The Ultimate Son-in-Law

Lin Yuan was so devoted to studying medicine that the Lin family patriarch drove him out of the capital. He spent the next three years as a live-in son-in-law. Three years later, the patriarch called him: the Lin family's next heir had developed a terminal illness, and Lin Yuan was the only person in the world who could save him… This earned Lin Yuan a fortune worth hundreds of millions, yet he was content to be an obscure husband by his beloved wife's side.
