Memories unfolded before Shinsei. Otsutsuki Kaguya's memories were extremely complex, and Shinsei quickly browsed through them while manipulating his mental power to delete them.
These memories do not include Otsutsuki Kaguya's experiences before that, but only from the time she fell into this world.
Soon, Shinsei saw that the emperor of the Land of Ancestors had brought Otsutsuki Kaguya to a simple palace.
Because Otsutsuki Kaguya's appearance was so different from others, their marriage naturally met with opposition from everyone.
Shinsei watched as Otsutsuki Kaguya transformed from a weak woman into a ruthless and decisive one.
Numerous dissenting voices were forcefully suppressed by her.
Soon, with Otsutsuki Kaguya's help, the Land of Ancestors successfully destroyed the surrounding countries and unified the entire human settlement area.
However, her actions backfired. Some people claiming to be immortals approached Otsutsuki Kaguya.
These people were radiating white light, like gods descending to earth. When Shinsei saw this, he was reminded of his own Sage Mode, which was indeed similar to these people's.
These people, who called themselves immortals, possessed immense strength and incredible speed. Soon, they were engaged in battle with Otsutsuki Kaguya.
Surprisingly, these self-proclaimed immortals possessed strength far exceeding that of current ninjas, with the strongest among them reaching a level comparable to Shinsei.
Although Otsutsuki Kaguya possessed immense Chakra and incredible Ninjutsu, she seemed to lack combat experience.
Once someone figured out their tactics, the situation was quickly turned around by the other side.
Outnumbered and outmatched, Otsutsuki Kaguya was forced to flee.
Faced with Otsutsuki Kaguya's strange Ninjutsu, the sages couldn't stop her, allowing her to escape successfully.
Next, Otsutsuki Kaguya took out a seed from her person and planted it on a patch of earth.
The seed successfully grew into God Tree. Otsutsuki Kaguya ate the fruit of the God Tree, awakened the Rinne Sharingan, and became incredibly powerful.
Kaguya then confronted the group of self-proclaimed sages, defeated and killed them one by one, and absorbed their Chakra and souls.
Many of those who claimed to be gods died at the hands of Otsutsuki Kaguya.
Upon seeing this, Shinsei finally understood why the Mangekyō Sharingan could activate Susanoo —it was because it absorbed the memories and Chakra of these people.
These immortals and deities were already very powerful; if Otsutsuki Kaguya hadn't become so incredibly powerful after eating the fruit of the God Tree, they would never have perished.
Shinsei finally understood why Ryūchi Cave was going to such lengths to target him because of his Sage Mode; the root cause was that these Sages were too arrogant.
Shinsei witnessed them treating the animal spirits like servants, frequently beating and scolding them, and killing them at the slightest displeasure. The sacred lands of those spirits were filled with the corpses of various animals, as they treated these animal spirits entirely as food.
However, all these powerful immortals had their sacred grounds breached by Otsutsuki Kaguya, who killed them all. No wonder there were no human immortals afterward; they were wiped out by Otsutsuki Kaguya.
Later, Otsutsuki Kaguya became pregnant and gave birth to Hagoromo Otsutsuki and Hamura Otsutsuki.
(This uses the manga's setting: In the manga, Otsutsuki Kaguya first ate the God Tree Fruit, then quelled the war, then gave birth to a child, and finally became greedy, activating the Infinite Tsukuyomi; while in the anime, she eats the fruit, uses the Infinite Tsukuyomi quell the war, gives birth to another child, and then becomes greedy.)
Later, as the two children grew up, they began to rebel against their mother.
Hagoromo Otsutsuki and Hamura Otsutsuki joined forces to seal their mother into the moon.
Shinsei was also a bit overwhelmed by this. He could clearly sense that Otsutsuki Kaguya was actually more worried about the dangers from the stars.
However, this woman clearly has some mental issues. She turned humans into White Zetsu in order to expand her military strength, but no matter how many White Zetsu there are, they are of no use in high-level combat.
In addition, he discovered that Otsutsuki Kaguya's combat level was probably not much stronger than that of an ordinary person.
If Shinsei had that much Chakra and skill, he would have already overwhelmed Hagoromo Otsutsuki and Hamura Otsutsuki.
Otsutsuki Kaguya fought her son for months, successfully turning the entire world into a massive battlefield. Countless humans perished in this war, with only a few surviving.
Indeed, the fighting skills of Hamura Otsutsuki and Hagoromo Otsutsuki continued to improve during the battle, growing stronger with each fight, and ultimately successfully sealing Otsutsuki Kaguya away.
No wonder Naruto and Sasuke were able to join forces later to seal Otsutsuki Kaguya once again.
Aside from the fact that Naruto and Sasuke are the reincarnations of Hagoromo Otsutsuki, which might have made Otsutsuki Kaguya hold back, the bigger reason stemmed from her poor combat skills.
Otsutsuki Kaguya's memories brought a tremendous shock to those who were also within the Mental Network.
They never imagined that the legendary Sage of Six Paths actually existed. The earth-shattering battle scenes were far beyond what modern ninjas could comprehend; they were simply not on the same level.
Shinsei felt that his Mental Network was somewhat unstable. Everyone was mentally confused by these memories, and for a while, they started chatting amongst themselves.
Enraged, Tsunade yelled in the Mental Network, "Shut up, all of you!"
That's when things started to improve.
Once the Mental Network stabilized again, Shinsei continued to erase these memories, and everyone gradually recovered from the shock, their mental frequencies returning to normal.
He quickly deleted these memories and then added details to the Ten-Tails ' memories to make them look richer and more realistic.
Suddenly, the memories that had just been deleted reappeared in the Ten-Tails ' consciousness.
Shinsei's perspective shifts back to the emperor of the Land of Ancestors from the beginning.
The perspective shifted again, Shinsei felt himself detach from Otsutsuki Kaguya's body, seeing a strange yet beautiful face.
The woman had pale, yet radiant skin, and bright, Byakugan that held a hint of curiosity.
She asked slowly, "Who are you? Why did you erase my memories?"
Shinsei felt a chill run down his spine; the image from his memory had suddenly come to life!
At that moment, Shinsei suddenly realized that this must be Otsutsuki Kaguya's true will!
Fortunately, he had been mentally prepared beforehand, and he guessed that the Ten-Tails should contain the true will of Otsutsuki Kaguya.
Otherwise, it would be difficult to explain why Otsutsuki Kaguya was sealed in the moon, was born inside Madara Uchiha's body.
Shinsei tried his best to calm himself down, not showing any panic, but instead asked with a hint of surprise:
"Are you my ancestor, Otsutsuki Kaguya? I am your descendant, and I have come here specifically to rescue you!"
Otsutsuki Kaguya looked at Shinsei and nodded:
"Your Chakra does indeed originate from my descendants, but why does your Chakra contain that repulsive scent of sages?"
