In her previous life, she was a queen who was given to the palace as a pawn by her family. She mistakenly believed in the concubine of a snake and scorpion, and fell in love with Emperor Liangbo. In the end, she was betrayed by the two of them together, and her whole family was executed. She was dethroned and died miserably in the cold palace. Once reborn, she returned to the age of sixteen when she first entered the palace. This time, Su Wanqing put away all her innocence and transformed into a revengeful Shura. The highlight is that the heroine's revenge is not a simple slap in the face, but a step-by-step battle of wits and maneuvers based on the superb medical and poison skills. She can poison people invisibly, and she can also save people while talking and laughing, playing with people's hearts and pharmacology at the palm of her hand. Not only does she want to take revenge on the scumbag, but she also wants to overthrow this decadent imperial power, bring down all the enemies who killed her family one by one, and finally support the new king, listen to politics behind the curtain, and become a woman who stands on the top of power.
