Hua Luofan, who was about to graduate from college, was taking a walk by the river. Out of kindness, the cute Hua Luofan spent 500 yuan to buy a jade pendant belonging to an old man on crutches on the roadside. As a result, the next second he was pushed into the river by the old man. When he woke up, he found that he had turned into a koi and was placed in a fish tank.
