In the future city "Xinhai" where memories can be extracted, traded and deleted, Lin Mo, the top memory diver, makes a living by sneaking into the sea of other people's memories. His real purpose is to find the "core memory" left behind by his sister Lin Xi, who mysteriously disappeared five years ago. An anonymous clue leads him to the forbidden place "The Forgotten Reef". He discovers that his sister's disappearance is not an accident, but a huge conspiracy involving immortality technology, the boundaries of consciousness and the bottom line of human nature. With the assistance of a mysterious woman named "Chen Xi", Lin Mo drove his "soul boat" that shuttled through the ruins of memory, sailing among the fragments of broken consciousness. Not only did he have to fight against the huge technological empire, but he also had to face the tampered past and his own twisted soul.
