As the drinks flowed, the need to use the restroom arose.
The toilet in this mansion was very special. It was a shower toilet.
Sure enough, voices were raised. A maid was stationed nearby to explain and ensure understanding.
It seemed to be well-received by the ladies. Well, the gentlemen didn't have as much use for it.
"Baron Cain, what is that! I want one of those!"
Suddenly grabbing Cain's shoulder and asking was the queen.
"Your Majesty, it's a shower toilet. It's a prototype I tried making by incorporating magic stones," Cain answered honestly. The only places where it was actually installed were this mansion and the Galm residence.
He had been told by Sara and Reine to install them, so he couldn't refuse.
When he installed them in the servants' toilets, the maids were overjoyed to the point of tears.
It must have been that good.
"Commercialize it immediately! That's a revolution. It's necessary!"
The queen was quite excited.
"What happened? Why are you so excited..."
The king joined in.
"It's nothing. Just go to the toilet. I asked for it to be installed in the royal palace immediately."
"Hmm... I don't quite understand, but I'll go and see."
The king was led to the toilet.
He returned a few minutes later, his face flushed and in a good mood.
"Cain! Install that in the royal palace tomorrow! Got it?!"
It was the exact same reaction.
Incidentally, Telesia and Silk had the same reaction. They said it with a slight blush, which was very cute.
"Understood. Although it's still a prototype, I have a few, so I'll install them as soon as possible."
"Truly, Cain always exceeds expectations."
With the installation confirmed, the king and queen were in high spirits.
The unveiling party ended, and the guests were given a pair of glasses as a souvenir.
All the guests who received them were delighted to hear about the contents.
These were the glasses they had used just a moment ago. Although he received several requests to buy them at the end, he had used all of them for the party, so he told them it would be fine after the royal family's offering.
The nobles who learned they could buy these glasses were very satisfied as they left.
The ladies were more interested in the toilet than the glasses. He told them he planned to sell them after more prototypes were completed. Selling them himself would be difficult, so he thought he would entrust it to a merchant guild.
After all the guests left and he took a breather,
"Father, thank you for everything. It went well."
He bowed to Galm.
"Don't worry about it. You're my son. This should have helped you gain favor with the other nobles. From now on, you'll have to do things on your own to some extent. Well, I'm not worried about Cain. I'm more worried that you might overdo it."
"I'll try to be more restrained."
Cain could only smile wryly. This party was not restrained, and he had incorporated elements from another world.
When he paid the people who helped him a small amount of silver as compensation, they were all delighted.
The maids worked for a month to earn one large silver coin. If they worked hard for a day and earned three days' worth of pay, they couldn't help but be happy.
He would need to continue to work hard in the future.
The next day after the party, he went to the royal palace to install the toilets.
Since there were few, he only installed them in the royal family's private spaces.
He received platinum coins as payment, even though the materials were just low-grade magic stones from the earth.
He was still using the platinum coins he received at his ennoblement, but they were increasing.
A few days after the toilet installation, he was called to the royal palace again.
With a wry smile, he got into his carriage and headed to the royal palace. Of course, he prepared ten sets of Venetian glass in case something happened.
He thought this would be enough.
He was led to the usual reception room and served delicious tea and pastries.
Thinking it might be another Reversi game, he was surprised when the king and the prime minister entered.
"Thank you for coming again. You did a good job last time. I enjoyed it. Still, you have quite a dark side, don't you? At five years old. You didn't tell Cordino I was there last time."
"No, no, it was my first party, so I didn't think that far. I didn't have any malicious intent..."
"Alright, if you have the glasses ready, I'll buy them."
"I have ten prepared today. Here they are."
He lined up ten glasses on the table.
The king took one and examined it.
"Hmm. They're beautifully made. Can anyone else make these?"
"I use magic to make them, so I can't say for sure. I even fainted once from magic exhaustion."
"Hmm. I see. Alright, come to the royal palace regularly. The price... one gold coin per glass, ten for a platinum coin?"
"Whaaaaat..."
He was shocked by the amount.
"What's wrong? If you're not satisfied, I'll give you two gold coins per glass."
The magic-made glasses, with free materials, became platinum coins.
"No. One gold coin is enough."
"Alright. I'll have it prepared immediately."
The king rang a bell he had at hand.
There was a knock, and a butler entered. The king spoke, and the butler bowed and left.
"I've told them to bring the payment. Now, to the main topic."
Another Reversi game?
"Cain, you're excellent at both swordsmanship and magic. The dragon you displayed in the entrance is proof. It takes considerable skill to hunt a dragon in such good condition."
The king looked at him sharply.
"Cain, you will regularly participate in the training of the Royal Guard and the Court Mages. There shouldn't be anything for you to do now. Understood?"
There was no room for refusal. Cain quickly gave up.
"...Yes, I understand..."
At five years old, he was to participate in the training of the Royal Guard and the Court Mages.
"In return, I'll grant you access to the Court Mages' library. Galm told me you've been reading magic books since you were little. There must be many you haven't seen yet."
This was very helpful. The magic books he had at home only went up to advanced level. The super-advanced fire spell 'Inferno' was a fluke because he knew the principle. He had no materials for other super-advanced spells.
"Thank you! I'm very happy."
"Only when it suits you, you act like a five-year-old. But the content you want to see isn't for a five-year-old."
Was it showing on his face?
"Your Majesty, I have a request. Is it alright?"
Cain asked.
"Sure, as long as it's not unreasonable."
"Since I'm still five, I can't register as an adventurer. I have some monsters I killed in the Gracia territory that I can't sell. Can the royal palace take the materials?"
"Of course, we'll take the monster materials. We don't need low-level ones like goblins. But for higher-level materials, there are many uses, whether for circulation or research."
The prime minister answered.
"Sure. That would be fine. It would benefit the royal family as well."
The king agreed.
"They're in my item box, so I can take them out anytime. Where should I put them?"
"The Royal Guard's barracks would be best. It should be easy to transport from there. I'll inform them."
The king and prime minister's permission was significant. The item box's capacity wasn't an issue, but he didn't want to keep them in there indefinitely.
"Alright. I want to play Reversi today..."
The king looked at the prime minister.
"It's not possible. We have a meeting today, and there's not much time."
The king looked disappointed.
"Then it can't be helped. Cain, another time."
The king got up and left the room.
"Go directly to the Royal Guard's barracks. I'll inform them immediately."
The prime minister said and followed the king.
Cain left the room and headed to the Royal Guard's barracks.
He explained his purpose at the entrance and entered. He saw a familiar face.
"Hey, it's been a while, Baron Cain, the hero."
It was Daim, the deputy commander of the Royal Guard.
