Three thousand years ago, Elder Yuan colluded with the demons to trigger the Fallen Immortal Rebellion. Mo Yuan died fighting to protect the Three Realms, and his body fell into the Wangchuan River, leaving only half of the hosta and Ling Shuang (named Awan at the time). She practiced hard for hundreds of years to seal her heart and love, and became a cold-blooded lord in the name of Ling Shuang, but she never gave up waiting.
In the vision of Wangchuan, Xuanjia's shadow appears holding the other half of the hosta. His face is unfamiliar but has golden eyes with demonic characteristics. The peach blossom fragrance on his body and the fleeting pain in his eyes are all vaguely related to Mo Yuan. In order to explore the truth, Ling Shuang went deep into the old cases of the Celestial Clan and the secrets of the Demon Clan, only to discover that the war that year contained a shocking scam: Mo Yuan was not dead, but had his memory tampered with, his immortal bones sealed, and a half-demon body trapped in Wangchuan, becoming a pawn controlled by a certain force.
As the investigation deepens, Ling Shuang not only has to face the obstruction of the Celestial Clan and the covetousness of the Demon Clan, but also has to uncover the lies covered up by time - it turns out that Mo Yuan's "sacrifice" back then was to protect her from being implicated in a deeper conspiracy. Now, the price of awakening him may be to subvert the order of the three realms, or to personally cut off the bond between two people that spans life and death.
When half a hosta merges into one, does it reflect the lost lover or the truth stained with blood? Ling Shuang struggled on the edge of love and pain, faith and doubt, using frost as a blade and obsession as a lamp, in the fog of the world of immortals and demons, she opened a path to the past and the future, just to find the figure that had made her wait for three thousand years, even if he no longer recognized the old person, even if the road ahead was an abyss of eternal destruction.
