Amberser had seen dragons of such immense size before; the Magic Dragon Armament's transformation into a Time Dragon was roughly this size.
However, because the Bone Dragon had lost its flesh and blood, it appeared much "slimmer."
But no matter how slim it was, the Bone Dragon's claws were still larger than Amberser's entire body.
Amberser carefully examined the massive skeleton and quickly noticed several characteristics. A thin layer of light shadow covered the bones, constantly changing colors like a rainbow. Secondly, there was a significant wound on the right side of the Bone Dragon—it nearly severed the entire wing at the root.
This was a Bone Dragon transformed from a Rainbow Dragon, and judging by its size, it must have been an old one that lived during the era of the Magic Dragon Tyrant. The injury on its wing was likely inflicted by those rebellious heroes.
This was a Rainbow Dragon!
