The gods gilded the outlines of desire with seven kinds of radiance, proclaiming that their authority could be reached.
Yet above the gods, "Heavenly Principles" gaze down upon the mortal world, extinguishing and rekindling the sparks of civilization time and again.
Witnesses came to bear witness, and Recorders were born to remember. But Su Bai knew that he had always been a participant.
He traveled all across Teyvat, unearthing one secret after another from deep within the land. At last, Su Bai raised the banner of rebellion against the sky:
"Humanity's fate should not be dictated by a false sky!"
"Do the gods consider some mortal wishes more worthy than others?"
"Humanity will endure forever, even if that means defying the 'Heavenly Principles'!"
As a mortal, Su Bai drew his sword against the sky.
Behind him, the flags of humanity flew across the seven nations of the mortal realm.
P.S. This is probably a story about someone who wasn't a hero, but became one. The protagonist has no System or cheat abilities. It follows the worldbuilding of Teyvat alone.
