I Traveled Through Time with My RV, the General Pampered Me Gently

Bai Hanyu, a female surgeon from a family of traditional Chinese medicine, was inexplicably transported to an era that did not exist in history. There were four countries here: Nanlin Kingdom, Dongshi Kingdom, Beihan Kingdom, and Xisha Kingdom. The Southern Forest Kingdom is rich in resources, has developed trade, and has a strict hierarchical system. Dongshiguo Mine is rich in resources and is the largest recipient of human trafficking. The Northern Han Kingdom is lacking in resources and was built in a barbaric land. Women are scarce and men are rough and barbaric. The Xisha Kingdom was born in the vast desert and lives in an oasis. Most of the people in the Xisha Kingdom know magic and have strange cavalry. The capital of the country changes with the oasis. Bai Hanyu traveled around the four countries in an off-road RV, but he was followed by many followers, especially the general of the Nanlin Kingdom. He was really annoying, and he promised to save his life. (The male and female protagonists have been in love for a long time. They loved each other without knowing it in the early stage, but from benefit and use to cherishing each other in the later stage, they attract and appreciate each other.) Although the heroine was born in a family of traditional Chinese medicine, she does not know much about traditional Chinese medicine. After becoming a surgeon, she relied entirely on technology. Later, she slowly learned traditional Chinese medicine in ancient times and left high technology to treat patients. The male protagonist was originally a general who protected the country. Because of the king's jealousy and suspicion, he embarked on the road of overthrowing the regime, and eventually became a usurper and the leader of the Nanlin Kingdom. (There is a second male lead! Group portrait! Not invincible! Space is not invincible either!)
