The Floor of My House Leads to Hell

Zhao Xiuxian gets so carried away playing a mobile game that he kicks through the floor of his home.

Looking down, he sees a giant mountain of flesh, as huge as Mount Everest, opening its enormous mouth and roaring below.

Zhao Xiuxian silently covers it with a rug, then lies down to sleep. He'll feel better after waking up.

The next day, after a good night's sleep and a hearty meal, Zhao Xiuxian starts up the robot vacuum and keeps charging around the canyon.

After happily reaching one star in the King tier, he turns around and discovers the robot vacuum, rug and all, has vanished from the living room.

From the pitch-black hole, the dark mountain of flesh is wriggling its way upward...

When they first meet,

Demon King: Aaaaaah! I'll kill everyone! I'll destroy this world!

Zhao Xiuxian: *sobs*

After they've known each other for a while,

Demon King: *sobs* They bully me every day.

Zhao Xiuxian: There, there~ You should study hard and broaden your mind. Then you'll learn to think for yourself and stand on your own two feet!

Demon King: *sobs* They bully me because they think I'm ugly.

Zhao Xiuxian: In this day and age, can anyone even be ugly? What would that say about modern technology?

Demon King: *sobs* They suck my blood every day and dump garbage on me.

Zhao Xiuxian: You have to understand that energy is conserved, blah blah blah. In short, you haven't lost any energy at all, so you don't need to be angry. Love and generosity can make the world a better place~

Demon King: That sounds pretty reasonable, hehe. (Frees himself from his restraints while rubbing his fists together. He didn't hear the second half at all.)

P.S. What do you do when the Demon King becomes educated?
