There's another version of human swine, one that I read about in My Father in Law is Lu Bu. Basically same principle, but instead of putting them in a pigsty you put them in a jar filled with excrement and piss.
This manhua still greatly amuses me, although it can be confusing watching the MC genderbend. At this rate, the MC will BE a harem, unto himself (if he still identifies as a he?).
