There is a reason why the powerful ninjutsu Amaterasu appears in the form of flames. The burning of ordinary firewood will inevitably produce a large amount of carbon dioxide and other combustion products. If they cannot be dissipated and accumulate, they will hinder the burning of the flame.

The principle of Amaterasu is similar. Burning objects produces a large amount of natural energy, and this natural energy in turn suppresses Amaterasu, and it is reflected very quickly in this repressive divine power space.

All things are balanced and belong to their own categories. If there is something that has no natural enemies but has great destructive power, then the world is not far from destruction.

Amaterasu, when developed to a certain extent, is the best portrayal of the law of things turning into the opposite. This world will not allow all things to disappear endlessly.

Not only that, the speculation about Amaterasu's Black Flame also triggered Mizuki's anxiety about another mystery from long ago.

The Spiritualization Technique, a magical technique that can convert body and soul, broke Mizuki's judgment on a basic rule of the ninja world, which is the problem of mass-energy conversion.

If the body is matter and the soul is energy, then performing the spiritualization technique is like a super nuclear explosion. The energy generated will definitely kill any living thing within a hundred miles.

And this time, the things in the Kamui Space are matter. If they are converted into natural energy, then the energy generated by the things that Amaterasu has destroyed can already wipe out the ninja world.

But this did not happen. One possibility is that the law of mass-energy conversion based on relativity does not apply to the ninja world. Another possibility is that all chakras, ninjutsu, spirits, souls, and other things derived from natural energy are not energy, or in other words, not pure energy.

When the Eight-Tails Jinchuriki Killer Bee taught Uzumaki Naruto how to use the Tailed Beast Ball, there was a detail that made Mizuki more inclined to the second method.

The Tailed Beast Ball is difficult to practice. Naruto once said that the Tailed Beast Chakra is difficult to control because it is too heavy.

In Shuimu's cognition, tangible and substantial things are matter, intangible and intangible things are energy, and tangible and intangible things are fields. So what is chakra, an intangible and substantial thing? Anyway, with Shuimu's poor theoretical level, he really can't understand such advanced things.

But one thing is certain, the invisible and substantial chakra, when used by ninjas, is given shape and properties, forming all kinds of strange ninjutsu in the ninja world. And this process is the root of the ninja world being very different from Mizuki's original world.

Amaterasu is different. It completely erases the characteristic of "form" of matter.

"Is Amaterasu just a part of the laws governing the operation of the world?"

There is more than one technique called Amaterasu that can do this, but Mizuki has never seen anyone as domineering as Amaterasu.

The influence of the sacred tree has led to the formation of chakra in this world, which has fundamentally connected the bridge of communication between matter and energy, and the boundary between illusion and reality has become more blurred than ever before. The channel for dreams to shine into reality has been opened, and there is a way to turn will into power.

Smart people with wisdom are not the mainstream of this world. Paranoid people are the lucky ones favored by this world. It is not obvious in a little thing, but from the overall situation, people like Mizuki are really incompatible with this world. Even Orochimaru has a desire for immortality and knowledge, but what about himself? The petite and stubborn face of Xiaochun flashed in Mizuki's mind!

"There is still something I care about in this world!"

Shuimu laughed at himself, looked at Amaterasu who was slowly declining, walked forward slowly, and jumped down the deep ravine ravaged by the black flames. Under the continuous acceleration of gravity, Shuimu reached the bottom in a short while. Shuimu, who was knocked unconscious, took a long time to stand up. Looking at the space barrier under his feet.

"The seals and barriers formed by Amaterasu against energy and chakra are also ineffective. The boundary wall of the Kamui space has no flaws."

The border of the glittering and colorful divine space emitted a deep blue light. Shuimu stomped his feet hard, but not even a trace was left.

Then, Mizuki used his fists and fire attacks, but there was no effect. He also input chakra to detect, but there was no response.

"Normal ninjutsu attacks are ineffective, and physical attacks are useless due to lack of strength. This should fall into the category of Yin-Yang escape."

There was nothing they could do but give up exploring this space barrier.

"How boring! Amaterasu can't burn through the Kamui space, and Obito doesn't even notice it. Is there nothing we can do but wait?"

There was plenty of time, and Mizuki even used chakra to try to control the Amaterasu Black Flame. Unfortunately, this thing was too stubborn. It couldn't stop if it encountered something that could burn, and would automatically extinguish if there was nothing to burn. It was not affected by any guidance at all.

With no time control, it was unknown how long it had been, but a small, twisted vortex suddenly appeared behind Shuimu, and then slowly grew larger, with a tendency to suck Shuimu in.

“It’s finally here.”

Mizuki, feeling relieved, took off his combat vest and swung it at the black flames of Amaterasu. In an instant, the clothes were ignited by the black flames, and then were sucked into the space vortex along with Mizuki.

Mizuki endured the dizziness caused by the distortion of light and shadow, and when a blurry figure appeared in front of him, he stretched out his hand that was already burning due to the spread of Amaterasu, and grabbed the shoulder that was unable to dodge.

"Got you."

Without waiting to land, Mizuki endured the pain caused by being burned by Amaterasu and the unauthorized actions during the space teleportation, and clamped Uchiha Obito's neck with both hands.

"This is Amaterasu? How did you get it?"

The horrified Obito struggled to break free, but it was too late. Amaterasu's black flames had already spread to his body.

"Damn it, don't you want to live?"

"Even if you die, I will not die!" Mizuki smiled and held Obito's hand tightly.

Mizuki also knew the weakness of Uchiha Obito's Kamui. When inhaling and releasing things, there was no way to make part of the body virtual to avoid attacks. In order to catch the enemy off guard, Mizuki was cruel enough to himself.

Suddenly, Shuimu's laughter stopped and he fell down weakly.

"The grafting technique is more painful than Amaterasu! I'm at a disadvantage this time."

Jue's figure appeared behind the collapsed Shuimu. He looked at Shuimu, who showed no despair even at the brink of death, and said, "You are fighting so hard. It seems that we have been fooled and caught a puppet."

"Yeah." Obito, who was wrapped by Amaterasu, suddenly disappeared. A few steps away, an unharmed figure appeared, watching Mizuki being slowly devoured by Amaterasu, "I lost a three-magatama Sharingan..."
