For him, Zhou Lingyin's identity jade was a trump card, in case he was ever besieged by a demon, he would have a way to turn the tables.
It seems that this trump card cannot be preserved now.
Having figured out the method to deal with the demon, he thought of another question: "Senior, I found that there are five back doors in Kun Tian Prison..."
Su Nan told the story of his discovery, finally asking, "What is the great princess trying to do by setting up a passage in her own bedroom?"
"Five back doors?" Zhou Lingyin was startled, clearly not knowing about this.
However, she quickly thought of something and whispered, "It seems the rumors are true!"
Su Nan became interested, "What rumors?"
Zhou Lingyin was silent for a moment and said, "If I'm not mistaken, the great princess probably wants to completely control the Kun Tian Prison."
