Quickly wear from Naruto Yakushi Kabuto

Sasuke and Kabuto came to Orochimaru's gloomy and mysterious secret laboratory.

The laboratory was filled with the pungent smell of chemicals, and various strange instruments and equipment were flashing strange lights. Orochimaru stood in the center, his eyes revealing enthusiasm and expectation.

"Sasuke, are you ready to accept new power?" Orochimaru smiled sinisterly.

Sasuke had no expression on his face, only a desire for power in his heart: "Let's start."

Orochimaru then drew Sasuke's blood and began the experiment impatiently.

At this time, Kabuto pushed his glasses and said slowly with a serious face: "Lord Orochimaru, the Uchiha clan's bloodline limit is mysterious and powerful. It is said that their Sharingan has many magical abilities such as insight, replication and hypnosis. Moreover, with the strong fluctuations of the user's emotions and the improvement of strength, the Sharingan can continue to evolve, from ordinary single magatama, double magatama, to three magatama, and even Mangekyō Sharingan. Every evolution brings a qualitative leap in power. The Mangekyō Sharingan possesses extremely powerful and unique eye techniques, but its side effects should not be underestimated. Excessive use may cause blindness. But if you can successfully control this power, you will be invincible." As he spoke, a shrewd look flashed in his eyes.

Orochimaru nodded slightly while operating the instrument: "Yes, Kabuto, you understand it very thoroughly. If this experiment is successful, Sasuke will become the sharpest weapon in my hand."

Sasuke said coldly: "I am not your weapon, I just use your power to get revenge."

Orochimaru laughed strangely: "Haha, Sasuke, no matter what, you are here with me now, so you have to listen to me."

Kabuto narrowed his eyes slightly and continued, "Lord Orochimaru, the Uchiha clan's bloodline limit has a special way of inheritance. It seems that only under the stimulation of extreme pain and hatred can a more powerful power be stimulated."

Orochimaru snorted, "Humph, this is exactly what I expected. The pain will make him stronger."

Sasuke clenched his fists and said through gritted teeth: "No matter how painful it is, I can bear it."

Kabuto looked at Sasuke, a barely perceptible smile on his face, and thought to himself, "This guy is desperate for revenge."

At this moment, the experimental instrument made a "sizzling" sound, and Orochimaru shouted excitedly: "Almost there, almost there, it will succeed!"

Sasuke's eyes became more determined, as if he had seen the hope of revenge.

After a series of events in that secret laboratory, Orochimaru became more and more appreciative of Kabuto's performance.

One day, Orochimaru gathered his men together. He stood in front of them and said with a cold look in his eyes: "Kabuto, this man has great potential. You all have to cooperate with him in the future."

The men looked at each other in bewilderment. One of them, a burly fellow with a face full of flesh, stood up and said disdainfully, "Lord Orochimaru, why should we listen to him? I want to challenge him. If he can defeat me, I will accept your defeat!"

Orochimaru frowned, but before he could say anything, Kabuto took a step forward and said calmly, "Okay, come on then."

Everyone came to an open space, and the atmosphere around them was tense and depressing.

The challenge began, and the subordinate roared and rushed towards Dou, swinging his thick fists, creating a gust of wind. However, Dou dodged the attack easily.

Seeing that his attack missed, his subordinate became even more angry and launched a series of fierce physical attacks.

Dou was not in a hurry, dodging flexibly while observing the opponent's flaws. Suddenly, he saw the right opportunity, turned sideways, stretched out his palm, and gently patted his opponent on the back.

This seemingly gentle slap contained powerful force, and the subordinate staggered forward a few steps.

He steadied himself and was about to turn around to attack again, but Dou instantly appeared behind him, raised his leg and kicked him to the ground.

The subordinate struggled to get up, but Kabuto didn't give him the chance. He quickly stepped forward and formed seals with his hands, "Ninja Technique: Palm Immortal Technique!" A green light enveloped his subordinate, making him groan in pain.

