Bai Lang has formed an expedition team that is said to be the most "unreliable" in history: the strict and poisonous Su Xiaoman, the muscular girl Tie Zhu, the yawning sleeping god, and the mysterious and poisonous leader Yue Li. In order to realize their dreams, they embarked on fantasy adventures across different worlds. From the doomsday wasteland to the magical forest to the mysterious future city, the team laughed together all the way, hurriedly solving the problems at hand, and growing up in the collision with each other. The three volumes of stories are independent of each other, but run through the ultimate mystery - Yue Li's true identity and the true secret of the Six Realms. In the end, with their clumsy courage and hilarious tacit understanding, they solved the crisis, saved themselves and their friendship, and their adventures finally became memories.
