Tower of Immortals

Ummm i'm stuck on floor 47... there seems to be a path leading down and a path leading to the right, but none of those take me anywhere... both the paths seem to be dead ends..is this supposed to happen or did i forget to do something in the previous levels??? i also tried searching for any hidden paths on that floor or a secret switch or something but i dint find anything... plz tell me what to do.. i was really enjoying the game...
can someone plz tell me what to do coz i'm really tired of battling and running away from those monsters...... :(
