The Replica Wall of the Supreme Demon Wall was still here, and Huang Xiao wanted to make good use of it.
He knew the Patriarch might summon him at any moment, and he certainly could not take the Replica Wall with him. When that happened, he would no longer be able to enjoy the benefits of having demonic qi pour into his body.
The Replica Wall of the Supreme Demon Wall had already been moved into an adjoining secret chamber, connected to this one by a stone door.
Huang Xiao pushed the door open and entered, seeing the Replica Wall in the center of the chamber.
Letting out a long breath, Huang Xiao walked over to the Replica Wall and sat cross-legged before it. He did not immediately activate the supreme demonic qi, instead preparing to refine his Heavenly Demon true qi first.
He circulated his internal power while sitting cross-legged, and only after quite some time did his emotions settle.
With a thought, he activated his essence blood. It surged toward his heart, and heart fire arose.
Huang Xiao controlled his heart fire, letting it seep into his meridians, then began using it to temper his Heavenly Demon true qi.
Under the scorching heart fire, his Heavenly Demon true qi soon began to change. The Heavenly Demon true qi that had filled his meridians rapidly contracted and diminished. Its quantity decreased, but its aura grew stronger.
As he continually activated his essence blood, heart fire kept forming. The meridians within Huang Xiao's body could be said to be filled with heart fire, which constantly tempered the unrefined Heavenly Demon true qi newly flowing in from his dantian.
Having experienced this several times, Huang Xiao now handled the process as easily as driving a light carriage down a familiar road.
