It is recorded in the novel that at the end of the Qin Dynasty, this sacred object drifted to the south of Yunnan. It was because of this dust that he left the country and prepared to find a place to cultivate immortals in the mountains. Liu Che Mausoleum of Emperor Wu of the Han Dynasty is just a fake shadow bead, and the real dust bead was put into his mouth as a funerary object after his death.

After watching the drama "Yunnan Worm Valley", I think this drama is still very exciting. Many plots in it are highly restored with the novel. Although some plots were deleted, it did not affect the overall progress. After Hu Bayi took Wang Pangzi and Yang Ping to Yunnan, they met many things.
After they entered the wormhole, they met many strange things, including human pupae, which contained many bugs and piranhas. The situation is very critical. They haven't met Xuan, and Wang Mo already knows so many Wechat messages. If you really see Wang Xian's tomb, I don't know what problems you will encounter. This dust bead is not easy to find.
