The Divine Doctor Nanny Runs Wild in the Wealthy Family

Shen Xiyin, once a medical prodigy and elite forensic pathologist, goes undercover as a private caregiver in the powerful Bo family to investigate the mysterious death of her twin sister. The Bo family mansion is ruled by a strict hierarchy, like a modern imperial court. The various branches scheme against one another, making this so-called prestigious family more like an arena for beasts. Shen Xiyin's charge, the “young master” Bo Yehan, is rumored to be terminally ill and violent-tempered.

Using her exceptional medical skills and meticulous forensic reasoning, Shen Xiyin cracks one bizarre case after another amid lavish banquets and corporate power struggles, sending the “royal relatives” who use slow-acting poisons, staged accidents, and psychological manipulation to kill behind bars. She is both the meek, obedient caregiver and the knife-wielding avenger who strikes in the dead of night. As her investigation deepens, she discovers that Bo Yehan's “illness” is also part of a carefully plotted murder. The two go from testing each other to joining forces, ultimately bringing down this ravenous, predatory family.
