"Is that... a thundercloud?"
Gazing at the enormous mass of pitch-black clouds that all but blotted out the entire Demon Phoenix Nest, Phoenix showed a trace of astonishment.
Thunderclouds forming over pills were perfectly normal to them. After all, even a Seventh-Rank Pill could summon pill lightning.
But thunderclouds forming during artifact refinement were something even a powerhouse like Phoenix had never seen before.
Never mind a Dou Sheng of the Heaven Demon Phoenix Clan like her-even many of the Dou Sheng among the Ancient Eight Clans would probably find it difficult to witness a lightning tribulation brought on by artifact refinement.
After all, the ancient artifact refining dao had declined long ago. On the present-day Dou Qi Continent, the number of powerhouses capable of refining saint relics probably would not exceed the fingers of one hand, even counting Xiao Yan.
And because the materials needed to refine saint relics were probably no less rare than those required for Ninth-Rank Mysterious Pills, if not even more precious, only one saint relic would often emerge every few hundred years after ancient times.
Yet the lightning tribulation brought forth by this saint relic seemed scarcely weaker than the pill lightning produced by refining a Ninth-Rank Mysterious Pill-or even a legendary Ninth Grade Golden Pill.
As the boundless black thunderclouds covered the entire Demon Phoenix Nest, a golden lightning bolt a hundred zhang long suddenly struck viciously toward the wings, which were only a few zhang in length.
"Nine Profound Golden Lightning!"
Xiao Yan faltered slightly as he watched the enormous lightning bolt descend from the sky, then a trace of delight appeared on his face.
The ancient artifact refining dao also divided saint relics into four tiers: lower-grade saint relics, middle-grade saint relics, and high-grade saint relics.
Their counterparts among Ninth-grade Pills
