Shen Qingci, a descendant of a family of poisonous doctors, sneaked into the capital incognito in order to find out the truth about the family's destruction and the family's treasure "The Secret Scroll".
Using her superb medical skills as bait, she approached Xiao Heng, the frail and reclusive prince who was said to be poisoned.
In order to survive, he would not hesitate to seek the skin of a tiger; in order to seek revenge, she was willing to risk her own life.
The two tested each other in a heavy fog, walking step by step on the edge of life and death.
When the truth gradually emerged, they discovered that they were already caught in the same huge net.
Should we hold hands and solve the mystery together? Or will we all use up all the traps and become strangers in the end?
