I Became the Wicked Mother-in-Law of a Farming Family

I woke up to find that not only had I aged a few years, but I had also acquired several “unfilial sons.” What am I supposed to do? My eldest son is hardworking and capable, but he's a bit of a blockhead. My second son is obedient and honest, but he's a pushover. My third son is a little “stupid,” yet always thinks he's clever. My fourth and fifth sons barely make their presence felt, like “invisible men.” My seventh son damaged his brain and is a “fool.” The only girl, my eighth, was raised to be so “delicate.” All she dreams of is becoming a maid in a wealthy household, so she can be a rich young master's concubine and live the good life... As for me, their “mother,” I exploit the whole family to raise my daughter. I'm the worst of the lot.
