It took me about an hour to relax and finish my lunch. Ichiya was out in the mansion yard with Barletta after finishing cleaning up.

Before the two, several herbs previously planted are planted on the ground.

Next to it were also planted pots with lemongrass and peppermint, which Ichigo had bought for each seedling, and several herbal seeds.

Agricultural hauling vehicles that Ichiyoshi has boarded are also parked in the corner of the garden.

"It's getting pretty big, but it looks like it's growing slower than what's written in the book."

That's what I said, crouching in, Valletta staring at the herbs.

Together, Ichigo crouches in and observes herbs, but it sure doesn't look too big.

But it doesn't look like he's getting sick, and he's slightly flimsy, but the leaves look blue and healthy.

"What do you mean you're not even sick, but you're only growing slowly... Peppermint is getting a little bigger"

Compared to what is planted on the ground and other herbs that are potted, the peppermint planted in the pot appears to be growing slightly but quickly.

Since the peppermint in the bowl is given fertilizer, the only possible cause of the difference in the rate of growth is the presence or absence of fertilizer.

However, peppermint growth is still considerably slower than that of common seedlings.

"I think it's probably a nutritional problem, but I'm not sure how slow it is to grow even though I'm feeding fertilizer... and the herbs planted in pots mixed with fertilizer are also slow to grow,"

"Have you seen herbs every day and noticed anything?

"Did you notice...... hmm"

On a good question, Barletta puts her hand on her mouth and thinks.

"Nothing in particular... I try to give the water to the vertebra, and I pull out the weeds that grow around me when I realize... I didn't see anything different"

"Um, well... no, wait a minute"

"Oh, did you find out anything?

For how well he noticed something, Barletta turns her gaze with anticipation.

"I want you to tell me one thing, how big was the weed that grew in the bowl of peppermint?

"Is it weed? I was trying to pull it out as soon as it sprouted, so it wasn't that big. Big or about a centimeter."

"Is that what it's been like lately?

"Yeah, you're always the same"

To Barletta's words, Ichiyoshi thought with his arms together with his eyes on the potted peppermint.

That's how I kept my mouth shut for a few seconds, but I turned my face to Valletta again to see if my thoughts had come together.

"... for once, isn't this bowl no longer nutritious? With nutrition, weeds should get bigger all at once, so they're already completely depleted."

"What, but that's..."

Yiliang came up with the assumption that all of the fertilizer nutrition put in the bowl had been sucked away by weeds, and that the nutrition in the bowl had been completely depleted. There was also no thumping content.

He was Barletta, who was peeling her eyes in surprise, but when she immediately changed her mind, she took a look and opened her mouth.

"But that doesn't explain the rapid growth of vegetables in the field. Weeds should grow a lot every day, and it seems like before nutrition goes to the pompous planted leafy vegetables, they'll take it all to the weeds that started growing around them"

"That's true, but didn't everyone in the village pull it all out as soon as the weeds grew? Weed roots are still short when they get pulled right out, so I think the nutrients from fertilizers mixed deep inside will continue unattended. Since leafy vegetables continue to grow, it is believed that they have grown once and for all, taking in more nutrients as soon as they reach the remaining fertilizer."

To the best of their knowledge, the villagers went out to the fields every day, pulling by hand from one end the weeds that grew around the vegetables, or wiggling them with triangles.

I used to help when I was living in a village, so I know exactly how thoroughly the weeds were removed.

The drained weeds were left on dry ground, crunchy and withered under intense sunshine.

"So, but that would explain the slow growth of herbs planted from seeds, but it wouldn't explain the slow growth of peppermint seedlings. Even I drained the weeds every day, so the nutrition at the bottom of the bowl should remain."

"Yeah. Ever since Mr. Barletta came back to the village, right? But you only know the condition of the bowl while you were going to Isteria and you were away from the Mansion, the one in the village who took care of you."

"... ah"

To a good point, Barletta got a flashy look.

"Besides, the fact that I was watering my eyebrows every day meant that the soil was always damp, right? If the soil is damp, I think the nutrients at the bottom of the bowl will suck up with the water when the short-rooted weeds suck up the water. That's why it feels like the weeds have rooted up the slightest bit of nutrition left, and there's probably no more nutrition left in this bowl. The vegetables in the field were also fed water, but the frequency with which they were fed and the effects of the flames didn't always make the soil damp, and since the vegetables in the areas they were valued grew faster, they also beat the competition for nutrients with weeds."

"Ah... then, the plants of this world are... that, whatever they are, are doomed..."

"No, it's just a guess. It wasn't really decided..."

Barletta stares at the weeds growing on the property with her eyes as if to see something horrible.

If one good guess is correct, plants in this world will absorb nutrients within reach of their roots from one end and continue to grow indefinitely for as long as nutrition lasts.

Regardless, there are probably limits to growth depending on the type of plant, but as far as the village vegetables are concerned, it is not surprising to think that they will be even greater than they are now.

Also, as can be seen from the fact that the vegetables that have undergone abnormal growth could not be nourished even if they have grown up, they somehow remain of little nutritional value.

The nutrient intake from Japanese fertilizers is an anomalous condition in which all of it is used only to make it huge and the nutritional value of the vegetables themselves has not changed in any way.

