The gods died ten thousand years ago, and their divinity scattered across the mortal realm, becoming a flame fought over by noble clans and the Directorate of Celestial Observations.
Lu Jintian, a boy from a forsaken land, was born without any affinity for the divine. But on the night Uncle Lei, the shrine keeper, was killed, he swallowed the blue flame of a divine vessel.
The court branded him a demonic seed and placed a bounty on his head. Yet every time he devours a wisp of divine fire, he sees a piece of the truth about the gods' deaths, a truth someone erased.
Why did his father die in the rift in the sky? Why did the gods willingly meet their deaths? And why does the thing sealed away for ten thousand years keep calling out one word: "Repay"?
When Lu Jin followed the unfinished road his father had walked and reached Luojing, he finally discovered that what he had swallowed was never just fire. It was an old debt the gods owed to the mortal realm.
