This miraculous power should be a unique field constructed from laws, and only those who possess a profound understanding of those laws can create such a domain.
Ōtsutsuki Shiki was undeniably powerful, but attempting to establish a field like this was nearly impossible. Naruto could clearly feel that his own understanding of laws surpassed that of Ōtsutsuki Shiki.
Even for him, creating such a domain was not just a matter of comprehension. The energy required alone was an enormous obstacle.
Vaguely, Naruto felt that this domain resembled a miniature universe.
It was far more advanced than any spatial pocket dimension. It truly lived up to the power of the Rinnegan.
"Perhaps only those legendary beings in the True God Realm can truly understand something like this," Naruto thought to himself.
Before fully grasping the nature of the domain, everything remained hazy. Yet he could sense that this power was extremely important to him.
Being able to resist the suppression of the domain alone was already an incredible feat.
Naruto had not directly broken Ōtsutsuki Shiki's domain. Instead, he used a far more subtle method. While Ōtsutsuki Shiki remained the primary authority, Naruto had inserted himself as a secondary authority within the domain.
In theory, Ōtsutsuki Shiki should have had a way to counter this.
However, in Naruto's view, Shiki's understanding of the domain was still shallow. It was like someone using a tool without understanding how it was built. Naruto, on the other hand, had approached the level of its underlying structure, placing his control dangerously close to Shiki's.
From Naruto's estimation, a complete domain should be fluid, capable of changing its form and abilities at will.
By comparison, Ōtsutsuki Shiki's ability was merely a domain prototype.
The battle resumed.
This time, however, Ōtsutsuki Shiki noticed something different. Although Naruto had been briefly suppressed at the start, his strength recovered almost instantly.
"How is this possible? You weren't affected!"
Disbelief filled Ōtsutsuki Shiki's expression.
Even among the Ōtsutsuki, domain abilities were rare. Not even Ōtsutsuki who wielded abilities like Amaterasu possessed such power. With a domain in place, even elite techniques could not easily kill him.
Only by using overwhelming power to forcibly shatter the domain, followed by superior combat strength, could one hope to defeat him.
The suppressive strength of the domain depended on the opponent's level. Against someone in the same realm, it reduced their strength by roughly twenty percent. Naruto had already been acknowledged as an equal.
As for anyone below the Fourth Stage of the Demi-God realm, they would be completely immobilized under the pressure of this domain.
"Your ability is certainly strange," Naruto said with a faint smile, "but I've already seen through it. Surrender, or withdraw from the shinobi world."
His tone carried a trace of mockery.
At their level, the difference in strength between them was minimal. A decisive victory could not be achieved quickly. Their bodies possessed terrifying endurance, and they could draw chakra from the void to recover continuously.
"What a joke," Ōtsutsuki Shiki sneered. "Whatever trick you used to avoid Takamagahara's suppression, it changes nothing. The supremacy of the Rinnegan is beyond your comprehension."
Naruto chuckled softly.
At his core, Shiki was still bound by the obsession with bloodline superiority. That arrogance was etched into his very being.
Naruto had seen this countless times in the shinobi world. It no longer surprised him.
For a brief moment, a thought flickered through his mind like a spark, but it vanished just as quickly.
Naruto shook his head. Losing focus in a battle like this would be fatal.
Ōtsutsuki Shiki suddenly began burning his divine chakra. His aura surged dramatically, but the cost was immense, with his energy consumption increasing more than tenfold.
"In my name…"
"Judgment!"
The sky trembled.
The atmosphere shifted as if the heavens themselves were gathering power. High above, a vast mass of energy condensed, stretching across tens of thousands of miles, radiating an overwhelming and terrifying presence.
Naruto's expression turned serious.
If his judgment was correct, what hovered above them was not ordinary lightning. It was a manifestation of a fundamental chakra law, a higher-order Lightning Release that far surpassed any conventional technique.
The rolling lightning surged like a tide, thunderclouds gathering layer upon layer as their pressure mounted, causing even distant observers to tremble.
…
The battle between the Ōtsutsuki Clan and the shinobi world had long since drawn the attention of major forces across the universe. When Ōtsutsuki Shiki revealed such terrifying methods, it shocked many factions that had never held the shinobi world in high regard.
The only reason they had not moved to divide and seize it was their caution toward the Shinigami Clan.
The birth of the Rinnegan in the past was known to very few. Its power was only compatible with the Ōtsutsuki Clan and the Shinigami Clan. The Shinigami Clan had managed to obtain a portion of the Rinnegan's authority and standing from the shinobi world.
As for the Ōtsutsuki Clan, they had remained silent on the matter. No one knew why. Whether they had reached some agreement with the Shinigami Clan or suffered losses in a hidden conflict, the result was the same. The Shinigami Clan gained a massive advantage.
By the time other forces in the universe learned of this, it was already too late.
Because of the unique nature of the Rinnegan, the shinobi world was destined to grow into a major force. However, reaching the level of a top-tier power was still considered nearly impossible.
That judgment also stemmed from one name that had spread across countless galaxies.
Uzumaki Naruto.
By now, most major forces were already aware of his existence.
And the battle between Ōtsutsuki Shiki and Uzumaki Naruto had left even neighboring galaxies in fear.
The surrounding region, spanning light-years, had been completely cleared by their clash. Planets had been reduced to dust in the aftermath.
From the very first day their battle began, scouts had already arrived to investigate. The moment they detected the immense fluctuations of chakra and energy, they fled without hesitation, gripped by terror.
They feared that these two monstrous beings might drift into their territory and, by sheer collateral damage, erase entire planetary systems.
The nearby galaxies lacked any dominant superpowers. They were inhabited only by mid-tier factions and scattered races.
Even so, anyone capable of sensing the traces of this battle was left stunned.
Powerful individuals concealed themselves in distant regions, observing in silence. Others relied on advanced technology to monitor the conflict from afar.
Those with sufficient strength could witness the battle clearly, using secret techniques to observe every exchange.
As for the technologically inclined, they relied on calculations, measuring energy outputs and environmental distortions to estimate the scale of the battle. Their methods were crude, but still enough to grasp its terrifying magnitude.
A battlefield that stretched across light-years was already beyond comprehension.
And now, the vast thundercloud mass hanging above resembled the gaze of a god descending upon the universe.
If there truly existed a god, then this was what its power would look like.
Even a major force would struggle to withstand such might.
After all, Ōtsutsuki Shiki stood among the very peak of the universe's powerhouses.
The supreme war general of the Ōtsutsuki Clan.
A battle-hungry existence who had repeatedly waged war against the other great peak factions.
To countless beings across the cosmos, he was a figure worthy of fear… and reverence.
