The Regent's Princess Consort Says Kneel, and Every Child in the Capital's Knees Shatter

[Transmigration + System + Strong Female Lead + Reforming a Brat + Political Intrigue] Jiang Yunchu, a modern battlefield medic, was either on the battlefield or on her way there. Jiang Yunchu, the neglected eldest daughter of a general’s household, was a dull, taciturn girl. A strip of white silk later, the military doctor became the young lady, and her fate changed. On her wedding day, she kicked over the brazier to scare her stepson, then splashed ink all over the door. Her stepson puffed up like an angry little pufferfish, while the Dowager Consort entrusted her with a child and went to the imperial mausoleum. She’d hoped to live an idle life, but this brat was simply asking for a good scolding. “Heh. Ning Hanmo, how can you bring yourself to pull such a childish trick? I’m seriously questioning your intelligence!” “Ning Hanmo, making a spectacle of yourself like this is really embarrassing.” “Ning Hanmo, are you only three years old? Even a little kid wouldn’t act like this!” “Ning Hanmo…” Over time, Jiang Yunchu found that amusing herself by teasing her stepdaughter when she had nothing to do, and messing with her stepson when she was bored, made for such a lovely life that she wouldn’t trade it for anything, not even immortality. Wait, who was this handsome man? He said he was the regent? That couldn’t be right. Wasn’t she a widow? What had gone wrong? This novel has a couple, but the male lead appears late.
