The street on a rainy night. Wearing a black windbreaker, the brim of a hat covered with water dripping half of his face. Holding a bloody long knife in the palm of his hand. The revolver in the leather case is about to move. The burning cigarette has not yet landed. The evil roared in fear and anxiety... This is the story of the traverser Cole Walker, who came to a world full of dangers and became the strongest demon hunter by virtue of the heavens descending system. Punch the evil spirits, kick the devil, and start the story of a cool life.
