Gokuaku Jotei no Koukyuu

In the great nation of Sai, which reigns over the continent, there was a peerless beauty. Her name was Li Honglan.

*"I'll cut off that man's head."*

She was feared both at home and abroad as a ruthless empress. However, at the urging of a senior vassal, she has decided to take a husband. His partner is Wang Longyuan, the fifth prince of the vassal state of Shu.

*"Let me tell you, there aren't many men who could become my husband."*
*"I'll never bow down to you of my own free will."*

What seemed like a beautiful and well-matched wedding, but their back-and-forth exchanges have already created a turbulent atmosphere. What is Longyuan's secret? What is hidden in the harem? What will become of Honglan's fate?
