In the middle of the night, a round of faint moon hanging high. On the chaotic graveyard in the southern suburbs of Z City, two black shadows are sneaking and digging. One of the shadows is a fat man. The fat man whispered while dig a hole, "Watch the dog, do we count, is it murder?" The thin man on the side did not breathe back: "Don't say it! We are just ordered to bury a dead person." Fat man: "Yes, but he seems to have not broken his breath, and his documents, he is a policeman, policeman?" "I said the third child, you TM dog shi, on the eyes, how much useless? Why can't this happen, Yang boss will never let us go, it is us who are buried back!" The thin man couldn't help but swear: "Who is this kid who is guilty, a police school student who just graduated from the district, actually has the courage to track the transaction of Yang boss?"
