Back to the Doomsday: Taking My Sister Away from Our Unfair Family

Although online loans were a trap, I didn't have any better options.

I applied to every loan platform I could find. Despite being young with no assets or income, the sheer number of platforms worked in my favor, and I managed to borrow over eight hundred thousand dollars.

I also took some gold jewelry that Audrey had hidden at home, scraping together a total of one million dollars.

With that money, my first step was to rent an abandoned bunker in the countryside. This bunker stayed warm in the winter and cool in the summer. In my previous life, many people had survived the apocalypse by taking shelter in such places.

This particular bunker was perfect for us.

It had a massive iron door weighing several hundred pounds. Although it had a lock, it wasn't much use. Once locked from the inside, no one outside could break in, not even with hundreds of people.

Even better, the bunker had its own underground water supply. The previous owner had installed a hand pump, and when I tried it, it still worked.

The real estate agent looked at me curiously and asked, "Why would you rent a bunker in the middle of nowhere?"

I had already come up with an excuse. "I'm planning to open an immersive escape room experience."

With a bit of pleading and persistence, I managed to pay just one month's rent upfront. The agent originally wanted a security deposit and advance payment, but since the bunker was hard to rent out, he reluctantly agreed to my terms.

After securing the location, I started stocking up on supplies.

The bunker wasn't small. Just by the feel of it, the temperature inside was about twenty degrees cooler than outside. I wasn't sure if it would change after the apocalypse brought extreme heat.

I had considered buying a few air conditioners, but then I realized the outdoor units would be vulnerable. If someone discovered we were hiding there and sabotaged the units, we could end up roasting to death inside.
