1 Mach...in other words, one times the speed of sound. When the human body is exposed to the air, its body-surface temperature reaches several dozen degrees, just like taking a hot bath.
At twice the speed of sound...the temperature of the body's surface rises to 100 degrees. The body gets scalded and boiled.
That was precisely why Susanoo existed.
The acceleration of the left eye could continue increasing from one times the speed of sound.
It could also resist the heat barrier formed when the body broke through the Sound Barrier.
Indeed.
The Second Stage, third stage, and Fourth Stage would all allow the user to move rapidly, running at speeds that would otherwise be unimaginable.
But although the First Stage Rib Susanoo had slightly lower defensive power, it could effectively follow the original body's movements.
Uchiha Izumi...no, any Susanoo wielder.
could move rapidly while maintaining the First Stage Susanoo, without separating from Susanoo.
This method of combined use allowed Uchiha Izumi to evade and resist most Ninjutsu, Taijutsu, and Genjutsu.
Its only weakness.
was that Uchiha Izumi could not maintain Susanoo for 24 hours.
However, after being set once, the accelerated state could become half-passive.
Similar to Uchiha Obito's Kamui intangibility.
Uchiha Izumi could consciously enter this half-passive, half-active accelerated state.
Next.
Uchiha Izumi continued developing the abilities of her left eye and right eye.
A ninja's abilities truly underwent earth-shaking changes between different ranks and levels.
A ninja.
His stages as an Academy Student, Genin, Chunin, Special Jonin, Jonin, and Kage.
These several stages.
had vastly different physical qualities.
Academy Students, Genin, and Chunin could be crushed to death if a several-meter-tall boulder, large enough to cover a person, fell on them.
Just like Uchiha Obito at thirteen, when he carried out the mission at Kannabi Bridge.
A
