In the catastrophe 25,000 years ago, the demon world and the heaven were fighting in darkness. This catastrophe also spread to other realms in the six realms, especially the more fragile human realm. In the human world, due to the impact of this catastrophe, demons and monsters are everywhere, natural and man-made disasters continue, and the human race is in dire straits. If Feng Yixie, the emperor of Ming Yuan who had been living in the Changli Palace of the 23rd level of heaven for a long time, had not come forward to challenge Demon Emperor Jiuyue, this catastrophe would not have ended so easily. I am afraid it would have intensified and eventually turned into a war between the six realms. As a result, the supreme Ming Yuan Emperor Feng Yixie, who was already extremely noble in the Six Realms, was "promoted" to become a more mysterious, ethereal, audible but unimaginable legend.
