In the "New Arc City" where technology and decadence coexist, memory has become a commodity that can be extracted, traded or even deleted. The giant enterprise "Yongsheng Technology" dominates the joys and sorrows of the entire society with its monopolistic "Memory Crystal" technology.
Ling Su, a top "memory scavenger", works to accurately erase the painful past for clients. He was calm and numb, viewing his memory as a string of codes that could be rewritten, until a mysterious woman—Ye Ying—appeared in front of his door. She doesn't want to forget, she just wants to find a "ghost memory" that does not belong to her, but can subvert the entire city.
This small memory crystal was like a pebble thrown into stagnant water, causing deadly ripples. Ling Su discovered that this fragment of ghost memory was surprisingly consistent with the missing past in his mind. In order to pursue the truth, he was forced to join forces with Yeying and embarked on a desperate road.
Pursued by the elite executives of Eternal Technology, they travel through the light and darkness of New Arc City, from the neon-lit Sky Zone to the filthy Abyss Zone. Every step he took made Ling Su more suspicious of his identity. Who is he? Is it the cold scavenger, or the completely different person in the ghost's memory?
When the last veil of the truth is lifted, Ling Su will face a cruel choice: should he embrace the stable "reality" that has been tampered with, or find the "truth" that may completely destroy him? In a world where everyone can be reshaped, in what form will the true "self" exist?
