(Female Channel + Fantasy Immortal Cultivation + Romance + Abuse) This book tells the story of Dugu Yunchen, a swordsman who is willing to become a whetstone in order to achieve the throne of Taoist monk Murong Suqing. From the first encounter in the mud of the mortal world with the life-and-death confrontation in the immortal world, he personally pushed his beloved into ninety-nine and eighty-one catastrophes, each of which contained eighty-one minor tribulations. When Murong Suqing finally became the Immortal Emperor, the "devil" who had forged an eighty-one-life feud with her quietly disappeared deep into the ruins. A million years later, when Murong Suqing, who had become the co-owner of all realms, was exploring the ruins of Taichu, she accidentally discovered the truth that had been erased by history - Dugu Yunchen used herself as a container to carry the filth of the world, and used eighty-one revenges to refine her godless bones. This work uses a unique perspective of "good and evil" to explore the nature of sacrifice and the weight of memory. When the truth is annihilated by time, the heaviest protection is often presented in the most cruel way. The ending in which the male protagonist disappears without a trace is also a metaphor for all the silent sacrifices forgotten by history.
