Su Yun quickly chased after him, trying to keep Zhang Qiu, but in the end he didn't succeed. So he handed the check for 10,000 yuan to Zhang Qiu, but Zhang Qiu was worried and didn't know how to use it.

"If you are troublesome, tell me the bank card number, and I will send it to you when the time comes." Su Yun said.

Zhang Qiu was a little embarrassed, and wanted to say that he didn't have a bank card, but he was afraid that Su Yun would suspect that he didn't trust her, so he said, "Is Alipay okay?" ”

He really doesn't have a bank card number, but Alipay does, although he never rushes money into it.

"Okay." Su Yun nodded. So Zhang Qiu told her his Alipay number, and then left Fang Feiyi. He is not afraid that Su Yun will swallow the money, which is not only a kind of trust, but also a kind of confidence and test.

Although 10,000 yuan is a lot for him, but the money is too easy to come by, and he doesn't feel anything.

Back in the dormitory, Zhang Qiu began to think about building his own system, his own firewall and anti-virus software.

The real masters, the systems they use are all modified by themselves, the systems that are tailored for themselves, and the same is true for firewalls and anti-virus software.

It is unrealistic for a person to write a completely new operating system, even if Zhang Qiu is a world-class technology. It's not that it can't be done, but it's too time-consuming and energy-consuming, and it's not worth it or too late.

The Windows system, also known as Windows, has a closed kernel and is not open source, so there is not much room for modification, and there is a copyright risk. However, there are not many powerful and mature operating systems like Windows, so open-source Linux and Nuix have become the first choice.

Zhang Qiu chose Linux.

Even if it's just a modification on an existing system, it's not that easy, and it's not something that can be done overnight.

The first thing Zhang Qiu had to do was to create a dual system, a dual system that hid Linux under the Windows system, but in fact controlled by Linux with the highest authority of the computer.

With an idea, Zhang Qiu began to use his knowledge to analyze. Soon there was a practical plan and it began to be implemented. To do this, it is not difficult for Zhang Qiu technically, the difficulty is the number of codes, whether you are high or not, it is there, even if there is an increase or a decrease, the amplitude will not be very large.

Therefore, for Zhang Qiu, who is not short of technology, it is the most difficult to type out these codes, which requires a lot of physical and energetic efforts.

Fighting until the night, Zhang Qiu preliminarily completed the system. Nowadays, even if the average person gets his computer, he can only enter the Windows system, and he can't tell that this is a dual-system computer.

Only after switching to the super administrator account with the highest authority, you can switch to the Linux system with the password and password of Guò Zhang Qiu. In fact, it is this Linux system that controls this computer, including Windows on the surface, which is under the control of this computer.

All protected texts can only be changed under this system. And the general text jiàn,It can't be completely deleted under Windows.,At most, it can only be put in the recycle bin.。

By doing so, his computer is secure enough. At least a national-level hacker can touch the threshold of his computer, and this is still if he is not prepared.

If you continue to modify that Linux and improve various security settings in the future, even world-class hackers may not be able to defeat Zhang Qiu's computer.

At night, looking at the countdown to the upgrade of the Someiyi system, Zhang Qiu slowly fell asleep.

The next day, he was woken up by Ning Lan's phone call.

"Brother Qiu, remember to pick me up. Are you up yet? If you don't get up again, I'll tickle you......"

Zhang Qiu agreed to come down and got up with difficulty.

Usually you have to get up at six o'clock in class, and some students who get up early get up at five o'clock. And today, after washing, it was already more than eight o'clock, which was a real lazy sleep for the senior party.

At about nine o'clock, Zhang Qiu had already arrived at the school gate of Ninglan. Looking at the countdown to the system upgrade, there are only 60 minutes left to count.

Zhang Qiu thought to himself, if he accompanied Ning Lan for a little shopping, he would probably be able to complete the upgrade, and he was really looking forward to what it would become after the upgrade.

was about to call Ning Lan, but she called first.

"Brother Qiu, where are you?"

"At your school gates."

"Ahh So fast! We're at the school gate, and you go to the stone lion on the right. ”

Zhang Qiu himself was standing next to the stone lion on the left, and couldn't help but look to the right when he heard it, and sure enough, he saw a cute Ninglan girl on the phone. Immediately hung up the phone and walked over with a smile.

Although Ning Lan is not as goddessy as Lin Lai, she is not as mature and charming as Su Yun, and she is not as cold and glamorous as Mr. Mu, but she cannot deny that she is a beauty. At least it's a class flower level.,Maybe you can also evaluate the school flower.,After all, the girl resources in each school are different.。

Such a beautiful woman was already eye-catching, although she stood next to the stone lion and blocked the sight of many people, but she was still able to attract the sideways glances of students passing by.

Who knows, such a beautiful and lovely girl actually waved to a turtle wearing tattered old clothes with a dilapidated functional machine in her hand, and called sweetly: "Brother Qiu!" ”

It's really hard to beat that "Brother Qiu" to death. It's better to call my brother directly, and it's not so hateful.

If sight could kill, Zhang Qiu had already died many times.

"This is my classmate." When Zhang Qiu walked to the side, Ning Lan pointed to a female classmate with a ponytail next to her. Then he introduced to the female classmate: "This is my brother." ”

However, the names of both parties were not introduced, and Zhang Qiu was not surprised. For high school students, many times it is used to not introducing names. And many times no one minds this, and if you are interested, you will naturally find a way to hook up and know the name.

