Synopsis：Su Qinghe was destined to be the god of medicine, but his adoptive sister Su Qingwan repeatedly copied the prescriptions and falsely accused him by relying on the "god of medicine system", and finally died unjustly and tragically. After her rebirth, she worked step by step, writing prescriptions in public, using secret words, personally mixing "yin and yang water", and reversely using the system to expose the truth about Su Qingwan's plagiarism. At the palace meeting, she used magical medicine to cure the plague, and even exposed Su Qingwan as pretending to be the head of the Heavenly Medicine Sect, causing her to suffer the consequences. In the end, Su Qinghe cleared his grievances and returned to the Heavenly Medicine Sect, letting his partial family members pay with their blood.
