Lan Ruo was lost in his thoughts for a moment before he frowned. "Though it's indeed not bad… Why is there an underground passage here? They are all dead ends and don't go anywhere, and there are even beds in the underground passage… It looks to be just an emergency place of refuge?

As expected, Lan Ruo had already changed the topic the next moment. "The passageway is still locked?"
