Everyone realized that the one wielding the elements of darkness wasn't Hei'An as Holy Son An Juejing thought, but this man whose face was covered in black. An Juejing didn't know about Hei Xiaojing, to be precise they never met at all. After Hei Xiaojing had perished, except for the Gods, no one else remembered him. That's why the Holy Son also didn't know that this man, possibly Wang Yan, is capable of using darkness as his power.
The man in whose face and body was covered in a black cloak chuckles and his voice sounds flirting as he responds to the Holy son's question.
"Why shouldn't I use it? This is something I'm born with~"
Holy Son, An Juejing shouted this man's name in anger, "Wang Yan! What the hell do you truly want?!"
"This time I don't want anything. It's your other selves that want something from you," said Wang Yan.
