Ninja Ice House

Chapter 528 Manifestation

Some things, upon careful consideration, have causes and consequences that are actually quite debatable.

In the original timeline, what caused Uchiha Sasuke to awaken the Mangekyou Sharingan? Was it because he faced the threat of death at the last moment, because of intense fear and resentment at not being able to take revenge himself, or because of regret after learning the truth, or because of the intense emotional impact of killing his own brother?

Or maybe both?

Could different emotional stimuli affect the eye techniques and eye power after awakening the Mangekyou Sharingan?

It seems so, but it's not that big!

The so-called "eye that reflects the soul" is naturally closely related to everyone's soul. But are your thoughts and ideas truly the real desires of your soul?

not necessarily!

For example, the chakra of tailed beasts can greatly amplify the fluctuations of certain extreme emotions in a jinchūriki.

Provoked and manipulated by Shukaku, Gaara killed Yashamaru in a fit of rage. But did he really want to do it? Will he regret it afterward?

Of course, in another sense, it doesn't really matter what your true thoughts are. As long as you can open your eyes, you can make up for it later!

It might be impossible to make up for it!

This is where Sasuke Uchiha's contradiction lies: he wants to kill Itachi Uchiha, but he doesn't necessarily have to; however, his desire for revenge is absolute, and his will to kill his enemy is extremely strong.

However, Sasuke Uchiha is a bit different now. His intelligence and common sense are normal, and he is even more humane than other members of the Uchiha clan.

If he knows more information he shouldn't know, and learns some secrets that are impossible for him to know, making his intelligence dominate his mind, he will be harder to fool, and it will also increase the difficulty of awakening the Mangekyou Sharingan.

Therefore, a little bit of external interference is needed!

Coincidentally, the laced-up Indra chakra began to become the dominant factor.

Before awakening the Mangekyou Sharingan, Sasuke Uchiha would not have been able to access, understand, or apply Indra's chakra.

But now, there is a power of the same level supporting it.

Although the cursed seal, the power of the demon god, and miscellaneous natural energies were expelled and sealed, the Demon Sword Onikiri was still there. Unlike the relatively fragile Totsuka Blade, this thing was extremely hard and could not be destroyed by ordinary force.

So, after the black smoke-like energy disappeared, in Uchiha Sasuke's barely perceptible senses, a dark and profound energy within his body began to activate and surge into the Demon Sword Onikiri.

Before long, a viscous chakra with a black base and blue striped energy bands on its surface expanded rapidly, growing taller and larger, into a monster over ten meters tall with a blue face and fangs, black spiky wings on its back, a dark longsword in its hand, and a silent roar emanating from its mouth.

Meanwhile, Sasuke Uchiha manipulated the giant monster from its chest.

After this battle avatar, which seemed somewhat similar to Susanoo but was fundamentally very different, appeared, Itachi Uchiha's face clearly showed a hint of surprise.

Evil, cold, indifferent, and completely disregarding humanity and even ordinary living beings, spread in all directions. This energy, which seemed to condense all the negative emotions of the ninja world, even made Itachi Uchiha, who was enveloped by the fiery red Susanoo energy, feel a slight tremor and an instinctive feeling of disgust.

"It resembles a tailed beast, but it's also very different!"

Tailed beasts are condensations of chakra, natural energy, and the combined will of living beings mixed within them, shaped by Yin-Yang Release. The existence before us, however, is like a collection of more fundamental negative energy, closer to the most primal instincts.

"Operating this thing would significantly shorten a ninja's lifespan! But..."

Kosugi Bokusui looked at the resilient chakra that should have dissipated with its owner's death a thousand years ago, as if it were an echo of life still existing.

However, the nature of this energy is too high. For ordinary people to use it, it would probably be difficult to even sustain it by squeezing out their physical strength, mental strength, and chakra. They would need to consume even more primal life force to maintain it.

Uchiha Sasuke had not yet awakened the Mangekyou Sharingan, nor did he have Susanoo to contain the reincarnation chakra of Indra to help it manifest its power, but he had a substitute.

Kaguya Otsutsuki asked with a hint of inquiry and curiosity:

"Did you foresee this day and give him the sword beforehand? What a lucky kid, truly one of the chosen ones of this era, favored by the ninja world... the whole world is helping him!"

"No, you're overthinking it. How can you have so much foresight? Many times, things just happen naturally, like water flowing into a channel. Because the external circumstances have changed, even if it's not as sharp, there should be other factors that will lead the situation to a similar outcome."

The current battle is clearly in a head, and dragging it out until now is very disadvantageous for Itachi Uchiha. From the start of the battle until now, he first went to Sunagakure with his partner to assist in capturing the Jinchuriki, and then spent a long time coordinating the extraction of the One-Tailed Shukaku. After the two extremely energy-consuming techniques, Illusionary Body Technique and Illusionary Dragon Nine Seals, he fought a battle with the Sunagakure pursuers and Konoha reinforcements, and then rushed to fight his younger brother Sasuke Uchiha.

The evenly matched battle lasted for quite some time. In addition, the Mangekyou Sharingan's eye techniques had been used more than once. Even with Kosugi Bokusui's secret assistance in replenishing his eye power and alleviating the near-collapse of his body due to the outbreak of bloodline disease, such high-intensity consumption was truly too damaging to his body.

Even a strong and healthy ninja cannot withstand such abuse, let alone someone who is already suffering from a long-term illness.

Sasuke Uchiha's physical condition wasn't great either, but it was still better than Itachi Uchiha's, and he was younger and had a stronger recovery ability.

The Demon Sword Onikiri, which shimmered with blue and black energy, and the Totsuka Blade, which danced with crimson flames, clashed several times in the air. The surging energy spread outward with the natural energy tide, and Deidara, the Sand Ninja, and the Konoha Ninja who were fighting in the distance all felt it.

The half-body Susanoo, which had previously used an energy-saving mode, could no longer hold up. After entering its third state, Itachi's battle avatar was even a level above Sasuke's, but it did not have the upper hand in terms of power.

Realizing that further delay would disrupt the decisive battle in the distance and the fateful duel between the two brothers, Uchiha Itachi once again unleashed the incredibly powerful Mangekyou Sharingan technique—Amaterasu.

The raging black flames can incinerate everything, but they are different from the cold, negative energy of the Demon Sword Onikiri that carries the erosion of the spirit. In the clash between the two, Amaterasu is still superior. Without sparing his eye power and chakra, Itachi Uchiha's explosive power in battle is obviously stronger.

Just as the Amaterasu black flames were unleashed, Uchiha Itachi suddenly paused, looked at his hands, and realized that a stream of Yin-attribute chakra had unknowingly wrapped around his body and was continuously seeping into his body.
