After more than three hundred years of seemingly peaceful life among the three races of humans, demons, and demons, the demon race took advantage of its strongest power to provoke a war, but they did not expect that stealing the chicken would end up losing the rice. After the war, the demon clan declined, the human and demon clans signed a peace treaty, and the demon clan all returned to the demon world. At this time, the person with the most embarrassing position is the mixed race. If you return to the demon clan, not to mention whether you will be ostracized by your own clan, the half-human blood in your body will have to endure the pain of demonic corrosion day and night, so most of the mixed-bloods stay in the human world. Those who are not of my race must have different minds. Humans cannot fully accept hybrids.
The great exorcist who was famous during the war suddenly disappeared twenty years ago. Twenty years later, his weapon spirit began to look for his successor according to his instructions. Now the peace gained due to the demon clan's withdrawal from human territory has been broken again.
