Three years ago, Yang Feng, who had suffered a blood feud, moved into the Su family incognito and became a "good-for-nothing son-in-law" who could be bullied by everyone. He suffered all the harsh insults from his mother-in-law and the cold ridicule of his wife's family. Only his wife Su Qingyue still had a trace of tenderness for him. No one knew that this young man who was cooking in the kitchen and being called around was actually a descendant of the Heavenly Medicine Sect that had been passed down for thousands of years. He was also the "Qianlong Commander" who had an army of millions and guarded the peace of the place.
When Su Qingyue was forced to marry as a bargaining chip by her family, when the Su family was in dire straits and on the verge of bankruptcy, when the former enemies showed their fangs and tried to eradicate her, Yang Feng finally stopped holding back. A golden needle can revive the dead, flesh and bones, shocking the medical world; with a single order, thousands of troops and thunder can sweep across the battlefield. Using his medical skills as a blade and power as a shield, he uncovered the truth about the destruction of his family and avenged the thirty-eight dead souls, while protecting his loved ones and trampling on the forces that once trampled on his dignity. From enduring humiliation and becoming a son-in-law to the supreme dragon, Yang Feng used his strength to write a legend that "medicine can save the world, and martial arts can stabilize the country".
