The Truth About Uchiha Massacre.

---

"This…"

"???"

"Kirito, how did you do it?"

Might Guy couldn't suppress his emotions at this moment.

The scene Kirito had just shown was so shocking it could even be said to have shattered Might Guy's worldviews.

He, Might Guy, had actually encountered such a thing in his life.

He had learned ninjutsu since he was a child, including the Eight Gates of Dunjia from his father. And now, to think that someone who had only practiced the technique for less than half a year had modified it in such a profound way.

And the changes were so great that Might Guy couldn't even begin to understand how it was possible.

How did this happen?

In truth, Might Guy had practiced the Eight Gates of Dunjia for 20 to 30 years. During that time, he had even thought about modifying the technique himself. After all, the Eight Gates is extremely harmful to the body once activated. He had tried many times to adjust this drawback, but each time, he was met with failure, regret, and confusion.

Eventually, Might Guy had given up on the idea of modification altogether.

But now, hearing Kirito's words and seeing the results firsthand, he was excited beyond belief. This was a breakthrough he had never expected.

Sasuke, who was watching on the side, was at a loss. He had never trained in the Eight Gates Ninja Technique, nor did he fully understand its principles or powers. So, Kirito's words didn't have the same immediate impact on him. However, seeing Might Guy's excited and trembling expression, Sasuke realized that his teacher, Kirito, had done something extraordinary.

The cold gaze of Sasuke observed every movement between the two, but he stayed silent.

"Kirito, tell me, how did you do it?"

"Quickly…"

Might Guy's excitement kept urging Kirito for an answer. His expression was like a lioness in heat, having found a strong male lion.

Kirito raised his hand slightly, signaling Might Guy to calm down.

"Kai, don't get excited yet."

"Listen to me and I'll explain it step by step."

"Actually, after discovering the mystery, I started trying it repeatedly."

"Might Guy, all you need to do is…"

"..."

"The key point is reversing the chakra energy stored in your body."

"Finally, the modified Eight Gates Ninja Technique is complete."

"I'll call it the Reverse Eight Gates Ninja Technique."

As Kirito finished speaking, golden light sparked in Might Guy's eyes. It was as though he had just been enlightened, and he radiated a feeling of immense benefit from what he had just learned.

The next second, Might Guy followed the process Kirito had explained. He raised his voice and shouted:

"Eight Gates of Dunjia, open the Gate, open!"

Upon opening the first gate, Might Guy immediately began to feel the changes in his body. A grin spread across his face, and he shouted once more:

"Rest Gate, open!"

"Life Gate, open!"

"Injury Gate, open!"

After opening four gates in succession, Might Guy unleashed several punches into the air.

Bang! Bang! Bang!

A series of explosive sounds echoed in the air.

"Hahaha…"

Might Guy threw his head back and laughed, expressing his joy.

"Kirito, I don't even know what to say."

His words were filled with excitement, and his face was full of gratitude toward Kirito.

However, Kirito merely smiled faintly in response and handed the original copy of Might Guy's Eight Gates Ninja Training Notebook to Sasuke.

Sasuke didn't hesitate. He opened the notebook, which was filled with dense text detailing Might Guy's original practice of the Eight Gates Ninja Technique. As he flipped through the pages, Sasuke found a few sections marked with a different colored pen. These were the modifications Kirito had made to the original Eight Gates Ninja Technique, now labeled as the Reverse Eight Gates Ninja Technique.

The more Sasuke read, the more his eyes widened with shock. After a moment, he slowly closed the notebook and a mixture of emotions flooded his face.

"Teacher, you…"

Sasuke hesitated, unsure of what to say.

He finally understood why Might Guy had reacted so intensely earlier. The small modifications Kirito had made to the technique had resulted in a completely new physical skill. Although it wasn't as powerful as the original, Kirito had completely eliminated its drawbacks, transforming its weaknesses into strengths.

This was the teacher, Kirito, whom Sasuke had always admired.

"Good boy, your teacher, Kirito, is truly a god."

"He can teach your team, and you three should consider yourselves lucky."

Might Guy gave Kirito a thumbs-up and then addressed Sasuke.

"Don't worry, Teacher Kirito. I won't let you down."

"I'll grow strong enough and take down that person myself."

Sasuke's words were filled with intensity, and he gripped the notebook tightly in his hands. Anger and hatred radiated from him.

Kirito frowned slightly. He knew that the "person" Sasuke was referring to was his brother, Uchiha Itachi. Sasuke's biological brother had become the one Sasuke longed to kill.

Kirito knew he shouldn't interfere in the feud between the two brothers. After all, in the original plot, Sasuke would eventually kill Itachi. However, the truth of Itachi's actions was far more complicated than Sasuke realized.

Uchiha Itachi had killed his own clan not out of cruelty, but because he had been forced into a corner. The Uchiha clan had been planning a coup, and when Itachi discovered his father's involvement, he was caught between his loyalty to his family and his duty to Konoha. In the end, he sided with Konoha for the greater good of the village, committing the massacre to prevent a civil war. Itachi had spared his brother Sasuke, hoping that one day Sasuke would avenge the clan.

But Sasuke didn't know any of this. He was driven by anger, blinded by revenge.

As Sasuke's teacher, Kirito felt he should tell Sasuke the truth. If he didn't, Sasuke would inevitably make a decision he would regret in the future.

With that thought, Kirito placed a gentle hand on Sasuke's shoulder.

Sasuke, whose eyes were filled with rage, was stunned by Kirito's gesture. His confusion was evident in his eyes.

Before Sasuke could speak, Kirito's calm voice echoed in their minds.

"Sasuke, sometimes your eyes can deceive you."

Might Guy stayed silent, and Sasuke stared at Kirito, his face tense, unsure of what was coming.

"Your brother Itachi didn't really defect."

Sasuke looked at Kirito with confusion, a hint of numbness in his gaze.

Kirito continued, speaking softly but firmly.

"Back then, your Uchiha clan was given an important mission by Konoha. But over time, they became increasingly distant from the center of power."

"Your clan was dissatisfied with the higher-ups in Konoha, and your father, Uchiha Fugaku, planned a coup."

"But Itachi discovered his father's plot and was torn. As the captain of the Anbu, he was in a position of power, yet he had to choose between his loyalty to his clan and his duty to the village."

"Danzo, upon learning of the coup, threatened Itachi. He demanded that Itachi wipe out the Uchiha clan."

"After much internal conflict, Itachi chose to protect the village. He killed his own family, but spared you, Sasuke, because he loved you."

"And before he left, he made it clear to Danzo that if anything happened to you, he would expose the village's secrets."

"After that, he joined the Akatsuki under Obito's guidance, in hopes of keeping you safe from the shadows."

"….."

As Kirito's words sank in, Sasuke's eyes slowly filled with tears.

His once-calm gaze began to turn red.

With a roar, blood flowed from his eyes as his Sharingan activated.

"Ahhhhhh…"

"Why… why did he make that choice for me?"

Sasuke's Sharingan spun rapidly, transforming into the Mangekyō Sharingan.
