The incubus had his whole face being incinerated yet his body was simply refusing to feel any pain. Rather than feeling a pain, he was simply converting all his emotions to the lustful ones increasing his 'dual cultivation'.
That's why, the waist of the incubus was roaring as he continued to please himself and the lady.
This is one of the incubus techniques - Desire Change!
The victims of the incubuses and succubuses had their emotions all controlled tightly. This is what the incubus also tried to use on Xia Feng, but with even more additional techniques. In the end, he became the victim of his own technique as his opponent was the erossu himself.
Xia Feng had a lot advantages here as he knew very well about his circumstances unlike the incubus!
