Qiankun

A fifty-year-old woman, Ji Fei, entered the fifteenth year of Wanli four hundred years ago in the Qiankun Consciousness Experiment. She gradually knows where civilization will go in the 2400s four hundred years later, but no one believes her. The only thing she did right was to fall in love with the 19-year-old youth who had not yet become Feng Menglong, and to write a novel with him that would allow the future to recognize her.
