The Memory Pawnshop: Selling Memories, Starting as a Servant

On the eve of the sect tournament, Chen Mo, a menial outer-sect disciple, has his spirit stone crushed by a senior disciple. After activating a rusty iron shard, he discovers he can copy any technique, but each time he uses it, a random memory is erased. To survive in the sect, he is forced to use his memories as bargaining chips, making deals with fellow disciples, elders, and even enemies: trading forgetfulness for cultivation techniques, resources, and a chance to live. But when he realizes that what he has forgotten isn't only pain, but also his mother's face, his brothers' names, and the promise he made to his first love, he must decide: keep trading memories for power, or find another way to live.
