General Shen has a pair of twins. When his son dies, he makes his daughter take his place and go to war.
She goes out to catch a rabbit and comes back a different person? To escape an arranged marriage, she chooses to keep pretending to be her younger brother. But she never expected war to break out so soon. Not wanting to die far from home, she hurriedly searches for a way back. She eats a pile of poisons, but it backfires in the best possible way: her body becomes immune to every toxin, and her abilities double.
Since none of her attempts can get her home, she decides to stay, focus on making money and building a career, and win over powerful people to find herself a patron.
She was planning to use a secret imperial edict to escape the marriage arranged by the current empress, who was trying to build up her faction. But then the Prince of Yi, rumored to have died in the wilderness, returns to the palace alive, and the edict orders her to marry him.
Wait, why does this man look so familiar?
Is this the man she has longed for day and night?
When she wanted to marry him, he refused. Now he wants to marry her. Sorry, she's off to study medicine all over the place.
