Doomsday Reincarnation! I Am a Time Traveler

In 2012, a doomsday crisis occurred in the parallel world Blue Star. Zombies were rampant in the city, and monsters in the wilderness were flying. Humanity changed from the top of the food chain to the bottom of the food chain. When mankind was in despair, a reincarnation space appeared in the world, from which people could obtain unimaginable power. This was a paradise for the strong and a hell for the weak.
