Transmigrated as the Commander’s Vicious Ex-Wife and Brought my Two Kids to Join the Army

Xi Youyou transmigrated into a period novel, becoming the wicked female supporting character. To avoid being sent to the countryside, the original owner schemed against the female protagonist's brother, forcing him to marry her, causing him to be suspected of poor character by the military and miss out on a promotion opportunity. Afterwards, she continued to cause trouble, leading to his mother's death. Finally, after divorcing and losing custody of her children, left alone, she falsely accused her ex-husband of having forced her years ago, causing him to be suspended. However, the military investigated and found the truth: she had drugged him herself. Consequently, she was arrested and imprisoned, ultimately dying tragically in jail.

To avoid her tragic end in the book, Xi Youyou decided to behave well. While the female protagonist (her sister-in-law) was still missing and hadn't yet returned to her birth family, she planned to build good relationships with her in-laws, with her two disliked children, and then join the army with the children. She would also build a good relationship with her sister-in-law, so she wouldn't have to worry about a tragic end!
