Black Contractor

With the emergence of the "Gate of Hell", the beautiful starry sky was covered up and replaced by a false starry sky used to monitor the actions of the "Contractors". "Contractors" are people who gain superpowers after coming into contact with the material in the "Gate of Hell". As a chosen group of people, they are cold and ruthless, making people full of fear and doubt. Various mysterious organizations use the contractors' superpowers to engage in melee for their own benefit. Hei, who was not a contractor, had to join the battle against his will for the sake of his sister Bai, and fell in love with the contractor Amber. But he gradually discovered that Amber had betrayed the organization and himself; after the mysterious incident, his sister also disappeared. The angry Black finally became the real contractor, and was called the Black Death, the cursed contractor. During the execution of organizational tasks, Hei met Amber again, and Amber's words and deeds became more and more mysterious, and it seemed that there were many unspeakable secrets behind the betrayal. In order to find his sister, Hei followed Amber and gradually saw the bigger secret behind the melee. Can Black find his sister? What choice should he make for the fate of himself and his contractors?
