Part of the difference lay in their Chakra, of course, but even with equal amounts, the two techniques would probably be worlds apart in power.
The Hyuga Clan's Eight Trigrams Vacuum Palm barely scratched the surface of the Eighty Gods Vacuum Attack.
It was like comparing the Fire Release: Great Fireball Technique to Fire Style: Majestic Destroyer Flame. With too little Chakra, one could only use the Great Fireball Technique. But with enough Chakra, even if the same amount went into each technique, the Great Fireball Technique could not match Majestic Destroyer Flame's power.
Of course, that was only an example.
Then again, perhaps the Eight Trigrams Vacuum Palm was merely a severely diminished version of the Eighty Gods Vacuum Attack that Kaguya Otsutsuki had left with the Hyuga Clan.
The Hyuga Clan, unaware of any of this, was stunned all the same.
"Kaguya Otsutsuki... Could she really be one of them?!" The current head of the Hyuga Clan still had some contact with Hamura Otsutsuki's descendants on the moon.
Seeing what had happened, he took Kaguya for a member of the Ōtsutsuki Clan on the moon.
After all, Kaguya's Byakugan was hard to miss. The Hyuga Clan had noticed it long ago.
But they had made no rash moves.
Kaguya was one of Uchiha Yin's people, and everyone knew how fiercely he protected his own.
Offending Uchiha Yin would be a grave mistake.
Now they were even more grateful they had not acted rashly and offended Kaguya.
At her level of strength, Uchiha Yin probably would not even need to intervene.
The entire spectator area fell silent. Uchiha Yin had no choice but to step into the center of the arena.
"The joint Chunin Ninja Exams are over!"
"The winner is Kaguya Otsutsuki."
Only when Uchiha Yin announced it
