if you already got in the hellhound village luoyang is blocking a barrel on the left and yimu is starring at the bones on the right of the village. i had to start up the game to find out. my minds not fully there, i had not had my morning strong coffee yet.
oh there are portal in the dungeon that you need to step on to go to different parts of the dungeon to find the exit to the village. basicly walk around that dungeon. when you find the village entrince and go through you will get a cut scene. there are only three maps to that dungeon so you just have to remember its layout or draw a map yourself. but fare warning, the traps, portal, and chest get ranomized to set places every time you enter it. fare hint the entrince you need to find is in the top right of one of its areas.
