To Gu Lili's surprise, after walking forward for about twenty meters, Su Changzhi glanced around, locking his gaze on one empty cell before stopping.
"What's going on?"
"Follow me." Su Changzhi led her through the threshold of the cell, stopping a meter from the wall. He whispered, "This wall is a secret room. I've been to Second Brother's dungeon before, so I know this. My mana isn't strong enough to open it, but yours definitely can."
Without saying a word, Gu Lili followed his instructions to open it, and sure enough, there inside was a hidden passage.
"How do you know the secret passages of your several brothers?" Almost every secret room was revealed by him.
"Know your enemy, know yourself."
"Do you know the secret room in Seventh Brother's residence?"
"I do. There's nothing much in his secret room. He's been absent from the residence for years."
"You're really something."
