The Charm of Soul Pets

Chu Mu was implanted with the White Nightmare against his will by Xia Guanghan, and taken to the Green Nightmare Island. There, under the Nightmare Palace's control, he was forced to fight in brutal battles alongside his soul pet Mo Xie in order to survive. Eventually, they became the youngest rulers of Prison Island and gained recognition from the princess. Chu Mu's newfound status granted him the title of Nightmare Master of Henghai.
