Arthur wasn't nervous like the others, he had always wanted magical powers, in his world he wanted to be powerful and in this world he was fascinated by beyonder powers, besides he roughly knew the chances of surviving the advancement, so he wasn't worried.
He received the potion formula
Sequence 9 Spectator:
Main ingredients:
Matured Manhal Fish's Eyeball.
35 ml of Goat-Horned Blackfish Blood.
Supplementary ingredients:
80 ml of Purified Water.
5 drops of Autumn Crocus Essence.
13 grams of Cow Teeth Paeonol Powder.
7 petals of elf flowers.
He took the petals and the powder, no change occured, then he dropped the essence in causing it to mix into a blue liquid, then the purified water which turned the jelly like substance into a liquid, he then added the blood turning it into a red liquid, then the eyeball it turned into a sticky silver liquid filled with countless bubbles, creating a serene atmosphere.
Then he waited for the divination and then drank it without hesitation, forgeting to pour it into a cup.
He felt nothing for a moment, the headache hit him he felt as if his head was going to crack apart, then with the courtesy of cognitation, the gray fog and his own resilience he survived.
