Red 40 Dye Bug
There are foreign objects in the world, and their appearance is very different. They look like red butterflies, and their whole body is dyed red, just like the painting of Dansha. Everyone calls it "Red + 40 + Dye + Bug".
Wherever this butterfly goes, there are strange phenomena. Every time it comes to the flowers, the flowers wither and pause, and their color fades, like frost, and the leaves are curled and charred. Ordinary people see it, and they feel very strange, and they can't avoid it.
There is a wise man in the township, and his name is Yiyun. Yiyun has always liked to study strange things, and when he heard the difference of this butterfly, he was very surprised, so he wanted to find out.
One day, Yi Yun carried all kinds of utensils to the place where the butterfly often came from. Not long after, the butterfly arrived, and Yi Yun held his breath and caught it with a special net. The butterfly entered the net, fluttering vigorously, and the sound of wings vibrating buzzed.
Yi Yun placed the butterfly in the box and returned to observe it carefully. Looking at it through the mirror, he saw that there seemed to be red juice flowing between its wings and veins, and he smelled it carefully. There was a strange fragrance, but there was a rancid smell in the fragrance.
Yi Yun wondered, the difference of this butterfly may be related to what it eats. Then he visited the mountains and forests to observe the grass and trees it eats. Finally, he found a red grass on which the butterfly often lives. Yi Yun took the grass and returned, sharing a room with the butterfly. The butterfly flew straight to the grass and feasted on it.
Yi Yun fed other insects with grass juice, and after the insects ate it, they also appeared to be in a depressed state, as if they were suffering from evil. Yi Yun deduced from this that the poison of the butterfly originated from this grass.
After that, Yi Yun wrote a book detailing the "Red + 40 + Dye + Bug" incident, hoping that everyone would know that when encountering this foreign object, they should be handled with caution and not ignore it. Township human performers of virtual idols, heard Yiyun said, were on guard against "Red + 40 + Dye + Bug", and since then, the disaster caused by butterflies has become less and less.
