In the 16th year of the Republic era, the merchant Yin family of Beiping, seeking self-preservation, drugged their illegitimate daughter Yin Zhaowan and sent her to the castle of a blood count hidden deep in the mountains, as a substitute for their legitimate eldest daughter. Waiting for her was the rumored three-hundred-year-old, cold and violent blood count, Qi Ye, and a mysterious bloody marriage contract written in the 42nd year of Emperor Kangxi's reign. In the castle full of heart-stopping moments, Zhaowan thought she only needed to play the role of an obedient "blood source container" to survive. However, with the contract's resonance, the strange movements of the black-gold ring, and the chilling words "You've finally returned," a shocking lie spanning three reincarnations was slowly unraveled. The contract that Qi Ye had guarded for three hundred years never mentioned a substitute—it was "Yin Zhaowan" herself. And the wedding document written in blood was not about "staying together for three lifetimes," but a curse of oblivion: "I am willing to trade the memories of every lifetime for you to live." As various forces waged war for the sealed Primordial power within the contract; as the Yin family, driven by greed, sold their own daughter to the underground black market; as Zhaowan finally peeled away the facade of "deep affection," she discovered that the man who professed to love her and endured three centuries of solitude for her was actually the "Primordial" who had set up this three-thousand-year trap. Prey and predator, deity and prisoner. At the moment of spacetime collapse, Zhaowan clenched the bloodstained cufflink in her hand, carrying a power sufficient to annihilate a deity, and leaped back to that rainy night three hundred years ago. This time, it was her turn to be the one on high—the "god."
