As soon as these words came out, the few sword cultivators burst into laughter, as if they heard some big joke. .

Qi Yun even said, "What's the matter? Do you still want to call the police?"

Calling the police is also possible.

But it will take at least two or three hours to get here from the foot of the mountain. When the police arrive, the place will be over long ago.

And... Lin Xun thought for a while, these immortals may have different strengths from ordinary people, and the police may not be able to do anything about them.

He didn't speak either. He held the keyboard with his left hand and tapped on the keyboard with his right hand to call up an alternate program.

On the other side, Qi Yun didn't know what he was doing, so he said loudly: "This junior brother, you don't need to control the knife - if you play the piano and attack with the rhythm, that's all - you're typing on the keyboard, you're just trying to laugh. kill me?"

A sword behind him said: "Brother Qi, I think he is trying to confuse us. When we laugh, our skill is not as good as before, and he can win."

Lin Xun: "..."

The voices of these Jianxiu were quite young, and their tone was like that of the youth of society. Seeing their arrogance and arrogance, they didn't come to fight with themselves first, but instead made sarcastic words, they probably felt that the victory was in their hands.

However, their taunting skills were an opportunity for Lin Xun - he could call up the appropriate program first, and he didn't have to tap the keyboard again during the battle.

At the same time, Lantern said in a low voice behind him: "Senior Brother Lin, Qi Yun is now in the foundation-building stage, and the others are in the Qi-refining stage. Qi Yun has been in the foundation-building stage for a year, and he is best at quick swords, and sometimes I will form a sword formation with those few people."

Lin Xun: "Okay."

At this time, Qi Yun also ended his taunting behavior and came out with his sword: "It doesn't matter what magic weapon you use, you and I will see the true chapter under the sword!"

His sword is bright.

In the dark night, the sword light was like a long rainbow, stabbing straight at Lin Xun from the front!

However, it wasn't just the sword that struck.

Lin Xun felt that the air around him was stagnant for a moment, and the air pressure dropped rapidly, as if something was pressing him.

He used a light lift and slid to the left.

The next moment, he felt a cold and sharp breath sweeping from another direction!

Lantern said that Qi Yun was good at fast swords, and his sword was really fast!

If it wasn't for the lightening technique that made him dodge much faster, and the sword qi was blocked by the firewall again, Lin Xun had no doubt that he would be hit by a sword qi!

He quickly floated back a few meters.

Qi Yun snorted coldly: "Your defensive barrier is pretty good!"

The next moment, this man suddenly stabbed him with a sword!

The long sword almost left an afterimage in the air, Lin Xun tilted his head to hide, jumped up and down, folded back between the rise and fall, and avoided another blow.

He stared at Qi Yun intently, and the lightening technique was pushed to the extreme. For a time, the two of you avoided me and chased, and it was counted as a few rounds.

Qi Yun said, "Did you have another tortoise in Qingcheng Mountain!"

Lantern Festival hid behind a tree: "You are bullying the disciples of Qi refining by relying on the foundation period, so shameless!"

Qi Yun said: "I know he is Lianqi, but I don't know my sword!"

The next moment, Lin Xun felt the pressure on his body instantly increase, and his speed of movement was also hindered.

but…

Just now, he was indeed avoiding Qi Yun's moves, but more importantly, he wanted to read the code on Qi Yun's body!

In the past few rounds, he has almost understood the program rolling on Qi Yun's body - the attack method used by this person is a very simple but effective method, which is between legal and illegal.

-In the real world, Qi Yun's sword qi madly attacked Lin Xun's body, and in Lin Xun's eyes, it was Qi Yun who sent data packets to him madly!

The old mobile phone ten years ago has limited memory. If someone maliciously sends text messages or emails hundreds of times a second with malicious software, the memory will be filled quickly, the system will be blocked, and then it will crash - the same principle can be analogized Up to now, if the data received by Lin Xun exceeds the load of the system, the operation of the entire system will be blocked, and even the whole line will collapse!

However, this method is also very old, and for Lin Xun, there is nothing new.

—In the field of cyberattacks, what is not new to Lin Xun, to Wang Anquan, it is all old fashioned.

The information bombardment in the area, how can I do anything about the firewall made by Wang Security

At this moment, Qi Yun's sword has reached the point where it is difficult to catch the naked eye. Lin Xun's field of vision is full of sword shadows. The sword qi seals all his possible escape routes, and then a powerful sword qi goes straight towards him. His face is down!

Lin Xun didn't move.

The sword's edge whistled, until the next moment when it was about to fall on Lin Xun, Qi Yun didn't see any intention of withdrawing. Lin Xun raised his head to meet Qi Yun's gaze, and saw the fierceness in his eyes!

—Surely not a civilized person.

But what about society

Lin Xun didn't hide or avoid it, and he didn't even blink. The next moment, the sword light seemed to suddenly hit the copper wall and the iron wall, not only stagnant for a moment, but even shocked Qi Yun to take two steps back!

Qi Yun's eyes showed surprise.

In the same second, Lin Xun narrowed his eyes, pressed the keyboard, and typed the first f11.

This time, not a worm against a neighbor, but a Trojan.

This is also a conjecture of Lin Xun.

