As the God of War Peter walked towards the Federal building, Callie had followed the old butler to a hidden residence. She had never heard her grandfather mention this place.
There was only a very ordinary room behind the old door. Callie saw the butler open the door for her, revealing the furnishings in the room.
Other than a simple desk and chair, there was also a cabinet filled with books. Callie entered the room and looked around, but saw no sign of her grandfather. She looked at the old butler with a puzzled expression.
After the old butler entered the room, he immediately closed the door and hid behind the window. He seemed to be observing something through the window.
"John! Where's my grandfather? There's no sign of any human activity here!"
