I recommend the two novels, Nirvana Phoenix and Reborn Concubine's Daughter Becomes a Phoenix, to you. The female protagonists of these two novels both had the identity of a phoenix, and there was an obvious phoenix mark on their bodies. In "Nirvana Phoenix," the female protagonist had to fight hard to protect herself and the people she loved. She had to go from an ugly duckling to a phoenix that ruled the world. In "Rebirth of a concubine's daughter as a phoenix," the female protagonist had to obtain the dragon energy of the human world in order to become a phoenix again. I hope you like my recommendation.
