Mu Ru Yue, was a successor to her medicinal aristocratic family in Hua Xia. After being murdered by her enemy, she reincarnated in the body of a recently deceased good-for-nothing Miss in the Mu Family of the Martial God Continent, who had been beaten to death. In the throne room, she smilingly received a marriage notice to have a change in marriage to wed the infamous Ghost King from the Kingdom of Zi Yue. It was well-known that the Ghost King was stupid and foolish, with a ghost-like appearance. But who knew that he was actually the most two-faced person? Everyone laughed, thinking that a good-for-nothing was well-matched to a fool, but not in their wildest dreams did they even consider that she was actually a peerless genius in the making. When Mu Ru Yue looked at the man, who had a handsome God-like look, she said, gnashing her teeth, “Ye Wu Chen, you lied to me. How are you a fool at all?” The Ghost King chuckled as he affectionately embraced her. “By your side, I’m willing to be a fool that you can freely order around.” Miki’s summary The previous owner of Mu Ru Yue’s body had been poisoned.

I shall strive to become powerful enough that nobody will be able to mock or kill me.
