The Demon King, reborn in Japan as a monk

"You can't refine chakra anymore?" Iruka asked, somewhat incredulously.

"Come on, let's go to the office first."

The two then went to the classroom office.

“Sit here now and refine your chakra once,” Iruka said, pointing to the stool next to him.

“Okay.” Ishihara Sho sat down as instructed, formed the hand seals for refining chakra, and began refining chakra in front of Iruka.

Naturally, it has no effect whatsoever.

Iruka placed his hand on Ishihara Sho's shoulder, carefully sensing the changes in his body—

As expected, no chakra was generated.

“Alright, come with me to the hospital. If it’s indeed a problem on your end and there’s no way to recover, I’ll report to Lord Sandai and have you withdraw from school and regain your civilian status,” Iruka said to Ishihara Sho, who had just opened his eyes.

Ninjas, after all, are a military unit. Although not regular soldiers, they were an important part of the Ninja World War. Therefore, the students in the Ninja Academy also became a quasi-military unit! So, enrollment was relatively easy, since everyone was going to be cannon fodder anyway, and the higher-ups weren't too strict with them. But if you were to drop out midway...

Especially for someone like Ishihara Sho, who withdraws from school just before graduation, Konoha will suspect that he is exploiting Konoha and has other secrets.

Unless your grades are not good enough to be a ninja, any student who drops out of school without a valid reason must report it to the higher-ups.

These students, who have mastered chakra refining techniques and received almost all the training in ninja combat, are potential dangerous individuals and future recruits, so Konoha cannot afford to be careless.

Afterwards, Iruka greeted the other teachers in the office and took Ishihara Sho to Konoha Hospital to have the medical ninja there examine Ishihara Sho's body.

The result is, of course, nothing more to say...

After all, although he is a demonic being, a spiritual being, and a Yin Release creature, he gives people the feeling that he is real and has a physical body. It's just that without the participation of Yang Release, everything is fake. This can deceive the medical ninjas' examination, making them have the wrong perception and filling in the missing part of Ishihara Sho's plan—proof!

"Well, it seems you're really not suited to be a ninja anymore," Iruka sighed helplessly after receiving confirmation.

"So, are you coming back to school with me later, or going straight home?"

“Let’s go back to school. After all, I haven’t received my permission yet,” Ishihara Akira said with a faint smile.

"Okay. Let's go back then."

After saying that, the two left Konoha Hospital and returned to the Ninja Academy.

However, the two then separated. One returned to class to continue attending lessons, while the other went to report to the third generation and helped Ishihara Akira obtain a so-called withdrawal certificate.

Moreover, it was done very quickly. Around noon, Ishihara Sho's withdrawal permit was issued and handed to him by Iruka.

"Thank you for your help, Iruka-sensei."

"This is simply my duty. But what about you? What are your plans for the future?"

"I want to rest at home for a few days first, and then see where there is a shortage of people, and then apply for a job. I just need to survive first."

“If you encounter any difficulties, come to the school and ask the teachers for help. Although I’m just a Chunin and don’t have many connections, I can still easily help you find a job,” Iruka said confidently.

“Okay.” After a pause, Ishihara Akira continued, “Then I’ll take my leave.”

"Go."

After that, Ishihara Sho officially left the Ninja Academy and began wandering around the area near the academy...

If he hadn't sensed a strange surveillance presence, he might have already run to Tian Tian's house and officially become a live-in son-in-law.

"The art of telescopes, huh..."

Fortunately, the Third Hokage's observation was merely out of curiosity and a desire to see him, a rare student in Konoha's history who had chosen to voluntarily withdraw from the school. So, the watchful gaze disappeared in no time, allowing Ishihara Akira to breathe a sigh of relief.

"If they keep monitoring me, I'll really be in a difficult situation."

After all, he was an outsider. Although he seemed to have a status in Konoha for various reasons, he had no idea what the situation of this status was.

For example, Ishihara Sho had no idea about the essential thing like a place to stay or a place to live. If the Third Generation's surveillance continued, he couldn't possibly not go home for that reason, could he?

In that case, even if the Third Hokage doesn't care about a dropout like himself, he'll probably still send the Anbu to investigate him thoroughly.

Not to mention, he later wanted to possess Choji's body and steal his family's Yang Release Chakra Refining Technique and Expansion Technique. If there was an unseen eye following him, how could he carry out his actions?

Should we directly force our way in and expose ourselves?

……

After wandering around for a while, Ishihara Akira found a barbecue restaurant and went inside.

"Boss, I want this, this, and this," Ishihara Akira said to the waiter, pointing to the menu in his hand without any hesitation.

With 200 million yen in his pocket, he simply couldn't believe he couldn't afford even a barbecue.

Perhaps because it wasn't mealtime, there were relatively few customers in the restaurant. Since the main operation of grilling meat is done by the customers themselves, the restaurant staff only needs to bring up the cut and marinated meat. So, in just a few minutes, Ishihara Akira's order was brought up, and then Ishihara Akira transformed into a grilling worker, placing the meat on the charcoal fire to grill.

"Let me see if my idea can succeed."

A moment later, the grilled meat was cooked through, and Ishihara Yu decisively picked it up, dipped it in sauce, wrapped it in a vegetable leaf, and put it in his mouth.

As the Chakra Refining Technique was activated, the energy remaining in the cells of the freshly eaten roasted meat was squeezed out and colliding with his own spiritual energy.

Well, it is useful, but the effect is minimal. It would probably take eating a hundred or so kilograms of food to extract a fraction of the chakra that Tian Tian casually infused into his body last night.

