Cultivation world good-for-nothing Qing Yao was mistakenly blasted to ashes by someone else's heavenly tribulation, but howled her way into securing an Underworld official position on the Yellow Springs Road. After taking charge of the Book of Life and Death, she abused her "private power" to resurrect her Tianlei Sect master and elders, fiercely confronted destiny's chosen ones like Long Aotian, and even drove the Heavenly Dao crazy with the Book of Life and Death, forcing out a new Heavenly Dao cycle. Jiang Buyu chased her into the Underworld over a "ashes debt," shouldered karmic backlash for her, transforming from foes to colleagues, and eventually to a predestined match. An Underworld workplace drama with a strong bias toward protecting one's own and anti-trope refreshing vibes, where even the Heavenly Dao must admit defeat.
