Su Zhi was born in Yunjian Sect and knew how rare it was to obtain a top-quality Foundation Establishment Pill. Even the Second Elder in Yunjian Sect, who is a first-class second-grade alchemist, had only managed to produce a few of these after so many years.
Possibly, one in every five or six batches of Foundation Establishment Pills might randomly yield a top-quality one.
However, in the Yunjian Sect, only those privileged direct disciples could request such top-quality Foundation Establishment Pills, while others didn't even have a chance to exchange for them.
Initially, Su Zhi didn't have high expectations for how many Foundation Establishment Pills Su Yu could make. She would be satisfied with just a single common-quality pill.
But now, as she looked at the two top-quality Foundation Establishment Pills and two common-quality Foundation Establishment Pills in front of her, she realized just how incredibly talented her younger brother was in alchemy.
