Steel Qigong (鋼気功) is a magic technique that uses Qigong to apply a layer of magic armor created by Lu Gonghu himself. He often uses it to reinforce his hands to block attacks and as his weapon of choice for attacking. The technique involves covering the desired area of skin to be reinforced with a high density of Psion's, which is the same as fortifying the Eidos of the skin. Steel Qigong can also be used for Data Fortification.
