A trace of blood sealed the fate of symbiosis between him and her.
When she was ten years old, Shen Qingyuan rescued a dying nine-tailed white fox from a snowstorm in the north, but was bitten by the nine-tailed white fox on his wrist, leaving a strange crescent blood mark. Evil lines formed in his heart veins secretly, and he became a "lonely evil star". In order to escape from the violent engagement, she mistakenly entered the fairy gate and was grabbed by the wrist by Ling Xuanzhou, the master of Lingxiao Pavilion - the cold-hearted nine-tailed fox emperor who had been rescued by her and transformed into a human form.
The bloodstains are painful, revealing the cruel truth: they are "born to sacrifice the demon pill, and they will live and die together". The evil spirit in her heart is the shackles of his old wounds, and his remaining demon elixir is the foundation of her existence. Forced marriages in court, slaying demons by immortals, framing of faults by imperial masters, spying by the queen mother... The conspiracy of black curse and soul-eating follows closely.
To protect her, he cut out her heart to extract blood, shattered the demon elixir himself, and willingly suffered the punishment of thunder; for him, she broke into the demon cave alone, lured evil spirits into demons, and stained her wedding dress with blood. From a runaway girl from the prime minister's palace to a half-demon emperor, from a cold-hearted fox emperor to a passionate husband. They used blood as a contract and sword as a contract, struggling to stay together in betrayal and desperate situations.
When the evil spirit and the demon elixir finally merged and tore apart the barriers between the three realms, what they created was not only a deep-seated love, but also a legendary epic in which humans and demons co-ruled and reversed destiny through symbiosis.
From being connected by bloodstains, to dying together in quilt; from beings and monsters taking different paths, to guarding mountains and rivers together.
