(Dear book friends, in the new book period, roll and sell cute tickets, ask for collections, and ask for reading!) ）

After eating, it was not Li Chun who paid the bill, because he only had gold bricks in his hands.

After arranging Tsunade Ji to a hot spring hotel, Li Chuncai asked Shizune to go with him to find someone to exchange the gold bricks for money.

Then Li Chun and Shizun returned to the hot spring hotel with two boxes.

After all, Li Chun's hand is a standard gold brick scavenged from the Federal Reserve, weighing 10 kilograms, and according to the purchase price of the Hokage World, a gold brick is 60 million taels.

After pushing the box containing half of it, that is, 30 million taels, to Mute, Li Chun accepted Mute's teaching with peace of mind.

After listening to the theory of the Chakra extraction method, Li Chun asked again what he didn't understand, and repeated it several times until he had thoroughly understood the entire extraction method in theory, and then Li Chun stopped.

Then Li Chuncai closed his eyes and began to empty himself.

However, he was not prepared to follow the instructions above in the Chakra Extraction Method for the extraction of chakra.

In fact, all Li Chun wanted was the technique of mixing mental energy with physical energy.

As for why this is this, Li Chun has his own independent opinion.

As everyone knows, the word chakra in the Hokage world is derived from the sacred tree.

In fact, before the Six Dao Immortals, there was no concept of chakra.

But before the Six Dao Immortals, the Three Great Holy Lands had already mastered the use of natural energy, that is, immortal power.

Otherwise, it would be impossible for Toadmaru to give him a fairy power talisman paper that could heal any injuries before the Six Paths Immortals and Kaguyahime battled.

Therefore, Li Chun's inference is that after the Six Dao Immortals went to Miaomu Mountain, they learned how to absorb and use natural energy.

As for why Toad Pill had lived thousands of years on natural energy, while the Six Dao Immortals had burps at that time.

The answer is also simple, that is, Myoki Mountain has left a hand in the absorption of natural energy.

You must know that when Toad Maru found the two brothers of the Six Dao Immortals, the two brothers were already adults.

During this period, more than ten years were enough for the three holy places to develop a chakra version of the natural energy absorption method for the chakra used by Kaguya.

Don't forget, the three holy places have been monitoring Kaguyahime, and if you can't figure out what Chakra is going on for more than ten years, you won't be worthy of the title of Holy Land at all.

In addition, toad pills can predict the future, so it is not difficult to develop low-profile means of use.

But as Kaguyahime's son, will the Three Holy Lands fully believe in Otsuki Haji?

Impossible!

So the answer is obvious!

That is the immortal art learned by the Six Dao Immortals, which is actually the bankrupt version that Zilai also learned.

It is only in this bankrupt version that natural energy cannot be stored in the body for a long time to achieve the effect of nourishing the body and thus achieving immortality.

Otherwise, there is no reason why the Toad Pill can live for more than a thousand years, but the more powerful Six Dao Immortal Brothers have been dead for more than a thousand years.

Then the question arises, that is, before Kamayahime, what was the way that the three holy lands had mastered to truly absorb natural energy and condense immortal power?

Li Chun deduced this.

Then Li Chun was testing the most likely answer at the moment.

So what's the answer?

Quite simply, let natural energy replace physical energy.

As for why Li Chun analyzed this answer, it is not that Li Chun is guessing casually, but there is a certain basis.

First of all, the transcendent energy of the Hokage world is not only the natural energy full of life, but then the chakra created by extracting the earth's life force from the source of the Ten Tails.

And before the advent of chakra, there was only natural energy.

Then look at the precondition for the cultivation of immortal power, that is, the amount of chakra must be large.

Please note here that, according to Myogisan, only a person who is deep enough in chakra will be able to feel the presence of natural energy.

But here is a paradox that is very scary, what paradox?

In fact, what Chakra can sense is only Chakra breath, so how can the natural energy that does not belong to the same system as Chakra be sensed?

The answer lies in mental strength!

Yes, spiritual power is the key to being hidden by the three holy places.

Excluding some of the content added later, the condition for cultivating immortal power becomes that the spiritual power is strong enough to be able to feel the existence of natural energy.

Then, only with strong spiritual power can the natural energy be suppressed, and the fusion can be completed to control the natural energy.

There is no physical energy extracted from the cells, and the spiritual energy can be stored in the body in the form of immortal power after the fusion of spiritual energy and natural energy.

And because of the characteristics of natural energy, it can continuously nourish the body, so as to achieve longevity like a toad pill.

The most direct evidence of this is that the use of immortal power by the big barrel wood feather coat needs to absorb natural energy first, and when the toad pill is used, there is no process of absorbing natural energy at all.

In other words, the original immortal power cultivation method of Miaomu Mountain is definitely different from the cultivation method that was taught.

Then looking back, Kaguya didn't have chakra before, so there won't be a bankrupt version of the cultivation method.

In addition, the large barrel of wooden feather clothes also proved that temporary immortal power could not be immortal, and there was no energy other than natural energy in the Hokage world at that time.

Therefore, the cultivation method of immortal power is already about to come out.

Yes, before the appearance of Chakra, the natives of the Hokage World probably didn't think of a way to extract body energy.

After all, cultivating immortal power is for the sake of strength and immortality, which is contrary to extracting one's own cellular energy.

This is the key to Li Chun's courage to eliminate the energy of his body.

After the physical energy is excluded, there are only two kinds of spiritual energy and natural energy left.

As for why Li Chun had to use the energy mixture in the chakra extraction method to mix the spiritual energy with the natural energy that was about to be absorbed.

That's because this method is the most reliable, before the concept of chakra was proposed, whether it was Kaguya Ji or the two brothers of the Six Dao Immortals, their strength relied on their own talent to use power.

At that time, they didn't have the concept of mental energy and physical energy.

Therefore, Li Chun suspected that the Chakra extraction method was a method summed up by the Six Dao Immortals according to the cultivation of immortal power after excluding natural energy.

In other words, the extraction in the Chakra extraction method may have been created by the Six Dao Immortals, but the method of energy mixing was mostly from Miaomu Mountain.

Because of this, Li Chun chose this method to mix spiritual energy with natural energy.

As for obtaining the extraction method through Tsunadehime, it was planned by Li Chun in advance.

Instead of seeing Tsunade-hime, he decided to be Tsunade-hime.

Because the oldest chakra extraction method that Li Chun needed must have come from Senju or Uchiha to be the most reliable.
