According to legend, after N ü wa repaired the heavens, she left behind some of the repair stones in the human world. The repair stones contain mysterious powers, and evil cultivators in ancient times used them to perform the technique of robbing others' magic and bodies, in order to achieve alternative immortality. However, this plundering technique was not tolerated by the righteous path, and they joined forces to eradicate the evil cultivators who used the Heavenly Stone to rob others. In the melee, the only two celestial stones in the world disappeared without a trace. Qingyun Realm cultivator Yun Tiannan and junior brotherFengming accidentally discovered the existence of the Heavenly Stone, and in order to prevent it from being used by evil sects to practice the art of snatching houses and causing harm to the people, the two formed a barrier in the Qingyun Realm, where no outsiders were allowed to enter.
