The teaching of Xuan Yi was completely different from the teaching of the other teachers.
In addition, Xuan Yi was only twenty-four or twenty-five years old. He was not much older than them, and might even be a little younger.
Being able to sit down and listen to Xuan Yi's lecture was already the limit of the three of them.
As for Xuan Yi's teaching level, it was very easy to understand since he had the alchemy memory of a seventh-grade pill king.
However, Xuan Yi was talking about the refining of first grade pills, and the three of them were at least third grade alchemists. They felt that they were not very strong, so they could go up to them.
After they went back, whenever the three of them tried his method, their skills would increase to a certain extent.
This time, the three of them were completely stunned.
"Have you guys refined pills recently?"
