Su Xuruo could have lived a prosperous life in this ancient time more than 400 years ago, but he was born into a family of eunuchs, married into a family of military generals, and got involved in party strife. He thought that would be the end of it. Who would have thought that returning to modern times would meet Shen An again.
Shen An never imagined that Su Xuruo would die in the year when they loved each other most, leaving only one letter and one dead. Later, he searched the world and finally found immortality, and met her again through the long river of time.
