Chapter 141: The Ultimate Power

Such power caused the Nine-Tails immense trouble in the original story. Fortunately, Naruto ultimately defeated Shuren, reclaiming Hanabi’s eyes, and only then did the golem cease to function.

But now, the situation is different. Momoshiki Ōtsutsuki is utilizing a colossal Reincarnation Eye as a power source.

This giant Reincarnation Eye is formed by the fusion of all the Byakugan from the various branches of the Ōtsutsuki descendants, containing a chakra volume that far exceeds that of a typical Tailed Beast.

It’s not something that can be consumed or drained in the usual way.

Moreover, the giant Reincarnation Eye is sealed with an intricate curse.

Anyone without Hyūga lineage who touches it will have their chakra completely drained, making it impossible to dispel.

Note the distinction: it is those without Hyūga bloodline, not necessarily those without Ōtsutsuki bloodline. There is a subtle but crucial difference.

This explains why, in the original story, though Naruto belongs to the Uzumaki clan and is a descendant of Hagoromo, he could not touch the Reincarnation Eye directly.

In the end, it required Hinata’s chakra to destroy the giant Reincarnation Eye.

Otherwise, with the giant Reincarnation Eye’s support at that time, Naruto might never have been able to defeat Shuren.

Now, only Uchiha Sasuke stands here alongside Uchiha Sai, and both of them are descendants of Hagoromo, not of the Hyūga clan.

Under these circumstances, they cannot destroy the giant Reincarnation Eye.

Therefore, trying to take shortcuts in this battle is impossible.

What he can do now is to rely on brute strength to suppress the golem while simultaneously eliminating its controller, Momoshiki Ōtsutsuki.

Only by doing so can this battle be won.

Of course, thanks to the Terra teleportation portal, there is a second option: to retreat immediately.

Their current strength isn’t sufficient; they can avoid combat for now. Terra’s energy reserves are ample, and his need for the giant Reincarnation Eye is not urgent.

He can return later when he has grown stronger.

“But just walking away now would be too cowardly. How will you know unless you try?”

Uchiha Sai ultimately chooses not to leave immediately. Instead, he prepares to test the golem’s strength.

After all, all the intelligence so far is merely conjecture. What if the golem looks formidable but is ineffective?

Besides, he is curious about how much the lunar branch differs from the Hyūga clan.

This branch of the Ōtsutsuki descendants on the moon has produced Shuren, a highly devolved Ōtsutsuki of great power—far beyond anything the Hyūga could match.

In a short time, Uchiha Sai is ready for battle.

Nearby, Itachi, after a moment of hesitation, anxiously says, “Sensei, what should we do? Maybe we should just leave…”

If Uchiha Sai hadn’t remained calm, Itachi would have fled long ago.

Yet even with Uchiha Sai present, Itachi does not believe their teacher can win.

Putting aside the terrifying golem, this is the moon—the stronghold of the Ōtsutsuki descendants.

How long can they possibly hold out here?

Uchiha Sai is somewhat more confident, though he only has the twin tomoe Sharingan.

If caught in the crossfire, death might come before he even knows it.

Seeing Itachi’s anxious expression, Uchiha Sai offers a calming glance and says, “Don’t worry. Even if the battle is unwinnable, I have a way to get you out of here.”

Upon hearing this, Itachi opens his mouth to say more but ultimately remains silent.

He does not understand where Sai’s confidence comes from, but given their circumstances, trusting him seems the only choice.

Alone, Itachi would face even greater danger.

He now deeply regrets his decision—so much so that he wishes he had never followed Uchiha Sai out here.

Even enduring the merciless training back in the village would have been preferable to risking his life.

“Itachi, it seems you don’t trust your teacher,” Sai remarks with a knowing smile.

Then his expression suddenly shifts to one of seriousness.

Before Itachi can respond, Sai speaks in a low voice, “It’s not your fault. After all, you still don’t understand the true source of our Uchiha’s ultimate power.”

“Ultimate power?” Itachi is puzzled. “Isn’t it the Mangekyō?”

In his understanding, the Mangekyō Sharingan is the pinnacle of the Sharingan—the supreme eye of the Uchiha.

Sai does not deny this but calmly replies,

“The Mangekyō is indeed the strongest technique of our clan, but why does it achieve such effects?”

“Since the end of the Warring States period, many have forgotten the true power the Mangekyō holds.”

He pauses, then continues, “But you are an Uchiha and my student, so you must remember this!”

Before Itachi can react to his teacher’s sudden words, he senses a change in Sai.

A chilling, violent youthful power suddenly radiates from him.

Black-golden light bursts forth, accompanied by a deafening roar as a massive skeletal frame envelops Sai.

The skeleton rapidly grows, muscles form, and armor begins to cover the frame.

Then, an ethereal energy, wholly different from before, emerges.

Four divine wheels float above the back of the summoned entity, Susu.

This time, before Itachi can ask, Sai declares, “This is the true power of the Mangekyō—the Susu Nōko. And it is still incomplete; it can continue to grow.”

“Susu Nōko, huh?”

Itachi instinctively takes a step back, overwhelmed by the imposing aura.

Facing a similarly colossal figure, he finally understands the source of his teacher’s confidence.

But can this truly overcome the golem?

Itachi compares the golem and Susu; the golem’s size dwarfs Susu by several times.

In sheer size, Susu falls short.

“Stay here. Don’t wander off,” Sai orders, casually setting up an Uchiha Flame Formation around Itachi to ensure his safety.

Then he leaps onto Susu.

Facing the golem, Sai is prepared to unleash the full power of the divine wheels.

The wheels begin to spin rapidly, and Susu takes flight.

Sai knows this battle will be tremendously difficult; the golem’s indestructibility is truly a nightmare.

Moreover, the Ōtsutsuki descendant likely wields techniques far surpassing those of the Hyūga, doubling the challenge.

Even with Susu and the divine wheels, victory is not guaranteed.

“Hopefully, the power of the divine wheels will make a difference,” Sai thinks.

His hesitation stems from the fact that Susu and the divine wheels are still growing; they are far from their ultimate form.

Meanwhile, the golem was likely personally crafted and passed down by Hyūga himself.

There is still a notable gap in power between the two sides, not easily bridged.

Lost in thought, Sai sees Momoshiki Ōtsutsuki mount the golem.

Despite Sai’s control of Susu in flight, the massive size difference makes him appear small.

But Sai does not mind.

A huge versus small confrontation—the battle is about to begin!
