During the Jingtai period of the Yan Dynasty, in order to save his seriously ill mother, the down-and-out scholar Gu Yunzhou was forced to join the Chu Mansion, the Minister of War, and became a despised son-in-law. On the wedding night, he was seriously injured by an assassin and accidentally activated his father's relic "Jade Pendant of Life and Death". He inherited Guiguzi's medical skills and became a master of medicine.
From a son-in-law who was despised by his mother-in-law and ridiculed by his colleagues, to the envoy of the imperial hospital and the "miraculous doctor in the world", he brought the dead back to life with the Nine Palaces Rejuvenating Yang Needle, and used the Jade Pendant of Life and Death to judge life and death. Cure poison, defeat the imperial doctor, save the queen, and counterattack all the way. However, above the court, the powerful eunuch Wei Zhongxian controlled the government, and the three princes were eyeing him. The enemy Xiao Hanfeng who had used his hands was back, and the whereabouts of his father who was exiled to the frontier was even more unknown...
When the son-in-law wears the gold medal given by the emperor, and when the doctor is involved in the struggle for imperial power, Gu Yunzhou fights side by side with Chu Qingwan, who is disguised as a man, using the silver needle as the blade and the benevolence as the shield to fight his way through the turbulent capital. This is a battle between medical skills and power, and it is also a journey that rises from the mud to defy fate and change one's destiny - a son-in-law is not cheap, a doctor is kind-hearted, life and death are in his hands, and I own the world.
