Ten years later, she is rescued by Mo Qingchen, head of the intelligence agents, given the name Li Wuyou, and begins a divided, "double" life.

By night, she is a secret agent who kills decisively, sword in hand, protecting the light.
Mo Qingchen is ten years older than she is. He gives her a new life, teaches her to control her power, and plants in her heart feelings she cannot put into words.
