'Aura production is done by Aura core. The production of Aura can be permanently increased by spells and training.' while thinking so, Kaiser starts walking forward.

'The production of Aura can temporarily be increased by will too but it happens rarely even in the most talented or gifted ones. Presently there is no practical record for it still it has been proven right.'

Kaiser finally stops walking -'This place should be right it is away from my house. There is not even any animal around here.'

The ground starts to shatter to pieces as Kaiser lets his Aura out.

As Kaiser lets his Aura of darkness out again, the wind near him starts to blow like a storm shaking even the deep and strong-rooted trees near him.

He calmly closes his eyes and takes a calm and deep breath.

As he does so he can see a golden shine in the darkness glowing more and less as his heartbeats.

He takes another deep breath as he does so the golden shine starts to glow more and less with each heartbeat of his own.

He slowly opens his eyes. His Aura is still unstable and releasing enormous amounts of energy causing wind near him to flow faster.

He releases a long breath from his mouth and just at not even a moment later his Aura bursts more covering his body thickly. The wind near him blows now no less than but instead surely more than a storm.

He smiles while thinking-'Well the most simple way I have to make my inefficient Aura efficient is to use the amount of Aura I don't want in my efficient one.'

"HAHAHAHA, Really how genius I am."

***

The worn-out Kaiser eating dinner with his family.

He thinks while eating slowly-'I think using too much of Aura made me tired.'

"Sigh "Kaiser couldn't help but let out a sigh.

"What happened, Son?"

"Nothing Dad just I am tired."

"Huh? Tired?"

Mom asks-"Honey did you make Kaiser train harder?"

"Uh, no not at all Honey Kaiser trained himself I did not even train him."

"How irresponsible." Mom said.

"Huh? Irresponsible?"

Mom says-"Kaiser do not train too much okay?"

"Okay, Mom." Kaiser answers with a wide smile on his face.

He finishes his dinner and gets in his room.

He closes the door of his bedroom and slowly sits on the floor with-"Sigh"

'Well, I used enough Aura today that I am totally worn out now. The bad thing is that I was tired enough that I was not even able to test whether my method to convert my inefficient Aura into efficient was even correct or not.'

He clenches his fist tight-'Well doesn't matter because no matter what I will do it Tomorrow!'
