Rat Demon's Rise: The Fat Cat Who Saved My Immortality

At the foot of Spirit Mountain, Bai Jin'er, a white-furred rat demon, becomes a wanted fugitive of the Heavenly Court after a scandal involving the Lotus Lamp. On the run, she teams up with a gluttonous, sharp-tongued fat cat who secretly wields divine power. To escape their pursuers and lift the cat's curse, the two storm the Dragon Palace, blow up the Eight Trigrams Furnace, and wreak havoc at the Peach Banquet, setting off on a quest for the Seven Wonders Gems. But just as the seven treasures are about to be gathered, they realize they have fallen into the scheme of the immortal official Xuan Heng—and that Bai Jin'er herself is the seven-colored key meant to awaken the Taotie. The fat cat burns through a thousand years of his own essence to save her. Five hundred years later, Bai Jin'er, now the Demon King, meets once more a little orange cat who looks exactly like him.
