Sasuke stood on the back of the giant eagle and was taken down the mountain, and the giant eagle circled and swooped in the air, as if to test Sasuke, but Sasuke stood on its back unaffected until the giant eagle landed on a lake, Sasuke slipped off its back, and asked, "I don't know your name yet!"

"My name is Ying Lie, there are several eagles of the same level as me, we are all war eagles, you can summon us in future battles, we are good at different things, you will know this later, now I will teach you immortal arts, but the immortal arts of our eagle clan are not easy to learn, I hope you are well prepared." Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info" said the Giant Eagle.

"My name is Sasuke Uchiha, please take care of me in the future!" Sasuke greeted in a friendly manner.

"Immortal art is a form of using natural energy, so first you need to feel the energy in nature, and then absorb this energy for your own use!" Immortal arts can be integrated into your chakra, combined with your chakra use, which can not only save your own chakra, but also increase the power of ninjutsu, but the cultivation of immortal art is not simple, some psychic beasts use some things to increase the ninja's perception of natural energy, but our eagle clan does not have this kind of thing. ”

"No?" Sasuke was stunned, how could I cultivate without this kind of thing, wouldn't it be a waste of feelings if I just felt that I was here?

"Yes, no, but we call it Eagle's Nest Mountain here, the best place among all psychic beasts, natural energy is the most abundant, as long as you can feel it quietly, you can easily feel it, if you don't believe it, you can try, you will live by the lake during this period of cultivation, there are other eagles will come to see you, after all, cultivating immortal arts is also risky, it is easy to be assimilated by natural energy at the beginning, and the body will change, once there is a problem, it will pull you back. After saying that, Eagle Lie flew away with a wing, but as soon as it flapped its wings, a strong wind immediately rolled around it.

Sasuke covered his hair with his hand, and then stood by the lake in a daze, watching the water churn, but soon a kitty came behind him, the same one that had given him the first message.

"Yo, I didn't expect you to succeed so quickly, let me introduce, I'm a swift eagle, my name is Eagle Hurry!"

"I'm Sasuke Uchiha, please take care of me, but what should I do with the cultivation of senjutsu?

"Yes, it's the feeling of sitting here and meditating, the key is to meditate, the natural energy here in our Eagle's Nest Mountain is the most abundant, as long as you can calm down, you can feel it, it's very simple!" Sasuke sat down in disbelief and began to feel the natural energy around him.

Natural energy is those elements in the air, the way to collect these elements for their own use is called immortality, this is a form discovered by psychic beasts, and it is also a way native to this world, the use of immortal mixed chakra is more powerful, more saving chakra, and at the same time, if conditions permit, it can be used forever, the key lies in the mastery of natural energy.

If you want to communicate with natural energy, you need to integrate yourself, but you can't lose yourself yet, otherwise there will be unknown changes after being transformed by natural energy, Naruto because of the relationship between using toad oil, so once he is transformed by natural energy, he will become a toad, but Sasuke is useless, he doesn't know what will happen. But it's not easy to meditate, Sasuke is a person who likes to calculate, and now it's a little difficult to let him meditate, sitting cross-legged by the lake, his mind is always active, and he himself is a little uncontrollable.

Is it easier for simple people to learn immortal arts? Sasuke sat for a long time and was a little helpless, it was really not very easy to meditate on his own, and it seemed that it was difficult to stop thinking!

"Oh, I didn't expect you to be able to calm down!" said Eagle anxiously.

"Yes, I didn't expect that there is no problem with hard cultivation or anything, my biggest problem is that I can't calm down, this is really not a shortcoming, but it has become an obstacle in the cultivation of immortal arts, what an accident!" Sasuke laughed as he spoke, a little self-deprecating, it seems that he is really suitable to be an accountant, and he likes calculations so much.

However, Sasuke thought for a moment and asked again, "I heard that the toads in Miaomu Mountain can use toad oil to help cultivate immortal arts, why doesn't there be anything in Eagle's Nest Mountain to assist in cultivation?"

"Oh, so you know which toads! But although their toad oil is very convenient, it also has disadvantages, the most obvious is that it is easy to become a toad, haha. "Takaku seems to be very happy, Sasuke is confused, Naruto's immortal mode is indeed a bit like a toad, but is there anything wrong with this?

"Hmph, don't compare them to us, Miaomu Mountain, Longdi Cave, Wet Bone Forest and other places I think you have heard of, these guys used to be just our food, and their methods are like that!"

"Huh, food?" Sasuke didn't understand, they lived in different spaces, how could there be food? Of course, in nature, eagles have no natural predators, they eat a lot of other animals.

"Then I'll tell you from the beginning, when humans didn't appear at the beginning, we all lived in your world, but suddenly there were some changes, and our places of residence have become independent spaces, and no one knows the specific reason, but our place of residence and your world have a passage, but this passage is very secret, and we found out after a long time, and when we went out, we found that there were human beings, and we were happy to live independently, until the last ninja appeared, and there was a psychic beast。 ”

"Oh, I see. Sasuke was shocked, he had always thought that there was something wrong with this world, and now it seemed that the problem was even bigger. "So, where did the retreat technique you use now come from?"

"Well, it's good to ask, we are all born to use the escape technique, but now you are estimated to be unable to do it, the eagle is born to use the wind to escape, the toad is born to use the water escape, these escape techniques we are born with, the battle between animals is not a simple hand-to-hand combat, we used to use ninjutsu, of course, this statement was also brought by the ninjas later. ”

In this way, Otsuki Kaguya is not the ancestor of ninjas, at least the animals will use it, and if they were not inexplicably made to an independent space at that time, then humans can learn from them. (To be continued.) )
