the appearance of the dao pattern meant that these wood spirits had already undergone a qualitative improvement.
currently, wang shuo had only seen the existence of dao patterns on the bodies of legendary heroes. however, even their dao patterns were only inscribed on life-bound precious artifacts.
this was because dao patterns were the manifestation of the laws of heaven and earth, and their bodies couldn't bear it.
unless they could advance to rank-3 and completely transform their taoist body into a conjured body.
Only when one's physical body turned into a dharma body could one start to bear the Dao patterns and master the divine arts.
The wood essence was different because it was a part of BA Tianrong. As a spiritual root of heaven and earth, BA Tianrong was a creature born from the laws of heaven and earth, so he could naturally bear the laws of heaven and earth.
