To the southeast of the martial arts course was a corner hidden away by a tree that was dozens of meters tall. 

There, a seven-floor building made of reinforced concrete and as thick as a fortress was covered by mutated Boston ivies. Some vines came out of a window, which made the place look desolate. 

It was once the main lecture building for the martial arts course. 

There were seven floors above ground and three floors underground, which served as the martial arts course's research labs. 

Later on, Agricultural University grew to power and became the Monster University. It obtained monetary and resource support, and it built more lecture buildings and research labs that were bigger and more lavish. This place was slowly emptied out and turned into the refresher course student's dorms and classrooms.
