Gu Ci is a psychological counselor who makes a living by "cleaning up" other people's painful memories, but his true identity is a former top member of the mysterious organization "Shenjing". He can penetrate deep into the sea of consciousness and completely peel away the most unbearable memories.
He thought his retirement life would be about drinking tea, raising fish, and counting money, until he met female police officer Shen Ke.
The staff of an office building suffered collective amnesia and forgot all the words; the mirrors in a pedestrian street reflected non-existent figures; a park fell into eternal dusk, and time circulated here...
Behind each bizarre "urban ghost story", they all point to memories that have been "cleaned up". These memories that should have disappeared are eroding reality in strange ways.
And at the end of all the clues, the same number is engraved - 6634.
That was the only failure case in Gu Ci's career, an ultimate nightmare that was buried by his own hands but was about to emerge.
When forgetting is no longer the end, and memory becomes the most terrifying weapon, Gu Ci has to return to his old career.
"Hello, I'm Gu Ci. I'm a professional in dealing with the aftermath of all kinds of memory pollution, consciousness leakage, cognitive impairment and other messes. The price is negotiable. After all, my services are worth the world."
