The Primordial Nightmare seemed to sense Rosvisser's opposing primal energy, making it even more ferocious. It ceased its chaotic attacks on the surroundings and focused all its energy on its chest. A black and red magical orb formed there, radiating a violent, suffocating pressure.

Even during the energy charging phase, Leon could already feel the unprecedented power of this strike. He stepped forward, gathering lightning magic to assist Rosvisser, but Claudia held him back.

“What’s wrong?” Leon asked, turning to her.

“A clash between primal forces—your usual lightning magic won’t help here,” Claudia said. “And that black dragon scale is peculiar. I doubt any conventional magic could affect it.”

Leon gritted his teeth. Though unwilling, he understood Claudia’s explanation. If he acted impulsively, not only would he be unable to help Rosvisser, but he might also create unnecessary complications.

With that realization, Leon stepped back, raising his arm to shield Claudia as magical energy surged, forming a blue skeletal framework around them.
