On the day he was reborn and returned to the draft, An Lingrong was bound to the traditional Chinese medicine inheritance system. In this life, she saves people with a silver needle in her left hand, and kills her with a poisonous prescription in her right hand. Save those who deserve to be saved, and kill those who deserve to be killed. When the queen used cinnabar to harm the emperor's heir, she used the same method to repay him; when Concubine Hua used the pleasant fragrance to kill the heir, she let the poisonous fragrance come back to bite its owner. From abandoning her son in the cold palace to taking charge of the imperial hospital, she used medicine as a blade and poison as a front, vowing to make all those who wronged her and harmed her pay with their blood.
