Shen Jingwan is a concubine who no one cares about in the Shen family. She was pushed by her aunt to marry Xiao Wan, the prince of Zhenbei Hou, the rumored "Jade-faced Yama" who is a murderer without blinking an eye. She thought it was a sheep entering the tiger's mouth, but with her medical skills, she stood firm despite the open and covert attacks of the Hou Mansion, and even saved Xiao Wan in distress in the fire.
From being suspicious of each other to working together to break the situation, the two team up to uncover the second son who set the fire, bring down the traitors in the palace, and gradually uncover the mystery of the life experience of the descendants of the royal family in the Western Regions. From marrying an orphan girl to a lady protecting the country, from a cold-faced prince to a protector of the Western Regions, they supported each other in the whirlpool of the court and the rivers and lakes. Finally, the years were peaceful and they traveled thousands of miles together.
