As the name suggests, the "Eye of the Universe" is an eye capable of monitoring the entire universe. It is also used to devour all inherited bloodlines continuously.
"Rinnegan, Tenseigan, Sharingan, Byakugan, Akagan, Ketsuryugan..."
Over these ten years of conquest, Yuuji collected too many eyes, especially after killing many Otsutsuki, from whom he extracted their eyes.
"You only need to refer to the composition pattern of the giant Tenseigan, and gather these many eyes to create a unique super eye."
Yuuji began fusing the eyes in his possession, eventually realizing he didn't have enough.
"The materials are still too few; they could work, but they're far from the colossal eye I envision."
Yuuji felt a bit regretful.
Soon after, for some reason, news of Yuuji's disappointment quickly spread across his massively expanded planet.
"What? How can this be? Lacking eyes, you say? I have eyes, I can..."
"Stop, idiot! Your eyes are just normal; what use are they for? Didn't you see the Uchiha and Hyuga clans beginning mass suicides next door? Their eyes are somewhat useful!"
"But they're not that useful; ordinary eyes don't mean much, and those with Sharingan and Byakugan can't just kill themselves. They'd lose their powerful eyes upon revival and have to find a way to reawaken them..."
"To alleviate Yuuji-sama's frustration, we only have one option: go after the Otsutsuki. Wipe them out, eradicate their clan, destroy all their people; that should be enough."
The entire planet was abuzz, with countless individuals eagerly anticipating reaching the Otsutsuki home planet.
"Madmen..."
Kaguya's head rolled on the ground, her heart racing as she watched these insane beings.
Brainwashing with Infinite Tsukuyomi? Unthinkable.
"Grandmother, you've seen enough, haven't you? If you are, we'll provide you with a body; this can't go on."
Indra couldn't bear it any longer.
She was their grandmother after all. Rolling on the ground with only a head, what kind of situation was this?
Kaguya scoffed, "I won't use a body provided by that guy. I'm still an Otsutsuki. If that guy loses, our three fates might just turn around."
Is Yuuji possibly losing?
Asura thought momentarily, then whispered, "Even if he loses, he surely won't die. Over the years, how many planets has he destroyed? How many people has he slaughtered? How many life-bearing planets has he turned into wastelands? He must have scattered countless cells across the universe during this process."
Kaguya remained silent.
He could rise again as long as a single cell survived. Such insane capability would make anyone's scalp tingle.
"Let's see, it all depends on the God of Chakra. Even though he's attacked many planets and plundered vast amounts of natural energy, he may not win."
Because most of the natural energy was directed to the flesh and blood planet, not absorbed by him.
Even if Yuuji's power was growing, did he have the capability to compete with the God of Chakra?
Despite this, Kaguya wasn't sure if the God of Chakra had even been born or how strong it might be.
But Yuuji had already considered the issues she could think of.
"We're nearly there, at our current speed; in ten more years, we'll reach the Otsutsuki homeworld..."
Yuuji pondered.
He didn't have much information regarding the God of Chakra, but he could be sure of one thing: the complete form of the God of Chakra had not yet emerged.
This mysterious god was, at best, an incomplete form, far from its theoretical peak. Yuuji saw this opportunity.
Is he not fully formed? No problem. He would slaughter and devour the God of Chakra, allowing himself to become the complete form of the God of Chakra, ruling all the chakras in the universe, and then his problem would be solved.
At that time, the entire universe would become Yuuji's grand hunting ground, with numerous life-bearing planets and countless amounts of natural energy; Yuuji could absorb however he wished.
"The Otsutsuki clan might have realized something is wrong by now, given how many of their people I've killed... Just in case, I should activate the multi-temporal resonance plan."
Yuuji took out the artifact he had sealed long ago—The Heavenly Plow of Time!
"I'm suffocating, you finally remembered me?" The turtle poked out its head.
"Cut the chatter, open the time tunnel."
"Understood, but to which time point do you want to go?"
"All of them."
"Ah?"
"I said I want to go to all the time points control all the timelines," Yuuji said slowly.
The turtle was confused.
Control all timelines?
"That would completely mess up the universe's timeline! Known and unknown histories would be unrecognizable!" the turtle hastily said.
"Does that matter? I am history, I am time itself, that's what I want."
Yuuji grabbed the turtle and slowly exerted force.
The turtle had no choice but to open the time tunnel.
What appeared was a circular platform.
Around the platform, beams of light rapidly ascended from below, cycling continuously.
Each beam of light represented a time node.
Yuuji's form squirmed, and endless masses of flesh soon burrowed out, rushing into each light screen.
"That should do it when necessary; these will give me tremendous power."
Yuuji split off a clone to stay with the turtle there.
His own body returned, focusing on preparing for the grand battle with the Otsutsuki.
The time passed.
Finally, Yuuji's flesh and blood star approached the Otsutsuki home planet.
"Are they coming? The enemy who has been slaughtering and attacking our clan... what are they?"
The entire Otsutsuki clan began recalling their people, even those from branch families, readying for battle.
On the Otsutsuki home planet, not only were many Otsutsukis gathering, but countless Ten-Tails were also rearing their heads.
From afar, it was a scene of demons running wild.
"Patriarch, who is the enemy, and what is their origin? Why are they targeting our clan?"
Even on the brink of battle, many Otsutsukis were confused.
They didn't even know what was happening.
The patriarch was also bewildered, but he vaguely sensed it might be related to that visitor from another universe decades ago.
Other than that, he could think of no other reason.
Logically, their clan had actively explored the universe, destroying countless planets and civilizations; they deeply understood the universe.
