The entire Trial Arena is protected by a Formation, and without the permission of the teachers who guard the arena, no one can enter without authorization.
This serves as a protection for disciples like Ye Fan who cultivate in the Emperor's Secret Realm, because once the Array Patterns are activated, re-creating the Peak Combat Power of Xuan Beasts or human-shaped creatures could mean the young disciples entering might not be opponents.
The teachers responsible for monitoring the Array Patterns must constantly keep an eye on the battles in the Trial Arena, and in case of any dangerous situation, they can quickly restrain the Xuan Beasts or human-shaped creatures to ensure the safety of those who enter.
Ye Fan arrived outside the Trial Arena and saw an Elder Gu with white hair and beard basking comfortably in the sun, intently reading an ancient Beast Skin Book, completely oblivious to Ye Fan's arrival.
