Madara recalled a long-buried memory and muttered to himself.
"Awakening the eyes relies on intense emotional fluctuations, which stimulate the brain to produce a special chakra that acts on the optic nerves and changes the eyes."
"If I remember correctly, that fluctuation originates in the frontal lobe, then travels to the cortex on either side of the calcarine fissure in the occipital lobe..."
Back then, the Uchiha Clan had thoroughly researched the principles behind awakening their eyes to cope with war.
Their leader at the time had envisioned every member of the clan awakening their eyes.
Then the Uchiha Clan would be unstoppable, with no one left to challenge them!
But that vision had remained nothing more than a vision to this day.
The human brain was simply too fragile.
Messing around like that could easily cost someone their head.
After roughly a hundred volunteers had died,

Now Madara intended to test it on himself and awaken his eye with this shortcut!
"My control over chakra is exceptionally precise, and my body has long since transcended ordinary human limits..."
"With Yin-Yang Release as a safeguard, there shouldn't be any problems."
Confident in his abilities, Madara wasn't afraid in the slightest.
(Are you kidding? I'm brave as hell!)

His black iris turned blood-red, and a single tomoe appeared to the sound effect of his eye awakening.
"Again!"
Madara thickened the bundle of chakra
