In ancient times, spiritual energy was abundant, and the three clans of humans, demons, and spirits coexisted. After the tribulation of the conferment of gods, spiritual energy was exhausted, immortals and Buddhas retreated from the world, the demon clan declined, and the human clan unified the world. Three thousand years passed, the Age of Dharma Ending concluded, and heaven and earth spiritual energy revived once again. The world is divided into the three dynasties of Wenzhao Great Song, Tianlang Great Yuan, and Chihong Great Ming for separate rule. The Central Plains Great Song venerates culture and values morality, with talismans flourishing; the Northern Frontier Great Yuan establishes itself on iron cavalry and shamanic witchcraft, skilled at controlling demonic beasts; the coastal Great Ming has top-tier firearms and mechanism arts, with prosperous maritime trade. The three dynasties temporarily truce, while internal games continue endlessly. The revived spiritual energy awakens thousands of demons and monsters, the demon clan is rising day by day, the three sides' methods of governing demons vary, and conflicts continue to escalate.
