Song of the Demon King

Demon King, the king of the demon world. It is usually used to refer to darkness and evil, and it is often regarded as the mortal enemy of mankind. But is this really the case? The number of humans who have died at the hands of the devil over the past thousands of years may not be even one billionth of the number who have died at the hands of other humans. What's more, the legendary demon king was actually just a human being. Therefore, the mortal enemy of mankind has never been the devil, but mankind. The seductive and depraved song of the devil is nothing more than an illusion of human beings' endless desires. The most terrifying devil never lives in the devil world, but in the hearts of humans.
