In Jiuzhou Dayan, an ancient prophecy has been passed down:
“The emperor’s heart shall not die, and the mountains and rivers shall not fall.”
After the founding emperor died, his soul was sealed inside the “Candle Shadow Stone,” a divine stone that could illuminate life and death. The imperial mausoleums of later generations all used this stone as the foundation of the nation. If it were destroyed, the nation’s fortunes would decline; if someone seized it, they could exchange souls and live forever.
