Chapter 35: Let Me Protect You (III)
Rowan’s computer configurations were very ordinary, and it appeared that he did not use it often, because even the most common firewall wasn’t set up. Shang Ke first helped him to fix some system holes, before going online to download some applications, like multi-language programming software. If he could, he really wanted to change the computer’s entire system, but unfortunately, it wasn’t his laptop. He could only wait until he got the chance to assemble and install his own computer.
“Keke, what are you doing?” Feng Juan moved his head closer, curiously watching Shang Ke’s speedily typing fingers.
Shang Ke paused in his actions, then turned his head and asked, “Do you want to learn?”
Feng Juan nodded his head with all his might. He felt that Shang Ke was very amazing and seemed to know everything. Before it was English, and now it was computers. Compared to Shang Ke, he didn’t know anything. He really didn’t like feeling being so far behind him.
“Alright.” Shang Ke had Feng Juan sit near him, and began to teach him how to use a computer from the very basics.
In this period, only about fifty percent of China’s total population had a computer, which was far lower than Western countries. China’s technology was also at the primary stage. However, it wasn’t like there weren’t any experts hidden among the masses.
Feng Juan was able to learn very quickly. Shang Ke only had to demonstrate once before he could grasp the skill, and even deduce further knowledge.
In such a manner, their morning cheerfully slipped by as one taught and one learned.
One of the guards in charge of protecting them delivered lunch. When the guard left, a cell phone laid in Shang Ke’s palm.
Feng Juan looked at him in admiration. “You actually stole…”
“Sh!” Shang Ke motioned for him to be quiet, before taking the sim card out from the cell phone. He then checked the phone to be sure that there wasn’t any kind of trojan horse or other monitoring software before hiding it in a flower vase with relief. The phone card was flushed down the toilet.
“Keke, what are you trying to do?”
“I need the cell phone to do some things. I hope that guard won’t mind.” Shang Ke looked at the door with an apologetic expression. He will compensate that guard once he has money.
Rowan had actually given them some money, but the amount wasn’t enough to afford a cell phone. He also didn’t want to let Rowan know that he had one, so he could only steal it. Now that he had a cell phone, he could use their money to buy a new sim card.
Feng Juan stared at him silently. It was fine if he stole a cell phone, but the one he stole from was a guard!
“Juan Juan, you help cover for me.” Although they were currently being protected, they still had their freedom and weren’t too restricted, so they could go wander around nearby.
Shang Ke and Feng Juan were led by a police officer into a shopping center, and Feng Juan got Shang Ke’s hint, helping him to distract the police officer.
Shang Ke quickly bought a good sim card and returned before the officer saw. Only two to three minutes had passed.
After they wandered around and bought some snacks and books, they returned home.
Returning to the house, Shang Ke fished out the phone from the flower vase and inserted the phone card before squeezing into the study. He switched on the computer and began to code. It was a version of the virus ‘Trojan Horse’ called ‘Jumping Virus,’ and was not only difficult to detect, but could also spread.
He had relied on his outstanding memory to remember the entire source code in the Hundred Training Space, so he could write it very easily now.
Shang Ke concentrated on his task and didn’t notice Feng Juan standing quietly beside him as strings of code formed and flashed by his eyes. It was like an amazing world was unfolding before him.
After three or four hours, Shang Ke finally finished coding the Jumping Virus, but he did not stop and began to create a monitoring firewall.
However, Shang Ke had not even completed one-tenth of it before Rowan rushed home.
Shang Ke immediately hid what he was working on, and raised his head to see Rowan with a serious expression. He asked, “Detective Rowan, what’s wrong?”
Rowan heaved a sigh of relief and replied, “I couldn’t get through to Jason’s phone for a while, so I thought that something may have happened.”
Jason was the officer who was in charge of protecting them, and also the one he had stolen the cell phone from.
Shang Ke spoke without a change in his expression, “If you can’t get to him through his cell phone, you could have called the line at home.”
Rowan fell silent for a moment before speaking, “I forgot.”
Shang Ke was first speechless, then a bit moved. If Rowan wasn’t worried for them, he wouldn’t have been so anxious.
“I will send you guys to the Children’s Activity Center tomorrow,” Rowan said, “The administration and protective measures there are both pretty good. You guys can freely move around there during the day.”
Shang Ke and Feng Juan naturally did not have any objections.
At night, they once again sat in the study and used another five to six hours to complete the monitoring firewall. During that time, Rowan popped over several times, but merely left a warning when he saw the two children playing games, “Don’t play too late,” and did not bother them.
Shang Ke installed the firewall and Jumping Virus onto his own phone. After trying it and seeing no bugs, a satisfied smile formed on his face.
The next day, Rowan drove the two children to the Children’s Activity Center. On the way there, Shang Ke quietly took out his cell phone and tapped on the Jumping Virus. The words “Currently Jumping” showed on the screen, turning into “Jumping Complete” ten seconds later.
Shang Ke successfully sent the Jumping Virus into Rowan’s phone. From now on, he could monitor every call Rowan makes, and every text message and email he sends. The virus’ strongest point was that he could even use Rowan’s cell phone as a springboard to infect all cell phones and computers within five meters of it. However, this was with the prerequisite that they had bluetooth enabled and did not have some kind of large company’s monitoring program.
Rowan led Shang Ke and Feng Juan to the Activity Center, where a female teacher immediately came forward to greet them. Rowan had already given them a heads up before he came, so this teacher did not have a particularly surprised expression at seeing the two children.
Shang Ke and Feng Juan were led to a small class, where there were more than a dozen kids playing in there. The youngest was around six, while the oldest was only ten.
