Prince Woon looked around then his gaze stopped at a roll of chains that were near the stairs. It seems that the chain roll was once connected to an inner gate that no longer works now. The chain is used to pull the door and lift it so that the road can be opened.

             The prince walked towards the chain roll then held and watched the object closely. He pulled the chain from his roll to find out how long the chain was. The length of the remaining chain turned out to reach about twenty-seven meters. Actually the original length of the chain is much longer than it is now....
