I recommend "Time Comes Easy", which is an ancient romance novel. The female protagonist was killed during the global recuperation of reiki. She transmigrated into the four Fujin and married Lord Fourth. From the Fujin to the Empress, then to the Empress Dowager and the Grand Empress Dowager, she rationally never talked about love with Lord Fourth. Finally, after successfully taking her last breath, she realized that her transmigration journey was not over. Moreover, the late emperor who had passed away many years ago had actually followed them here. The female lead, Uranala Yunxi, and the male lead, Aisin Gioro Yinzhen, would always travel through time together, living in each world until they were old. Old husband and old wife, love developed over time. I hope you like this fairy's recommendation. Muah ~😗
