The rebirth of the medical master Ling Yun begins a counterattack. After Ling Yun was assassinated by the deputy sect leader Liu Changfeng, he was reborn as a street gangster of the same name, with a daughter Niannian and a wife Su Wanqing.
After rebirth, Ling Yun had to deal with the gambling debts and other troubles left by the original owner, protect the implicated mother and daughter Su Wanqing, and repair the relationship with them; at the same time, relying on the "Lingshu Book" inherited by the awakened Medical Dao Sect, he showed his superb medical skills to save people, such as treating Mr. Zhou and his daughter Niannian.
At the same time, he discovered that Liu Changfeng colluded with the Nether Palace to study the forbidden technique "Heart-Erosion Gu" to harm living people, and was also related to the death of Su Wanqing's mother. Ling Yun teamed up with Xuan Chen, an old member of the Medical Dao Sect, to collect evidence of Liu Changfeng's crimes. During many confrontations with Liu Changfeng and his gang members, Ling Yun gradually uncovered the truth and shouldered the heavy responsibility of revenge, protecting his family and revitalizing the Medical Dao Sect. The combined crescent moon jade pendant also heralded new secrets and challenges.
