After taking over the snake uncle's foundation, Sasuke came to surrender on his own initiative.

"Hey, kid, I'm the famous boss of the Anbu. If you want to challenge the Hokage, I can't stop you. Who told me that I have so many things to deal with?" Kakashi glanced at Sasuke and continued, "By the way, your brother, Uchiha Itachi, also worked for me before, right?"

Hearing this, Sasuke's eyes widened instantly, and he was quite shocked. Because the identity Kakashi mentioned was much more powerful than he had imagined, and it could be said that it was a group of people standing at the pinnacle of power in Konoha Village.

"Oh, your brother Itachi is a tough guy. I can't guarantee that I can beat him. I might even get beaten up by him." Kakashi said while shaking his head and sighing, as if he was quite afraid of Itachi's strength.

After hearing this, Sasuke's heart sank. He originally thought that as long as he learned from Kakashi, he could defeat Itachi and avenge his family. Now it seems that things are far from that simple.

"But if you really want to learn something, I can teach you." Kakashi suddenly changed the subject, "But you have to pass my test first."

"Test? What test?" Sasuke asked curiously.

"Humph, you really don't know your place." Kakashi sneered, "Do you think revenge can solve the problem? Do you know that hatred will only make you fall into endless pain, make you lose your mind, and eventually lead to destruction?"

"I don't care, I just know that I must avenge my family!" Sasuke said firmly.

"Well, since you are so stubborn, I will give you a chance." Kakashi sighed, "If you can pass my test, I will personally teach you how to improve your strength. Otherwise, you can only find other teachers."

"Okay, I accept your test!" Sasuke agreed without hesitation.

So, Kakashi began to train Sasuke in various ways, including physical skills, ninjutsu, illusion, etc. After a period of hard work, Sasuke finally passed Kakashi's test and became his student.

In the following days, Sasuke learned many practical skills and strategies from Kakashi, and gradually grew into an excellent ninja. However, as time went on, he found that his obsession with hatred did not decrease, but became stronger and stronger.

Finally one day, Sasuke decided to face Itachi again to avenge his family. He found Itachi and the two started a fierce battle. Although Sasuke tried his best, he could not defeat Itachi. In the end, he was defeated by Itachi and was seriously injured.

Lying on the hospital bed, Sasuke recalled this experience and could not help but feel deeply moved. He realized that hatred could not solve the problem, but would make people lose themselves and fall into endless pain.

So, Sasuke decided to let go of his hatred and re-examine his life. He decided to use the knowledge and skills he learned to help those in need and become a true ninja.

"Look at this kid, he looks like a young sapling, can't he be obedient?" The old Hokage looked at Uchiha Sasuke who was lying on the bed with his eyes closed, then looked at Kakashi who was standing at the head of the bed, and couldn't help laughing.

"Hey, old man, please don't talk nonsense. Do I look ruthless? I'm just an ordinary ninja. It's not as exaggerated as you say." Kakashi spread his hands helplessly and joked, "Besides, do you think the Sharingan is suitable for Sasuke?"

"Oh my god, I didn't say the Sharingan is bad. But do you think it's appropriate to force Sasuke to learn how to clean up a situation with that kind of bloody and violent stuff?"

Kakashi's question made the old man speechless. The old Hokage stroked his beard and wondered: What should I do about this? The old Hokage thought for a long time and finally decided to listen to Kakashi: "Okay, just do as you say, don't go astray. Although Sasuke has lost some of the superpowers of the Sharingan, his temper has been calmed down, which also avoids the possibility of revenge against Konoha causing damage."

"Money makes the world go round. There's no need to make a fuss. As long as he's still within our sight, he won't cause any big trouble." The old man said to Kakashi affirmatively, with a gleam of wisdom in his eyes.

So, Kakashi began to teach Sasuke new skills. Peaceful days passed day by day, and Sasuke's strength improved little by little. Although sometimes young people made mistakes and the master would take out the cane to serve, but overall, Konoha was still okay, harmonious and stable.

Now, Uchiha Sasuke is faced with a major choice: Should he let go of his hatred, break free from the shackles of the Sharingan, and find his own value in life?

However, such a decision is not easy. Carrying the deep hatred of his family, Sasuke is struggling. Should he choose to bear the hatred blindly and never be satisfied, or choose to let go of the past and welcome a new life? Sasuke is still hesitating.

Seeing this, the old Hokage walked to Sasuke's bed again and advised him earnestly: "Child, let go of your hatred, it will make you crazy. Remember, you are no longer a child who only obeys others' orders, but an adult with an independent personality."

After hearing this, Sasuke was silent for a long time, and finally raised his head and looked at the old Hokage with a firm gaze: "Thank you, Master. I will try my best."

From then on, Sasuke started a new life. He learned how to control his emotions, how to get along with others, and how to face difficulties and challenges. He no longer relied on the power of the Sharingan, but gradually grew into a true ninja with his own efforts and perseverance.

The old Hokage looked at Sasuke's changes with satisfaction, and said with deep emotion: "It seems that my original decision was not wrong. Only by letting Sasuke walk out of the shadow of hatred can he truly find his own path in life."

Sasuke's master Kakashi smiled and said, "Old man, this kid has made rapid progress. He is much stronger than I was back then."

After hearing what Kakashi said, the old Hokage couldn't help laughing: "Hahaha, you are so spineless, you are not like Sasuke at all. But you are right, Sasuke has indeed grown a lot. It seems that the efforts of us old guys have not been in vain, and the future of Konoha is just around the corner."

During this time, Sasuke not only learned to control his emotions and get along with others, but also gained a deeper understanding of the side effects of the Sharingan and developed a deep disgust for it. He even began to feel ashamed of his past self.

"It turns out that I was so ignorant and stupid." Sasuke thought to himself.

As time passed, Sasuke's heart gradually became calm and strong, and his life began to change dramatically. He was no longer obsessed with hatred as in the past, but began to find his own value in life and his own belonging.

However, the desire for revenge still kept coming to Sasuke's mind, and he could not forget the pain and hatred he had experienced. Whenever he closed his eyes, those past scenes would reappear in his mind, making him unable to extricate himself.