After just a few moves, the challenge ended with Dou's complete victory.

Kabuto looked at his opponent lying on the ground and said calmly: "Now, are you convinced?"

The subordinate's face was filled with shame, and he gritted his teeth and said, "I... give in."

Orochimaru smiled and said, "See, Kabuto's strength is worthy of your cooperation. You are not allowed to have any objections in the future."

Everyone nodded, and their attitude towards Dou changed from contempt to awe.

After a long and arduous research in the laboratory, Orochimaru finally succeeded in extracting the Uchiha bloodline.

Kabuto stood aside, his eyes revealing desire and greed. When Orochimaru temporarily left the laboratory to deal with other matters, Kabuto picked up the bottle of precious bloodline and thought to himself: "Maybe I can gain great power with this."

He injected the blood into his body without hesitation, but almost instantly, he felt a strong rejection reaction. His body seemed to be cut by countless sharp blades, and the pain made him fall to the ground and roll around.

"Ah..." Kabuto groaned in pain and his face turned as pale as paper.

But he still held a glimmer of hope in his heart, hoping that he could integrate this power. However, as time went on, the rejection became stronger and stronger, and he knew that he had failed.

“Damn it, my blood won’t merge…” Dou gasped, feeling unwilling.

At this moment, he remembered the system he had and prayed silently in his heart: "System, I can only put my hope in you. Please let me sign in and get the Sharingan."

He waited in agony, not knowing whether the system would respond to his expectations.

Damn it, the blood doesn’t merge…” Dou panted heavily, feeling unwilling.

At this moment, he remembered the system he had and prayed silently in his heart: "System, I can only put my hope in you. Please let me sign in and get the Sharingan."

He waited in agony, not knowing whether the system would respond to his expectations. Every second of waiting seemed like endless torture, and sweat continued to drip from his forehead.

Suddenly, the mechanical voice of the system sounded in Kabuto's mind: "Sign in successfully, obtain the Sharingan, and start integrating the Uchiha bloodline limit."

Dou instantly felt a powerful force surging in his body, and the original pain was gradually replaced by a strange feeling. He closed his eyes tightly, his body trembling slightly, trying to adapt to this force.

When he opened his eyes again, he had successfully opened the Three-magatama Sharingan. In those blood-red eyes, three magatama slowly rotated, emitting a mysterious and powerful aura.

Kabuto felt the new power, his heart filled with surprise and excitement: "Finally, I have this powerful power!"

He stood up, adjusting to the new perspective and perceptions the Sharingan brought him.

When Orochimaru saw Kabuto awaken his Sharingan, a rare happy smile appeared on his gloomy face. His narrow eyes stared at Kabuto, full of admiration and expectation.

"Kabuto, very good, it seems that you have a promising talent." Orochimaru said.

Kabuto bowed his head slightly and responded respectfully: "Thank you for your appreciation, Lord Orochimaru."

Orochimaru continued, "You will conduct more experiments with me in the future. I believe you can play a greater role."

Kabuto readily agreed, "Yes, Lord Orochimaru."

Over the next year or so, Sasuke and Kabuto worked hard to improve themselves. With his own talent and the resources provided by Orochimaru, Sasuke's strength improved significantly.

With the help of the sign-in system and hard training, Kabuto's strength has improved even more dramatically. He has not only mastered various ninjutsu, but also made a qualitative leap in combat skills and strategies.

Today, Kabuto has the strength of an elite jonin. During a training session, Kabuto easily defeated several powerful opponents, demonstrating his great strength.

Orochimaru watched from the side and nodded with satisfaction: "Kabuto, your progress has exceeded my expectations."

Kabuto smiled and said, "This is all due to Lord Orochimaru's cultivation."

However, deep in his heart, Kabuto had his own plans. He knew that his strength needed to be further improved before he could compete with Orochimaru.
