The jutsu...

After hearing the request of Sora, the Third Hokage was stunned. After a while, he said slowly," Then you wait for me here, I will be right back."

Sora nodded. After a few minutes, the third Hokage returned with a thick scroll.

"This is the scroll of seals. It records the advanced ninjutsu developed and collected by the previous Hokages. Many of these techniques are very dangerous so, they are rarely seen by people. Only the ninjas with exceptional achievement can take a look."

Listening to the introduction of the scroll, Sora knew he hit the jackpot.

"You go through the introduction of ninjutsu then choose one. But remember that these Jutsu are extremely difficult to use let alone master properly. Once you choose, there is no place for regret so choose wisely." warned the Hokage.

Sora also knew that what the third Hokage said was true. He has personally experienced it with the shadow clone jutsu. Sora was able to learn this jutsu because of his memory of the show.

As mentioned in the show, shadow clone jutsu is an advanced form of basic clone jutsu. Sora had mastered the basic clone jutsu. According to the show, he tried to make the shadow clone jutsu by splitting his chakra evenly among the clones for them to become corporeal.

This was extremely time-consuming and Sora had to frequent the library often to solve the problems. Eventually, with the help of his knowledge about the jutsu and a full year of trials of error and mistake, he was able to learn the shadow clone jutsu.

( A/N: Some small details about how Sora learned this jutsu were shown in the previous chapter like the book of chakra splitting and training)

So, he was aware of the effort and work required to master an S rank jutsu.

Anyway, Sora opened the scroll of seals and glanced at the introduction of the jutsus. During his time browsing, he saw several familiar jutsu such as multi shadow clone jutsu, impure world reincarnation, eight gates, and many other ninjutsu.

But as the Third Hokage had said, many of these jutsu were very dangerous having an adverse reaction to the user. Some of the jutsu was even specifically for those with the corresponding bloodline limit.

'Perhaps because of so many forbidden techniques it is made into a scroll instead of separating them' thought Sora randomly.

Sora looked at more unknown jutsus until he found the jutsu he was looking for.

The Flying Thunder God Technique.

The Flying Thunder God Technique was developed by the second Hokage, Tobirama Senju. This jutsu is a space-time ninjutsu that can instantaneously teleport the user to the mark with the technique formula.

This jutsu is extremely powerful being the signature jutsu of the fourth Hokage, Minato Namikaze. But this technique's requirement is too high. It is impossible to learn directly. Even Minato himself was only able to master it combining his extremely high spatial talent and the sealing technique of the Uzumaki clan.

Sora had decided on this technique because he can only unleash the true power of his mystic eyes of death perception with this ninjutsu.

This technique gave Sora the ability of always striking first and with the one hit k.o ability of his eye, he may as well be borderline invincible.

" Sora, are you sure you want to take this technique, you know that only 5 people have ever learned this technique. Even the three full fledged jonins require to cooperate with each other to barely execute this jutsu."

Sora nodded with his eyes flashing with a firm light. Looking at the firm eyes of the boy, Hiruzen sighed and said,"Ok."

The third hokage no longer hesitated to lift the seal of the the Flying Thunder God Technique.

"You can memorise it here now."

Sora nodded and paid full focus on remembering each and every detail of the flying raijin jutsu. Perhaps due to his increased mental strength, his memory was also very good so he was able to memorise the jutsu very quickly.

After remembering the jutsu, Sora had his brows frown a little and said," Lord Hokage, I have memorised the technique."

Third hokage also nodded and resealed the technique. He then looked at the white haired boy and said encouragingly," This is your reward for your mission. I hope you continue to perform well, I have high hopes for you."

Sora nodded and taking this as a cue to leave, he quickly saluted and left.

A/N: I was a bit tangled between choosing the eight gates and flying raijin but thought that the build of Sora was perfect with the flying raijin. If you have any suggestions to improve the story, please let me know in the comments.

Please leave a powerstone for the cute new author ^ O ^ ~.
