Lin Chen, the heir to the hidden miracle doctor, was seriously injured in an accident and was rescued by Su Qing, the daughter of the Su family. In order to repay his kindness, he curbed his sharpness and became a door-to-door son-in-law who could be bullied by everyone for three years. He endured the humiliation and silently guarded Su Qing. His mother-in-law thought he was a weakling and insulted him by throwing leftovers at him in public; his sister-in-law mocked him as a poor loser and made things difficult for him in every possible way; even his father-in-law treated him coldly. Everyone thought that he would be a useless person who couldn't hold his head high all his life. Until Su Qing's high fever persisted and she was critically ill, her mother-in-law would rather call in a quack doctor than let him take action. Lin Chen, who couldn't bear it anymore, finally revealed his identity as a miracle doctor, used three silver needles to determine the cause, and cured Su Qing instantly. When those who used to despise him saw him being treated as a guest by top bosses and being hired by major hospitals, they realized that the trash in their eyes was actually a miracle doctor who even the top dignitaries treated with respect! From then on, Lin Chen fought back all the way, protecting his loved ones, repaying kindness, punishing evildoers, and started the peak life of his son-in-law as a miracle doctor!
