The two met in the most humble situation, becoming each other's mirror images and each other's armor. Starting from investigating a border mystery, they peeled off the cocoons and worked step by step. Relying on their excellent medical skills, military skills and strategies, they established a foothold in the border town and established their own power. Finally, they uncovered the truth of the unjust case, cleared up the dynasty, and became a generation of ministers and female officials who helped the country.
