[A Chinese Ghost Story + Three Kingdoms] Medicine Can't Save the People of the Three Kingdoms

This is my first time writing a story, so please give me some pointers~

During a trip to the South China Sea, the young hero Bingxin, Hua Zhonglou, is forced to transmigrate due to a mistake by the Jialan God. He becomes Xie Yan, a gravely ill three-year-old child near death at the end of the Eastern Han dynasty. The beacon fires rise, the road ahead is hard, and the young hero, who hates war with all his heart, decides to return to his old profession and travel the land to hone his medical skills. But why do his old classmates keep trying to trick him into entering politics? And why does staying around them always make him feel blinded by their dazzling brilliance?

This is really just a story about a young hero from the Great Wilderness searching for a way home while watching all the romantic entanglements of the Three Kingdoms unfold. Female transmigrates into a male body, so proceed with caution if that's not your thing!!! The young hero himself has no romantic pairing in the Three Kingdoms; he just watches from the sidelines. The couples I'm pretty sure I'll write are Cao Cao and Xun Yu, and Zhang Xiu and Jia Xu. Wu and Shu will feature less, so we'll see when we get there.
