Right and Wrong, Fairies and Demons

In the third year of Tianfeng, the new Demon King and the new Immortal Lord gave birth to Peiling. In order to prevent others from discovering Peiling's life experience, they said that Peiling was picked up. Twenty thousand years later, because he was not good at academics in the fairy world, he was forced to go down to earth to undergo calamity. After arriving in the mortal world, he was rescued by the demons. In order to repay his kindness, Peiling went to study in the demons. Three hundred years later, Peiling mastered magic and immortality, and went to the fairy world to avenge his hatred. After all the immortals were killed, he realized that the current Demon King and the Immortal Lord were his parents. So he was heartbroken and used his own magic to kill himself. When the Demon King learned about it, he used magic to turn the three of them into mortals and lived a happy life ever since.
