Thirty days before the extreme cold disaster, I was reborn. In my past life, the cold wave locked down the city, cutting off water and food supplies, and I lost everything because I misplaced my trust in others. In this life, I sold my assets and emptied my inventory; food, coal, medicine, and fuel piled up the entire mountain, and I personally remodeled the mountain cabin into a safe fortress capable of withstanding minus sixty degrees. When heavy snow sealed the mountain and everyone fell into desperate straits, I took my family and a group of left-behind sisters, relying on a full warehouse of supplies and a set of hard skills to survive the longest winter and wait for spring to arrive.
