long grass like hair around him, and he couldn't touch the edge when he touched it up and down.

Bi Yu's eyes suddenly froze, and an unbelievable conjecture, a conjecture that made his heart beat faster, appeared in his mind at this moment.

"This is the strange place where I fell from the cave on the top of the mountain, here, the body of the king of the primeval tribes was buried, is it the body of the king of the primeval tribe that I leaned on in front of me?"

"But why, in this strange realm of dead air, there is not the slightest coercion?

Bi Yu's eyes gradually became blurred and empty, and his heart suddenly calmed down, and he entered a state of selflessness, feeling everything in front of him.

With the heart as the eye, in this dark and lightless world, we can see all the falsehood and all the real things that exist.

He saw it.

It was an unimaginable behemoth, at least with his spiritual sense that he could sense anything within a range of 300 zhang after entering the state of self-forgetfulness, he couldn't completely see the whole picture of this behemoth.

In his mind, there was a projection image, which was transmitted to his mind, which was half a huge body.

A human-like body, but incredibly large.

The part of his body that was close to him was near the behemoth's head, near his face.

The hairs were the body of such a man's gigantic creatures, like human hair, but each one was longer than his whole being.

"This is, the corpse of the kings of the primeval clans?"

Bi Yu was completely shocked, and he could only sense the abdomen of this behemoth from his current position.

Then how huge should the complete body of this primeval king, who has been dead for an unknown number of thousands of years, be?

A single hair was longer than his whole person, and his blue skin was as hard as pig iron.

Even in the middle of the forehead of the primeval kings, there was a huge horn more than ten zhang long, which looked like a small hill.

This terrifying existence, the part of its eyebrows, has a huge gap, three or four long and nearly half a meter wide.

A large amount of dead qi continued to escape from this gap, and there was a faint temptation in it that made the power of the blood veins in Bi Yu's whole body boil. (To be continued.) )
