There is a "living dragon vein" hidden in the land of China, and the tombs of emperors of all dynasties were built based on the dragon vein. The dragon vein is not only a Feng Shui concept, but also an energy network left by ancient civilizations. Those who control the dragon vein nodes can affect the destiny of the country. The protagonist group is the descendant of the "Pulse Keepers" and competes with various forces (overseas consortiums, mysterious organizations, and traitorous Pulse Keepers) who covet the dragon's veins.
