(Another three chapters Back to back as thanks for the reviews. Post more reviews and power stones.)
———————————————
Like this time passed. Naruto also went out for shopping many times. He also went to the hot water baths using transformation jutsus to practice hot water walking. As he could easily walk on cold water, he needed to walk on hot water to further refine his chakra control. It took some time, but he finally mastered hot water walking. After mastering it, he went to the deserted Senju compound as it had a waterfall behind the compound. The compound was deserted because Tsunade was the last remaining Senju alive. After the second war, someone killed of every Senju except Tsunade. Might be Danzo as he didn't want another Senju with capabilities of being Hokage.
Finally after walking for sometime, he came across the waterfall and he started trying to climb the waterfall. His shadow clones were also doing their jobs at the Namikaze compound as well. After a week, he mastered waterfall climbing. After getting adequate chakra control, he started Rasengan training using water balls first and then rubber balls. It took him a month to use Rasengan one handed. He then started adding lightning element to create vanishing Rasengan and be able to throw it like Boruto without sage mode.
It took him three months to perfect the vanishing Rasengan. He added lightning element in the rasengan and it only took him 10 days to achieve that with the help of shadow clones. The remaining time was used to learn to be able to throw the Rasengan and perfect the aim of throwing it and make it vanish at the exact timing. It's harder than you think. But in three months, Naruto was able to perfect it. Now he's learning Oodama Rasengan. The big ball Rasengan will come in handy in a lots of cases. Thanks to the fox's chakra, it's possible to create it many times as well.
A total of 1 years passed since Naruto first stepped into the Namikaze compound. The blood clone also did it's job splendidly just sitting in places like parks and showing a feeling of loneliness to the onlookers and the Anbu as well. Hiruzen also meets the clone from time to time and offers to get him food to which the clone politely refuses every time giving reasons like he has cooked at home and it will go waste and he didn't want to waste food as he only gets a very little amount for it. Sometimes he also says that he's not so well and can't eat.
This day Naruto was almost 6 years old. Hiruzen approached the blood clone and asked "Naruto, do you want to join the academy?" The clone thought for a moment and replied "Ok. I'll join." Hiruzen nodded and gave a speech of Will of fire to the clone and went away saying that he will submit the application for Naruto to join the academy. Like that the life of academy started for the clone. The clone was not like the canon Naruto. He just minded his own business in the class and didn't do much. His scores were consistent throughout and he lost some sparing matches on purpose as well.
Naruto was already genin level when he created the clone. He just pumped some chakra whenever he grew taller to make the clone taller as well. This was the modification he made to the blood clone after studying the original jutsu. In the academy, Naruto was not dumb. He performance was just like any other civilian students that attends the academy. He didn't stay at the academy after the classes ended as he ran straight home. He was not late, but arrived right on time. He didn't make any friends or spoke to anyone. So he wasn't close to shikamaru, or thought Sasuke as a rival. He didn't even bat an eye to Sakura. He felt her disgusting fawning over Emo Sasuke.
Even everyone in the class also didn't care about Naruto as he didn't do any pranks and didn't stand out in the class. This way, Iruka also didn't take notice of him and the student teacher relationship never developed. Also as he didn't rescue Hinata from the bullies, she also didn't care about him. The clone was just sitting in the corner minding its own business. The main body at this time was practicing using senbon needles as it would be easier to carry a lot of them and will work well with the more more fruit speed increase in the later stages.
He also started practicing stealth mode by hiding his presence. He had mastered calligraphy and basic fuinjutsu and was learning intermediate fuinjutsu. He also found some stealth seals made by Kushina which when applied will hide the users chakra and presence. He was trying to blend with Nature as much as he can to perfect stealth. He was a master of stealth and infiltration in his previous life as he infiltrated very high security nuclear weapon stations with ease. He just needed a way to hide his chakra and control his body moments and breathing as it was a rather new body and a body of a child at that.
The reason he was practicing stealth is simple. He wants to steal many things like forbidden jutsu and the like under the noses of the Anbu and the old man. He also wants to infiltrate the Root headquarters and steal some things they have there. Also make Danzo's life miserable. Like this with arduous training, another year passed and it was time for the faithful day of the Uchiha massacre. A day with the Red moon.
