Levitation Technique

During training, Uchiha Hikari naturally made use of her Sharingan.

Mainly for its dynamic vision and motion-copying abilities.

And her Shadow Clones.

At first, Korin thought she was using some trick like the "Four Body Fist" to cut corners, and he was somewhat displeased. But after Uchiha Hikari sincerely explained how Shadow Clones worked and how their experiences returned to the original body after being dispelled, he said nothing more. He merely raised the intensity of her training without showing it.

In the original story, it took Master Roshi three years to obtain the Super Sacred Water, while Little Goku took three days.

That did not mean their talents differed by hundreds of times.

That was because Korin's power far surpassed theirs at that point, and he could use the Levitation Technique. The duration of the training was entirely up to Korin. If he truly wanted to stop someone, then they would never be able to seize the sacred water until their power had risen close to his.

Uchiha Hikari did not mind this.

Since she was already here, there was no harm in learning a little more.

After staying atop the tower for so long, food became a major problem.

On the first day, Korin casually tossed her a bag of Senzu Beans to stave off hunger.

However, Uchiha Hikari carefully put away those Senzu Beans, then tossed out two of the capsules she had gotten from Bulma. She set up pots, bowls, and a stove in one corner of the tower roof, cooking every morning and evening and sharing some of the finished meals with Korin.

Naturally, the ingredients had all been purchased in advance. The capsules maintained a vacuum environment, so there was no need to worry about food spoiling.

There was also a small room of over ten square meters for her to bathe and sleep in.

Finally...

On the day the seventh week ended, Uchiha Hikari successfully seized the Super Sacred Water.

And she could feel that the Chakra within her seemed to have changed somewhat.

It seemed...

As though something else had been mixed into it, making it tougher and more flexible?

"Although it's a little different from what I expected, you should have already mastered 'Ki.'"

After dinner that day, Korin suddenly spoke.

"Really?"

Hearing Korin say that, Uchiha Hikari was still somewhat uncertain herself. "Then can I use the Kamehameha and the Levitation Technique now?"

Korin licked his paw. "I don't know much about the Kamehameha, but you can try the Levitation Technique."

The principle behind the Levitation Technique was not actually complicated.

Put simply, it worked somewhat like a helicopter: one released one's own Ki beneath one's feet to support the body in midair, then altered the direction of that Ki to move freely at will... The main difficulty lay in controlling Ki, and it had something in common with the water-walking training in the Naruto world.

Uchiha Hikari tried dozens of times.

Just as she began to doubt whether she could learn it, a wondrous sensation suddenly arose. The next moment, her body lifted slightly and floated in midair.

"?!"

The instant her mindset shifted, Uchiha Hikari fell from the air.

Yet her eyes shone with delight.

It really worked?!

Korin, who had been observing from the side, nodded. "It seems you've grasped the basics. Next, you only need to remember how you used it just now and practice until you become proficient."

"Mm..."

Uchiha Hikari carefully sensed the condition within her body for a moment, and her expression became a little strange.

She was certain that what she had just used was the principle of the Levitation Technique, not Iwagakure's Ultra-Light-Weight Rock Technique, which achieved flight by altering one's own weight. Yet this method of using Chakra should have been impossible under the rules of the Naruto world. Even Minato Namikaze had never seen it—setting the Otsutsuki family aside.

So...

What exactly had the energy inside her been cultivated into?

A mutated version of Chakra? Or a mixture of Chakra and Ki?

After thinking about it, Uchiha Hikari gave up.

It was not important.

No matter how this energy changed, it was ultimately hers. All she had to do was work hard to control it.

"Then... it's about time I left for a while."

Korin still had many special techniques she had not learned.

For example, the ability to sense Ki, as well as that mind-reading technique she did not know whether he could teach others...

But Uchiha Hikari had been on the tower for too long, constantly maintaining high-intensity training. Physical injuries could heal quickly, but mental exhaustion was difficult to eliminate. She needed to balance work and rest, lest she push herself too hard.

Before leaving, Uchiha Hikari tried asking Korin for a Flying Nimbus.

Well... she could not ride it.

After all, having been born as a weapon and burdened with countless lives, she could hardly be considered a person with a pure heart.

With no other choice, Uchiha Hikari asked for another large bag of Senzu Beans. Then she gave Korin her cooking set, along with several large boxes of uneaten fish. After agreeing to come back for guidance whenever she had time, she finally said goodbye and left.

During this time...

Quite a few things also happened in the chat group.

After returning from Pilaf Castle, Bulma told the group about her recent travels.

Both Minato Namikaze and Tanjiro were very curious.

Minato Namikaze was not too surprised, since the Naruto world also had something called the Box of Paradise, a ninja tool left behind by the Sage of Six Paths that was said to grant wishes. The way it granted them was just a little off...

But the Demon Slayer World where Tanjiro lived had very few supernatural things, so he found it unbelievable.

Iron Head Kid: Miss Bulma, can those things called Dragon Balls really grant any wish? Even resurrecting the dead, or restoring humans who have already turned into monsters?

Bulma: This... should be possible, I think.

Bulma: Does Tanjiro have someone he wants to bring back to life?

Iron Head Kid: Mm... I want to turn Nezuko back into a human!

Bulma: ?

Forever with Sis: I remember Miss Hikari once said that Tanjiro's world has a kind of nonhuman creature called "demons." They are transformed from humans and can spread through blood... Tanjiro's sister was probably attacked by one of those creatures and turned into a demon, right?

Iron Head Kid: Yes. That's why I joined the Demon Slayer Corps...

Nameless: If you only want to turn your sister back, there's no need to seek out Dragon to make a wish. In your world, a doctor is already researching that, and it is expected that an effective medicine will be developed soon... By the way, you haven't met Miss Tamayo yet, have you? If you want to resurrect anyone else, I'm afraid only those who died within the past year might be able to return.
