Nathan was up in the middle of the night. He saw Eve sleeping soundly in her own bed. Nathan slowly got up from the room to his father's room. He was very curious about the covenant in the Roman language. Nathan wanted to translate immediately. Arriving at William's room, there is a statue beside the bookcase. The statue is a statue of a princess holding a window frame. Nathan had seen his father turn the frame. That's why he had the initiative to imitate her. Nathan gently pressed and turned it, as he expected the bookcase turned to lead Nathan to a hidden room. In the room there is a staircase leading to the lower floor. Nathan looked for the switch to turn on the light. When the room was filled with light, Nathan could see the walls of the room were almost full of books. Hi
