I recommend 'Rebirth in the Early Years of Kangxi' to you. This ancient romance novel described that the female protagonist's aunt was Empress Xiaokangzhang of Emperor Shunzhi. Later, she married Emperor Kangxi, and the female protagonist was reborn as the third empress. She had liked Yinzhen since the modern era. After returning to the past, she tried her best to pursue him and had feelings for him. In the end, she gave birth to Hongli. I hope you like my recommendation.😗
