High on the Qinghai-Tibet Plateau in southwestern China and northeastern India, archaeologists recently discovered a 2,246-year-old stone inscription that might record one of the most mysterious chapters in Chinese history.
The stone reads: in the 26th year of Qin Shi Huang’s reign, the emperor commanded the five Grand Master Yi to lead a group of alchemists westward to the Kunlun Mountains in search of the elixir of immortality.
