Dark Cave.
Hiss, hiss!
Sensing that Hiruko's five senses had been extinguished, Kabuto's tail flicked out its tongue.
"The genjutsu is getting more and more terrifying. This is no longer simply disrupting chakra to make someone fall into an illusion. Is it a genjutsu that transmits chakra through sound and directly attacks the mind?"
Kabuto tried to use Forced Execution to erase the mind of the reanimated Hiruko and make the body attack on instinct, but found that it had no effect.
Based on his existing knowledge, he began to infer Tobitake Tonbo's abilities.
The mind and body could each refine chakra independently, but doing so would create an imbalance, making the separately refined chakra uncontrollable.
Abilities developed to control this kind of chakra were called Secret Techniques.
In other words, both the mind and body contained chakra, and Tobitake Tonbo's genjutsu directly disrupted the enemy's mental chakra.
"As expected of Tobitake Tonbo. He even found a way to disrupt the violent nature of mental chakra on its own. This level of mastery..."
Kabuto thought of Lord Orochimaru.
In certain fields, he too had reached the pinnacle.
He had surpassed the heights of the previous generation of shinobi.
Only people like him and Lord Orochimaru, who had delved deeply into the truth of ninjutsu, understood just how extraordinary such mastery was.
This meant that in Yin Release Nature Transformation, Tobitake Tonbo had already surpassed his predecessors by an enormous margin. Kabuto believed that even the legendary strongest genjutsu would be ineffective against him.
Just like Lord Orochimaru's research into Hashirama Cells, it could break through the limits of many people's imagination.
"However, I have already surpassed Lord Orochimaru. I won't let you have it so easy."
After understanding the activation mechanism of Tobitake Tonbo's ninjutsu, Kabuto rapidly formed hand seals.
