Five hundred years ago, the ten great Demon Lords of the demon race used ancient secret arts to trap him. After a hundred days, both sides fought to the death. Before they died, the ten Demon Lords shouted in delight: "Ten of us for one of you. The rise of the demon race is just around the corner!" Today, five hundred years later, a wage slave whose birthday falls on the summer solstice is chosen by a female CEO, who offers him a great job with weekends off and a monthly salary of over ten thousand! (Lin Fei: Author, speak like a normal person. How can anyone have weekends off like this? Monday through Friday are the days off, and the weekends are when I have to work. Every time I wake up, I feel like my life's been drained out of me. And you still have the nerve to call this a good job?) Ahem! That's not the point. The point is, demons! The Heavenly Court's greatest war god, the one who kept you awake at night, has returned. (The former ten great Demon Lords: ??? So we died for nothing?)
