The head instructor began the presentation of the third trial, he said with a clear and loud voice: "This third trial will take place in two phases, we will first test your perception, this phase will be fast and will eliminate a large number of all of you.
It will take place ten by ten and will last three minutes each time, the participants will enter a room and leave by another exit, so no one will be disadvantaged by the order of passage.
The second phase will not be eliminatory and you will be able to earn a large number of points if you are good enough, it will be a test on your endurance and the management of your spiritual energy, this second phase has no time limit, it will stop when we have a winner.
Don't worry too much this shouldn't last more than a few hours.
That's all for today! You are all dismissed."
