Dragon Bone Script

The Bone Rune Script: Xiao Yan, whose soul inhabits a beggar's body, discovers that he can carve runes into his bones. He cuts his arm with a pebble, and the character for "speed" on his bone makes him as fast as the wind, while "fortitude" lets him withstand magical artifacts. But he deliberately pretends to limp in front of cultivators, just so he can secretly cover his whole body in runes.
