Thousands of years ago, the Drought King led the four evil spirits and a large number of evil spirits to break through the boundaries, wreaked havoc on the world, slaughtered all living beings, and triggered a "catastrophe of annihilation" that shocked the three realms. All living beings in the world were devastated and the right path was in danger. In order to protect the peace of the human world, the ancient divine dragon Yinglong joined hands with Yushi and Xuanming to exhaust all his own origins and kill the Drought King with all his strength; the four elephant beasts did not hesitate to sacrifice their bodies and laid ancient seals to trap the four evil spirits in the four poles of the world. Isolating its connection with the human world; Zhang Tianshi, in order to seal the remaining evil spirits, perished together with the thousand-year-old fox monsters and great Gu masters from thousands of years ago. The great powers of various sects were also killed and injured in this catastrophe, the inheritance was completely broken, and the power of the righteous path collapsed.
Thousands of years later, the world has entered the modern technological society, and 99% of ordinary people are unaware of the existence of evil spirits. As time goes by, the seals of the four sacred beasts gradually weaken, the four evils begin to break free, and the ancient demons are about to awaken; the evil forces gradually recover and begin to cause trouble in the world, snatching resources and sucking the essence; the inheritance of the righteous forces is broken, and their strength is not as good as before. It is difficult to cope with the crisis of the evil spirits' resurgence, and there is an urgent need for new strong men to rise.
