## 3 year passed ##
It was 1 month before the graduation from academy. Sasuke has train hard in these 3 years. He reached high level chakra control. He can form a rasengan in a second. He also started to visit hospital for his training in medical ninjutsu after getting permission from the Hokage. He copied advanced version of shodow clone jutsu, 'multi shadow clone jutsu' two years ago from a jonin while watching him spar with another jonin in training ground. When he learned this technique he was able to form only two shadow clones but now he can make twelve shadow clones. Although the amount of chakra he has now is three times as it was two years ago but his chakra control has improve a lot.
His training with Guy brought him great benefits. Two and half years ago Guy taught him eight gate techniques and now he can open upto the third gate. He would be able to open the 4th gate in one year with his current speed of training. He now mostly spars with Rock Lee who can open upto 5 gates. With his sharingan he is able to keep up with 5 gate open Rock Lee with his three gates open. If he uses his genjutsu and ninjutsu then Rock Lee is no match for him.
Sasuke never go all out against Rock Lee and neither does Rock Lee goes all out against him, however when he spars with Guy he give it his all. He combines his clan taijutsu with 8 gate technique, although using sharingan with 3 gates open is very chakra exhausting and he cannot last more than 6 minutes but he is able to make Guy open his 4th gate.
His kenjutsu training is also going well but since he neither spars with anyone in kenjutsu nor trained by a sensei in kenjutsu so he don't know his level in kenjutsu. His genjutsu has become his greatest asset. He can easily put an elite jonin in genjutsu with his three tomoe sharingan and if he uses his mangekyou sharingan, then even a level kage shinobi will have hard time resisting it. His only weakness was his low level chakra.
Due to his high genjutsu standard he had copied many fuinjutsu and ninjutsu from places he was not supposed to go. Although he has not mastered all these techniques but he still have photographic memory of them. Untill now he has mastered total of 5 fuinjutsu, they are; barrier seal, perimeter seal, chakra absorbing seal, storage seal and exploding tag seal.
Barrier seal can cover certain area and no one from outside can probe inside. Perimeter seal can inform the person if anyone enters the seal covered area. Chakra absorbing seal can help absorb chakra from the enemy.
These seals cannot be use for combat purposes but they are very useful in other aspect. First seal is very useful anti-spying function. Second seal is used for getting intruder alert. Third seal useful for infiltration but it has a drawback. With chakra absorbing seal it became really difficult for sensors to differentiate between enemy chakra and the person whose chakra was absorbed by the enemy.
There are few drawback to this seal, first the person whose chakra is being absorbed should remain under the sealed space for some time and be perfectly still. So it cannot be use in battle, second it allows user only 10 minutes. After that user will be back with original chakra signature. Third, if he get too close to sensor they will something is not right.
It was not easy to learn these fuinjutsu without Uzumaki bloodline but Sasuke was a reincarnated person, he manages to do it due to his other personality. After learning barrier seal he used it to erect a barrier around underground place he previously found. He practices his mangekyou there. He still needs his mangekyou to summon susano but he is slowly getting the hang of it.
He have been doing a lot of sneaking and occasionally interrogated weak root ninja about their base. He finally have location of root base and tonight he is going to infiltrate the base to get cells of Hashirama Senju. He wanted to awaken the rinnegan and for that he needs both Indra and Ashura chakra. He eliminated Naruto for getting the Asura chakra as he don't know how Naruto contain Ashura chakra, he have no idea if there is some kind of seal that made ashura chakra in Naruto's body inaccessible. Hashirama has sage body and moukton and since sage of six path also have sage body and Ashura got this from his father and hence Hashirama has sage body. Only thing special about Naruto is kyubi so he don't understand how Naruto is Ashura reincarnation. Even the sage mode he learned was due to his own effort.
Sasuke caught a root ninja and quickly absorb little bit of his chakra. He have already interrogated few root ninja by putting them in genjutsu. Since he knew that they are unable to say any secret regarding Danzo, so he put them in genjutsu in such a way that they felt as if they are giving direction to new root member to the research facility.
