"Shadow Clone Jutsu!" Seeing the Earth Flow Wall rise, Shisui immediately performed the Shadow Clone Jutsu to create a clone, then used Instant Body Jutsu to hide beside a big tree.
Since he didn't know what strategy Kakashi would use next, he decided to hide and observe the situation in secret first.
Then Shisui opened his Sharingan to enhance his insight.
The next moment, Kakashi jumped onto the Earth Flow Wall, looking down at Shisui's shadow clone.
Swish, swish, swish!!
Shisui's shadow clone quickly threw several shuriken at Kakashi to block his position, then rushed towards Kakashi with Instant Body.
Kakashi ran and jumped on the Earth Flow Wall, dodging the incoming shuriken, and eventually collided with the advancing Shisui.
The two quickly exchanged dozens of blows, and Shisui's shadow clone soon fell into a disadvantage, intending to retreat. Although a shadow clone is a physical clone, it will dissipate once it suffers a certain amount of damage.
Just then, another Kakashi suddenly emerged from the ground and grabbed Shisui's shadow clone's leg. This sudden change allowed Kakashi to land a heavy punch, directly dispersing the shadow clone into smoke.
"Fire Release: Impatiens Fire Jutsu!"
At the moment Kakashi emerged from the ground, dense fireballs shot from the tree towards him.
Boom boom!!
A multitude of small fireballs engulfed Kakashi on the ground, dissipating along with Shisui's shadow clone.
"Lighting Release: Pseudo-Darkness!"
Another Kakashi drilled out from the underground, forming hand seals and releasing a thunderous Thunder Spear.
"Fire Release: Great Fireball Jutsu!"
From atop the tree, Shisui formed hand seals again, releasing a massive fireball towards Kakashi.
Crash!!
The razor-sharp Thunder Spear shattered the gigantic fireball like bursting a balloon, then cleaved through the tree where Shisui was, breaking it in half.
Kakashi did not show a triumphant smile, as at the last moment, a figure flashed out, and he hastily sidestepped to dodge a kunai thrown at him.
Swoosh!
Just as Shisui was about to continue his attack, a yellow lightning suddenly burst out from behind the tree, the fierce Thunder Slash about to strike Shisui.
Not only was Shisui unfazed by the attack, but he also smiled.
Crash!!
Shisui, who was struck by the Thunder Slash, suddenly exploded, and the intense firelight engulfed both figures.
"Kakashi, that guy, constantly uses shadow clones to deceive, finally got tricked himself. But he probably won't be killed by the explosion," Obito commented as he spat towards Kakashi's direction, eagerly watching the smoke with the impulse to activate his Sharingan.
"There's no way my best friend would fall to such ninja tools as an Explosive Tag!" Might Guy expressed complete confidence in Kakashi.
The smoke quickly faded away, revealing no bodies inside, only the charred ground from the explosive tag. Both of them were shadow clones.
Whoosh!
Just as the audience was still amazed by the battle situation, Shisui's figure suddenly rushed out, while Kakashi instantly locked onto Shisui, seeing the blood-red Sharingan in his eyes.
"Illusion Instant Body Jutsu!"
At the moment of locking eyes with Kakashi, Shisui activated his Sharingan and simultaneously formed hand seals to use ninjutsu.
Instantly, more than twenty Shisuis appeared on the field, surrounding Kakashi.
"Multiple Shadow Clones?"
Kakashi immediately thought of a ninjutsu, but shook his head shortly after. Though this technique isn't hard to learn, it's impossible for Shisui to split into more than twenty clones using chakra, unless they are weak clones, which are useless other than wasting chakra.
Swish!
Kakashi immediately threw a shuriken at one of the Shisuis, surprised to find the shuriken passed through Shisui's body without causing him to disappear or get hurt.
"No physical clones?" Kakashi felt doubtful, thinking it's even more useless.
Before Kakashi could think deeply, several Shisuis rushed forward and engaged in melee with Kakashi, who was surprised to find these Shisuis were physical.
Kakashi maximized the Breath of Thunder, bursting out at high speed to escape the encirclement, feeling extreme puzzlement.
The confused Kakashi randomly threw a ninja tool at one Shisui again, but it passed through like an illusion once more.
Kakashi pondered some speculation, pushing the Breath of Thunder to its peak. Through Kakashi's perception, his body seemed to become transparent.
This was the result of Kakashi's month-long hellish training, not quite the real Transparent World, but allowing him to control it himself without relying on luck.
The sight shocked Kakashi; his chakra was in chaos, having unconsciously fallen into Shisui's genjutsu.
"I get it now; no wonder it's so peculiar." Kakashi realized what was going on with Shisui's clones.
Those unstrikeable Shisuis were neither shadow clones nor ordinary ones, but rather the effect of genjutsu.
As Kakashi calmed his chakra, the number of Shisuis on the field drastically reduced, leaving only three.
Perceiving Kakashi breaking free from the genjutsu, Shisui secretly thought things weren't looking good; this technique, which he had only demonstrated in front of Mokgetsu, shouldn't be cracked so easily, as it was created by combining the Sharingan's illusion abilities with Instant Body and Shadow Clone Jutsu.
Shisui immediately halted his charge, intending to retreat, not wanting to get closer to Kakashi now that the technique was broken.
However, Kakashi wouldn't let such a good opportunity slip; the three Shisuis weren't positioned far apart, allowing him to resolve them in one go.
