Global Freeze: My Tower Defense with Infinite Options

[Doomsday survival + eternal winter + shelter + upgrade and construction + hegemony + material trading + growing protagonist + cruelty + no heroine] This is not a cool story. The protagonist will have a difficult time at the beginning, and the protagonist will not be merciful even if his basic humanity has not been lost. He will kill when he needs to. There will be no Madonna plot, no heroine. Everything is based on the interests of the protagonist. Global temperatures plummeted, freezing everything. Li Mo and eight billion humans were thrown into a cruel snowfield called "The Realm of Eternal Winter". Here, the "fire" is the only shelter, fuel is the bargaining chip for survival, and the direwolves and mysterious cold beasts wandering in the night prevent everyone from going out at night... At the beginning, he was naked and breaking ice branches with his bare hands. While others were still trembling for the first piece of wood, Li Mo activated the [Infinite Choice System]. When everyone is struggling on the line of survival, facing the extreme cold and despair of eternal winter and eternal night, the choice he faces is: the extreme high temperature of [Heart of the Furnace], the absolute realm of [Light of Shelter], Or... A [Carpentry Puppet] that frees both hands. "Brother Li Mo, where did you get so much wood?" "Brother Li Mo, how can your shelter be so warm? It's like being in a hotel." "Damn Li Mo! How dare you trick my ice core!" As a survivor and a black-hearted businessman, his only answer is: "Who told you that you don't have woodworking puppets? You have to cut the wood yourself..."
