Ah? I Am in the Demon Suppression Division, and My Mother Is the Demon King?

There has been blood and fire for thousands of years, and humans and monsters are at odds with each other. Lin Ye, a small official in the Demon Suppression Department, has become the biggest anomaly in the world. He hid in the Demon Suppression Department and used his civilian job to investigate the mystery of his life experience. I originally wanted to be caught between the human race and the demon race, but I was forced to use both sides. When the human race regarded him as a spy of the demon clan and set up a dragnet to hunt him down, a decree suddenly came from the Ancestral Court of Ten Thousand Demons: "My son, you have had enough fun, it's time to come back and inherit the family property!" Lin Ye was stupid. I killed so many monsters, but in the end, all I killed were my own people? Looking at the demon-slaying sword still stained with demon blood in his hand, Lin Ye fell into deep thought. Is it too late to say that I am also a demon clan?
