There are many unsolved mysteries in the ninja world, and there are countless mysteries related to bloodline limits. Especially the Sharingan, after evolving to the level of Mangekyō, according to the different personal qualifications and differences in mentality, various strange Sharingan pupil techniques are formed, and it is indeed well-deserved to be named "Mangekyō".

Anger, sadness and hatred are the emotions that can most stimulate the power of the Sharingan. The unique eye techniques of the Mangekyō Sharingan that are activated under the influence of the mental fluctuations brought about by drastic changes are obviously strongly influenced by personal desires. Qualifications are one aspect, and personal experience is the cornerstone of the formation of unique eye techniques.

As for which one is stronger between the different eye techniques, that is a matter of opinion. As far as Mizuki knows, apart from Uchiha Obito's Kamui Space Transfer, which he has just witnessed, the only one he has personally experienced is Uchiha Itachi's Amaterasu, and he has also "tested fire with himself", so he knows the power of Amaterasu very well.

There is no doubt that Amaterasu's Black Flame can do a lot of damage, but its practicality is still a mystery. Although no one knows yet, there are indeed many ways to deal with Amaterasu. As the strongest physical attack, it is indeed impossible to solve the problem of being able to burn all matter, but that does not mean it cannot be restrained.

Although it is the strongest physical attack, it is not very effective against chakra. Natural energy, tailed beast chakra, attribute ninjutsu and even high-density chakra can directly isolate Amaterasu's black flame. As long as you dodge in time, there will not be much danger. Even if you fail to dodge, you can use ninjutsu or chakra to directly fight against it. Even if you are really hit, it doesn't matter. Just peel off the burned part as soon as possible. Kankuro was hit by Amaterasu, but he was unharmed after taking off his armor. The Raikage just abandoned the arm that was burned by Amaterasu, and it was fine. Not to mention other orthodox means such as the Fire Sealing Seal and the strongest life-saving illusion - Izanami.

So, to be precise, Amaterasu is indeed very strong, but as long as you deal with it properly, there is still a great chance of avoiding it.

Another very practical Mangekyō Sharingan technique is Uchiha Obito's Kamui. Being able to use space-time ninjutsu is already strong enough, but he also has a Kamui space of his own, which is amazing.

Especially this Kamui Space, there is something that Mizuki is concerned about. Logically speaking, Uchiha Obito originally had a set of left and right eyes, and there should only be one Kamui Space. Although the corresponding abilities of the left and right eyes are different, their foundations should be exactly the same.

A long time ago, Mizuki had an idea. If the above speculation is true, then if Uchiha Obito sucked the people and things into the Kamui space, could Hatake Kakashi release them if he had enough chakra?

It's just that the size of the Godly Space is unknown, and the details inside are even more unknown. Any imagination is just conjecture. But now, after accidentally coming to this Godly Space, Shuimu has understood that this place is not much different from the outside world. The various abilities brought by chakra are still effective, but there is no end to it. There is a pillar standing there, and no one knows what material it is made of. Of course, all this is not important. As Shuimu opened the scroll and released a small trembling flame, the black flame that fell on the pillar began to burn fiercely.

"Amaterasu and Kamui, let me see if I can find some clues this time."

Theoretically, as long as he reacts quickly enough, Obito can use Kamui to absorb Amaterasu's black flames, but the consequences are unknown. Mizuki remembered that in the original work, Uchiha Itachi used Amaterasu to plot against Obito after his death. Obito was caught off guard and half of his body was on fire. In this case, it would definitely be too late to use Kamui, so he probably used the Uchiha family's forbidden technique - Izanami to get out of the predicament. So Uchiha Obito, who appeared here a moment later, seemed unscathed.

However, the direct confrontation between Kamui and Amaterasu has never come. So this time, it is also an opportunity to solve a mystery. The origin of Amaterasu is still not well understood, and Kamui is even more in a fog. The relationship between Kamui space and Uchiha Obito's pair of Sharingan really makes Mizuki very curious.

And this time, it is a good opportunity to test it.

Shuttled between pillars and platforms, watching Amaterasu gradually begin to spread, the chilling black flames burned higher and higher.

"Fortunately, the Kamui space is large enough for me to escape for a long time. However, under what circumstances will Amaterasu naturally extinguish?"

This question has actually been around for a long time. If there is no one to control the flames of destruction that burn everything, it should develop into a black fire that threatens the entire ninja world. However, Uchiha Itachi has opened the Mangekyō Sharingan for many years, and Amaterasu must have used it more than once. Before the appearance of Kagutsuchi-no-Mikoto, the Mangekyō Sharingan eye technique that can control Amaterasu's black flames, there was no news of Amaterasu brewing a disaster. So it must be that under certain circumstances, Amaterasu has become ineffective on its own. What conditions must be met to cause Amaterasu to extinguish? This kind of thing, if you don't see it with your own eyes, you really can't understand it.

The black flames were burning in a wider and wider area. No one knew if there were any important items collected by Obito inside. If they were burned, he would be in trouble.

However, as Amaterasu burned, something seemed to have changed. The speed at which the black flame spread was slowly slowing down.

Mizuki released his perception and tried to find the reason for the change, but found nothing.

"Did something happen?"

Mizuki frowned and saw that Amaterasu seemed to be suppressed, but the range of the burning was far from reaching the limit of the Kamui space.

In an isolated space, there will be no people or objects to interfere, so does that mean the environment has changed?

With this thought in mind, Mizuki threw a fireball at Amaterasu's flames, and the black flames, which were originally a little weak, were extinguished in a short while.

"As expected, Amaterasu can burn everything, but it is not very effective against pure chakra. It is even somewhat restrained. Amaterasu, who can burn the tailed beasts to death, is actually completely helpless against the chakra of the tailed beasts. Uchiha Madara can even directly use superb chakra control to restrict Amaterasu, so it is not surprising that sealing techniques such as the Fire Sealing Seal are effective."

From this, Mizuki was almost certain that Amaterasu was being suppressed, and there must be something like chakra that suppressed Amaterasu's burning.

However, this kind of chakra cannot be sensed by Mizuki under normal conditions, so the answer is self-evident.

"Has the natural energy increased? This is a surprising result."
