Of the two, Jiang Linglong's artifact-refining skill had barely reached the eighth-tier upper grade, while Li Yan Divine Spirit's skill was nearly on par with Chen Nianzhi's.
With the combined strength of the three of them, the chance of refining this treasure was no less than sixty or seventy percent.
Moreover, with the supplementary item Chen Nianzhi had prepared—a bottle of Taiyi Divine Water capable of increasing the success rate of artifact refinement—he believed they could attempt to refine this external core.
Having made up his mind, Chen Nianzhi immediately said, "Once the treasure is refined, I will certainly offer Divine Lord a reward."
Li Yan Divine Spirit merely shook his head and replied calmly, "I am but a lone wanderer. Ordinary external possessions are of no use to me."
"There is no need for a reward. I only hope that when I break through to Taiyi one day, and you guard me during my breakthrough, you will give it your all."
Chen Nianzhi exchanged a glance with Jiang Linglong, then smiled. "Divine Lord is so generous. Naturally, I will not let Divine Lord down."
With that said, the three soon arrived at the artifact-refining chamber and began refining the external core.
This time, Chen Nianzhi took the lead in refining the external core, with Li Yan Divine Spirit and Jiang Linglong assisting him.
With three such accomplished artifact refiners working together, and using the fire vein of a top-grade Blessed Land to refine it, they spent three thousand years before finally melting down the Primordial Nether Dragon Pearl.
Yet at this point, Chen Nianzhi discovered that the Primordial Nether Dragon Pearl's origin had been greatly depleted. He immediately added the supplementary material, Taiyi True Water, to replenish the Primordial Nether Dragon's origin and purge the impurities within.
