In the second year of Xuanhe at the end of the Northern Song Dynasty, the heavenly "Hunyuan Yi" that originally suppressed demons was accidentally opened, causing 108 stars (positive stars) and 108 evil stars (devil stars/demon stars) to scatter in the world. The order of the world is in chaos, and demons are rampant. Heaven specially sent two disciples of Beidou Xingjun, Zilong (senior brother) and Chen Hu (junior brother), to go down to earth for training, and shoulder the important task of recovering the stars and quelling the disaster.
