Ying Su, the prince of the Dragon Empire, is a martial arts idiot, but he knows the last move of the "Underworld Emperor Technique" that no one else can learn.
After the king disappeared, the prince embarked on a journey to find the "king's token".
"Yingsu, why on earth do you want to participate in this 'King Trial'?" Liuli asked him.
"To be an ordinary emperor."
…
Many years later, a person asked the later Emperor Pluto:
"Yingsu, did you ever regret your decision?"
Hades answered her: "Never."
She then asked: "Even if the result is like that?"
The Hades Emperor smiled and said:
"Even if the result is like that."
