The conquerer of the universe (reincarnation original)

Raven suddenly got into a car crash, fortunately she was reincarnated to a 14 year old girl, who is actually the princess of the entire universe. she also had a demon inside her body, raven in her past life was a very smart person and studied medicines, martial arts and history. she was also a lawyer and a husband she loved very much, but got betrayed very badly and she learns not to trust anyone, do you think she can survive in a world with magic and where she can't trust? do you think she can be a conquerer of the universe with so many jealous people in her way? do you think she will be able to control the creature in her body ? do you think she will fall in love again? find out more after reading this.
