One o'clock in the morning.

Li Jiandong opened his eyes dimly, he had been half-asleep all along, and he felt unstable in his heart, so he quickly got up and looked at the computer.

The webpage has been changed again!

It's an eagle again!

DJ soundtrack again!

"This Yiying, how the hell did you do it!" Li Jiandong felt like he was about to go crazy, his face was black and scary, and he couldn't find his sleepiness at all, he quickly opened the source code file, and found that the database could not be overwritten, and it could not be modified directly at all.

He simply stared at the math problem.

Look closely!

Look again!

The high school math Olympiad level and the high difficulty of math problems are definitely not something that ordinary people can do.

Li Jiandong couldn't even understand the question, let alone solve the answer, he suddenly remembered Sun Liang at the gate of the Thirteenth Middle School.

He wrote down Sun Liang's mobile phone number.

"It's good that I'm smart!" Li Jiandong took a deep breath, thinking that it was too late, wouldn't it be good to call over?

It doesn't matter so much, it must be solved quickly!

If it hasn't been solved by the morning, Director Zhou won't be able to explain it, but it doesn't matter if a few people see it, they can't be sure if they have been invaded, and they can have an explanation to the outside world, maybe it's a temporary adjustment, modification, or just a mistake?

Li Jiandong immediately called.

Sun Liang was asleep in a daze, heard the mobile phone vibrate and closed his eyes for a long time, put it in front of him and found that it was an unknown number, out of curiosity he pressed the answer button, and heard the other side say, "Is it Sun Liang's classmate? I am Officer Li, who was looking for you at noon yesterday." ”

Officer Lee...... Okay?"

Sun Liang suddenly became energetic.

Li Jiandong was silent for a long time, he didn't know how to speak, but he still said seriously, "I'm really sorry to disturb you so late, classmate Sun Liang, I have an urgent matter, I have a math problem, can you help me do it again?"

Sun Liang immediately sat up, he turned on the lamp, and asked, "It's so late, is it overtime?"

"One hundred, okay? Twice. ”

"No, I can't. ”

Sun Liang remembered Zhao Yi's words, and immediately shook his head and said, "It's fifty during the day, and you still disturb me to sleep, and if you get up to do the questions again, I won't have the energy to go to class tomorrow, and I will delay my study for a day! Maybe because of this day, I won't be able to get into the ideal university in the college entrance examination?"

"That's it! Five hundred, no two prices! If you don't agree, I'll hang up." ”

Li Jiandong was stunned.

He deducted insurance and money a month, plus a bonus of about 3,000 yuan for full attendance. Five hundred as soon as you open your mouth?

It's too dark, isn't it?

Li Jiandong took a deep breath and swallowed his anger to agree.

Sun Liang felt that he could still negotiate the price, but he didn't expect the other party to really agree, but he still didn't believe it, so he continued, "In this way, if you send me a text message, you will say, 'Make sure to pay me 500 yuan to thank me for helping you with the question', otherwise what if you regret it and don't give it?"

"Give me the money at the school gate tomorrow!"

His character was doubted by a high school student, and Li Jiandong's heart was hit by a second blow, and he agreed in humiliation.

Li Jiandong took a screenshot of the question and sent an MMS message to the past, because of the network transmission speed, Sun Liang waited for a long time to successfully open it, and he was also curious about how difficult the math problem worth 500 yuan was.

Open it and take a look.

"Isn't this the math Olympiad problem I did yesterday at noon?"

Sun Liang looked at the topic in surprise, thinking about the complicated situation of 'Zhao Yi and Officer Li', and finally simply shook his head, "It must be related to Zhao Yi, yes, give Zhao Yi two hundred and five tomorrow." Perhaps, next time this Officer Li, he will spend a thousand yuan to buy the answer!"

Sun Liang symbolically waited for five minutes, and then sent the answer to Li Jiandong.

Li Jiandong looked at the information in surprise.

So fast?

If there is no mistake in the memory of school, the difficulty of the question must be very high, how can it be done so quickly?

"Is it really the same as what my colleague said, this Sun Liang is a mathematical genius?" Li Jiandong suddenly found that he couldn't understand how powerful Xueba was.

He verified.

That's right!

After Li Jiandong put down the phone, he quickly changed the website.

After all the changes were made, he was worried that there was something wrong with his computer, so he simply went to a nearby department, found a new computer, and changed the management entrance, ID and password.

"It's definitely okay this time!"

"Even if I have a problem with my computer, no one else's computer can be a problem!"

This time, Li Jiandong slept very peacefully.

He didn't know what the specific problem was, but even the most advanced hacker could not stay in front of the computer all the time, let alone crack the login entrance, account and password again in a short time.

Li Jiandong was woken up by a phone call.

At about six o'clock in the morning, a colleague from the logistics department called, "Jiandong, don't sleep! Our website has been hacked again!"

"It's still an eagle!"

"Let's go check it out!"

