Naruto: I created martial arts in the ninja world

Seeing the fist slowly coming towards him, Kushina felt that the air around him was stagnant, and his body was not in control.

A heroic man appeared in his mind. He stood on the top of the mountain, looked at the world, and sighed, "Invincible is so lonely!".

Jiu Xinnai stood motionless on the spot, and it took a long time before she came back to her senses.

Seeing Xia Wu sitting cross-legged in front of the court, Jiu Xinnai moved his mouth.

"That is……"

"That's my boxing intention, that person is my future, this boxing technique is called "Human World", do you have any experience?"

Xia Wu nodded, affirming Jiu Xinna's thoughts.

That was what he looked like in his previous life, but at his level, he is completely able to control his body, so it's not wrong to say that he is the future.

"Why do you practice boxing?

What would you be like if you didn't practice boxing?

Kushina, if you figure this out, everything will just happen naturally.

But we must pay attention, the heart must be sincere, and the fist will not deceive oneself. "

Then, Xia Wu remembered another thing.

"If you still want to feel the fist intention, you can go to the sealed space, where there is a fist intention left by me."

Chapter 20 Wetbone Forest

Konoha Hospital.

"Xiao Xia Wu, I'm here to find Master Tsunade again!"

Xia Wu was walking on the road, and occasionally someone greeted him.

After all, in the past year, he often went to the hospital, and everyone knew him.

He came to Tsunade's office, and as soon as he entered, he saw that Tsunade was signing some documents.

"Busy again! Tsunade-sama."

"Yeah, it's so boring to sign documents every day! I want to go drink." Tsuna didn't raise his hand, and complained, "By the way, what are you going to ask today?"

Xia Wu shook his head and said:

"My research on fairy art has hit a bottleneck, so I want to ask you some questions."

Hearing this, Tsunade couldn't help being taken aback:

"Xianshu, you are actually studying Xianshu? Do you want to practice Xianren mode? Although your chakra control is sufficient, but the amount of chakra is too small, it will be eroded by natural energy."

She pondered for a while and said:

"I don't know much about immortal arts. Grandpa said that my physique is not suitable for cultivating immortal mode. You can only ask the immortal slug yourself about this question."

Saying that, Tsunade sealed and summoned a huge scroll.

"This is the psychic scroll of Wetbone Forest, through which you can sign a contract with the slug."

Xia Wu looked at the scroll handed over by Tsunade and said:

"This is the psychic scroll of Wetbone Forest, one of the three holy places. Is it really okay to hand it over to me?"

Tsunade waved his hand and said:

"No problem, I originally planned to give you the scroll as a graduation gift, but now it's just ahead of schedule, and with your talent in medical ninjutsu, you may be more suitable for slugs than me."

Xia Wu didn't hesitate, and opened the scroll directly.

Most of the scrolls have the names of the Senju Clan, the name at the end is Tsunade, and the name further on is the name of Senju Hashirama.

He bit his finger, wrote his name at the bottom of the scroll, and pressed his handprint.

The moment the fingerprint was pressed, the space changed, and Xia Wu disappeared in place.

Xia Wu opened his eyes, the surroundings were pale white, all the trees were bare, and there were some small slugs crawling on them.

He took a breath of fresh air here, and felt that his body seemed to be a lot lighter.

"Are you the new contractor?"

Xia Wu turned his head to look at the place where the sound came from, and found a slug the size of a man in front of him.

"Slug Immortal, hello, I'm Uehara Xia Wu."

"You can just call me a slug. I'm not a fairy, but a slug who has always been good at fairy arts."

The slug seemed quite kind and gave Xia Wu a lot of respect.

"Slug, where is your body? I have something to find her."

The slug in front turned around and took it to the main body.

"Come with me, Lord Xia Wu."

Soon, Xia Wu followed her to a mountain range, looking at the huge slug fairy in front of him, Xia Wu was a little shocked.

