The following magic core are to be enhanced by Alfin

Her own magic core in her staff which made up of a pegasus magic core which will be enhanced with the Chimera golden frog magic core. Since the chimera golden frog magic core is a naturally occurring di-element magic core, Alfin will also enhance it by using space magic core and also the dust Vulture magic core

Aurora Ice Queen magic core which needed repair first before anything else

Fizumi and Azumi magic core, the one that they manage to get their hands on during the slime snake attack

Lastly, magic core for Kucin and the students weapon as a thank you gift for them for helping out in Mesembryanthemum

"That's quite a lot of work to do" [Filaurel]

Filaurel look in amazement as Alfin keep on adding stuff to her table one after another and showing no sign of stopping. From the magic core that will be enhanced to numerous number of magic stone, magic paper and ink with affinity to the elements they are made from. 

"I guess we should start with the hardest one" [Alfin]

Alfin said that as she hold the magic core for Fizumi and Azumi

"I'll help" [Fizumi]

"Naturally" [Alfin]

"Such devilish smile" [Aqua]

"If I am the only one doing it, who knew how long will it take" [Alfin]

"Gulp..." [Filaurel]

"Let's get started" [Alfin]

First, Alfin bring out another large table from her item box, with one of the giant slime snake magic core which she put in the centre of the magic core. Next, she put 7 other smaller magic core surrounding the giant slime snake magic core

"That's is..." [Filaurel]

Filaurel look in amazement since Alfin manage to get quite a quality magic core, it's a B rank magic core without a single doubt

(Just how much did she spend for it...) [Filaurel]

With the core in its place, Alfin begin to draw a magic circle in the magic paper. She started with the fire magic circle, where she drew a perfect circle by using the fire ink into the fire paper, with the little fire magic affinity she have, she pour it to the fire ink so that the quality will be further enhance, she also wrote a number of spell included to further increases the chances of success

(This should do it) [Alfin]

After finishing the circle, he place the paper just underneath the centre of the fire magic core. She then placed numerous pebble like structure, which is just a fire magic stone, surrounding the magic core but still within the magic paper. She then connect each of the magic stone in one circle with the magic ink before merging it all toward the centre of the paper

"Should I enhance it now?" [Fizumi]

"Not yet, I would like to enhance all the magic core involved here in one shot" [Alfin]

"!" [Other]

"That's quite a difficult task to do" [Filaurel]

"But the resulting product will be magnificent" [Alfin]

"Are you sure? The failure rate is quite high" [Aqua]

"Pretty sure, plus..." [Alfin]

Alfin look at the giant slime snake magic core

"It's a gift for him, for always be there with me, I will make it a success!" [Alfin]

(Will both of them realize that they are in love with each other) [Filaurel]

Alfin then began to do the same for the Water magic core

"Let me handle that one, my affinity toward water will affect the quality of it" [Aqua]

"Please do" [Alfin]

"Then I suppose I should do the mirage element" [Filaurel]

"I will do the wind and earth part" [Fizumi]

"That will leave me with the space and time then" [Alfin]

One by one, they begin to draw the magic circle, while drawing it, they further pour their mana to the magic ink just like what Alfin did just now, and when all the magic paper have been drawn with the magic circle, Alfin then bring out 7 fresh set of magic ink compromise of each element and begin to mix it together

"Can you guys please pour your mana in it" [Alfin]

Knowing her intention, they easily agree to it

Alfin then connect all the magic core with a circle using the magic ink that have been imbuded with everyone mana and as a final process, she drew a large magic circle underneath the giant slime snake magic core

"hmmm...." [Alfin]

Unhappy with it, she then take 7 extra sheet of magic paper of different elements, draw each one of them with magic circle and stack it on top of each other before finally putting it right underneath the magic core. 

The final process of this involves her connecting all the magic circle together so that the flow of mana during the enhancement won't go hay wire

She proceed with care

"Right!" [Alfin]

"Such complex magic circle..." [Filaurel]

"And I believe Fizumi should be the one that will enhance the magic core all together?" [Aqua]

"Correct!" [Alfin]

"Got it! Will do my best for master" [Fizumi]

With that, Fizumi pour out her mana comprising of each element into the magic circle, activating each magic circle in the periphery first so that the magic core will absorb the magic stone power. The other help her by supplying their mana as well as helping the process by pouring their mana into the respective magic core

With all the seven magic core successfully enhance with the magic core, now come the hard part, bringing the 7 magic core power to the centre.

Fizumi slowly push the magic core power to the centre, and once each magic core power arrive simultaneously at the centre, she integrate the power of it into the giant slime snake magic core

"Uhh...." [Fizumi]

She can't help but to let out the strange sound as the precision needed is high, but slowly and surely, the power of the magic core increases and finally

"You did it!" [Aqua]

"That's a hard process..." [Filaurel]

"Agree" [Fizumi]

"Judging by its power, I say we got ourselves an A grade magic core of the 7 element!" [Alfin]

"I can only imagine the ruckus each country will made when finding out that Azumi will have such powerful magic core at his disposal" [Filaurel]

"Yeah, and the amount of them that will spend crazy amount of money for it also" [Alfin]

"And Fizumi will also have her own magic core just like this" [Aqua]

"Let just hope everything will be fine" [Filaurel]

All of them have a tired look in their face

Alfin look at the clock and a total of 7 hour have passed since they begin. Alfin then bring out another table with some nutritious supplement with it

"How about we take a break first before continuing further" [Alfin]

None object to the suggestion
