Jun Xuan accepted the prince of the Emperor of Heaven as his disciple. This man was born to be easily attacked by demons. To ensure that he grew up safely, the Queen of Heaven gave the child to the god Jun Xuan of the Immortal Formation Island, the most spiritual place in the world, to raise him. The prince changed his name to Yun You and worshiped her as a disciple. Under Jun Xuan's careful teachings, he washed away the sinister spirit and learned the immortal method.
The good times did not last long, Jun Xuan's magic power was greatly reduced during the calamity, the demonic energy eroded the fairy island, and the human world was in chaos. In order to protect the world's common people, Jun Xuan's cultivation was wiped out. When Yunyou was in despair, accompanied by Qilin, he resolutely took up the responsibility of guarding the Immortal Island and the people of the world. He was afraid that he could not guard it alone, so he trained eleven powerful immortals over the millennium to protect it together to ensure that nothing would go wrong. However, the demon king came to the world to bring harm to the people. Yunyou died together with the demon king in that fairy-demon war. The person who inherited his unicorn mount was the youngest female disciple, known as the unicorn war god.
A hundred years later, a new demon king appears, and a war between immortals and demons begins again...
Intention: You become an immortal and I want to become an immortal. You become a devil and I want to become a devil. Master and disciple protect each other.