It was hard to imagine that there would be such a huge creature in the ninja world, even Kyuubi was just a tiny dot in front of her.

The next moment, the huge head of the slug moved, she lowered her head slightly, and asked curiously:

"Lord Xia Wu, what do you want from me?"

"I've been researching the relationship between chakra and natural energy recently, and finally I found that chakra can be transformed with natural energy, slug, do you know how humans absorb natural energy?"

The slug mused:

"I actually don't know how humans absorb natural energy. I absorb natural energy more like instinct. Therefore, the immortal models of the three holy places will have animal characteristics."

"It's very similar to that fox!" Xia Wu said to himself.

"The slug taught me how to practice immortal mode, I want to experience the state of absorbing natural energy for myself."

Slug said worriedly:

"Lord Xia Wu, are you sure you want to practice immortal mode? This process is very dangerous."

"It's okay, I'm still very confident in my medical ninjutsu."

Looking at the confident Xia Wu, the slug did not refuse, but said patiently:

"Well then, if something goes wrong, I'll stop."

Xia Wu nodded in agreement.

Then the slug swallowed Xia Wu.

As soon as it entered the slug's body, a lot of mucus covered Xia Wu's body, and the natural energy was also converging towards his body.

As soon as his body came into contact with the natural energy, it immediately began to absorb it crazily.

Suddenly, Xia Wu felt that the surroundings were filled with light spots, he had never seen such a scene before.

He used his spirit to pull the light spot, and as soon as it entered his body, Xia Wu was awakened by the familiar feeling.

This is natural energy?

Recalling the state just now, and thinking that he had never been able to find a way to absorb natural energy, Xia Wu was a little dumbfounded.

He has already realized that the so-called method of absorbing natural energy is to achieve the state of harmony between man and nature, and only after entering the unity of man and nature can he perceive natural energy.

The reason why Xia Wu didn't perceive the natural energy was that his realm was too high!

He was able to achieve the unity of man and nature very early on, and later Xia Wu created another realm, I am the heaven and the earth.

No longer merged with the heaven and the earth, but I am the heaven and the earth, I mean the will of heaven.

Just because his divine will was too domineering, he was repelled by natural energy and could not absorb it no matter what.

If he hadn't been releasing divine will all the time, he would have succeeded long ago.

In fact, what Xia Wu didn't know was that if his spirit continued to grow stronger.

One day, he will be able to forcibly plunder the energy of the world.

As a result, it was this neither high nor low appearance that made him unable to comprehend and absorb it forcibly.

"Slug, let me out."

Once the problem is found, Xia Wu no longer needs the help of the slug.

"What's the matter, Lord Xia Wu?"

Without answering the slug, Xia Wu sat directly on the ground and instantly entered a state of being one with nature.

Feeling the rich natural energy around him, Xia Wu was extremely excited.

"Did you succeed in training so quickly? Even Zhujian is not so fast!"

Looking at Xia Wu who merged with nature, Slug was very curious.

Over the past thousand years, the slug has realized that the power of one person is small compared to the whole world.

But after meeting Xia Wu today and feeling his will, Slug thinks he might be wrong.

This man might change the whole world.

"I don't know what the future of Master Xia Wu will be like? What kind of changes will it bring to the ninja world? I really look forward to it."

After an hour, Xia Wu opened his eyes, frowned and said:

"Slug, can you use natural energy to unleash ninjutsu-like attacks?"

"Yes, Master Xia Wu."

The slug replied in a gentle voice.

"It seems that after the natural energy is absorbed by the human body, it needs to be transformed before it can be used, and it is also necessary to create a method to strengthen the natural energy through daily practice."

Xia Wu thought in his mind.

"Lord Xia Wu, I don't seem to feel the aura of Immortal Chakra on you."

There was a hint of doubt in Slug's tone.

"I have not fused natural energy with Chakra. I have always thought that the energy system obtained by extracting itself like Chakra is deformed, and I have also vaguely noticed that Chakra has a lot of hidden dangers."
