Begin The Formation

Cain's understanding of Divine Lightning Laws became more fundamental. The flow of lightning, which was both berserk and calmly smooth, the destructive force behind it, and the vital essence mixed within, all these principles smoothly fused into Cain's Spiritual Sea. 

If not counting the highest complex Dao Principles such as Space, Time, Chaos, or other peaks nomological truths, the Dao of Lightning is recognized as high-tier in complexity. 

It's why, despite Cain facing many foes with elemental Laws, it was a bit rare to see one actually cultivate Lightning Laws. 

Cultivators who attempt this path simply can't get far on it. Whether it was the difficulty in controlling lightning flow, tempering its berserk energy principles, or handling its innate destructive force, Lighting Laws have an extremely high stage of comprehension threshold. 

Many end up abandoning Lightning Laws altogether or ruining their own cultivation with uncontrollable lightning.
