Devil's Contract 1

I was an ordinary urban worker until an accident happened and I signed a contract with the devil. I thought I would be carefree after gaining superpowers, but I didn't expect that the price behind becoming a contractor would be so huge. Human sin and bloodthirsty instincts would pull me into the abyss step by step. That girl, from the first time I saw her, I couldn't forget her. I tried my best to protect her, but I faced many difficulties - the disparity in status, the indifference that prevailed in human society, and the contractors who were like me lurking in the dark, all became obstacles on my way forward. In this bloody storm, who can have the last laugh?
