After attempting to inscribe Soul Skill patterns, Huo Yuhao discovered an additional benefit: the process of inscription could actually train his Spiritual Power.
What Douluo Continent lacked most was methods for cultivating Spiritual Power.
During inscription, Spiritual Power flowed in winding currents and intertwined with Soul Power. It could not be paused midway, so he had to remain vigilant at all times. Yet because of this, he became extraordinarily focused, nearly reaching a state of deep concentration free from outside interference.
Unlike engraving a Soul Tool's Core Magic Array, Soul Skill pattern inscription did not consist of just one layer. The Soul Power released for the inscription was continuously added as the process progressed, eventually forming one layer of patterns on the surface, one in the center, and one at the deepest level—three layers in total, like a sandwich cookie.
The deepest layer had the most intricate lines. Upon close inspection, one would find that these inscriptions combined to depict the Soul Beast performing a certain action. That was why this layer tested the inscriber's Spiritual Power so severely; it was practically akin to drawing.
This step determined which Soul Beast the Soul Skill originated from.
The patterns in the central layer were instead the simplest. Their sole purpose was to serve as valves. When a Soul Master released a Soul Skill, their Soul Power would flow from the deepest layer, pass through the valves in the central layer, and finally be guided to the patterns on the surface layer.
The valves could be large or small, allowing Soul Masters to control a Soul Skill's power more precisely when releasing it, rather than having to consume a considerable amount of Soul Power every time they used one.
The surface layer's patterns were rather special and could be understood as a
