Within these Enlightenment Tea Leaves, traces of diabolism skills unexpectedly existed.
Because He Song, many years before, had relied on Qing Feng to slay a Nascent Soul of diabolism.
And had successfully refined this demonic cultivator into a Nascent Soul Puppet.
Meanwhile, over the subsequent years, He Songzhen had also been manipulating Ghost Soul, to move within the area of influence of diabolism.
Therefore, He Song was actually quite exposed to the methods of the diabolic side.
Some peculiar diabolic methods had also been learned by He Song, and even used by him.
Under such circumstances.
He Song had a rather profound understanding of certain characteristics formed by diabolic methods.
Just like with the cultivation practice of Spiritual Artifact Refining Puppet Skill to refine puppets, other cultivators who were similarly proficient in this skill would quickly notice if something was amiss.
