Detective Training Manual

Please remember, never dig out unsolved puzzles.

Because you will never know how much people paid to cover it up.

Under the surface of false calm, most of the truth is cruel…

Okay, let me make it clearer.

If one day, you see a book falling on the ground on your way from get off work, and you are restrained by your curiosity, don’t touch it.

……

Unfortunately, the original Zhou Yan did not realize this.

So he picked up the book.

That book has a very awkward name-“The Detective Practice Manual”

As for the author… it’s called Fat Gua.
