Rowan's computer configuration is very ordinary, and it seems that he doesn't usually use it much, and he hasn't even done the most ordinary daily maintenance. Shang Ke first helped him fix the system vulnerabilities, and then downloaded several applicable tools on the Internet, such as multilingual programming software. If he could, he would like to change the system as well, but unfortunately this is not his computer, so he can only wait for the opportunity to build another computer by himself in the future.

"Coco, what are you doing?" Feng Jun leaned his head over and looked curiously at Shang Ke's fingers flying on the keyboard.

Shang Ke paused, turned his head to look at Feng Jun, and asked, "Do you want to learn?" ”

Feng Jun nodded vigorously. He thinks Shang Ke is very powerful, he seems to understand everything, he used to be E-language, and now he is a computer. On the other hand, he didn't know anything, and he didn't like the feeling of being left far behind.

"Okay." Shang Ke asked Feng Jun to sit down next to him, and then taught him to play with the computer from the simplest operation.

In this era, the computer penetration rate in country Z is less than 50%, far lower than that of Europe and the United States, and the technology is only in its infancy. Of course, this refers only to ordinary people, and there are not no hidden masters.

Feng Jun's learning ability is indeed very strong, Shang Ke just demonstrated it once, and he can quickly master it and draw inferences from one example.

The morning passed happily in the process of teaching and learning between the two.

The lunch was brought by the officer who was in charge of protecting them, and when the officer left, Shang Ke had an extra mobile phone in his hand.

Feng Jun looked at him in amazement: "You actually stole ......"

"Shh Shang Ke motioned for him not to make a sound, then took out the mobile phone card from the mobile phone, and checked whether the mobile phone was equipped with any Trojan horse or other monitoring software, and finally safely hid it in a vase, and the mobile phone card was thrown into the toilet and flushed away.

"Coco, what do you want to do?" Feng Jun asked.

"I need my phone to do something, and I hope the officer doesn't mind." Shang Ke looked out the door with an apologetic expression. When you have money later, you can compensate the police officer.

Rowan stuffed some money into him, but the money couldn't afford to buy a mobile phone, and he didn't want Rowan to know that he had a mobile phone, so he had to make this decision. If you have a mobile phone, you can use the money in your hand to buy a mobile phone card.

Feng Jun looked at him speechlessly, even if he stole his mobile phone, it was a police officer's mobile phone that he stole!

"Junjun, you'll cover for me later." Although they are currently under protection, their personal freedom is not greatly restricted, and as long as they are accompanied by a police officer, they can still move around.

Shang Ke and Feng Jun walked into a small shopping mall under the leadership of the police officer, and Feng Jun received Shang Ke's signal to help him divert the officer's attention.

Shang Ke quickly bought a mobile phone card, and then ran back before the police officer found out, which took only two or three minutes.

A few more people walked around, bought some snacks and books, and went back.

When he got home, Shang Ke took his phone out of the vase, put on the SIM card, and then went into the study, turned on the computer and started programming. He wrote a viral Trojan horse called "Jumping Worm", which is not only highly stealthy, but also capable of cross-infection.

When he was in the Hundred Refining Space, he relied on his extraordinary memory to memorize all the source code, so it is very easy to write now.

Shang Ke's expression was focused, and he didn't notice that Feng Jun had been standing next to him and watching quietly, a string of code programs flashed quickly in his pupils, as if a wonderful world had unfolded.

After three or four hours, Shang Ke finally finished writing the jumping worm, but he didn't stop and began to write the anti-surveillance firewall again.

But Shang Ke had only finished less than a tenth of the time, and Rowan hurried back.

Shang Ke hurriedly hid all the things on the computer, looked up and saw Luo Wen's stern expression, and couldn't help asking, "Detective Luo Wen, what's wrong with you?" ”

Rowan breathed a sigh of relief and replied, "Jason's mobile phone couldn't get through just now, I thought something had happened to you." ”

Jason was the police officer in charge of protecting them, and he was the one who stole the phone.

Shang Ke said without changing his face: "If the mobile phone can't get through, you can also call the landline at home." ”

Rowan was silent for a moment and replied with two words: "Forget." ”

Shang Ke was speechless at first, and then he was also a little moved. If I wasn't worried about them, I wouldn't be in such a hurry.

"I'll take you to the Children's Educational Activity Center tomorrow." "The regulatory system and the protections are very good, and you can be there during the day." ”

Shang Ke and Feng Jun naturally had no opinion.

In the evening, he went into the study again and spent five or six hours writing the anti-surveillance firewall. During this period, Rowan came to watch a few times, and saw two children playing games, so he casually told him "Don't play for too long" and left it alone.

Shang Ke put the firewall and jumping bugs into his mobile phone, and tried to run it without problems, so he showed a satisfied smile.

The next day, Rowan drove the two children to the puzzle activity center, in the car, Shang Ke quietly took out his mobile phone, clicked on the jumping worm, only to see the words "jumping" displayed on the screen, and ten seconds later, "jumping successfully".

Shang Ke successfully sent the jumping worm virus into Rowan's mobile phone. From now on, he can monitor every phone call, every text message, every email from Rowan. The most powerful thing is that he can also use Rowan's mobile phone as a springboard to infect all mobile phones and computers within fifteen meters of him, provided that the other party has Bluetooth or the Internet turned on and does not have a particularly powerful anti-surveillance program.

Luo Wen led Shang Ke and Feng Jun into the activity center, and a female teacher immediately came to receive them. Rowan had already greeted the person in charge of the place before, so the teacher didn't have a particularly surprised expression when he saw the two children.

