In the gray world, there is no other bright color to be seen, and this hollow and incomparably lonely feeling is enough to make any normal person go crazy.

Chen Han walked on this gray land, and a sense of despair and depression tormented his spirit all the time.

This world seems to have no end, there is no living creature in sight, and there seems to be only one living creature on the entire vast land.

Chen Han had almost no understanding of this so-called Black Prison Netherworld, although he had asked some other people before, at most he could only know what kind of place this was, but he really didn't know what to do.

Chen Han's footsteps are getting faster and faster, and there is no restriction on his own cultivation in this world, but Chen Han originally didn't dare to exert his strength too quickly, for fear of encountering some powerful existence.

But under this boundless scruple and desolation, Chen Han would rather encounter some powerful beings who could not be defeated than be driven crazy in this sad world.

The cyan sword light quickly swept through the sky, and as soon as it was stirred by the cyan sword light, the gray-black mist seemed to ripple in bursts.

Chen Han didn't hesitate at all, he just wanted to see something else in this gray-black world now, even just the most ordinary things like stones, grass, trees, and sky.

But no, he almost used up the spiritual energy mana in his body, but he didn't see anything he wanted to see, and the world that appeared in front of him was still that gray-black boundless haze.

Chen Han's originally fast-flying figure no longer moved, he sat in this gray-black world, there was no gravity and suction, up and down the four directions, no matter where he went, all he saw was this gray-black, in this case, it was better not to continue to waste the mana and aura in his body.

As for how to get out of this Black Prison Netherworld, Chen Han naturally asked carefully before, similar to the military world, the souls who enter here and do not belong here can only exist for a certain time, so they will exit the Black Prison Netherworld by themselves, and each soul in this place can only enter once, so this time the Moko Ghost King has no chance to come in.

Chen Han's eyes were closed, and when he wanted to recover the mana that he had consumed by flying through this world quickly, he was surprised to find that although this piece of heaven and earth felt rich in spiritual energy, it was very different from the spiritual energy he cultivated, and it was very similar to the yin power ghost qi of the reincarnation star sea, but it was only very similar, but it was not at all.

This is a special energy aura that has never been seen before, Chen Han did not rush to study this thing, but took out a few pills from the Upside Down Realm and swallowed them, and the true qi consumed before was quickly replenished.

After Chen Han tried to absorb some of this gray gas and entered his body, he suddenly felt like a mortal had eaten something bad, and the feeling of dizziness hit him all of a sudden, not only on the body, but also on the soul.

Where did Chen Han dare to hesitate, and hurriedly expelled this power from his body.

However, this gas energy Chen Han only absorbed a trace of it, and there was such a big reaction.

"Could it be that this is really a small cave left over from the last civilization? The energy retained here is the power structure cultivated by the monks of the previous era? It's completely different from Reiki. ”

Chen Han didn't feel how to hate this breath, but was quite interested.

He was born on Earth, and the idea of these things was very different from that of ordinary monks.

Chen Han didn't know if the cultivators of the previous era were cultivators like them, or even if they were human beings, even if they were human beings, the structure of their appearances, the transformation of laws, and the difference between heaven and earth should have a situation that was incompatible with the present.

But if the humans of the previous era were the same as them, then the monks of that era could absorb this power, so why couldn't they themselves?

Maybe it's just the reason for the exercises?

Chen Han thought of a possibility.

Chen Han didn't continue to speculate, after all, it was naturally impossible for him to possess the exercises of the previous era, and he didn't even know the cultivation system, let alone create one.

Chen Han didn't use the cyan long sword condensed by his own true qi, but casually took out a top-grade flying sword that had been absorbed.

He didn't continue to absorb the gray air into his body, but instead channeled it into the body of the long sword in his hand.

He didn't refine this sword, and naturally he couldn't control it freely, and his mind was connected, he just used the long sword in his hand as a container to absorb and accommodate this gray air flow.

Sure enough, compared to the discomfort in his body, this power didn't seem to have much resistance and discomfort for entering this sword body, and Chen Han didn't see how this sword was, but instead had a more dangerous aura than just now.

"It's harmful to the human body, but it's not half harmful to these magic weapon blades, but it will make the power stronger?" Chen Han nodded, and then picked up the long sword, but as soon as he touched the hilt, as if he had been burned, he immediately let go of his hand and threw it away.

As soon as the gray-black air flow absorbed by this long sword felt his breath, it frantically surged towards his body.

Chen Han's originally white jade-like fingers turned gray-black in just this instant, as if they had been poisoned.

Chen Han's face remained unchanged, the mana aura in his body surged, expelling the gray-black wisp in his hand, and then wrapped the long sword in front of him with his self-aura, and then separated a trace of spiritual power, and after protecting it with majestic aura, this trace of spiritual power dared to reach into the body of this sword, and observed carefully.

A special material vein, although this sword weapon was taken out in the military realm, but the Huanyu Furnace was originally an incomparably powerful artifact-level thing, and the blade that was refined was no worse than any great master of refining.

The structure of this long sword was extremely fine, and the layers within the sword body were distinct, but when Chen Han probed his spiritual power into it this time, he found that the middle of the sword in front of him had been completely hollowed out, and it was occupied by that gray-black air current.

But even so, this sword was not broken because of this, but Chen Han felt it very clearly, the power of this sword was at least twice as strong as before.

It's a pity that he can't control it, even if Chen Han wraps his aura, he can clearly feel the burning of his aura and the erosion of his spirit by the gray-black airflow.

No matter how powerful such a thing is, it is a waste if it can't be used, and he hasn't refined this sword yet, it's hard to imagine how much damage this gray-black air flow will do to himself after really refining.
