The world is divided into three types of people:
1: Monster clan
2: Human Government
Three: Human civilians
In the calendar year 510, due to the corruption of the government, the human race civilians began to revolt. The government could not quell the rebellion, so it asked the demon race to join the war, and the human race civilians were defeated. In the calendar year 512, a human civilian named Fred Matona stole the demon clan's magic, which brought hope to human civilians and led an uprising. In the calendar year 515, the demon tribe discovered an ancient magic that could turn the souls of regretful dead humans into slaves. The king of the demon tribe sent a large number of people to use this magic, which resulted in the death of countless demon tribes, but brought the uprising to a low ebb. [Side effects: A large amount of black elements will swallow the soul, and eventually the soul will be scattered. And this magic is black element magic]
