Su Xuan, a prison guard of the Azure Cloud Sect, possesses the Calamity-Fated Dao Body. Once he breaks through, he will attract a devastating heavenly tribulation, so he only wants to slack off and idle away his days. Yet various accidents lead the entire cultivation world to treat him as a hidden mighty expert. He tries every means to debunk the rumors, but the more he explains, the deeper the misunderstandings become. Opportunities arrive one after another, forcing him along a path of continuous leveling. Involuntarily drawn into the disputes between the righteous and demonic factions, Su Xuan confronts villains possessed by heavenly demons, faces ancient heavenly demons head-on, and uses his body as a vessel to seal the demonic source, completing the task of suppressing the world and sealing gods. Just when he thinks the great battle has ended and he can catch a breath, demons from beyond the heavens quietly peer at the mortal realm, and a new catastrophe has already descended. The slacker protagonist has no choice but to face his destiny once again.
