The immortals in the sky use the human world as a chess game and regularly "cleanse the world" to cleanse all living beings. The key piece in this game was actually a "trash" whose Dantian was destroyed. Lu Zhiyu was born with no pulse and was the most useless person in the capital. He just wants to be a wealthy and idle man, but he doesn't know that he hides in his body the "innate turbid body" that immortals fear most. Until that day, the emperor gave him a beggar smelling of alcohol as a teacher. The whole capital was laughing, no one knew that this beggar had killed Jiutian three hundred years ago. What's even more ironic is that his stunningly talented fiancée is desperately trying to get out of the engagement. She regards Lu Zhiyu as a stain in her life, but she doesn't know that she is just a body prepared by the immortal. The immortals looked down at the world and laughed at the ants' struggle. But they don't know - this time, a monster that can swallow the sky emerges from the ants.
