Sylvia is the maid and educator attached to Cain, and since she can also read, she taught me many things.

'Master Cain, I will read to you a picture book.

　Mentally, I was in high school, but I had no choice because I didn't know how to read.
　With memories of my previous life as a high school student, I took the humiliation of having a girl read me a picture book, but I took the letters seriously.
　He practiced himself, pointing to the letters and asking her how to read them, teaching her how to write.
　In this world, there is still no such thing as beautiful paper, and writing on parchment, fabric, and wooden boards has become the norm. Among them, this picture book was written on paper, and it was a high quality product.
　The author's mind and knowledge are still in high school. Moreover, he has a three-year-old brain, so if he studies, he can get into his head rapidly. By the time a month had passed, he had no more problems with letters.

'Mr. Cain. I'm sure he can read and write now. You're a genius for learning it perfectly at the age of three!　Master Rayne hasn't made it this far yet.

'Sylvia's done a great job. She was so good at teaching me that I figured it out pretty quickly.

　To get her to find the book she was really after, Cain cajoled Sylvia first.
　Sylvia was embarrassed by Cain's coaxing and put her hands on her cheeks.
　And this is where the real work begins.

'Speaking of which, Sylvia. Do you have any books on the history of this country or magic in this house?

They're both in the library of the house.

'You have both? I'd like to read that. Can you bring me a few copies of it?

All right, I'll bring it to you after lunch. I'll bring it to you after lunch, I don't think you'll be able to tell by reading so many difficult books, do you?

　In general, there was no way a three-year-old would want to read about magic and history. Sylvia nodded, wondering.
　It's been a month since she was reincarnated in this world. I can finally read a book on magic. Her spirits were rising.
　Since then, I'm in perfect physical condition, no problems, and I've received permission from Sarah, who is also my mother, to go free on the condition that I'm only in the garden of the mansion.

I can't wait to use my magic. Before that, though, I'm worried about whether I can use magic. ......

　After lunch, I was reading a story book in my room when Sylvia brought me a book on magic and history.

'Master Cain, I have brought you a history of the country and a simple book on magic.

Thank you, Sylvia. Sylvia.

''History and magic are both difficult. And we can't use status magic yet.

'It's okay, Sylvia. It's just knowledge for when I can use it eventually.

　I received the book from Sylvia and quickly looked at the title.

The History of the Esfort Kingdom.
"A Beginner's Guide to Magic

　The Kingdom of Esfort is the name of the country I live in now.
　It's been about three hundred years since the kingdom was established, and the current king is said to be the fifteenth generation.
　The first king was an adventurer who became a hero, became famous and founded a village, and from there built a city and a country in one generation. However, it's unclear where he was born.
　The first king's name was Yuya Terra Hirasawa Esfort.
　When I read the name, I was surprised.

'This is definitely Japanese, isn't it?

　The current king is Rex Terra Esfort.
　He was pulled out of Hirasawa some generations ago.
　The country has an aristocracy and is divided into royalty, grand dukes, dukes, marquises, frontier counts, counts, viscounts, barons, and knights. The grand duke is the brother of the king only, and is roughly divided into the higher nobility from the duke to the count, and the lower nobility from the viscount to the knight.
　Basically, the nobility is hereditary. However, the family of the head of the family is treated as quasi-knights, and the family of a quasi-knight is a commoner.
　In addition, honorary peerages and knighthoods are limited to the current generation, and the family members are treated as commoners. This is a policy to discourage the overpopulation of noble families. This is the policy to control the overpopulation of noble families, and it's inevitable since the state provides a salary to the noble head of the family, and the country would go bankrupt if there were too many heads of state.
　The Silford family has become a frontier county family, and is classified as a high nobility.
　The mansion where they live is so large that it can be called a small castle, and somehow Cain was aware of this.
　And finally, he put his hand to the magic book.

''Magic is fantasy after all, right?''

　I turned the book over and the first thing it said was one sentence.

'If you are baptized five years old and have a background in status, you should read it.'

