Transported into a Period Novel, the Cannon Fodder Turns Her Life Around!

【Fussy little beauty x rugged military big shot】 Yu Tao had a heart attack and transmigrated into a book, becoming a beautiful cannon-fodder character! The original Yu Tao had fair skin and striking looks, loving parents, and a younger brother who always had her back. She was spoiled rotten and did whatever she pleased. But who knew the heroine had been reborn? She deliberately set Yu Tao up, getting her dumped by her fiancé's family. Then the heroine took her place and began her own happy life. Poor Yu Tao lost not only her engagement, but also suffered everyone pointing fingers at her. Unable to bear it, she jumped into a river and died just like that. And now Yu Tao had transmigrated into her place. The good news: her supermarket came with her, so she'd never have to worry about food or drink. The bad news: she had to marry a man seven or eight years older than her and become stepmother to three children!! Yu Tao: “...What did I do to deserve this!” Still, her bargain husband was seriously handsome, and Yu Tao was a little tempted. What? He hands over his entire monthly salary! And he often goes away on missions for eight or ten days at a time! As for following him to his posting, Yu Tao was all in. She had to make this marriage happen. So she happily married him, spending her days eating and drinking to her heart's content and getting completely absorbed in cuddling the little ones.
