Tomb Robbing Mystery

Nearly a hundred years ago, an emerald human figurine in the mountains mysteriously took the lives of thousands of young men and Beiyang soldiers, leaving only one person alive. Nearly a hundred years later, this man's grandson He Yuan, as a veteran tomb robber, discovered a tomb within a tomb from the Warring States period during an ordinary trip, which led to a series of secrets: Emperor Wu of the Han Dynasty, Lord Xinling, Marquis of Wei Wen, Jiang Ziya... These names that originally only existed in history and legends were vaguely related to him. The most important thing is that people keep telling He Yuan that he is that person. Who is that person, and who am I? There seems to be a force in the dark that has been pushing He Yuan to the final answer, and what is waiting for him there?
