[Doomsday + Rebirth + System + Fast-Paced + Self-Interest Above All] In 2050, excessive environmental destruction and pollution trigger a global catastrophe. Typhoons, torrential rain, freezing temperatures, and earthquakes follow one after another! Less than a tenth of the world's population remains. I am reborn before the disaster begins and awaken a Doomsday System. I stockpile billions' worth of supplies in advance, absorb every supernatural ability, and face the coming Doomsday head-on!
