A human and a demon fall in love and give birth to a son who is a half-demon. The half-demon has a special physique and is regarded by practitioners as a magical elixir of immortality.
Ning Yu is a half-demon who has been pregnant with a delicate fragrance since he was a child. He was entrusted by his mother on her deathbed. The tutor has not informed her of her true identity for 18 years, only saying that she is weak and warning her not to interact with outsiders.
When Ning Yu was ten years old, he accidentally rescued a woman in the corner of a side courtyard. The woman gave him a hosta that could suppress the strange fragrance.
The Taifu loved his son and could not bear to have him trapped in a small courtyard all his life, so he asked for permission to study in Hongwen Hall as a minor.
At that time, Pei Jingci, the son of the left general of the dynasty, accompanied the fourth prince Li Congzhen to the enemy country as a hostage. On the day when he returned to the dynasty after the five-year period, he first met Ning Yu, who had lost his way in the imperial garden for the first time.
The three of them follow each other like a shadow. The five years of companionship in the academy fleetingly pass by. The court is in turmoil, and the three of them are involved in the turmoil of seizing the heir apparent.
Li Congxu succeeded in seizing the title of legitimate heir, and on the day he was granted the title, Ning Yu's identity as a half-demon in the Jinluan Palace was exposed.
The emperor blocked the person's words and threw him into a prison.
Ning Yu drank poisoned wine and decided to die. When he woke up, he found himself in the general's mansion.
But the eyes of the two familiar people who had been together day and night before the bed were filled with the desire for immortality.
Fear spread from the soles of his feet. He wanted to raise his hand but saw a black cursed shackle appearing on his wrist.
Only then did Ning Yu know why his father tried so hard to prevent him from participating in the heir apparent.
No one in the world can refuse the temptation of immortality brought by the half-demon, let alone the emperor.
The never-before-seen flesh-cutting and blood-letting in the harem, the double mental and sexual torture, made Ning Yu, a pure and kind-hearted person, beg for death several times...
Concept: Everyone is trapped in the quagmire of desire, and no one can escape cleanly.
