In Liuli City, where memories can be bought and sold and emotions can be customized, everyone is an island.
Lin Ye, a memory purifier with a ruined future, makes a living by processing other people's abandoned and dirty memories in the darkest corners of the city. He thought he would sink to the end in this cold ocean of data and neon, until he received a special commission - a black box imprisoning "living things".
This data ghost codenamed "Zero" not only dragged him into the pursuit of the military police of order and the vision of a giant enterprise that covered the sky with one hand, but also uncovered a terrifying conspiracy that could subvert the order of the entire city. The most fatal thing is that "Zero" is haunted by the shadow of the person he loves most in his life.
This time, he had nowhere to escape.
In order to protect this consciousness that should not exist, and to uncover the final truth of the hypocritical world, Lin Ye must reconnect with his dusty past and confront the man who once pushed him into the abyss. In this final showdown between humanity and technology, is he saving a fictional soul, or is he redeeming his already broken self?
When all memories turn into echoes, what is the proof of our existence?
