The modern Xue Qingyin traveled through time and became the tragic heroine in the ancient novel "The Only Favorite Princess". In order to change her destiny, she approached the ruthless King Xuan He Junting, hoping to use his power to save her life. The male protagonist of the original book and vested interest groups constantly hindered her from changing her destiny due to competition for interests. He Junting faces the dilemma of revenge and protecting Xue Qingyin. When Xue Qingyin first arrived in ancient times, her status was awkward and her abilities were yet to be developed. She struggled to develop under the complex palace environment and the discipline of the feudal system. Her plan against He Junting caused misunderstanding. If He Junting's background was exposed too early, he would be killed, and all forces in the palace were full of hostility towards them. However, the two gradually developed a true love as they got along. He Junting finally took revenge and succeeded in ascending to the throne of God, while Xue Qingyin became the queen, rewriting the ending of the double death.
