You may subconsciously think that it is much more difficult to work harder than facing a computer in a network, but in fact it is not absolute. It can only be said that each software has different defenses for local intrusions and its defense capabilities for network intrusions based on the different functions and the focus of the programmer's work.

After being reminded by Gao Bo, Qu Sen suddenly realized that although he could not break the problem from the front, he knew the software's identification mechanism for network access.

The patches made by May 11 to both software focus on local defense, and there seems to be no security upgrades to the network. In terms of data transmission mechanism, except for adding regional identification modules to the relay station management software, no changes have been made in other aspects.

Especially for the relay station system, its function is to transfer. As long as you connect a virtual device port, the command to be transferred will be automatically transmitted over.

Compared to cracking the structure of the entire database, it is unknown how many times easier to crack the encoding of a command.

"Ho~Ho~Ho~Ho~" Qu Sen moved the mouse on the computer screen with a silly smile and opened the editing interface of C. His mind recalled the network user connection mechanism and port information of the relay station system, and began to type in the command line with a crackling sound.

At around 11 o'clock in the evening, 51o people returned to the dormitory.

The light was turned off. Everyone saw the first thing they saw when they entered the door. Under the backlight of the laptop monitor, Qu Sen's "pale" and weird expression.

Several people in the dormitory began to whisper, saying that a classmate was infected with something evil. Xiao Nuo, who was always known for his strong logical thinking, soon had his own judgment: "It is probably because a beauty promised something, and that stupid boy was arrested as a foreign worker."

Xiao Nuo's judgment was unanimously recognized by the brothers in the class, but no one who knew the tactful did not disturb the "silly boy" and went back to his own bunk to sleep.

But when I woke up, a fool was wearing a pair of dark circles and was still busy in front of the computer.

In the morning, Qu Yue, Wu Changhe, and Xiao Nuo went home with their suitcases. Ge Cunshan and Liu Wei stayed at the nursing school during the summer vacation. Although they didn't leave, they went to the computer room to fight. Before going home, Gao Bo was worried that Qu Sen would starve to death next to the computer, so he kindly went to the service club to buy some bread, ham sausages, cola and so on the long table.

Seeing Qu Sen grabbing the bread and holding it in his mouth, his hands were still busy on the keyboard, he sighed and took out a simple bag.

Qu Sen was not devoted to it and couldn't even take care of eating. It was just because Zhou Li gave her a deadline that was too short and she didn't dare to waste any time. Not to mention eating, she couldn't hold it in and she would trot in the toilet.

After sitting in front of the computer for a night and spending more than half a day, Qu Sen finally used C to write a small software that could run on his mobile phone. He intervened in the computer through a data cable to simulate a network environment.

After some parameter debugging, I finally connected to the signal relay system, but the connection request has not been passed. This is because Qu Sen's forged identity identification code is still incomplete.

I worked hard until midnight. After countless failures, the connection status of the mobile phone software interface finally showed that the access was successful.

"Haha~hehe~he..." A series of strange laughter suddenly sounded in the quiet dormitory. Ge Cunshan and Liu Wei were frightened and sat up from the bed, with four eyes looking at Qu Sen, who was holding his cell phone and smiling.

"I'll go, Qu Sen, you're crazy!" Ge Cunshan asked with some concern.

"It's okay, it's okay! You sleep with you." Qu Sen came back to his senses and said to Ge Cunshan apologetically.

"Sleeping nonsense! You kid smiled like a mental illness." Liu Wei breathed a sigh of relief after confirming that Qu Sen looked normal.

"I'm not sick, I'm not sick, I'll go to bed right away!" Qu Sen comforted Liu Wei, and was playing with something toward the computer.

Ge Cunshan and Liu Wei looked at each other, both of which looked like they were going crazy, but it was hard to say anything else, so they could only lie down and continue to sleep.

Qu Sen did not break his promise, and sweared on the computer for a while, left and sat for a day and night for a chair, and pierced his head on his bed, and a snoring sounded after a while.

The message transferred from the relay station system has been successfully received by Qu Sen, and the data packet is only a few kB. Next, the computer has to calculate the encoding mode of this message. Qu Sen, who is already trapped, has no idea how to start even if he wants to help.

When Ge Cunshan and Liu Wei woke up in the morning, they saw Qu Sen lying on the bed without taking off his shoes. They seemed to have never moved since they started sleeping. The two of them ignored him and went to the computer room after breakfast.

