How can I find the hill and go to kill the monster

I'm stuck in the game cos the wizard asked me to kill the monser. He said that the monster in up on the hill in the cave. However, I can't find it. Beside, I have no coins to cross the bridge.

Who can help me to find the monster?
Thank u !!

listen,i'm just giving u a rough idea. go upwards from the bridge till u come to the edge of the plains , then walk along the edge. i think after a couple of scrrens u'll see a big stone. push it. secet entran ce. go in . find monster. kill
