The Sharingan's genjutsu is different from other genjutsu. This genjutsu is purely innate to the eyes, requiring no hand seals, just direct eye contact with the opponent!
In the original work, only two people brought this ability to its near-absolute extreme: one was Uchiha Madara, and the other was Uchiha Itachi.
Uchiha Itachi needs no further introduction; his mastery of genjutsu is likely even more terrifying than Uchiha Shisui, whose Mangekyo Sharingan ability was 'Kotoamatsukami'!
As for Uchiha Madara, he fully utilized the Sharingan's effects to the extreme. During the Fourth Shinobi World War, when he single-handedly fought the Shinobi Alliance, he used only taijutsu and his Sharingan to utterly overwhelm the alliance, leaving them lost and disoriented. Those who made eye contact with him were basically immobilized and slaughtered like chickens!
Although Uchiha Kei couldn't reach the level of these two, his genjutsu was by no means bad.
With a surge of mental energy, Uchiha Kei's genjutsu was fully unleashed. Just as Gari was about to strike him, Gari suddenly experienced a fatal moment of disorientation!
Uchiha Kei naturally wouldn't let this opportunity slip by. With a forceful grip of his left arm, he seized Gari's chakra-infused hand, much like how Uchiha Itachi dealt with Sasuke's Chidori, firmly grasping it.
Then, Uchiha Kei yanked his hand towards the ground, and at the same time, Uchiha Kei's ninja sword slashed towards Gari's head!
In this moment of extreme crisis, Gari displayed the essential qualities of a powerful ninja. Within an extremely short period, Gari regained his clarity.
Although his right hand was caught and his attack trajectory altered, he still had his left hand!
Almost instantly, his left hand erupted with terrifying chakra light, and then, fearlessly, he struck towards Uchiha Kei's chest.
There is a significant commonality among ninjas, or perhaps among all humans: when pushed to the brink, they will choose an ultimate exchange, a one-for-one.
Uchiha Kei sensed this guy's intention. Gari's decisiveness forced Uchiha Kei to release his left hand and leap backward.
Uchiha Kei greatly valued his life; he neither wanted nor was willing to fail at this point, when victory was within sight.
However, Uchiha Kei was not a person with infinite patience. Although forced to disengage, Uchiha Kei twisted the blade at that very moment.
The ninja sword, imbued with Uchiha Kei's chakra, directly targeted Gari's outstretched left hand. However, after striking the hand, Uchiha Kei quickly withdrew and released control of the ninja sword.
This damn guy had sent his left hand directly at him, and his left hand still contained his Explosion Release!
"BOOM!"
The immense roar was almost painful to Uchiha Kei's ears. Dust filled the air, and debris flew everywhere. Uchiha Kei could only retreat a bit further.
But just then, Uchiha Kei suddenly noticed Gari getting up and struggling to retreat rapidly.
Trying to escape?
Uchiha Kei sneered. He immediately pulled out a kunai and pursued, the smoke posing no obstacle to Uchiha Kei.
His eyes could clearly see Gari's chakra, and he could even clearly see Gari's subtle movements.
Gari was in great discomfort. He had to admit that he had underestimated the Uchiha Clan, or rather, underestimated the power of the Sharingan.
The Uchiha Kei before him was not old, appearing to be only thirteen or fourteen years old, yet the intensity of his Sharingan made Gari's scalp tingle.
He had heard that one couldn't look directly into the eyes of an Uchiha during a fight. He had also heard that this kid's Sharingan was very strong, seemingly reaching the Three Tomoe level.
But he hadn't paid much attention until he saw it with his own eyes. He wasn't unfamiliar with Uchiha members; he had dealt with both those who had awakened their Sharingan and those who hadn't.
Therefore, his impression of the Uchiha Clan was more of a group of mythical figures. However, he didn't let his guard down. His fighting style and rhythm were all according to his own plan.
Moreover, he had been intentionally or unintentionally avoiding Uchiha Kei's eyes. He never expected that just as he seized an opportunity against the Uchiha imp, he himself would present an opportunity to the Uchiha imp.
Completely unprepared, without any abnormal Chakra fluctuations, he was directly caught in a Genjutsu!
Even though the Genjutsu's effect on him lasted less than a second, that mere moment of less than a second brought him immense danger.
Even as he regained his senses, he had already made a decision, but his movements were still seen through by the Sharingan!
By exchanging life for life, Gari managed to save his own life, but he lost his left hand.
At this moment, Gari had to stop the bleeding while also thinking about how to deal with this kid. If he didn't stop the bleeding, he would definitely die from excessive blood loss. But if he didn't deal with this kid, their troubles would only grow.
"Damn it! So fast?"
Just then, Gari suddenly felt a terrifying aura appear behind him.
But at this moment, Gari seemed a bit slow. He couldn't react in time before a Kunai pierced his heart from his back!
Gari's face turned pale, and then he slowly fell to the ground, looking as if he were completely dead.
Uchiha Kei, standing behind him, tilted his head, a hint of mockery appearing on his face.
"Is this all you've got? The gap between you and Kitsuchi is truly vast." Uchiha Kei's voice sounded somewhat flippant, more like a sense of relaxation.
But just then, a figure suddenly burst out. A terrifying Chakra gathered in his hand, and he fiercely struck towards Uchiha Kei's location!
"What?"
Uchiha Kei seemed to panic, as if he had completely not expected such a situation to occur!
Gari remained silent. The Ninjutsu he unleashed by concentrating all his Chakra was incredibly terrifying.
Uchiha Kei seemed frozen in place, making no Evasive Action. That look of terror immediately made Gari extremely vigilant. As expected, when his fist landed on Uchiha Kei, that strange sensation told him it was a clone!
But Gari didn't give up. He forcibly turned around, Chakra continuously gathering in his right hand, and Gari threw another punch.
However, this time he really couldn't hit Uchiha Kei. Forcing himself to turn, coupled with the bleeding from his severed left hand, it was already incredible that he could throw such a punch!
Half a meter, thirty centimeters, ten centimeters. Just as his fist was about to hit Uchiha Kei, Uchiha Kei suddenly made a subtle twist. At the same time, his Kunai smoothly pierced Gari's chest!
The ten-centimeter-long Kunai was diagonally inserted into Gari's right chest. Uchiha Kei used immense force. The sharp Kunai broke Gari's ribs. Except for the hilt, the rest had already disappeared into Gari's chest.
Blood continuously flowed from the wound, dripping onto the ground, moistening the nearby soil.
"Did you really think I couldn't see what you were doing? In these eyes, you have no secrets."
Uchiha Kei's voice was exceptionally cold. His pair of crimson eyes stared intently at Gari, and then Uchiha Kei fiercely twisted the Kunai in his hand.
Instantly, a piercing scream echoed throughout the wilderness!
