Apocalypse shelter - Swarg

A nobody who had barely done enough to survive in the apocalypse is killed and reborn a day before the apocalypse begins.
Unlike other stories he had read, the apocalypse he faced was truly a cruel one. With a much more simple system and little to no help from that, he has already witnessed the state in which the humans had once been reduced to.
Can he get up once again and face his nightmare?
If he can, does he have the ability to change the bleak future that awaits humans.


Warning : Not an overly fast evolving world like most apocalyptic novel. Everyone will have to fight with everything they have to progress and survive. The M.C. will have a higher growth rate but do not expect him to be overpowered.
