After several hundred rounds of battle, both fighters bore injuries.
On Ren Tianhei's body, those black scales had already suffered large patches of damage, and even many of the spikes on his body had been torn off.
Xu Fan, too, had traces of blood at the corners of his mouth and his complexion was somewhat pale, appearing to not be in great condition, yet his expression remained as calm and detached as ever.
It was as if the incredibly intense battle was nothing more than a game to him.
For the moment, the outcome of the fight was still undecided.
However, the idea of retreat was gradually taking root in Ren Tianhei's heart.
He may seem to possess endless strength, but all this power stemmed from the Evil Spirits he had devoured.
After the fight just now, his internal energy had already been depleted by nearly half.
If the battle were to continue, he feared that even if he exhausted all his energy, it might still be hard to wear Xu Fan down to death.
