The first deployment of the Death Scorpion's sand controlling power sent streams of sand flying into the air, forming sharp arrows which pierced through each demonic corpse, or directly slicing them open, making easy work of clearing a large number of corpses.
However, the amount of sand the Death Scorpion can control is limited. It isn't capable of launching an infinite number of attacks at once.
To Du You's disappointment, its control over sand isn't very flexible. It can only manage basic transformations and attacks. Any special effects are entirely absent.
Du You sighed helplessly, realizing it might take a while before he could use the sand in the way he had imagined. The current abilities of the Death Scorpion were far from meeting these requirements.
As for the Cursed Crow King, it seemed to have no effect at all. His own Curse Aura was practically ineffective against the demonic worm-controlled corpses. Any impact it had was marginal at best.
