Xu Jiao, a modern surgeon, transformed into an orphan from a poor family and was forced to lead the whole village to escape famine. She picked up the scalpel, saved people's lives from the plague, and became a famous doctor. Just as the home was being rebuilt, enemies from the previous life came with their cavalry. To protect the people behind her, what she holds tightly is no longer a scalpel, but a blood-stained spear. When a famous doctor turns into a god of war, she wants to save not only human lives, but also the broken mountains and rivers.
