-First Room-
There are seats sitting in rows, five by six desks perfectly arranged in such a huge room. The room is enclosed and can only be locked from the outside. The windows are nailed shut with bricks glued along the glass, making it impossible to break out in any way. There is a note written on the board : The only way to get out, is to find the answer to the question written in blood.~ Entrapped in a treasure chest is full of gold waiting to be free, the only way out, has no in. It has no keyhole, and it has no cracks. What is it?
