When Chen Guan, a young Feng Shui master, was sorting out his grandfather's belongings, he discovered a bronze compass engraved with the secret hexagram "Gui Zang" and half a fragment of a book recording the mystery of "Nine Cauldrons to Suppress the Dragon". Soon, a mysterious employer hired him with a large sum of money to solve the Feng Shui mystery of a Warring States tomb. He was accompanied by Ling Qinglan, a beautiful archaeologist who believed in the supremacy of science.
Under the ancient tomb, what they saw was not a coffin, but a huge mercury labyrinth that moved according to the stars. With the guidance of the compass and the fragments, Chen Guan applied metaphysical theory to practice for the first time, and made a thrilling breakthrough, but what he got was a jade slip suspected of being "Lianshan". Only then did they realize that they had been involved in a huge whirlpool that spanned three thousand years.
From the nameless altar at the bottom of the Yellow River, to the Western Zhou Observatory on the top of the snow-capped mountains, from the land of Youdu recorded in the "Shan Hai Jing", to the unknown metaphysical structure under the Forbidden City... Chen Guan and Ling Qinglan used metaphysical deductions, and confirmed it with historical data, gradually approaching the truth: Jiuding is not a symbol, but a huge "instrument" that covers China, and its core secrets are hidden in the lost Yiyi of "Lianshan" and "Gui Zang". And a mysterious force called the "Seven Star Society" is trying to restart this "instrument" at all costs, and its purpose is enough to subvert all existing orders.
