Testing the Mangekyō's Dojutsu

Uchiha Yao knew that before obtaining the Eternal Mangekyō, excessive use of the Mangekyō carried the risk of blindness.

Now, he had Dojutsu Adaptability: Extreme!

It directly reduced the side effects by 50%, while increasing Mangekyō mastery speed by 300%, saving him a tremendous amount of time in developing the Mangekyō.

He would also be able to quickly master the dojutsu granted by the Mangekyō, as well as God's Power, Susanoo.

Susanoo in particular could not be developed into its complete form in a short time.

With this supportive ability to accelerate his progress, Uchiha Yao was confident that he could quickly master the Mangekyō's dojutsu and the use of Susanoo.

Uchiha Yao walked over to a standing mirror, which clearly reflected his current appearance.

His face was still sharply defined, with hard, resolute lines.

But those eyes—

Had changed completely!

Gone were the three black tomoe slowly revolving around his pitch-black pupils.

In their place was a pair of Mangekyō Sharingan filled with majesty and oppressive power!

Left eye, Time Reversal!

Right eye, Technique Amplification!

This was the Mangekyō Sharingan that belonged to Uchiha Yao alone!

Time Reversal...

This was no simple rewind.

Uchiha Yao could feel that what this eye contained was the most rudimentary, yet most direct, interference with the laws of time.

He touched his right eye again.

Technique Amplification...

This was even more straightforwardly powerful.

Any ninjutsu in his hands would gain an unimaginable increase in power.

With the same Fire Release, someone else might only be able to burn down a tree, while he might be able to incinerate an entire grove.

"Phew..."

Uchiha Yao took a deep breath, forcefully suppressing the agitation in his heart brought on by his explosive increase in strength.

Now was not the time to indulge in power.

His top priority was to familiarize himself with and master this new power as quickly as possible, turning it completely into his own combat strength!

"First, let's try the left eye's ability... Time Reversal."

With a thought, Uchiha Yao focused his attention on his left eye.

The three sharp, sickle-blade patterns began to rotate faster under Uchiha Yao's mental control.

Uchiha Yao took out a kunai and cut open his arm.

"Reversal!"

He shouted softly.

The sickle-blade pattern in his left eye abruptly paused, then erupted with powerful ocular power!

Bzzz—!

An invisible ripple instantly spread outward from Uchiha Yao's body!

The next moment, something unbelievable happened!

The cut on his arm healed directly!

It was as though it had never existed.

The Chakra and stamina he had expended from awakening also returned directly to their full state!

In just a few breaths.

Uchiha Yao's physical condition had returned to an unprecedented peak!

"Th-This is the power of Time Reversal?"

Uchiha Yao's eyes were filled with shock.

This was far more than a simple healing technique!

It reverted his condition to a point in the past when he had been completely unharmed!

Though this reversal was not without limits, Uchiha Yao could sense that, under his current circumstances, this heaven-defying ability could only be used once a day.

Even so, it was already an utterly heaven-defying life-saving technique!

In battle, as long as Uchiha Yao still had a breath left in him, he could use Time Reversal to instantly return to peak condition and rejoin the fight!

Just imagine how despairing an enemy would be when they were already exhausted, only to discover that Uchiha Yao had suddenly returned to full strength.

And as Uchiha Yao's ocular power grew stronger and his understanding of the ability deepened, he would one day be able to reverse time across a wider range, over a longer period, perhaps even... for others!

Space reigned supreme, but time was king! A Mangekyō dojutsu containing the power of time possessed astonishing potential for development.

What a terrifying scene that would be?

"Next is the right eye... Technique Amplification."

Uchiha Yao entered the small courtyard.

He turned his attention to his right eye.

A wave of ocular power spread out from Uchiha Yao's right eye.

"Fire Release: Great Fireball Technique!"

With a low shout, he fiercely expelled the Chakra he had gathered!

Whoosh—!

A fireball the size of a human head whistled toward a wooden post!

This was Uchiha Yao's most basic Fire Release Ninjutsu, nothing particularly remarkable in power.

The three spiral patterns in Uchiha Yao's right eye suddenly began to spin faster!

Technique Amplification... activated!

