When Sakura Haruno first arrived in the Wet Bone Forest a month ago, she had no idea that Sasuke would have such an unfolding in Konoha at all.

At that time, as soon as she landed, she was almost startled by the loud voice of the slug immortal.

"Sakura Haruno...... I've been waiting for you for a long time. ”

Sakura Haruno raised her head vigorously and raised her slender neck before she found the head of the slug immortal from the towering clouds.

It was a sunny day, the sky was blue, a few clouds were floating high, and the July sun was shining brightly.

Sakura Haruno squinted her eyes and saw that the half-cut body of the slug immortal was lying on a huge tree, gnawing on the bark. Its translucent body stretched for thousands of meters, leaning against a tree like a skyscraper reaching into the sky, the dark green flesh wall almost obscuring her vision, and further up, until the apex of the sky, Haruno Sakura saw the midday sun and the two tentacles dangling on the slug's head.

Even though she had seen it once, Sakura couldn't help but hold her breath in front of the slug immortal's thick and majestic body.

As far as the eye can see, you can only see the dark green translucent soft flesh on the slug's body, and the slug immortal doesn't need anything else, just the physical ability that has grown to the limit can make people dispel all thoughts of fighting against it......

In front of it, the slender Sakura Haruno felt as small as an ant in front of a big tree.

As proud as she was, she also maintained awe in front of the slug immortals.

Sakura Haruno couldn't help but swallow her saliva, her raised neck swayed slightly up and down, and it took a while to calm down.

"Have you waited a long time? I'm sorry, Slug Immortal. Sakura smiled apologetically, but secretly thought in her heart, for an unconventional long-lived life form like a slug immortal, a year or two shouldn't be a long time......

"I wanted to treat you to lunch. The slug didn't raise its head, and said as it continued to gnaw, "But you haven't come here after waiting for a long time, so I'll eat it first." ”

It turned out that I just waited for dozens of minutes......

Sakura Haruno twitched and realized that she had made a mistake.

I thought that the existence of the slug immortal would wait for her for a year and a half or something, I really thought too much...... Is it because it is easy to get compliments and longings from others recently, so you habitually have delusions?

Embarrassed.

"I'm sorry, I was saying goodbye to the students just now," Sakura Haruno explained with an embarrassed smile as she stroked her hair, "You know, kids are always sentimental, and I-"

"But it's good that I left you a small bite," the slug immortal didn't notice what Haruno Sakura said, and said to himself, "It's not much, but with your human appetite, it should be enough for you to eat." ”

Bang!

A huge white object slammed down from a great height and landed in front of the girl, narrowly missing her.

It was a piece of white bark peeled from the giant tree, wider horizontally and vertically than Haruno's hands and feet, and as thick as three of her - two if you compare it to Hinata.

The bunch of words that Sakura Haruno wanted to say just now were suddenly smashed back into her stomach.

"That...... Slug Immortals," she said weakly, raising her hand, "we humans generally don't gnaw on tree bark......"

- Unless you chop krypton gold again at the beginning of the month.

"Eat it. However, the eating slug fairy did not listen to anyone else, and completely ignored the little little thing that was bouncing on it, trying to attract its attention.

Well, we can't expect a mollusk that has seen only three living humans in the last 100 years to understand what communication is and what emotional intelligence is.

The slug immortals eat only once a month, and at one time they can eat up the bark of half a giant tree and ingest hundreds of tons of organic matter. Although the Wet Bone Forest is large, it is still not vast enough in front of the Slug Immortal with an amazing appetite, if it eats it with its belly open, the speed of eating will soon exceed the growth rate of the giant tree in the Wet Bone Forest, so the Slug Immortal deliberately suppresses his appetite, so the monthly food time becomes particularly precious, and when something big happens, it is not as important as the Immortal's lunch.

So when it was over, the immortal remembered that there was a guest in the Wet Bone Forest today.

Sitting on that piece of bark, the bored Haruno cherry blossoms.

If it's a tsundere girl, she has been snubbed like this for a long time, and she is probably going to make a big noise at this time, right?

- Then you are wrong. Sakura Haruno is sure that not to mention that she has always been able to stabilize her emotions, no matter how willful and arrogant the little girl is, she will never dare to be presumptuous in front of the slug immortals.

"Ah, I'm sorry...... I get carried away easily when I'm eating. The slug fairy said softly, "Don't you eat it?"

Wait, soft ......?

Well, I can tell it's trying hard to be gentle......

But the thunderous roar, the aftermath was incessant, and the girl's ears were so vibrated that she couldn't feel any tenderness anyway.

"Humans don't eat tree bark, immortals. Sakura Haruno tilted her head and explained, opening her scroll, "You don't have to worry about me, I brought food here." ”

Because I heard that there was no normal food in the wet bone forest, Sakura's mother bought all kinds of delicacies and stuffed them to her, squeezing out a considerable part of the position of compressed dry food; in fact, it is already very good to be able to gnaw dry food, at least it is easier to swallow and digest than gnawing tree bark, and humans do not have the ability to digest cellulose. It is said that when Mt. Myoki entertained guests, he had a feast of insects, and he was really looking forward to the day when Naruto would practice immortals......

