Lin Yuan, an abandoned son of the Lin family, married into the Su family for three years in order to repay his foster father's favor and was regarded as a useless son-in-law. In fact, he possesses "celestial vision" (the ability to see through the essence of all things), and he has the inheritance of ghost doctors. For three years, he secretly investigated the truth behind his mother's "accidental" death, and found out that it involved the "Eight Families", the top forces in Jiangcheng.
When the Su family fell into bankruptcy crisis and his wife Su Wanqing was forced to remarry, Lin Yuan no longer tolerated it - but he did not overturn the table without thinking. Instead, every step of counterattack was accompanied by a price and layout, walking a tightrope between protecting his wife and tracing the truth.
