[Recommendation/Drama] Mistake at a 70s blind date, hit the jackpot after marrying the right person!

This is a satisfying novel set in an era that combines rebirth and revenge, technological advancement, and a marriage that turns into love after tying the knot. Tragedy in the previous life: The female lead, Sang Luo, thought she married her childhood sweetheart. They lived separately for fifty years without children, and she never complained. Only upon retirement did she shockingly discover that their marriage certificate was fake, and her husband had another wife and a large family. Enraged, Sang Luo decisively reported the scumbag, only to be brutally murdered by him. Rebirth and Counterattack: She unexpectedly reincarnated back to the day the scumbag proposed. She resolutely decided to abandon the scumbag and turn to a blind date with a military officer. An accidental twist: She went to the wrong table at the blind date and married Commander Zhang, who appeared stern and impartial on the outside but was clingy and deeply affectionate in private. They began a sweet life of love after marriage. Contributing to the nation with technology: After rebirth, Sang Luo utilized her professional knowledge from her previous life to engage in scientific research in the 1970s, leading the country to global leadership in color televisions, new energy vehicles, and aerospace, thoroughly defeating the villains. There weren't many angsty scenes or pointless arguments, which I really liked. Plus, the male and female leads are both handsome, so it's easy on the eyes 🥰 I removed the spiritual spring space mentioned in the synopsis because it wasn't there; the female lead is powerful enough on her own. Female Lead: Mi Qi Male Lead: Wu Zhu Xi
