Demon Lord Wants to Settle Down

Demon Lord Xi Nian has dominated the demon world for three hundred years, and he has had a smooth journey, fearing neither heaven nor earth. Until the child picked up and raised reaches the age of going to school. The child is young and has many ideas. He dislikes the educational resources in the devil world and insists on going to school in the fairy world. But if you want to go to school in the fairy world, you have to settle down in the fairy world. Housing in the school district is easy to solve, but settling in has become a big problem. The laws of the immortal world stipulate that demon cultivators are not allowed to settle alone, nor are immortals and demons allowed to form Taoist couples. In other words, if Xi Nian wanted to settle down, he had to find a mortal who could cultivate immortality, form a Taoist couple with that mortal, and then settle down in the immortal world with him. Xi Nian asked the chief marriage master of the demon world to guide him and find a person in the mortal world who was most likely to achieve enlightenment. After the marriage was formed, Xi Nian came to the mortal world, and happened to meet the industrious mortal who was knocked unconscious by a few punches from his fellow disciples. Xi Nian: ... You told me how many years it will take for him to become an immortal? Marriage Master: Uh... - All the immortals know that Yu Qing, the leader of the immortals, and his childhood sweethearts, the demon king in the demon world, turned against each other when they grew up. One became an immortal and the other a demon, and they have been incompatible ever since. But no one knows that the Immortal Head and the Demon Lord once had a vigorous love affair. Three hundred years ago, the boundary between immortals and demons was in turmoil. In order to maintain peace between the two realms, Yu Qing lost half his life's cultivation, and Xi Nian lost his memory of the past. After three hundred years, the two never saw each other again. Yu Qing originally thought that the fate between the two of them was over, so he sealed his love and cut off his feelings. Until the immortal realm was in turmoil, he came to the mortal world to investigate the matter thoroughly and chose a mortal who had just died to possess him. When I opened my eyes, the face I had missed for three hundred years was very close at hand. And invited him to get married. *Given to my precious Momo's Gu Dan.
