Continuation
You stop at a cliff with a tree on it, realizing that continuation is impossible unless you find some way to bridge the gap to the other side of the cliff. The tree seems long enough to reach to the other side, but how are you going to chop it down?

Continuation is impossible unless you chop this tree down to use as a bridge to cross to the other side of the cliff. You decide to use a wrecking (れき) ball. Luckily, there’s one right by you. So you take the wrecking ball and knock the tree over, making a bridge with it.
