Clang!
After the kunai stabbed Mokgetsu's arm, before anyone had a chance to see if his arm was injured, they saw the sharp end of the kunai break off and fall to the ground.
"This defense is too strong!" Obito stared at Mokgetsu's unchanged arm with wide eyes, speaking in disbelief.
He thought that if this could cover the whole body, it would be incredibly safe in battle, with no need to worry about getting hurt.
Might Guy understood why Mokgetsu insisted he must learn this Secret Technique.
If he mastered this Secret Technique, he wouldn't need to learn weapons in the future; he could confront others barehanded using Armament Haki.
Kakashi's eyes flickered, remembering Mokgetsu's initial claim of simultaneously enhancing defense and attack; he was curious about the upcoming attack demonstration.
However, Mokgetsu didn't end the defense demonstration there. He asked the students to step back, then said to Shisui:
"Use all your strength to attack me with Impatiens Claw Red."
If it's about being awe-inspiring, then it must be done by directly confronting the Ninjutsu.
"Fire Release: Impatiens Claw Red!"
Since Mokgetsu asked for full power, Shisui didn't use the single-hand variant with a kunai; instead, he completed the full hand seals and launched numerous shuriken.
The rapidly advancing shurikens touched the flames released by Shisui, instantly turning into dense small fireballs.
"At this age, he can use a Ninjutsu of this level!" Kakashi was deeply surprised at the power of the Fire Release exhibited by Shisui.
The first time Kakashi saw Shisui was during an evening walk with Obito and Nohara Rin, where Obito mentioned that Shisui was a genius greater than himself.
Previously, Kakashi hadn't taken Obito's words to heart, since they came from Obito.
But now, after watching Shisui perform the Fire Release, whether he could surpass him was hard to say, yet he was undoubtedly a strong genius.
As the fireballs were about to hit, Mokgetsu immediately unleashed his Chakra to cover his entire body with Armament Haki, turning his whole body pitch black.
Rumble!!
The small fireballs continuously struck Mokgetsu, causing bursts of explosions, and the violent firelight completely obscured Mokgetsu's figure.
Obito tried his best to widen his eyes, hoping to see through the firelight to glimpse Mokgetsu inside, but without the Sharingan, he could only make out a vague silhouette amidst the flames.
Like swatting away mosquitoes, Mokgetsu waved his hand, generating a powerful gust that blew away the smoke from the explosions, revealing his unharmed body.
"He can actually withstand Fire Release Ninjutsu head-on so effortlessly!" Kakashi was surprised as he saw Mokgetsu's pitch-black substance remained unchanged.
Kakashi had known all along that Mokgetsu could withstand this; after all, if Mokgetsu couldn't, why would he allow Shisui to go all out?
But in Kakashi's imagination, Mokgetsu's body should have had some changes, like leaving some marks on the black substance.
However, in reality, Mokgetsu's body showed no changes whatsoever, not even any damage to his clothes when he dismissed the Armament Haki.
Knowing this technique had sharp shurikens combined with the high heat of the flames, Kakashi thought that if this Ninjutsu hit a normal person, it could blast them apart.
"So cool, this is the Ninjutsu I want to learn!" Obito got excited instantly seeing the undamaged Mokgetsu surrounded by fallen shurikens, sparking a fantasy in his mind.
He and Nohara Rin were on a mission, and when Nohara Rin was ambushed, he activated Armament Haki to shield her, then effortlessly asked if she was hurt.
"Rin would definitely be impressed by me." Obito thought, imagining Nohara Rin's admiring expression, with a silly smile appeared on his face.
"This is the defensive power of Armament Haki. If your Haki is strong enough, even Ninjutsu can be blocked head-on," Mokgetsu said with a smile.
"Of course, until you reach a certain level, don't use full-body Armament like me to withstand Ninjutsu. I'm doing this because my strength far exceeds yours," Mokgetsu reminded them.
Except for special situations like the Eight Gates, Mokgetsu generally didn't recommend full-body Armament.
Mastering it to its peak in a focused area is the correct way to develop Armament.
"Everyone, come behind me and keep some distance. I'm going to perform an attack now," Mokgetsu continued.
He consumed Chakra to generate Armament Haki, then began to concentrate the Haki onto his fist, preparing for a simple straightforward punch.
All four disciples focused intently on Mokgetsu's fist, curious about how powerful an attack boosted by Armament Haki could be.
