After releasing such a huge amount of aura Sen falls due to exhaustion
Karan catches Sen and takes him to his house
He puts Sen on a bed so that he can get some rest.
After a few hours, Sen wakes up
He goes outside the house and finds Sultan talking to Hari
Sen-"EHHHHHH??????"
Sultan-"what?"
Sen-"Why the hell are you here???"
Sultan-"why shouldn't I this is my home."
Sen-"Arent you like the strongest in this world."
Sultan-"Yea so what?"
Sen-"don't you have like fights you have to attend?"
Hari-"Now now Stop it you both.
Sen, Karan has an important meeting to attend right now so we called sultan to teach you about the coating."
Sen-"Coating?"
Sultan-'Just follows me."
sultan takes Sen to a training area
Sultan-"Coating is covering yourself with aura.
we all use a coating to make our attacks and spells stronger."
Sen-"Ok."
Sultan-"But if you use coating properly you can use it like this."
sultan coats his hand with his red aura
His aura then starts to widen and becomes a big fist.
Sen looks at the big fist and tries to do it himself
He coats his left arm with his aura and also makes a sparkling blue Big fist
The shocked sultan asks sen
Sultan-"How did you do it on your first try."
Sen-"Well I know Energy conservation so it's pretty easy."
Sultan-"Energy conservation?"
Sen-"They didn't teach u this?"
Sultan-"Nope"
Sen-"It's like coating but you use your energy instead."
Sultan-"Ok so you focus your energy at one point for it."
Sen-"Yes!"
Sultan-"Do you have a weapon?"
Sen-"Yea I have a sword."
Sultan-"Show it to me."
Sen pulls out his sword and shows it to the sultan
Sultan-"This won't work."
Sen-"What?"
Sultan-"It can't be coated with aura."
Sen-"Wait you can coat weapons?"
Sultan-"YES"
Sultan pulls out his hammer and coats it with his crimson red aura
He throws his hammer up
It goes up into the sky through all the clouds and comes back to him.
Sultan-"I made this weapon with aura and it always comes back to me when I want it to."
Sen-"WOW"
Sultan takes sen to a basement full of equipment
Sultan-"you can make your weapon here."
Sen-"Sure"
Sen takes A Tsuka (Handle of a KATANA)
He then takes some metal pieces nearby and starts heating them and turning them into liquid
He then takes a blade-shaped vessel and fills the liquid in it
after cooling he takes out the hard metal and starts hitting it with a hammer
after hours of trying and trying he gives up on making a sword of himself
A silver piece of metal starts glowing
He touches it and it suddenly takes the form of a blade and attaches to his handle
A huge purple light starts glowing from the basement
Sen goes to check the light and finds a handle on the floor
He picks it up
The handle starts to suck all the energy out of Sen
Sen tries to fight it but falls unconscious
While he is unconscious he enters the realm of swords
With his new sword in his hand, he goes searching for a way out
After a while he finds a man floating in the air
???-"You tried to tame me the king of swords but you couldn't."
Sen-"what?"
???-"I am ENMA and I am here to end your life once and for all."
