Su Yu is attacking himself, trying to use this powerful Fifth-Order force to plunge himself into absolute pain.
The Power of Pain can naturally cause enemies to experience intense pain, and it's also effective on oneself.
However, under normal circumstances, even the Pain Evil God wouldn't attack itself with the Power of Pain. Otherwise, the extreme pain would render it unable to maintain rationality, leading to madness.
It can abandon humanity but cannot abandon rationality. If it loses rationality, goes completely mad, and becomes a truly chaotic Chaotic Evil God, it equals death.
Yet now, Su Yu is doing what the previous Pain Evil God dared not do, directly using the strongest Power of Pain to attack himself!
"Ah!"
Su Yu screamed in pain again, nearly driving himself insane, but the feeling of being alive grew stronger and stronger.
The surrounding [Nihility] seemed to have been pushed back a bit.
