When the Demon Lord of the Demon Realm was going through tribulations in the human world, he befriended the Supreme Being of the Immortal Realm, the Jade Emperor, who had also gone through the tribulations in the human world. After the Demon Lord went through the tribulations, he returned to the Demon Realm and even beat her to death without admitting that she was a woman. However, the Jade Emperor, who felt good about it, returned to the Heaven Realm after completing the training, but he did not recognize the human world. The woman never forgets her, and it is unforgettable every time she thinks about it. By an unexpected coincidence, the two of them exchanged bodies, and the Jade Emperor knew that the woman he thought about day and night was the Demon Lord. Through the body of the Demon Lord, he discovered that the Demon Lord in the Demon Realm is so rich, and the Demon World is so rich. The Demon Lord who exchanged his body was in the immortal world, looking at the exquisite and majestic Immortal Palace and how poor he was, and then he realized how poor the Jade Emperor was. When the Demon Lord used the body of the Jade Emperor, he looked at all the immortal officials and maids in the dynasty, wearing tattered robes. When he was wearing court clothes, he asked weakly: "My dear! Why don't you wear good court clothes?" All the immortal officials replied sadly and angrily: "Your Majesty, you have owed us three thousand years of unpaid wages. I still have a family of young and old who have to eat to feed me!" She asked again: "What about the treasury of the Immortal Kingdom?" "
An immortal official dressed in rags like a beggar stood up and replied: "Your Majesty, you know that since you succeeded to the throne, the treasury has nothing but walls! ". So, he pretended to be calm and said: "With me, everything will be fine." But in his heart, he was breaking down and thinking, when can I change my body back? But the Jade Emperor said: "I will change it when you give birth to a child! ".
