After My Sister Died, I Became the Fourth True Ancestor.

Chen Wen and his sister were once the kindest people in the world, but... Kind people will not be rewarded well. When Chen Wen killed his pursuers and knelt in front of his sister's body with a guilty look on his face, he secretly swore that he would never be a good person again. No, he doesn't want to be a human anymore! With sharp fangs and jet-black wings, Chen Wenrong, who transformed into the Fourth True Ancestor, appeared in the night. He was about to start his revenge career to hunt those who fell into the darkness.
