Global Freeze: My Shelter Unlimited Upgrades

The Ice Age suddenly came, blizzards buried civilization, and the temperature fell below the limit. 90% Of humanity dies in the first ten days. Chen Mo was reborn and returned to the doomsday day, bound to the "Doomsday Shelter System". While others were struggling to survive in the ruins and fighting for a biscuit, Chen Mo was in his shelter, eating hot pot and looking at his former enemies trembling under the surveillance. "Upgraded exterior wall, defense level: can withstand extreme cold and snowstorms of minus 150 degrees Celsius." "Upgrade the greenhouse, unlock the 'accelerated growth' function, and fresh vegetables will ripen every three days." "Upgrade armed modules, deploy automatic sentry guns, warning: intruder detected." At first, people thought he was just a lucky hoarder. Later, when the terrifying polar beasts and the strange darkness of human nature swept over, they saw that the steel fortress standing in the wind and snow lit up with a scarlet light representing destruction. Chen Mo sat on the warm command chair, clicked the button, and issued a final announcement to the desperate Survivor Alliance outside the door: "Either surrender and work for me." "Or, become an ice sculpture."
