System: Absolutely Restricted Area

An unprecedented unknown virus swept across the entire blue planet. The day when the 1,000th isolation zone built to protect human survival was completed marked the beginning of the first year of the isolation era. It takes ten years for a suspect who is suspected of carrying dirt to enter the quarantine area to become a "clean person". After obtaining a "clean ID card", he can go to the absolutely safe area. There are still hundreds of millions of "dirty people" living in the "dirty land" outside the quarantine area. The story begins on the last day of the tenth year of the quarantine era...
