Dong Tianyu's inquiry to them wasn't a test, for as a practitioner at the Golden Core Stage, Dong Tianyu had already found a method to impose restrictions on others within the Scripture Hall.
If any of the Canaries felt weary and wanted to leave the Cave, Dong Tianyu, considering the time they had spent with him, might allow them to leave the Cave.
However, before leaving, Dong Tianyu would definitely impose restrictions on their souls, so that whether willingly or unwillingly, they would be absolutely unable to share the details of the Cave with outsiders.
Perhaps it was those Canaries who yearned for freedom that had already secretly left the last time an opportunity arose. Those who could stay had long since let go of any thoughts of departure.
So now, when Dong Tianyu took them out for a stroll, he no longer asked if they had the desire to leave the Cave.
