Transmigrated into the Body of a Powerful Figure's Vicious Ex-Wife, and Pregnant with Triplets

I transmigrated, and into the body of a universally hated, vicious ex-wife in a period novel! The first thing I saw when I opened my eyes was my husband, Zhou Yan, a high-ranking military officer, throwing divorce papers at me: "Sign!" I touched my stomach and blurted out, "I'm pregnant!" He tore up the divorce papers on the spot. Later—"Reporting, sir, your wife made those troublemakers in the performing arts troupe cry!" Zhou Yan: "Give her some herbal tea to soothe her throat." "Commander, your wife sent homemade chili sauce to the whole troupe!" Zhou Yan: "Order two hundred more glass jars." Until the day of my prenatal checkup—Doctor: "Congratulations, it's triplets!" Me: ??? The original novel clearly said she was only pregnant with one child!
