Xu Yi'an, an ordinary college student, obtained a "Dictionary of All Worlds" from another world due to an accident. This dictionary not only allows him to understand all the world's languages, but also has a perverted ability - when he speaks "correct" modern slang, it will trigger corresponding supernatural effects. For example, saying "lying flat" will give you absolute defense, saying "rolling up" will make enemies kill each other, and saying "rolling in" will cause the space to collapse.
