Yundi was struck to death by lightning because she was trying to eat a fish. When she woke up, she learned that the dead fish was a koi fairy, so she wanted to protect the dead fish and travel through three thousand worlds to experience the disaster again. Yundi: "It was the pot of boiling water that stewed you, it has nothing to do with me!" Dead Fish: "No, no, no, since you stewed me, you must be responsible for eating me clean!"
