"Chu Mu, what's wrong with you? You don't look very comfortable?" Princess Jinrou noticed Chu Mu's expression and asked with concern.
"It's nothing." Chu Mu shook his head.
Chu Mu felt uncomfortable because of the turbulence in the soul contract.
Mo Ye continually released Netherworld powers during the battle, which had already exceeded the range Chu Mu's soul could endure. If Mo Ye were to unleash his power further, it could potentially affect the stability of the soul contract.
Mo Ye's mutant strength in Wanxiang City had indeed surpassed too much, reaching the Soul Controller Grade, where the rate of strength improvement had become much slower. Chu Mu's Soul Sense could barely keep up with its current mutation.
