After a long while, Su Muxin calmed down.

After a tiring morning, feeling a little hungry, she subconsciously looked in the direction of Lin Yu.

After finding that he seemed to have just finished dealing with things at work, Su Muxin's eyes couldn't help but light up, and then looked at him pitifully: "Uncle, I'm hungry, I want to eat Kung Pao Chicken." ”

After speaking, she also winked at Lin Yu with her big eyes, looking like she thought I was cute.

Lin Yu: "......"

Although this little kid looks seven or eight points similar to Su Muyun, Lin Yu doesn't know why, he can't find the slightest shadow of Su Muyun from her.

I don't know if it's because of her personality or the difference in temperament, Lin Yu has no waves in her heart for her coquettishness and cuteness.

"Well, just wait."

Lin Yu glanced at her, looked at the time on the computer at eleven forty, answered lightly, and said lightly.

After that, he walked towards the kitchen with Su Muxin's happy smile.

After simply washing rice and cooking, Lin Yu went to ask Su Muyun what he wanted to eat, and the answer he got was the same as he thought, that is, sweet and sour tenderloin.

Soon, after more than an hour of busyness, three dishes and one soup were also slowly out of the pot, namely sweet and sour tenderloin, kung pao chicken, braised pork ribs, and seaweed egg drop soup.

Finally, Lin Yu also prepared a plate of after-dinner fruits to ensure balanced nutrition.

After the three of them had a simple lunch, Su Muxin obediently went to brush the dishes.

And Su Muyun didn't sleep well last night and morning, so he wanted to take a nap and take a nap.

Of course, after hearing this good news, Lin Yu also smiled and said that he wanted to go together.

It's just that as soon as he put forward this suggestion, Su Muyun ruthlessly vetoed it.

Because she knew that once Lin Yu went, it would definitely be the same as in the morning.

In this way, she will not be able to broadcast the live broadcast in the afternoon.

In fact, with Lin Yu's current net worth, even if Su Muyun doesn't go live broadcast, he has been raising her, and the two of them can also live well.

However, Lin Yu would never tell her about it, because he knew in his heart that with Su Muyun's temperament, he would never be a canary attached to him.

After all, two people's lives require both parties to support and maintain each other, and this kind of thing has nothing to do with the amount of income.

After the suggestion was rejected, Lin Yu could only watch Su Muyun go back to the bedroom to sleep alone.

I reluctantly returned to the living room, ready to continue typing code in the afternoon to complete the defensive wall.

At the same time, Su Muxin also happened to finish washing the dishes, and the two sat on the sofa in the living room again, each holding the computer, busy with their own things.

Around half past one noon.

After typing the last streamlined code in my mind, the last program in the display is slowly formed.

And with the formation of this last program, the firewall of the entire computer is also completely completed.

The firewall, simply put, means that all the network communication and data packets flowing in and out of the computer must pass through it, like a wall, blocking the connection between the outside network and the inside network.

It can be either a proprietary piece of hardware or software that sits between the computer and the network to which it is connected.

The firewall edited by Lin Yu belongs to the latter, which is a software set up on exclusive hardware.

Looking at the firewall containing countless calculations and thousands of programs on the screen, Lin Yu also nodded with satisfaction and turned off the [Super Brain] skill.

This firewall, Lin Yu plans to name it "The Great Wall".

As for why it is named "The Great Wall", it is because Lin Yu feels that if others want to break through their firewall, they must go through many difficulties and obstacles like crossing the Great Wall that stretches for thousands of miles before they can reach their feet.

At present, there are three lines of defense for the entire "Great Wall" firewall.

The first line of defense consists of countless broilers forming the defense nodes, forming the outer wall of the "Great Wall".

As long as someone attacks the outer wall, the packets sent by the intruder through the DDOS attack will be divided equally among all the broilers to deal with the useless packets.

In other words, if the intruder wants to break through the first line of defense of the firewall, he needs to break through all the broilers in Lin Yu's hands first.

THIS CAN ONLY BE DONE BY DDOS ATTACKS, AND OTHER MEANS ARE USELESS.

Of course, in addition to this method, if the intruder wants to break through Lin Yu's firewall, he can also find its loopholes to achieve the purpose of breaking through the firewall.

It's just that with Lin Yu's firewall laid out close to god-level computer technology, to put it bluntly, hackers around the world basically can't find any loopholes.

Therefore, they have no other way than to use DDOS attacks to break through the first layer of defense of the firewall.

With DDOS attacks, it is necessary to compare the number of broilers and secondary machines on both sides, and also to see the configuration of each computer on both sides.

This is equivalent to fighting a war between two camps in ancient times, whoever has more soldiers and who has stronger soldiers will be able to win.

Generally speaking, the number of troops on both sides is estimated before the start of the war, which is a prerequisite for all hackers to use DDOS attacks.

But this first line of defense is different, its strength is incalculable, and it can be increased at any time.

Because one of its programs and the chicken catching tool on Lin Yu's computer are bound to each other.

