In Xinhai City, memories can be deleted just like data. Ling Su, the top "memory liquidator", erases his clients' most painful past with scalpel-like precision. He is calm, efficient, and never misses a beat, until he receives a special commission. The target was an old childhood acquaintance that he had long forgotten, and what needed to be cleared was actually a memory buried deep in his own mind. When the boundaries of his career collided violently with the dusty past, Ling Su was forced to embark on a dangerous road to trace his origins. In the sea of oblivion woven by technology, he must find the isolated island called "Truth", otherwise, he will be lost forever like those whose memories he has erased.
