"Can you really diagnose illnesses without any instruments? Is it that magical?"
"Didn't ancient practitioners of Xia medicine diagnose patients without instruments? They managed just fine, though not as precise."
"If it weren't for Teacher Lei, and it were someone else, I'd really think it was a setup."
Ignoring the students' bustling discussions, Yang Yu continued, "I could have given you a few acupuncture needles, and you would have seen immediate effects, but to prove the efficacy of the medicine, you'll have to endure a bit, Director Lei."
The herbs Yang Yu requested were quickly delivered, together with items such as an oven, an induction cooker, and a small gas stove.
Yang Yu first boiled some herbs on the induction cooker and gas stove, then took them out, crushed them, rolled them into the shape of elixirs, and put them into the oven.
Minutes later, several elixirs were formed, just as Director Lei's headache reached its peak: "It hurts, it hurts!"
