After I married off my disabled dragon prince, the infertile Dragon Crown Prince went mad with regret
A thousand years ago, while the Dragon King was traveling with his daughter, a destitute demon clan member carrying a young child came to propose a marriage alliance.
The Dragon King flew into a rage, hurled insults at the lowly, impoverished demon, and cursed him to die without descendants and never be reborn.
From then on, every dragon prince in the Dragon King's line was afflicted by the curse.
On reaching adulthood, they would lose their dragon tails and magical powers, reverting to young snakes.
No matter how hard they cultivated, they could never increase their magical power by even the slightest amount.
Worse still, even adult dragon princes would lose the ability to have descendants entirely.
The curse could only be lifted by joining with a female snake demon raised on the banks of the Forgotten River and blessed with an exceptionally fertile constitution.
For three hundred years, my younger sister and I were the only two snake women raised on the banks of the Forgotten River, both blessed with exceptionally fertile bodies.
As long as they touched us, even the most useless male could soar through the skies like a dragon, roam the world, and father descendants.
