Upgrade Everything: Building an Empire in Nuclear Winter

Nuclear winter has turned Earth into a frozen wasteland where mutated beasts hunt and warlords rule through terror. Liu Wu awakens in this nightmare with nothing but a mysterious power—the ability to upgrade any item into something extraordinary. A rusty knife becomes a plasma blade. Scrap metal transforms into war machines. From a lone survivor scavenging ruins, he'll forge an industrial empire and command a mechanical army that will reshape the apocalypse itself.
