Ning Tian guarded the Demon Suppression Pass for hundreds of years, using his divine power to protect the peace of the human race. However, his parents forced him to give the credit to his younger brother Ning Chen, and he was also asked to give up his position as the Demon Suppression Pass and the Prince Consort. The cold-hearted Ning Tian signed a letter of disapproval and left. After Ning Chen pretended to claim the credit, the demon clan invaded in large numbers, the demon town gate was lost, and the human race was plunged into catastrophe. At the critical moment, Ning Tian showed up to kill the Demon Emperor, but he did not forgive his family. In the end, he led an army of eight hundred demons and set off across the sky to pursue a higher road.
