"Who is this guy?"
Through the purple stone linked to the giant Reincarnation Eye, Otsutsuki Toneri looked at Izayoi, whose entire body was enveloped in green chakra. Though he appeared calm on the surface, his heart was in turmoil.
This chakra level... was at least a hundred times his own.
And there was that tornado which instantly annihilated the wireless puppet army, and that ability to absorb the purple light beam... This person's strength was far beyond his own.
Could it be that the seal connecting the space channel between the moon and the Earth has already been discovered and broken?
Or... could this person be someone from the ninja world who flew from Earth to the moon?
Suddenly, Otsutsuki Toneri seemed to notice something and muttered, "He has horns like the ancestors... is he a descendant of the Sage of Six Paths?"
With that thought, Toneri immediately poured a large amount of chakra into the purple stone, trying to open the light wall of the artificial sun and pull a meteorite from outer space using gravity.
Unfortunately, he was far too weak now.
His chakra wasn't enough to fully mobilize the power of the giant Reincarnation Eye. He couldn't even monitor the ninja world—he was like a severely nerfed version of Kaguya Otsutsuki in Izayoi's eyes.
Izayoi made just one move, and Toneri realized the vast difference in power.
Izayoi raised a hand and formed a chakra bead, which transformed into a piece of metal engraved with the Flying Thunder God formula.
Then, the metal vanished.
Izayoi disappeared along with it.
Seeing him vanish into thin air, Toneri hurriedly used the giant Reincarnation Eye's perspective ability to locate Izayoi's chakra.
And in the next second, Toneri was shocked and broke out in a cold sweat.
Izayoi's chakra signature appeared behind him.
Before he could react, a palm landed on his back, and a green beam of light pierced through his body.
Toneri's body softened, first dropping to his knees, then collapsing completely.
The purple stone, having lost its chakra supply, dimmed and fell to the floor.
At the same time, a dazzling green light suddenly burst from beneath a lake in the ninja world.
The enormous chakra instantly drew the attention of all the White Zetsu clones scattered across the continent, who were searching for seals or clan emblems.
Soon, Black Zetsu and White Zetsu became aware of the situation and brought Uchiha Madara's wood clone to the bottom of the lake.
"A lake within a lake... Such a special location actually exists in the ninja world?"
Uchiha Madara looked around, then stared at the green lake and asked, "How did you find this place?"
"This place appeared all of a sudden, Madara-sama," White Zetsu reported. "Clones of mine have passed through this area before, and it always looked like just a cave under the lake, so we never paid it much attention."
"But just now, a special chakra erupted from here. When the clone returned, it found this green lake. That chakra likely signaled that a seal had been lifted."
"Did you already investigate inside?" Madara asked.
"I sent in a clone. There's a space channel inside," White Zetsu replied with a strange look.
Not just him—even Black Zetsu and Madara were surprised.
"Interesting... Was this a coincidence, or intentional?" Madara mused. "I've been searching for this for months, and even the Samsara Eye couldn't detect the chakra of the seal. But now it suddenly opens on its own. Could it be bait for me?"
"Madara-sama, do you really want to go in?" Black Zetsu asked, visibly worried.
They had searched for a thousand years but never found the space channel to the moon.
Even using Madara's wood clone and a White Zetsu army, the Samsara Eye couldn't detect the sealing technique's chakra.
Now the seal just opened—too suspicious.
It was unlikely that Otsutsuki Toneri would be so generous as to invite them to the moon. This felt like a trap, a home-field ambush.
"When the enemy takes the initiative to invite you in, why not go?" Madara said with a smirk. He formed a seal with one hand. "But first, let's throw in a chess piece to test the waters."
"Ninjutsu—Impure World Reincarnation!"
With that, a coffin rose from the ground.
As the lid fell open, the Second Tsuchikage emerged.
In the next moment, his figure distorted and vanished.
He had activated Dustless Illusion Body, the technique that earned him the title of "The Incomparable."
This secret technique was even more undetectable than Transparent Release—his chakra couldn't even be sensed.
Combined with Earth Release: Light-Weight Rock Technique for flight and Bloodline Elimination: Dust Release, which disintegrates matter on contact, the Second Tsuchikage was among the most brilliant Kage-level geniuses.
Madara then used his wood clone to remotely control the invisible Second Tsuchikage and sent him into the channel created by Otsutsuki Hamura.
Since this clone was only a wood clone made using Madara's chakra, Izayoi had no way of knowing about it.
At the same time, Izayoi was pondering how to handle Toneri.
Killing him would be a waste.
In these years, Toneri had grown a lot.
Back then, he was born without a Byakugan and hadn't yet cultivated, only carrying a red Otsutsuki bloodline bubble. That alone gave Izayoi a huge advantage.
Now, eleven years later, Toneri had unlocked three purple entries: Chakra Control (purple), Kage-level Aptitude (purple), and Puppet Master (purple).
If only he had Byakugan… With proper cultivation, he might already have a golden entry by now.
Red entries were rare—killing someone with such potential would be a real waste.
Moreover, Toneri's high degree of bloodline regression sparked a bold guess in Izayoi's mind.
So, he separated a wood clone to take Toneri back to Earth, while his main body picked up the purple stone and took control of the giant Reincarnation Eye.
But Izayoi didn't immediately study it.
Instead, he headed to the Otsutsuki clan's library.
Just like the Hyuga clan's, it was full of books and scrolls.
Rather than browsing one by one, Izayoi transmitted information to his wood clone in real-time, allowing it to read Toneri's memories via the Spirit Ball Technique to locate the most valuable inheritance records from the past thousand years.
If Toneri hadn't read them, he'd just take everything back and slowly sift through it.
But luckily, Toneri's father had passed on all the most precious knowledge of the Otsutsuki clan to his son.
