I believe I disregarded the novel but now i found a comic that I'm reading and it revolves around a girl name Liu Duo who was sick in her previous life but has transmigrated since death into a historical setting.. She lives with a family of brothers (?) And I think it was that they shared wives because there was a lack of females/a wife brought prestige ? Anyhow they're poor too. I know the author is 念已伤 from qidian (the comic's novel), the story is 田园蜜宠:农家小娘子火辣辣 ? Has it not been translated on novelupdates?
Sounds like my kind of novel. ^.^ Only I'm not sure it's being translated. I goggled the title and just got Chinese in return.
I have I have two novels in mind. I do remember 1 did become a manga. I’ll try to find it if I can remember or if it’s in my bookmarked novels.
