No Breaking, No Building

The story takes place after 1920...

Feng Yuchuan is a seemingly carefree young detective with no great ambitions, working in Shanghai's International Settlement.

Su Beimu is the young master of a wealthy family who has returned from France to inherit his family's estate.

They meet over a murder case and, through a series of twists and turns, become partners in solving crimes. The young master looks down on the detective's carelessness, while the detective can't stand the young master's stiffness. Fortunately, they have one thing in common: investigating cases.

They thought solving cases would be the perfect way to pass the time, but it turns out their meeting was destined to be anything but ordinary, long before they ever met. The detective is actually fiercely ambitious, while the young master is consumed by hatred. What paths will these two young men take in that extraordinary era?
