Fu Bo and the others, of course, had heard of such a phenomenon before.
"My god, just a little more than a day, and Chu Yi has already refined the 'Nine Revolutions Technique' to its proper state."
"Elder Fu, according to what you're saying, does that mean Chu Yi has become steel? He's almost entering the stage of recreating his physical body, right?"
Chu Yi was unaware of what kind of changes had happened to him; he was actually in a lot of pain at that moment.
On one hand, he felt a kind of power throughout his body, constantly surging and colliding from within his internal organs...
In the midst of the collisions, Chu Yi could also hear a very harsh noise.
This sound was strange, like the hissing of a snake, but also a bit like scraping a knife against the outer skin of bamboo.
Anyway, ordinary people couldn't bear to hear this type of sound.
