The sword did not work after stabbing in. Roy immediately felt that something was wrong, so he quickly retreated.

The next second, an enormous wave of fire swept toward Roy, almost covering all the space he could dodge. Feeling the violent high temperature contained in the flames, Roy took prompt action and placed a thick layer of black ice on himself.

The fire wave surged and completely enveloped Roy. It carried him hundreds of meters away before gradually disappearing.

Amid the smoke, Roy appeared. The ice on his body had totally melted in the fire wave just now. Kha-Beleth's flame power was more powerful than he had imagined. Had he not continued to output magic power, it might have burned him after the ice melted.
