Yan Jin, a descendant of a family of modern Chinese medicine practitioners, unexpectedly transformed into the most inconspicuous concubine of the ancient Jing'an Marquis Mansion. The original owner was beautiful but frail and sickly. He was bullied by his aunt, plotted by his sisters, and was poisoned and disfigured at the beginning. However, Yan Jin was pregnant with the fragments of the ancestral "Qing Sang Sutra" and awakened an incredible ability - she could see the "aura" lingering on medicinal materials and poisons, using this to accurately identify the properties of medicines and crack strange poisons. She used poison to fight poison to repair her appearance, and used her medical skills to gain a foothold in the palace, but she did not want to inadvertently get involved in a shocking conspiracy: someone used ancient poison to secretly control important officials in the court, and even extended his poisonous hand to the emperor. In order to save himself and protect the people of Kyoto, Yan Jin teamed up with the regent, who appeared to be a playboy but was actually hiding a sharp edge to investigate the case. She has repeatedly solved strange situations with her extraordinary poison-curing skills, and has grown step by step from a weak girl in a deep boudoir to a "poison-healing master" who scares the powerful. However, when the truth gradually emerged, she discovered that the root of her time travel was a bad fate sealed by her own hands in her previous life... Faced with the choice between her loved one and the world, Yan Jin resolutely chose to use her medical skills to rewrite her destiny and walk out of the bloody storm of her own prosperous life.
