Shi Tianhao activated his Purple Skull of Angmao. In it, a powerful thunder-type spiritual energy fused together with the Primordial Magnet Power in the mine and created a terrifying sound.
"Duo!" Shi Tianhao said in a low voice as a powerful Qi pillar, that seemed to be made out of clear and yet impure Qi, appeared from his forehead. It then enveloped his body and turned into a huge, Primal Taiji Diagram image.
In the Taiji Diagram, one could see countless images of ancient beasts and an ancient, primal power began to spread.
The Purple Skull of Angmao combined with Shi Tianhao’s Immortal Soul Avatar and powerful thunder light flashed non-stop. Combined with the vast amount of Primordial Magnet Power in the mine, it was a truly terrifying scene.
Runes made from thunder appeared one after another on the Taiji Diagram. Slowly, they turned into a terrifying giant spell formation.
