Human civilization, which should have prospered in 2025, received a warning from the "Civilization Guarantee Agency" who claimed to be the last survivor of mankind in 2525 on January 1, 2025: Humanity has no future and hope, and the earth's civilization will end in 365 days. The unknown civilization is performing a cosmic space-time cleanup - they are uprooting human civilization from the long river of time by fabricating multiple key historical nodes. In 2525, the survivors successfully captured the time machine and used unknown technology to escape into the virtual quantum space before being obliterated by the force of time suppression. The "Civilization Security Agency" is calling on all countries in 2025 to form the last line of defense for mankind.
