The Demon King, reborn in Japan as a monk

"Release!" Thinking she was under an illusion, Tenten broke free of her hand seals and shouted sharply.

But it didn't work!

Because Ishihara Sho's hypnosis technique is not like the genjutsu in the Naruto world, but a spell that works by disrupting the chakra of the target, it directly affects the target's mind. Therefore, although the vibration of chakra has the effect of shaking the mind, it is still somewhat insufficient in the face of Ishihara Sho's mental power, which is currently stable at LV3.

So the next moment, Tian Tian's eyes became vacant, and she entered a state of being controlled.

"Close the door," Ishihara Akira said with a slight sigh.

"Crack, bang."

"Teach me how to refine chakra." Without wasting any words, Ishihara Sho directly ordered Tenten, who was only wrapped in a large white towel and whose black hair was naturally loose.

"Chakra comes from the 130 trillion cells in the human body..."

Next came the familiar theoretical instruction. After covering the theoretical content that Ishihara Sho was already generally familiar with, Tenjo began to explain the specific methods of chakra refinement.

First, let's talk about hand seals. Here, we'll focus on explaining the meaning and uses of the twelve hand seals.

Ishihara was quite skilled in this area, so he quickly learned the hand seals of the Twelve Hand Seals and, under Tenten's guidance, formed the hand seals used to refine chakra.

Then there are more specific operating methods.

In other words, it's a method of exploitation—it sounds similar to meditation, but the core of it is exploiting cellular energy!

This is probably why the ninjas in the Naruto world don't live long.

Such practices that disregard cell lifespan may be acceptable once or twice, as they can be compensated for through food and therapy. But what happens if they occur repeatedly?

Isn't that just wasting your own life?

Naturally, a ninja's peak years are also short-lived. Often, once they pass 30, they become like an engine that has run out of oil, unable to exert their strength anymore...

Unfortunately, this is the reality of the ninja world. Unless you don't want to become a ninja, you have no choice but to risk your life along with everyone else.

The most frustrating thing is that some people, even if they want to risk their lives, don't even have the chance.

For example, Ishihara Sho sat there for more than ten minutes but still couldn't extract any chakra.

Chapter 44 Occupation and Consumption

"Refine your chakra once and show me." After persisting for a while and still achieving nothing, Ishihara Sho stopped refining his chakra and ordered Tenten, who was being controlled in front of him.

Tenten didn't resist. She went straight to the bed, sat down, formed hand seals, and began refining her chakra.

Ishihara Sho then released his spiritual power to examine Tenten's body in a more detailed way.

Unfortunately, his spiritual power was not the divine sense of a cultivator. Although he could also probe the outside of objects, he could not see through the surface of objects to their interior like a true divine sense.

Therefore, all you can see is loneliness.

Upon seeing this, Ishihara Shō frowned. After hesitating for a moment, he decisively channeled his mental energy into Tenten's mind...

Unexpectedly, this time he himself entered Tian Tian's body.

Tian Tian immediately straightened up and opened her eyes.

"Hmm?" Tian Tian's face showed a puzzled expression, and her eyes began to brighten, as if she had broken free from the state of being controlled by hypnosis.

"I... have taken over Tenten's body?" Tenten asked in astonishment as she looked around and found no trace of her own body.

But thinking about it again, it doesn't seem like something that's hard to understand!

After all, he is a demon. This time, his entry into the dimensional world looks like a time travel, directly crossing time and space from the dream world to the Naruto world. He has a physical body, but his essence has not changed at all. He is still his own spiritual body. Therefore, physical form is an illusion to natives like Tenten who live in the Naruto world!

This is why he can use the Heavenly Demon Transformation technique so smoothly and naturally.

Since it has no substantial, physical body, it can change however it wants.

I was just misled by appearances and didn't notice it before.

—Who told him to be a newbie in the Heavenly Demon realm?

As a celestial demon, infiltrating other people's bodies, seizing their possessions, interfering with their actions, and guiding them into demonic possession are the celestial demon's duties and sources of power; otherwise, they would be too unworthy of the title "demon" bestowed upon them.

That's why, in what he thought was a dream-entry operation, he directly entered Tian Tian's mind, suppressed her consciousness, and thus seized control of her body.

“That makes my actions much easier,” Ishihara Akira said with satisfaction.

However, he didn't forget the main task. After getting used to Tenten's body for a while, he decisively repeated the previous actions and began to refine his chakra.

Even if, this time, it was his mental energy that was being refined.

However, chakra is not considered a kind of spiritual power. It is only said to be a product of the combination of spiritual energy and physical energy. Therefore, even though the spiritual energy was changed from Tenten's spiritual power to Ishihara Sho's, there was not much delay when they were combined. Chakra was quickly generated and began to circulate in Tenten's body.

This allowed Ishihara Sho to experience firsthand the process of refining and utilizing chakra.

Then, Ishihara Akane decisively broke free from Tenten's body and returned control of the body to Tenten.

Tenten was stunned for a moment, and just as she was about to resist, her consciousness was once again suppressed by Ishihara Sho's hypnosis...

"Since my body is fake, that means my current form of existence is entirely a spiritual construct! In the Naruto world, it's a Yin Release creation, basically the same as the Susanoo created by the Uchiha clan after awakening the Mangekyou Sharingan, even inferior to Black Zetsu! So, to change this, we need to find a way to convert Yin Release into Yang Release power..."

"This sounds a lot like the Transformation of the Yang God, doesn't it? Could it be that I have to refine myself into a ghost immortal or cultivate myself into an earth immortal just for the sake of chakra? If I could achieve that, why would I bother cultivating chakra? I could just cultivate merit all the way and become a celestial immortal, wouldn't that be enough? Even if Mara came back, I could kill him without even having to think about it!"

