Cannibalism

After its sinister proclaim, the ancestral spirit fell silent once more.

Benjamin furrowed his brows.

…... It's still just an ancestral spirit, why was it being so difficult?

He turned around and glanced at the thin red barrier. Its integrity was much tougher than he thought. The System just conducted an urgent analysis and soon notified him that aside from spiritual energy, there existed many other unknown substances. The System couldn't determine what these substances were, which naturally meant that it had no way to counter them.

With no way to counter, he had to rely on brute force alone.

Benjamin quickly arrived at the entrance and threw everything he got at it. Whether it be the various elements he had at his disposal, or Elemental Order - Damage... aside from "Descending of Water", he used every other technique that he had up his sleeve. But still, the wall remained unfazed.

It was similar to Mile's magic-immune physique.
