Chu Zheng had already flashed to the side, looking at the monster that the old man in the formation had turned into, his face was a little ugly.

Because the white aura in the Shura killing array did not hurt him much, although he avoided a lot, there were still many of them split on the monster's body, but what made him speechless was that those aura could only leave a very shallow wound on his body, and could not cause effective damage.

Chu Zheng felt very incredible, this person's madness state already made him feel amazing, he didn't expect that he could have such a strong defense after the madness, you know, even if the qi in the formation is a diamond, it can be cut, but as a result, the effect on this monster is not so obvious.

This is surprising, Chu Zheng's eyes showed curiosity, after killing the monster that the old man turned into, he must study it carefully.

Of course, Chu Zheng is still very confident in the lethality of the Shura killing array, as for the defense against the monster in front of him, there is no way to break through, it is mainly because he has no suitable materials in a hurry, all of them are replaced by stones, and the power of the formation is only less than one percent, if the special materials are used to evolve the killing array, Chu Zheng firmly believes that even if the defense of this monster is very strong, it will definitely not last for more than a round in the formation, and it will be strangled into powder.

At this time, the monster couldn't break out of the Shura killing array, and Chu Zheng didn't change the formation materials again, he also wanted to see how long this monster could last, and treated it as an experiment.

After about half a minute, the monster's momentum began to gradually weaken, no longer as violent as before, and the whole size began to slowly shrink, and the terrifying beast features on that face slowly dissipated, and began to return to the appearance of the old man.

Chu Zheng's eyes narrowed, he was carefully sensing the old man's state, hoping to find clues of his magical transformation from it.

The formation was still running, although it was all made of stones, but the power was also beginning to show at this moment, those qi stroked on the old man's body, and began to see the bones deeply, even if the old man was trying his best to dodge, but still left him with a lot of wounds that were close to fatal.

The old man's breath began to decline rapidly, and he couldn't live, Chu Zheng saw this situation, his hand swayed slightly, and the Shura killing array stopped running, leaving the old man with a breath of relief, and he was not dead yet.

"You...... You don't want to die!"

The old man seemed to have something in his throat, and his voice was not so clear, but he still stared at Chu Zheng deadly, and the hatred in his eyes could almost come out of sparks.

Chu Zheng slowly walked in front of his eyes, kicked his body with his foot, showed contempt on his face, and said lightly:

"The ending is obvious, it is you who will not die well, because you have done a lot of evil, and you are innocent of death!"

After speaking, the expression on his face changed again, because through the flame formed by the source of the Dao that was still burning in the old man's body, he clearly found that the organs in the old man's body had been burned out, even the heart had been burned into a scab, and the blood had stopped flowing, but the strange thing was that the old man's body still had a vitality full of evil energy, which maintained his divine consciousness from falling into darkness.

Chu Zheng fell into deep thought, feeling incredible, he simply turned over the old man lying on his stomach, and saw that there were several big holes in his chest and abdomen, and there was no blood flowing out of them, and the whole body was like a broken pocket leaking around, and there was no trace of blood flowing out, but this person's thinking was still there, and he was not completely dead.

Chu Zheng's eyes moved, and finally looked at the old man's head, he felt that the problem should be in this.

At this time, he will not be merciful, in order to find out the truth, he must use some means, and according to common sense, the old man must have died a long time ago, and the material in his current body is not his original life.

Boom!

Chu Zheng raised his hand and smashed his head, because the evil qi he sensed gradually began to converge here, indicating that the source was in the old man's mind.

Call!

A black gas came out, and the old man's head was still like a normal person, it was empty, there was no brain and blood at all, the whole thing was empty!

And that black smoke seemed to have spirituality, and after it came out of the old man's head, he directly rushed to Chu Zheng's eyebrows with a looming scream, wanting to borrow his body to regenerate.

Chu Zheng naturally wouldn't give it such a chance, snorted coldly, pinched a treasure bottle seal method with both hands, and directly imprisoned this black qi in the palm of his hand.

This black gas spread out a lot, and after it was really pinched into Chu Zheng's hand, it was only as big as a dragon's eye, and it was black and terrifying, revealing an evil aura, constantly trembling, trying to escape from Chu Zheng's grasp.

Chu Zheng no longer cares about the old man's body, because the real root has been caught in his hands, this is the root of the old man's ability to burst into change just now, but what kind of substance is this?

Chu Zheng was puzzled, looking at the black qi condensed into the size of a bead in his hand, looking for his previous memories in his mind, but he didn't match the number, and he couldn't tell what kind of substance or thaumaturgy it was.

He began to try to wrap this black qi with spiritual power, trying to see if he could break down a trace of it, trying to figure out its mechanism.

Just as his aura was covered with black qi, a terrible scream erupted from this black qi, as if it was made by a tortured soul, with endless fear and wail.

Chu Zheng's brows furrowed violently, this is ......!

Through the induction of aura, he gradually thought of a secret method that had been passed down in ancient times, the soul cultivation technique!

This kind of secret art was circulated for a period of time in ancient times, because it was too tragic and inhumane, and then it was not tolerated by the major decent people, and finally they couldn't bear it, and they attacked it in groups, and the sect that mastered this method disappeared in the long river of history, and this method never appeared again, and gradually people forgot about it.

At that time, Chu Zheng didn't know that he had been cursed and couldn't break through the cultivation, he flipped through some of the master's solitary books and former sage essays, and saw this past, and he didn't take it too seriously at that time, but he just felt that his predecessors really did everything they could to create countless roads in order to practice, but basically they didn't come to an end, some of them were broken and couldn't go at all, and some were criticized and difficult to continue.

The soul cultivation technique belonged to the latter, which disappeared in the crusade of the people, but Chu Zheng was still a little interested in the strange person who created this method, and wanted to know what his final outcome would be.

However, everything is buried in the endless years, and for that sect and that strange person, future generations are very jealous, and few records will be left, and it has long been impossible to study.
