In the ninja world, Sharingan genjutsu isn't considered the most powerful. It can be broken with a simple disturbance in chakra.
But the premise is that external help is needed; otherwise, it is impossible to break the Sharingan genjutsu. This is why the Uchiha clan has always been so strong in one-on-one combat—they are adept at using their Sharingan.
However, just now, Danzo had broken free from the genjutsu in half a second.
This made Shisui start to doubt whether Danzo had some special forbidden technique or perhaps even his own Sharingan, which could explain his resistance to the genjutsu.
Before Shisui could dwell on these suspicions, Danzo didn't let him linger on the thought. After failing to land a blow, he removed his eye patch and revealed a crimson Sharingan.
The three-tomoe Sharingan in Danzo's eye was rapidly changing before Shisui's eyes, slowly transforming into a normal eye.
Shisui's expression turned wary, and he immediately questioned Danzo, "Danzo, why do you have a Sharingan? When you broke free from the genjutsu just now, you must have used an Uchiha secret technique."
Danzo nodded and spoke openly, without any hesitation, "Indeed, I have a Sharingan, and I've learned some of the Uchiha clan's secret techniques. These techniques were all gifted to me by Kagami Uchiha. He was truly a kind-hearted Uchiha."
At the mention of Uchiha Kagami, Shisui's face darkened, and he said with displeasure, "Danzo, you have no right to speak of my grandfather. I will report everything that happened today to the Hokage, and let him punish you."
"You think you'll be able to leave here today?"
Danzo smiled, though he hadn't succeeded with his surprise attack, he had already laid an ambush in the area. More than a dozen elite ROOT ninjas were positioned around him, and with their combined attack, he could still take down Shisui.
"So, you really intend to make a move against me?" Danzo said with a laugh.
Shisui drew a short sword from his waist and pointed it directly at Danzo's head. In the next instant, he vanished in the blink of an eye, activating the Body Flicker Technique.
Dozens of afterimages appeared in the open space, surrounding Danzo. From multiple directions, they began their assault.
At the same time, Shisui activated his Sharingan, attempting to use genjutsu to interfere with Danzo's actions.
But Danzo showed no sign of trying to avoid the attack. After forming hand seals, he took a deep breath, filling his lungs with air, and then suddenly expelled it.
In an instant, a blast of wind from his Wind Release technique shot toward Shisui. The gust of wind sliced through everything in its path, severing even solid rock with ease.
With the enhanced dynamic vision of his Sharingan, Shisui easily dodged the wind blast and quickly closed the distance toward Danzo.
Danzo furrowed his brow. He pulled two or three shuriken from his pocket, infusing them with wind chakra. The shuriken instantly took the shape of blades made of wind, and they shot out in three different directions.
Under the sharp force of the wind blades, Shisui's afterimages were shredded, leaving only his real body, holding the short sword, still facing Danzo.
Feeling Shisui's unwavering gaze, Danzo's expression shifted, fluctuating between uncertainty and determination.
After transplanting Hashirama's cells, his strength had returned to its peak but even with that, he still couldn't defeat Shisui in such a short time.
This was the terrifying power of the Mangekyo Sharingan. In just a few years of training, Shisui had surpassed Danzo's decades of accumulated strength.
Danzo's desire to obtain the Mangekyo Sharingan grew even more intense. Only with that power would he be able to combine the strength of the Senju and Uchiha clans.
Determined not to hold back any longer, Danzo unlocked the seals binding his arm.
These seals had restricted the power of the Hashirama cells inside him, as well as kept him from being overwhelmed by them and turning into a tree-like being.
Once the seals were released, Danzo would gain access to an immense chakra reserve.
Feeling the power that had been unleashed, Danzo bit his finger and slammed it onto the ground. With a puff of smoke, the legendary summoning creature, the Dream Membrane, appeared on the ground.
In terms of size, the Dream Membrane was not particularly impressive. It wasn't on the same level as the tailed beasts of natural disaster class, nor was it comparable to the summoning beasts of the Three Great Sage Lands.
However, the Dream Membrane was one of the few summoning beasts that could use ninjutsu, and it was especially adept at Wind Release, making it a perfect match for Danzo.
Seeing Danzo summon his beast, Shisui wasn't about to back down. Drawing upon a large amount of chakra, a greenish-blue projection enveloped his body, transforming into a giant Susanoo, towering over ten meters tall.
Shisui controlled the Susanoo, launching an attack at Danzo and the Dream Membrane by swinging his spiral sword.
As the spiral sword struck the Dream Membrane, cracks resembling spiderwebs appeared in the ground beneath it. The creature let out a loud roar and unleashed a violent gust of wind from its mouth, attempting to destabilize the Susanoo.
Danzo's face darkened further as he observed this. He was now in a precarious position. He neither had the strength to defeat Shisui nor the desire to let him leave.
If he took any further action without thinking, and if Hiruzen Sarutobi found out about it, the consequences would be unimaginable.
The Uchiha clan would consider him an enemy to the death, and all his plans would be shattered, ending his hope of ever becoming Hokage.
Continuing to use Susanoo in his attack, after the spiral sword grazed its nose, the Dream Membrane let out a pained cry. It was already struggling to hold its ground in front of the Susanoo.
Danzo, watching the Dream Membrane's predicament, proceeded to remove the seals on his arm.
As long as he could remove all the seals, he would still have a chance to defeat Shisui. And he wasn't fighting alone—he had other subordinates.
Suddenly, Danzo seemed to realize something. His pupils dilated sharply.
They had been fighting for quite a while, but none of the ROOT ninjas he had previously hidden around the area had appeared yet.
Could it be that Shisui wasn't alone? Had he brought reinforcements?
Recalling their earlier meeting, especially the moment when his ambush on Shisui failed, Danzo quickly replayed the events in his mind. A few drops of cold sweat appeared on his forehead.
Perhaps Shisui had known all along that Danzo would make a move here and had made preparations in advance.
Wasn't Shisui just a tool of Hiruzen Sarutobi, a foolish Uchiha who harbored the Will of Fire? How could his plans be so meticulous?
Could it be that Shisui was truly the mastermind behind the Nine-Tails attack?
At this thought, Danzo's mind began to consider escape. After giving the Dream Membrane its orders, he tossed a smoke bomb onto the ground, trying to obscure his movements and leave the area.
Just as he attempted to flee, a group of fallen ninjas suddenly appeared in the direction Danzo had intended to escape.
These ninjas, wearing animal masks, were all Danzo's subordinates. Standing near them, however, was a young ninja.
The young ninja was none other than Byakuya, who had witnessed the entire battle.
Byakuya looked at his former superior, slowly speaking, "Danzo, where do you think you're going? After attacking your comrades in the village, are you now trying to escape and flee from your crimes?"
