In the eighth year of Xining, Shen Yan, a minor official at Taichang Temple, woke up and found that there was an extra notebook in his memory that did not belong to this era.
The notes recorded things that had not happened yet: the Gyeongju Civil War, Yuanfeng's restructuring, the old and new party struggles, and a handwriting he recognized - his own.
He tried to do something. But he soon discovered that people who know history are not necessarily those who can change history.
A notebook is both a witness of the times and a participant in the general trend, and ultimately becomes a recorder.
