Crystal Palace of Heaven

I and others live in different worlds.In other people's worlds: I am the defender of order, the hero who saves the world, the leader of the Dawn Alliance, the head of the Dragon Knight Order, the chief archmage of the Knowledge Alliance, the federal marshal, and the princes of the two empires, North and South.In my world: Because this world doesn't have computers, internet, or game consoles for me to stay home, I can only open a crystal palace while saving the world, playing a real-life RPG to kill time.Rough version introduction:This is a story about a guy who thinks he's a tech otaku, but is actually a dead otaku, who travels through worlds and shamelessly opens a crystal palace while casually saving the world.This is a story about a very loving dead otaku shouting for love in a world without love.
