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. Because of this, her meridians were blocked, hindering her cultivation, which eventually led to her being known as trash. After being beaten to death, Mu Ru Yue, who had originally been a successor to a medicinal aristocratic family in Hua Xia, reincarnated into her new body. They want to seal my path? I will train to reach the peak of the realms! They give me a foolish prince as my husband? I can make do with him. It would be easier for me to deal with him, rather than with other candidates who would be thrown at me in the future. I shall strive to become powerful enough that nobody will be able to mock or kill me.

When I opened my eyes, I was inside a novel. [The Birth of a Hero]. [The Birth of a Hero] was a novel focused on the adventures of the main character, Choi Han, a high school boy who was transported to a different dimension from Earth, along with the birth of the numerous heroes of the continent. I became a part of that novel as the trash of the Count’s family, the family that oversaw the territory where the first village that Choi Han visits is located. The problem is that Choi Han becomes twisted after that village, and everyone in it, are destroyed by assassins. The bigger problem is the fact that this stupid trash who I’ve become doesn’t know about what happened in the village and messes with Choi Han, only to get beaten to a pulp. “…This is going to be a problem.” I feel like something serious has happened to me. But it was worth trying to make this my new life.