A Trojan horse is actually two programs, a controller and a server. The controller stays on Lin Xun's side, and the server invades the other party's system. After the Trojan is implanted, the owner of the Trojan can control the computer of the other party through its own controller.

- This is also a conjecture of Lin Xun.

Now, he has no way to rewrite other people's programs, so, can it be done by implanting a Trojan horse

In three seconds, the Trojan was launched!

The program running interface is refreshed!

feasible!

At the same time, Qi Yun's side was also in the same predicament as his neighbors in the morning - no matter how he slashed and stabbed, he couldn't touch a single strand of Lin Xun's hair.

Just listen to him sternly: "Let's form!"

With an order, the few sword cultivators behind him immediately dispersed into a strange formation, chomping in one hand and holding the sword in the other, to outflank Lin Xun.

Lin Xun glanced at their programs.

-Yes, it has been upgraded from a single attack to a ddos distributed attack.

Multiple computers are united to form an attack platform. Compared with one machine, the attack power can increase explosively.

He jumped up and landed on the treetops of the ancient trees in the mountains, and quickly tapped on the keyboard with his right hand.

Qi Yun: "How long can you last?"

His arms spread out like a roc spreading his wings, his steps seemed to have a strange rhythm, and he rushed towards Lin Xun!

And the few sword cultivators who formed the formation also straightened their swords, and the long swords stabbed Lin Xun from all directions.

Lin Xun tapped the keyboard non-stop, and the crisp tapping sound of cherry even made him feel relaxed.

Just when all the sword tips were approaching, he looked like he was about to be stabbed into a hornet's nest!

- Lin Xun's right index finger returned to the f11 and pressed it lightly.

Qi Yun's figure suddenly stopped.

Lin Xun looked at the error message that popped up on his program interface and tilted his head at him.

The man kept talking during the fight, and he couldn't help but think out loud—he thought so, and he did.

"Senior brother." Lin Xun said, "Acceptance."

In the next second, Qi Yun coughed, as if he had suffered an internal injury, and in the next second, the long sword was released, and he suddenly fell back to the ground.

In the third second, he coughed violently: "I...why is my infuriating disorder...!"

And in the third second, the other sword cultivators who were connected to him also fell down like dumplings.

Lin Xun ended the battle and fluttered in front of him holding the keyboard.

He leaned over and picked up Qi Yun's sword, and walked towards Lantern Festival: "I don't know how to explain it to you, have you studied computers?"

- In fact, what he did was very simple, and he added another paragraph to the core of Qi Yun's code.

Although it was only a paragraph, because of changing a key variable, Qi Yun's entire cycle was messed up.

Infinite loop, buffer overflow - a series of error messages, can be said to be a disaster.

Qi Yun did not say that he did not learn computer science, but took a few breaths: "Give me back the sword!"

Lin Xun: "Control knives."

Qi Yun: "...you!"

But his breath was getting more and more rapid, and he couldn't say the whole thing.

A sword cultivator said: "Senior brother, we have to go to the master to regulate our infuriating energy! Otherwise, the meridians may be destroyed, and we will go to hell!"

Lin Xun turned his head and glanced at them, and saw these people supporting each other, stumbled to the south.

Qi Yun looked back at him, and at the keyboard in his hand, with horror in his eyes, but he still didn't give in: "Wait!"

After they left, Lantern Festival came out from behind the tree, blinked his eyes, and was a little stunned, but his tone was more of worship: "Senior Brother Lin, how did you do it?"

Lin Xun: "The Secret Technique of the Promise Sect."

Lantern Festival: "Wow..."

Lin Xun put the keyboard back in his bag, looked at the sword, and said to himself, "What about this?"

"Senior brother..." Lantern said, "you, you, why did you take his sword?"

Lin Xun: "The tools for committing crimes are confiscated."

"But...but...but," Yuan Xiao's eyes widened: "That's a Jianxiu, Jianxiu. If you take Jianxiu's sword, it's like killing his parents. He will come after you next!" Maybe even his master will come!"

Lin Xun looked at the sword in his hand: "..."

He and Lantern looked at each other.

Lantern Festival was frightened and excited: "They came to Qingcheng Mountain to provoke them, relying on their ability to fight, but in the end they lost their swords! It's going to be laughed at when it spreads out.

Lin Xun smiled.

Him: "Then we are now?"

They glanced at each other again, and invariably accelerated their pace and walked towards the Qingcheng Hall.

- Thirty-six strategies, slipping is the best, looking for the protection of the master and the uncle is the best.

On the way, Lantern said: "Senior brother, why are you so calm?"

Lin Xun: "Calm down?"

Lantern shivered and said, "Although I am cultivating immortals, I haven't gotten used to it yet... As soon as his sword came over, I was scared to death, so I would just run and close my eyes and wait to die. But my brother just started cultivating immortals, and he was cut so many times. , without blinking."

Lin Xun thought.

After thinking for five minutes, he said, "Because I'm a programmer."

The life of a programmer, which looks dull, is actually very exciting.

A program takes a long time to write - but you won't know how many bugs it has until it runs.

When a person lives such a life: facing hundreds of lines of code in the compiler every day, after pressing the run button, a random number of bugs will be opened. After a few years, his psychological quality must be the same as that of ordinary people. different.
