Two reptiles had been swimming in the same direction for a long time, and suddenly the water density decreased sharply; somehow, they ended up in a small underwater cave, near one of whose walls sat a suspicious-looking man in rags, holding a staff. The fact that there were two non-humans here clearly didn't please him, and he stared at them with a stern look.
--"Respected sir, may I ask what business you have here? Do you need any help? It's not every day that you meet old men walled up in an underwater cave."
