An alternate-history novel set three hundred years after the founding of the Dayan Dynasty. Heaven's Mandate wanes, the vassal lords grow powerful, and the emperor loses his authority. The years 312 to 320 of the Dayan era are known as the "Dayan Blank Period." Later historical records are almost entirely silent about these eight years. No one knows what happened.
Transmigration premise: In 2024, historian Gu Shenyan touches a mysterious turtle shell and transmigrates to the year 312 of the Dayan era. He never considers going back. Being able to witness firsthand the era he has spent his whole life studying is the greatest gift fate could give him. He wants to do only one thing: write a true historical record for this age.
The central mystery: Why are these eight years missing from the history books? Who erased this part of history? Can Gu Shenyan's records cross a thousand years and be discovered by future generations?
