Xia Zhiyi was indeed "lucky" this time.
Or rather, it was an opportunity delivered by the enemy.
Last time it was Fu Chi was being targeted, but this time it's Xia Zhen who is being targeted.
At the time, Xia Zhen lived with Xia Wanyi. When Xia Wanyi went to school, Xia Zhen would occasionally wander around the neighborhood by herself, and then... she was targeted by human traffickers.
The scene was somewhat chaotic. The traffickers pretended to be Xia Zhen's parents and tried to use the same methods they used on other girls, such as scolding and reprimanding, to prevent Xia Zhen from speaking up. Even if she did explain that they didn't know each other, they would try to fool her with excuses like "this child is lying because she is not convinced after being disciplined." Then, before anyone around could react, they would drag Xia Zhen away.
However, since Xia Zhiyi took Xia Zhen in, how could she not have considered Xia Zhen's well-being?
Even though Xia Zhen wasn't living with Xia Zhiyi, but with Xia Wanyi, Xia Zhiyi arranged a training plan for her after confirming that the girl's health had recovered somewhat.
The little girl looks about the same age as her peers, and may even appear not to be overweight due to her physique, but she is actually quite strong and more agile than most people her age.
Even if Xia Zhiyi didn't teach them, the bodyguard who had been silently protecting the two sisters was willing to teach this little girl, who had suffered a lot, some self-defense skills in his spare time.
Therefore, even though the bodyguards who were supposed to be protecting the girl were not present for various reasons, Xia Zhen was not easily taken away by the human traffickers who had ulterior motives. Instead, after realizing that it was not a misunderstanding, she promptly fought back.
Upon receiving the news, Xia Zhiyi was furious, but she also took the opportunity to demonstrate to Xu Liuyi and the others what it meant to be technologically superior.
He went directly to Xu Liuyi, and after briefly explaining what Xia Zhen had encountered, he created a program right in front of her. Within half an hour, the program used the current internet to thoroughly investigate the human traffickers' situation.
At the same time, he also fixed the vulnerability in the monitoring network system that the program had easily exploited when collecting information.
Well, he hacked into the traffic surveillance system with his own program, obtained the traffickers' information, and then remembered to repair the broken door so that no one could get in again.
All of this was done in front of Xu Liuyi.
Afterwards, Xu Liuyi asked many people to try to bypass the places that Xia Zhiyi had tampered with, and found... good heavens, not to mention the monitoring system, the traffic system also had a new firewall, and without proper authorization, it was impossible to break through.
Suddenly I feel so safe.
The internet firewall is of great importance to the Xia Country Xia Country. The existence of the national firewall is primarily for the sake of national interests. However, if this firewall is not strong enough and is compromised, the consequences could be unpredictable.
The West's advocacy of internet freedom and opposition to sovereign states filtering internet information is not merely a matter of personal freedom; it is directly related to national security.
To put it bluntly, even with the firewall in place in Xia Country, Western powers haven't given up on influencing public opinion and stirring up sentiment by bribing some "public intellectuals" in Xia Country. If the firewall didn't exist, or if its defenses were inadequate, allowing Western powers free access, then...
You cannot guarantee that everyone in this world has a brain smart enough to think independently.
Every year, foreign forces attempt to attack the invisible firewall that protects the entire Xia Country, and every year the Xia Country uses various means to update, maintain, and reinforce this firewall.
Fortunately, Xia Country with outstanding people. Not only did the official team perfectly execute the mission, but some talented and patriotic individuals also spontaneously retaliated against those who attempted to attack Xia Country's cyberspace, and the results were quite good.
However, cyber warfare is mostly invisible; most of the time, Ordinary Person don't even realize it has happened before it's over.
The government will also try to recruit these enthusiastic individuals from the public.
Take Li Jing, for example. After he took the initiative to stand out, he was quickly recalled to the country by the authorities and went to contribute to the nation's development.
Xia Zhiyi's importance lies in the fact that he not only upgraded the other party's firewall in a short period of time, but he also added a counterattack system.
This made Xu Liuyi and the others' eyes light up.
Simply defending won't work; the best defense is offense.
Given Xia Country's current foreign policy, they certainly wouldn't do something like attacking others for no reason; that would be beneath the dignity of a great power, wouldn't it? And always waiting for others to attack, then defending themselves, and then letting those young people from the common people attack others—frankly, that's a bit frustrating.
If we could completely upgrade Xia Country's national firewall and add this counterattack function, things would become much more interesting.
Yes, that's interesting.
Xia Zhiyi's counterattack system directly destroyed the beloved machines of several of Li Jing's colleagues. Although everyone was stunned and heartbroken at the same time for losing their "wife," they thought about what would happen if this method were used on the enemy... and things suddenly became interesting.
"You said you can set up Heavenly Net in two years? Is that really possible?" Li Jing asked suddenly, his legs crossed and casually peeling peanuts in his hand.
Xia Zhiyi: "If we want to do it, with the speed of Xia Country, there's nothing we can't do."
Xia Zhiyi: "To be more precise, the two-year timeframe takes into account that setting up Heavenly Net in some mountainous areas would be a bit troublesome. However, if it's only being built in urban areas, as long as there are enough materials, it can be completed in less than two years."
The speed of Xia Country, is that just a joke?
Upon hearing this, Li Jing looked at him and said, "Then why did you tell me it would take five years?"
Xia Zhiyi: "I didn't think it needed to be so fast before."
Li Jing: "Huh?"
Xia Zhiyi turned to look at him. "If I don't act tough, how can I get them to take me seriously enough?"
Li Jing muttered, "Why do you seem so anxious about this? Have you run into some trouble? Do you need my help?"
Xia Zhiyi shook her head. "No need."
He paused for a moment, then added, "But if you have time, it would be best if you could help me take care of my sister."
Li Jing: "Your sister doesn't live with me, how am I supposed to take care of her?"
Xia Zhiyi was silent for a moment, then replied, "Not necessarily, it's hard to say."
Li Jing looked at him in surprise.
Xia Zhiyi remained silent.
He did this without consulting Xia Wanyi, simply following his own ideas.
So far, Xia Wanyi has no idea that she might be carefully protected like a giant panda in the future.
I wonder if my sister will get angry with him because of this...
