In Xinhai City, memories can be extracted, repaired and traded. Lin Mo is a top "memory organizer". He can sneak into the depths of other people's broken consciousness and piece together the truth, but he can only face his own blocked past. One day, a mysterious woman named Su Wan came to the door with a severely contaminated "red-shift" memory fragment and asked him to retrieve a key memory about betrayal and death. When Lin Mo sneaked into the scarlet ruins of consciousness, he not only came across a conspiracy that could subvert the entire city, but he also discovered that the end of this memory was actually distantly related to his lost past. On the island of memory, he must sail through the turbulent sea of forgetfulness, or both will be swallowed by the tide of truth.
