The Nine-Dragon Ring of the Ancient Tomb of the Wild King

The real material of this drama serves as the creative background - the tomb of King Zhutan of Luhuang in Jiulong Mountain, Shandong: Zhu Yuanzhang's tenth son died of alchemy poisoning at the age of 19. When it was unearthed in 1970, the tomb was in good condition, but the bones were blackened (caused by poison) and there were more than 1,100 burial objects, including nine crowns, dragon robes, and gold quilts. The strangest thing is that it has never been stolen. There is only a note in the tomb with the words "King Minglu" written on it.
