Evolution!

The staff member led them to the bottom of the arena, and there they discovered that there were eight A.I. computers installed on all sides.

The staff member pointed towards the A.I. computer beside him and began to explain. "The A.I. has entered the list of seniors who are evaluating you. Whoever is ready can freely choose the senior that they would like to fight. Once you have chosen, the virtual screen at the top of the screen will show the time of the fight." As he said all this, the staff member smiled and patted the A.I. computer beside him. "Of course, these A.I. computers will also show the time. The preparation time for each evaluation is 3 minutes. If you still haven't gone up to the arena after 3 minutes, then that means you've failed the evaluation. Remember, don't go over the time limit. Our boss will definitely not give you guys a second chance."