"Hello!" Zhang Qiu said hello and looked at the girl. There is nothing surprising in terms of appearance or dress, but the person is also well-rounded and well-proportioned, and going out can make people feel the youthful vitality of female students. It's not amazing, but it can attract some heads.

Zhang Qiu couldn't help but feel a little disappointed in his heart, but he didn't show it on his face. He had been looking forward to it for a while before, and said that the good classmate would be the beautiful girl in Ning Lan's photo? As a result, the answer is no, so I will naturally be a little disappointed.

But it's better than an ugly girl, and you can't be dissatisfied anymore.

If it was said before, even if this girl was like this, Zhang Qiu didn't dare to approach, didn't dare to talk to her loudly, and might blush. But now, it's this girl who blushes.

Hearing Zhang Qiu's greeting, she nodded lightly and said, "Hello." "He doesn't seem to be very sociable.

After Ning Lan finished introducing, she stretched out her little hand and said, "Where's the mobile phone?" Lend me to play. ”

Zhang Qiu knew that it was Ning Lan who said it yesterday, and he didn't lie to it, so he escaped directly and handed it over.

"Hey, Ning Lan, isn't this your old mobile phone?" The girl will not be shy when facing Ning Lan, and she speaks very fluently.

"Yes! I exchanged mobile phones with Brother Qiu. This iPhone5s is his, but now the right to use it belongs to me. Ning Landao said with a feeling of happiness in his heart.

Although there are more than 5,000 mobile phones, there are many people who can afford them, but there are even more people who can't afford them and are reluctant to buy them. Otherwise, there won't be so many second-hand forces, thinking that you can pretend to be forced by buying an Apple mobile phone.

Like Ning Lan's family, she is reluctant to buy it, even if she has money, she may not be willing to buy it. But it doesn't mean that she doesn't want it in her heart, after all, from the perspective of mobile phones, iPhone5s is indeed a good phone. Therefore, Zhang Qiu can buy her an iPhone as soon as she makes money, which will make her feel happy.

Although, in the end, she didn't fully embrace the phone. Instead, he used the method of "exchange" to obtain the right to use this mobile phone. But this is just her self-esteem that made her do this, after all, although she wanted it in her heart, there was no reason to accept such a valuable gift from Zhang Qiu.

"Wow, your brother is so nice. It turns out that this is how your mobile phone came, I thought you were in love, who gave it away. Hee-hee! The girl said.

Ning Lan blushed, spat her and said, "You're just in love!" Am I like the kind of brain-dead woman who sold herself for a mobile phone? ”

The girl stuck out her tongue and diverted the subject: "Let's go shopping." ”

"Hmm. I don't go to the commercial street today, and it's uncomfortable to be crowded with people. Ning Lan said as she picked up the girl and walked along the avenue next to the school.

Zhang Qiu silently did not speak and followed behind. The girl was dragged away before replying, "It's okay, there are few people on the main road." ”

So the three of them walked to the side, the two little girls were chatting and chatting, and Zhang Qiu was paying attention to the surrounding environment. He always had a bad premonition.

At this time, he found that just after they left, several people also came towards the side where no one had left. And those people were all very tall, loosely dressed, and they looked like students.

"Let's hope it's okay!" Zhang Qiu tilted his head slightly and looked at them from the corner of his eye.

Walking all the way to the end of the school wall, there was an underpass, but no one walked. On the stairs of the underground passage, there were several people who looked like construction workers enjoying the coolness, and when one of them saw the two daughters of Ning Lan, his eyes lit up obviously.

"How can there be migrant workers here?" Looking around, there was no crane in sight, and there was no obvious sound of construction on the construction site. Zhang Qiu couldn't help but be a little puzzled. At this time, the young men who did not look like students in the back suddenly sped up.

The bad premonition was even stronger, and after a pause, Zhang Qiu said, "Let's take the crosswalk!" "Pedestrian crossings are at least open-air, open and open, and nothing is better than an underpass.

The two girls couldn't help but feel a little crowded when they saw that the stairs were not very wide, and they were all uncles.

"Hmm."

At this moment, a migrant worker suddenly stood up and said, "Little baby, what do you mean?" When they see us, they have to take a detour and discriminate against us migrant workers, right? ”

As soon as the migrant worker said this, the others also stood up. This formation immediately frightened the two girls. Generally speaking, migrant workers are honest and quiet people, unless the boss owes wages, they will be fierce.

But when did it become so fierce? Didn't you just say a word about walking on the sidewalk? He even jumped up and said that he was discriminating against them. Ning Lan couldn't help but scold angrily: "Sick!" ”

"**Only then can I get sick! Look at it, look at it! Brothers! Lao Tzu said that they discriminated against us! They all scolded people! ”

"Don't think that Lao Tzu doesn't know you city babies, but dogs look down on people! Treat us migrant workers as inappropriate people, right? Lao Tzu beat the little white face next to you today and didn't look like a human! ”

"Beat him to death! How dare you discriminate against Lao Tzu! ”

"Teach them a lesson today! If you dare to discriminate against us, we are justified when we go to the police station! ”

"These two chicks are nice! Dare to discriminate against your uncle, let you taste the greatness of your uncle in a while! ”

The bad premonition before finally happened. Zhang Qiu was sure that these people were definitely not migrant workers, but hooligans in disguise. As for why the camouflage, the purpose is already self-evident.

"Go quickly, go ahead." Looking at the few people who didn't look like students following behind, Zhang Qiu already knew that he couldn't let them run in the direction of the school.
