My name is Cao Ying, an ordinary woman who was involved in the "Doomsday Game" together with seven billion people around the world at the moment when civilization collapsed. When the sky was torn apart by bloody data streams, and the cold voice called "Judgment Day System" announced the end of the old world, I discovered that I was not left with nothing - I was reborn, and with vague memories of key events and resource points in the next three months, I returned to the hour before the doomsday. More importantly, on my personal panel, behind the [Attribute Points] column, there is not a number, but a symbol that shines with dark golden light: ∞. Unlimited points, this is my only and biggest BUG in this cruel survival game.
