Mu You soon began regretting that thought, because the first potion had been the easiest. Each one after it was harder than the last.
The medicinal properties of the second and third samples had both been badly damaged. Only after studying them for a long time did Mu You match the ingredients for both, relying partly on guesswork.
From the fourth sample onward, the damage to the residue increased further. This time, Mu You ultimately failed to identify them accurately. Twice in a row, he misidentified one ingredient, sending his conclusions completely off in the wrong direction.
"Three right, two wrong. Passable..." Vivian shook her head, but did not discourage him too much. She had personally watched his progress in Potionology and knew his level well. All she could say was that this assessment really was rather difficult. No wonder no one in the Magic Potion Club had passed it in all these years.
After tidying the table a little, Mu You opened the last bottle, hoping to at least finish on a good note. Even if he could not identify all its ingredients, he at least hoped not to be as wildly wrong as he had been with the previous two bottles.

Mu You did not stubbornly keep trying. He brought the powder on the
