When other people encounter demonic fire, they fall to their knees and pray to the gods.
When Lu Heng encounters it, he first asks why the flames won't go out.
Others think a locked-room murder must be the work of sorcery. He reconstructs the truth from the charcoal stove, the flue, and the order in which the victims died. Others believe a celestial stone can reverse life and death, but he discovers that it is altering the laws of physics nearby.
The more he understands, though, the more trouble he gets into.
He has barely proved that he isn't the murderer when he discovers the original body's secret laboratory. He has barely figured out the strange charcoal when he learns that hundreds of households have already been caught up in it.
Worse still, the fragment engraved with an unfamiliar serial number is exactly like a piece of experimental equipment from his own world.
The only thing Lu Heng wants is to find a way home.
But this world doesn't seem to want to let him leave.
