Dragon's Pulse

Dragon Waves are used in Alkahestry/ Rentanjutsu, the Alchemy of the country of Xing. We are first shown how Dragon Waves are used when Mei Chan throws Kunais (Japanese throwing knives) at a collapsing mine. The Kunais then make a transmutation circle on the mine entrance. Mei Chan then creates a transmutation circle with in the dirt idinticle to the pattern of the knives. She then performs Alchemy and rebuilds the collapsing mine, saving the men inside. Mei Chan did that by sending 'dragon waves' through the earth, from her transmutation circle to the transmutation circle formed by the Kunais.

A dragon waves tattoo is also featured on Scar's right arm and left arm, as the Dragon Waves can help Scar use Alchemy, even if it is Scar's first time using Alchemy. This may cause some of you readers to wonder how Scar has Xingese tattoos on his arms, but it should not be forgotten that Scar's intelligent brother had studied Xingese Alchemy for a long time and had even discovered the Xingese Human transmutation circle.
