One day in the underground life, where the place is so dark and hot, a man escaped with his assistant. He is the 900th demon king, or his real name is Yang jungwon.

"Are you serious sir?, wouldn't being a demon king be amazing?" asked his assistant named Jake.

"I don't understand why you all want me to be the 900th demon king, this world has been spinning for thousands of years, haven't the demon race always lost?" Jungwon rolled his eyes.

Jake was silent for a moment, "You are still destined to be the demon king. I have taken care of you since you were little, you even followed me from my nipple." Jake wiped his eyes dramatically.

Jungwon immediately put on a nauseous face "stop saying that rubbish Jake"

They arrived at the bottom of the earth where the human race lived. Jungwon was amazed to see the scenery, "What is that thing called the sun? Then what is this flying creature?" Jungwon saw a butterfly perched on his shoulder.

Jake glanced at Jungwon "That's called a butterfly"

"The human territory is quite good, hmm, I wonder why wars always happen, even though we can live with what has been provided," Jungwon asked.

"I can't answer that, the world has so many secrets even though I've lived for thousands of years," answered Jake.

then suddenly jungwon saw a woman in a golden dress running being chased by goblins, it was you, you disguised yourself as an ordinary human woman .

"Sir, help me, I'm being chased by goblins!"

Jungwon looked at you "hmm?, okay the price is cheap, 2 gold coins for our first business miss" Jungwon smirked, yes Jungwon is rich but he is always cunning
