Okay, now you are standing in front of an open entrance, go straight towards the wall through that open entrance. Now slightly turn to your left and move towards the open entrance, which is on the right side. Now you are facing towards the wall, turn to your right and walk straight in the corridor until you reach next to a staircase, which is on the left side. Now in front of you there is a narrow path, walk straight in the narrow path until you reach next to an open door on the right side and this is the end point.
