The abyss descended, and the extraordinary beings wreaked havoc, but Qin Shan snatched the script. "Whether the world is in chaos or not, I, Qin Shan, have the final say." Reborn with a ship girl, Qin Shan raised his middle finger to the abyss.

My name is Ammons, and I'm a villain. I can modify common sense and exchange various villainous abilities through the Demon King System to create my own Demon King powers. Reincarnated from ancient times into a useless prince, this holy mage protagonist's magic is unmatched, but your fiancée is too shy~ Your master is very charming~ And there's the genius prodigy from the Duke's family, born invincible, and your sword saint maid is very alluring! What, you're actually a little loli? Well, I'll take you all! Those reincarnated old men, overpowered protagonists, heroes, etc., with me, Ammons, you'll all suffer!

I live a different world than everyone else. In other people's worlds: I am the defender of order, the hero who saves the world, the leader of the Dawn Alliance, the commander of the Dragon Knights, the chief archmage of the Knowledge Alliance, the marshal of the Federation, and a prince of both the North and South Empires. In my world: because there are no computer game consoles for me to play at home, I can only kill time by running a Crystal Palace while saving the world and playing live-action RPGs. A rough, offhand summary: This is the story of a transmigrator who thinks he's a tech geek but is actually a complete shut-in, shamelessly running a Crystal Palace while incidentally saving the world. This is the story of a loving shut-in loudly calling for love in the heart of a loveless world.
