The Pill Forest Academy consisted of four buildings - A, B, C, and D buildings, each representing a different rank.
The lower-ranked disciples could only study in D Building, middle-ranked disciples could access C Building, and the upper-ranked disciples had the privilege of studying in B Building.
The highest-ranking building, A Building, was reserved exclusively for a handful of True Disciples.
Apart from these four buildings, the academy also comprised several other temples and annexes. However, the four main buildings were the most significant in ranking and hierarchies.
Fang Lin had the privilege to access the Pill Forest Academy freely for a year, but since he was merely a lower-ranked disciple, his limitations meant he could only stay in D Building, his status did not qualify him to enter the other three.