Rowan was very satisfied with the environment. He left after making looking around, leaving behind a single police to stand guard outside.
The teacher in charge of taking care of them was named “Julie.” She first introduced them to the other children, before leading them to a cartoon-style table and bringing them a pile of toys.
Shang Ke swept his gaze across all of them. They were all educational toys: a Rubik’s Cube, nine chain, jigsaw puzzle, Tower of Hanoi, toy building blocks, coloring pages and drawing equipment, and so on.
Ms. Julie probably wanted to see their preferences, and then nurture them in that direction.
Shang Ke did not have much interest in children’s entertainment, but Feng Juan was rather curious.
He picked up every single one to take a closer look, and the only one he didn’t understand was the nine chain. In the end, he pointed at the Tower of Hanoi and asked Shang Ke, “Keke, how do you play with this one?”
The Tower of Hanoi was a toy used to test orangutans’ intelligence. It was composed of three wooden poles marked A, B, and C, respectively, with round disks on A that decrease in size going up the pole. According to rules, you have to move the disks around the poles until they were all in ascending order on a new pole. Its purpose was to see how many times you needed to move the disks before they were all shifted over.
Those who have learned topics related to computers have all done exercises similar to the Tower of Hanoi. The Tower of Hanoi’s recursion calculation was one of the primary algorithms of C.
Shang Ke took the Tower of Hanoi and moved a disk. In a minute, he moved the disks six times into different arrangements.
Feng Juan watched attentively, while Ms. Julie was also very amazed.
Shang Ke gave it back to Feng Juan. Feng Juan thought back to how Shang Ke did it, and first used the same method. Then, he tried to move the disks in different ways. After only a dozen minutes, he had actually figured out some rules.
Shang Ke suddenly felt that this guy actually had an affinity for learning computer programming. The Tower of Hanoi algorithm wasn’t difficult, but deducing the process was a pain. It was impossible to do without a clear, logical thought process.
Ms. Julie watched them play around the with the Tower of Hanoi and was very moved, thinking to herself, These two children were extraordinary!
After Ms. Julie left, Shang Ke picked up the nine chain and asked, “You don’t like this?”
Feng Juan glanced at it and blandly said, “I got bored of playing with that a long time ago.”
Shang Ke: “……” Could it be that this guy was actually a genius?
Using his limited time in the bathroom, Shang Ke sat on the toilet and turned on his cell phone, before plugging in his headphones. Rowan’s call history was displayed on the screen. However, Shang Ke did not pay attention to it, but rather, he activated the Jumping Virus and had it search for Rowan’s internet, following the connection and jumping all over the place.
One turned to two, two turned to three, and three increased endlessly.
Shang Ke’s final goal was the police department’s internal server and electronic monitors.
Although the Jumping Virus could spread without end in theory, it was limited by the cell phone’s lag. He could only monitor one device at a time,e. Additionally, Shang Ke couldn’t clear away the Jumping Virus’ he had spread, unless he hacked into each and every one of the infected computers.
Shang Ke was not worried that someone would detect the Jumping Virus, or at least he didn’t need to worry for the next four years. He designed it to be disguised, and would not activate unless the owner triggers it. It was pretty much invisible, and only used a very small amount of space.
With the technology of today, unless someone specialized in detecting viruses, they simply would not be able to discover its existence.
If he had his own computer, then it would be much easier to send out the Jumping Virus. Unfortunately, he could only do it one step at a time.
In the following days, Rowan became Shang Ke’s moving source of infection. A trace of the Jumping Virus was left behind in every place he passed through and with everyone he contacted..
Effort will not disappoint, and Shang Ke incidentally caught a gang member with the monitoring system. He followed their trail and found the den.
“I think those two children might still have some kind of hidden secret,” Angelie said to Rowan, “Otherwise, that group wouldn’t latch onto those two so tightly and refuse to let them go, actually finding their way to the activity center. Although we still aren’t sure of the children’s’ identities, besides those two, what else is there for the gang to pay attention to?”
“I also feel the same,” another officer expressed his agreement, “Rowan, what is your opinion on the two, since you have had the most contact with them?”
Rowan shook his head and replied, “There’s nothing for now, but I will keep interacting with them and see if I can’t get some clues. In the meantime, let’s go back to the case at hand…”
Right at this moment, a technician suddenly reported, “Come and take a look at this. I got a strange email.”
A few people quickly rushed in. The email contained an audio file and an address.
They played the audio, which recorded a conversation of a man who seemed to be verifying the place to exchange goods.
Rowan’s expression turned cold and he asked, “Can you look up the source of the email?”
The technician said helplessly, “I can’t.”
“Let’s go.” Rowan recorded the email’s address and led a group to rush to the location.
No matter whether it was true or false, they had to go inspect and verify it.
Fortunately, the information was correct, and they caught a den for illegal activities.
However, they did not make the connection between the small gang they were chasing and Tobimu, the organization after Shang Ke and Feng Juan, who they had been investigating the entire time.
Over the next two months, the police department received three more similar pieces of information, all from untraceable sources.
Tobimu suffered surprise attacks one after another, and as the situation within became strained, they started to withdraw their influence.
Shang Ke and Feng Juan’s problem was dealt with for now, while Rowan and the other officers became completely involved with Tobimu. Although no one knew, all of this had been encouraged by a “child” from behind the scenes.
After a year, Shang Ke and Feng Juan were sent to a foster family, where they were given a $500 allowance every month. Although Rowan was very reluctant to part with them, he knew that with his job, he did not have the qualifications to take care of them.
That year, Shang Ke and Feng Juan officially became students of Fran Elementary School, and obtained their own English names– “Bruno” and “Ian.”
