The modern city "Linhai City" is prosperous on the surface, but in fact it hides a secret world composed of "shadow whisperers" and "light hunters". Shadowspeakers can talk to shadows and borrow the power of shadows; light hunters make a living by capturing the shadows of shadowspeakers, thereby gaining immortality.
Lin Ye, 23 years old, works the night shift at a convenience store. He seems ordinary, but in fact he is the last "pure-blood shadow whisperer" but has not yet awakened his ability. In his shadow, there are sealed secrets that can subvert both worlds.
The light hunter organization "Xi Guang Hui" discovered Lin Ye's identity and launched a hunt for him; at the same time, Lin Ye gradually awakened his abilities while on the run, uncovering his origins with the "Shadow Realm" and the truth about his parents' disappearance.
