In the future world, there are many magical drugs, such as: invisible medicines that make people invisible, flying medicines that can make people fly, medicines that can become bigger and smaller, and gas medicines...

Just say gas pills! Its shape is similar to that of ordinary medicine, but it has a very magical effect: the angry person ate it, and the anger in his heart subsided. People who are in a bad mood ate it, that is, "rainy weather." The worried person ate it, and the nervous heart became easier. The sad person ate it and his mood suddenly became clear. These are summed up, this is not the medicine that makes people happy! At school, some students are disobedient, and the teacher is of course very angry. As long as they eat the gas-suppressing drugs, the expression will become "smiley." At home, the child is ill, and the parents are very anxious. As long as they take the gas-supplement, the anxious heart relaxes. After the exam, the students who did not take the test must be very sad. When they go home, they must be embarrassed. They must be very scared. As long as they have taken the gas-supplement, their mood will be calm. They will be brave enough to face failure, study hard and strive for progress!
