After Switching Bodies with the Young God of War General

Lu Yun was born into a family of scholars. She was a gifted and learned woman of her age, praised for her talent even by the emperor. Yet her fate was cruel. After marrying the wrong man, she was sent back to her family. On the way, she was captured by northern horsemen and stranded in a foreign land for years. She spent half her life drifting alone, and while still young, became bedridden with illness and eventually died. Reborn, she returned to the beginning of the turning point that had changed her fate in her previous life. Just as Lu Yun tried desperately to avoid it all, only to find herself facing it again, she resolved to meet her death calmly rather than repeat the mistakes of her past life. Then she suddenly realized... She had awakened in the body of a young man she knew. Gu Chengfeng. The young genius of royal descent who subdued foreign tribes, slew enemy forces, safeguarded the realm, and earned outstanding military honors, becoming known as the God of War. The only thing people regretted about him was that his glorious life ended when he was just twenty-four. He was also her... benefactor. Gu Chengfeng had merely taken a nap. When he woke, he found himself surrounded by a group of foreigners glaring at him menacingly. What the hell? They dared to rob him on the road? After using a carriage panel to beat the bandits into submission, the still-unsatisfied young General Gu suddenly realized... He seemed to have turned into a girl? * Two strange events recently took place in Chang'an: First, the learned, gentle, and universally admired Miss Lu single-handedly defeated every bandit along the roads to the southeast, beating them until they knelt and called her their father, then came to submit and worship her. Second, the unruly young General Gu, who had been rebellious since childhood and loved riding through the streets, obediently went to study at the Imperial Academy. He then debated all the scholars in class and impressed every student and teacher with his extraordinary knowledge, leaving them eager to seek his guidance. Everyone: ...??? Hold on, are these absurd events really not just rumors?!!! The two people involved, constantly met with cries of "Good heavens, how strange!": "Hmm... why not?" The two of them are about to get married, and they're growing more and more like a married couple. It makes perfect sense, doesn't it? P.S. The setting is fictional, though some characters are loosely based on historical figures. Everything is designed to serve the romance. I'm doing my best to write a sweet little love story~ Theme: Change the regrets of the past
