In ancient times, when chaos first emerged, the world was filled with clear and turbid qi. The turbid qi was stronger than the clear qi and first formed a human being, named Qiongming. After Qiong Ming was born, he fed on turbid air. In order to create more turbid air, he abused his divine power, controlled the turbid air, created demon soldiers, and drove away the pure air. He attempted to demonize all people in the world and create a world with only turbid air. The world was suffering under the control of the demon god Qiong Ming. Heaven created thirty-six ancient gods to fight against Qiong Ming, but Qiong Ming had the power to destroy the world and was immortal. In the war between gods and demons, he destroyed thirty-two ancient gods and sealed Qiong Ming in the Xuanming world. Since then, the immortal world, the mysterious world, and the human world have entered temporary stability. Millions of years later, the pure air between heaven and earth condensed at the intersection of the three realms and transformed into a human being, named Ranchen. Tianzhongtian is a new world formed by the intersection of the three realms. The Qing Qi here is strong and isolated from the world. Ranchen was born here and is ignorant of worldly affairs. One day, Yunhe was traveling in the lower world, accidentally broke into Tianzhongtian, and brought Ranchen out of Tianzhongtian. Since then, the two have been traveling together, getting to know each other, and falling in love. However, as Yunhe is the prince of the fairy clan and has a family mission, Ranchen is dyed in the mortal world, and his identity is unknown. Their relationship is hindered along the way. Later, Yunhe died in an accident. In order to save his lover, Ranchen violated the laws of heaven and forcibly rebuilt his body. After going through many hardships, Yunhe was resurrected. However, Ranchen was tainted with turbid air and could become a demon at any time. In order to awaken his lover, Yunhe entered Ranchen's consciousness, changed her memory, and expelled the turbid air from her body. Ranchen was rescued and returned, but Qiongming broke through the seal and once again harmed the three realms. Ranchen defeated Qiongming, and the three realms were stable since then.
