There were multiple challenges that one had to go through; the first was to check one's cultivation base. One needed a minimum of the Acquired Realm, Sky Tier, and Mediate Layer to be allowed even to try the other trials.
Then there was a trial that tested one's understanding of their martial art techniques. You could pick whichever technique you wished to test for, but if you did not show a satisfactory display of control over the technique, one would be removed.
After this came the fighting test. Although one could control their techniques and had a decent cultivation rank, the most vital thing to stay alive was their battle ability. So these people would be sent to train against beasts.
The Blue Water Institute had brought more than ten thousand beasts with them to the trial grounds
