The genius of Naruto is a bit ordinary.

"I am... invincible?"

Xia Li felt his current strength, and then looked at Kaguya Otsutsuki who was lying on the ground and unable to get up, and slowly walked over.

"Why... are you able to use the power of the Rinnegan?" Kaguya Otsutsuki asked with surprise and despair.

"Because, when you are strong enough, no matter what kind of ability it is, there are rules behind it, and I just mastered the rules and used them." Xia Li replied.

Kaguya Otsutsuki was stunned and didn't reply, because Xia Li said it simply, but who could really do such a thing?

Although this mode seems to be very similar to the copying of the Sharingan, there is an essential difference between them. That is, the copying of the Sharingan only copies the opponent's chakra flow and hand seal method, thereby using the same ability.

But the mastery that Xia Li mentioned means mastering the ability in essence. There is no need to copy it, and even the way of using it can be different. He just can use it.

Just like the Sharingan, even if the Mangekyō Sharingan reaches the highest level, it is impossible to copy the power of the Rinnegan, but Xia Li is able to master the rules of application by watching and use it.

Xia Li also saw that Kaguya Otsutsuki was still very confused. He was not in a hurry at this time, so he began to explain.

"Otsutsuki Kaguya, you should know the magic that your son Otsutsuki Hagoromo has learned, right?" Xia Li asked.

Kaguya Otsutsuki nodded, a little puzzled. Could this be related to immortal arts? Is that kind of power really that strong?

Xia Li nodded. It was a lot easier since he didn't need to start by explaining what immortal arts and sage mode were.

"The Sage Mode of the Six Paths Sage is a mixture of chakra and natural energy produced by his own Otsutsuki bloodline. It doesn't actually have any special abilities, but because the quality of the Otsutsuki clan's chakra is too high, his Sage Mode is unexpectedly powerful." Xia Li said.

"What does this have to do with your ability to use Shinra Tensei?" Kaguya Otsutsuki was a little confused.

"Don't worry. In fact, the normal Sage Mode should have special abilities, and such abilities are often the characteristics of some races. For example, Kaguya Otsutsuki, do you know that there is an ant called leaf-cutter ants?" Xia Li asked.

Before Kaguya Otsutsuki could answer, Xia Li shook his head and said, "Forget it. You probably don't even know the abilities of humans, so how could you possibly know about ants?"

Then, Xia Li began to say, "This is an ant that can lift more than fifty times its own weight."

"So what? Even if an ant lifts fifty times its own weight, it is only a tiny force." Kaguya Otsutsuki was puzzled again. With the weight of an ant, fifty times is probably only the weight of a leaf, right?

"What if I tell you that the Sage Mode I formed through the characteristics of the leaf-cutter ants is based on my own abilities? I forgot to tell you that the leaf-cutter ants I just mentioned can lift fifty times their own weight without the involvement of any external force, chakra, natural energy, nothing at all." Xia Li smiled.

At this time, Kaguya Otsutsuki's pupils shrank. She roughly understood what Xia Li meant. That is to say, after entering this Sage Mode, she would be able to use her original strength as a basis and then exert several times the power?

And after adding chakra or natural energy, this power is estimated to be... far more than fifty times!

"In addition, the leaf-cutter ant is not actually the strongest in this regard." Xia Li said again. He was just giving an example. Some creatures can lift nearly a thousand times their own weight without the blessing of chakra and natural energy. They are terrifyingly strong.

Kaguya Otsutsuki was silent for a while, and then she understood what Xia Li meant, and asked again, "So, is there a special Sage Mode that allows the user to quickly master abilities?"

Xia Li nodded, then smiled and asked again, "Do you know what the biggest difference between humans and animals is before they master chakra or natural energy?"

Kaguya Ōtsutsuki did not answer, she was thinking.

Xia Li did not give Kaguya Otsutsuki too much time to think, and said, "It is wisdom, or thinking."

Kaguya Otsutsuki seemed to understand something at this moment and looked at Xia Li.

