Zhang Yueran, a genius disciple of the Qingyun Sect, the leader of the righteous path, was originally a successor of the Immortal Way with high hopes. However, because he was pregnant with the blood of the ancient demon clan, he was slandered by the sect, betrayed by his best friend, and died tragically of his beloved. In a desperate situation, he was expelled from the sect and sent to endless purgatory. When she was about to die, the remnant soul of the ancestor of the demon clan awakened and used the essence and blood as a guide to help her break through the shackles and transform into Shura. From then on, the righteous way was a blood feud for her, and the immortal way was a yoke of hypocrisy to her. Zhang Yueran returned with demonic flames, crushed the blue clouds, stained the sky with blood, took demons and ghosts as servants, controlled demonic beasts as riders, gathered the remnants of the demon world, and built the Burning Heaven Demon Court. With the creed of "Those who follow me will prosper, those who go against me will perish", she kills immortals and gods along the way, breaks the order of the three realms, and finally becomes the supreme overlord with demons in the world. When the cold demonic flames illuminate the nine heavens, the world will realize that the so-called hypocrisy of the right path and the so-called ferocity of the demons are just excuses for the weak to prey on the strong - and she, Zhang Yueran, will reshape the laws of heaven and earth with the power of demons.
