Naruto: This Uchiha is a businessman.

Lu Lin also knew something about Yahiko's situation, but even if he transplanted the Uchiha clan's Sharingan or other Byakugan to Yahiko, the improvement to Yahiko would be too small. After all, he did not have the blood of the Uchiha or Hyuga clan.

The Sharingan, even if Kakashi only transplanted one, has become a unit of chakra measurement in the Naruto novels, not to mention Yahiko.

As for Nagato? He is a member of the Uzumaki clan, and his natural chakra capacity is higher than that of ordinary people, so he can afford it.

As for the Byakugan, Yahiko, who has no bloodline, can only use it as a means and there is no need for him to even think about awakening the Pure Eye.

The reason why Lu Lin can use it is because he has the blood of the Otsutsuki clan from outer space in his body. Although it is very weak now, Lu Lin can completely improve his blood to the level of the Otsutsuki family with his talent and hard work, and even reach the level of the Otsutsuki ancestors.

However, Lu Lin is not without a solution. We cannot use things from outside the sky, but we still have the things inside the ball. Lu Lin is still very optimistic about natural energy and sage mode, but there is no way to access them now.

but. . .

"If you want to improve your strength, there are ways."

Lu Lin said with a smile.

His words cheered up the depressed Yahiko, his eyes were shining. He could keep up with his companions. Who would really want to be left behind?

"Really, bro?"

Yahiko said excitedly, but soon waved his hand:

"Forget it, brother. I am just being pretentious. The method that can improve the strength of ordinary ninjas like us is definitely more complicated. You have helped me a lot, so I won't trouble you. Besides, my ideal has always been to make the ninja world peaceful."

But now that he has thought it through, how could Lu Lin let Yahiko refuse?

"It's okay. It's not a big deal. It just takes some time to find it."

Nagato also chimed in:

"Brother has said so, Yahiko, just give it a try."

"this..."

Being watched by everyone, Yahiko was too embarrassed to continue to refuse. After hesitating for a while, he slowly nodded:

"Well... well then, Brother Lu Lin, you just need to tell me what to do. As for the search, I will do it myself. I can't trouble you any more."

This is what I was waiting for. Lu Lin nodded with satisfaction:

“In fact, in the entire ninja world, there is only one kind of energy, called natural energy, which comes from the natural world.

The chakra energy we use now is a degraded form of natural energy."

Lu Lin's words left everyone present stunned. In their understanding, chakra has always been the only energy in the ninja world.

Even though the three members of the Akatsuki organization were disciples of Jiraiya, they had never heard Jiraiya say these things. After all, to Jiraiya, these three people did not belong to Konoha, so he had never told them some secrets. Of course, it is also possible that Jiraiya himself did not know much.

"A thousand years ago, a sacred tree appeared. It plundered a portion of the natural energy and converted it into chakra. So, logically speaking, the chakra we use now comes from that sacred tree."

"After that, three more animals appeared. They were the toad of Myoboku Mountain, the giant snake of Ryuchi Cave, and the slug of Wet Bone Forest. They also usurped the authority of some natural energy, allowing their entire species to easily use natural energy for cultivation."

"There is still a part that is still floating on the surface and has not been used by humans. Of course, if you want to use natural energy, unless you can go to the three major immortal places, which are the habitats of the three animals, and practice using the methods they provide, otherwise, you can't even absorb natural energy."

"Of course, the cultivation methods provided by those three places are not 100% successful, nor are they completely safe. There is still a certain chance that they will lead to the death of the practitioner."

After saying that, Lu Lin picked up a cup of tea on the table, tilted his head back and poured it all into his mouth. His throat was dry after saying so much at once.

Now he just needs to wait for everyone present to slowly digest what he just said.

After a long time, Yahiko swallowed with some difficulty:

"Brother Lu Lin, what you said..."

"I saw it in a document, but unfortunately the document was kept for too long, so it broke into pieces after I finished reading it."

It was just an excuse. Besides, Lu Lin knew everyone present very well. Their trust in him was no less than their trust in his family.

"What are those three holy places?"

Yahiko was a little confused as to what these three place names and three animals were that appeared out of nowhere.

"I'm sure you know your master, Jiraiya, well?"

Lu Lin said meaningfully.

"I... this..."

In the past, Yahiko would have nodded without hesitation, but now, it is hard to say. After all, he now knows how huge the gap is between countries and villages. As one of the three ninjas of Konoha, Jiraiya cannot be unaware of this. Therefore, when Yahiko thinks of Jiraiya now, he always feels that there are layers of fog around him.

It’s not that he was dissatisfied with Jiraiya’s actions. He saved them at that time and taught the three of them how to protect themselves. Yahiko was very grateful to Jiraiya.

But what he said was just a description of an event.

"The three ninjas of Konoha each have a summoning beast, and those summoning beasts come from the three holy places."

Lu Lin talked freely.

"But we haven't heard that any of them can use natural energy."

Nagato suddenly spoke.

"So, natural energy is not 100% usable. Among the three of them, only Jiraiya has enough talent to use natural energy."

"Of course, the three holy places will use natural energy, known as Sage Mode."

"Is that so?" Nagato nodded thoughtfully, but when he heard Lu Lin start talking again, he became focused again. For people like them who had no background, these things were extremely precious.

"The talent required for the cultivation of natural energy is actually different from the talent required for the cultivation of chakra. You need to explore and work hard on your own."

It is indeed difficult to explain talent, but what is certain is that what is needed to cultivate natural energy is somewhat different from the talent that people understand. Even if your chakra talent is good, it can only be of some help in cultivating natural energy.
