After entering the cave, Li Heiyu still looked blank, and he didn't recognize that this was the "home" where he had lived for a long time.

Zhao Lingtai took it directly to the spiritual vein.

When he got to the side, Li Heiyu suddenly stopped, and there was a change in his face, although it was subtle, but it couldn't hide Zhao Lingtai's eyes.

"Sure enough, there is a ...... play"

Zhao Lingtai was overjoyed in his heart and gave an order to let Li Heiyu absorb the aura and cultivate.

Li Heiyu acted as ordered, sat cross-legged on the edge of the spiritual vein, and began to run the exercises.

The exercises he practiced were quite mysterious, and once he performed them, among the seven orifices, there was a steady stream of black qi emitting out, and finally enveloping the entire body in it, which looked very strange.

Zhao Lingtai saw that he had practiced a few times, and he was already used to it, so he ignored it and went to the other side to meditate and vomit.

After a moment, he opened his eyes.

The aura of the spiritual veins was surging violently, and they were all rushing towards Li Heiyu, constantly being devoured by it. The current Li Heiyu seems to be a bottomless pit that can never be filled. It's so ferocious, it's not even as good as the puppy of the day.

About half an hour passed.

Roar!

In the black mist, a roar suddenly rang out, like a wounded beast roaring.

Zhao Lingtai's heart moved, stood up, and looked at it intently.

At this time, the black fog dispersed a little, and the scene inside could be seen, a figure was standing there, with an unusually tall figure, about a zhang, which was definitely not Li Heiyu's original size.

"Is this going berserk, is it going to mutate?"

Li Heiyu is an authentic demon cultivator, with a demon body, not necessarily a fish type - the fish form is most suitable for use in the water, but on the shore, it will most likely be half-human and half-demon. It not only improves combat power, but also loses its agility.

Jin Guang's transformation of Li Heiyu not only erased his memory and intelligence—it may have just been sealed, but also greatly reduced his strength, from an earth immortal to an early stage of human immortal.

Zhao Lingtai took him into the cave to see if Li Heiyu's strength could be restored and improved. You don't need to return to your peak state, as long as you get to the middle and late stages of the human immortals.

Zhao Lingtai was not worried that this big demon would get out of control because of this, there was a golden light.

After roaring for a while, Li Heiyu gradually calmed down, and most of the black mist around his body dissipated, revealing his true face, it was indeed a tall half-human and half-demon, but it was not the fish-headed human body that he had seen before, its head had the characteristics of a fish, and there were also human facial features, some scales on the cheeks, looking at it, there was a hideous meaning.

From the aura emanating from its body, Zhao Lingtai knew that its strength had greatly improved, at least a little higher.

This form is considered a half-demon?

It's just why, after absorbing a large amount of spiritual energy from this place on the edge of the spiritual veins of the cave, it will transform?

The spiritual aura produced by the spiritual veins in the cave is indeed different from the outside, not only is it much richer, but also contains other things......

It's just that Zhao Lingtai can't tell it, perhaps, this has something to do with the fact that the Dragon Cave Ancient Sect is a demon cultivation sect.

In the current world, although there are still demons, they have long lost the environment for the survival and growth of big demons. This principle is the same as the fact that it is difficult for a Terran monk to break through and become a human immortal. Demon cultivators need more cultivation resources, so it is more difficult to grow.

Not to mention the big demon, even the medium-level monster is rare to see, and there are only more little demons who have just opened their minds.

To a certain extent, Li Heiyu escaped from the sky and escaped to the world, and he has something in common with Zhao Lingtai, but his fate is different.

At this moment, Li Heiyu was in the form of a tyrannical aura, a pair of eyes, red rays burst out, looking at Zhao Lingtai, and said in a jerky voice: "You, it's you?"

Hearing this, Zhao Lingtai was stunned, how could the other party seem to have recovered some memories.

"Ah, my head hurts, who are you......"

Li Heiyu suddenly held his head with both hands and howled.

In an instant, Zhao Lingtai noticed that there was a yellow light flashing on Li Heiyu's chest and abdomen, and there were runes flowing in the light, but unfortunately it flashed too fast and couldn't see it clearly.

Zhao Lingtai was shocked and taken aback. Because the yellow light is very familiar: yes, it is the light of the heavens!

After the ascension was successful, Zhao Lingtai landed in a place called "Ascension to the Immortal Terrace", where there was a group of immortals in charge, and they were also quite stunned by Zhao Lingtai's ascension, because no one had ascended for a long time.

These immortals made Zhao Lingtai stand still, did a full body examination, and then planted the heavenly strip.

At the beginning, Zhao Lingtai didn't understand what Tiantiao was, and thought it was an identity token or something, and he didn't feel any discomfort at the time, until he was convicted later, and when he wanted to struggle, the other party only pointed to it, Tiantiao attacked, and the mana of his body was restrained, and it was difficult to perform, plus a binding immortal rope, the whole person was tied into a zongzi and reduced to a prisoner.

At this time, Zhao Lingtai understood the meaning of Tiantiao, but it was too late.

He remembered very well that the scene when Tiantiao had an attack was very similar to the yellow light on Li Heiyu's body just now. I dare not say that it is exactly the same, at least seven or eight percent are similar.

Li Heiyu also has a heavenly strip on his body?

No, since it borrowed the corpse to resurrect the soul, it is a shell, even if it has a heavenly rule, it is equivalent to liberation. Just like Zhao Lingtai was relegated to mortal dust, his original body has long ceased to exist. Tiantiao or something, naturally disappeared.

Then there is only one possibility, that is, the prohibition similar to the heavenly strip on Li Heiyu's body was planted when he was imprisoned by Jin Guang and transformed.

That golden light was able to exert such magical powers......

This made Zhao Lingtai even more surprised and curious about the origin of Jin Guang.

In a flash of yellow light, Li Heiyu hugged his head and shouted in pain, as if he had been disturbed by some strong interference. The original memories that were surging were suppressed again.

After a while, the tyrannical aura of his body slowly subsided, disappeared, and his size began to shrink, and finally, he reverted back to the appearance of a short man, wearing armor made of fish scales, bursting out with a faint cold light.

It's just that he looks sluggish, squatting on the ground, with a blank face. As if he didn't know what had just happened, he didn't know anything, he only knew that he was obedient to Zhao Lingtai.

Zhao Lingtai exhaled, and the change in the other party just now verified some conjectures in his heart. The spiritual veins in the cave mansion do have some special effects on Li Heiyu. But Li Heiyu has a ban in his body, which imprisons his nature and memory, and does not let him remember. And its strength is naturally restrained.

Jin Guang's move, on the one hand, may be to conceal some information, on the other hand, it may also be for Zhao Lingtai's sake, it is not easy to make an unruly demon a slave, so a special means must be applied.

Zhao Lingtai pondered for a moment, activated the Cave Mansion Formation, and teleported himself and Li Heiyu outside again.
