Doomsday Hoarding: Conquer the Country's Famous Goddess at the Beginning

(Zombie eating beast + climate catastrophe + rebirth to stock up on supplies + nanorobots + dark flow + exciting plot) Reborn half a year before the doomsday broke out, Lu Ming relied on his advanced knowledge to build a doomsday fortress, stockpile millions of tons of supplies, and enhance his original A-level talent (alloy blacksmith) to an S-level talent (nano-alloy blacksmith) through special methods of strengthening abilities. Create nano equipment at will. Nanorobots, as small as mosquitoes, can easily reach hundreds of trillions, overwhelming the world. The paper-thin nano-armor covers the body surface and is unbreakable. Nano flying blades as thin as a human hair form a protective net that can cut off thousands of troops.
