As natural energy poured into the body, various toad characteristics appeared on the three children Neji, Hinata and Sasuke, either small bumps appeared on their skin, webbed flesh membranes between the fingers, or pupils turned into toad's horizontal pupils.

In this regard, Shenzao Immortal and Jirai were not surprised by this, because this is a process that must be experienced in practicing the immortal art of "Miaomushan".

Practicing immortal arts is actually a circular process of sensing the natural energy between heaven and earth, absorbing these natural energy, and then fusing these natural energy.

The advantage of practicing immortal arts in the three holy places is that practitioners can use various tricks to forcibly understand natural energy and absorb a certain amount of natural energy.

The toad oil applied to the arms of the three children by the Deep-School Immortal is the trick to practice the immortal arts of "Miaomushan".

Once the body is coated with toad oil, no matter who it is or the qualifications, you can sense the natural energy dispersed in the air within a certain period of time, and use toad oil to forcibly absorb part of the natural energy into the body to complete the first two steps of "perception" and "absorption" in the three major steps of practicing immortal arts.

However, what is really difficult to practice immortal arts is not the two steps of "perception" and "absorption", but the third, that is, the last step, "fusion".

Only by fusion of the natural energy absorbed into the body with its own chakra and digesting these natural energy can one truly master the magic.

After a while, the characteristics of toads on the three children sitting cross-legged beside the toad pool became more and more obvious.

Seeing this scene, Shenzuo Immortal shook his head to Jiraiya.

"Why!"

Jiraiya sighed.

The increasing characteristics of toads on the body indicate that none of the three children can merge into the natural energy that is inhaled into the body. Therefore, as the natural energy accumulates more and more in the body, the body tends to be more and more toads.

Although the failure of the first attempt does not mean that the three children have no talent to practice immortal arts at all, it can at least show that their talent in practicing immortal arts is far inferior to Naruto.

At this time, the Immortal Shenzuo quickly wiped off the toad oil from the arms of the three children, forcibly interrupting the process of absorbing natural energy by the three children. As the toad oil was wiped off, the characteristics of the toad characteristics of the three children gradually faded and slowly returned to normal.

Opening his eyes, Sasuke asked, "What's going on? Why can't you feel the natural energy suddenly?"

Neji and Hinata also opened their eyes and looked at the immortal Fukusaki and Jiraiya with confusion on their faces.

Shenzuo Xian said with some regret: "You have failed."

"Failed?!" After a moment of silence, Sasuke suddenly stood up: "I haven't felt it much yet, why did he suddenly fail?"

Neji also looked unwilling, and this inexplicable failure made him unacceptable.

Compared to the excited Sasuke and Neji, Hinata's mentality was much more stable, but there was still a hint of loss in her eyes, because deep down, she actually hoped that she could master the magic skills like Naruto. This was not how eager she was to have a common topic with Naruto.

It is obvious that the three children who are immersed in feeling natural energy are not aware of the changes in their bodies, so they are not aware of the danger coming at all.

If it weren't for the Shenzuo Immortals who were guarding each other and delayed for another five or six minutes, they might have turned into the toad statues beside the toad pool.

Looking at the expressions on the faces of the three children, Jiraiya understood their feelings and said, "You don't have to be too upset. Failed to try to do the first time, it does not mean that you have lost the opportunity to master immortal arts forever. In fact, it is a bit too much for you to try to practice immortal arts at this age."

When practicing immortal arts, the other conditions are not mentioned yet. The most basic point is to have a huge chakra.

If there is no huge chakra in the ninja's body, then there is no way to talk about the natural energy fusion and inhalation into the body, so a certain amount of chakra is the basic threshold for practicing immortal arts.

Although Neji, Hinata and Sasuke are both blood-successful ninjas of the Eyes and have talents far surpassing civilian ninjas, due to their age, the chakra in their bodies is limited, so when trying to fusion the natural energy inhaled into their bodies, they not only have no advantages compared to adults, but have obvious disadvantages.

Sasuke was dissatisfied: "Then why did Naruto succeed?"

Jiraiya explained: "Naruto's mother is the Uzumaki clan, so Naruto also has the bloodline of the Uzumaki clan. The Uzumaki clan is known for its huge chakra volume and amazing vitality, so in practicing immortal arts, that boy Naruto has an advantage over you."

Another point, Jiraiya didn't say it, that is, the stronger the ambition, the more unfavorable it is to practice immortal arts.

To put it bluntly, practicing immortal arts is to understand nature and use nature in a process. Naruto was confused when he was in the "Dragon Earth Cave", had no idea about immortal arts at all, and had no strong ambitions. He just followed his instinct to feel nature, so he happened to fit the mentality of practicing immortal arts and mastered immortal arts by chance.

The three children of Neji, Hinata and Sasuke understand the power of immortal arts and are more aware of the preciousness of the opportunity to enter the "Miaomu Mountain". Therefore, they have too strong ambitions to master immortal arts, and they are also worried about gains and losses, so they are not suitable for practicing immortal arts in terms of mentality.

The Immortal Mitsuru took over the conversation and said, "The qualifications for practicing immortal arts are not the same as those of your ninjas. Excellent ninjas may not be able to master immortal arts. Among the Narutoes of Konoha, only the first generation has fully mastered immortal arts. The second generation and third generation have not mastered immortal arts. The fourth generation has come into contact with them too late, and it is only a barely beginning before they die."

Sasuke said unwillingly: "Sage, can we try again?"

The Immortal of Deep Grass immediately shook his head: "No, now a lot of natural energy has accumulated in your body. If you continue to try again, the natural energy in your body will erode your body at the least, and at the worst, it will directly lose control, making you become these stone statues on the side."

When Neji thought of wasting the precious opportunity the teacher had won for him, he couldn't accept it, so he said, "Immortal, I'm willing to take the risk and give it another try!"

At this time, Jiraiya stood up: "I promised your teachers and family to bring you back safely."

The immortal Shenzuo smiled and said, "I am not considerate and should not use practicing immortal arts as a test. This way, you come to Miaomu Mountain to sign a psychic contract, so let's use the psychic contract as a test!"

After saying that, the immortal Mizusa summoned a large scroll, spread it in front of the three children, then pointed to Sasuke who was standing at the end, and said, "Come first!"
