Wang Lin, a history major college student, accidentally time-travels while visiting a museum bronze chicken artifact, becoming a rooster about to be cooked in the Great Qian imperial kitchen, and awakens the Invincible Evolution System. Risking his life, he knocks over poisoned food to save the emperor, is bestowed the title of First Merit Rooster, and receives a death-pardon token. Afterwards, he subdues wolfhounds and wild cats to form an animal intelligence squad, engages in sharp-tongued debates with treacherous officials in the imperial court, publicly exposes the state preceptor's demonic lies, and defeats the grassland warrior Baturu in three moves on the combat arena.