Once it is found that the broilers have collapsed and disappeared, or the number is insufficient, then the broilers on the chicken catching tools will be continuously replenished into the first line of defense.

It is guaranteed to continue fighting in an infinite loop until all the broilers collapse, or the chicken catching tools are too busy.

It can be said that the first line of defense of the "Great Wall" firewall may not be the most difficult, but it is definitely the most headache and despair for intruders.

Of course, this first line of defense can only stop the vast majority of hackers.

For those veteran hackers who have their own attack methods, they only need to manipulate the origin point to carry out a gathering point attack to break through the first line of defense.

This way they will enter the second line of defense specifically against them.

The second line of defense consisted of high-level auxiliary aircraft, forming the inner wall of the "Great Wall".

They are bound to various tools in Lin Yu's computer.

Once an attacker from a hacker enters the second line of defense, a high-end secondary machine will connect with the attack tool in Lin Yu's computer, and then attack each other with the intruder until the other party is killed.

If it is an intrusion hacker, then there will naturally be another high-end secondary machine connected to the infestation tool to bombard and kill the intruder.

Not only that, these high-end secondary machines can also cooperate with each other to form a special combination of invasion, defense, and attack, which is very powerful.

Basically, it's more than enough to deal with the old bird hackers, unless it's a hacker who can cycle continuously, otherwise it's no fun at all.

As for the last line of defense, it is composed of Lin Yu's own machine, and it is also the simplest and purest line of defense.

Because Lin Yu only set up an impregnable defense program inside, as well as a program for early warning.

This defense program is a small firewall edited by Lin Yu alone, whether it is the DDOS attack of ordinary hackers, or the attack mode of old hackers themselves, it can be blocked.

And once this program is activated, then Lin Yu's computer host will fully defend against all external attacks within three minutes, and send Lin Yu an early warning.

After the early warning, it was up to Lin Yu himself to deal with those intruders.

However, Lin Yu felt that there should be no intruder in this world that he could solve by himself.

Just when Lin Yu looked at his firewall with satisfaction, Su Muxin's computer not far away suddenly emitted an alarm like a "down" machine

Hearing the familiar alarm sound of the firewall being invaded, Lin Yu came back to his senses, raised his eyebrows, and subconsciously looked in the direction of Su Muxin.

I saw Su Muxin, who was originally lazily leaning on the sofa and putting the computer on her lap, was sitting in a precarious position at this time, staring at the computer screen tightly, her expression was nervous, her face was a little pale, and her eyebrows were full of worry.

Seeing this scene, Lin Yu hurriedly got up and walked over, casting his eyes on her computer screen.

After just one glance, Lin Yu found that Su Muxin was fighting against an unknown hacker at this time.

No, it's not so much a battle as a one-sided chase.

Because in the green war of hackers, apart from destroying or being destroyed, there is only pursuit or being pursued.

Obviously, Su Muxin now belongs to the second type, she was chased by the other party without a backhand, and could only run away frantically among the broilers and springboards.

It's just that Lin Yu knew that she wasn't good at doing this kind of thing when he looked at her speed of escaping.

"How did you provoke someone?"

Looking at the Samsung Danger Index displayed in the firewall program on her screen, Lin Yu couldn't help but ask.

Star danger index, this is the security level of the firewall on Su Muxin's computer.

There are five stars, the higher the star, the safer, and the lower the star, the more dangerous.

At present, there are only three security levels of all firewalls on the market: low, medium, and high, and they are generally medium by default.

But every skilled hacker will set up their own firewall, so the firewall security level of each hacker is different.

Just like Lin Yu's "Great Wall" firewall, it is a progress bar divided into three security levels, which are 30%, 60%, and 90%.

Each security level corresponds to the three lines of defense of the firewall, and once it reaches 90%, the system will frantically alarm and whistle, the kind that does not stop.

After hearing Lin Yu's question, Su Muxin forgot the sense of crisis for a while, couldn't help but look at him with wide eyes, and said in shock: "I'll go!" Uncle, you can understand what I'm doing?!! ”

Oh my God, she thought Lin Yu didn't know anything.

You must know that there are now five or six windows on her computer screen, which are full of various algorithms and corresponding tools.

If it weren't for fellow hackers, ordinary people wouldn't have figured out what they were doing.

As a result, the uncle saw it at a glance, doesn't this mean......

In this regard, Lin Yu just glanced at her lightly and didn't say anything.

Who does this little kid look down on?

At her level of operation, can she still not understand it?

Just like her, Lin Yu unceremoniously said that tens of thousands of himself could hang her up and beat her.

As he spoke, a large number of broilers in the broiler tool on the computer screen disappeared instantly, and then, a large wave of data streams violently caught up with the source data stream (origin point) in Su Muxin's escape

At the same time, the local system was invaded, and the firewall sounded again, and the danger index of the original Samsung dropped to two stars in an instant.

Seeing this scene, Su Muxin instantly came back to her senses, and her expression was a little flustered.

