Hearing the system's words, Zhou An thought for a moment and asked again: "What is the approximate level of the skills exchanged?"

Although, Zhou An is very confident in the police system. Pen & Fun & Pavilion www.biquge.info

But these skill books are all beginners, beginners, or something, as if they are all basic things.

It's not that Zhou An is unwilling to learn the basics, it's just that he is now one hundred and twenty-one chivalrous values.

It would be a tragedy if you redeem a skill but can't solve the problem at hand.

"Sorry, it's forbidden to reveal until the host has not redeemed. ”

The system replied.

"That's enough. ”

Zhou An's face darkened, he thought for a while, gritted his teeth, and said, "Exchange for a beginner computer primer." ”

Now, the most directly related to Yu Zhongxian is his account on the dark web.

If the evidence of his transaction can be obtained through hacking technology, it is definitely extremely powerful evidence.

Zhou An can only give it a try.

"Congratulations to the host, the exchange is successful, and I have obtained the elementary computer introductory skills book, do you want to learn directly?"

"Yes!"

Moment.

Zhou An is feeling, an invisible flow of information, poured into his mind.

It was as if I had been empowered, and I had a lot of knowledge about the computer field in my mind.

After a while, Zhou An came back to his senses and grinned.

It seems that I am completely overly worried.

In the preface to the book, it is written that the term "beginner" is based on the state of science and technology in 2998.

This first volume mainly talks about the technology of the PC era and the mobile Internet era, and represents the highest level of technology in this era.

As for the next volume, it represents the highest level of technology in the VR era and the era of artificial intelligence, and it takes two hundred chivalrous points to redeem.

This result made Zhou An overjoyed.

In this case, it is definitely not a problem to be a black web.

After redeeming this skill book, there are still blackjack chivalrous points left.

Within the blue nine-square grid, the surrounding eight turned gray again, and only the small question mark in the middle was still lit.

There are also two entries to the draw.

However, Zhou An didn't care about the lottery at this time, he couldn't wait to test the power of hacking technology.

I vaguely remember that there was an Internet café on the way over.

Zhou An hurried over.

"Network management, open a machine, and ask for a private room. ”

Quickly turned on the computer and put his hands on the keyboard, Zhou An took a deep breath and tentatively entered the first line of code.

“hello，world。 ”

After saying hello to the computer world, Zhou An embarked on his first programming journey.

Lines and lines of characters are quickly presented in his hands.

Zhou An decided to warm up first.

A few minutes later.

Outside the box door, there was a flurry of curses and shouts.

"Webmaster, come on, my hero is down!"

"What a rotten Internet café!"

"Network administrator, come on, you're going to die!"

……

Chickens and dogs jumped outside, and Zhou An smiled proudly.

The warm-up was successful!

Zhou An sat in front of the computer, and there was a subtle feeling in his heart, it seemed that as long as he wanted to do something, he would subconsciously give the operation steps in his mind.

He was in action again.

Target, Dark Web!

Zhou An first scanned the computer in the Internet café, plugged all the loopholes, ensured his safety, and then began to write small plug-ins for use.

Scanning software, remote control trojans, trace cleaning software, dynamic IP ......

These small pieces of software are weapons in the hands of hackers.

It is no exaggeration to say that the current Zhou An has just received a gift of technology nearly a thousand years later, and the weapon in his hand is definitely the sharpest.

Zhou An clearly remembered that the website where Yu Zhongxian bought the murder was called Demon Night.

About a few minutes later, Zhou An logged in to the server of this website with the account account that Wang Hongjun had confessed.

Through the previous transaction records, the buyer's account number was quickly found.

traced the past along the Internet, but Zhou An found an extremely painful situation.

The buyer's account has been cancelled!

The treacherous and cunning Yu Zhongxian!

This website has a very high degree of confidentiality information for buyers, and once it is logged out, all data is permanently deleted, and the background of the website will not be retained.

If you have to forcibly recover, with Zhou An's current technology, you can do it.

However, that has to deal with an astronomical amount of data, and ordinary computer and network traffic simply can't handle it.

With the current hardware level and processing speed on the earth, it will take at least half a month, and there can be no interruption in between.

This result silenced Zhou An.

After a moment's hesitation, he began to look for another way.

A few minutes later, Zhou An hacked into Yu Zhongxian's work computer.

Although the security factor of the police network is relatively high, in the eyes of Zhou An now, it is completely his own backyard.

It's just that after walking around, I didn't find anything except some system software and work data.

Yu Zhongxian has a strong sense of confidentiality, and he doesn't even have a personal QQ on his work computer.

Zhou An was not discouraged, and through the website of Xingyi Advertising Company, he invaded Wu Mei's work computer.

It took about an hour, again without finding any important points.

However, in Wu Mei's encrypted disk, I found her ambiguous chat history with another man, as well as some large-scale photos.

Zhou An is full of black lines.

These rich people really know how to play.

Copying these things down first and throwing them away in his mailbox, Zhou An unwillingly continued to test the computer at Yu Zhongxian's house.

From Wu Mei's computer, he found Yu Zhongxian's home address.

However, that computer did not turn on.

Zhou An had no choice.

Light a cigarette and smoke it.

After smoking two cigarettes in a row, a new idea came to Zhou An's mind.

With his hands crackling on the keyboard, he hacked into the system of the property registry after upgrading his tools again.

Under the name of Yu Zhongxian, there are a total of three houses.

One is located in Gangnam City, where he lives by himself.

One set is located in the city of Beijing, probably for investment, and was bought five years ago.

One set is located in Yalong City, and if nothing else, it should be for tourism.

According to the location of the three houses, Zhou An checked the network addresses respectively.

The houses in the capital and Yalong are probably empty, and there is no network at all!

Moreover, there are three houses, which doesn't mean much.

After all, Wu Mei is in business, and five years ago, people bought a house in the capital, which doesn't mean anything.

Boom!

Zhou An punched hard and slammed it on the table, feeling a little impatient.

Call......

Realizing that he had a problem with his mentality, Zhou An took a few deep breaths to calm himself down.

He decided to change his mind.

Suddenly, Zhou An's eyes lit up.

He thought of Zhang Shuting.

A large part of the reason why Yu Zhongxian went to such great lengths to murder Zhang Shuting was that Zhang Shuting seemed to have discovered some of his secrets and threatened him with this.

Zhang Shuting......

Zhou An changed the target, staring at the computer with his eyes dead, and his fingers were flying.

Outside, it was getting dark.
