Tang Dynasty Backup Plan

Su Yuan, a doctoral student in archeology, unearthed a Tang Dynasty gold slip engraved with a mysterious "QR code" pattern at the ruins of Daming Palace. That night, his soul traveled through the twenty-fourth year of Kaiyuan—nineteen years before the Anshi Rebellion broke out. He discovered that his possessed identity was actually the last descendant of a secret organization called "Tiangong Division". The code on the golden slips is a "relay plan" that spans a hundred years and was left behind by the predecessors who predicted the crisis of the Tang Dynasty. Improve a piece of paper, promote a plow, help a person.
