When Bai Wei saw the blood that Lair spit out, he belatedly realized that he had nearly forgotten the basic setting of sacrificing life force.
Though thinking about it, it's not quite his fault, considering after Ulu, his hosts have been remarkably resilient. Gerard's steel-like body far exceeds ordinary people, Hewinia's music scores body is especially resistant, and Ade never even became his host. So when using Lair, a true mortal, he didn't immediately think of the side effects associated with his powers.
And it's the major side effect of "Domination." With just a few words, Lair's lifespan was halved. If he'd said a few more, Bai Wei might already consider searching for the next host.
"Vi, Visas lord." Seeing Bai Wei remain silent for a long while, Lair became more panicked, "W-What's happening to me? Please, don't scare me."
"Ah, don't worry." Bai Wei said leisurely, "It's just a minor side effect, that's all."