Shang Ke and Feng Jun were taken to a small class, where more than a dozen children were playing, the youngest was about six years old, and the oldest was no more than ten years old.

Rowan was very satisfied with the environment here, and after a circle, he left, leaving only one JC to guard outside.

The teacher who takes care of them is called "Julie", who first introduces the two of them to the other children, then takes them to a cartoon-shaped table and chair and brings them a lot of toys.

Shang Ke scanned it, mainly there are Rubik's Cube, Nine Links, Puzzles, Hanoi Towers, Building Blocks, Graphic Cards and Drawing Tools, etc., all of which are some educational toys.

Teacher Julie probably wants to see their interests and preferences, and then guide and cultivate them in a targeted manner.

Shang Ke was not interested in children's entertainment, but Feng Jun was quite curious.

He picked up each one and looked at it, but ignored the Nine Rings. Finally, he pointed to the Tower of Hanoi and asked Shang Ke: "Coco, how do you play this?" ”

The Tower of Hanoi is the kind of toy used to test the intelligence of the orangutans in Rise of the Planet of the Apes, consisting of three wooden poles marked A, B, and C, with multiple perforated discs on the poles, which are smaller in size from bottom to top. Follow the rules and move the disc back and forth until you end up on the same wooden pole and see how many times you need to move it.

Anyone who has ever studied computer science should have done exercises similar to the Tower of Hanoi, and the recursive algorithm of the Tower of Hanoi is one of the preliminary algorithms of the C language.

Shang Ke took the Tower of Hanoi, picked up the disc and began to move, and within a minute, in different sequences, he successfully moved six times.

Feng Jun couldn't take his eyes off it, and Teacher Julie next to him also showed surprise.

Shang Ke handed the Tower of Hanoi to Feng Jun. Feng Jun first remembered that he had completed the steps that were acceptable, and then began to experiment with different ways of moving. In just ten minutes, he figured out some rules.

Shang Ke suddenly felt that Feng Jun was a computer talent. The Tower of Hanoi algorithm is actually not difficult, but the deduction process is very painful, and it is impossible to complete without clear logical thinking.

Teacher Julie watched them fiddle with the Tower of Hanoi and was thrilled: these two are no ordinary children!

After Teacher Julie left, Shang Ke picked up the Nine Rings and asked, "Don't like this?" ”

Feng Jun glanced at it and said lightly: "I'm tired of playing with this before." ”

Shang Ke: "...... "Could it be that this guy is still a genius?"

Taking advantage of the time to go to the bathroom, Shang Ke sat on the toilet, turned on his mobile phone, and plugged in his headphones. Rowan's call log was immediately displayed on the screen, and he ignored these, instead activating the jumping bug, asking it to search Rowan's network, and then follow the network around.

One life is two, two is three, and three is everything.

The ultimate goal of Shang Ke is the internal server and electronic surveillance of the police department.

Although jumping insects can theoretically spread indefinitely, they are limited to the backwardness of the mobile phone system, and the monitoring can only be carried out one-to-one, not at the same time. And the jumping insects that spread out can't be eliminated unless he can hack them into these computers one by one.

Shang Ke is not worried that the jumping insects will be discovered, at least for four years. It attaches to other programs, can camouflage itself, and as long as the main program is not activated, it is basically invisible and takes up very little space.

With today's technology, unless it is a targeted search and killing, it will not be possible to detect its existence at all.

If he had his own computer, it would have been much easier to spread the jumping bugs, but unfortunately for the time being, he could only do it step by step.

In the next few days, Rowan simply became a mobile source of infection, but everywhere he passed and the people he came into contact with, they would leave the mark of the jumping worm.

The hard work paid off, and by chance, Shang Ke captured an image of a member of the gang through guò surveillance video, and then followed this clue to find a den.

"I think there may be some secrets hidden in those two kids." Angeli said to Rowan, "Otherwise, there is no need for those people to bite the two children and find the puzzle activity center." Although the identity of the other party is not yet certain, what else is worth paying attention to there besides those two children? ”

"I feel the same way." Another officer, Banter, agreed, "Rowan, you have the most contact with those two children, do you have any thoughts?" ”

Rowan shook his head and said, "Not for the time being, I will continue to communicate with them and see if I can get any clues." Now, let's get back to the case at hand......"

Just then, a technician suddenly reported, "Come and see, I've received a strange email. ”

Several people hurriedly ran over, and there was an audio text and an address in the mail.

Click on the audio, and the content of a man's call is playing, which seems to be checking the delivery location.

Luo Wen's expression froze, and he asked, "Can you find out the source of the email?" ”

The technician said helplessly: "No way. ”

"Let's go." Rowan made a note of the address in the email and led the team to attack quickly.

Whether it's true or not, they have to verify it.

Fortunately, the intelligence is true, and they used it to end up a criminal den.

However, they did not connect this small group with the Tabimu they had been tracking down, that is, the group that was stalking Shang Ke and Feng Jun at this moment.

In the following two months, the police received three more similar pieces of information, but the source was never found.

Tabimu was raided and the internal situation became tense, and he began to shrink his power.

The crisis between Shang Ke and Feng Jun was temporarily lifted, but Rowan and the others completely got involved with that gang. No one knew that this qiē turned out to be a "child" behind the scenes.

A year later, Shang Ke and Feng Jun were sent to foster care with a monthly subsidy of 500$. Although Rowan was very reluctant, he also knew that with his family profession, he was not qualified to adopt them.

This year, Shang Ke and Feng Jun officially became primary school students at Fran Primary School, and had their own E literary names - "Buno Bru" and "Ian Ian".
