Susanoo

Regardless of the reactions within the Uchiha clan, Shisui Uchiha could not wait to leave the clan grounds and arrived at the forest on the north side of the village.

"Fire Style: Phoenix Sage Flower Nail Crimson."

"Fire Style: Great Dragon Fire Technique."

"Fire Style: Great Fireball Technique."

Shisui Uchiha discovered that with the enhancement of the Mangekyō Sharingan, the speed and power of the ninjutsu he unleashed were far greater than in his previous life.

He had a premonition that this enhancement was related to the fact that his left eye's dōjutsu in this life, "Yamata," had replaced "Kotoamatsukami."

Although it was not as exaggerated as the Mangekyō dōjutsu "Kagutsuchi," it was well worth the consumption of the Mangekyō Sharingan.

"It is not just the strengthening of ninjutsu; my vision, dynamic tracking ability, and physical fitness have also been significantly enhanced. It truly is the strongest eye of the Uchiha."

In his previous life, Shisui had also awakened the Mangekyō Sharingan, but at that time, in order not to fuel the momentum of the radicals within the clan, he had always restrained himself from using it.

By the time he intended to use the power of "Kotoamatsukami," his right eye was stolen by Shimura Danzō.

In this life, Shisui had the opportunity to carefully experience everything the Mangekyō Sharingan brought.

"Next, it is time to try that move—the ultimate dōjutsu of the Mangekyō."

"I wonder if the version unleashed in this life will be any different from the last."

That was right; what Shisui Uchiha was about to unleash was the supreme dōjutsu residing within the Mangekyō Sharingan: Susanoo.

"Susanoo."

For Shisui, who had once awakened Susanoo with a single eye, activating it with a complete pair of Mangekyō was as simple as breathing.

As the Mangekyō in Shisui's eyes accelerated their rotation, a massive amount of dark green chakra began to condense on his body surface, forming huge ribs and arms that shielded most of his body.

This was the initial form of Susanoo.

Following this, a large amount of dark green chakra continued to condense into more skeletal parts, and the size of the Susanoo grew continuously, forming a green, half-bodied skeletal giant.

"This is not enough." At this moment, Shisui could feel that this state was far from reaching his limit, so he immediately increased the infusion of chakra.

Under the support of the massive amount of chakra, the giant skeletal Susanoo continued to rise in height, meridians and patterns grew on the bones, and the chakra was condensed into flesh and blood, finally wrapped in a layer of cloak-like chakra. A spiral sword also condensed in the giant's right hand.

Shisui's Susanoo bypassed the first form and reached the level of the second form.

In his previous life, Shisui had activated this form through his left Mangekyō and repelled Danzō and his Root subordinates.

In this state, Shisui's Susanoo already possessed its exclusive skill, which was "Susanoo: Yasaka Magatama."

When the skill was activated, the chest armor of the Susanoo would open, firing countless green chakra arrows from the center for long-range attacks.

Up to this point, Shisui felt that his condition was still good.

"Both eyes are not overloaded, and there is still plenty of chakra. Let's see where my current limit lies."

"Third form, activate!"

At this moment, Shisui no longer held back; all the chakra in his body was mobilized and began to surge toward the Susanoo behind him.

The iconic Crow Tengu Helmet began to cover the Susanoo, its overall defensive power increased significantly, and the height of the entire Susanoo reached several dozen meters.

Reaching this step, he was already approaching Shisui's limit.

Although Shisui's eyes were not bleeding, the soreness coming from them was already reminding him that his eyes could only go this far.

As for the subsequent fourth form, forcing it open would only cause irreversible damage to Shisui's eyes.

A non-Eternal Mangekyō Sharingan also lacked sufficient ocular power and chakra to stabilize a fourth-form Susanoo.

"Hoo."

Shisui took a deep breath and began to control the fourth-form Susanoo.

The massive spiral sword began to rotate rapidly; the wind it generated alone blew the surrounding forest into disarray, sending dust flying.

"Pierce."

The Susanoo thrust the spiral sword in its hand fiercely toward a small mountain, and the sharp blade instantly pierced into the mountain body.

Accompanied by the continuous rotation of the blade, the sword acted like a giant drill, advancing into the mountain without pause, crazily destroying its interior.

A large amount of sand and stones splashed outward, all of which were blocked by the Susanoo on Shisui's body, until the entire small mountain was pierced through.

"The offensive capability is not bad, especially in terms of single-point penetration. It is perfect for breaking an enemy's turtle shell."

Next, Shisui controlled the Susanoo to try various other offensive methods until his eyes began to feel sore and swollen again.

"Susanoo: Release."

Having achieved his goal, Shisui directly dispersed the third-form Susanoo.

The massive Susanoo body also turned into scattered dark green chakra, returning to the heavens and earth.

"The ocular power in my eyes has suffered irreversible loss. After all, it is still not an Eternal Mangekyō."

"No, it is not entirely irreversible, but the speed at which ocular power recovers is simply too slow—so slow that it can be ignored."

For the Uchiha, who value martial strength, it is difficult to suppress the urge to use dōjutsu after obtaining the Mangekyō Sharingan. The fact that the eyes cannot get sufficient rest and recovery is the fundamental reason for the loss of vision.

"Before my eyes go completely blind, I can still activate the third-form Susanoo three or four more times. It seems I will have to be frugal with the use of my Mangekyō abilities in the future."

Before achieving the Eternal Mangekyō Sharingan, every pair of Mangekyō Sharingan faces the same problem.

[Congratulations to the host for successfully awakening the Mangekyō Sharingan. Please head to Kirigakure as soon as possible to meet with Uchiha Madara. Reward: Fire Release proficiency +50%]

"A 50% increase in Fire Release proficiency? With this, my fire-natured chakra will see another boost. But why would he choose to meet me in Kirigakure?"

Regardless of what schemes Uchiha Madara might be plotting, Shisui was not worried that he would pose a threat to his life, given that Madara had lost his Rinnegan and was relying solely on transplanted Three-Tomoe Sharingan.

While Shisui was still planning when to set off for Kirigakure, he did not expect that an uninvited guest had already arrived at his home.

"Clan Leader, why are you here?"

Just as Shisui stepped through his front door, he found Clan Leader Fugaku Uchiha waiting in his courtyard.

"You're back, Shisui. Let's have a chat."

There was not the slightest hint of anything unusual in Fugaku Uchiha's tone, but Shisui knew that the man had most likely come because of the Mangekyō Sharingan.

"Your eyes—have they evolved again?"
