"You want to learn immortal arts?" The little slug looked at Wu Di in surprise, with incredible voice. It obviously did not expect Wu Di to say so.

"Well, yes, please teach me Lord Slug!" Wu Di nodded with a serious expression, and he was just a joke.

"Hinata, the practice of immortal arts is even stricter than you think. Even Princess Tsunade did not practice!" said the little slug cautiously.

"Sir Slug, I'm very clear about it. I want to practice immortal arts. Please teach me!" Wu Di insisted very much. His immortal body needs to be activated in any of the three holy places. Now he has established a psychic contract in the wet bone forest. No matter what, the wet bone forest is the most important place to go.

"Hinata, are you serious?" The little slug couldn't recognize it and repeatedly confirmed it.

"Yeah, serious." Wu Di nodded.

"I understand." The little slug continued: "If it is too slow to hike directly to the wet bone forest, a lot of time will be wasted on the road. Wait for me to reverse the spiritualism in the wet bone forest!"

Suddenly.

As soon as the little slug finished speaking, Wu Di's figure disappeared, and the next moment it appeared in a completely different place, surrounded by green plants and full of vitality.

Surrounded by emerald green plants, a towering behemoth like a mountain range was not far away in front of Wu Di.

"Master Slug!"

Wu Di looked at the slug fairy's original figure in front of him, and couldn't help but sigh. No wonder no one has ever used spiritual techniques to summon the slug fairy's original body, and he can only summon part of it. It's really too huge.

"Hyuta, I still want to explain to you that what you want to learn is immortal art, not ninjutsu. Compared with ninjutsu that utilizes energy in the body, immortal art is to absorb external energy and use it." said the slug fairy.

"Yes." Wu Di nodded and listened carefully.

"I think you should know that ninjutsu is a magic trick to use the spiritual energy and chakra in your body!" The slug fairy continued.

"Yes, I know." Wu Di nodded again and added silently in his heart, that was an ordinary ninja, he was different, he was hanging on the wall, he couldn't refine chakra, his chakra was obtained by adding points.

Wu Di can be said to be an alien in the Naruto world!

After all, it comes from another world.

Wu Di's attributes are very simple, and they are directly divided into three types: spiritual power, physical power and chakra power.

They do not interfere with each other.

Compared to ordinary ninjas who extract chakra from their spiritual and physical strength, Wu Di seems to have an independent blue bar.

"Immortal art is a magic that uses the chakra you cultivate yourself, plus the natural energy absorbed from the outside, to continue practicing, to create newer and stronger chakra, and to use it!" said the slug fairy seriously.

"I understand." Wu Di nodded. He did understand this theory, but he was still a little confused about how to do it.

"The spiritual energy and physical energy inside the body, as well as the natural energy outside, combine these three energy, practice chakra and launch magic is immortal art! Therefore, immortal art can greatly improve ninjutsu, illusion, and even physical art!" The slug immortal explained again.

"Let me think about it." Wu Di rubbed his head. His chakra itself was not produced by physical energy and mental energy. So how can he absorb natural energy? The preconditions are wrong. Can he continue to proceed later?

"Hinata, it is difficult to obtain natural energy, and it is easy to say it is easy to say it. Simply put, it is necessary to integrate with nature, that's fine." The slug fairy said an extremely unpredictable sentence.

"Uh..." Wu Di took a deep breath and was a little silent. He seemed to realize that this was the most difficult problem he had encountered since he got Tsunade bag to learn medical ninjutsu.

"hhhhh has announced the method of practicing immortal arts!"

"I remember the big guys who had been making excuses before, go and practice with the anchor!"

"I'm a little confused. Why do you need to learn immortal arts? Isn't it okay to learn ninjutsu from the anchor? That's why you have surreal power in modern times."

"Don't ask, the anchor doesn't teach you!"

"Stop talking, what's the point? Why don't you ask the anchor how to travel through time? Why don't you explore the system? Besides, the anchor himself can't practice, everything depends on the system."

"That's just that you are not hanging walls. As chosen people, you'll be done!"

"…"

Just as Wu Di was silently thinking about how to fuse natural energy, the barrage began to argue with each other.

The reason is very simple.

As early as when Wu Di had just traveled to the Naruto world, someone asked why he didn't teach everyone how to learn ninjutsu.

Wu Di never paid attention to it.

How to teach?

Why don't you tell me how to build planes here...

"Don't care about him so many! Just try!" Wu Di's mood suddenly became clear. He even had an immortal body, so he would not be unable to activate the immortal body, which was not in line with the logic of the system.

Take a step back.

Even if you have not learned the magic of immortals, you will have no harm in obtaining this extremely vigorous immortal body.

"Let me think about it..."

Wu Di slowly closed his eyes and silently calculated a set of formulas in his heart, which originally belonged to the ninja world.

Body energy, mental energy = chakra.

Chakra Natural Energy = Fairy Chakra.

Body energy, spiritual energy, natural energy, = immortal chakra.

For normal ninjas, this is a very simple mathematical substitution formula, but it makes Wu Di suddenly realize something.

1. Chakra Natural Energy = Fairy Chakra.

2. Body energy, spiritual energy, natural energy, = immortal chakra.

There are two ways to obtain chakra in my own way.

Both formulas must be balanced!

That is to say.

Body energy, mental energy, chakra 2 times the natural energy = 2 times the immortal arts, chakra.

"I see!"

Wu Di suddenly opened his eyes, and a confident light flashed in his eyes. He immediately understood something very comfortable. He should be able to absorb twice as much natural energy as a normal ninja, and to produce twice as much magic chakra.

"Sir slug, how do you absorb natural energy?"
