Lu Xiaoxian, a waiter from a back alley, accidentally swallowed pills and became an immortal. Not only did he break into the heaven in despair, but he also inadvertently triggered a series of whirlpools of war between gods and demons. With the addition of strange teammates, the three realms embark on a hilarious adventure of teasing each other and cooperating with the alliance. From the internal strife in heaven and rebellion in the demon world, to the chaos in the demon world and the burning of soldiers in the human world, a "mythical palace battle" that concerns the common people has begun. The main lines of each volume are independent but wonderfully connected: in the first volume, "Into the Palace of Chaos", the protagonist soars to the heaven and encounters many adventures; in the second volume, "Laughing in the Three Realms", the origins of the three realms are explored, and power disputes break out; in the third volume, "The End of the Myth", everyone works together to end the troubled times, and the dust of their respective growth and belonging is settled. The book uses humorous language and tight rhythm to tell an absurd yet tender myth and legend.
