Where the smoke ends, a heartbeat.

Shen Hanyuan was a feared arms dealer across the underworld — cold-blooded, paranoid, and calculating. Shen Tingxue was the result of a fleeting night of passion. At the age of five, after her birth mother died of illness, she was brought back to the Shen family. In this blood-soaked clan where the strong devoured the weak, she was the most neglected youngest daughter, born with a frail heart, kept alive by medication, and had long cultivated a temperament of silent endurance — never crying, never making a fuss. Shen Hanyuan originally saw her as nothing more than a disposable pawn, until the day he witnessed her coughing up blood that stained the training ground floor. The deathlike calm hidden within that slender figure made this ruthless man feel, for the first time, the fear of losing control.
