So, I am wearing Rachel's used lab coat, stained with only God knows how many chemicals, red, green, or even yellow. Still, it has been washed thoroughly and I'll assume this is just a dye stain since I doubt a child as old as I am back then will be allowed to mess around with pyrotechnics. I also have a piece of cloth wrapped around my mouth and nose.
"Well, the mentee of the famous gunsmith, the fastest shooter of Ferrett's estate, what can I do for you?" Ostwald jokes as he prepares the ingredient for me. He prepares a bottle of liquid mana, some of the guncotton that Rachel creates, alongside acetone on the table. He also brought out the petroleum jelly that I ask him to bring.
I tell him the precise ratio to make a smokeless powder. Of course, he asks where did I get the ratio for this pyrotechnics, I answer by saying that I got it by reading something in this big library whose books collections are probably just for show instead of knowledge.
