What if You Had Soap During The Black Death?

What if you had soap during the Black Death? Day one, you arrive in London carrying a strange pink brick and slam it onto a plague doctor's table. He poaks it as it might bite back. You strike a deal and take over his shop for the night. Bubbles everywhere. By sunrise, you've made a mountain of clean, scented soap. Day three, you walk into the town square. A local doctor shows up with a creepy bird mask and a large ego. He rubs a smelly onion on his arm to stop the sickness, but the dirt stays put. You use water and your pink brick. The grime melts away like warm butter. He doesn't even have a single flea. Day five, words spreads across London and crowds gather around the shop to watch the strange blocks make foam. Merchants begin arriving with carts of alkali and oils from across Europe. A quiet traveler in a philosopher's cloak pushes through the crowd and asks if the soap is your power. What are you without it? You take off his disguise. It's socrates. You tie him up and ship him back to the correct century. Day seven, the King of England sends soldiers to your shop with a request. Hope for the Kingdom, soon clean hands fill the hospitals. City builders start making real baths. You just ended the black death.
