The Demon King, reborn in Japan as a monk

"We are still in the stage of testing the frequency of the influence of mental energy on chakra, and the effects that different frequencies can have on chakra."

"Why not start by modifying the existing illusions directly?" Kurenai asked in surprise.

"First, I can't refine chakra, and the process is too slow without anyone's cooperation. Second, the existing genjutsu are all chakra genjutsu; while modification is simple, it might not be suitable for pure mental energy activation. Finally, I don't know many genjutsu. Apart from the two genjutsu recorded in the notes you gave me, teacher, I don't know any other genjutsu. Therefore, I want to wait until I've finished testing the mental frequency aspects before trying to modify the existing genjutsu and develop pure mental genjutsu suitable for me," Ishihara Akira explained.

"Then how do you want me to help you?" asked Kurenai Yuhi, who had never developed pure mental illusion magic.

"If it's not too much trouble, I hope Teacher Hong can teach me more techniques for casting illusions—for example, finger gestures, light transformations, sound illusions, and some knowledge about creating illusions. Would that be alright?" Ishihara Sho thought for a moment and asked with some hesitation.

Of course, if possible, he would also like to learn more about orthodox chakra-based genjutsu as a reference to develop his own genjutsu.

However, just like ninjutsu, which has strict requirements for teaching and dissemination, the teaching of genjutsu also needs to be treated with caution. Therefore, Ishihara Sho was not in a position to make this request rashly before establishing a proper relationship with the subject.

Moreover, simple illusions are indeed not as suitable for me as these techniques.

So it's not too late to learn from Kurenai Yuhi when the opportunity arises later.

“Okay.” Kurenai thought for a moment and did not refuse. She patiently instructed Ishihara on the techniques of releasing illusions, especially how chakra affects the target to create illusions. She explained it in great detail. Then came the combat techniques of illusions, which is what Ishihara had mentioned before: moving a finger to make the target fall for the spell, using changes in light to make the target fall for the spell, and the release of sound-based illusions!

This place is filled with the utilization of the battlefield environment and the psychological games between people. It may seem that it is of no use to Ishihara Sho, who will definitely not go to the battlefield, but it is the essence of the entire illusion release.

You could say that if you master these techniques, even if you don't use illusions, you could easily become a magician just by using them to fool ordinary people!

……

With one side eager to learn and the other eager to teach, time flew by and it was around 10 p.m.

"Alright, that's enough for today. You should also organize what you've learned today. If you have any questions, we can discuss them again tomorrow." Kurenai glanced at the clock on the wall and advised Ishihara Akira in front of her.

"Okay. Thank you for your help, Professor Hong." Ishihara Akira stood up and said politely.

"It's nothing. I happen to be quite interested in the pure mental illusion magic you mentioned. Who knows, my future path might lie in this very field. So, you should work hard!" Hong smiled.

"Okay, Teacher Hong, I will develop a pure mental illusion as soon as possible so that you can verify it."

"Then I'll wait and see."

Afterwards, Ishihara Akira left Kurenai's house and watched her return to her apartment.

"Ishihara, I should go back too." At this moment, Tenten also came to the entrance and said.

“I’ll take you,” Ishihara Akira said.

"No need," Tian Tian waved her hand.

"Don't worry, I didn't come specifically for you. I just happened to be going out to buy some late-night snacks and brought them to you on the way," Ishihara Akira said with a light laugh.

"No wonder no girl has liked you in six years. With your inability to speak properly, it's no wonder no girl would like you," Tian Tian complained.

“But what about you?” Ishihara Akira said with a smile.

"I don't like you," Tian Tian said, blushing.

They left the house together and headed towards Tian Tian's house.

"Then I'm going in." At the door of Tenten's house, Tenten stood there waving at Ishihara Sho.

"Go inside quickly."

"See you tomorrow."

After saying that, Tian Tian turned and ran into the courtyard, disappearing from Ishihara Sho's sight.

Naturally, Ishihara Akira didn't linger at Tenten's place. He turned and headed towards the shopping street...

Chapter 63 Invisible

Shortly after, Ishihara Akira returned carrying a plastic bag.

"Ta-da!"

"Crack."

"You are..." the man standing inside the door of the Kurenai family's house asked with a puzzled look.

