"I, Qiao Lin, the most talented alchemy scholar in centuries, concocted the elixir of immortality all by myself to benefit the world. And the woman I happened to pick up on the road turned out to be Her Majesty, the Underworld King."
"I, Meroxi, have ruled over the Underworld for countless years. I was gravely wounded while tracking down an immortal who had escaped the Underworld, and someone picked me up. I never imagined he would be the mastermind behind creating immortals. I'll have to keep a very close eye on him!"
