The owner of the icy voice was obviously the Ghost Nightmare casting the secret realm. When it spoke, Guding and the others confirmed that this creature indeed had full consciousness. But more importantly, it revealed a crucial piece of information: the base point of the Illusion Realm was hidden inside the blue giant corpse.
The physical body strength of the blue giant corpse was so astonishingly strong that Guding and Berg working together couldn't suppress it, and it didn't even suffer any substantial damage.
The most severe injury was only the deepest cut from Berg, which left a blood mark on its neck, but even that scar healed instantly.
Hiding the base point inside such a creature was undoubtedly a dead-end. Guding and his team couldn't even harm the giant corpse, let alone retrieve the base point from its body.
Upon hearing the icy voice's explanation, the Sea Emperor and the others all turned a bit grim.
