"What...What kind of power is this?!?!" Dark Sky screamed hysterically in desperation and panic, not only from the pain, but also from fear!!
People often fear the unknown. That was why a lot of big, muscular men were terrified of ghosts and other supernatural things. To Dark Sky, Sheyan's 'Extinction' ability was something completely unknown to him, so he naturally felt lost and afraid.
Dark Sky soon realised that, although most people would have already given up on him after he teleported to the top of another hill, but the opponents he was facing this time were rapidly approaching him again. More terrifying was the fact that all the mounds and stones blocking their way would bizarrely shift to the side, while some shallow ravines would fill themselves up! Those people were thus dashing towards him in a straight line!
