Summer is coming, and here comes the blue fruit truck![1] What kinds of fruits does it have? 

Summer is a thriving season for all living things. Ripen on the branches, one by one the fruit fairies wake up from their sleep. Round and plump watermelons roll, turning into lively ladybugs, while mangos, golden with deep fragrance, stretch out and transform into flying shrikes. Suddenly, a waft of strange black and grey mist drifts by. It does not take roots in soil, nor does it sprout in water. Instead, it makes the land grey and sick in misery.
