I Reincarnated as a Rich Heiress Returning from Abroad, and I Just Want to Lie Flat and Enjoy My Retirement

[Military marriage in the 1950s + top research scientist + lie-flat lifestyle + both leads' first love + sweet romance + face-slapping] In the 22nd century, forty-year-old Tang Yunshu finally retired early. She planned to drink tea, grow flowers, and lie flat in retirement, but the new Ox-Head and Horse-Face messengers at the underworld sent her soul to the wrong place. To make it up to her, they tossed her into a parallel timeline in 1956. And she even got a "lost her virginity" starter pack from the start?! Tang Yunshu: Fine, I'll make the best of it. So she was actually the daughter of a research scientist who had just returned to China, as well as a young heiress of the red-capitalist Tang family? This was the perfect setup for a blissful retirement! Who knew that before she could even set up her lounge chair, trouble would come knocking one after another. That outrageously handsome, battle-hardened regimental commander actually came to ask for her hand in marriage? And after she joined the army, she discovered he had a "fiancee"? Tang Yunshu frowned. "How can this be? It'll seriously ruin the quality of my retirement! Wait, this fiancee seems a little off. Let me take a closer look." Even more absurdly, the little "trinkets" she casually tinkered with out of boredom caught the military's attention, and they even wanted to reward her? Her retirement income was taken care of. What a sweet deal! But who could have guessed that these "retirement trinkets" would attract enemy agents? Tang Yunshu: "I just wanted to lie flat in peace. How did I end up becoming a national treasure?" Gu Xuzheng pulled her behind him, his gaze icy, though his voice was gentle beyond belief. "Don't worry, honey. As long as I'm here, no one will disturb you while you lie flat." Amid the turmoil of a chaotic era, all she wanted was a peaceful life. Yet with her advanced knowledge, she protected her family, fought enemy agents, and unintentionally helped advance the nation.