"The individual force of humans in nature is definitely not strong, but humans can rely on their own strength to become the most core leaders in this world. It is based on wisdom. Humans use wisdom to create tools, and after having chakra, they also created various ninjutsu." Xia Li said, looking at Kaguya Otsutsuki and smiled.

"Among them, those ninjutsu that gave you a headache, such as the Eight Gates Ninjutsu and Flying Thunder God, were not created by me."

Kaguya Otsutsuki was silent. At this moment, she couldn't help but think, if she could learn these things and learn how to fight, would the outcome this time be different?

However, Kaguya Otsutsuki looked at Xia Li and sighed inwardly, always feeling... that it would still be a bit difficult with this guy around.

"So, the ability to see through everything is the magic of human beings. It is not as powerful as the magic of leaf-cutter ants, and it is not as fast as the magic of cheetahs, but it can enable the user to have enough thinking to understand everything, and then create everything." Xia Li said with a sigh.

"So, I just remembered the Shinra Tensei that someone had used before, and then I tried to understand it, and then I used it successfully. It's that simple."

At this moment, Xia Li also sighed that human immortal arts were indeed the most suitable path for human beings from the very beginning.

After he learned about the various types of Sage Mode, he always had an idea, that is, since other creatures have corresponding specialties in Sage Mode, then do humans have them too?

And now, as Xia Li's life was slipping away, he had finally succeeded in mastering the immortal arts of man.

Unfortunately, there is a paradox here.

That is, if you want to master the immortal arts of mankind, you need to understand the origin of everything, but understanding the origin of everything is almost impossible. Even Xia Li achieved this through fusion.

Therefore, if you want to directly learn the immortal arts of humans... at least Xia Li thinks the possibility is very small, even if you want to teach it to others, it is not possible.

Xia Li thought about it, then smiled. Perhaps he was wrong.

In fact, human immortal arts may not be that difficult. It’s just that human immortal arts at the beginning may not have the ability that Xia Li has now after he understands the origin.

Because human immortal arts have another specialty, and that is learning.

Therefore, Xia Li roughly understood that what he should have learned from the very beginning was the human immortal art, and then use the learning ability of the human immortal art to continuously expand his knowledge and seek all the origins, so that he could also step into the human immortal art that he has achieved now, right?

And then set foot in the realm of the Origin Immortal? Probably.

Xia Li couldn't be sure because he had never walked this path, so even if he felt there was this possibility, he couldn't be sure.

However, this might be the most normal path. Xia Li also felt that if he had mastered the art of human immortality when he was a child, his path would have been much smoother.

Unfortunately, it was impossible for anyone to teach Xia Li at that time to master the magic of human beings.

"Yes...that's how it is." A hint of realization appeared in Kaguya Otsutsuki's white eyes. She seemed to have understood something at this moment, but she seemed even more confused.

However, Kaguya Otsutsuki felt that even if she understood, it was too late. After she came to this world, she ate the fruit of the sacred tree. No one had ever been able to be her teacher, and no one dared to guide Kaguya Otsutsuki.

Perhaps, this is the culprit why she was sealed by her own son before, and now she is about to be sealed again after finally being "resurrected"?

"Shintogawa Xia Li, are you going to seal me next?" asked Otsutsuki Kaguya. She no longer had any thoughts of resisting at this point. She had originally wanted to struggle, but through this conversation, she felt that she probably really could not be Xia Li's opponent.

Xia Li had seen all of his abilities, so that meant...

Xia Li was able to use all of Otsutsuki Kaguya's abilities to kill Haigoku, Ame-no-Mikado, etc. In this situation, Otsutsuki Kaguya really didn't think she had any chance.

"Have you given up?" Xia Li looked at Otsutsuki Kaguya and sighed. He had originally wanted to wait for Otsutsuki Kaguya to fully recover so that he could fight with him now, but unfortunately Otsutsuki Kaguya gave up directly after listening to him.

However, it doesn't matter. Just as Kaguya Otsutsuki thought, he can now use all the opponent's abilities. He can even use all the abilities he has seen in his memory, whether it is bloodline limit or bloodline elimination.

