As Li Yun comprehended this, his Lightning Intent began to tremble.
The lightning around him became increasingly intense. Black thunder filled the cave, and every arc seemed to be testing his understanding. If his comprehension was shallow, he would be harmed by the lightning. If his will wavered, the destructive thunder would invade his mind. But if he could grasp the true essence hidden within it, his Lightning Intent would undergo a tremendous transformation.
Li Yun's breathing gradually became steady.
His mind sank into a strange state.
In his perception, the cave disappeared. His body disappeared. Even the pain flowing through his flesh faded into the background. All that remained before him was a boundless sea of black thunder.
