In the second year of Kaiyuan, Yazhou in Lingnan.
The exiled "Queen of Sinful Ministers" Zhou Yin woke up at the seaside with only half a volume of "The Classic of Mountains and Seas" left in his arms.
In order to survive, he pretended to be a descendant of the Langyayan family and traveled around the border in the name of a "natural gentleman".
The governor probed: "I heard that Yan is proficient in the "Shui Jing", what are the water veins in Yazhou like?"
Zhou Yin replied: "This water comes out of Aoshan Mountain, flows eastwards for thirty miles and lies underground. It is the 'Dan'er Undercurrent' recorded in the "Hainei Dongjing". Its taste is salty and astringent. It cannot be used for irrigation in fields, but it can be used to boil salt."
Everyone in the house was shocked.
Little did he know that what he said casually coincided with Chang'an Si Tiantai's secret performance——
There is "dragon spirit" in Lingnan, which originates from Yazhou.
And the female historian from Chang'an had been standing outside his door for three days.
She held a faded marriage book and asked softly:
""The Classic of Mountains and Seas: The Great Wilderness South" says: 'Xihe, the wife of Emperor Jun, was born on the tenth day'."
"Since you know the mountains and seas well, you know——"
"Who am I?"
