The next morning Jin decided to return to the village of Kaina.

"Thank you very much, Mr. Jin. Please keep up the good work."

"Thank you for the sword, Jin-san!"

Adamantite can be found in the mountains behind the village of Kaina. He used it to reinforce and strengthen the ordinary sword.

It was a mere iron sword, but it was transformed into a rare and famous sword.

Suddenly Jin had a thought that it might be the same for people.

He had been an ordinary person, but he had inherited the knowledge of Adriana Barbora Zetsi and had become a Magecraft Meister, a magical engineer.

The same is true for ordinary people.

That boy soldier Fred could change if he found something to be proud of. It might be knowledge or martial arts.

Then, we can discover buried talents and make them useful to the world. Jin strongly believes that education is the key.

It is just before noon when he arrives back at the village of Kaina. Golem horses are very useful.

"Now, we must not only work on the neighboring villages, but also on this one.

Jin muttered as soon as he arrived at Nido Castle.

"Jin-sama, have you thought of something?"

Bertsche asked. She is trying hard to gain knowledge that might be helpful for Reinhardt's estate management.

"I've been thinking a lot about what it means to make a good living," she said.

Jin answers Bertsche's question without reserve.

"Enriching our lives ......"

"After all, doesn't it mean that we have a lot of things?"

Saki, who was listening to the conversation on the side, expressed such an opinion.

"I don't think it's just about ...... things," said Erza.

Erza said. Jin moves to the conference room.

Before the discussion, lunch is served. Behle brought freshly baked bread. It was baked with yeast.

"Yes, this is delicious!

It tastes as good as anything I've had on modern Earth. No, maybe this bread is better because it is handmade with all natural ingredients and no unnecessary additives.

It tastes good even without butter or jam.

Food is not just about nutrition. A meal that does not bring pleasure to the palate is a meal without taste. Jin, who worked with children in an orphanage, knows this well.

Children are more honest than adults who know how to endure. A good meal brightens the face of those who eat it. It is a proof that the feelings of the people have also brightened up.

Jin, who has such an obsession, wants to seek for the richness of food.

"Food richness, huh?

When Jin suggested this at the meeting after lunch, Saki was the first to agree.

"I agree. People cannot live without food. Raising the quality of that food will lead to affluence.

"Yes. There is a saying in my world, "Eat enough and be civilized.

"Eat enough and know how to be civilized. ...... is it correct to say that only when you have enough to wear and to eat, you know how to be polite and decent?"

Bertsche's interpretation is correct. Jin nodded his head.

"I think it is not only a question of quantity, so that we can eat without any shortage, but also the taste that satisfies us at the same time."

"You mean that you can't be satisfied if you eat a lot of ...... bad food?"

Erza also understands the meaning of Jin's words.

"Yes. In other words, we need to increase the production of agricultural products as well as improve their quality, preservation and processing.

Everyone nodded. It seems that they understood what Jin meant.

"The in this village?　I would like to build one like that in Kaltz village. May I?

A snow chamber is effective in terms of preservation. Ice and snow can be created by magic.

Of course. ...... I'd like to spread the use of refrigerators, too."

"The price of magi crystals and magi stones will be a problem.

Saki is right. The price of magical crystals and stones is the bottleneck for ordinary people to get their hands on magical tools.

"......In the end, does it come down to an energy problem? ......"

As soon as Jin muttered this, Saki also had an idea.

"It would be great if we could make magi crystals."

Saki's casual remark caught Jin's attention.

"Saki, that's it!"

"What?"

"Can't we artificially create magi crystals?"

What?

Even for Saki, an alchemist, Jin's suggestion sounded preposterous.

Food or anything else, it cannot start without energy.

The energy problem is a pressing issue on the modern earth. Soaring gasoline and electricity prices are a painful expense for ordinary people.

"But this world has free magic element (ether) ......"

We can't make a perpetual machine, but we can make what can be called a <>. The combination of Aether Converter and ManaDriver that Reiko and her friends have in their body is it.

It is a clean energy source that converts free magical elements (ether) in the air into energy.

However, there are various problems in spreading it to the general public as it is. There is a concern that it may be used for military purposes, and if it is misused, it would be even more problematic.

"I wonder if it would be possible to use magi crystals like batteries. ......"

Jin was even thinking about such a thing.

"Hmmm, it would be revolutionary if we could do that. ......"

"Brother Jin, do you even know what magi crystals are in the first place?"

Erza has a point. There is no way we can make magi crystals if we don't understand what we are trying to make.

"I know that it is a mineral that contains magical element (mana).

"So that's where you start. But it sounds interesting!

"Jin-sama, if you could do that, it would be amazing if ...... the price is low enough!　It could change our lives!"

Bertsche also gave his approval.

"Okay, I'll start my research tomorrow."

"I'm looking forward to it!"

That was the end of that day's meeting, and Jin started to show off the new food.

"Well, what is it?

"Well, I'm looking forward to it.

Bertsch and Saki are also filled with anticipation.

"Hey, baby!

"Oh, here she is!"

Hannah's voice. Most of the children from the village of Kaina had arrived. Barbara and Eric are also there. Other villagers who were available also arrived, making a total of about forty people in the village.

They were gathered in the hall on the first floor.

"Jin-san, what are you going to feed us?"

Barbara asked, looking very excited.

"Oh, it's coming out now. ...... here."

Barrow, Behle, and the golem maids arrived with trays of something white.

"What?"

Everyone rolled their eyes when they saw what was handed out.

"Well, don't say anything, just try it first.

The food is served in a crystal bowl and scooped up with a silver spoon.

"It's cold!

It's sweet!

Delicious!

It was shaved ice. It was cold, sweet and sour, a true taste of summer.

It was made by freezing water with ice magic and shaving it with a shaved ice machine made with Erza's help.

If you eat too much, you will get a stomach ache. No more than two cups per person per day, but leave at least three hours between the first and second cups."

With the low price of 10 tol (about 100 yen) per cup, Jin started selling shaved ice at Nido Castle.

It was typical of Jin that he took proper precautions to prevent stomach upset.

The shaved ice became so popular that the idea and the shaved ice machine were sold to the Raglan Trading Company in the capital city of Alban for the price of 100,000 Tall.

In Alban, there was no limit of two bowls a day, so many people got sick to their stomachs from eating too much. .......
