Not only was the entire surface of the rock dragons made of an indestructible metal texture...
But their scales also had a honeycomb-like design and super energy-absorbing structure that flashed with a magnificent rainbow light.
Plus, the rock dragons' fangs and claws appeared to have a crystalline texture.
It was as if their creator and manipulator had extracted all the spirit crystals from millions of rocks and molded them into a deadly weapon.
Such spirit puppets could no longer be described as "rock dragons."
They were crystal dragons made of metal and crystals!
Thousands of runes appeared below the scales of the crystal dragons, driving them to ensnare the mentally deranged superhumans.
In the beginning, the superhumans had been like wild beasts that had lost control due to their fury. No one could stop them from dying together.