This explains why Choji and the Akimichi clan have been eating non-stop since they were old enough to understand.

The real reason is that the chakra obtained from food is pitifully small, making it inefficient...

It's an incredibly wasteful way to save money.

"I wonder if Choji's family's refining technique has any effect on improving the conversion efficiency of chakra extracted from food."

Chapter 48 Stealing

Having verified the feasibility and effectiveness of his idea, Ishihara Sho, after having a quick bite to eat, left the barbecue restaurant and continued to wander around the area near the ninja academy.

He hadn't forgotten what he was supposed to do next.

So after a long while, accompanied by the clamor of voices coming from the ninja academy, students from all grades began to run out of the academy.

One grade after another.

Soon it was the turn of the sixth grade that Ishihara Akira, the person she was impersonating, was originally attending.

Familiar classmates began to appear, and soon he found Shikamaru and Akimichi Choji walking together in the crowd. He activated his hypnotic field, making himself 'invisible' and moving to Akimichi Choji's side. Then, in a flash, he entered his body.

Dingci was stunned and stood still.

"What's wrong?" Shikamaru asked, puzzled.

"It's nothing," Choji said, shaking his head.

Yes, Choji was still the same Choji at this time. This was because Ishihara Akira did not use the Tenma and his own powerful mental strength to suppress Choji's consciousness and soul. Instead, he seemed to be residing there, hiding himself and letting Choji do as he pleased. He planned to uncover the secrets of the Akimichi family's Yang Release ninjutsu after Choji fell asleep at night.

……

Despite being a fat man and not being the type to enjoy fighting, Choji is still very diligent when it comes to training.

Although he wasn't as crazy as Rock Lee, nor as enthusiastic as Sasuke, he was far better than those guys who only worked sporadically.

Therefore, upon arriving home, Choji went straight to the clan's training grounds to begin a day of practicing the clan's secret techniques.

First, naturally, is the foundation of the Akimichi clan's secret technique: the Multiplication Technique!

This was also the ninja that Ishihara Sho was most concerned about, so he unceremoniously released his spiritual power to observe the changes in Akimichi Choji's chakra when he used ninjutsu, as well as the specific way the ninjutsu was released.

So the next moment, Choji Akimichi's body rapidly swelled up...

Instead of growing completely larger, it swelled into a giant ball of flesh, shrinking its limbs and head inside, and rolled rapidly in one direction like a ball.

Human Bomber Tank!

It is also the only offensive ninjutsu of the Akimichi clan that Choji Akimichi can currently master.

As for the others—

Techniques like the Super Multiplication Technique all require an exaggerated amount of chakra to unleash. With the amount of chakra that Akimichi Choji currently possesses, he cannot perform ninjutsu of that level!

However, the partial multiplication technique still works without any problems.

After completing a round of training with the Human Bomber Tank, Choji Akimichi sat down on the ground, panting for a while before standing up again to practice the Partial Expansion Technique, which he had recently learned but was not yet very proficient in.

The palm grows larger, then returns to normal, grows larger, then returns to normal...

After five or six cycles, Choji Akimichi's chakra was exhausted, so he sat back down on the ground and lay flat on his back.

As for refining chakra and such...

In the ninja world, it's not acceptable to immediately refine chakra after strenuous training.

After all, chakra is not internal energy. It doesn't mean that you can improve the recovery speed and quality of internal energy without loss after performing extreme operations.

While it is possible to do so, doing so would only accelerate the depletion of one's physical health and lifespan, making an already short-lived body even shorter and worse off!

What do you think happened on Xiao Li's side?

If it weren't for the Jonin Might Guy helping him out, using all his earnings to buy training resources and medicine for Rock Lee, do you think he would be alive today?

This is why his physical abilities and progress in mastering the Eight Gates stopped abruptly after his serious injury, and remained largely unchanged until Boruto.

They were exploited too much, which stifled their potential.

Afterwards, Choji Akimichi returned home, found his favorite snacks, and began to eat them heartily...

And this was just a small appetizer before the main meal. It wasn't until the meal itself that Ishihara Akira understood exactly how the Akimichi family cultivated their chakra.

The table is covered in meat!

A wide variety of high-calorie foods.

Aside from some side dishes that were vegetables, the main courses were all meat, and even the staple food was a huge leg of meat, like the kind of huge leg of meat that Goku ate after the martial arts tournament in Dragon Ball. It was a huge pile, like a small mountain, which made Ishihara Yuu's mouth water with sadness...

With these resources, Ishihara Akira admits that he simply can't catch up to them!

After that, Ishihara Akane turned his attention back to Choji and carefully observed how Choji digested and utilized food, as well as the Akimichi clan's specific methods for extracting chakra and Yang Release energy from the residue inside food. He memorized them all and made them his own.

"Hmm, in another day, I'll be able to master the Expansion Technique, the Partial Expansion Technique, and the Akimichi family's chakra and Yang Release extraction techniques. Then I'll possess Shikamaru and steal their Yin Release extraction methods..." Ishihara Akane thought to himself with a heart full of joy.

Then, late at night, Ishihara Akira, full of anticipation, used his power to influence Akimichi Choji's consciousness, controlling him and extracting more detailed information about the Akimichi clan's secret techniques and cultivation methods from him, making the copying process increasingly smooth.

……

The following day, Ishihara Sho followed Akimichi Choji back to the Ninja Academy, and the moment he greeted Shikamaru, he detached from his body and entered Shikamaru's consciousness.
