Sacrificing Mortality for Mr. Right

[Warning: Mature content] I graduated, but not just with the diploma. I was invited to live in an otherworldly realm by my professor, who surprisingly is the Dong Clan's Emperor. Yes! I agreed, to find my supernatural man out of greed. My name is Celestina Marquez, who later became Gu Muyan, the Dong Clan's princess. I never missed an opportunity, but I made a mistake by falling for our enemy. I was betrayed blindly, and used my weaknesses to defeat us easily. A strong woman like me, will never let anyone fool me. I will mark in my mind that there is no destiny of being in a relationship with my enemy. I was offered to be the princess, then became the ruler of the Dong Clan. And as a powerful ruler, I am destined to destroy the Demon Clan. As a powerful ruler, I will make them all shed their own blood for the better. POWER to POWER! SWORD to SWORD! I will protect my clan even if my life is like a double-edged sword. I don't mind their arrows; I can defend myself with my powers. I will use my power correctly to make them all disappear permanently.
