Frost Age: My Perfect Territory S1

'The Frost Age' has descended upon the real world. At 70 degrees below zero, I'm keeping my sister-in-law and myself warm with just a single bonfire... Orion Cole activates the one and only SSS-rank talent, 'Eternal Force.' He hoards food, smelts steel, builds a holy city, summons other races, and creates mechs. In this frozen apocalypse, he forges a god-tier territory, only to discover that the Ring of Frozen Silence is actually an alien prison?!
