Chen Xing is transported to another world.
He becomes a hero and fights the Demon King.
Well, he's already here, so he might as well.
Ten years later, the Demon King's castle collapses.
Chen Xing dusts off his hands, waiting for the System to tell him, “Quest complete. Returning you home.”
But nothing happens.
He opens his eyes and sees buildings glowing along every street, metal contraptions flying through the sky, and glowing bands on everyone's wrists.
A thousand years have passed.
The other world where he once worked has developed so much he can barely recognize it.
And the most absurd part is that the world he saved now calls him the true Demon King!
Chen Xing squats by the roadside, his stomach growling with hunger.
Whatever. First, he needs to find somewhere to eat.
As for getting home…
He's already waited ten years. A few more days won't matter.
