There was only one red king in this world. But who would have thought... it turned out that there was more than one ruler of nature in this world, and one of them was the blue king.
In contrast to the red king's central element, which was fire energy, the blue king's main element was ice energy. The two of them were so contradictory to each other that they couldn't be within a close radius. Their life power would hurt and make each other weak.
It's different from humans. If the two kings' energy attacks directly hit humans, ordinary humans would immediately die. Human skin would melt and melt formless when a human was exposed to fire energy. Conversely, if it were exposed to ice energy, the human heart would freeze, causing absolute death.
This explained why recently, they found lifeless bodies with frozen hearts. It looked like the blue king was the cause of their death.
