Starting from a mountain village in Huizhou, Lu Yan relied on the thousand-year-old foundation of "mountain doctors to tell fortunes", treating hysteria and breaking the evil situation of ancient tombs, and gradually became famous. The mystery of the "Dragon Pillar" in Lujiazui, Shanghai, the strange sea monsters on the South China Sea islands and reefs, the secret battles at the Beijing Olympic venues... He turned ancient wisdom into the key to modern problems, step by step into the national horizon.
However, the real crisis is far greater than imagined. The Southeast Asian Yin-Yang Masters covet economic fortune, the Japanese Yin-Yang Masters attempt to pollute the scars of history, and the Western Secret Society quietly settles into the global layout. Lu Yan discovered that the "black water rushing evil" predicted by his master was not a natural disaster, but a secret war that spanned a hundred years and targeted the Chinese dragon veins.
From the guarding of the Yangtze River Dam to the backlash of the ancient blood sacrifice in the Kunlun Tunnel; from the invisible spiritual confrontation during the epidemic, to finally launching the "Battle of Dingding" with various foreign coalition forces in the Taiwan Strait to determine the fate of the country. What Lu Yan protects is not only the geographical boundary, but also the lifeblood of civilization inheritance.