"Anyway, let's start practicing as soon as possible!" she urged.

"I wanted to talk to you first......" The immortal smacked his lips regretfully, his body couldn't get out of the wet bone forest, and it was rare to have the opportunity to chat with people.

"Then let's start cultivating immortal arts first. ”

It thought for a moment, and split a small slug from its body.

"Then, I'll guide you to cultivate immortal arts!" Split said, "First of all, before you cultivate, I'll give you a complete introduction to the knowledge of immortal arts, so be sure to listen carefully......

Of course, the concept of immortal arts, Haruno Sakura had already understood before coming to the Wet Bone Forest.

However, she still made a good student posture of listening attentively.

The so-called immortal art is a completely different system from ordinary chakra ninjutsu: the chakra consumed by ninjas when they use ninja illusion is made up of a mixture of spiritual energy and physical energy, while the immortal art consumes a fairy chakra - a high-level chakra formed by mixing ordinary chakra with natural energy.

As for natural energy, as the name suggests, it is the free energy that exists in the entire biosphere, in the whole living nature. In the world of Sakura Haruno's previous life, the so-called "natural energy" was probably the oil, coal, and other resources that supported the operation of the entire human society, but in the world of the Hokage, after the energy of the sun was absorbed by the biosphere, it seemed that it was more inclined to transform into this ethereal but ubiquitous natural energy......

Except that the chakra used is a little more advanced and powerful than the ordinary chakra, the immortal art is probably not much different from ordinary ninjutsu.

“…… Therefore, the main point of the cultivation of immortal art is to learn to combine ordinary chakra with natural energy, and to achieve this, it is necessary to harmonize and harmoniously integrate natural energy with physical energy and spiritual energy. ”

The little slug, which is only about ten meters long, explained.

"Doesn't sound too difficult. The girl thought for a moment and smiled.

"Don't be careless!Immortal cultivation is very dangerous!" the little slug shook the tentacles on his head, "Although Haruno Sakura-sama, you have a very strong control over ordinary chakras, but when you encounter a new immortal chakra, your previous experience is not good...... Anyway, has Sakura-sama ever tried to control the ratio of physical energy to spiritual energy in the chakra?"

"Of course there is!" the girl nodded naturally, "When using medical ninjutsu, it is usually necessary to carry out a change in the nature of the chakra, and at this time, it is possible to increase the degree of the change in the nature of the yang escape by fusing about 70% of the physical energy and 30% of the spiritual energy into the chakra." ”

"Or when using illusion, it is usually necessary to use a chakra with a mixture of physical and spiritual power in a ratio of 28 kai, and the spirit plays a vital role in illusion, so the chakra with a high proportion of spiritual power has the best hallucinogenic effect. If you are in the case of water escape, the chakra of five or five will be more suitable, but some special ninjutsu will be different. ”

"In short, controlling the ratio of two energies is just a basic operation for a ninja like me who is used to surprise operations. So I think the Immortal Chakra shouldn't be too difficult for me. ”

The slug laughed.

"It's good to have self-confidence, but, Sakura-sama, the cultivation of immortal arts is as simple as you imagined! Both the body and spirit come from yourself, so it is easy to operate. But the natural energy that immortal magic needs to absorb comes from the nature of the outside world, and it is not so easy to control!"

It glanced at Sakura Haruno, and continued, "Moreover, before controlling the natural energy, the first thing we need to do is to learn to sense the natural energy first!"

"So, how do you get here?" Sakura asked.

Although natural energy is everywhere, it is not perceptible to human beings, just as human beings breathe all the time, but no one can perceive the nitrogen that occupies nearly eighty percent of the volume in the air...... In fact, after Sakura Haruno learned about the existence of senjutsu, she also studied whether she could sense natural energy on her own, and last year in the land of snow, she secretly trained for a month, but the result was nothing but the northwest wind to drink to her heart's content.

"Without guidance, with the quality of human beings, it will take about a hundred years to perceive the energy of nature. The word "just" is used quite well, "hmm...... One hundred years may be too long for you humans. However, the three major immortal cultivation holy places have their own cultivation methods, which can shorten the cultivation time to less than a few days! The toads use toad oil to help absorb natural energy, and the spirit of the snake clan is mysterious and secret, as for me——"

"My deity no longer absorbs natural energy all the time, and I'm very familiar with it......" The little slug smiled mysteriously, "So if you want to learn the magic quickly, I have a more direct and effective method than toad oil—"

"Merge with me!"

“…… What?!"

Sakura Haruno was stunned for a moment.

"Together, combined?"

The little slug nodded: "Well, fit." ...... to be exact"

"I'm the one who eats you. ”

[I originally wanted to send the amount of two chapters together, but I didn't expect it to be too late, and my spirit was a little bad, and I couldn't write a thousand words, and today (28th) is only this one]
