Actually, Mikoto had seen Kazuki's Chakra suddenly surge before. After all, her house was next to Kazuki's, and she often stayed at Kazuki's place.
Kazuki usually hid his strength, and she didn't know his true power, but sometimes Kazuki would "accidentally" unleash his real strength. Therefore, Mikoto was quite used to such occurrences.
It was just that no previous surge seemed as intense as this one.
Mikoto was actually very familiar with Kazuki's current state. This feeling was like when she had undergone the Giant Tenseigan's baptism, experiencing a bloodline atavism.
What made Mikoto curious was that Kazuki's bloodline was, at a minimum, already at the level of the Sage of Six Paths.
So, if Kazuki underwent another bloodline atavism, how powerful would he become?
Would it be the level of the Chakra Ancestor, the Rabbit Goddess, the Sage of Six Paths's mother, Kaguya?
But why did she feel that Kazuki might even surpass Kaguya?
However, as Orochimaru said, this was somewhat unscientific.
Logically, even if Kazuki were to undergo bloodline atavism, he shouldn't repeatedly do so, with his strength continuously skyrocketing.
But if it happened to Kazuki, then what?
The Ninja World itself contained many things that defied everyone's imagination.
Aside from research fanatics like Orochimaru and Tobirama, most people wouldn't be puzzled by how things turned out this way.
The Ninja World had its own realities.
Everyone knew Kazuki had secrets, but could they demand that he reveal the truth?
It was enough to know that he was on their side.

"Brother, did you feel that aura just now?" Hamura asked Hagoromo in the Pure Land, his voice filled with worry.
Hagoromo looked toward the deep sky and said, "Yes, that was Kazuki's aura. His aura is becoming more and more like mother's, even surpassing mother's."
Hagoromo wasn't too worried about Kazuki's strength. Kazuki clearly understood the specific situation of the Ninja World. They all wanted the Ninja World to continue to develop.
As for Kazuki's situation, it must be a bloodline atavism, right?
From what Sasuke, the future Indra Chakra reincarnation, said, Kazuki and his companions would go into space to fight the Ōtsutsuki clan in the future.
Hagoromo felt that Kazuki and he likely shared a similar mission.
When Kaguya wanted to destroy the Ninja World, he and Hamura were born, and for this planet, they embarked on the path of fighting Kaguya.
When the Ōtsutsuki were about to descend upon the Ninja World, the Ninja World gave birth to a being like Kazuki. This was an existence specifically born to fight the Ōtsutsuki, so some special circumstances seemed inevitable.
The more powerful he became, the more Hagoromo believed in the existence of fate.
"Perhaps he obtained the power of our grandfather?"
Hagoromo first glanced at the location of the nine Tailed Beasts, then looked at the seal on the moon, confirming his mother was safe.
Ever since he learned that Kazuki could extract others' Chakra to make Chakra pills, he had become somewhat nervous.
He and Hamura were crucial to the Ninja World, so he didn't need to worry about Kazuki destroying them for power. However, their mother, Kaguya, was a huge hidden danger to the Ninja World. It seemed natural for Kazuki to eliminate Kaguya.
However, Hagoromo did not want to eliminate Kaguya. After all, Kaguya was his mother.
What he hoped for was that Kaguya would reflect on herself within the seal, realizing how wrong her actions were and that they were in the right.
Originally, Hagoromo hoped that after he got stronger, he could then reason with his mother. He believed his strength was sufficient to deal with his mothe. Nnot just himself, but even Hamura could probably deal with Kaguya now.
After all, the power system they were currently practicing was specifically for dealing with Kaguya, and of course, also for resisting the future Ōtsutsuki. They had always considered the Ōtsutsuki their imaginary enemy.
Although Hagoromo and Hamura also bore the Ōtsutsuki name, they had never met other Ōtsutsuki, so they could only use their mother's standards as their imaginary enemy.
Considering that their mother was still around and was very wary of the Ōtsutsuki from outside the world, they decided to set the standard as stronger than Kaguya.
When they previously learned that there was another Ōtsutsuki in the Ninja World, Hagoromo and the others were startled.
Therefore, when Kazuki fought Isshiki, they followed to observe the battle between the two sides. If necessary, they wouldn't mind lending a hand.
What they didn't expect was that Kazuki's strength seemed to be even greater than imagined.
As for Isshiki, he was very powerful, but not as powerful as they had imagined. His raw power might not be comparable to Kaguya, who had Kekkei Mora, but in terms of combat skills, he was immeasurably more skilled than her.
Isshiki, unlike Kaguya, had learned the Ninja World's combat system, and the power he unleashed was definitely not much weaker than Kaguya.
This made Hagoromo even more convinced that the path he had chosen before was correct, and the Ninja World was also on the right track.
Hamura said worriedly, "But if this happens, it might alert the Ōtsutsuki in the starry sky. Mother told us before that they are very sensitive to the aura of their kin. Kazuki's aura has now spread throughout the entire Ninja World. I believe they cannot possibly not detect it."
Hagoromo's gaze was profound as he said, "I have already done my best to help him reduce his aura. If it really reaches beyond the starry sky, we cannot sit idly by. As of now, the stronger Kazuki's power, the greater the help to the Ninja World."
