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

I chose to give up using air conditioning and instead bought several large freezers and fans.

These would be used to freeze ice and store the ice cream that Cynthia loved.

By placing ice around the house and using the fans, it shouldn't get too hot inside.

If it did get unbearably hot, we could always open the fridge and let the cold air blow directly on us.

But that would require electricity. Although there weren't any power outages in the last life, I still bought a few generators just in case.

Since it was just me and Cynthia, I also bought some surveillance cameras and installed them outside the front door and on both sides so I could ensure the area around us was safe.

Next up was buying food.

Since it wasn't suitable to cook inside the bunker, I first bought plenty of instant noodles and biscuits. To make sure Cynthia could have something better to eat, I bit the bullet and bought a lot of convenience foods.

Looking at all these refrigerators, I thought for a moment and then bought various frozen foods as well. To avoid needing to use a stove, I bought two high-powered microwaves. They could not only be used to heat food but also to cook instant noodles.

Luckily, there were many near-expiry products available online, which were quite a bargain. Having gone through the previous life, I was certain that eating these so-called expired products wouldn't cause any problems.

I also bought some of Cynthia's favorite snacks, candies, and ice cream.

The upcoming sun would be hotter than red-hot iron, so I bought some supplements to ensure balanced nutrition.

Since both Cynthia and I were girls, I made sure to stock up on sanitary products and tissues.

Considering that Cynthia had fallen ill in her previous life, I bought some common medications as a precaution. However, I didn't buy much, since I hardly got sick last time and didn't want to waste money on that.
