The story follows Xue Tianyi, formerly the Celestial Realm's greatest warrior. Framed by the Heavenly Emperor—who felt threatened by his immense achievements—he was stripped of his immortal status and banished to the mortal world, with a "Celestial-Suppressing Spike" driven into his body to permanently prevent him from cultivating. Before his punishment, he managed to bribe a celestial official to preserve a shred of his spiritual consciousness; after reincarnating, he lives in the city, acting as a student by day and transforming into a master thief by night.
