Back to the Day I Picked up the Dragon King

The day before my sister and I went out to introduce seeds, I picked up the Dragon King. In order to repay his kindness, the Dragon King married me into the Dragon Palace. A hundred years later, I gave birth to a little golden dragon, and the Dragon King excitedly recognized him as the crown prince on the spot. Mother is more valuable than son, and I transformed from a carp spirit into the queen of the Lord of the Four Seas. And my sister, because her reproductive ability is too strong, has become a fertility machine in the clan. She was jealous of me and made me drink poisonous wine on the pretext of visiting relatives. When I opened my eyes again, my sister went straight to the place where the Dragon King was injured. I knew that she was also reborn. But she didn't know that marrying the Dragon King was easy. Giving birth to a dragon child is more difficult than ascending to heaven.
