Ah Dai knew that the entrance to the Demon Realm was about to open, he absolutely could not delay here, holding his Sumeru Sword forward, it's imposing aura directed at Nazgul. He felt clearly that although Nazgul had not died in the previous joint attack by everyone, his main body was certainly heavily damaged and he hadn't yet recovered.
Feeling the enormous energy emanating from the Sumeru Sword, the black fog gathered by Nazgul suddenly shrank. A human-shaped formation of black fog appeared. He inexplicably conjured up a black cloak to cover him. It made him look like a wizard from legends. A hand made of fog waved in the air, and suddenly three Fire Sprites appeared. They wielded Fire Whips in their hands and charged toward Ah Dai.
