Lin Ye is a botanical gardener who can read the afterimages of crimes he has witnessed by touching the plants. The information is fragmented and needs to be combined with criminal investigation reasoning to piece together the truth. He hides from the police force and secretly cooperates with the criminal police captain Zhao Rui.
Serial murders occur frequently, and "black mage" flesh is left at the scene. Plants convey clues such as "the smell of disinfectant water" and "you destroyed my tree." Lin Ye had a splitting headache, nosebleeds, and his abilities were on the verge of collapse.
He traced the secrets of the old city's renovation and found that the murderers' targets were all participants in the tree felling. The plant memory points to the revenge doctor Chen Mo. In the end, at the abandoned research institute, Luluo gathered to guide the way, and Zhao Rui closed the network thunderously.
The case was solved, and Lin Ye became a "special assistance officer" of the police. A pot of strange green plants quietly conveyed a strange message - new shadows are spreading.
