The Bringer-of-Darkness Technique was considered a separate system within Genjutsu.
Unlike visual Genjutsu, which affected an enemy's chakra through sight.
Nor was it like auditory types, which transmitted chakra through sound.
It was a large-scale Genjutsu that spread chakra through the air. Its process resembled the release of a ninjutsu, but its effect was Genjutsu.
So, integrating darkness into his own Genjutsu system was still somewhat difficult for Tobitake Tonbo.
At the very least, it was not something he could accomplish in a day or two.
Tobitake Tonbo had not devoted all his energy to it, either. He mainly spent a little time each day accumulating experience, intending to finish it only once he had built up enough.
His primary research now still lay in ordinary Genjutsu.
Such as visual types, auditory types...
And research into the Mind Reading Technique series.
Eight Fragrances of Fire, for example, was a specific application born from his research into auditory Genjutsu. It transmitted chakra through sound and affected the enemy's five senses.
"Ahhh, it hurts..."
Izuno Caicai landed hard on his backside, pain bringing tears to his eyes.
Looking at the pillar before him, he dearly wanted to destroy it with his clan's Secret Technique.
But when he saw Tobitake Tonbo practicing music nearby, he swallowed that urge.
Fuma Zhikun was the same. This kind of precise chakra control was simply too difficult.
At that moment, his center-parted hair and suspenders were both soaked with sweat.
From exhaustion.
"Hey, work harder. I think I'm starting to get the hang of it." Hana Inuzuka lifted both feet from the ground and slowly walked ninety degrees along the pillar.
The moment she finished speaking, she fell again.
Her face was full of excitement. This feeling was truly amazing.
It was not difficult at all!
