Acne festered in the Dayin Dynasty: Emperor Yongxi was obsessed with immortality and poisoned the Wandu Sect to seize the country's chalcedony. However, the seventh prince Xiao Jingheng suffered from "bone-eroding cold". The orphan Shen Zhiwei hid in the Taiyuan Hospital, practiced the forbidden technique of incense and poison with his extraordinary sense of smell, and vowed to avenge blood.
In the poisoning and murder case at the palace banquet, Xiao Jingheng, who was disgusted with fragrance, was addicted to her scent and abducted her as "medicine". She pretended to obey and used his power to track down clues to the family's destruction; he used her poisonous skills to detoxify and seize the heir, but he fell into a fatal attraction.
When the source of bone-eroding coldness points to the emperor, and when the identity of the poisonous beauty is exposed, the two face a duel with the collapse of trust. The appearance of the secret treasure of the previous dynasty caused natural disasters, the prince rebelled, the emperor went crazy, Shen Zhiwei activated the chalcedony at the cost of losing his sense of smell, and Xiao Jingheng cut off the dragon robe to put an end to the chaos.
At the beginning of the new dynasty, she scattered all the poison scriptures to build a medical valley to help the world, while he fought against all opinions and established the "Poison Technique Canon". Between the palace wall and the rivers and lakes, a wisp of medicinal fragrance connects the remaining warmth - it is atonement and rebirth.
