Dragon's Pulse

In the land of Xing, one of the people's basic philosophies is that there exists a flow of life energy within the earth (signified by the mystical dragon), flowing metaphorically from the tops of mountains down to the land, nourishing everything it passes with that energy as does blood coursing through the veins. This energy is called the Dragon's Pulse (or Lung Mei). As such, this energy is prevalent in all things as well and breathes in rhythm with life forms and nature. While this philosophy is a central concept to the ancient Xingese art of Alkahestry, it can also be understood and manipulated by those who do not practice the craft. Royal warriors of Xing's fifty clans are taught to read the flow of the Dragon's Pulse, thereby becoming not only able to commune with nature and understand their surroundings, but sense the presence and movements of the people and animals around them as well by reading the pulse of life energy within their bodies.

It is with this power that the Xingese warriors Ling Yao, Lan Fan and Fu are able to sense the many spiritual anomalies in Central, including Alphonse Elric and the energy of the various Philosopher's Stones. The Ishvalan Scar has an array signifying the Dragon's Pulse tattooed on his right arm, mixing the Alchemical runes of Amestris and Xing with an Alkahestric energy source to allow for powerful and unhindered transmutations.
