Lin Wan, a modern medical student, traveled to the prosperous Tang Dynasty because of her gilt-bronze bell. She used the combination of traditional Chinese and Western medicine to solve dystocia, treat septicemia, and save soldiers on the frontier. She transformed from a handyman in the market to a "medical woman who helps the world." By chance, they meet Xiao Ce, a seriously wounded general who is cold on the outside and hot on the inside. The two redeem each other amidst court disputes and border wars, and go from suspicion to love. When modern medical skills collided with the turmoil of the prosperous Tang Dynasty, she chose the frontier instead of glory. She joined hands with him to defend the land, practice medicine to help the world, and wrote a legend of staying together across time and space in the afterglow of the prosperous age.
