What?? Lan Wangji's boring husband can harvest energy from demons? They are from different worlds indeed—if any human had learned this power in Luo Binghe's world, it would have caused a war between the realms. And a massive headache for the Emperor.

Luo Binghe did not think he had anything to fear from either Lan Wangji or Wei Wuxian, who he doesn't recall having much of a spiritual aura at all—although perhaps that's because he gets his power from corpses and demons. And Lan Wangji is keeping this man in submission using his body?? There are stranger happenings in this mansion than Luo Binghe knew. He's still not afraid of either of them, of course, but he is shaken. As one of the only demons here, and an exceptionally powerful one too, he would be a natural target.

"I'll heed the warning," he says, "and your assistance will not be forgotten."
