The Poison Queen Returns with a Space of Ten Thousand Poisons to Lay Waste to the Capital

Yan Jingyi, the legitimate daughter of the Chancellor's household, saw her fate overturned at the age of three. Her birth mother was falsely accused and murdered, and Yan Jingyi was abandoned in the hands of a poison doctor, turned into a human test subject subjected to poisonous Gu day and night. Tempered by despair, she unexpectedly developed a body immune to all poisons. After enduring years of hardship, she killed her enemies with her own hands and founded the assassin organization Butterfly Shadow Pavilion in the dark underworld, becoming a mysterious powerbroker who struck fear into the hearts of the powerful.

During her years in hiding, she unexpectedly crossed paths with Prince Rui, Song Wenjin, who bore a blood feud over his mother's murder. One was a blade in the underworld's darkness; the other, a formidable man who bided his time at court. Two equally strong souls met, moving from mutual suspicion to falling for each other, their deep affection growing amid the clash of blades. When the time was right, Yan Jingyi returned to the capital in force with the might of Butterfly Shadow Pavilion, turning her sword toward the Chancellor's household and swearing to avenge the blood debt owed to her and her mother. At the same time, she joined hands with Song Wenjin to unravel the plot and bring the mastermind behind his mother's murder to justice.

With their great vengeance achieved and the dust settled, Yan Jingyi and Song Wenjin cast off the glitz of court and returned to Butterfly Shadow Pavilion. From then on, the jianghu was their home, and they would roam freely hand in hand for the rest of their lives.
