Xiao Ran transmigrated to a fantasy world. As a dungeon guard in the Celestial Dungeon, with a special floor called the Purgatory meant for powerful demons and martial arts experts, he faced a huge challenge from the start. The Eldest Princess acquired a forbidden martial arts technique and was banished to the Purgatory. However, no one was powerful enough to restrain her. All the dungeon guards were defeated. Xiao Ran stepped up and declared, “Your Highness, it’s better for you to behave yourself on my territory” and effortlessly subdued the Eldest Princess.

He progressed from imprisoning the Eldest Princess to delivering the Great Xia Kingdom from the evil clutches of various demons and evil martial arts experts.

Xiao Ran was the mastermind behind the scenes.

My memories of my past life returned when I hit my head on a rock. I am Katarina Claes, the eight-year-old daughter of a Duke. While I was struggling with a high fever, it was decided that I would become a prince’s fiancée. I have now realized that this is the world of an otome game I played in my previous life.

I also realized that I had become the villainous noble girl who got in the way of the protagonist and her capture target… if the protagonist got a good ending, I would be exiled from the country with only the clothes on my back, while in the bad ending, I would be killed by the capture target… where’s my good ending!? Do I only get bad endings!?

I want to overcome all the destruction flags somehow and reach old age!

Five hundred years later, a superhuman talent cultivated by the state perished during a mission, and his soul transmigrated, taking possession of the body of a young master from a prominent family who suffered from an anxiety disorder. From that moment on, his extraordinary life began, spanning across various fields such as business and medicine. Wherever he set foot, others could only look up to him.
