The job of killing insects is more tedious than the students imagined.
Due to the ban on many forms of magic in the Hundred Herb Gardens, a mechanical sprayer is used to apply the potion. Students were divided into pairs, first picking up sprayers from Old Man Sistanda and then collecting undiluted magic potion from Professor Li Qihuang.
The dilution process needs to be done by the students themselves.
With a dilution ratio of one thousand to one thousand five hundred times, they use the snow water stored from last winter, and stir clockwise with a glass rod for one minute, stirring speed should not be too fast—just ensure the liquid does not splash above the surface—Professor Li will carefully check each group's dilution results and add a drop of Earworm secretion to the diluted potion box, continuing to stir for another minute.
"I think just thirty stirs should be enough."
