"You want to learn immortal arts?" The little slug looked at Wu Di in surprise, there was disbelief in his voice, it obviously didn't expect Wu Di to say this.

"Well, yes, please teach me Lord Slug!" Wu Di nodded, his face was serious and serious, and he didn't mean to joke at all.

"Hinata, the cultivation of immortal arts, but it is even stricter than you imagined, even Princess Tsunade has not practiced!" The little slug said cautiously.

"Lord Slug, I think very clearly, I want to practice immortal arts, please teach me Lord Slug!" Wu Di insisted that his immortal body needed to be activated in any of the three holy places, and now that he had established a psychic contract with the slug-master of the Wet Bone Forest, no matter what, the Wet Bone Forest was the most important place to go.

"Hinata, are you serious?" The little slug didn't recognize it and repeated it again.

"Well, seriously." Wu Di nodded.

"I see." 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, you wait for me to reverse the psychic technique in the Wet Bone Forest!" ”

Suddenly.

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

Surrounded by verdant plants, a behemoth towering like a mountain range was not far in front of Wu Di's eyes.

"Lord Slug!"

Wu Di looked at the huge slug immortal deity in front of him, and couldn't help but sigh in his heart, no wonder no one has ever used spiritism to summon the slug immortal's body, and only a part of it can be summoned, it is really too huge.

"Hinata, I still have to explain to you, what you want to learn is immortal art, not ninjutsu, compared to ninjutsu that uses energy in the body, immortal art is to absorb external energy and use it." The slug immortal said.

"Hmm." Wu Di nodded and listened carefully.

"I think you should know, ninjutsu is a technique that uses the chakra that refines the spiritual energy and body energy in your body!" The slug immortal continued.

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

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

After all, it's from another world.

The attributes of Wu Di are very simple, and they are directly divided into three types, mental power, physical strength, and chakra power.

Do not interfere with each other.

Compared to ordinary ninjas refining chakra from mental power and physical strength, Wu Di is more like having an independent blue bar.

"Immortal art is a spell that combines the chakra cultivated by oneself and the natural energy absorbed from the outside to continue to cultivate, create newer and stronger chakra, and use it!" The slug immortal said seriously.

"I see." 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, fuse these three energies, and the chakra that is cultivated and launched is immortal magic! Therefore, immortal art can greatly improve ninjutsu, illusion, and even physical arts! The slug immortal explained again.

"Let me think about it." Wu Di rubbed his braincase, his chakra itself was not generated by physical energy and spiritual energy, so how to absorb natural energy, the preconditions were all wrong, can it continue later?

"Hinata, it's hard to say that it's hard to get natural energy, but it's easy to say that it's easy to say, it's just to be one with nature, and that's fine." The slug immortal said something extremely unpredictable.

"Forehead......" 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 the Tsunade bag to learn medical ninjutsu.

"hhhhhh has announced the method of cultivating immortal arts!"

"I remember that there were big guys who were coaxing before, go and practice with the anchor!"

"I'm a little confused, why do you want to learn immortal arts, isn't it okay to learn ninjutsu from the anchor, isn't that also a surreal power in modern times."

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

"Don't say it, what's the point of this, why don't you ask the anchor how to cross it, why don't you explore the system, besides, the anchor himself can't cultivate, everything depends on the system."

"Even if you are not hanging on the wall, as the chosen one, you will be reckless!"

「……」

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

The reason is simple.

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

Wu Di ignored it all the time.

How to teach?

Why don't you tell me to build a plane here......

"Whatever he does! Just give it a try! Wu Di's mood suddenly brightened, he even had an immortal body, and he would not be unable to activate the immortal body, which did not conform to the logic of the system.

Take 10,000 steps back.

Even if you don't learn immortal arts, then it won't hurt at all to get this immortal body with extremely vigorous vitality.

"Let me think about it......"

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

Physical Energy + Mental Energy = Chakra.

Chakra + Natural Energy = Immortal Chakra.

Physical Energy + Spiritual Energy + Natural Energy = Immortal Chakra.

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

1. Chakra + Natural Energy = Immortal Chakra.

2. Physical energy + mental energy + natural energy = fairy chakra.

There are two ways to get the Immortal Chakra.

Both formulas need to be balanced!

Other words.

Physical energy + mental energy + chakra + 2 times the natural energy = 2 times the fairy chakra.

"I see!"

Wu Di opened his eyes suddenly, his eyes flashed with confidence, and he suddenly understood a very comfortable thing, he should be able to absorb twice as much natural energy as a normal ninja, and he would be able to produce twice as many immortal chakras.

"Lord Slug, how do you absorb natural energy?"

After Wu Di figured it out, he immediately looked up at the mountain-like slug immortal, the excitement in his heart was already overflowing, once the immortal body was activated, then his strength would increase by leaps and bounds, reaching another level.
