Thinking of this, Su Nan's eyes lit up, and he eagerly followed the passage downward.
Just over two minutes later, he arrived at the door.
The prison door opened to a bare cell.
The cell was empty, no demons in sight. On the opposite side of the room, an identical prison door stood.
Without needing a second guess, Su Nan knew what waited beyond the door – the corridor of Kun Tian Prison!
"Kun Tian Prison actually has such a place!" Su Nan was pleasantly surprised.
Not long ago, he was racking his brains trying to escape from Wolf King Palace. Unexpectedly, not only has he left the palace, but he has also managed to return to Kun Tian Prison, evading the demons.
Upon entering the cell, he found that the back door was very well disguised. Once closed, it blended perfectly with the cell. If you didn't know there was a door there, you'd probably never consider it.