Perhaps even if these plants withered and returned to the soil, it would not mean that all of those nutrients would return to the soil.

This repetition may have caused the soil of this world to be almost devoid of nutrition.

If so, I am also convinced that the very concept of fertilizer was not seen in this world.

The concept of fertilizer cannot arise because there is little nutrition from the source.

However, these are only a good guess.

Unless Japanese experts also investigate the plants of this world, the truth will be unclear.

"… so in the future I will try to isolate the peppermint bowls inside the house so that weed seeds do not enter. If Mr. Kazra's guess is correct, if we give him a new fertilizer, this peppermint should grow exactly as the book says."

"Yeah, I guess that's the only way to make sure."

When Ichiya nodded to Baretta's suggestion, she stood up and stretched her back.

"Well, then I'll go back to Japan again, won't I? I'll buy a lot of books, so stay tuned."

That's what I said and smiled. Fine, Barletta smiled when she stood up, too.

"Hehe, you're looking forward to it. Can you come home by dinner?

"Yeah, I'll be back by then. So, if possible, I'd like to eat Mr. Barletta's thick roasted eggs again..."

When Yi Liang said that as she seemed to illuminate, Valletta was blinking her eyes for a moment, but soon turned to a smile that seemed really happy.

"Yes! I'm waiting to make something extraordinarily delicious, so come back soon!

"Copy that. This has to come back in a hurry."

When Ichirano says so, he gets in the agricultural hauling car in the corner of the garden and starts the engine.

At the same time as I started the engine, a shitty explosion began to sound all around me.

To the sudden explosion, from the back of the mansion you can hear the roaring and feathers raised by surprise by the root-cutting birds in the fence.

From now on, it seems better not to park agricultural hauling vehicles on the premises of the mansion.

"Well, I'll be there… I'll park a little further from next"

When Ichirano said so, he drove an agricultural transport vehicle towards the cobblestone corridor leading to Japan.

Baretta dropped off her good back as she ran away and stopped her legs as she turned her heels back to enter the mansion.

Then, after his eyes turned to the weeds growing at his feet, he shifted his gaze to the herbs planted in the garden.

……

You have something to think about, Barletta stares at herbs.

Those eyes were only a little, wobbly with sadness.

Then an hour later.

Back in Japan, Ichirana had come to a large bookstore in the city.

There are hundreds of thousands of books arranged on shelves in the store, and there is a very wide range of genres available.

For people buying books in large quantities, even carts were available in the store.

Precisely for the best now, I quickly push the cart and walk around the store.

The first place Ichigo headed was in the corner of a history book, where mainly history books from European regions filled shelves.

Next to it on the left is also a shelf of Japanese history books, which also seems to deal with ethnic history and so on.

On the back side of Yi Liang is a platform loaded with lots of light novels flat, beside it is the "New issue of the month! 'A standing sign was placed.

The standing sign had a light novel promotional poster, illustrating a young man and a beautiful blonde girl who looked good to people, sitting on their backs together.

"Uh, I don't care what to buy when it comes to history books... I wonder if it's okay with BC Europe or something. Something from ancient Roman times."

I pull an ancient Roman relationship book out of the shelf that happens to be in my eyes, and I turn it all around.

The book contained easily understandable descriptions of the ancient Romans' first days of life, the techniques used, and what the tools used on a daily basis were.

"Well, this is how ancient Romans lived."

Keep reading a little, close the book and add to cart.

Even then, after streaming and reading several ancient Roman relations books, he added that they looked like they were in the cart.

Although the techniques and tools used in ancient Rome seem considerably more advanced than those used in the world over there, there are so many and varied books on ancient Roman relations.

Barletta is the only one who reads these books, so I paid no particular attention to such things as technological advancements.

Barletta's intellectual desire will also be satisfied to some extent, as there is probably something in common with the world over there about people's lives and clothing.

As far as military relations were concerned, it was decided to purchase a history of combat technology, with descriptions focusing on ancient Rome.

Historically important meetings and battles were described with diagrams in an easily understandable manner, including their course of battle and the background to the outbreak of battle.

Also, the ethnic history of Japan, which was on the adjacent shelf, added several copies to the cart with descriptions of areas close to my parents' homes in Saitama.

Yiliang then walked around the shelves of the specialty books and carted specialties on metal refining, agricultural relations, surgical surgery and nursing.

Some of the specialty books were in the cart two at a time, and I was going to use them myself if I needed them in Isteria.

I thought the specialty books alone lacked fun, and I also put magazines such as cooking magazines and space design magazines with lots of pictures in my hobby corner in my cart.

Previously, Barletta seemed to enjoy looking at a book with pictures called "How to Start a Popular Cafe," so I'm sure you'll like these magazines too.

"... you've got a rather chaotic lineup of what to say. How much would it all cost?"

The contents of the cart, where Pompom and various books were thrown in, were in a state of chaos with zero unity.

The existence of a book titled "How to Enjoy a Delicious Herbal Tea," which is placed on top of the history of combat technology, is indeed surreal.

Yiliang pushed the heavier cart to go to the cashier to complete the accounting.
