[At least he's got some plan ahead of time and didn't go to the smashing down walls part. Ranma can't imagine that these cottages come cheap and that the guys here can afford knocking it entirely down and rebuilding it from the ground up. Not unless they want to stay in the ship's quarters as a permanent residency. It just reminded him that he should probably try looking into finding himself a place to stay, even if the ship's beds are incredibly comfy.]

You got to start somewhere, yeah. [His blue eyes fell upon the sledgehammer in the green teen's hands.] That hammer's good and all, but how about you stand back and I show you how a pro does it?

[If you count 'accidentally breaking through walls while being hunted down by other martial artists' as being a pro... But here, he's doing it on purpose! If he's good at breaking things by accident, then he should be an expert at doing it on purpose!

Ranma got up close to the stone wall, continuing to get a good feel of it. Then all at once, he reeled a fist back and delivered a straight punch into the center of the wall. The result? Every individual stone making up the wall cracking and crumbling on by one into rubble and dust starting from the large hole Ranma put through it. He was careful not to do any more damage than what was intended. Izuku'd probably be pissed if he took the entire house down with it.]
