With the air around him getting lighter, making it easier for him to breath, Azrael didn't even manage to get a second of respite as within just a split second, the comfort he just worked so hard to achieve all comes crumbling down, the power of petrification coming out of the Twisted Principality of Permanence increasing ever so slightly as if making sure that the power is keeping up with his improvements.

This makes it so that no matter how many times he had pushed himself through and endure the absurd, painful and uncomfortable effects of the petrification, he will always return to that state similar to when he just started the training, making it so that he can never get used to the principality's power.

Rather than frustration though, the young man instead felt extremely ecstatic as he withstands the mighty petrification power that is constantly sending him teetering on the precipice of death, the fact alone that he continues to persist despite the pain of having his body continuously turning into stone inside out, before he forcefully removes those parts all by himself and allowing him to keep living as his body recovers, before it starts becoming petrified again.

Through this torturous cycle of destruction and reconstruction, and then destruction once again, Azrael felt like he is already standing there for all eternity, all even despite the fact that he hardly reaches the thirty minutes mark now.

'That's really impressive…' with that said though, such time is already something enough to break records that the Twisted Principality knows of, his own, immensely powerful Petrification Domain that scares even the greatest geniuses of his era merely turning into a training grounds for Azrael.

Even if we were to factor the fact that he was far stronger back then when he fought those geniuses, that doesn't truly deny the fact that Azrael himself far outclasses those people purely in terms of talent and potentials, after all, in a battle of same strength against him, this Twisted Principality is capable of turning any of his enemy into a stone without any effort to his part.

And right now, not to mention of the same strength, the young man in front of him can barely match his might even with his greatest trump card in the table, this state also being limited to two minutes or else he will be in for a lot of suffering, and this very same young man is also the person that overcomes his petrification power without any hesitation, through gritted teeth and sheer will alone, of course, also mixed with the temporarily boosted combat power that nearly sent him to meet the creator himself.

'Tsk… this shit really hurts…' thinking to himself as he continues expunging out of his body the stone and mineral formation that is making his organs malfunction, Azrael in the meanwhile, thought to himself with gritted teeth feeling like he is about to die, the feeling of hanging in front of death with the only thing preventing you from meeting the harbinger being a weathered rope something that is probably the most accurate analogy for this training of his.

Despite the obvious, sharp yet also continuous pain hitting his body from all around though, the young man still holds on for dear life, with quite the excitement as well as he starts feeling like his body is getting more and more powerful as time goes by, as if he is about to break through another state of being.

Eventually, he starts feeling like the power of Petrification from Zhang Tian starts increasing once more, and yet from here on, it is even harder for him compared to the previous one, the fact alone that he felt like the level increased from totally alright and can handle to a might that would need him to start focusing even more.

What is extremely odd though is the fact that instead of focusing on defending himself against this power, he instead focuses on trying to figure out how he can use this attack from the principality to further improve the resilience of his body, this making him continue gritting his teeth as he forged on, the amount of petrified parts of his body he is continuing to fail to expunge and regenerate making him feel like he is far closer to death right now than ever before.

'Come on, hold on boy… I know you have it in you to gain that hidden stat…' Zhang Tian thought to himself with worry apparent on his voice as he looks towards the young man, the fact alone that the young man is still exuding such vigorous energy despite the petrification spreading all across his body a testament to the will still unyielding even in front of the powerful.

Meanwhile, continuing to endure the torture, Azrael already felt his knees turning solid making him unable to kneel even if he wants to, and despite wanting to free himself from such, sever his limbs then grow a new one, he is also incapable of doing so as both his arms are already turning into stone now as well.

'He's already way past the fifty percent strength of my petrification, and he still has that look on his else… really impressive' analyzing the resilience that he young man possess as he feels around, discovering the absurd amount of effort he is putting onto his petrification ability right now, and with Azrael withstanding its dangerous effects now without even using his Demonic Energy, even without knowing the body of the young man himself, the Twisted Principality is now pretty confident that at the very least, Azrael's Demonic Transformation should be extended for some few seconds now.

"In…increase the power even more…" snapping him out of his wondering, Zhang Tian was extremely shocked as he hears Azrael even able to struggle speaking despite nearly his entire body turning into rock now as well, making him ask himself, then the young man, just what makes him think that he can overcome the massive wall in front of him right now, that is the fact that only some few parts of his head has yet to succumb to Zhang Tian's petrification.
