In the giant city "Fukawa", memory is a commodity that can be extracted, traded, and consumed. The upper-class residents are addicted to buying other people's life experiences and seeking spiritual immortality; the people at the bottom are forced to sell their precious memories in exchange for the right to survive.
Ling Ye, a memory restorer who lives in the "Shenyuan District" at the bottom of the city, has long been accustomed to this twisted set of survival rules. He repaired the broken memory and repaired his numb heart. Until one day, he discovered a mysterious girl "Zero" in the abandoned memory data - her memory was like a perfect white paper, but it attracted the craziest pursuit of the city's ruler "Eternal Life Technology".
A desperate journey begins. From the sunless streets of Shenyuan, to the chaotic and disorderly mechanical relay layer, to the towering "Yongsheng Technology" headquarters. Ling Ye was forced to become an enemy of everything he despised, just to protect this girl who had nothing.
When the true identity of "Zero" - a living key capable of formatting the entire city's memory network - is revealed, Ling Ye finds himself standing at the crossroads of destruction and rebirth. What he faces is not only ruthless enemies and ruthless technology, but also the ultimate torture of human nature, reality and the meaning of existence.
In the abyss of memory, can he find his own answer?
