What's the Point of Falling in Love and Cultivating Immortality?

Legend has it that in order to quell the war between the Demon Realm and the God Realm and avoid killing, they personally sent the princess of the Demon Realm to marry the emperor of the God Realm! On the wedding day, the glow was brilliant, and the golden light of merit spread throughout the three realms! All the gods and demons were amazed and said, this is a great marriage! As everyone knows, this is done on purpose. After getting married, the emperor and the princess lived in seclusion, and there was no trace of them for thousands of years. Little did they know that the children they gave birth to would be so lively! It might look like this: "Ouch! Ouch! Your Highness! Please don't pluck out my old man's beard. There are not many of them left." A white-haired old man in a white robe was talking bitterly to a child, and his beard was in her hand. "Hey, your highness, those are my newly made clothes, there must be no stains!" A collapsed fairy chased a child out and shouted loudly. It's also possible: "Please eat bee pupae!" The child with a smiling face threw a huge beehive at it, and the god caught it blankly. When he looked up again, the child was gone. Looking down at the hive, I saw a swarm of bees flying out! "Help!"
