-120°C: My Safehouse Is Nice and Warm

【Apocalypse Rebirth + Ruthless + Endless Upgrades + Stockpiling + Revenge Without Mercy】 In my past life, the sun went dormant, the world froze over, and an apocalypse of minus 120 degrees descended! My kindhearted, self-righteous girlfriend opened the door and let in a pack of monsters. They stole all my supplies, broke both my legs, and threw me into the snow to freeze to death! Reborn, I returned to 72 hours before the apocalypse! My girlfriend once again urged me to be kind and share my supplies with the neighbors? “Share? Absolutely! You and your whole family can get out and share with them!” I slapped her and drove her and her family out of the house! Then I activated the 【Infinite Upgrade Safehouse System】! I spent every last penny, took out a million in loans, and frantically stockpiled supplies! 【Ding! Level 1 Safehouse: Bulletproof glass + geothermal heating!】 【Ding! Level 2 Safehouse: Automated defense machine guns + electrified perimeter fence!】 【Ding! Level 3 Safehouse: Self-sustaining farm + water purification!】 【Ding! Final Form: Planetary Mobile Fortress!】 The apocalypse arrived, turning the world into a living hell where everyone froze into ice sculptures. Meanwhile, I lounged in my warm, springlike safehouse, eating hot pot and drinking red wine. The neighbors who once mocked me were now kneeling outside my door, banging their heads until they bled, just to beg for a bowl of hot soup. And my ex-girlfriend, the one who had gotten me killed, was barely dressed and blue with cold, crying and begging me to open the door! “Open the door? Sure.” “If you want to come in, you’ll have to trade your life for it!” In this life, I believe in only one truth: in the apocalypse, kindness is the cruelest thing you can do to yourself!