　I turn the page, wondering if I won't be able to use magic until then.

'Feeling the magic in your body.'

　The magic sack in humans in this world seems to be located in the area of Tanden, near the navel.
　I've heard that it depends on the type of creature.
　I close my eyes and try to meditate.
　As I felt and explored inside my body, the Tanden area became hot.

I wonder if it's this one.

　When I became aware of the flow of magic power, I could see it slowly, but it was circulating all over my body.

''It's kind of like a blood vessel, isn't it?''

　As I was aware of this, I found myself moving at will.
　As I moved around in my body, I flipped through more pages.

'Gather your magic power at your fingertips and chant.'

'Hmm. Something like this.

　I concentrated on my fingertips as if I were gathering magic power, and chanted 'Fire!' with the image of a candle.
　I intended the image to be about five centimeters long, but a fifty-centimeter pillar of fire rose from my fingertips.

''Whoa!　You scared the shit out of me.

　The magic from his fingertips was diffused and put out the fire.

'I know I can use magic, but it's not safe to practice fire in the room. Let's just read a book on magic for today.

　What I found out while reading the book is that the four elements of fire, water, and climate are the basic magic attributes, and there are others such as darknessless light and sky. I'm not sure if it's a good idea, but I think it's a good idea.

I can't stand it, as a person with a knowledge of Japanese lantern books.

　Feeling the laziness of the magic reduction with the magic I just used, I turn to the magic book again.

'I wonder if it's in there somewhere about manipulating magic and extending the amount of magic power increase.

　I turn the page to find it.

'By using the magic circulation in the body on a daily basis, your magic manipulation will improve.'
The maximum amount of magic power in the body is increased by using up the magic power in the body and resting. However, the upper limit varies from person to person.

These are the two main things to start with. He's only three years old and has plenty of room to grow. From now on, we need to increase the amount of magic, and then we need to experiment.

　Grinning, I was satisfied to find what I wanted.

'Master Cain, it's time for dinner,'

　It was Sylvia's voice. She looked at the window and saw the light of sunset and before she knew it, it was dusk.
　She was too focused on her magic book, apparently.

'I'm coming!'

　I put the magic book away at my desk and leave the room.
　When I head to the dining room, Sarah and Rayne are already waiting for me.
　As we waited to take our seats, my father, Garum, came in at the end and took a seat.

'Then I ask you to give thanks to the seven gods of Marinford.

　After Garum was the first to sip his soup, they all began to eat as well.

''Cain. Sylvia tells me that you've been reading a lot lately. Do you enjoy books?
Yes, Father. Father. I'm not old enough to go out yet, so I'm enjoying learning more about the outside world now.
Cain is only three years old and he can already read and write perfectly.

　Sarah replied with a smile. I guess it's because she thinks her kid is smart, after all.
　That's because no matter how different the letters are, they actually have the concentration of a high school student, so it's pretty much all in their heads.

'I can't wait to get baptized and use my magic.

　In fact, it worked earlier.

I see. Maybe he'll become a court jester. Cain.

　My father, Garum, is also happy with his wine.

'I'm going to be a hell of a court wizard, too. I'll be Cain's senior, waiting for you!

　It seems that her older sister Rayne had magical qualities, and she wants to enroll in the school and study as soon as possible.
　In this world, students spend the time between the ages of 10 and 15 at the academy. Although there is a school in each of the territorial capitals, the highest level school is said to be the Esfort Royal Academy in the royal capital. After graduating from there, if you return to the territorial capital to look for a job, you will be welcomed with open arms.


　Then two years passed and it was time for the baptism of the five year old.

　For the first two years after he learned about magic, he studied, trained, and trained in magic incessantly.
　He called it a walk, but he also experimented with magic in hiding.
　As expected, if he used magic that was destructive to the environment, he would be found out, so he used his own weight, but he was releasing wind-attributed magic into the sky.
　As for self training, he had forgotten the word "self-weight".

'Yeah. I can be a wizard.

　With that in mind, Cain spent his days.


　Then the day of his baptism arrived.
