Gu Lin is a former detective who lives his life as a "disappearance case reserve" - he resigned from his job, can't stop drinking, and no one has called him in more than 300 days. Until one rainy night, the screen of his mobile phone sank into a deep well, dragging him into something called "the abyss": copies that cannibalize each other, and rules that are priced with lives.
There, a man who called himself Shen Yun blocked death for him time and time again. But when Gu Lin returned to reality alive and started to check this person, he found that Shen Yun had not found this person.
With no identity and no past, Lian Yuan's system cannot "erase" him because he is not in any data at all.
A person who is desperately trying to figure out "Why am I still alive" and a person who can't even answer "Who am I" have given each other their backs in one copy after another. They want to break in from
Come is not a certain building or a certain train, but the abyss itself - and the answer to that question: When the whole world refuses to leave a place for you, is there anyone willing to be your anchor?
Purpose: This book is about remembering and forgetting. Yuan is not a simple human-eating machine. Of course it is cruel - using rules to screen people and erasing those who can't answer "Do you still count?" But it also has another side: it will leave those who have no time to say goodbye forever in a morning where everyone is alive and well. It both erases and contains; it is the executioner, and it may be the only place in the world that still remembers certain people. It cannot tell good or evil, just like fate itself - ancient, chaotic, not stopping for anyone. Gu Lin and Shen Yun survived in such a force. They can't win it, and they can't break it. All they can do is remember each other in a world where people can be deleted at any time: I see you, I remember you, and I wait for you to come back. One sentence to highlight: The most important thing in this world is not life or death, but whether anyone remembers that you have been here and is waiting for you to come back. Whoever remembers it never really disappears.
