Wen Ning is slightly emboldened by realizing he might have slightly more insight, though that's such a surprise it's also disorienting. And. Doesn't bode well, given his insight is pretty bare. "It's not... Terribly uncommon back home? It's sort of down to what you can, well, afford to support in a household." He's cautious, since the arrangement he's referencing is pretty contingent on there being a much stronger power differential than he hopes there is here. Cultivation clans are generally a bit better for women than the gentry in general, since talent doesn't always respect chauvinism, and a child's chances for turning out impressive are better if both parents are gifted. But it's still not equitable.

It is, however, something. "The only person I knew well with a big harem, well, it wasn't a happy one, but he was..." Wen Ning may have poisoned the cousin in question, but he still can't bring himself to be rude. "Not a harmonious person himself. I don't know why it couldn't work."
