She is the crown prince of the Flame Kingdom who everyone wants to kill! They commit murder and arson without committing any evil, and disemboweling people is just for entertainment. She is a well-known expert in advanced mathematics. She created the latest field of applied mathematics and successfully calculated three international laws.

When the prince becomes an emperor, who can accompany her as his queen and who is willing to marry as a concubine? But when she was reborn, it was destined that the country of Yan would be rewritten and the monarch would become prosperous... But I don't know whose young master's heart was left behind in those romantic and turbulent years. (Dear, I am working hard in the vast sea of ​​books and vast seas of books, please feel free to do so)
