After Transmigrating as a Wicked Mother-in-Law, I Take the Whole Family to the Imperial Exams

Cheng Qingning transmigrates into a doted-on heroine novel, becoming the spiteful grandmother who constantly makes trouble for the lucky heroine. She has four sons and one daughter, and aside from the heroine's family, every one of them is a complete oddball. Since she's stuck here, she might as well see it through! The villagers are stunned. The old lady is still as sharp-tongued and formidable as ever, but she leads the whole family to prosperity. Her daughter becomes a noble consort, her son becomes a prime minister, and the family becomes wealthy merchants... Not one of her children or grandchildren turns out useless. In short, the Xiao family ancestors must be smiling down on them! Cheng Qingning thinks she's got the story of a widow raising a child, but one day her supposedly dead husband returns, and his identity is rather special!
