In order to avenge the family's annihilation, Su Tan, an orphan from a family of poison magic, disguised herself as a mute woman and lurked around Xiao Jin, the only son of her parricide enemy, the crown prince of Dingbei, using poison magic as a blade. However, as they get along day and night, they gradually discover that there is another hidden story behind the murder that year, and Xiao Jin's paranoid possession and sincere confession of her have drawn her into a whirlpool of love and hate. When the truth came to light, it turned out to be a century-old feud between the two clans. Su Tan used his life to feed poison to break the stalemate, while Xiao Jin destroyed himself for love to protect each other. Finally, he used blood as a contract to cut off the shackles of fate with his broken body in the fishy atmosphere of the world and the court. Highlights: hard-core poisonous details, extreme emotional pull (love cannot be achieved → two-way redemption), identity reversal (the Avengers change the situation), and a strong sense of fate.
