"Come this way," the emperor called out, "you'd best take off your shoes, they're covered in dust and bacteria. Microorganisms in the atmosphere are always tougher than us multicellular beings."
That tone...
A maid next to him stepped forward to remove Yang Ming's shoes, but he declined with a gesture.
Yang Ming smiled as he crouched down, removing his shoes and socks, and said softly, "Simplicity brings purity; the more complex a life form is, the more fragile it often is."
"You know biology?"
"A little," Yang Ming took hold of the topic proactively, "In my previous line of work, I had to touch upon various academic subjects a bit."
"Oh, come this way," the old emperor beckoned to Yang Ming, leading him toward a side hall filled with collections of various heavy metal artifacts, "Today you have plenty of time to tell me about your adventure stories, they sound quite interesting."
Yang Ming laughed, "There's a reward for this, right?"
