In Naruto's endurance test, orochimaru had planned to take action against Konoha, so orochimaru took part in the endurance test after pretending to be at home. The second exam of Renzhong's exam was the scroll collection battle, in which Naruto met orochimaru. orochimaru was very eager after seeing sharingan of Sasuke, so he left Sasuke with a curse, hoping that Sasuke could come to see him. In order to gain great strength, Sasuke really went to orochimaru after the endurance test in China. Sasuke went to orochimaru to make himself stronger and have the power to defeat the weasel.

The reason why Sasuke's persistence became stronger.

Sasuke became stronger because of the genocide of Neiguang clan. When Sasuke was five or six years old, Neiguang Zongqin secretly planned a plan to rebel against Konoha. At that time, the skunk was already at the top of the dark part of Konoha. The skunk followed the genocide plan of Neiqibo, while the opposite Konoha wanted to protect the safety of his brother Sasuke.

However, few people know about this plan. Sasuke was only a few years old at that time, let alone know the plan. So Sasuke had an irresistible hatred for ferrets after witnessing his brother's ferrets kill all of them. At that time, Sasuke's only goal in life was to avenge ferrets.

Comparison of strength between Sasuke and ferret at that time

Uchiha Itachi is also a genius of Neiguang family. Together with Uchiha Shisui, he is called the Gemini of Neiguang family. Sasuke has a good talent, but he is certainly not as good as ferrets. Killing the weasel in Neiguang period should have had the power of movie level, and Sasuke at that time was only a forbearance.

After enduring the examination, the skunk and Mako once came to talk about Konoha and wanted to have a fight with Naruto, but their plan failed because of Jiraiya. When Sasuke heard the news, he did not hesitate to seek revenge on ferrets. He learned that Sasuke Thousand Birds should have the strength of forbearance, but he still has no ability to resist like a child in front of ferrets.

Sasuke should have known at that time that it was basically impossible to surpass ferrets with conventional training methods. Even if it can, it will take many years, but Sasuke doesn't want to wait any longer. In orochimaru, Sasuke can become stronger quickly, so Sasuke will not hesitate to go to orochimaru to make himself stronger in the shortest time.

Introduction of orochimaru's strength

Orochimaru is one of Konoha's three forbearance. After orochimaru defected from Konoha, he could study the forbidden art unscrupulously. Therefore, orochimaru has mastered many forbidden arts, but it is precisely because of his study of forbidden arts that orochimaru's soul is somewhat incomplete, and he will be easily knocked down by sharingan of ferrets when facing them.

And because of this, orochimaru is more interested in sharingan. At that time, there were only skunks and Sasuke in the world. Since the skunk can't beat Sasuke, it's natural to take Sasuke as a breakthrough, so orochimaru will leave Sasuke a spell of heaven, hoping Sasuke can find him.

But the setting of orochimaru in the early stage was really fierce. At that time, orochimaru tried to subvert Konoha and fight against Huo Ying's three generations while forbearing the exam. Not many people know the fighting process between them, but as a result, everyone knows. Three generations of Huo Ying died in this incident, and orochimaru also paid the price with his hands.

But Sasuke doesn't know. At that time, Sasuke thought that orochimaru could subvert Konoha by himself, so he killed Huo Ying. Finally, he left safely. This strength is absolutely incomparable, so it should be more advantageous to follow the strong, so he will choose to take refuge in orochimaru.

Sasuke followed orochimaru's strength for two years.

It should be correct for Sasuke to choose to follow orochimaru, because Sasuke has really made great progress in the past two years. In these two years, Naruto traveled and trained with Jiraiya, but his strength was not as great as that of Sasuke. Two years ago, Sasuke and Naruto had a fight on the rooftop of the hospital. Sasuke was obviously at a disadvantage at that time. Although it was organized by Kakashi in the end, if it is really the last move, Sasuke will definitely be run.

However, when Sasuke and Naruto meet again two years later, Sasuke's strength is overwhelming, and Sasuke should be able to easily defeat Naruto if he wants to. Enough to see the power of Sasuke before, there is a big gap between orochimaru and Jiraiya. Orochimaru must have used some means to improve Sasuke's strength, so Sasuke's strength will be improved so quickly, and growing up in battle is the best way to improve his strength.

And Sasuke has rich practical experience. It can be seen that Sasuke has definitely fought a lot in the past two years. However, when Jiraiya was teaching Naruto, he was more about life education and guiding Naruto's strength. Because there is Kyubi no Youko in Naruto's body, as long as Naruto can make rational use of Kyubi no Youko, he will not be weaker than anyone else. Naruto should play less these two years.

Ferret's attitude

Uchiha Itachi is very concerned about his younger brother Sasuke, and after Konoha's rebellion, the skunk returned to Konoha again, presumably to see Sasuke's situation. With ferrets' strength, maybe Sasuke will choose to take refuge in orochimaru, which he has already calculated. In the final battle between Sasuke and Ferret, Ferret also helped Sasuke clear the curse.

In fact, the skunk has arranged for Sasuke, and strength is the most important thing for ninjas. The ferret's own health is not very good, and the ferret must have thought about Sasuke's posterior approach. And let Sasuke practice with orochimaru, which can save Sasuke several years, and make Sasuke become a strong man faster, so that Sasuke can be independent after the ferret dies.
