16 Gyroscopic Rasengan

Haku closed the diary as he walked towards the room with jutsu books.

Haku stroked his chin as he looked at the books In Front of him.'The clan leader had a friend from the Uzumaki clan and the relations with them should have been pretty decent until Uzu was destroyed. I wonder if this place holds any more secrets. I don't know any fuinjutsu so it might be possible.' 

Haku then proceeded to check every self and cover of books for any kind of secrets.

He didn't find anything so he neatly arranged all the books in one corner and looked at the selves with weirdly shaped compartments for books.

The selves were hollow from both sides with borders on each row to separate the books, making the selves appear weird.

"Looking at the shelves after they are emptied, they do look weird. None of the compartments inside each row are nearly spaced. They all have weird gaps. There are even some slanted compartments!

Also, all the three selves are different in size and are hollow on both sides, making the books accessible from both sides of the shelf."

Haku was interested. For some reason, after emptying the shelves, they started to look even weirder.

Haku moved to different angles to observe the shelves properly. Suddenly! While he was moving in a circular pattern around the selves, something flashed before his eyes but it quickly disappeared!

'What was that!?' Haku immediately became alert.

Haku again moved back his steps. And he managed to stop at a certain angle and distance where the shelf's compartments all merged to create an illusion!

'I can understand the shapes merging to show another certain shape! But an illusion! Fuinjutsu is Wonderful.' Haku was elated because that meant the Yuki clan had some High-level fuinjutsu techniques probably stolen from the Uzumaki clan.

The shapes cast an illusion which wrote 'Break this for fuinjutsu and other. Prove yourself. Hint: Read all books 

'They shouldn't have put too complex seals on this. The problem is that I haven't even touched fuinjutsu so I probably need to explore outside and make a good fuinjutsu base to get the hint. Also the hint… thank myself that I didn't destroy these books.'

Haku then read the books all over again for the next three days while trying to find the Hint. But unfortunately, He couldn't find it.

'I should leave these books somewhere here. I don't think I will catch on the hint with some fuinjutsu knowledge.'

Haku put the books back on the shelves and closed off the basement by applying his blood on the pedestal again.

With that haku walked outside the compound after packing his stuff but he suddenly remembered something else.

"Rasengan! I think I can learn Rasengan now!"

Haku remembered the training process of Rasengan.

First was, rotation!

Haku tried to gather chakra in his Palms and rotate them in various different directions. Obviously, he failed for the first few times.

After trying for about an hour, he felt that he finally succeeded.

'I don't have a water balloon to test it… oh well, whatever. I will know whether it's successful or not at last anyway.'

Haku then proceeded towards the second step of Rasengan training!

Power!

He again made chakra rotate in different directions in his hand but this time he applied more chakra and kept increasing it until his hands started hurting.

After a while, Haku thought it had stabilized but he couldn't know for sure.

'Ah, I remember we do have a few rubber balls in the compound. It probably used to be a child's toy.'

Haku found 6 rubber balls in the compound.

He started practicing again!

The first rubber ball ruptured in a few directions but didn't get destroyed. Haku knew he needed to completely destroy the ball to pass this step.

The same happened to the next three balls they each had increasingly more damage on them.

Finally on the fifth ball!

BOOM

The rubber ball got destroyed! With this Haku had completed the second step of Rasengan training and only the third and the last step remains!

This step was called Containment. It might be hard or easy depending on your chakra control skills, for haku this step was obviously easy.

Haku let his chakra recover a bit and then stood up extending his palm then he combined the rotating chakra with a lot of power and tried to maintain the round shape of it.

He could slowly but surely do it but Haku knew that it was quickly destabilizing. So, Haku made it so that the whole shape itself starts rotating in one direction while the insides are still spinning in various directions.

Due to the gyroscope effect, the chakra that haku had rotated In the ball shape outside kept maintaining the shape. Haku had completed the Rasengan!

Haku then ran towards a treen and slammed the Rasengan in its trunk.

The tree's trunk was immediately pulverized with its insides making a pattern of rotating in one direction!

Creak-crack

The tree fell down, killing the plants in the ground.

Looking in the trunk of the tree Haku could see a rotating pattern in it.

'Weird, I am pretty sure normal Rasengan doesn't cause such patterns inside the object it hits. Did I accidentally create a new type of Rasengan by using the gyroscopic effect to stabilize it?'

"Good good, even if the ninja I hit with this somehow doesn't die, their internal organs will be mashed up with this! I will name this Rasengan variant - The gyroscopic Rasengan!"

Haku had accidentally created a new Rasengan type in just a few hours and even learned one of the most feared A-rank jutsu in that time.

'Well then, now that this is done. I should probably find a few subordinates, especially loyal ones. I have a few in mind from the cannon. The plan before getting the clan leader's jutsu was different but now I need to evolve this bloodline and experiment a lot, which requires a lot of money.

And an organization that does that for me seems perfect! But I need to form a method of loyalty for this organization first seals are out of the equation as I don't know how to make them so it should be an Ideology.'

Haku smirked as he remembered the ideology of pain and the greatest ideology of the ninja world—The Will Of Fire!
