In Liulicheng, where technology and desire are intertwined, memories can be bought and sold, and identities can be customized. Ling Ye, as the chief memory tuner of the urban giant "Eternal Life Technology", has an enviable status and a perfect life. He can sneak into anyone's mind, mend broken memories, and erase painful pasts.
However, during a memory restoration of a deceased executive, he saw his deepest fear - in the fragments of memory, the murderer who pulled the trigger was actually himself.
Overnight, the perfect life collapsed. The past files have become a forbidden area, invisible eyes monitor his every move, and a codename "B-7" that he has never heard of follows him everywhere. In order to find the answer to "Who am I?", Ling Ye was forced to join forces with Han Ya, a mysterious woman from the dark underground, and embarked on a desperate road.
What they want to fight is the "immortal technology" that controls the lifeblood of the entire city, the ghost-like master behind the scenes, and the powerful and ruthless enemy who is chasing him - the woman who is inextricably linked to him.
When the fog of the truth was lifted layer by layer, Ling Ye discovered that he was not only a fake identity, but also the core of a grand and terrifying plan. Everything he holds dear is just a piece of code that has been implanted. This time, can he use his own choices to reshape his true self on the ruins of memory?
