To avoid putting the Yamanaka Clan in a difficult position, Uchiha En secretly snuck in and, without anyone noticing, learned their secret Ninjutsu.
Uchiha En used the Yamanaka Clan's secret Ninjutsu to manipulate his mental energy and invade Urashiki's brain.
Although Urashiki's brain had complex Ninjutsu protecting it, Urashiki was already dead, and a single Ninjutsu couldn't stop Uchiha En.
Relying on the knowledge he had accumulated over the years and the Six Paths Sage Art-level Sealing Jutsu he learned from Uncle Sasuke, Uchiha En began to decipher the Ninjutsu in Urashiki's mind bit by bit.
According to the progress, it would take about two days to break it open.
Spending two days to decipher Urashiki's Ninjutsu and obtain the vast amount of precious knowledge stored in that brain was worth it, no matter how one looked at it.
Even faster than deciphering the Sealing Jutsu in Urashiki's brain was memorizing the structure of this turtle-shaped time-traveling machine.
Because the structure of this time-traveling machine was much simpler than Uchiha En had imagined.
Originally, Uchiha En planned to take three days to memorize its structure, but Nijo said that there were similar jutsu formulas in the Sealing Jutsu she remembered.
With a comparison, Nijo only took a little over a day to memorize everything.
Nijo remembered it and directly fed the memory back to Uchiha En, who then also remembered the turtle's structure.
However, the deciphering of Urashiki's brain protection Ninjutsu was much slower than expected, taking another two days to break.
This meant Uchiha En spent a full three days to completely decipher this Ninjutsu.
And without this Ninjutsu, Urashiki's brain was no longer defenseless against Uchiha En.
The memories stored within were fully displayed before Uchiha En's eyes.
Even after discarding most useless memories and retaining only key information, by the time Uchiha En had sorted through Urashiki's vast memories accumulated over a thousand years of life, it was already the next day.
As initially expected, Uchiha En obtained a Ninjutsu from the Ōtsutsuki Clan that condenses Chakra from Tailed Beasts and people into a pill-like form.
He also obtained Yomi Hirasaka, a Space-Time Ninjutsu that can traverse world barriers.
However, learning this Ninjutsu might be troublesome, and Uchiha En couldn't guarantee how long it would take him to master it.
In addition, there was the Ōtsutsuki Clan's technique for planting God Trees and converting them into Chakra Fruits.
According to Otsutsuki Urashiki's memories, the Ōtsutsuki Clan always brought Lesser Ten-Tails to different worlds.
Ōtsutsuki Urashiki's memories also showed that Ōtsutsuki Isshiki possessed a Lesser Ten-Tails.
This greatly surprised Uchiha En, as he hadn't found this Lesser Ten-Tails when he wiped out the Kara organization.
So Uchiha En immediately teleported to the ruins of the Kara organization to search for the Lesser Ten-Tails from Ōtsutsuki Urashiki's memories.
However, after searching all around, Uchiha En found no trace of the Lesser Ten-Tails.
But he did notice a large pit underground at the Kara organization's site.
The size of this pit was roughly the same as Nijo's volume when Uchiha En first created her.
This indicated that it was very likely where the Lesser Ten-Tails was stored.
But now the Lesser Ten-Tails was gone. Where did it go?
If it had escaped on its own, the Lesser Ten-Tails had no consciousness and only knew destruction, so news of its rampage should have spread long ago.
Therefore, Uchiha En speculated that this Lesser Ten-Tails was most likely taken away by someone.
Considering the current Ninja World, probably only that guy had the ability to take away the Lesser Ten-Tails.
Ōtsutsuki Takegami's figure appeared in Uchiha En's mind.
If it was indeed Ōtsutsuki Takegami who took the Lesser Ten-Tails, then things might be a bit troublesome.
So Uchiha En immediately found a nearby White Zetsu clone and had him relay his suspicions to Obito and Nagato, asking them to help investigate whether Ōtsutsuki Takegami had taken the Lesser Ten-Tails.
Afterward, Uchiha En returned to Konoha to continue organizing Ōtsutsuki Urashiki's memories, especially the intelligence concerning the Ōtsutsuki Clan.
Just as Uchiha En had speculated after watching Naruto, the Ōtsutsuki Clan was a powerful bloodline race from the depths of the universe. They were born with powerful Byakugan Eye power and physiques.
Relying on these innate advantages, the Ōtsutsuki ancestors slowly rose on the Ōtsutsuki Planet, eliminating other races and standing at the apex of the entire universe.
In the long years that followed, the Ōtsutsuki Clan members planted God Trees throughout the universe and gained superhuman power and longevity by eating the fruits of the God Trees, further evolving their bloodline to a higher level.
However, from Urashiki's memories, it seemed that the original God Trees were not as domineering as they are now; planting them wouldn't directly destroy a planet.
Although the God Trees also absorbed Natural Energy to grow, they wouldn't cause biological extinction.
Later, the ancestors of the Ōtsutsuki Clan, in order to gain even greater power and longevity, further improved the method of planting God Trees.
But soon, the surrounding planets were completely ravaged by the Ōtsutsuki Clan.
In order to obtain more Chakra, the Ōtsutsuki Clan members began to leave their own star system and travel to more distant planets in the universe, widely planting God Trees and harvesting Chakra.
The pioneers became increasingly powerful, and there even appeared a figure known as the God of the Otsutsuki Clan.
After the God of the Otsutsuki Clan fell, the stronger members of the Ōtsutsuki Clan divided the clan into Main Family and Branch Family, with the Main Family as the leadership.
However, this so-called Main Family and Branch Family was somewhat different from the Hyuga Clan's Main and Branch Families.
While called Main Family and Branch Family, it should actually be called 'Guardians and Protected' more appropriately.
The strength of the Protected was clearly stronger than the Guardians, because the Protected had consumed many God Tree fruits, and the more God Tree fruits eaten, the stronger one naturally became.
The Guardians, on the other hand, mostly played the role of tools for planting God Trees.
Many times, Guardians would feed themselves to the God Tree, because the God Tree would only grow rapidly and bear fruit after devouring a member of the Ōtsutsuki Clan.
And Guardians would not die after being devoured by the God Tree, because they had left their Karma in advance.
The Protected only needed to wait for the Karma to unfreeze, and the Guardian would revive again, following the Protected to the next world, repeating this cycle.
"What a troublesome race! But since the Ōtsutsuki Clan members always act in pairs, why are Ōtsutsuki Takegami and Ōtsutsuki Urashiki alone?" Uchiha En muttered to himself.
