One day, when the third princess heard that the black water dragon king had gone to the sky again, she hurriedly ran to the black water harem and saw the black water lady and said, "Mom, it's not good. The sable bit a cave long in the treasure chest. It's bad if it's damaged!" The black water Niang listens, takes out a small girl waist gourd from the pocket, reads: "the gourd opens, the gourd opens, spits out the treasure chest key!" Read three times in a row, only to see a golden light, flying out of the gourd a key. The Niang Niang hurriedly handed the three princesses and said: "this is the key to the treasure chest. Go and have a look. Don't miss it!" The princess said "yes", turned around and ran out.
The third princess took the key to the treasure chest, opened the treasure chest, took out the treasure jacket and sword, found the second prince and the sable, and rushed out together. Some fish, turtles, shrimps and crabs in the pond also ran out of the mouth of the three rivers together. Since then, many fish and shrimps have grown in the three rivers. When the third princess and the second prince arrived in the world, they hurriedly took out the longevity flower seeds from their arms and spread them in the wind. In a blink of an eye, they opened the red longevity flower everywhere.
The third princess and the second prince spread the longevity flower to the world. From then on, the world also had the longevity flower. All the diseases in the world were cured by the longevity flower, and the world was full of laughter.
