In the "Echoing City" where neon lights never go out, memories are commodities that can be edited, purchased and deleted. Lin Ye is the city's top "memory weaver". He can erase the painful past and implant a perfect golden age for the powerful. He was known for his scalpel-like precision and absolute emotional detachment, insulating himself from his clients' broken emotions. However, in a seemingly routine operation, a memory fragment that should have been completely erased unexpectedly resonated with his own forgotten past. A piece of memory that did not belong to the client, a blood-stained silver pendant, flashed through his mind, awakening the ghost that had been dormant for many years. Forced to embark on a dangerous journey to pursue the truth, Lin Ye discovered that the skills he relied on for survival and the cornerstone of peace in the entire city were built on a big lie. He must choose between false tranquility and painful truth, and this choice will not only determine his own identity, but may also ignite the entire city of echoes.
