Shi Xing is the true son of Tian and the former Great God of the Ferocious Affiliation. At his introduction, he is under the curse of the Mark of Death placed by High Priest Xin Yue Kui, and serves as a major antagonist of the first arc.
After his defeat and temporary death at Zi Yu's hands, he resurrects with his memories restored, which had been corrupted by Shen Yen while he was cursed. Enraged, he now seeks his vengeance against the gods, forging a bond with the Immortal Phoenix to do so.
