Memory Archaeologist

A global collective amnesia - the "Blank Decade" was completely erased from the minds of all mankind, and no one knows what happened in those ten years. Chi Yan is a scavenger in this forgotten city, specializing in salvaging discarded memory fragments from discarded memory chips and selling them to those who want to fill the void. Until one day, he received an anonymous package. There is only three seconds of footage inside: at the end of a corridor, a red painted door with the house number 073. He recognized the door.

The deeper the investigation, the closer to the truth - the three years he was forgotten by the world hid the core secrets about the "blank decade". And everyone who tried to find out 073 disappeared from the world within a week.
