The Capitalist Heiress Has a Pocket Dimension and Joins the Army, Waiting to Become a Martyr's Widow

[Rich heiress impostor-and-real daughter + clearing out the family fortune + spatial livestream comments + military marriage in a bygone era] If you accidentally transmigrated into the real daughter, a cannon-fodder foil from a capitalist family in the 1960s, what would you do? Fang Qinyao, armed with a million supplies and a stream of viewer comments, had one thing to say: To hell with being a cannon-fodder foil. Whoever wants the role can have it! The fake-daughter heroine wants to steal her arranged fiancé? Her fiancé says, “I only love Lan’er. I don’t feel anything for you.” Fang Qinyao replies, “A scumbag and a shameless woman make the perfect couple. I hope you stay together for all eternity!” “Here’s 300 yuan for your betrothal. Dress yourself up nice for me. I’ll come get you in three days.” A local bully wants to forcibly make her his bride? Oh no! Fang Qinyao panics! The comments spoil the plot: “Isn’t that Gu guy next door the short-lived martyr?” “Yeah, the one who doesn’t even make it past fifty thousand words.” A short-lived martyr? Wasn’t he practically made for her? As a capitalist heiress, even if she escapes being abducted as a bride by a bully, she can’t escape persecution, being sent to the countryside, and labor reform. If she marries Gu Qichen, then when he becomes a martyr, she’ll be the widow of a martyr. With that status, who would dare treat her badly? She’d be married without having to serve a husband or raise children, free of worries and able to enjoy a million supplies all by herself. What could be more idyllic? Fang Qinyao happily clicked away at her plans and speedily married the rugged army officer. But one year passed, then two… Oh, dear heavens! Can someone please tell her what went wrong? Why was this supposedly short-lived man still full of energy every day, and why was he so vigorous every night, always trying to climb into her bed and have children with her?
