After a show of brotherly affection, Zou Hyuga patted Toneri's hair as a gesture of respect.
Hamura nodded in satisfaction. His spirit body would not last much longer, and seeing this scene gave him some comfort.
After a brief pause, Hamura slowly said, "It's about time I told you what the Tenseigan is used for. Toneri, you should know about its ability to monitor the Shinobi World."
Toneri nodded gently. For as long as he could remember, his clan had used the Tenseigan to monitor the Shinobi World, waiting for an opportunity to destroy this failed world.
Though that behavior now seemed somewhat foolish, there was no denying that the Tenseigan could monitor most of the Shinobi World and provide corresponding alerts based on chakra fluctuations.
Zou Hyuga also put on a look of sudden understanding.
At that moment, Hamura's expression shifted slightly, turning solemn. "The Tenseigan can monitor the Shinobi World, but that wasn't why it was created. It was created to monitor the stars."
"Not to monitor the Shinobi World, but the stars?" Toneri found that somewhat difficult to take in.
Zou Hyuga's thoughts went further. If even he could guess at these things, Hagoromo and Hamura, who had sealed Kaguya, could not possibly have failed to question why their immensely powerful mother had appeared in the Shinobi World.
If their mother Kaguya had come from the stars, then somewhere among those stars existed a race as powerful as she was.
The God Tree had been planted to produce a Chakra Fruit, so members of that race would inevitably come to harvest it.
To defeat the enemies among the stars, Hagoromo and Hamura had likely begun preparing a response a thousand years ago. The Sage of Six Paths had nurtured his sons' reincarnations, while Hamura had nurtured Toneri.
