Dream Realm.
This is an independent realm that is under the God of Dreams. Thanks to the connection of Xia Jieye to the new God of Dreams, he was able to control Warden Lou's dreams and show him his past life and let him once again experience what happened in his past life. Though helping his subordinate is just a side case, his main case is bringing nightmares to his other self for making their beloved cry.
Xia Jieye spoke, "Stay here and experience your past life. You will wake up in reality after you have seen everything that needs to be. Your connection with that child called Ming has been longer than you think."
He disappeared in thin air as he did before. Lou Wuye had no other choice but to undergo the events that would happen in this dream. He could still recall the blushing face of that child named Lou Ming just now. Since he couldn't leave this dungeon, he can only stay for now. He wouldn't die in this place anyway.
