If you burn the stove with wood and ember at the same time it will burn much quicker,so the key is very simple--just stay there until the water boils.
I might have missed something, but there is no wood in that room? Am I carrying it?
Could you tell me the exact level?
Hints
Intro just burn them all
level1 only burns sofa
level2 burn sofa to pass the heat
level3 burn through the wall（please stay still for a while，cuz I wanna show you the heat can be plused
level4 burn the sofa and enjoy the show
