—Whoosh...
*Boom!
The blurry sight of two female figures flying past the rocky plains was soon accompanied by the resounding sound of a sonic boom indicating that the girls' flight speed had broken through the sound barrier. Indeed, they were currently flying at a speed several times the speed of sound, and yet, their journey to the Darkin mountain range would still take them more than six hours.
Worst of all, flying wasn't exactly the safest mode of transportation in the wild and dangerous demon continent as evident by the giant Thunderbird that was currently chasing after them. The bird resembled a giant bald eagle with ice blue feathers and cracks of electricity dancing on its massive body.
The bird measured about 30 meters in length and its talons were as sharp as blades. Flapping its massive wings, it let out a thunderous high-pitched call as it chased the pair with supersonic speed.
