Shi Zongyue and the other Immortal Soul stage elders fixed their gaze on Xiao Budian as he formed the symbol for the Eight Trigrams through absorbing spiritual energy.
Normally, a cultivator's spells were monotype. After they passed into the mid-Aurous Core stage, they could also only manipulate one type of spiritual energy in the environment around them.
For better mantras, cultivators that had perfected them could use more than one type of spiritual energy from the environment around them.
For example, the Great Qin Empire's Secret Manual of the Five Imperial True Dragons could allow a mid-Aurous Core stage cultivator, who had perfected all five of its components, to manipulate five different types of spiritual energy and form five true dragons. They could harness the powers of metal, wood, water, fire and earth, and were considered to be the top of their league.