Xia Li had already roughly understood before that being able to use the Kekkei Network does not mean that one can use the Kekkei Limit. It only means that if one can use the Kekkei Network, it will be very easy to figure out the corresponding Kekkei Limit.

Because the proportions of chakras required for fusion are different, the proportions required for the bloodline to gather the seven kinds of chakras cannot be the same as the proportions required for various bloodline limits and bloodline eliminations.

Because of this, theoretically speaking, there may be more types of bloodline limits than just the mixture of two types of chakras, and the effects of mixing chakras in different proportions may be different.

However, Xia Li now does not have much time to sort out everything he has seen. After he finishes everything, he will return to his original position and then make everything he has now perfect!

For example, try to find out bloodline elimination other than Dust Release, or the ability of the fusion of four or five attributes at a higher level, etc...

Of course, one thing is certain, that is, Xia Li will probably return to the boring state of having no opponents before.

Moreover, what is a little different is that before, Xia Li could still expect various people of the Six Paths level in the four wars to act as his opponents.

Facts have proved that Xia Li's idea was indeed correct. In this four-game war, he fought almost from the beginning to the end, from the shadows of the various ninja villages at the beginning, to the Impure World Madara, Six Paths Obito, Six Paths Madara, and finally Otsutsuki Kaguya...

Even Xia Li still feels a sense of complete clarity.

But when he thought about the road ahead, he felt a little empty, because this time there was nothing for him to look forward to.

Are they the Otsutsuki who are of the same clan as Otsutsuki Kaguya?

Xia Li really doesn’t think that their strength will be stronger than Six Paths Madara. Maybe there are a few, but... can they reach Xia Li’s current level if they surpass Six Paths Madara?

So, the road ahead might be... a little boring.

However, Xia Li still wants to become stronger, even though he can no longer see the way to become stronger in the future, he will not give up.

Does becoming stronger require a reason? Xia Li thinks that it does not require one, because becoming stronger is a reason in itself.

Xia Li slowly came in front of Kaguya Otsutsuki, and put his hand on Kaguya Otsutsuki's belly in front of Kaguya Otsutsuki's eyes.

The next moment, Xia Li and Kaguya Otsutsuki have returned to the world of ninja, and what Xia Li is going to do next is related to this world.

Then, endless chakra began to flow from Kaguya Otsutsuki's belly towards Xia Li.

"I... that's mine..." At this moment, Kaguya Otsutsuki's eyes were red, like a child whose favorite toy was taken away. She wanted to resist, but...

In the end, Kaguya Otsutsuki looked at Xia Li and sighed, saying that children cannot resist in front of adults.

Xia Li ignored Kaguya Otsutsuki and continued to absorb her chakra. At this time, Kaguya Otsutsuki possessed all the chakra in the world.

Even if there are some omissions, it’s not 100% but it’s 99.99…%, so it doesn’t matter.

Endless chakra rushed towards Xia Li like a whale as Xia Li absorbed it.

But even so, facing the amount of chakra in a world, it would still take Xia Li a long time to absorb it completely.

After a long time, Xia Li finally absorbed all the chakra from Kaguya Otsutsuki into his own body. At this time, the blood-red Samsara eye on Kaguya Otsutsuki's forehead had closed. It can be imagined that she could no longer open that eye.

At this time, Kaguya Otsutsuki also slowly lost consciousness and her body became emaciated. That was the image after losing all chakra. After all, chakra contains the body's energy!

At this moment, Xia Li felt the terrifying amount of chakra in his body... and couldn't help but mutter.

"No wonder Uchiha Madara was blown up. How could one person's capacity possibly bear the volume of an entire world?"

Xia Li did not include himself, because now he has already stepped into the final realm. Although he still feels very satisfied, he is not yet to the point of being overwhelmed.

If there were another world, perhaps he would not be able to bear it, but he would definitely be better than Uchiha Madara, because his level has the ability to quickly consume excess chakra.

Now, Xia Li also took a deep breath, and a trace of solemnity appeared in his eyes.

Next, it was what he had always wanted to accomplish, which was...

Convert all chakras into natural energy and then inject it back into this world!

Let this world return to its original state!
