Ye Chuhao returns from another world, hides his Immortal Emperor cultivation level, and returns to a martial arts campus, wanting only to be an ordinary class monitor in the country's lowest-ranked class. An archaeological live broadcast five thousand years later suddenly descends upon the firmament, successively unearthing the vice-monitor Dragon King, the labor commissioner God of War, and the classmates' hidden identities, leaving the mythological Class 9 watched by the entire world. Ye Chuhao eats melons on the side while covering for everyone, until the Three-Life Bronze Coffin is unearthed, and his true Immortal Emperor disguise can no longer be hidden.
