"The shop is right around this corner" Cynthia took me to the skill shop she mentioned earlier

We both entered the skill shop

"Welcome!" a middle-aged man greeted us, looks like he's the store owner

"Are you looking for skills?" He asked

"Yes" I replied blankly

"Please state your class"

"I'm a swordsman while she's a healer"

"Then please choose from this book" The shop owner took out two books from the shelf behind him and gave it to us

I looked through the skill book but all of them were not suited for me or my style, however, on the last part of the book I saw something I did not expect

{

Illusion Strike

Makes the user Invisible and makes the target of the skill fall into a confused state wherein they will see illusions of the user

}

This should be good, I looked at Cynthia to check if she has chosen a skill.

"I'm also done here" Cynthia read what I was thinking and spoke

"Are you done?" the shop owner asked

"yes" both Cynthia and I replied

We both handed back the books and pointed at the skills that we want

"[Lightning] for the lady and [Illusion strike] for the man" He returned the books and took out a scroll

"That would be 1000 silver coins, 500 silver coins each" The shop owner said

Oh crap, I forgot about my energy levels.

Cynthia and I went back to the guild but there was no one inside so we quickly to the forest behind the guild to practice the skills we bought.

"So, how do we do this?" I asked Cynthia

"Please channel your mana towards the scroll" Cynthia replied

"uhm... what is mana?"

"Mana is the energy that we can use in order to use magic, it is present in every living being"

"can I be considered living?" I muttered under my breath

"Hm?"

"Nothing, please continue"

"Human's have a mana capacity since birth and the mana capacity increases as their level does but the mana capacity increment is dependent on the person's class, for example, the mana increment in a mage is faster than that of a swordsman"

"How do I use or sense this mana?"

"I normally feel it in my heart, my blood"

I don't really have a heart or that much blood but I should at least try so I closed my eyes and tried to feel everything around me but to no avail.

"You know what? why don't you try learning your skill first maybe I'll get an insight if I see you use mana" I gave up so I'll just let Cynthia go first

"Ok"

I watch as Cynthia gave off a bluish light, the scroll floated above her head. The scroll slowly faded and the bluish light returned to her body.

'Lilith, report'

'Report: Cynthia's energy level rose and the said energy wrapped around the scroll. The scroll also emitted the same energy as the one Cynthia emitted, the two energy then synchronized afterward, the energy returned to Cynthia's body. End of report'

'Thanks Lilith'

"Did you learn anything Zeno?" Cynthia asked

"Yeah, could you use that [Lightning] on me?" I had an idea, maybe I can use lightning to recharge my DK mecha suit

"No, I might hurt you"

"Come on, I'm not that weak am I?" I chuckled

"Then... please brace yourself"

'Lilith, can DK absorb it?'

'Yes'

'Ok then, please do all the necessary preparations'

'Preparations are all done'

Cynthia used [Lightning] on my body, and obviously, it hurt as hell.

'DK's energy is recharging....12%....15%......20%...27%'

The lightning stopped and I only reached 27%, well at least my energy problems is now solved.
