Tsunade paused, and then said, "The three immortals in the three holy lands have all been through thousands of years and have used natural energy to practice to reach their current level... But the difference is that the Big Toad Immortal in Miaomu Mountain and the White Snake Immortal in Dragon Earth Cave have created methods that allow humans to absorb and use natural energy like them."

"Where is the big slug fairy?" Uesugi Tsubaki asked.

Tsunade shook her head: "The big slug immortal has not created a method suitable for inheritors to practice and use natural energy."

"This..." Uesugi Tetsu was confused when he heard it.

So what is going on?

Can't the three great immortals practice the methods they themselves be taught directly to humans? Or...

In short, Uesugi Tsuna's words cannot understand. Even if the three immortals practice and use natural energy, humans cannot use it directly. The wet bone forest, like the other two holy places, can create a method that the inheritor can use.

With the ability of the big slug fairy, can't it be created?

After all, big toads and big white snakes are good, why can’t big slugs?

After asking about his doubts, Uesugi Tetsune heard Tsunade say: "The three great immortals have different directions of practice, and their own methods of using natural energy are also different. The Big Toad Immortal in Miaomu Mountain uses a method of applying tomato oil to the practitioners to let them perceive the natural energy between heaven and earth, thereby achieving the purpose of practicing natural energy..."

"The white snake immortal in the Dragon Earth Cave used his sharp teeth to inject his own natural energy into the body of the practitioner to help him absorb natural energy..."

"However, natural energy is beyond the reach of human beings. When practicing natural energy, it is very easy to be assimilated by natural energy, and all the vitality of the body is returned to nature."

After hearing this, Uesugi nodded secretly. He couldn't remember the Dragon Di Cave clearly. However, the practitioners of Miaomu Mountain turned into toads if they were not careful.

Immediately afterwards, Tsunade said: "As for why the Big Slug Immortal has not created a method that allows practitioners to practice natural energy, I don't know much, but..."

"But what?" Uesugi Tsuki felt that there might be some turning point in it.

Tsunade said slowly: "However, there was a person who successfully obtained natural energy through the original practice methods of the three great immortals and cultivated into the immortal mode."

Uesugi Tsuki couldn't help but be stunned: "Who?!"

He had a vague guess in his heart, but he was not so sure.

After all, it is really surprising that a human being can follow the practice method that is not suitable for humans to practice into an immortal mode.

Tsunade looked at Uesugi and said seriously: "My grandpa, first-generation Hokage, Chiju Hashirama!"

Uesugi Tsuki's eyes widened in an instant.

I guess it was him!

"The first generation...how did he practice? Isn't it said that the original practice methods of the three great immortals are not suitable for human practice?" Uesugi Takashi asked.

Tsunade shook her head: "I don't know much about this, but the first generation's physique is special, and maybe there is any way to do it. Unfortunately, he didn't tell me."

When Uesugi nodded secretly when he heard this.

My heart says that the first generation's purpose is of course special and has extremely strong vitality. This special physique can certainly avoid some risks when practicing natural energy, such as being assimilated by natural energy.

Of course, it is not clear whether the dead energy he possesses is the same as the vitality of the first generation, and has the same special "treatment" in practicing natural energy.

But Uesugi still wants to try it.

"I want to give it a try." Uesugi Tetsu said seriously.

"No." Tsunade shook her head again, "It's too dangerous! Do you know that if you follow the original method of natural energy practice, you will definitely be assimilated by natural energy!"

"But teacher, I have death energy in my body. What if I am also a special one? Besides, the Big Slug Immortal also said that my death energy needs natural energy to control. Then when I practice natural energy, it may be different from ordinary people." Uesugi Takashi was still unwilling to give up.

Tsunade heard this and pondered for a while, then refused: "No, no, this is too dangerous, if you are not careful..."

"Teacher! It's okay to try it. Just watch it. If it doesn't work, just knock me out immediately?" Uesugi Tsuki recalled that when Naruto was practicing natural energy, he was about to transform into a frog, so he used this method to block the absorption of natural energy.

Of course, that was created by the Great Toad Immortal of Miaomu Mountain and may be effective under the method suitable for humans to practice natural energy.

But now, if we follow the original non-human practice method, Uesugi Tetsu is really unsure.

But let's convince Tsunade first.

He himself had a faint feeling that there would be no danger in practicing the natural energy, and even if he was assimilated, he would not die anyway.

Tsunade sighed and then said, "I'll take you to see the Big Slug Fairy first. What's the result? It's up to her to decide. If she is willing to teach you, then...you can try it."

Uesugi Tsuna nodded quickly and followed Tsunade to the depths of the wet bone forest.

"Teacher, the first generation... Does Master Hashima's immortal mode use the practice method of the big slug immortal?" Uesugi Tetsu followed Tsunade, walking along, and asked.

He felt that the immortal patterns of Miaomu Mountain and Longdi Cave seemed not suitable for the first generation.

Moreover, if the first generation wanted to practice as the inheritor of Miaomu Mountain or Longdi Cave, they could just use the methods they created that are suitable for human practice.

There is no need to use the immortals’ own non-human methods to practice.

From this we infer that the practice method of the first generation should be the practice method of the Great Slug Immortal.

"That's right, you're not stupid." Tsunade glanced at Uesugi Tetsuya with interest.

Uesugi Tsuki curled his lips, what is this?

Am I stupid?

cut.

"It's all the teachers who are good at guiding them, haha..." Uesugi Tsuki looked pleased.

Thanks to Kado's words and deeds.

While talking, Uesugi Toru and Tsunade saw the huge slug again.

"Big Slug Fairy." Uesugi Tetsu bowed respectfully.

"It's Kokimura. It's been a long time since I saw you, your strength has improved again." The voice of the slug fairy slowly came out, very crisp and spiritual.

Uesugi:???

"Slug Fairy, my surname is Uesugi..." Uesugi Tsuki sighed inwardly and then said.

What's this all about!

"Oh, so that's it, I've recorded it, Kimura." The slug fairy said.

Uesugi:...