Soon, the wood clone reported good news.
After digesting the information, Izayoi flew to a bookshelf and retrieved an old scroll.
There were no seals on it. The scroll was aged and worn.
Izayoi summoned a green light ball with chakra beads to illuminate the dim library and carefully unrolled the scroll.
And the next second, he cursed, "Damn it!"
The scroll was filled with dense, unreadable script—practically illegible.
Clearly, the writing from a thousand years ago was very different from modern script.
Still, this only confirmed that it was left behind by Hamura himself.
It was like finding a treasure, only to discover it was locked behind a password vault.
Izayoi was suddenly glad he didn't kill Toneri—otherwise, he'd have to dig up a grave and use Impure World Reincarnation to summon a dead Otsutsuki clan member.
But he didn't want to go that far.
Because he was afraid of meeting Hamura's soul.
As someone who achieved Six Paths level by condensing the Seeking Truth Jade through bloodline and the Reincarnation Eye alone, Hamura was likely still influencing the living world—just like his brother Hagoromo.
He might even still have the Seeking Truth Jade as a soul.
Since neither brother had come to him yet, Izayoi didn't want to meet them prematurely—not until he had both the Bloodline Net and Seeking Truth Jade.
So, Izayoi used chakra beads to create a large storage scroll.
Yin-Yang Release combined with chakra beads could not only create comprehensible objects but even mysterious or unknown ones—like the Super Hurricane Ball, a secret technique combining multiple nature transformations.
With his Sky Control (Red) talent—an innate Otsutsuki time-space gift that was awakening step-by-step—Izayoi easily created the storage scroll.
Once he fully mastered the Samsara Eye's power and the potential of Sky Control (Red), crafting space channels like Hamura's and teleportation arrays between Earth and the Moon would be no problem.
But only if his Yin-Yang Release understanding was deep enough.
Izayoi's Samsara Eye had the Yin-Yang Release inheritance, but just the foundational level.
Hamura and Hagoromo had taken Yin-Yang Release much further using their Ten-Tails chakra, talent, and centuries of experience.
The Six Paths tools, the space channel, the Seeking Truth Jade, the Six Paths Seal... all were products of their mastery.
The scroll in Izayoi's hand was one of Hamura's legacy texts—a complete Yin-Yang Release technique.
If he could decipher and master this, Izayoi's chakra beads would grow vastly stronger.
With that, he could potentially create the Seeking Truth Jade at any time.
After storing all the thousand-year Otsutsuki knowledge into the scroll, Izayoi created a wood clone to return it to the ninja world.
The main body then floated before the giant Reincarnation Eye in the ancestral hall and inspected it closely.
The eye was golden: gold for the sclera, yellow for the pupil.
Its internal pattern resembled Izayoi's, though his was white and this one was gold.
The pupils also differed—Izayoi's were like coronas, while this eye's were dazzling white.
Around it stood pillars engraved with spells forming a combined sealing jutsu that blocked access to non-Otsutsuki members.
Even those with the medium couldn't channel chakra into it unless they were of the clan.
However, this restriction didn't apply to Hinata in the original timeline, so it was nothing for Izayoi.
His chakra connected effortlessly, granting him full control over its powers.
"This pupil power... is insane!" Izayoi exclaimed. "What kind of secret technique could create such a miracle of quantity into quality? Is it also Yin-Yang Release?"
The giant Reincarnation Eye didn't provide chakra beads or Samsara Eye Chakra Mode. Its wielder couldn't enter that mode but could release a devastating purple beam.
That beam was what wiped out the Otsutsuki main family.
Aside from lacking the Chakra Mode and beads, the giant Reincarnation Eye had all the other Samsara Eye abilities.
And one basic ability was amplified to epic levels—
Gravity.
With enough chakra, it could push the moon to collide with Earth.
This alone gave it world-ending potential.
Even Izayoi's Samsara Eye, after the final fetal movement, couldn't move the moon.
"That's good news..." Izayoi smiled. "Even with my current strength, I can't do that, which means these eyes still have room to grow."
He then tested other abilities—like farsight and x-ray vision.
The Otsutsuki clan used this eye to observe the entire ninja world.
Izayoi wanted to compare its monitoring abilities to his own.
But as soon as he connected, he instantly cut the link.
"What an insane chakra drain... No wonder Toneri couldn't monitor the world. These props really have their limits."
Like the Six Paths tools, using the giant eye's powers cost chakra.
Unlike his personal eyes, which had no such restriction.
The farther and deeper the observation, the greater the chakra consumption.
Izayoi finally understood why Toneri didn't monitor the ninja world.
It wasn't unwillingness—it was inability.
Toneri hadn't entered his full growth phase. His chakra levels were only slightly better than Naruto's pre-Kurama-half state.
He could access the giant Reincarnation Eye's powers—but not for long.
Besides gravity manipulation, the rest of the eye's abilities were less powerful and flexible than Izayoi's own.
In the end, it was still just a tool—a synthesized ninja weapon.
But...
"What enviable eye power."
Staring at the golden patterns, Izayoi murmured, "If only I could transplant its eye power into my own..."
"The Mangekyo Sharingan can fuse eye powers... I wonder if the Uchiha method would work on the Reincarnation Eye?"
"I'll first learn the thousand-year-old text, decipher the fusion method, then collect Uchiha eye-fusion knowledge... then test if it's possible."
But just as he was thinking that, Izayoi's expression shifted.
He looked down.
His gaze pierced the ancestral hall and artificial sun to focus on the moon below.
He had just sensed a new chakra there.
The Samsara Eye's perspective immediately caught a flying chakra signature.
The Second Tsuchikage's figure was exposed.
Seeing this, Izayoi blinked in surprise. "I just got here… and they already found the space channel? Is this coincidence… or something even I don't know?"
