This book, in fact, is a textbook, I am not telling a story, what I want to give you is not some fanciful and unrealistic techniques.

Whether it's watching a movie or reading a novel, sometimes I feel very cool, and the people in it are very powerful, but if we change it, is it okay, it's rare to have one out of 10,000 people.

We are not those omnipotent hackers, not those martial arts knights, we only have the title of the public, make a little money, live a life, and the most capable ability may only be cooking.

So I've always wanted to give you something real, these things, when you are cornered, or when you are too pressed to hold your head up, give you a little confidence, give you a little strength to resist.

This power, called dark ink, occasionally saw Mr. Gao's masterpiece, and felt very admired, he pointed out a road that could not see the light, but it was very practical, wasn't it?

We are the public, but not sheep, willing to be honest, but we will never let people eat meat.

What I give you doesn't need to be anything special, as long as you are willing to read this book to the end, then you are fully qualified to have this thing.

I'm not the first or last book on deception, a book in the genre of a thousand arts, but I want to ask everyone, don't you think it's an exaggeration, the people in it are either hackers, or strong in martial arts, or *all kinds of thaumaturgy.

It looks beautiful, it's like this, they are masters, they can beat a strong man three meters away with one palm, they know the mechanism, they know the secret arts, and they know all the mysterious skills that we don't understand.

But what we want, or what I want, is not these, I can occasionally hit someone similar to me, at most I will put a Trojan horse, I often get lost while driving in Beijing, I am a mortal, I can only read.

So my book must be true, you must have read it, you can learn it, and you can definitely use it after you learn it.

A friend also once told me that if you don't write so mysterious, not YY, and don't write the protagonist invincible, then hit the street.

I don't want to hit the streets, but I don't want to write like that, the main theme of this book is practical deception, deception and dark ink, which is what I want to bring to you.

Without those miraculous things, this book may be a little light, hundreds of thousands of words to read, maybe it will be very disappointing, but please read Mr. Gao's dark ink.

I want to give everyone strength, give everyone the strength to protect themselves, many times, in front of us, it seems that there are many choices, but the truth is always the same, we don't have a choice at all.

I don't like this kind of powerless life, so I chase power, and after I get this power, I like more people to stand up like me, become stronger, and protect everything they have.

Finally, thank you all for your support.
