The Nine Heavens Lingxiao Immortal Emperor was ambushed by his archenemy, the Taiyan Immortal Emperor. His immortal body shattered, and his remnant soul fell into the mortal realm, possessing a red-crowned, golden-feathered rooster. As soon as he landed in the mortal world, he was attacked by a weasel, but fortunately rescued by a cute child. Bound by heavenly retribution, he cannot harm mortal beings. The once high-and-mighty Immortal Emperor is instead teased in turn by cats, dogs, and little piglets—a phoenix fallen to the plains is bullied by dogs! Season one nurtures the soul in the mortal realm, season two sneaks into the Yueling Immortal Sect to become an apprentice, season three fights against Taiyan's spies, and season four undergoes nirvana to make a comeback and return to the Nine Heavens to settle accounts with his enemies. The mortal animals that once played tricks on him also ascend to the immortal world together with him, staging a hilarious yet fiery comeback epic.
