The transmigrator Chen Mo wakes up and finds himself in a school where everyone is an impostor. Relying on his "disguise skill", he masquerades as a senior impostor and graduates with a little red flower. He maneuvers between the Impostor Cleaning Bureau, the Utopia Bar of exotic beasts (the awake), and the Joy God community—one of the Seven Gods—serving as a triple agent and stirring up the three factions with intelligence. Amidst survival and leveling up, he gradually uncovers the astonishing secrets of the impostors, exotic beasts, the Seven Gods, and human history.
