The cosmos splits into two hostile halves: an outer universe ruled by demons, and an inner universe divided into the Realm of Gods, the Eternal Realm and the Mortal Realm. Countless mortal worlds, the Tianfa Continent among them, make up the Jiutian Xin Region. There, nine immortal emperors hold sway over the star fields across nine layers. Beyond the nine heavens lies the purification realm of the immortal gods. Ni Tian Zhizun is a long-running action fantasy ONA spanning 580 episodes.
