Rong Shu is an awesome nine-tailed fox.
I took on an apprentice a thousand years ago.
The apprentice turned around and became the Demon Lord, fighting back to the right path.
Thousands of years later, he accepted another apprentice.
The apprentice turned around and became the Demon Lord again, wanting to marry the master.
Rong Shu: "..."
Wait, that's not quite right...
Rong Shu: I can't afford to offend him, I just slipped away.
