Extremely Cold Apocalypse: I Built a Doomsday Fortress

The end of the world is coming, and the world has entered an era of extreme cold. In his previous life, Chen Mo was tricked by his neighbor into opening the door because of his kindness, and died tragically in a snowstorm. After returning from rebirth, the first thing he did was sell his house, take out a loan, and stock up on supplies! Food, medicine, diesel, weapons, generators... Others still laughed at him for being crazy. But little does he know that in one month, the whole world will turn into a purgatory of ice and snow! When everyone was frozen to the point of death. Chen Mo has already taken refuge in the doomsday safe house he built with his own hands. It's minus seventy degrees outside. And he was eating hot pot in the house, watching the despair of all the sentient beings in the surveillance room.
