Liu Ye, a young man from Black Ox Village, accidentally enters a secret-realm dungeon world filled with danger. While other participants strictly follow the rules, treading carefully at every step just to stay alive, he has an unconventional way of thinking. Instead of relying on schemes and strategies, he deals with the secret realm's inhabitants in a down-to-earth manner. What should have been a perilous series of trials turns into a hilarious farce, as all kinds of mysterious realm beings are driven to despair by his antics.
