Chakra is hierarchical.From the lowest-level ordinary chakra, to the high-level attribute chakra with attributes, there are also the more advanced tailed beast chakra, immortal chakra.The level increase of Chakra can bring a leap forward in the strength of the ninja.Ordinary chakras have limited lethality, and the increase in their own strength is also limited, a typical example is the lower ninja, and the power of chakra is not as good as their own kunai shuriken weapons.However, when a ninja can use the attribute chakra, the various ninjutsu used not only have an attack power, but also an increase in attack range, and the power of the physical arts used is also greatly increased.A typical example is the Thunder Chakra activated cells that Sasuke often uses, various forms of Chidori.And the more advanced tailed beast Chakra, Chakra itself already has a strong erosion ability, converted into ninjutsu can easily kill and injure enemies, change the terrain in a large area, and act on their own body can also have invulnerable defense.The reason for this change is that the Tailed Beast Chakra is very pure and closer to the natural energy itself.And one level higher than the tailed beast chakra is the immortal chakra.This kind of chakra is directly mixed with natural energy in its own chakra, and directly uses natural energy as a means of attack, so it has achieved a more powerful killing ability.In the face of immortal chakra, if the reincarnation eye absorbs too much, it will also suffer from indigestion and eat up its own body.This speaks volumes about the fact that when the chakra level increases, the ability of the reincarnation eye to absorb chakra no longer has the priority of doing whatever it wants.However, this still does not close the loopholes created by the chakra system.And directly using natural energy for attack and defense, this is also an unrealistic thing, first of all, this does not completely restrain the ability of the reincarnation eye to absorb chakra, and the reincarnation eye can also absorb natural energy.Using natural energy directly will cause some trouble for it, but that's about it.Secondly, there is a limit to the amount of natural energy that exists in the environment.It's naturally no problem to absorb some refining immortal chakra a little, but if you want to rely on this to use some large-scale ninjutsu, it will take too long to read, and it will be easily interrupted by the enemy.And the most important reason is that natural energy contains some energy substances that are harmful to living things, and if you can't perfectly control its existence, you will become crazy if you continue to use natural energy to fight.A more typical example is those who have failed in immortal cultivation, and the Ten Tails who obviously have great abilities, but they fall into madness and can't even control themselves.Of course, you can also directly use Chakra, so that you will naturally not be restrained, but at present, in this ninja world, there is no system with stronger combat power than Chakra.If it is forcibly changed, it is likely that the problem of chakra loopholes has not been solved, but it will directly collapse its own combat logic.To sum up, if you want to make the reincarnation eye invalid, you need to raise your chakra level to a level that exceeds the priority of natural energy, so as to make up for the loopholes in the chakra itself.Naruto also had some thoughts on how to prioritize his chakra level over natural energy.His solution is to improve his personal traits in his chakra and strengthen his ability to control his chakra.And this inspiration comes from the Nine Lamas.If the chakra of the Nine Lamas is not restrained under normal circumstances, it will have an extremely strong corrosive ability, which will not only erode the enemy's body, but also erode the enemy's will, causing him to be upset and even lose his mind by the control of the killing intent.Imagine that if the chakras that Naruto unleashed himself were all infused with the sharp characteristics of the Wind Escape Cut, then the enemy would suck Naruto Chakra once he activated his ability to absorb chakra.Before he could use this chakra to fight back, he was directly blasted by the uncontrolled wind escape chakra from within his body.Or in his own chakra, he contains a strong personal will, and sets an emotional bomb, such as exaggerating emotions such as murderous intent, hatred, and madness as soon as he leaves his body.Once someone absorbs this chakra, it will cause their consciousness to be polluted.This ability will not cause the opponent to absorb the chakra ability to disappear, but it can effectively make the opponent dare not use this ability, then Naruto can open his ultimate move as he wants.And now, although there is a countermeasure to strengthen the body and use the ninjutsu to unleash the power of nature, this method of attacking the enemy in a circle will eventually lead to greater consumption.Therefore, it is still necessary to solve the problem at the root.However, although Naruto's direction is there, he doesn't know how to achieve it, so that his chakra has such a personal trait that can make the eyes of reincarnation fall into the sand.Naruto tested when he was sparring with Sasuke, even if he used his Wind Escape Chakra trait to the extreme, or if he had strong personal emotions in Chakra, he would still be easily absorbed by Sasuke with the Hungry Ghost Dao.It won't have any effect on Sasuke digesting his chakra at all.This proves that there is still a long way to go in order to improve one's chakra personal qualities to a level that rivals or even surpasses the energy of nature."
However, it can be used as a research topic in the future."
Thinking so, Naruto stopped dwelling on this issue and began to concentrate on studying how the ability to absorb chakra should be used.As the saying goes, if you can't beat it, join in.Since these enemies of the big barrel wood make them dare not use chakra to attack the enemy casually, then he can also learn this technique and null the opponent's ability to open ultimate.When the time comes, both sides will return to the same level for fighting.At this time, Naruto, who has completely mastered the use of the new ninjutsu, can have an advantage in battle.However, this can only be regarded as a way to treat the symptoms but not the root cause.If you want to solve this problem completely, you still need to work hard to increase the chakra level.Time passed day by day as Naruto studied and absorbed Chakra's ability.In the blink of an eye, three months have passed.It was at this time that Naruto finally mastered the ability to extract other people's chakras without the need for the eye of reincarnation.And in the process, Naruto also applied some methods to develop his physical potential, and his physical fitness increased significantly.Having mastered new abilities, his own combat power has increased significantly, which also makes Naruto extremely happy.But the joy didn't last long.He always felt as if he had forgotten something...
