Extremely cold and frozen apocalypse + rebirth + space + clone + system + power evolution + hoarding supplies + Gou + survival base + decisive killing
The last days are so dangerous, so of course we have to find a safe haven. The protagonist awakens space and clone powers.
The clone not only shares space with the main body, but can also go out to collect supplies in the apocalypse. Moreover, the skills learned can also be inherited to the main body, so that the protagonist's abilities are continuously enhanced.
The protagonist is betrayed by his girlfriend and is accidentally reborn three months before the end of the world. Rely on foresight, build a strong shelter in advance, and constantly stock up on supplies.
When the end of the world comes again, the global population will be reduced to ten, and human moral civilization will also be gone.
The fittest survive and the weak are eliminated, returning to the era of the weak and the strong.
