Remember that little old miner dude Ryoga learned the Shishi Hokodan from? What if he came to check out the situation, after the big fight with Ranma at the end of that story arc? He's got enough skill to use ki on that level, even if he didn't consider himself a martial artist IIRC. He'd probably also be dissappointed in Ryoga for using a technique of desperation intended to save lives during a cave-in as a weapon, but absolutely furious with Ranma's revision, that turns it from a last resort based on despair, so it can only be used to full effect when you're sure you're going to lose, into a tool of conquest based on confidence, that can only be used when you're sure you're going to win. Looked at that way, it's actually even more reprehensible than Genma's Thousand Fist techniques, developed from the tactics of a sneak thief and a marauding thug respectively. Given that he's a little old teacher from a martial arts comedy manga, he'd be sure to have some "teachable moment" worthy punishment to inflict, and almost anything that breaks the Prime Time Directive in Ranma 1/2 (without being "add more of the same" I mean, since that's pretty much part of that property's PTD) is better than canon.
