Sent To Die In Countryside, Marry Deathbed Soldier, But With Apocalypse Skills We'll Build Empire

After surviving the apocalypse and waking up in 1970s China, she discovers her mother is trying to steal her nursing job, marry her off like discounted furniture, and protect a creepy stepbrother who keeps sneaking to her window at night. Most people file a complaint. She files a complaint, exposes the creep with a secret recording, escapes illegal detention, robs a corrupt official blind, destroys his political career before breakfast, and comes back in time to file ANOTHER complaint. Her enemies thought they were bullying a quiet schoolgirl. They accidentally declared war on an apocalypse veteran with a pocket dimension, unlimited receipts, and a PhD in ruining corrupt people's lives.
