Naruto: Blade of the Sharingan

At the same time, a faint smile touched Uchiha Nagi's lips. The reason he sought a fight with Tsunade was, needless to say, to copy her techniques. If he hadn't encountered her, it would have been one thing, but since he had, not "stealing" a few of her skills would be an injustice to his golden finger. Now, the Monstrous Strength Fist was his.

"Your gaze is really irritating. Just like that lecherous Jiraiya, it makes me furious—" "Damn you! Heavenly Foot—!" Tsunade roared, enraged. His gaze made her extremely uncomfortable; it reminded her of when Jiraiya had successfully spied on her bathing. And in reality, it was quite similar: he had succeeded in "stealing her techniques"...

From the very beginning, his Mangekyo Sharingan had been constantly spinning, meticulously copying Tsunade's every skill.

"Ninja Art: Body Pathway Derangement—!"

Facing the aggressive Tsunade, Uchiha Nagi chose to evade this time, because this technique, Body Pathway Derangement, was a medical ninjutsu. Its principle was to inject Chakra transformed into electricity into the enemy's body, paralyzing their nervous system and rendering their limbs immobile. Against an expert of this caliber, a single mistake could cost him his life.

Uchiha Nagi's Mangekyo flashed. He used the Body Flicker Technique, simultaneously switching to Wind Breathing to augment his speed.

When Tsunade's attack was about to hit Uchiha Nagi, her body wavered for a moment. But this wasn't a mental ninjutsu like Tsukuyomi that combined time and illusion. So Tsunade, having experienced the Great Ninja Wars, immediately noticed it. Thus, in less than a second, she broke free from the genjutsu. By that time, Uchiha Nagi had already flickered away and was no longer in his original spot; Tsunade could only hit empty air once more.

"Bakayaro—!" Tsunade was incredibly fierce, attacking relentlessly.

Facing this "She-Dragon" – a mere graze from whose fist could mean pulverization – Uchiha Nagi dared not be careless in the slightest. On one hand, he kept his Susanoo primed within his Mangekyo, ready to release it instantly if he couldn't dodge. With the Mangekyo's dynamic vision, releasing it before she hit him was definitely not a problem. On the other hand, Uchiha Nagi continuously employed the Breathing Styles and sword techniques he had learned. Opportunities for an all-out battle were scarce, especially against an enemy who wasn't holding back. He had reaped great rewards from his previous battle with Akaza, and after that fight, during his special training with the Stone Hashira, his Chakra had nearly doubled again.

Uchiha Nagi sensed that Tsunade currently had slightly more Chakra than him, close to ten units, while he had seven. It seemed comparable, but she also had the seal on her forehead. Once released, she wouldn't just be an HP tank but a Chakra tank as well.

Uchiha Nagi crouched slightly, and a snowflake-like sigil appeared around his body. "Technique Deployment: Compass Needle—"

He began to swing his Nichirin Blade at high speed, unleashing the technique he had copied and modified, changing it from a fist-based release to a sword-based one.

"Destructive Death: Air Type—!"

Air Type was a technique Akaza had used against the Flame Hashira, a long-range attack that launched air cannons by punching. Their trajectory was invisible to the naked eye, and their power was immense. If one wasn't a battle-hardened veteran relying solely on eyesight, they would likely suffer. Tsunade, of course, was not in that category. Ninja battles sometimes ended in an instant, but before that, there would be many rounds of probing, such as testing the opponent's ninjutsu, abilities, and so on—

BOOM!!

Tsunade stomped heavily on the ground. The earth cried out again, splitting apart as soil and debris flew. She had kicked up a huge earthen wall, or rather, a mound of earth. Compared to Kakashi and others who needed various hand seals to release an Earth Style ninjutsu for defense, Tsunade's method was simpler, cruder, and more effective.

Hundreds of Destructive Death: Air Type strikes all hit the earthen wall. Countless clods of earth flew high into the air, the scene looking as if it had been shaved flat by countless blades.

Hooo~ Uchiha Nagi took a deep breath, switching his breathing. "Water Breathing, Seventh Form: Drop Ripple Thrust—!"

This was the fastest sword technique in Water Breathing. It might not be as fast as Thunderclap and Flash in terms of raw speed, but as the versatile jack-of-all-trades Water Breathing, its yielding nature didn't fear hardness, making it the safest option against Tsunade's extremely hard and forceful taijutsu.

"Bastard, don't underestimate me!" Tsunade threw a powerful punch.

At this moment, Uchiha Nagi's Mangekyo flickered. Since he had a practical and powerful Mangekyo genjutsu for combat, why not use it? This genjutsu was even stronger. Tsunade was instantly caught in the illusion.

Pfft—

"Lady Tsunade—!" Shizune cried out in grief.

Before Shizune's disbelieving eyes, Uchiha Nagi's longsword successfully pierced Tsunade's body.

Uchiha Nagi frowned, not feeling like he had won just because he had stabbed Tsunade. She possessed the Creation Rebirth, an undying ninjutsu. As long as she released the Yin Seal on her head...

However, the stabbed Tsunade's lips curled into a slight smile...

Crap—!

The Tsunade who had been stabbed transformed into mud—it was an Earth Clone. Simultaneously, the ground beneath him softened, turning into an Earth Release trap that firmly pinned Uchiha Nagi's feet.

A trap...

Uchiha Nagi could have quickly swung his sword to sever the earth restraining his legs and escape the trap, but now his blade was firmly stuck in Tsunade's Earth Clone, unable to be withdrawn.

"Bastard, die—!"

With a boom, Tsunade burst out from another patch of earth, a Monstrous Strength Fist packed with power hurtling towards Uchiha Nagi. If this punch landed, his body would likely have a gaping hole blown through it, or his bones would be shattered into paste.

"Susanoo—!"

At the critical moment, he still had to rely on his "Gundam." The skeletal Susanoo manifested, firmly blocking Tsunade's sure-kill technique.

With a thunderous crash, the Susanoo, already showing fine cracks, enveloped Uchiha Nagi and sent him flying back several dozen meters. Its two skeletal hands dug into the earth, carving a deep trench, before finally dissipating the force of Tsunade's Monstrous Strength Fist.

"So that's how it is. While you were using Earth Release to block my hundreds of Destructive Death air blades, you set up an Earth Clone and a trap, then your real body underground. Then the Earth Clone pretended to be caught in my genjutsu. Truly one of the battle-hardened Sannin. The slightest carelessness can get one killed," Uchiha Nagi lamented. This was ninja combat: deceptive, insidious, cunning—

He had been biased from the start, thinking of Tsunade primarily as a taijutsu and medical ninja, neglecting the fact that she could also use the five elemental releases. But in reality, Tsunade was a "PhD of Five Elemental Ninjutsu," a disciple of Hiruzen Sarutobi. It wasn't strange at all that she could use the five elemental releases. It was just that no ninjutsu was as satisfying as her punch, so she rarely used them. He had been careless...

"Lady Tsunade—!" Shizune quickly ran to Tsunade's side, then glared at Uchiha Nagi with a murderous look. The reason was, Tsunade was trembling, her face etched with fear. Just now, when Uchiha Nagi was sent flying by Tsunade's punch, the distance had been too close. Although he had defended with Susanoo in time, the powerful physical impact had caused a trickle of blood to escape the corner of his mouth...
