In Xinhai City, memories can be edited and deleted. Ling Zhou, the top memory weaver, can sneak into the deepest memories of others and repair wounds, but he can only not open the rusty lock in his own mind. He wanders in other people's past day after day, like a ghost without a hometown. Until he accepted a commission from a mysterious old man - to delete the last memory of his deceased wife. When Ling Zhou dived into the seemingly sad memories, he discovered a reflection that shouldn't exist and a familiar sound of silver bells. This sad memory turned out to be the only key to his own forgotten past, and behind the key was a conspiracy and truth that could subvert the entire world.
