Just when he thought he had become a little cabbage that nobody wanted and no one would ever spoil him again, a certain ancient monster of a National Teacher who had lived 1,000 years appeared again… and looked to be doing quite well for himself.
The utterly impoverished little emperor had tears in his eyes: “Beloved subject! I have missed you so much!”
National Teacher: “Your Majesty, this minister has waited for you for a thousand years.”
