Global Cataclysm: Building the Ultimate Shelter

A 4.5-kilometer-wide asteroid slammed into Yellowstone Volcano. A meteor shower and a dust cloud that blotted out the sky turned the surface into a living hell. Beneath the endless dark winter, humanity struggled to survive in underground bunkers. Chen Hao, reborn, acquired a strange furnace that seemed capable of smelting anything.

He obtained a fully automated intelligent AI assistance System. Chen Hao: ? The apocalypse is here. When are we going to get the shelter fixed? Today! (Apocalypse, no female lead, shelter-building and farming.)
