Chen Nianzhi murmured, unable to hide his delight.
The vein was not particularly high-grade, but it held an immense quantity of ore. In the mortal realm, it could produce hundreds of millions of Magic Treasures and Spirit Treasures—more than enough to forge several Magic Treasures for every cultivator in the entire Purple Yin Realm.
To Chen Nianzhi, these spirit ores were too low-grade to forge Immortal Treasures. But he could refine them into the purest Magnetic Metal Baleful Energy.
Great White Geng Metal was one of heaven and earth's extraordinary metals. Immortals with sufficiently advanced techniques could refine it into Magnetic Metal Baleful Energy.
That energy was the purest form of magnetism. A small quantity was of little use, but with enough of it, it became the perfect auxiliary material for refining a Heaven-Opening Treasure.
"A vein stretching tens of millions of li... Once refined into Magnetic Metal Baleful Energy, it should be enough to help the Yin-Yang Void Mirror advance."
Chen Nianzhi murmured and took out the Yin-Yang Void Mirror.
The Yin-Yang Void Mirror was sentient. As soon as it sensed the Great White Geng-Metal Ore Vein, its light quivered, revealing its yearning.
"If this can help you advance, then devour it to your heart's content."
Chen Nianzhi spoke calmly and took out the Heaven-Opening Qi, allowing it to merge into the Yin-Yang Void Mirror.
After absorbing the Heaven-Opening Qi, the Yin-Yang Void Mirror's light trembled. An indistinct shackle opened, and in an instant, it radiated Yin-Yang Magnetism.
Wherever the Yin-Yang Magnetism passed, the Great White Geng-Metal Ore Vein began to magnetize. The ore gradually broke down into a vast sky of Magnetic Metal Baleful Energy, rising like billions of streams of stars and flying toward the Yin-Yang Void Mirror.
"Not bad."
Chen Nianzhi nodded slightly, looking pleased.
