The Yao Birdling navigated the smoke, following its senses. As for its rider and Gui Xa, they were blind. They couldn't sense anything because the smoke messed with the aura.
"We will be upon him!" The rider informed Gui Xa.
The Yao Birdling opened its mouth, ready to bite. The rider swung his weapon, which was a long glaive. Gui Xa, who was riding behind, ready his spear to stab.
Amon came into view then. The second they spotted Amon, Amon also turned to them. Amon swung his black dagger at them. However, something was different with the dagger. A black flame was engulfing it. This black flame made the dagger look like it was a black longsword.
This black flaming longsword made contact with the rider's glaive. The black sword went right through without any resistance. The glaive split and the black sword didn't slow. It continued slicing through the Yao Birdling and its rider, cutting both in two.
