Inside his own Dantian.
The golden Nascent Soul is sitting cross-legged.
In front of the Nascent Soul is a miniature version of the Demon Blade.
Above the Nascent Soul is a small Fire Bird.
This Fire Bird is precisely the Divine Soul Firebird that Zhou Yu painstakingly nurtured.
At this moment, the Divine Soul Firebird is inhaling and exhaling a strand of True Fire.
This strand of True Fire was refined from the True Fire of Quanwu on those Demon Beasts.
After this period of tempering, that strand of True Fire of Quanwu is almost completely refined by the Divine Soul Firebird.
The True Fire of Quanwu is ultimately a Divine Beast Level True Fire.
Once refined, his Divine Soul Firebird will inevitably strengthen further.
Of course, what excites Zhou Yu even more is that the Divine Soul Firebird now possesses considerable Spiritual Wisdom and can independently refine beneficial True Fires.
This is the rarest trait.
