Vortex Fireball!
Song Jian controlled the Black Dragon, casting Dragon Language Magic. A fireball that swirled like a starry nebula ruthlessly slammed into the World Boss, instantly drawing the Boss's aggro to the Black Dragon.
Watching the Black Dragon in mid-air, the Demon Guard Commander let out a low growl and swung its war blade violently. A dazzling red Qi strike cleaved towards the Black Dragon, seemingly tearing space itself.
The Black Dragon flapped its wings, barely dodging the direct hit of the Qi strike. However, it was still injured by the residual force. A large chunk of scales on its abdomen was shattered, resulting in over a thousand damage points floating above its head.
Fury filled the Black Dragon's eyes as it spewed a scorching Dragon Breath towards the Demon Guard Commander. It spread its wings, flew over the commander's head, and ruthlessly swiped its sharp claws at its head.