After lunch, Ge Cunshan was going to come back to take over. When he saw that Qu Sen had not come to eat, he made a serving for him.

When I returned to the dormitory, I saw that the "silly boy" was still sleeping with his head covered. While he was hesitating whether to ask him to get up, a crisp "ding" sound suddenly made a notebook.

Before Ge Cunshan could react, Qu Sen had already cried out and got up from the bed. He hit the back of his head heavily on the edge of the bed without any care. He stepped to the table, grabbed the mouse and shook it twice.

After the laptop screen was awakened from the power saving mode, Qu Sen first glanced sleepyly, and was stunned for five seconds, and then a night-like laughter gushed out of his throat.

"You're crazy!" Ge Cunshan couldn't help but lose his words when he looked at Qu Sen's crazy look.

"No, no, no, no, no, no, my buddy is normal, very normal!" Qu Sen still couldn't hide the smile on his face when he replied.

"Just eat quickly if you're not crazy!" Ge Cunshan put the food he had brought back on the table, picked up his armed belt and pulled it out of the dormitory while leaving the dormitory.

He will take over the job in three minutes, so he doesn't have that time to watch Qu Senmai.

Going down to the first floor, after Ge Cunshan and the students on duty at the door completed the handover, the laid-off students rushed to the cafeteria in panic. As soon as Ge Cunshan sat down at the duty position, he heard another burst of cunning laughter upstairs. You don’t have to look at the sound to know that it was Qu Sen’s already crazy guy.

Ge Cunshan shook his head and ignored what Qu Sen was laughing at, and looked through the registration records of the previous shifts.

Within five minutes, a series of rapid footsteps sounded downstairs in the direction of the stairs, and then Ge Cunshan saw Qu Sen carrying his notebook and rushing out of the dormitory building.

Qu Sen ran to Professor Wu's work room for a while, suddenly a smirk appeared on his face, and he slowed down the next second and slowly walked.

In Professor Wu's workshop, Zhou Li is still trying to improve the anti-interference ability of the drone by optimizing the encoding method of the drone's audio and video data, and installing error correction plug-ins on the control end.

However, after this period of continuous attempts, she had no choice but to find out that although these two methods had some effects, to fundamentally solve the problem, she had to find a solution from the hardware.

Helplessly, he pulled the keyboard drawer into the computer desk, stretched his waist and turned his head to look at Li Ying who was doing nothing: "Are you sure you want to go home? Are you not afraid that your dad will give you a look again?"

"I have to go back. My mother has called me several times." Li Ying had adapted to her longer head and straightened it out with her hands. She glanced at Zhou Li, and asked with a wicked smile: "Where are you? You don't really want to go home with our classmate Qu Sen, right?"

"Ha, it doesn't matter whether I want it or not. The key depends on whether he has the ability." Miss Zhou smiled proudly, and she was determined in her heart that Qu Sen could not break the database of the two software within the specified time.

"Don't be proud. The encoding modes of the two relay station systems and the command system database are the same. As long as Qu Sen breaks one, the other basically doesn't have to spend any more time." Li Ying reminded with malicious intentions.

Zhou Li laughed: "Miss has calculated accurately. As for the calculation degree of his laptop, no matter which software database is used, it will take at least half a month to complete the decoding. You little eunuch, don't worry about the emperor."

“…”

When the two girls were hurting each other, the door of the workshop was opened from outside. None of them turned around and walked in without knocking at this time, there was no one except Qu Sen.

When Li Ying saw Qu Sen weakly and found a chair to sit down, there were still dark circles around her eyes, and her face might not have been washed, she realized in her heart.

He asked with a smile: "How about the master Qu, can you handle it?"

Qu Sen didn't say anything, but just looked at Li Ying with a little "sad" and anger.

"Oh, it seems that Master Qu is having trouble. Why don't you beg me, Sister Li doesn't mind helping you." Li Ying raised her eyebrows playfully at Qu Sen when she spoke.

"No need for you, if you have the ability, you can break it and show me!" Qu Sen said the first half of the sentence to Li Ying, and turned his head to Zhou Li.

"Stop, when I can't guess your little thoughts, I just want to steal the sect from this lady." Zhou Li looked through Qu Sen's expression and said proudly: "I'll tell you, you have less than one day left. After a little while, Yingying and I will book a ticket and go home."

"I just don't believe you can break it. Don't worry, no matter what technique you use, I will never learn it." Qu Sen said angrily.

"Okay, okay, let you see it for a long time~" Miss Zhou said in a brisk tone with a slight tone.