"You must be Jonin Asuma? Hello, I'm Kurenai's neighbor, my name is Ishihara Sho. This is takoyaki I bought for Kurenai on my way back. Please give it to her for me, Asuma-sama. Thank you for your help." Ishihara Sho remained calm, put on a friendly smile, and handed the plastic bag he was carrying to Asuma, speaking politely.

"You're a student of Hong?" Asma asked, taking the plastic bag with surprise.

“I never formally became an apprentice to anyone, but Master Hong has given me a lot of guidance in illusion magic, so you could say I’m barely considered Master Hong’s student,” Ishihara Akira replied.

"Asuma, who is it?!" Kurenai Yuhi's voice rang out from inside the house.

“A kid named Ishihara Sho said he’s your student and brought you a midnight snack,” Asuma called back into the house.

“Oh, then bring the things in. He’s my student,” Kurenai Yuhi replied.

"I understand." After a pause, Asuma turned to Ishihara Sho, who was standing outside with a smile, and said, "Then I thank you on her behalf."

"Lord Asuma, you're too kind. I won't disturb your time with Ms. Kurenai any longer. Have a wonderful day." With that, he turned and walked to his apartment door, took out his key, opened the door, and went inside.

"Crack, bang!"

"Bang!" Asma glanced at the convenient door, closed it, and carried his things back to his room.

"Hey, this is a late-night snack your student brought you." Asuma walked up to Kurenai Yuhi, who was sitting at the table, and placed the snack in front of her.

"Is this why you asked me to investigate him?" Asuma sat down next to Kurenai and said, "You want to take him as your apprentice?"

That's right. The reason Asuma appeared here at this time was not only because he had just finished his own business, but also because he was there to deliver the investigation report on Ishihara Sho to Kurenai.

After all, it's more convenient for Asuma to use the Sarutobi clan's power than to investigate himself, and it would also allow him to gather more detailed information.

“I have that idea.” Kurenai ignored the delicious food in front of her and continued to look through the documents in her hand that contained information about all of Ishihara Sho’s activities from birth to the present.

"Can you manage it all?" Asuma asked curiously. "You know, the annual graduation of the Ninja Academy students is just around the corner, and according to tradition, outstanding students will be assigned special Jonin instructors. Moreover, both the old man and the Hyuga clan intend to appoint you as their instructor Jonin. What will happen to this kid then? Will you just leave him to his own devices, or will you tutor him privately?"

"It will probably be private instruction," Kurenai Yuhi thought for a moment and said.

"Private tutoring... well, that's not impossible. This little guy lives right next to you, so it's quite convenient to tutor him." After a pause, Asuma asked, somewhat puzzled, "By the way, I remember this area you live in is a special housing complex built by the village to house the families of ninjas so they could focus on their missions. Why is he living here? Are his parents also ninjas from the village?"

"They were ninjas, but they all sacrificed themselves twelve years ago." Kurenai Yuhi tossed the documents aside after finally finishing reading them.

"You mean, the Nine-Tails?" Asuma asked, his expression shifting slightly.

"Hmm." Kurenai opened the box of late-night snacks that Ishihara had brought back for her. She saw the bright red and fragrant takoyaki inside and happily grabbed the toothpick stuck in it, putting the takoyaki into her mouth.

"Is it delicious?" Asuma smelled the aroma and couldn't help but reach out and grab the toothpick on the dumpling.

"Slap. This was bought for me by Ishihara Sho." Kurenai Yuhi slapped away his hairy hand.

"He's not even your disciple yet, and you're already protecting him like this. If he really becomes your disciple, where will I have a place here with you?" Asuma said with a helpless bitter smile.

"Whose fault is that?"

“I had a mission,” Asuma said softly.

"Others have missions too, but look at what they do! After completing their missions, they all buy local specialties to bring back as souvenirs for their loved ones. If that's not possible, they'll at least go to the flower shop in the mountains to buy some flowers. But what about you? Have you ever bought me any of these things?" For some reason, Kurenai Yuhi felt an inexplicable anger urge to vent today, complaining to Asuma.

"Uh..." Asuma was taken aback, but he knew that he had not done a good job, so he did not dare to refute it and honestly admitted it.

