Despite being a Rank-1 elixir, the Qi-replenishing Spirit Water was challenging to concoct.
The recipe was written on the glass bottle, but only cultivators from Jumang Daoist Academy and Imperial Medical Academy knew how to make it.
The young girl in the white nurse uniform didn't go to college just like Chen Mobai, so she probably didn't extract and mix it herself.
Chen Mobai recalled his purchases at that pharmacy.
The girl mentioned having a master who was an alchemist.
It was probably her master who prepared the spiritual water. She merely helped with the final bottling process, which he had witnessed.
Chen Mobai speculated in his mind.
He picked up the empty glass tube and put it into his backpack.
Then he took out the needle box.
He had possessed this magic artifact for over a month. After discovering that it could be controlled via magnetism, he had spent most of his free time in school's Cultivation Room studying it, outside of reading and studying.
