Shen Ling, number 0, a non-existent person.
He can self-destruct his memory for 72 hours, and he can also reconstruct the criminal logic of the entire city in 0.3 Seconds.
This time, he was ordered to track down the "Abyss" - a dark web coordinate that caused agents around the world to commit collective suicide.
The clues point to the last mission that he personally erased six years ago, and to a woman who should have died by his gun.
Every time he gets closer to the truth, a page of his memory is forcibly deleted by the system.
When all the evidence returned to zero, Shen Ling discovered:
The abyss is not an organization, but the back door he left behind.
The countdown begins, and he must find out whether "Betrayer Zero" is his enemy or his future self before he is completely forgotten.
