Naruto: I was reborn as Uchiha Sasuke

On December 64th, 12th year of Konoha, it had been more than half a year since Uchiha Sasuke arrived at Orochimaru's base.

During the past six months, Orochimaru not only generously provided Sasuke with the Kusanagi sword, but also took the trouble to personally train him in the practical combat of the Ninja Sword Illusion. The training requirements were so strict that it was shocking, and each time was like a cruel torture. Every time when he was exhausted from training, Sasuke would kneel on one knee, support his knees with both hands, and breathe heavily, as if he wanted to inhale all the air in the world into his lungs. However, he kept encouraging himself in his heart: "In order to survive the subsequent brutal battle, this little bit of suffering is nothing!" After that, he gritted his teeth, veins on his forehead bulged, and he stood up again tenaciously and threw himself into training without hesitation.

Witnessing his growing strength, Sasuke clenched his fists, his joints turned white due to the force, and the determined light in his eyes became brighter and brighter, like the stars that never go out in the night sky. He thought to himself: "This progress is far from enough, I must be faster and stronger, so that no one can stop me from moving forward!" He was very clear that his current growth rate was far faster than when he was in Konoha, which was a rapid progress.

During this period, Sasuke devoted himself to the study of ninjutsu. He often sat alone in a secluded place, closed his eyes and meditated, like a quiet statue. He kept rehearsing various ninjutsu techniques in his mind, as if he was building a ninjutsu treasure house of his own. He had already mastered the Chidori Senbon and Chidori Style, and the Chidori Ninja Tool Series that he once relied on gradually retreated to the second line. As for the Chidori Sharp Spear, Sasuke frowned, like two tightly furrowed mountain peaks, thinking to himself: "I must not let Orochimaru see through all my cards." Thinking about it, he shook his head slightly, clenched his fists, and his nails almost embedded in his palms. After making up his mind, he began to explore alone.

In the experimental field, Kimimaro's cells were fused with the Hyuga clan's cells in vitro for treatment, which achieved certain results and extended his life to a certain extent. The remaining experimental direction is the in vitro fusion treatment of Kimimaro's cells with the Uzumaki clan and Senju Hashirama.

Sasuke's eyes were determined, as if burning with raging fire, and he personally begged Orochimaru to conduct a fusion experiment between his cells and Naruto's cells. He clasped his hands together, bowed slightly, and said sincerely: "No matter what, as long as it can make me stronger, I am willing to try any method." After completing the transplant on his own body, he carefully conducted chakra tests. He quickly formed seals with his hands, and his ten fingers flexibly fluttered like a smart butterfly dance. Chakra surged in his body like surging waves. Unfortunately, the result was only a slight improvement, not very significant. But Sasuke was not discouraged by this. Instead, he straightened his spine, like a proud pine tree, and became more and more determined to continue exploring in his heart: "This little setback is nothing, and I don't have much hope."

As for the curse seal, Sasuke also tried hard to master it. After many attempts, he concluded that the first state of the curse seal can be used for 15 minutes, and the second state of the curse seal can be used for 5 minutes. If the time limit is exceeded, Sasuke finds that negative emotions will slowly take over like a tide, which is not good for him. Therefore, Sasuke decided:

1. In the later stage, he insisted on using the curse seal mode twice a day. Every time he turned on the curse seal, he would take a deep breath, tense his whole body, and think to himself: "I want to overcome the negative effects of this power and make it fully work for me." Let the body gradually adapt for 15 minutes to maximize the combat power. 2. During the battle, always look for opportunities and frequently switch to remove the curse seal mode. Move quickly and decisively, on the one hand to maintain the continuous combat level, on the other hand to maintain the number of lethality.

In the afternoon, Orochimaru sat in the room with a gloomy face. The atmosphere in the room was as depressing as the calm before a storm. Then he called Sasuke in loudly: "Sasuke-kun, the Land of Fire has issued a jonin escort mission to the Otogakure. After repeated consideration, I have decided to send you and Kimimaro together." As he spoke, Orochimaru crossed his hands and tapped his fingers rhythmically. The crisp tapping sound echoed in the silent room. There was a hint of uncertainty in his eyes, as if he was hiding an endless conspiracy.

Orochimaru thought to himself: Since Tsunade became the fifth Hokage, the relationship between Konoha and the Land of Fire has indeed eased. First, the corruption case of the Konoha Administration Department was exposed. Tsunade supported the establishment of a supervisory department without hesitation. Not only did she detail and standardize the ninja mission bonuses, but she also pardoned the ninjas in the Administration Department and recovered the corrupt funds. However, even so, the government of the Land of Fire still adopted the model of combining Konoha with other ninja villages in issuing missions, and the actual proportion of Konoha is gradually decreasing. Sasuke has connections with the dignitaries of the Land of Fire, and that's why he got this mission. However, the money he can earn from it is also considerable, but he still has to keep a close eye on Sasuke's every move, and he can arrange for Kimimaro to supervise from the side.

After hearing Orochimaru's order, Sasuke bowed slightly and replied in a very respectful tone: "Yes, Teacher Orochimaru. I will go inform Kimimaro right away, and then we will set off together. Sorry to bother you." After that, he turned around and prepared to leave. His figure looked a little lonely in the light and shadow, but he was thinking in his heart: I wonder what kind of tricks this Orochimaru is up to.

Orochimaru was almost accustomed to Sasuke's politeness, and even a little numb. At this moment, he was still struggling fiercely in his heart, whether to seize Sasuke's body. At the same time, another voice sounded in his mind: he could try to clone the blood of multiple ninjas and merge them into one. But Sasuke's amazing growth rate, and the plan to transform the world he proposed during his leisure time communication with him, made him waver in his thoughts. But after thinking it over again and again, he finally listed Sasuke's body as the first target 1, and the cloned body as target 2. After all, he was Orochimaru who had an immortal body. Even if target 1 failed, there was still target 2 as a backup.

After Sasuke left the room, he took a deep breath and looked up at the sky, with a lot of thoughts in his mind. He knew that no matter what, he had to be fully prepared for this mission and face everything that was about to happen.
