Just like someone pouring ink into clear water, the darkness spread into the surroundings. Facing the blazing spear of the sun slashing down upon it from above the sky, the black dragon instantly beat its wings contaminating the sky with its dark purplish Chaos powder at an attempt to hide its own body. Under the interruption of that magic power, every means of communication would be isolated and blocked. Even the divination spell would not be able to locate its whereabouts.
However, the black dragon's effort did not do any good. Joshua had already locked on to the its breath and presence.
Upon completing the Class quest of the Chaos Guardian, the warrior had acquired the two Gifts called [Flare of Purification] and [Nemesis of Chaos]. Both of the Gifts could allow the warrior to see through the dark purplish Chaos power and mist. Whatever the black dragon attempted to do, it just seemed like a pointless attempt to struggle to Joshua.
