After giving the female knight a facial for the second day in a row and making things extremely awkward, the village chief showed up.

He had prepared breakfast for us.

While the other villagers had already started working in the fields, I had just slapped Ilia’s cheek with my erect cock — and now I was being invited to eat. I felt incredibly guilty...

We went to the village chief’s house and received our meal.

Thanks to sage mode right after ejaculating, my intellect was heightened, allowing me to infer various things about this world from even the smallest details.

The rye porridge had a strong sour taste, like black bread boiled in water — exactly within my expectations. It was a bit harsh for a Japanese person used to white rice, but I figured this was standard for commoners in this world. I wanted to get used to it quickly.

On top of that, the village chief had slaughtered an entire pig and grilled the meat for us. I had seen some rugged, wild-boar-like pigs in the village, so I was a little nervous, but it tasted like normal pork. Even without a reincarnated Japanese person teaching them, they already had delicious pork here.

Judging from the village chief’s attitude and Ilia’s reaction, grilled pork was quite the luxury they had gone out of their way to provide. Ilia promised to send birds and wheat to the village later as thanks. In a city, you could sell the expensive cuts like the thigh meat and use the money to buy piglets to raise again, but in a rural village, that wasn’t possible.

After the meal, feeling awkward about being alone with Ilia, I took a short walk around the village before we departed. Though "walk around the village" only took a few minutes to see everything.

While strolling, I fell deep into thought.

If there’s a god in this world reading my mind and isn’t interested in isekai trivia, please skip ahead to the mark [★End of Masaharu’s Isekai Trivia].

This was what’s commonly called a "fishbone village" in the Middle Ages. As the name suggests, if you looked down from above, the roads formed the shape of a fish skeleton. There was a main road running through the center like a spine, with smaller paths branching off on both sides lined with huts. The population was probably around 20–30 people. Definitely under 100.

It was a village built using the existing terrain, which also meant it wasn’t newly cleared land. In other words, Ilia’s territory didn’t have enough farming tools or labor force (like oxen and horses) to clear forests on a large scale, nor were they cutting down forests en masse to build big cities.

The fact that they didn’t need to clear forests suggested that the population wasn’t exploding, or that this was a dangerous land where people died easily from disease or monsters. The orc horde we encountered nearby was further proof that this area was perilous.

Most of the land was probably covered in forest, roads were poorly maintained, and there was little interaction between the scattered villages. The region wasn’t very developed.

Even if I knew how to make mayonnaise or soap, I probably couldn’t prepare the necessary facilities or ingredients. There also wasn’t enough population or economic base to buy large quantities of goods. In other words, typical fantasy isekai worlds lack demand (a purchasing population), so even if you made novel products, you couldn’t run a successful business.

Even if you could make 100 yen profit per mayonnaise, with only a few tens of thousands of people in the entire economic zone, you’d never recover your equipment investment even if everyone bought regularly. To make a profit, you’d have to sell mayonnaise for thousands or tens of thousands of yen each.

In the real world, even companies that make mayonnaise struggle unless they raise prices despite all their management efforts. There’s no way an amateur isekai reincarnator could do it on a whim.

This is the same logic as why acrylic anime figures are ridiculously expensive despite seemingly cheap materials.

For example, let’s say you sell 10,000 acrylic figures.

To recoup the 2 million yen cost of a super-hard alloy mold, you need to add 200 yen per figure.

On top of that, the injection molding machine to melt the material costs 120 million yen. If used for 10 years, that’s 12 million yen per year, or 1 million yen per month. That means you need 24 yen in sales per second (assuming the factory runs 24 hours). Of course this is for full operation.

If the machine produces one figure every 20 seconds, that’s another 480 yen added to the price.

In total, just making an acrylic figure costs around 660 yen before labor and electricity. And the price varies greatly depending on size and sales volume.

In short, acrylic figures look cheap to make but end up expensive.

Why do I know all this?

Because my grandfather worked in a factory.

After retiring, he built a small shed in the garden and used an old, outdated injection molding machine he received as a retirement gift to do subcontracting work. I used to visit him and watch the molten plastic. I even tried sticking my dick into it while it was still soft thinking it would feel good, and burned myself. That’s why I know so much.

——Amazing, sage mode.

Knowledge is pouring out like a flood.

But the world I’m in seems a bit harsher than the average isekai, so knowledge cheating probably won’t work here.

How exactly am I supposed to use my knowledge of why acrylic figures are so expensive to achieve cheat-level success...? Acrylic figures became popular partly because they take up very little shelf space. They don’t spoil and are easy to transport.

Trading cards exploded in popularity for the same reason — small shelf space. Things that are easy to sell become popular.

But you can’t do the same with mayonnaise.

For soy sauce or miso, you need containers for transport and storage, but those also require specific conditions, so it’s not easy.

Spices were traded at the price of gold in medieval Europe, so maybe mayonnaise could sell even if expensive?

That argument is nonsense.

Spices were expensive because rich nobles used them as status symbols. It wasn’t because they tasted good. Showing off dishes loaded with spices to guests was a status symbol.

Some say spices were in demand because they preserved meat?

Also nonsense. Rich people didn’t preserve meat — they bought fresh meat every day. There was no need to spend a million yen worth of spices to preserve 100 yen worth of meat.

To sell mayonnaise at spice-level prices, it needs added value that appeals to noble status. Honestly, the modern Japanese-style containers would probably be more valuable than the mayonnaise itself. If I sold them as "fake ejaculation items" filled with white liquid, rich old nobles might buy them as a hobby. If I could spread bukkake culture among the nobility, the containers might end up more valuable than the product.

In conclusion, to succeed in business in this isekai, you can’t target commoners.

You need products that reach noble demand.

One-off items like Othello are no good. Developing subscription-style items that nobles will keep paying for is the key to rising up through commerce in this world.

All the complicated reasoning flooded my mind as if the me who was about to go crazy from consecutive ejaculations had been a lie. Men who show off too much trivia are disliked, so I should hold back in the future... 𝑓𝓇𝘦ℯ𝘸𝘦𝑏𝓃𝑜𝘷ℯ𝑙.𝑐𝑜𝓂

I calmed my mind by looking at the cleavage of a village girl bent over working in the fields. Her breasts were jiggling. Sun-tanned, healthy-looking tits are nice. I sometimes see posts on internet forums claiming that in medieval countryside villages, both East and West, people started having nonstop sex after age ten and fucked from morning till night in the corners of the village as if it were normal. I wonder if that’s true. Even though I looked around, I didn’t see any couples having sex.

With poor farming tools and labor, and low yield per area, maybe they were too busy with farm work to have time for sex?

Anyway, after finishing breakfast and resting, Ilia and I set off for her castle. Since I didn’t know the way, Ilia led, and I followed behind her. Because her ass was constantly on my mind, I was hard and it was hard to walk.

Back in Japan, I only got erect when watching erotic manga or videos, but since coming to this world I feel like I’m almost always hard. Ilia is completely naked under her shirt, and every time the wind blows, a faintly sweet scent drifts over... Girls themselves are just inherently erotic now. Just being near them gets me excited...
