In 2085, humans have realized "data-based storage of consciousness", and most people choose to back up their memories to the cloud system of "Trauson Technology", the world's largest technology company, to avoid memory loss caused by disease and accidents. The protagonist Li Lei is the "Consciousness Anchor Administrator" of Trauson Technology. His daily job is to repair the fragmented loopholes of cloud memory. His life seems to be stable, but he is always troubled by strange and recurring fragments - an abandoned laboratory on a rainy night, the vague words "Number 73", and a warning "Don't believe what you remember".
In an unexpected data crash, Li Lei discovered that his memory backup contained "artificial splicing traces". Even in the core database of "Chuosheng Technology", there were no original records from his childhood to the age of 22 at all. In order to find the true past, he was forced to leave the safe zone. While avoiding the company's tracking (Trauson Technology seemed to be covering up the secret of "Experimental Subject No. 73"), He joined forces with Xiaoya, a hacker from the resistance organization "Awake", to gradually uncover the dark truth behind "consciousness storage": the so-called "memory backup" was actually a trap used by Transson Technology to screen "high-quality consciousness containers", and Li Lei was the only surviving "Experimental Subject No. 73" - His body contained key data from the "Consciousness Immortality Project" half a century ago. When "remembered" are all lies, and "real" hides fatal dangers, Li Lei must spell out his own answer to survival between "preserving himself" and "stopping the consciousness enslavement plan".
