Under normal circumstances, ice and fire couldn't possibly appear at the same time. If they appeared at the same time, one of them would tend to be weaker. However, the "ice" and "fire" used by the two half-celestials were no ordinary techniques.
The hot and burning lava mixed into one with the bone-chilling half-ice crystals. The reddish gold and bluish-white mixed and both soon canceled each other out, but in an instant, clusters of ice spirit fire were born.
Almost in the blink of an eye, the entire space was filled with four-colored ice spirit fire, and it would bring others the painful experience of being frozen while being burned at the same time.
It was an extreme experience as if one had fallen into an ice cave and been cut by a thousand cold blades, then in the next instant, one was roasted by fire and had lava poured into one's bones. It was worse than death!
