Learning New Technique!

Holy Orchid Institute's training ground.

This was the best place for Ye Xinghan to train anything without being found.

There were a lot of torned water ballons and rubber balls around him.

Right now, he's gonna replicate the most famous technique known by all Weebs.

Rasengan!

Back when he was in One Piece, Ye Xinghan couldn't learn this technique because there was no such thing similar to 'Chakra' in One Piece.

There was only Haki, the manifestation of willpower. Quite different from the energy needed for making a rasengan.

But in the Tales of Demons and Gods, controlling soul energy was the very basic every practitioners know.

That's why, Ye Xinghan tried to imitate Naruto when he learned this technique!

The main composition of Rasengan is divided by three:

1. Rotation. The user need to spin their chakra in multiple directions at the same time. Users may be given a water balloon while they practice, to help them mark their progress by the churning water. The step is completed when users are able to burst the water balloon with their energy.

2. Power. The user increases the volume and density of chakra they output. To help in this regard, users may be given a rubber ball: there is no water inside to help them burst the exterior and the rubber shell is thicker than a balloon's. It's important that users are able to actually destroy the rubber ball, not merely rupture it, as only by destroying the ball will users know that their energy is sufficiently concentrated.

3. Containment. The user must combine the first two steps into a contained sphere. To help in this regard, users may be given a wind balloon to help them visualise the intended shape.

Ye Xinghan already succeed the first two steps in just 2 days. Thanks to researching a lot of ancient empire cultivation technique, Ye Xinghan's ability to control energy pathways already reached a high proficiency.

But, as his body is just 7 years old, the burden of learning rasengan was really huge. He used half of his earning from the restaurant to buy Recovery Pills.

Learning the first step wasn't really hard, as he had to do was directing the water to all directions. But, the second step was really hard, he used majority of his Recovery Pills during this step.

He need a recovery pill for each try with rubber ball. And he wasted a total of 35 pills before finally succed.

And today, he finally reached the final step of rasengan. The containment!

The problem was, the difficulty of this step was far higher than the previous two!

The balloon was either popped or moves, meaning his mastery and energy control wasn't sufficient to bring out the maximum power of rasengan.

*POP*

"GO*DAMN!" Ye Xinghan frustratingly shouted while throwing a torned wind balloon to ground.

"I only have around 10 recovery pills again, sigh." Ye Xinghan took a deep breath and relaxed his mind.

These nonstop learning really tire him out spiritually and physically, so Ye Xinghan decided to closed his eyes for a while.

'This tiny body doesn't have enough energy to maintain the use of rasengan, although I already practicing cultivation technique, it was far cry from Naruto who has Uzumaki bloodline as well as the demon fox.' Ye Xinghan thought while still closing his eyes.

'Maybe, I was too hasty with my progress? Probably I should wait for several years to try again? Wait for my soul energy reserves (Dantian) to reach a bigger size.' 

'Wait..' Suddenly, Ye Xinghan opened his eyes as he realized something.

"HAHAHAHAHAHA...." He suddenly laughed out loud as he thought about Naruto's shame.

Boruto!

Ye Xinghan grabbed a windball and concentrated again.

'If my energy isn't enough, how about reducing the size of rasengan?' 

Ye Xinghan gathered all of his soul energy to form a pingpong sized ball, he controlled the energy direction as well as compressed it to maximum.

Sure enough!

The wind balloon didn't explode! Ye Xinghan also felt the terrifying power coming from this balloon!!

"Gasp... Gasp.." Ye Xinghan heavily breathed, he didn't expect this tiny little rasengan to actually drained all his soul energy. He quickly took out a recovery pill and swallow it.

"Whoof, no wonder I couldn't form a normal sized rasengan. Even this tiny thing already exhaust me completely!" Ye Xinghan said while smiling, "Well, it's time to see this little guy's power."

Then, Ye Xinghan walked to a big tree that was around 50cm in diameter.

'Alright, this tree is strong enough. It woods is really hard. Lets Try!'

Ye Xinghan brought the wind balloon near the tree.

*CRACK!!* *CRACK!!* *BOOM*

But, the result made Ye Xinghan dumbfounded.

The moment the balloon touched the tree, it was actually destroyed in the middle, and split into two!!

It doesn't supposed to be like this!

"Holy cow, my mini rasengan contained so much power!" Ye Xinghan surprisedly said.

From what he remembered, Boruto's mini rasengan was only able to make a little dent to the tree. But, the mini rasengan in his hand actually have the power of Jiraiya's ordinary rasengan!

"Hehehe, probably because the difference of energy. Because the TDG world has cultivation technique, its energy was far more pure than chakra could ever be!

After all, the cultivation technique technically absorbing the natural energy and refined it to our own. It's the same as 'Sage Mode', except the sage mode contained many impurities, thats probably why anyone who try sage mode will turn into stone if they train recklessly.

Anyway, regardless of the reason, this is a really nice discovery! This mini rasengan alone could severely injure anyone below Silver Ranked!" Ye Xinghan smiled widely, now he has more trump card under his sleeves.

Coupled with his speed, it's like a mini version of Yellow Flash!

"Oof, looks like the sound of the falling tree is really loud. I should get out from here." After finishing his sentence, Ye Xinghan vanished.

Evening

Snow Wind Family's training ground

There were 3 figures fighting inside the building.

They were Head Servant Feng, Gyutarou, and Ume.

Ye Xinghan instructed Gyutarou to start sparring with Head Servant Feng to quickly adjust himself with gravity bracelet.

Ume already attended the school since a week ago. But, when she arrived at home, she immediately joined her brother.

Ye Xinghan told Gyutarou and Ume, to gave all they had with the intention to kill Head Servant Feng.

Of course, Head Servant Feng only shook his head helplessly when he heard about this.

The servants of Ye Xiao's mansion only snickered when they learned about Head Servant Feng's new duty.

Who expect the dignified gold ranked demon spiritualist were degraded into a nanny?
