The Day of the Exams

"Hello, old friend." A senior-looking professor shook the hand of a wrinkled old man. The wrinkled old man panted as if he had run recently. He was the one who had witnessed Jason's potion-making before, and with his friends, he had come to meet his good friend.

Everyone in the room got seated. The room had tall bookshelves that had books on potion-making, potion effects, and other science-related things. The professor had also put faded yellowish parchment papers on the walls as decoration.

"Why have you come today in this nice evening?" The professor asked as he looked at the four people seated opposite of him. The three friends looked at the wrinkled old man.

"I met a person in a potion-making store today." The wrinkled old man spoke and interlaced his fingers. "He concocted a perfect potion."
