Dozens of Penglai Immortal Beasts gathered together and mumbled some kind of ancient spell. White spiritual power covered the skeletal dragon's body like the glorious sun in the sky. With some kind of purifying power, it tried to force back the black specks.
The originally dusky sky suddenly brightened.
Under the illumination of the light, those black spots seemed to have really restrained a lot, but everyone did not have time to breathe a sigh of relief.
"Bang!"
With a loud bang, all the Penglai Immortal Beasts were blasted away, and a huge black mist came out of the eye of the bone dragon.
A completely black skeletal dragon appeared in front of everyone.
Everyone was dumbfounded, not knowing what had happened.
"It-it suddenly changed color!"
