I state.
"Building a camper van yourself would require considerable training and effort. But for example, making something like a refrigerator wouldn't require much training."
"Refrigerator?"
Nina tilted her head.
I pointed.
"Do you see that box-like thing over there?"
"Yes."
"That's a refrigerator. ......Aristy, could you bring some juice from the refrigerator?"
"Certainly."
Aristy goes to the refrigerator and opens a can of grape juice.
She pours it into a glass and brings it over.
I say to Nina.
"Here, try drinking it."
"Y-Yes."
Nina touches the glass.
"Oh, it's cold......? The juice is cold?"
Nina drinks the juice.
"Delicious...... and yes, it's definitely cold!"
She says, as if deeply impressed.
I said.
"That refrigerator has the role of cooling things placed inside it. As you just experienced, it can make drinks like juice cold."
"I see. That's...... amazing. You're saying it can do the same thing as an ice magic user?"
"Yes. However, the refrigerator doesn't use any magic at all; it's a purely mechanical device. Creating something of this level would be easily achievable with enough effort."
"Is that so? With enough effort......"
Nina murmurs, as if contemplating.
Suddenly, she stood up.
With a serious face, Nina stated.
"I...... will work very hard. So please, guide and instruct me well!"
"Yes, of course. However, let's start in earnest after we finish our business in the royal capital."
"Yes!"
Night fell.
We decide to camp out—or rather, sleep in the vehicle.
While driving along a road through a forest, we park the camper van.
We prepare dinner.
Everyone eats hamburger steaks made by Aristy using modern scientific recipes.
Nina was so moved by the deliciousness that she shed tears.
Afterward, the topic turned to bathing.
After Aristy and I had taken our baths, when we suggested Nina use the bath as well, she was astounded.
"C-Can I really use the bath too!?"
"Of course. You may use up to two towels and bath towels. Ah, Aristy. Please teach her how to use the bath."
I had introduced "there is a bath" to Nina, but I hadn't explained how to use it.
Things like how to use the shower, or how to use the shampoo bottles, would likely be unfamiliar to someone from another world.
Aristy responds.
"Understood. Then Nina, to the bathroom."
"Y-Yes!"
Nina heads to the bath with Aristy's guidance.
And Nina took her bath.
20 minutes later.
Nina comes out of the bath.
"It was heaven......!"
She said with a melted-looking smile.
It seems the camper van's bath was very well-received.
