Archmage Isadora looked at Yuan with an anticipatory expression and asked, "Do you know something about this mysterious barrier that is preventing us from entering the secret compartment?"

"I'm sorry, Miss Isadora, but this is the first time I've heard about such a barrier. If you show us the place, we may figure out what kind of barrier is blocking you from entering the compartment," Yuan lied, a sly smile on his face.
He wasn't planning to reveal what kind of barrier it was until he could guess what might be hidden inside the secret compartment.