But now, this bizarre flesh and blood planet suddenly emerged, charging towards their home planet, which was outrageous.
These powerful beings had appeared seemingly out of nowhere without any prior intelligence.
"I want to emphasize that the enemy is very strong, completely different from the natives of the various planets we've faced in the past," the patriarch said gravely. "Perhaps it's related to...never mind, it's unverified, so let's not discuss it. Prepare for battle."
"We've gathered so many Ten-Tails, and it's a home-ground battle; we must win!"
"Yes, this is the first time I've seen so many Ten-Tails. These dangerous creatures always want to eat our people to evolve into complete forms..."
The numerous Ten-Tails were highly agitated, roaring continuously.
Time we progressed.
"Strike now; don't let their planet crash into our home planet! All clansmen with space abilities, use your space-time dojutsu to intercept them; try to destroy the enemy's planet!" the patriarch suddenly shouted.
Many Otsutsukis took action, launching various space-time dojutsu in succession. Suddenly, visible space barriers and fractures appeared, blocking the flesh and blood planet's path.
"Using space to dismember our planet, huh? Well, that tactic is pretty standard, nothing surprising; it was expected," said Kabuto, pushing up his glasses as he observed the arrayed space barriers.
The methods available were ultimately limited at a level like theirs and in a war between two planets.
Using dense space-time dojutsu for probing was a very standard tactic.
But the problem was that there was a bug-level existence on their side.
"Space... All those who show their space abilities before me are laughable."
Yuuji opened his eyes, focusing on a point ahead.
A powerful purple pattern erupted, melting away everything in its path. All spatial obstacles, like flowing water or a gentle breeze, disappear without a trace.
This one action turned countless Otsutsukis pale.
"This...how is this possible? Instantly erasing so many of our dojutsu!"
"Damn, it seems they were prepared. They are probably anticipating our move, so they devised a counter-tactic!"
"Indeed, the enemy knows us very well."
Only the strongest among the Otsutsukis looked seriously troubled at this point.
"No, that's not right..."
"It's wrong; it seems only one person made a move."
"One person and he resolved so many space-time dojutsu?"
"This isn't just any strong person."
The patriarch took a deep breath; he knew the enemy had come prepared, extraordinarily knowledgeable, hostile towards their clan, and terrifyingly powerful.
He was increasingly convinced that the enemy was related to that visitor from another universe and even boldly guessed that the person who had just acted was from another universe!
Was it because they knew the Otsutsukis were a dominant power in the universe, so they deliberately came knocking?
"Get ready to fight, just in case..." the patriarch hesitated but couldn't decide.
The God of Chakra... it was a risky affair.
Finally, the two planets drew closer, only a few hundred thousand kilometers apart.
Such a distance, merely a single space transfer away, was nothing for the Otsutsukis, adept at using space-time dojutsu to attack other planets.
"Go ahead, wipe out all the Otsutsukis. All spoils, except for the eyes, belong to the individual," Yuuji ordered.
Excitement surged through the flesh and blood planet, which had slaughtered numerous planets.
"The moment has finally arrived; once we deal with these guys, the war should be over, right?"
Itachi looked up, worried.
Next to him, Sasuke whispered, "Yeah, the Otsutsukis are the enemy of all of us; we must eliminate them. Once they're gone, the teacher probably won't launch any more wars."
Itachi was still worried and always felt things weren't so simple.
Was all this done just to address the threat of the Otsutsuki clan?
Just to create that so-called Eye of the Universe?
Itachi recalled a rumor that had circulated many years ago: at the end of the Fourth War, Orochimaru displayed a different form, and after using the Eight Branches Technique, his eight snake heads transformed into three golden dragon heads...
He hoped he was overthinking it.
The Otsutsuki patriarch wanted more information and shouted, "Who exactly are you, and from where do you come, and why do you attack our clan?"
Yuuji stood up, flew out, and looked down at the planet below.
In his field of view, he could see the number of people there.
"Alright, the total population is less than a hundred thousand. Powerful individuals was only about a hundred which was quite few... there was plenty of Ten-Tails though, many of which are small, clearly not fully nurtured yet."
Yuuji took note of the situation of the Otsutsuki clan.
A hundred or so six-path level fighters were impressive, fitting the profile of a cosmic sovereign race.
King Ghidorah in the next universe doesn't have more than a hundred planet-level subordinates.
Yuuji looked across, his voice calm but piercing through space, covering the entire planet, "You're mistaken about one thing. I'm not against you; it's just that you're in my way."
"Arrogant! It seems you've made up your mind. I don't care where you're from or what you want in our world, but you will regret this!"
The war erupted immediately.
Numerous space portals opened from the flesh and blood planet, and a large number of warriors rushed in and came to the front line.
The battle became brutally intense from the start.
As expected, Yuuji's side was at a severe disadvantage.
In terms of the quality, his side was far inferior.
The enemy had over a hundred six-path-level beings and as many Ten-Tails, not to mention countless super-kage-level fighters below the six paths.
And on Yuuji's side, there were only about a dozen super-kage and six-path level fighters.
But their advantage was their fearlessness of death.
Explosions occurred in rapid succession.
Yuuji's troops were decimated at an alarming rate.
"Hahaha, is that all?"
"Too weak; they only outnumber us!"
"Well, isn't it just my imagination? There are so many of them; any single one placed on a native planet would be quite powerful."
"It's not your imagination; the enemy is continuously sending people. Currently, the number of participants in the battle is... a hundred times ours! And it's still increasing!"
The number was one thing.
Gradually, some Otsutsukis realized that the people they had just blasted to bits were back in the fray, looking as lively as ever...
This was outrageous!!!
