In 907 AD, the Tang Empire, which was at its peak for a while, suddenly collapsed, and China entered the Great Split Period of the Five Dynasties and Ten Kingdoms. In this war-torn land, Zhao Chengding, the son of a forger from a humble background, accidentally got involved in the fight for the national jade seal. From a small arms supervisor, he gradually grew into a key figure influencing the trend of the times. He both witnessed and participated in the changes in the seventy years from the chaos of the late Tang Dynasty to the early founding of the Northern Song Dynasty - Zhu Wen usurped the Tang Dynasty, the emperor presented soil, the yellow robe was added to the body, and military power was released with a glass of wine... Against the grand background of regime changes and national integration, he used the wisdom and tenacity of a craftsman to find the possibility of "unifying the world and living in peace for the people" in the cracks of history. This is not only a history of personal struggle, but also an epic about how civilization survives, is forged and reborn in troubled times.
