I Transmigrated into a Book Set in the 1970S and Switched Marriages, Then Had Twins with the Powerful Heir

【Transmigrate into a Book + Join the Army + Supremely Satisfying and Badass + Swapped Marriages + Military Compound + Space + Sweet Romance + Barren Husband + Multiple Pregnancies】 Song Anning, a top medical-school student, unexpectedly transmigrates into a ridiculously melodramatic period novel. She becomes its heroine, who seems to have everything but is actually the very picture of spinelessness, misery, and saintly self-sacrifice. But Song Anning isn’t some tragic, pitiful flower. She’s a dazzling, seductive, wild red rose. Her reborn sister-in-law wants to defy fate and switch husbands? Fine, fine, she can have her way. Let the scumbag and the wicked woman be shackled together for good. Her madwoman of a mother gets bullied every day? Young or old, it doesn’t matter. Song Anning charges in and gives them all a good thrashing! Poor? She has a portable space, a magical spring, experience from her past life, and more money than she can spend. She thought that, as a lifelong singleton, she’d focus on building a career after transmigrating into a book. Who could have guessed her marriage would be switched? Her husband has an eight-pack and long legs, is devastatingly handsome with a bright future ahead, and treats her like his most precious treasure. A man this good is obviously one she has to hold on to. She hears her rough-and-tumble husband has a hidden condition and can’t have children. But just one month after the wedding, she’s proudly battling morning sickness!
