After Miyauchi Hikage demonstrated the astonishing skill of making a small stone spin on the water's surface for several minutes with the power of the ripple before sinking, even though Renge was just a small child, she could realize that this was clearly not something a normal person could do.
Sensing his little sister's shocked gaze, Miyauchi Hikage didn't intend to keep her in suspense, but instead, in front of his sister, he demonstrated several simple uses of ripple energy.
Finally, he stood on the surface of the water and asked his cute little sister:
"Renge, do you want to learn this trick? If you want to learn, your big brother will teach you."
Renge's trust in her big brother was maxed out. After all, since she was little, she had never seen her brother lie to her even once.
Hearing that her big brother was willing to teach her, she nodded with such frequency that she almost left afterimages.
Miyauchi Hikage paused for a moment, then reminded Renge in a low voice, "But before you grow up... hmm, before you turn 10, you can't tell anyone, nor can you use it in front of others. Can you promise your brother, Renge?"
A child's world is very simple, and Renge was an obedient, good child.
She counted on her fingers. She was 6 now, and there were still 4 years until she turned 10.
Although the time was a bit long, since it was her brother's request, she would do as he said. Anyway, her brother would definitely not harm her.
Thinking this, she seriously held out her little finger to make a pinky promise with Miyauchi Hikage.
Seeing his sister's all-so-serious appearance, Miyauchi Hikage squatted down and gently extended his little finger to complete their promise.
"It might be a little uncomfortable at the beginning, but if you seriously feel the rhythm of your breathing, you'll get it quickly."
As he said this, Miyauchi Hikage placed his other hand on Renge's lower abdomen. A trace of ripple energy first gathered in her lungs and heart, and then was transmitted to all parts of her body with the flow of her blood.
This was the method Baron Zeppeli had used in the first part of the JoJo manga to make Jonathan quickly feel the ripple. First, all the air in the lungs is expelled, and then the diaphragm is adjusted, which can make a person maintain the rhythm of ripple breathing for a certain period of time.
This was the simplest way to guide a newcomer in practicing Hamon, and it was transmitted into his head along with the cultivation method for Hamon when he obtained it.
This morning, when he made the decision, he had also already tried it on his own body to ensure it wouldn't cause any harm.
The discomfort was also because the part about expelling all the air from the body would make one feel a little unaccustomed to it.
As Renge's little face turned slightly red from expelling the air, Miyauchi Hikage also felt that Renge's originally somewhat cold little hands had become much warmer due to the effect of the ripple energy.
Half a minute later, Renge, having expelled the air from her body and entered the rhythm of ripple breathing, officially began her practice of Hamon.
Miyauchi Hikage, on the other hand, continued to keep his hand on Renge's lower abdomen, feeling how much life energy had been activated within her body.
Of course, she couldn't be compared to a ripple genius like Jonathan, let alone a cheater like himself, but for an ordinary person, it was quite good.
Before he went to Tokyo for school, she should be able to get used to the rhythm of ripple breathing and complete the initial guidance of converting life energy into ripple energy.
As for more complex applications of the ripple, he could only teach her slowly during the holidays.
An entire afternoon passed in the teaching of Hamon.
Through this afternoon's teaching, Miyauchi Hikage roughly understood the time it took for a normal person to learn Hamon.
Without the guidance of other ripple users, being able to feel the life energy within a week and guide the ripple energy within a month should be considered a passing grade.
Miyauchi Hikage thought for a moment, "Considering my parents' ability to accept things, I'll first persuade them to try Hamon. As long as I guide them a little on the side, it should be enough for them to feel the life energy before I start school."
"Although it will be a little slower, compared to the benefits brought by successful cultivation, a month's time is nothing. And cultivating slowly is also less likely to attract others' attention."
"But just to be safe, I won't tell them the name 'ripple breathing'. I'll just tell them it's a health-preserving method I found in our old family warehouse."
The Miyauchi family, as the great landowners of Asahigaoka, had been settled here for hundreds of years. The warehouse of their old home was naturally piled with a large number of old objects.
Miyauchi Hikage had even previously seen legends about "oni" in some diaries left by his ancestors, which, looking at them, might even be from the setting of Demon Slayer.
So, disguising ripple breathing as a breathing method should not be a big problem.
After thinking it through, Miyauchi Hikage took Renge home. He prepared to first organize the cultivation method for Hamon in his diary before having a showdown with his parents.
And so, at seven or eight in the evening, when the holders of the diary opened it to check for updates, they saw an extra-long diary entry of several thousand words, even accompanied by some simple diagrams.
[The reward from the diary yesterday was Hamon. After using it for a day, I have now deeply understood its abilities.
In the spirit of sharing from the internet age, I have decided to share Hamon with you all to cultivate.
Of course, if you are not interested in preserving your youth and extending your life, then just pretend I didn't say anything.
Let's start from the most basic. Hamon is a breathing method derived from the sun. The principle is...
......
Under normal circumstances, you should all be able to complete the entry level within a month. After that, as long as you maintain the rhythm of your breathing, you can achieve the effects of preserving youth, beauty, and extending your life. If you encounter danger, it can also be used as a trump card.
Of course, ripple energy has many other combat-oriented uses, but I've written a bit too much in the diary today and don't want to write anymore. I'll share them with you when I'm in the mood some other time.]
A voluminous entry of several thousand words. Even though his physique was now far superior to that of an ordinary person, Miyauchi Hikage's hand was a little sore from writing.
"I've written so many words today. The diary's reward has to be a little more generous, right?"
Miyauchi Hikage's thoughts were quite optimistic, but it was a great pity that the best-combination pairing from the previous two days had probably used up all his dumb luck. Today's reward seemed a bit too plain and unadorned.
[You have drawn Volume 1 of "Saekano: How to Raise a Boring Girlfriend" (Author: Fumiaki Maruto).]
"???"
Miyauchi Hikage looked at the beautifully packaged light novel in front of him with a face full of question marks. The character on the cover was Eriri.
"I can even draw this kind of thing?"
Who knows what on earth is in the prize pool. Miyauchi Hikage retorted, then opened the book.
There were indeed no hidden mysteries inside; it was just an ordinary light novel.
The only problem was that the protagonists of the story all existed for real in this world, and in a few days, they might even become his classmates.
"So after school starts, should I find a chance to stuff this into the shoe locker of Kasumigaoka or Eriri to test them out?"
To test whether they had the diary in their hands.
The reason was simple. Miyauchi Hikage didn't know who could see his diary.
Although according to the general tropes of diary-viewing web novels, any female protagonist should be able to get a diary.
But what if this diary was also playing an anti-trope on him?
The possibility that he had been agonizing over nothing these past few days was not non-existent—
He had been searching for news about Hoshino Ai and Kamiki Hikaru these past few days, wanting to see if anything would happen to that scumbag, but unfortunately, there was no movement at all over there.
Now there might be many heroines who have seen the diary and are agonizing over who he is. He, naturally, would also be agonizing over who was reading his diary.
"But after all, the enemy is in the open and I am in the dark. The advantage is mine. After school starts, throwing this light novel out should be able to stir up quite a few waves."
Flipping through the light novel in front of him, Miyauchi Hikage began to calculate his probing plan for after school started.
