"It's cultivation from a demonic source," Luo Binghe says with some relief—Magnus seems a little warmer toward him than before. "Human spiritual qi and demonic qi are different types of energy. Demonic qi is stronger, but more destructive, harder to control. And most magical artifacts work better with one kind or another. I'm half-demon and half-human"—he remembers that he hasn't explained this before, since he was pretending to be a god—"so I can use both kinds." It's a bit meaningless to demonstrate in a dream, since Luo Binghe can do whatever he wants anyway, but he holds out his palm and ignites a flame in it. The flame fades from the warm yellow-red of spiritual qi to the flickering black of demonic qi and back again. He's not actually switching between his human and demon qi pathways, since his physical body is not present—he's just using dream cultivation. But this is what it would look like if he were.
