The blood moon is in the sky,and the devil invades.In this world where people kill people,and even people are not human,killing is my means of self-protection,indifference is my strongest armor,andstrength is the only guarantee for my survival!On the majestic earth,hunt powerful monsters,experiece the dark ness of people'shearts,experience the most desperate wars,and look for insignificant light and hope! This is an era where heroes emerge in large numbers,this is acruel story,and this is a....contest with no hope in sight.