"Let's leave those aside for now. Just talk about our relationship. What's so shameful about it that you don't even dare to announce it? Is it because I, Kurenai Yuhi, am not good enough for you, Asuma, or is it because my background is inferior to yours, the son of the third generation and a young master of the Sarutobi clan, that you have to keep it a secret?" Kurenai Yuhi pressed on relentlessly.

“You just became a Jonin, and now you’ve revealed your relationship. I’m afraid people will misunderstand and think you got promoted because of me,” Asuma explained patiently.

"What about before? Why didn't you mention when I was still a Chunin?!" Kurenai Yuhi pressed.

"You forgot, back then I was one of the Daimyo's Twelve Guardian Ninja, and I wasn't even in Konoha," Asuma said helplessly.

"Don't even mention your Twelve Guardian Ninja. You, the son of the Hokage, risked the Third Hokage being smeared and gossiped about, and ran off to the capital without a word to become one of the Twelve Guardian Ninja. Did you ever think about the Third Hokage's feelings at that time? Did you ever think about the possible impact your actions might have on Konoha?"

"Uh...we were talking about our own things, how did we end up talking about the Twelve Guardian Ninjas again?" Asuma quickly corrected, sensing that things were getting out of hand.

"I'm talking about our relationship! Since you're worried that exposing our relationship will affect my reputation, why don't you think about the impact of you becoming one of the Twelve Guardian Ninja? I don't mind that you left me alone in Konoha for several years, and I'm still willing to continue talking to you, but you're making excuses for all sorts of reasons. It really makes me suspicious that you're playing some kind of trick," Kurenai Yuhi said, dissatisfied.

"What tricks can I possibly play?" Asma protested.

“Stay single and attract other women who know nothing about you, or who are after your family background, to get close to you, or wait for three generations to find you a wife of equal social standing,” Kurenai Yuhi said sarcastically.

"I'm not as bad as you make me out to be!" Asma said, somewhat angrily.

"Who would know?" Kurenai Yuhi, who was in a bad mood all day, scoffed without hesitation.

"You! You're utterly unreasonable. Alright, it's getting late, and I have other things to take care of tomorrow, so I won't disturb your rest any longer. You should also calm down. I'll come back to talk to you again tomorrow after I'm done with my work. I'm leaving now." With that, Asuma turned and left through the entrance, changed his shoes, and left Kurenai's house without hesitation, disappearing into the thick night.

"Phew, finally got rid of them." Seeing this, Ishihara Sho let out a long sigh of relief.

His extra effort was worthwhile.

Chapter 64 The Book of Seals

Before we knew it, the day of the Ninja Academy graduation exam arrived.

"The exam is here... which means that Naruto stealing the Scroll of Seals from the original story should have happened by now." Ishihara Akira stopped what he was studying and looked out at the bright sky on the balcony, muttering to himself.

The Book of Seals is a database-like collection that records all forbidden techniques, special ninjutsu, and outlines of most dangerous research data from the founding of Konoha to the present.

Normally, this item would be kept under the Hokage's nose and carefully stored under the surveillance of the elite Anbu!

In other words, under normal circumstances, unless there is a sufficiently high-level mole, or an event like the Konoha Crush that could throw the entire village into chaos occurs, it is simply impossible for such items to be stolen or lost.

But it was lost; it was stolen by a student who hadn't even passed the ninja graduation exam and hadn't even earned the rank of genin.

This is very abnormal and shows obvious signs of being orchestrated.

And that is indeed the case.

But what does this have to do with Ishihara Sho? In any case, what he cares about is only a few ninjutsu recorded in the Book of Sealing, not the Book of Sealing itself. Therefore, he feels that he can still take advantage of this opportunity to make some moves.

"Perfect timing! The chameleon I asked Tiantian to find for me a couple of days ago has arrived."

As he spoke, Ishihara Akira stood up, walked to a corner of the living room, looked at the small lizard kept in a closed box with ventilation holes, and with a thought, he blasted his mental power into the chameleon's consciousness, suppressing its original soul will and turning it into half of his own clone.

Then, Ishihara Yu opened the box, reached out, and took out the chameleon, which was no longer resisting him, and placed it on his clothes.

Instantly, the chameleon's skin began to change color, and gradually, the chameleon, whose outline was still vaguely visible, disappeared into the air.

Then, Ishihara Akira turned around, walked to the entrance, changed his shoes, opened the door, and went out.
