Wu Hen reached into his own chest and pulled out the Sword of Death Omen from within.
The black, shadowy blade resembled a nimble Witch Dragon, its slender tail winding around Wu Hen's arm, fusing with his bloodline. The dragon's lean and fierce body transformed into the Cold Curved Sword. Around the blade, red phantom-like fibers coiled like sacred down, or perhaps like ashes formed from the heat of the blade...
The speed was swift, almost a flash. As the blade swept past like a dragon through water, its majesty was overwhelming. The Mourning Robe Sky Rhinoceros, under the oppression of the Law, was likewise unable to discern Wu Hen's movements, merely feeling as though a living Heavenly Dragon had unleashed its claws, pouncing towards it, the chill piercing into its soul, mysteriously spreading throughout its body, freezing its joints solid.
"Whoosh!"
