The moment the thought came to him, Lu Xuan acted on it. He instructed the Grass Puppet to keep proper watch over the spirit field, then entered a Quiet Room.
He adjusted his condition to its peak and took out that section of Dark Gold Skeleton.
A wisp of Platinum Flame slowly drifted out from within him, continuously roasting the Purification Glazed Red Phoenix Bone before him.
Several days later, under the combined effects of Lu Xuan's Spiritual Sense and the Pure Yang True Fire, the Purification Glazed Red Phoenix Bone softened slightly, becoming like a puddle of dark-gold liquid that gradually seeped into Lu Xuan's body.
Looking inward, the dark-gold liquid silently merged into Lu Xuan's bones, causing countless dark-gold specks of light to appear across the bones throughout his body.
The specks of light flickered faintly and were slowly absorbed into the depths of his bones.
As more and more dark-gold specks of light merged in, Lu Xuan sensed a scorching aura surging out from within him. He could not help but take a deep breath, and a rolling wave of crimson heat rushed out.
"Consider the Purification Glazed Red Phoenix Bone preliminarily integrated into my own bones. But if I want to fully fuse with it, it'll still take a very long time."
Lu Xuan rose and went to the spirit field.
Over the next two months, after completing his tasks of nurturing spirit plants and feeding Spirit Beasts, he placed his focus on fusing with the Purification Glazed Red Phoenix Bone.
On this day, after the fusion was complete, Lu Xuan felt the bones within his body growing increasingly hard and faintly crimson. With a thought, Pure Yang True Fire surged from his fingertip.
Platinum Flame covered his fingertip, constantly shifting into all kinds of forms.
