Mad Sasuke, Vector Manipulation

"Itachi, Uchiha Itachi... Do you realize how ridiculous you sound to yourself!!!"

As Weasel used Body Flicker Technique to appear behind Sasuke, his eyes had changed, showing a scarlet six-pointed star, and a wicked smile appeared on his face.

"So you underestimated me because Sharingan saw my weakness, and you thought I wouldn't react?" Itachi was surprised and then realized.

"Go die!!!"

Sasuke didn't give Itachi a chance to speak.

With a terrifying burst of power from his feet, Sasuke's body disappeared instantly. He possessed not only the Mangekyō Sharingan but also the abilities he gained from Academy City, controlling electricity, heat, and kinetic energy.

His speed was astonishingly fast, even faster than Itachi expected, and it caught Itachi off guard despite using the Body Flicker Technique.

Before Itachi could react, Sasuke was already in front of him, and the terrifying six-pointed star was reflected in his eyes.

A small kick came from behind Itachi.

"Although you've given me many surprises, your physical strength is still too weak, and you're too weak overall," Itachi said, his eyes showing a mix of emotions.

He reached out to try and catch Sasuke's kick.

Meanwhile, Sasuke's grin grew even more wicked. "Underestimating me comes at a price," he said.

Itachi smiled slightly. "Foolish brother, Mangekyō's eyes are not invincible. Today, I will teach you that in the face of absolute power..."

Before he could finish his sentence, he was interrupted.

"Oh, you've been fooled." The blood-red six-pointed star in Sasuke's eyes spun rapidly, and blood almost poured out of his eye sockets. He was still too young to handle such power.

His body also experienced severe pain.

The burden of using Sharingan was too great. Sasuke's current mind had limited computing power and needed Sharingan's ability to help with vector operations.

"Stupid brother, although I don't know what happened to you during this time, your weak strength won't be enough..." Itachi started to say, not taking Sasuke's power seriously.

But then, a terrifying power erupted.

A power that was beyond his imagination.

Itachi's scalp went numb. It was a power that could develop vector operations to an invincible level, able to crush the planet into an iron ball beneath his feet.

Even before Sasuke came to this world, he had developed Academy City to the point where the planet stopped for five seconds.

Even though Sasuke had just awakened in this world and only used a limited version of his age domain due to the incomplete development of his superbrain, it was enough to deal with Weasel.

In an instant, a round, transparent, and terrifying semicircle condensed at one point due to kinetic energy and wind energy.

The entire house shook, and countless gases erupted from all sides, visible to the naked eye.

Itachi was in a frenzy, vomiting blood.

His eyes were directly beaten by this blow, leaving him confused and questioning life.

"My dear brother, it turns out that unknowingly, I've already..."

Itachi muttered to himself.

The power erupted instantly, bursting with kinetic energy.

The power of vector operation didn't leave any doubt. At any point, it could burst out unparalleled terrifying power through the calculation and change of kinetic energy, electrical energy, and thermal energy.

Itachi's whole body was wrapped in skeletons, but he vomited blood and smashed directly onto the road. A large pit was created, several meters in diameter and one to two meters deep.

And at that moment, just ten meters away from Itachi, Uchiha Obito, wearing a mask, looked at Itachi, who was covered in blood and tortured.

He was aware of Mangekyō's strength.

He knew Itachi's strength even better.

A twelve- to thirteen-year-old Itachi combined with the power of Mangekyō was already a proper Kage-level.

Yet, the Susanoo-powered Weasel was abused by blood like this?

Obito slapped himself hard to snap out of his shock.

Then, he took a deep breath.

Not far in front of him, a beautiful and delicate-looking girl with three Tomoe Sharingan in her eyes watched the scene in fear.

Burst!

Itachi vomited another mouthful of blood.

His whole body was shaking.

Who could explain what was happening?

Was the world going crazy, or was he just dreaming a nightmare?

If it was a nightmare, Itachi wanted to wake up quickly.

This was terrible.

Why was his younger brother, who had been attending a ninja school for only two years, displaying such power?

He, Uchiha Itachi, was the strongest and top genius of the entire Uchiha clan!

It was incomprehensible!

He was thirteen years old, and he was already a Kage-level powerhouse.

On what grounds did Sasuke have such power?

Burst!

Just thinking about it, Itachi spat out another mouthful of blood.

A single kick almost resulted in his immediate death.
