Su Ran, a person of werewolf blood who was expelled from the Immortal Sect, awakened the inheritance of Tongtian Cult Master at the living sacrifice site, and used moonlight transformation, biting and plundering and other magic to crush the immortal cultivators. He originally tolerated it in order to protect the mountain village, but during the siege of the Immortal Sect, he discovered that the leader of Tongtian was actually the human emperor who was sealed in ancient times, and his blood was actually the last fire to fight against the way of heaven. From pretending to be a pig and eating a tiger to establishing a demon alliance, it finally triggered the Nine Heavens Tribulation to shatter the so-called righteous order.
