Experiment
On the 33rd floor of this tower, the [Alchemy lab], I was standing before a complicated piece of equipment made of glass.
Many pieces of equipment made of glass were decorating the whole giant room that was on the smaller side of the floors of this great tower.
I was making something important right now.
It has been almost a year, so I knew the 'exam' master mentioned will be here any day.
I had to do the final preparations.
Surprisingly, my proficiency in alchemy had increased considerably.
I could now process materials that even high-grade, experienced ones might not be able to perform.
But it was only possible because of this masterful equipment that made almost the entire process automatic.
Everything in this place, from the little spoon to take the material to that giant fridge, all the things were artifacts created by her.