Bzzz—!

Something unbelievable happened!

The originally ordinary fireball did not expand at all as it flew. Instead, it began compressing inward violently in a bizarre manner!

The flames rapidly changed from ordinary orange-red to blazing platinum-white!

Its temperature surged wildly!

The energy contained within it grew exponentially!

Boom—!!!

A terrifying explosion several times louder than any of his previous Great Fireballs rang out!

A violent shockwave, mixed with scorching waves of heat, swept in all directions!

The entire small courtyard shook violently beneath the impact!

Uchiha Yao instinctively raised an arm before his face, resisting the heat wave rushing at him.

When the smoke and dust dispersed.

The wooden post had vanished, and even the ground had been blasted into a crater several meters wide.

Th-This was still the Great Fireball Technique?!

Its power was already comparable to some advanced B-rank, or even beginner A-rank Fire Release Ninjutsu!

Uchiha Yao's eyes immediately lit up with wild delight!

Technique Amplification!

As its name suggested, it amplified the power of ninjutsu!

Moreover, this amplification was not a simple increase in the amount of Chakra. It fundamentally transformed the technique's qualitative nature!

Compression! Purification! Amplification!

It granted ninjutsu even more terrifying destructive power!

"What if... I used Technique Amplification on Lightning Release?"

Lightning Release was what Uchiha Yao excelled at most!

Especially his self-created Lightning Fire Dragon Breath, as well as the improved Lightning Release Chakra Mode!

If those techniques were enhanced by Technique Amplification as well...

Uchiha Yao simply did not dare imagine how terrifying their power would become!

Uchiha Yao forcefully suppressed the urge to try it immediately.

His own courtyard was still too small to test ninjutsu with excessive destructive power.

Lightning Fire Dragon Breath was out of the question, but he could try Lightning Release Chakra Mode.

Uchiha Yao immediately activated Lightning Release Chakra Mode!

Then he used Technique Amplification!

His speed and strength, already enhanced through Lightning Release Chakra Mode, suddenly increased once again.

Uchiha Yao estimated that this amplification raised them by at least thirty percent!

Crackle—!

The lightning enveloping Uchiha Yao's body no longer spread outward violently. Instead, it contracted inward, clinging tightly to the surface of his skin.

The Lightning Light changed from a dazzling bright blue to a profound dark purple.

The rate at which his Chakra was being consumed reached an alarming level!

He had to end this quickly!

The thought had only just arisen.

Yet Uchiha Yao's body reacted before his mind did.

He had merely intended to move from one end of the courtyard to the other.

Whoosh!

There was no sound.

No process.

One moment, he was still standing where he had been. The next, he had already appeared before a wall more than ten meters away.

His speed had been so great that his body remained in a forward-lunging posture, one hand instinctively pressed against the wall.

Crack...

The sturdy wall was like tofu beneath Uchiha Yao's hand, and he easily pressed a deep, cracked indentation into it.

Uchiha Yao slowly turned around.

He looked toward where he had been standing moments ago.

The ground there had cracked inch by inch from Uchiha Yao's instantaneous burst of power, forming a small depression.

This...

Was this Lightning Release Chakra Mode under Technique Amplification?

This was not speed at all. This was teleportation!

If it happened in battle, his enemy would not even be able to catch his movements!

After the wild delight came a sudden, searing pain.

Uchiha Yao immediately deactivated Technique Amplification and Lightning Release Chakra Mode.

In less than ten seconds of activation, nearly one-third of Uchiha Yao's Chakra had been drained.

More importantly, there was the burden on his eyes.

The Great Fireball Technique had only consumed a small amount of ocular power, but with Lightning Release Chakra Mode, not only was the Chakra consumption immense, roughly half of his ocular power had also been consumed.

This was a true trump card, one that could only be used in critical moments.

However, if this technique was paired with Technique Amplification, its endurance would be directly maxed out.

After testing the Mangekyō's abilities, Uchiha Yao looked at the two marks of destruction in the courtyard.

One was the crater caused by the Great Fireball.

The other was the cracked ground left behind by his teleportation.

"Looks like I'll have to get someone to repair this tomorrow!" Uchiha Yao said with a bitter smile.
