Bloody Cold Wave, My Safe House Supplies Are Piled Up

In the last ten years, I have devoted my heart and soul to helping everyone around me. But in exchange, my brothers stabbed me in the back, my neighbors robbed me, my parents froze to death in the blizzard, and I myself breathed my last in hunger and cold. When I opened my eyes again, I went back to six months before the end of the world. Bloody acid rain, freezing cold wave, zombie siege... All tragedies have not happened yet. This time, I sold all my assets, crazily stocked up on supplies for ten years, and transformed my single-family house into a private fortress with iron walls. Block all the blood-sucking relatives and friends, lock the door, and isolate yourself from the world. Outside the door is purgatory on earth, with people dying of hunger everywhere; Inside the door, the heater is always on and there is plenty of food. Only my parents and I live peacefully. No matter who knocks on the door and howls in the wind and snow, I will not open a crack. This novel and its characters are purely fictitious.
