The Lucky Carp Princess Wants to Throw Me into the Dragon Transformation Pool

I was once a high-grade red-and-white koi. After giving up my vital essence and golden core to save my son, I became a dull, black koi. Later, my son became the legendary king of the high-grade red-and-white koi, so I rested easy as I recovered in the depths of the palace. Three hundred years later, my son's spoiled little koi wife mistook me for a lowly koi trying to seduce him. She was going to throw me into the Dragon Transformation Pool! In the end, she even brought me before my son. “Koi King, look. I’ve rid the koi clan of this menace for you.”
