I run a bathhouse in the Ming dynasty, heating it with nuclear power and using magma for the hot springs. We scrub people with rolling stones. After the old man next door gets scrubbed, even the eighty-year-old lady blushes and says it's wonderful! The reason young Zhu sneaks out in disguise is that he wants to get scrubbed. He uses this to strengthen his soldiers, and they take down all six kingdoms! From then on, this place becomes a sacred site under the Ming dynasty's special protection. Tickets cost two taels, and no credit is allowed!
