After all, he had stayed in the library Pavilion for a full three years. He didn't need to go out to know about the world. Although Yu Zhe wasn't an Alchemist, he still knew a lot about these things.
As far as he knew, there were only a handful of alchemists in the entire history of the sky-class five islands who could make a high quality foundation-breaking pill. After all, someone like Zhang Liju was a once-in-a-century genius, and no one else could compare to him.
Normally speaking, being able to make a high-quality foundation-breaking pill was already very rare in the world of alchemy. Looking at the entire Sky Class island within an island, there weren't many alchemists who could do this, and the North Island's own pill Hall couldn't even make it. As for the legendary Supreme-grade foundation-breaking pill, that was purely a dream!
