There is a kind of creature that likes to laugh when it is happy and laughs when it is angry; it likes to laugh when it plots against others and it also likes to laugh when it is plotted by others. Gu Yan called this strange creature Xia Rong.
Therefore, Xia Rong may not be in a good mood when he laughs. He is most likely angry or plotting against you. Likewise, this law also applies in reverse.

To sum up, this is a story about a sinister evildoer who overwhelms a natural idiot. The writing is harmless, please feel free to eat it (⊙v⊙)
