"Team A, commencing the plan!"
"Lumos!"
The first team (Team A) comprised of over 30 students. Those 30 students are all equipped with at least high athletic capability. And exactly as planned, the examinees were able to lead a large number of cyclops into the dead end.
Team B, on the other hand, consisted of fifteen students that followed the monsters stealthily. These fifteen students have a high affiliation with fire and earth.
They were tasked to wait until the perfect timing so they could trap the cyclops into the dead-end; and once they are contained, both teams could commence the next phase: kill as much as possible until Team C gives the signal that indicates they have solved the riddle and found the exit.
