Li Ji'an's cultivation method defies mortality—whenever his vital energy depletes and his body withers, Rejuvenation restores him to an eight-year-old form. But with each rebirth comes bewilderment. His appearance stirs recognition in everyone he meets. "You're identical to my junior brother as a child—carved from the same mold," someone gasps. "Incredible," another whispers. "You're the exact image from my great-grandmother's painting." The questions intensify as shock sets in: "Could you be... Ancestor?" "Is this the Daoist Venerable's reincarnation?" "Could you be the Immortal King reborn?" Each cycle of Rejuvenation unravels new mysteries and attracts cultivators desperate to uncover his true identity.
