Apocalyptic Safe House: My Grandma and I's Survival Diary

I, Lin Wen, was reborn one month before the zombie outbreak. This time, I will never make the same mistake again. I suppressed the fear of zombies in my heart, hid it from everyone, used all my savings, crazily stocked up on goods, renovated houses, reinforced doors and windows, and built a doomsday safe house. Food, drinking water, medicine, weapons, thermal insulation materials... I moved everything I could think of back home. I welded the doors and windows, reinforced the walls, secretly stored storage, and renovated the water and electricity to turn the old house into a safe haven with iron walls. The end of the world is coming as expected. Outside the window are roaring zombies, chaotic crowds, and ruined cities. Inside the window, I am guarding my old grandma, sitting full of supplies, isolated from all dangers. I don't have a holy mother's heart, I don't provoke evil people, I don't blindly save people, my only obsession is to protect my grandma. Grandma didn't understand the cruelty of the last days, but she always believed in me and stayed with me. She used her gentleness to soothe the anger and nightmares caused by my rebirth. We cooked, heated, and counted the hours in the safe house, keeping an eye on everything outside the door. In a desperate world filled with corpses, we guarded a small world and depended on each other. The regrets of the past life will be made up for in this life; the sufferings of the past life will never be experienced again in this life. Even if hell comes outside, as long as grandma is by my side, this small house filled with supplies will be the pure land on earth that I try my best to protect and never fall.
