Three generations of men from the Xie family, a prominent family in the south of the Yangtze River, died suddenly and in bizarre circumstances, all of which were judged to be "emergency illnesses." Above the mourning hall, Xie Yun, the only surviving daughter, keenly discovered the strange red spots behind the ears of her father's body and the wax chips between the nails, openly questioning the so-called "family curse." When she uncovered the secret of the bronze incense burner in the face of everyone's obstruction, a centuries-old poisoning conspiracy disguised as "ancestral precepts" surfaced.
In order to find out the truth, Xie Yun teamed up with young prosecutor Gu Yunshen and followed the clues of the "Soul-Breaking Grass" into the Yunwu Mountains of southwest China, where they encountered the deadly pursuit of the mysterious organization "The Fragrance Keepers". On the verge of life and death, she discovers that the murderer is the most unexpected person around her. When the smoke of the soul-locking incense dissipated, a shocking secret related to the obsession with immortality was finally exposed - the lives of three generations of the Xie family were actually just sacrifices to open an ancient secret.
