Peng Dong, an ordinary young man struggling to survive in the city, accidentally obtained a "memory exchange system" - as long as he completes specific tasks, he can exchange memory fragments with anyone and gain the other person's skills, knowledge and even life experiences. However, this system has a fatal flaw: every exchange will randomly leak a piece of one's own memory, and the system complains about it as "the most unreliable cheat".
Just when Peng Dong was exploring the rules of the system, he discovered that his childhood sweetheart Lin Yuwei was actually the victim of a "memory transplant" designed by his best friend Su Qing - Su Qing used some means to exchange Lin Yuwei's ten years of memory with him, taking away her relationship, career and life. What's even more frightening is that behind Su Qing stands a mysterious organization called the "Memory Palace" that masters memory technology. They are planning a "memory revolution" that will change human society.
Peng Dong was forced to get involved in this conspiracy. While helping Lin Yuwei regain his memory, he had to fight against the pursuit of the "Memory Hall". In the process, he continued to exchange memories with the system, growing from an ordinary programmer to an "all-rounder" with hundreds of professional skills. However, every exchange came at a cost - his memories became more and more fragmented, and he began to be unable to distinguish which ones were his real self.
When Peng Dong finally found a way to defeat the "Memory Hall", the system prompted that the control of the memory system in Su Qing's body actually came from a certain memory he had lost. And that memory seems to hide the ultimate truth about "memory exchange"...
