Frozen Apocalypse: I Hoarded Trillions of Supplies

[Doomsday + Rebirth + System + Ten Thousand Times Return + Steel Shelter + Absolute Self-interest] "Su Yue, you have so much food at home, what's wrong with sharing some with everyone? You can't be too selfish!" "Su Yue, I'm Manman. I'm so cold. Can you let me go in and take a hot bath?" In his previous life, the world entered the frozen apocalypse, and the temperature plummeted to a hundred degrees below zero. Su Yue was soft-hearted and distributed supplies to his neighbors. However, he was betrayed by the school belle and had his trachea cut open by his beastly neighbors, who used him as the last "reserve food." Three days before the extreme cold came back, Su Yue awakened the "10,000-fold return system"! As long as you spend money to stock up on goods, you can randomly get 10-10,000 times resources or cash back!

When the whole world went crazy over half a piece of moldy bread, and almost froze to death trying to pick up two sticks of dry firewood... Su Yue was lying in a constant-temperature fortress of 26°C, holding a 1982 Lafite in his left hand and shaking an ice-cold Coke in his right hand. Su Yue: "The heating seems to be too high. I'm a little sweaty. How about a bowl of iced mung bean soup to cool down the heat?" Aunt Zhang: "Su Yue, do you have a conscience? We are eating dirt outside, and you are making hot pot inside?" Su Yue sneered: Conscience? I don't have it, but I do have the automatic machine gun tower. How about you come over and get two shuttles? In this life, I am not a Holy Mother. Whoever dares to stretch out his claws, I will chop off his head!
