Mount Myōboku, Shikkotsu Forest, and Ryūchi Cave are the three great places in the ninja world where Sage Mode can be learned. The concentration of natural energy there is unmatched anywhere else.
Having absorbed natural energy from the Gelel Stone, he could easily sense the locations of these three places. Since Mount Myōboku was the only one of the three not to have a summoning contract with him, Neji soon arrived there.
Mount Myōboku. A crowd of toads watched Neji, who suddenly pierced through space to arrive, with great curiosity. To reach Mount Myōboku, one either had to find a guide or sign a summoning contract with one of its toads. They had never seen anyone arrive by interdimensional travel before.
Neji scanned his surroundings, then disappeared into Yomotsu Hirasaka again, heading for the Great Toad Sage's residence.
Sensing Neji's arrival, an ancient toad wearing a doctor's hat, dozing in his seat, opened his eyes slightly. With a knowing look at Neji, he spoke leisurely, "A long time ago, I had a dream."
Neji knew this was the Great Toad Sage's precognitive ability, so he didn't interrupt and listened quietly.
"I dreamed a person with extremely powerful ocular abilities would come to me to ask about some past events."
"How boring."
Expecting something earth-shattering, he was only told this piece of news. His expression darkened for a moment. "So the Great Toad Sage likes to tease people too?"
"Haha…" Unlike Neji's grim face, the Great Toad Sage chuckled softly. He pushed a memory stone in front of him towards Neji and said calmly, "It's been so long, I've almost forgotten. But this memory stone will tell you everything you want to know."
In Neji's eyes, the memory stone's images began to cycle, playing back everything that had happened after he left.
…
Still in the shrine in the Land of Ancestors, not long after Neji left, Kaguya successfully gave birth to twin babies. To avoid affecting the future birth of Neji, Kaguya named them Ōtsutsuki Hagoromo and Ōtsutsuki Hamura.
These two children were naturally more powerful than ordinary people, even without using Chakra.
They were born with a pair of horns. Hagoromo and Hamura also inherited their parents' Byakugan. However, compared to Hamura, Hagoromo inherited the Sage Body of both Neji and Kaguya.
The two children often gathered to discuss their father. Their mother told them he was a very powerful person, but she refused to reveal his identity.
However, even Kaguya rarely spent time with the two children. Hagoromo and Hamura spent less time with Kaguya each day than they did eating. Most of the time, Kaguya stood silently beneath the Divine Tree. The responsibility of caring for the two children fell to Aino.
This meant that if the two wanted to find Kaguya, going to the Divine Tree was undoubtedly the quickest way.
One day, while Kaguya was away, Hagoromo and Hamura used genjutsu to control Aino, wanting to learn about Neji from her. Just then, Kaguya returned. Fearing this would affect Neji's birth, she severely disciplined Hagoromo and Hamura.
After being disciplined by Kaguya, Hagoromo's long-repressed resentment and confusion towards Neji finally exploded. After saying some disrespectful things about Neji, Kaguya, unable to bear her son's insults towards Neji, instinctively struck him.
This only worsened Hagoromo's already negative feelings towards Neji. He didn't understand why his mother was defending his father so fiercely, calling him a bastard who abandoned his wife and son and ran off somewhere.
He inadvertently came to the place where Neji had fought the Shinigami. His mother had told him that the series of贯通 mountains were the result of his father casually waving his hand. Overwhelmed by uncontrollable rage, his emotions amplified to their peak, and his Byakugan transformed into Three Tomoe Sharingan.
Why would a father with such immense power leave him and his mother? The young Hagoromo couldn't comprehend it.
Time passed quickly. Under the tutelage of Kaguya, the progenitor of Chakra, the two intelligent and talented children soon reached Six Paths level. Hagoromo, under certain circumstances, even awakened the Rinnegan, although there was still a gap compared to Gods like Evil God and Shinigami.
Before long, the two children became independent. Setting aside Hamura, the elder Hagoromo even found a girlfriend named Hane, a girl who was very pleasant to look at.
However, a change occurred during this period. In the past few days, Kaguya had been acting unusually. She stayed nowhere but home, completely dedicated to fulfilling her responsibilities as a mother, constantly warning the two brothers about taboos such as the Box of Celestial Generals and the Mask of the Shinigami, and so on.
At the same time, she taught the two brothers an extremely powerful sealing jutsu that utilized ocular power—Six Paths: Chibaku Tensei!
The brothers didn't understand why their mother was doing this, but they were happy to be able to spend so much time with her.
Until one day, Kaguya took the two children on a long journey, far away from the Divine Tree.
"Hagoromo, Hamura… seal me with Six Paths: Chibaku Tensei."
Kaguya's sudden command stunned the two brothers. The pain of a mother asking to be sealed by her sons was something no one could understand.
How could the two brothers possibly do such a thing?
Although Kaguya had rarely spent time with them, there was no denying she was their mother. She had raised them herself in their father's absence. How could they possibly attack her?
The two brothers retreated in unison, wanting to escape this place. However, Kaguya used her ocular power to restrain them, gently explaining the reason.
"Hagoromo, Hamura, I am the guardian of the Divine Tree. When I consumed the Chakra fruit, the Divine Tree and I became one. The Divine Tree is feeding on the life force of this planet and slowly destroying the world. But if I am sealed, everything can be resolved."
Before Kaguya's intentions could be conveyed to the two brothers, the Divine Tree, which was one with her, sensed them. The Ten-Tails appeared in the ninja world for the first time, to stop Kaguya.
"Hagoromo, Hamura, act!"
Kaguya's cry finally brought the two children back to reality. After a fierce internal struggle, the two brothers ultimately cast Six Paths: Chibaku Tensei on Kaguya. As the earth beneath their feet slowly covered Kaguya, accompanied by her reluctant gaze and repeated words of caution, she finally turned into a stone sphere that flew into the sky.
Losing Kaguya's power, the Ten-Tails stopped moving. Hagoromo absorbed it into his body, and its body was sealed on the moon.
Hamura, however, worried about his mother and settled on the moon.
