Withered spirit -compleated

Chapter 14 Who's side are you one

After raiding the hospital for a few hours looking for tamable spirits issei was left with 5 that he could use as he wanted he spent the next week training with them alongside Megumi and Yuji now it was time for more physical tactics for him to learn

Issei: black flash?

He looked at them confused as to what they meant but showed his interest in what they wanted him to do

Yuji: yes, is a phenomenon in jujutsu that greatly amplifies the user's physical strike when cursed energy is applied to it within one millionth of a second.

Issei: how hard is it to achieve?

Yuji: only 7 people including myself has used it but only I and another person have used it multiple times in a row to achieve it

Issei: okay how do we do it

He put down what he had in his hands and walked closer to them

Yuji: just as you are about to land a hit on your enemy you increase your output to the highest that you can do and as you hit the target it builds an immense force that causes a black flash

Issei: alright let's get down to it

Megumi: it's not that simple I've tried believe me I've tried it's not happening that easily

Issei: okay then let's go we never maybe we even help you get it

Both Yuji and Megumi looked at each other and shrugged and started fighting they started getting Issei used to cursed weapons and had him use what he normally uses such as katanas and some fighting gauntlets

They had him attack Beast and his hits were getting harder and harder as he fought Beast they watched as scales grew around his face and arms and as he was about to hit Beast they watched him land a hit on Beast and he did it black flash it pushed the dust back beast was about to counter again and he hit it again and caused another black flash that sent beast flying into the wall

Issei stood tired and catching his breath.

Yuji: you actually did it

Megumi: I think it's because he's got fighting experience on top of learning new techniques and using them when he feels it's necessary

Yuji: don't be worried wort we just making sure the kid is keeping to the basics and hes improving on his own

Issei: what's next?

Megumi: domain expansion...

Issei: what's that?

Yuji: it's an advanced barrier technique and is considered the pinnacle of jujutsu sorcery. It constructs the user's innate domain inside a barrier infused with their innate cursed technique. Within a domain expansion, the user's cursed techniques are improved and any that are activated are guaranteed to hit.

Issei: I'm going to struggle with it aren't I?

Megumi: depends I opened mine when I was 15 it all depends on the user with you being able to copy almost every innate technique I do suggest that we first work on getting you used to barriers and how they work before you work on the domain

Issei: All alright lead the way...

They taught him further how barriers work and during this time he messed around and got used to the abilities as a whole he even mastered Boggie Woggie and used it better than its creator but during this time issei grew quieter realizing that staying neutral between everything is better than having emotion running wild like he normally would this also tamed his dragon better and allowed the powers to grow perfectly after a year it was time for him to leave
