What happens when a brilliant military doctor from modern-day China crashes into history-literally? At 25, Lin Yue had it all: a sharp mind, a thriving medical business, and a steely resolve honed on battlefield frontlines. But fate takes a strange turn when a tragic plane crash sends her soul spiraling back in time... waking up as a 16-year-old merchant's daughter in the heart of the Han Dynasty. Armed with knowledge far beyond her years, and a mysterious golden space filled with self-replenishing medical supplies, Yue must navigate the perilous world of ancient politics, rival merchants, and skeptical scholars, all while hiding her secrets. Unbeknownst to her, her path is fated to cross with the empire's most feared and misunderstood man-the cold and unyielding Sixth Prince, a war hero cloaked in icy silence.
