Naruto: If Sasuke Awakens Entry System

Kakashi's eyes narrowed, "Be careful, he is the S-rank rogue ninja—Momochi Zabuza!"

Sasuke felt a chill run down his spine, a murderous intent emanating from Zabuza. Such a strong aura meant this person was extremely dangerous!

"System, display Zabuza's entries."

[Water Style Proficiency (Purple ★★☆), Taijutsu Master (Purple ★★☆), Swordsmanship Master (Purple ★★☆), Silent Killing Technique (Purple ★), Murderous Oppression (Purple ★), Ambitious (Purple ★)]

"Is that all? It's far from Kakashi's golden entries!" Sasuke was immediately eager to engage.

Zabuza seemed to sense Sasuke's thoughts and sneered, "Little brat, I'll start with you!"

In an instant, Zabuza appeared behind Sasuke, his executioner's blade descending vertically. Sasuke's eyes widened—so fast! His body felt heavy, unable to move. Was this the oppression of killing intent?

Damn, I can't die like this! I still have to avenge Itachi!

"Sharingan, activate!"

With a whoosh, the Two Tomoe Sharingan appeared in his eyes. Sasuke's momentum surged, breaking through the suppression of killing intent. He turned and used a kunai to block the executioner's blade.

Bang!

Sasuke felt a tremendous force, his body sliding five or six meters across the ground. What immense power!

Zabuza's eyes flickered with surprise, "Uchiha clan?"

Kakashi breathed a sigh of relief.

Sakura called out anxiously, "Sasuke, get to Kakashi-sensei!"

Sasuke kept his gaze on Zabuza.

Zabuza waved his sword, pointing it directly at Sasuke, "Today, I'll face the legendary Sharingan!" With that, he charged at Sasuke.

In an instant, the two clashed fiercely.

Naruto was stunned, "Sasuke is actually holding his own against an S-rank rogue ninja?"

Sakura cheered, "Go, Sasuke!"

Kakashi was astounded. It was incredible that Sasuke could withstand Zabuza's killing intent. He didn't seem like a rookie fresh out of the ninja academy...

Zabuza grew more apprehensive as they fought. What an incredible learning ability—he's copying my taijutsu during the battle?

No, this can't go on. Kakashi is still nearby. I need to end this quickly!

Suddenly, Zabuza feinted and leapt to the water's surface, forming hand seals rapidly.

Chou, Shen, Mao, Hai, You...

Kakashi sensed danger, "Not good. That's a B-rank jutsu, Water Style: Water Dragon Bullet. With the water environment, its power could rise to A-rank!"

Sakura was anxious, "Kakashi-sensei, save Sasuke!"

Naruto was full of determination, "It's my turn!" He rushed towards Zabuza.

At that moment, Haku's voice rang out, "Don't interfere with Master Zabuza!"

Haku aimed at Naruto, "Secret Technique: Thousand Flying Water Needles of Death!"

Instantly, countless ice crystal-like needles shot at Naruto.

Sakura screamed in fear, "Naruto, watch out!"

Kakashi acted without hesitation, using the Body Flicker Technique to pull Naruto to safety. Fortunately, both were unharmed, but Kakashi's chakra points were sealed by the secret technique, preventing him from using ninjutsu temporarily.

In desperation, Kakashi stayed put with Naruto.

Meanwhile, Zabuza completed his seals, "Water Style: Water Dragon Bullet!"

A water dragon over ten meters long lunged at Sasuke with fangs bared.

Sasuke wasn't backing down, "Fire Style: Great Fireball!"

With a bang, the water dragon's head exploded but quickly reformed.

This is the advantage of the terrain! The endless sea water makes the water dragon nearly invincible unless a more powerful jutsu is used to destroy it completely.

Zabuza sneered, "The Sharingan is just so-so. Enough playing around, die!"

The water dragon lunged at Sasuke.

Death seemed imminent.

Sasuke slowly closed his eyes. Thump, thump, his heart pounded fiercely. Sakura and the others' screams echoed in his ears.

Suddenly, Sasuke's eyes snapped open, "I can't die like this! I... I still need to avenge that man!"

His entire body burned with determination, the unyielding fighting spirit in his chest transforming into boundless power, surging into his eyes.

Clang—

At the critical moment, Sasuke broke through his limits, evolving his Sharingan!

[Ding, congratulations to the host for breaking through the limit in battle, Two Tomoe Sharingan (Purple ★★☆) → Three Tomoe Sharingan (Purple ★★★)]

[Three Tomoe Sharingan (Purple ★★★), combines insight, copying, and illusion abilities, one of the most powerful bloodline limits in the ninja world.]

Almost simultaneously, all his chakra was restored and surged anew.

[Chakra: 5000 microcal (Jonin level)]

Sasuke's lips curled into a smile, the Three Tomoe Sharingan glowing with a strange red light.

Kakashi was shocked. He actually awakened the Three Tomoe in battle. What an extraordinary talent!

Naruto and Sakura didn't know about Sasuke's transformation, but they could feel his overwhelming presence, as if he had become a different person.

A nervous expression appeared beneath Haku's mask.

Zabuza snorted, "Three Tomoe, so what? You can't do anything in this situation. Die!"

Sasuke smirked coldly, leaping into the air. Swoosh, swoosh, swoosh, his hands formed seals so quickly they left afterimages.

"Fire Style: Great Dragon Fire!"

A fire dragon over ten meters long descended from the sky. It exuded an aura of dominance, as if looking down on the world.

The water dragon surged upward.

Boom!

The fire dragon and water dragon vanished simultaneously. The powerful explosion's shockwave affected an area within a 100-meter radius.

Naruto was incredulous, "How is it possible? Sasuke is already this powerful?"

Sakura was speechless.

Kakashi looked at Sasuke, thinking only one thing: genius, a true genius!

Boom!

Sasuke stood on the water, facing Zabuza, "Come and fight, the battle has just begun!"

Zabuza's face darkened, "Brat, don't underestimate me!"

He ran, intending to exploit Sasuke's weaknesses by drawing him out.

Strangely, Sasuke mirrored Zabuza's movements, matching his trajectory perfectly.

Kakashi's eyes narrowed, "Amazing, he's using the Sharingan to such an extent. The outcome of this battle is decided!"

Naruto was puzzled, "Kakashi-sensei, that guy without eyebrows seems strong. Sasuke might not win."

Sakura was annoyed, "Naruto, don't badmouth Sasuke!"

Kakashi smiled mysteriously, "Just watch, you'll see..."

Haku noticed Kakashi's words, growing more nervous under the mask, his heart filled with unease. Could Master Zabuza lose? No, impossible!

At this moment, Zabuza's face darkened further. He taunted while forming seals, "Brat, there's a limit to imitation. I'll show you that imitation is just imitation!"

Sasuke looked confident, perfectly copying Zabuza's hand seals.

It happened in an instant.

As Zabuza was about to complete his seals, something strange occurred. He saw a familiar figure behind Sasuke—himself!

Just as Zabuza was taken aback, Sasuke completed his seals first, "Water Style: Great Waterfall!"

A massive torrent surged forward like a giant beast.

Zabuza was shocked, overwhelmed by the waterfall, and fainted from severe injuries.

Kakashi shook his head with a wry smile. Sasuke single-handedly defeated an S-rank rogue ninja. What a monster!

Everyone gasped in disbelief.

Haku exclaimed, "Master Zabuza..."

As the words fell, Haku stood on the water, glaring at Sasuke, "Don't harm Master Zabuza!"
