Demons and humans have coexisted in the human world since ancient times. Mortals, heavenly masters, monsters, and blood demons between humans and monsters struggle to coexist in this area. Two hundred years ago, the demon army rose up, and the previous emperor besieged the capital. The human race is in danger. Zhang, Wang, Li, Chen, and the five heavenly master armies from the left gathered together to drive away the demon race and regain the lost territory. After the world settled down, they all supported the Zhang family as the emperor. The Wang family stayed in Kyoto to assist the Zhang family because of their decline. The other three families were divided into various places. From then on, the art of exorcism and demon elimination was mastered by the nobles of the royal palace. Until eleven years ago, the demon clan raided Yuezhou and Kyoto. The Chen family in Yuezhou fought bravely to kill almost all the enemies. Only the legitimate son of the Chen family who was in Kyoto at that time saved the capital from the fire and led the army of heavenly masters to invade Yuezhou to eliminate the demons and bandits. Nowadays, everything is peaceful on the surface, but there are undercurrents surging underneath.
