"Speak more clearly," Noan said, frowning.
Monica nodded, then said, "At first, we searched around, but within fifty miles of this city, there was nothing but snow."
"That's why everyone—including myself—believes the secret must lie within these walls. Even though the System's mission is no longer in effect, we continue searching for that secret."
"Everyone thinks that if we uncover and resolve that secret, we will be able to leave this 'Challenge Realm.'"
Noan nodded and pressed on, "So have you found any clues yet?"
Monica sighed and shook her head. "Not yet, because none of us has been able to enter that castle."
"Why not?" Noan asked, brow furrowing.
"Because its gate is frozen and sealed with magic," Monica explained. "Every path leading inside has been shut off by the seal—no one can get through."
Hearing this, Noan was not surprised. If they had entered the castle, they would have discovered its secret and taken control.
