In "New Babylon", a giant city shrouded in eternal neon and continuous rain, emotions have long become a commodity that can be quantified, purchased and purged. Human beings access the "Garden of Eden" network through the "Heart Cocoon" system and experience perfectly customized virtual emotions, while real emotions are regarded as a "system vulnerability" that needs to be repaired.
Ling Xiu, a top "memory scavenger", his job is to dive into the deep sea of other people's minds and remove those painful, forbidden or inappropriate memory fragments. He has long been numb to this, like a precise surgeon, calmly cutting other people's souls, until he received an ordinary "aftercare" commission - to clear the last memory of a technology giant who committed suicide.
In the reverberation of the target's memory, Ling Xiu accidentally came across a piece of data that shouldn't exist: a warm, real tear. Behind this drop of eyelid, there is a primitive emotion called "sadness" that has never been encoded. It was like a virus that instantly infected Ling Xiu's dusty heart.
In order to find out the truth about this tear, Ling Xiu embarked on a dangerous path against the current. He discovered that there was a huge conspiracy behind the so-called "suicide", and that the "Garden of Eden" advertised as a paradise for mankind was based on countless "white noise people" who were deprived of their true emotions. He is hunted, betrayed, and forced to choose between false dreams and cruel reality. And why does that mysterious woman who always appears at critical moments have the same light as those tears hidden in her eyes?
