It comes from a love affair between fish and water. In a catastrophe, the immortal body of a heavenly king perished, but she ascended to a high position. She went down to earth to look for him and spent billions of eons between him and the mortal world. She fed the soul-gathering demon lantern with divine blood to summon his soul, killed for him, and changed his heavenly name. However, on the day he returned to his throne, he mistakenly regarded her as a little mermaid demon. When she endured the tribulation of eighteen karma obstacles from the sky, she was given the pain of cramps and soul peeling, and the torture of six heavenly thunders. He was dressed in a black robe as clear as water, standing high on the Immortal Platform, with a pair of waveless eyes that were cold and unfeeling. He asked in a deep voice, do you regret it or not? She smiled bitterly and replied, "Even if it hurts me, I can still bear it."
