I Took My Sister to Survive in the Apocalypse

I was killed by my boyfriend and his mistress in the fourth year after the end of the world. I suddenly woke up, oh! It turns out that I have returned to the pre-apocalyptic period... Thinking of all the disasters during the apocalypse and me trying to survive in the wilderness, I feel so miserable that I have betrayed my family and friends, and I have been framed! This time I was reborn and I must get back what I lost. I sold my house, borrowed from all my relatives, and took out all the small loans, which totaled several million. I hoarded food, clothing, medicine, gasoline, and everything I needed for the end of the world. I opened a shelter in the barren mountains and mountains. I was ready for disaster, but... Why didn't disaster come in this world? It's all over. Isn't it going to cost me my life? The above content has nothing to do with my novel.
