Chen Qingyun traveled to the world of Red Mansions and became the concubine of a fifth-rank official family. She was an expert in toxicology and traditional Chinese medicine in her previous life. She is gentle and virtuous on the outside, but white and black on the inside.
In order to protect her family, she secretly assisted Shen Yanzhou, a scholar from a poor family, with poisonous medicine, and got involved in the power struggle in the court from the bottom of the capital. She made poison to kill people without being seen, used medicine to save people from dying, and helped her husband rise from the seventh rank of county magistrate to the cabinet minister.
There is no system, no golden fingers, just a step-by-step battle of wits and dormancy. Doting on your husband, torturing the scum, fighting wits, and farming-style upgrades.
