The Darling Wife of the Koi King Wants to Throw Me into the Hualong Pond

I was originally a high-level red and white koi, but after giving up my vitality and golden elixir to save my son, I became a tarnished black koi. Later, my son became the legendary high-level red and white koi king, so I could rest assured in the deep palace to recuperate. Three hundred years later, my son's beloved wife, the little koi, regarded me as a lowly koi who seduced my son. You want to throw me into the Hualong Pond! Finally, he sent me to my son: "Koi King, look, I have eliminated the scourge of the Koi clan for you."
