In Xinhai City, memories can be extracted, woven and traded. The top "Memory Weaver" Lin Mo woke up in a strange apartment and lost all his memories of the past five years. Only the broken smile of a woman was left in his mind. In order to find himself, he must return to his old ways and dive into the gray area of memory. His only clue was a silver pendant engraved with the word "Wan". As the investigation deepened, he discovered that the five years he had forgotten were not only related to a taboo technological experiment, but also involved a mysterious organization called the "Cocoon of Immortality." In the maze of memories intertwined between reality and fiction, Lin Mo not only has to fight against the people who erased his past, but also has to face the forgotten self.
