Phoenix Dao Fire burns everything; its lethality towards Soul Ghosts, a yin spiritual body, is unquestionable.
Many cultivators, after death, become Soul Ghosts, fearing even sunlight. The midday sun could massively harm Soul Ghosts, and only those at the level of Day-wandering Ghosts can be fearless.
Chen Dengming's Divine Spirit, of course, does not fear sunlight, nor does it fear many fire-based Skills. Even Phoenix Real Fire may not necessarily cause much damage to his Divine Soul now.
But the difference between Phoenix Dao Fire and Real Fire is extreme.
Now, as Chen Dengming's Divine Spirit comes into contact with the Phoenix Dao Fire swirling around the exterior of his Dao Body, by merely touching slight edges, he immediately felt an intense, heart-searing agony.
He quickly drew back his Divine Spirit after a brief attempt.
