The scariest thing about a zombie crisis is that it occurs without any prior warning. However, if we know in advance and are fully prepared, things could be quite different… at least, that’s what I hope.

“The first important thing is stockpiling food. I want to buy a large amount of food that can last for at least a year, but I can leave that to Yae-nee. She can pick them out on her favorite online shop.”

“Leave it to meee. Not only will I choose food that can be stored for a long time, but I will also make sure they taste good.”

With her sister doing all her shopping online, she must have good judgment.

“Ah, but let’s make sure to discuss it before buying.”

“I got it!”

“We will have enough food to survive. Not only will we rely on online shopping, but I’m also planning to go out and do some shopping myself.”

“Oh, Jin-chan, Jin-chan!”

My sister suddenly started calling my name with shining eyes.

We are both old enough, so I wish she would stop using “-chan” when addressing me. But no matter how many times I tell her, she never listens. Even so, I can’t help but mention it.

“I told you to stop using honorifics already.”

“I won’t. Anyway, we need to replace our electrical appliances too! We won’t be able to get them repaired or replaced once they break down. We need to buy some spares. A gaming console and a shower toilet are essential, right?”

With eyes shining as if asking to be praised for making an incredible discovery.

“But before that, I have one question.”

“What is it?”

“Of course, if the world is in that kind of situation, not just electricity but also lifelines such as water and gas will stop, won’t they?”

“Ah.”

“I hadn’t thought that far ahead,” she said.

However, when it comes to our situation, the only problem we don’t have to worry about is water. We have a well and we also use filtered spring water for our tap water, so we don’t have to pay for water.

Living in the countryside is great.

“Does that mean we won’t be able to use our computers, game consoles, or TVs?!” she exclaimed, her eyes wide open as if they were about to pop out of her head.

“Of course, that’s right.”

“Are you telling your older sister to die!?”

You don’t have to be so desperate about it.

Well, for my sister who spends all her time playing games except for eating and sleeping, it’s a matter of life and death.

“It’s over. It’s over before it even began.”

She is feeling extremely down. It’s worse than when I told her about the zombie crisis.

Since leaving her like that is also troublesome, I’ll tell her the countermeasure I thought of in advance.

“Well, there’s a way to use electricity.”

“Huh, what?!”

She quickly recovered, lifting her upper body up from a prone position on the table.

“How about installing solar panels on the rooftop and utilizing solar power? There are also other methods that use natural resources like hydroelectric power.”

Our home is a two-story reinforced concrete structure, and from the outside, it looks like a gray square box.

The rooftop is easily accessible and quite spacious. Currently, it’s only being used to hang laundry or as a valuable place for my sister to sunbathe.

I’m dreaming about installing solar panels in some areas and using the rest for a home garden so we can be self-sufficient with fresh vegetables.

“Jin-chan, you’re a genius!”

“Anyone could have thought of that. Don’t hug me.”

My emotional sister leaned forward on the table again and clung to my neck. After shaking her off, I quickly searched online for companies that specialize in solar power generation.

It might be tight on time, but let’s find a company that can do it within our budget.

“Now I can be rest assured. I can’t imagine what would happen if we couldn’t use electricity. Ah, with this, we can play games and surf the internet without worrying.”

I thought that it wouldn’t matter if the world became like that, but I had another point that I couldn’t help but mention.

“Yae-nee, I think we can secure electricity, but… I think we won’t be able to connect to the internet”

“Huh?”

Once again, my sister’s face was filled with despair.
