Chương 285: Mid-Term Exam [3]

Without glancing at the portal, the professor glanced towards his tablet and said

"F ranks, off you go…"

-Vuuum! -Vuuum! -Vuuum!

Right at his words student with <F> ranked began to enter the dungeon. It takes a maximum of four minutes before all of the students enter the dungeon.

After seeing that everyone had entered the dungeon, the professor nodded his head and said

"Good, now increase the dungeon level difficulty to <E> ranked."