After all, according to the orthodox Taoist system, Buddha was just a celestial being.

"Forget it, let's try absorbing external chakra first and then guiding and refining it."

"Tenten, channel your chakra into my body. Don't stop until I tell you to." With that thought, Ishihara Akira turned to Tenten beside him and said.

"Okay." Tenten responded, placing her small, delicate hands—which were actually covered in calluses and wounds—on Ishihara Sho's chest and channeling her chakra into Ishihara Sho's body.

Without hesitation, Ishihara Shō immediately closed his eyes and began meditating, refining his chakra according to the method he had been taught every day.

Believe it or not, perhaps because of the involvement of Tenten's chakra, her energy made up for Ishihara Sho's lack of Yang Release attribute, and soon he generated his own chakra energy within his body!

However, it was converted by consuming Tenten's chakra.

In other words, the amount of chakra that is transported into his body each day determines the amount of chakra he refines. If he tries to generate more, he will be unable to do so due to a lack of physical energy, and his chakra production will stop at the current level.

“Alright, let’s stop.” Ishihara Sho sighed.

"Could it be that I really have to possess a target to serve as my physical body in this world, to carry and refine chakra?" Ishihara Sho muttered to himself, his mind full of questions.

Then he sat there pondering the information about the Naruto world, thinking about other possible ways to replenish his Yang Release energy...

He actually thought of it—

There are two ways. One is to eat them! Like the native animals in the Naruto world, eat creatures containing chakra cells—like ninja beasts.

While this is difficult to fulfill, the Death Forest does exist, but supplying it is rather troublesome.

Otherwise, they'd have no choice but to eat 'people'...

Second, learn from the Akimichi family: eat like crazy, eat all kinds of things, eat until you're about to die, or as long as you don't die from overeating, don't stop eating. Then, use a method similar to the Taoist practice of refining essence into qi to squeeze out any possible Yang Release energy from the meat in your stomach, and combine it with your own spiritual energy to create your own chakra...

"So, he just can't live without his mouth, huh?" Ishihara Sho muttered to himself, utterly speechless.

“Every day, I’ll open a path through your hands.”

Without hesitation, Tian Tian immediately got out of bed, took out a kunai from the closet, and slapped it against her own palm.

Ishihara Sho followed closely behind, grabbed Tenten's hand, and like an old vampire, licked the blood from Tenten's wound, while closing his eyes and refining his chakra...

It succeeded, but the method...

It's simply not something that Ishihara Sho could accept.

"It seems we can only start with ordinary food."

"So, I'm not only going to become a big eater, but also a carnivore who can't live without meat?"

Although, given his current demonic form, he doesn't need to worry about gaining weight.

"It seems that this is the only way."

Chapter 45 Seeking Help

"But where will the money come from?"

As an outsider, he had no elders to rely on and no resources to utilize.

Immediately, Ishihara Akane raised his head again and looked at the pretty and cute Tenten in front of him.

"Choosing her as my target was definitely the right choice."

Of course, Tian Tian's parents can't be overlooked either if he wants more control over the funds; they need to be won over as well!

Otherwise, her parents wouldn't be able to remain indifferent if she were to use large sums of money every day.

So, after using her psychological manipulation abilities to adjust the emotional distance between the two to a near-perfect fit, Ishihara Akane decisively began to instill her presence in Tenten, whom she controlled, saying that she was the most important person to her, that she had to obey her every word, and that no one else could know about their relationship.

After finishing everything, Ishihara Akira told Tenten to go back to bed and left Tenten's room. He then found Tenten's parents and used the same method to instill his own existence and their leniency towards Tenten into their minds, in order to facilitate his next move.

Then, Ishihara Akira returned to Tenten's room, glanced at her lying on the bed, and with a flash, entered Tenten's mind again, found her consciousness, and continued to influence her with the power of the Heavenly Demon...

Just as dawn was breaking and Tenten was getting ready to exercise, Ishihara Akane left Tenten's consciousness space again and appeared directly on Tenten's bed. She lay down on her side facing Tenten and put her arm around her body.

"Ishihara, what are you doing in my house?" Feeling a tightness in her chest, Tenten turned her head and noticed Ishihara's presence. She sat up abruptly and questioned Ishihara loudly, who seemed to have been awakened by her movement.

"Didn't you invite me here?" Ishihara Akira sat up and rubbed his eyes in a mock-serious manner.

"I invited you? When?" Tian Tian asked blankly.

"Just yesterday, when you came back from your shop, you ran into me on the road and said it had been a long time since we last met and wanted to invite me to your house for a visit, so I came back with you. Don't you remember?" Ishihara Akira asked, feigning surprise.

"Even so, how did you end up in my bed?" Tian Tian frowned and thought for a moment. She vaguely remembered something similar and couldn't help but ask.

"It's all because you asked me to come up and play with you, and then you insisted on showing me your throwing skills. I refused, but you insisted, and in the end you even hurt yourself... If you don't believe me, look at your palm, there are still wounds left by the kunai." After a pause, Ishihara Akira added, "And what's even more speechless is that you didn't check beforehand when you picked up the kunai. You didn't even notice that it was covered in anesthetic, and then you were knocked out by the anesthetic. I had no choice but to stay and take care of you, and that's how this happened."

"Why don't my parents take care of me? And didn't they say anything when you stayed?" Tian Tian asked, still not quite believing it.

"I went to them, but they said they weren't ninjas and didn't know much about this kind of thing, so they asked me to help them. They didn't urge me to leave, and that's how it ended up like this."

Tian Tian remained silent for a while, then carefully examined him before decisively turning around and running out of the room.

"I'll go ask them!"

"Phew... thankfully, I already tampered with them yesterday."