At this time, there are less than 8,000 broilers left, and there are only two auxiliary machines, and if this continues, she will definitely be caught up by the other party, and then the real IP address will be exposed!

If it was before, before the other party found her broiler IP, then she could still forcibly go offline by disconnecting the network.

But it's impossible for her to disconnect from the internet now.

Because once you forcibly go offline, then the other party will track your own machine step by step through the back door you left on the broiler.

In that case, your real IP address will still be exposed, but it's just a matter of time.

In fact, if Su Muxin was using someone else's broadband, then she could have forcibly gone offline and ran away.

Because even if the other party finds the real IP address, it is the one that installs the broadband, and his own information and real address will not be exposed

But the problem is that she is now using her own broadband!

Once forcibly offline, the other party will find Su Muyun's real address, not Su Muxin's!

Because the broadband at home is installed in the name of Su Muyun, the Modu Information Bureau has her detailed information, and the other party will definitely be able to find it as long as he goes to find it.

This truth is not only clear to Su Muxin, but also clear to Lin Yu in his heart.

For this result, Lin Yu also sighed helplessly.

This little kid is really going to cause trouble.

However, it was really time for the other party to come, and it happened that his "Great Wall" firewall had just been completed, so let's try the effect with him.

After making up his mind, Lin Yu returned to his position, tapped on the keyboard with both hands, and said to Su Muxin: "I will open port 7331 to you, you directly access my system, and I will resist him." ”

After speaking, Lin Yu also quickly opened the port on his system.

"Huh?"

Hearing this, Su Muxin was obviously stunned for a moment, and even the movements of her hands paused for a while.

It's just that before she had time to think about it, her original data stream was hit by the chasing data stream behind her again, and the security level of the firewall instantly dropped to one star!

One star, this is an extremely threatening state!

This means that Su Muxin's firewall will be destroyed by the other party at any time in the next second, and then directly find the real IP address!

Piercing sirens rang out one after another.

Seeing this, Su Muxin didn't care about anything else, and hurriedly found the 7331 port opened by Lin Yu and connected to it.

After seeing Su Muxin's successful access, Lin Yu closed the port unhurriedly, and then opened the "Great Wall" firewall, adjusted the security level to the maximum, and activated all three defense lines.

At the same time, the source data stream behind Su Muxin, who was chasing after her, also happened to come over.

After seeing the brand-new firewall in front of him, the other party was stunned for a moment, and then reacted, knowing that someone was coming to answer Su Muxin.

It's just that what surprised Lin Yu was that the other party didn't hesitate at all after seeing him, and directly launched a tentative attack on this new firewall.

Attack data streams rose from the opponent's source data streams, and all of them bombarded the outer wall of hundreds of thousands of broilers.

The outer wall of the first line of defense is composed of dozens of coarse data sets with huge cross-sections, which is simply outrageous.

Therefore, when this stream of attack data hits it, it does not cause any substantial damage to the exterior wall at all, and it can be said that it does not move at all.

If Lin Yu's security level data bar is accurate to 0.001, I am afraid that he should be able to temporarily find that the other party has just launched an attack.

The speed must be very fast, because if it is slower, the bar will instantly revert to full health.

Well, that's the exaggeration.

Therefore, after seeing this scene, Lin Yu also smiled with satisfaction, and even let the "Great Wall" firewall operate alone.

He set his eyes on Su Muxin, who was lying on the sofa softly, her chest was rising and falling violently, and she looked like she was the rest of her life.

Looking at her embarrassed appearance, Lin Yu said calmly: "Let's talk about it, what's going on." ”

Hearing this, Su Muxin did not answer immediately, but breathed a sigh of relief and then said slowly: "I saw in a post in the Red Guest Alliance that the Baqi Group and the Fengmeng Group were engaged in a green war, and then I went to the virtual battlefield to take a look and observe for a while. ”

"In the end, I saw that my hands were a little itchy, so I killed a few peripheral members of the Yagi group by the way, and then I was hunted down by one of their team leaders......

Speaking of this, her voice also weakened, and she couldn't help but sneak a glance at Lin Yu.

"Are you sure?"

Hearing this answer, Lin Yu couldn't help but glance at the Japanese hackers who were constantly attacking his firewall as if he was crazy, looked at her expressionlessly, and said.

Does this little kid think he's stupid?

If she hadn't done anything excessive, why would the hackers attack her firewall so frantically?

However, although this little kid is a little stupid, it is also a beautiful job.

"Uh......"

Looking at Lin Yu's expression of "do you believe it or not", Su Muxin also smiled at him wryly, and obediently explained: "Okay, I just killed more than ten peripheral members of the Baqi Group, and then I also killed more than ten in a virtual battlefield in the morning, adding up to more than thirty." ”

"Who knows what kind of peripheral leader of the Yaqi group is so unbearable, I just destroyed more than a dozen of them, and the peripheral members are like mad dogs, chasing and killing me."

In the end, Su Muxin seemed to be a little angry and muttered something there.

Lin Yu: "......"
