Kai was a cripple who couldn’t cultivate energy, but a tragic event which took his parent life and also create an opportunity for him to take another path to cultivate happened. The path he took was to cultivate the body and mind. His body will break all cultivation logic, and with his thought he will control all form of energy within heaven earth. With a thought he will become a devil, with a thought he will become a god with a thought he will become a mortal and with a thought he will become a universe. WITH MY BODY I WILL REIGN SUPREME. WITH MY THOUGHT I WILL BECOME THE KING OF ALL THE UNIVERSE PUREST ENERGY.
With a swift gesture, Kai assumes control over the potent energy of the seven sins that permeate Slaughter City's surroundings. This newfound power merges with the already immense energy that had been accumulating within his being, propelling him to the next level of his combat prowess in an instant.
The sky above the Slaughter City darkened, and a loud rumbling sound echoed through the City, awakening everybody from their thoughts and striking fear in their minds.
Kai directed his gaze to Serpent Demon, who was standing before him with an Intense frown on his face; as he could feel how terrifying Kai had become in just a second, he felt threatened by the Current Kai. Therefore he didn't wait for Kai to make any move before he rushed toward Kai with his spear; his speed was as fast as ever; however, in the current Kai's eyes, it was like a snail crawling forward.
