(The end of the world + rebirth? + Crazy hoarding + developing technology + infrastructure mania)
After being "reborn", Zhang Ye accidentally obtained an alien system and used alien technology to stock up like crazy in an effort to survive in the apocalypse.
A doomsday virus breaks out, and 90% of humans are infected by the virus and turn into zombies. The surviving humans are struggling to survive, but they don't know that a greater crisis is coming.