Li Jiandong felt that it was a dream, he changed the website at three o'clock, and he felt that he had just fallen asleep, and someone said that the website was hacked again?

That's too fast, isn't it?

When he turned on the computer to check again, he found that the news picture was still Eagle Flash, and it was still the oratorio dance song when he clicked on it......

Changed math problems?

......

Sun Liang came to report the good news in the morning.

He said excitedly, "Zhao Yi, that Officer Li is looking for me again, it's more than one o'clock in the evening." I slept in a daze, and he asked me to solve the problem. I asked for 500 yuan this time!"

"When I get the money, I'll give you half of it. ”

"By the way, you have appeared. Sun Liang leaned over flatteringly and said, "Let that Officer Li look for me again, this matter must have something to do with you, right!"

"You're smart!"

Zhao Yi said with relief, "Whether there is a next time or not, it depends on the situation." ”

The math Olympiad is approaching.

Zhao Yi and Sun Liang spent a lot of time doing Olympiad problems, they did not have special Olympiad training, they could only improve by doing questions, saw more question types, and learned more about problem solving ideas, which will definitely be helpful to the competition.

Niu Lianhua attaches more importance to them than them, she not only supervises the two of them to do the questions, but also cares about which questions they have done, and finds new question types for the two of them to do.

At noon, she also came to see and urged the two of them to do as many questions as possible.

Zhao Yi was not there.

At noon, Zhao Yi took a taxi to Phoenix Bay Park in the city center, and after meeting his parents on the side of the road, he went to see the houses in the two communities near the park.

Liu Jing and Zhao Zhenxi were optimistic about the two houses, and they couldn't decide which one to buy after hesitating for a long time, so they simply let Zhao Yi decide.

Zhao Yi went to see the first set, it is an eleven-story residential building, there is only one household, the house is on the sixth floor, 170 square meters, three bedrooms and two living rooms are large in area, and the decoration is very ordinary.

He wasn't too satisfied.

Then I went to see the second one.

When he walked to the door of the community, Zhao Yi glanced left and right and was a little surprised, "The community where Lin Xiaoqing's house is located?"

It's normal to think about it.

There are several communities near Phoenix Bay Park in the city center, and the newly opened commercial residences are sold in small square meters of high-rise buildings, or old and dilapidated communities, and there are no more than three communities with large square meters and villa buildings.

Zhao Yi followed the intermediary and happened to meet an acquaintance on the way.

Lin Xudong.

Lin Xudong was walking forward with the phone and greeted Zhao Yi from afar.

"Uncle Lin, didn't you go to work?" Zhao Yi asked with a greeting.

Lin Xudong walked over with some surprise, he had only met Liu Jing and Zhao Zhenxi, and he hadn't really spoken, they were all the parents of the students, and they definitely had to say something.

Several people exchanged pleasantries.

Lin Xudong had a rare day of leisure, he had all the explanations at work, and he went home for a meal at noon, but the phone still couldn't stop, and when he heard that Zhao Yi was looking at the house, he was not in a hurry to leave, so he greeted warmly and said that he would help go to see the house together.

The house they looked at was a front-row villa building, and the unit type was a three-storey building with four households.

Each house has two floors.

This house type is the same as Lin Xiaoqing's house.

As soon as a few people walked to the door, Lin Xudong recognized the house, "Wang Enming sold it, right? His factory is going to be expanded, and he can't raise funds, so he simply sells the house." ”

"This house is very good, it has only been three years, and the decoration is definitely no problem. ”

Lin Xudong said that a few people went in.

The internal structure of the house is the same as Lin Xiaoqing's house, it is a large area of two floors on the upper and lower floors, and the decoration is indeed like what Lin Xudong said, it is really very good, not the kind of golden rich style, but it is a little fresh and a little bookish color, but the materials are absolutely quite exquisite, the furniture looks the same as new, and the electrical equipment is also very complete.

If you buy a full set, you don't even need to add new furniture or electrical appliances.

Zhao Yi was very satisfied.

He stood by the window and looked at the scenery outside, the corners of his mouth couldn't help but smile, and he whispered to his mother, "It's good, that's it!"

"That's it!" Liu Jing asked.

Zhao Yi nodded and said, "That's it, don't choose, it's useless to watch so much, I'm quite satisfied with this." ”

Liu Jing and Zhao Zhenxi were also very satisfied, so they went over there to negotiate with the intermediary.

Lin Xudong walked over and said, "By the way, Zhao Yi, your parents were here just now, I can't say, it's a matter of policing, you have time to write a report on security vulnerabilities, you don't need to be too particular about the format, mainly where there are loopholes and problems." Your name has been reported, and the bonus will come down after a while. ”

"Don't worry, money is indispensable, I'll keep an eye on you. ”

"Okay, thank you, Uncle Lin. ”

Zhao Yi was really reluctant.

How interesting it is to put a math problem every day, Sun Liang also divided half of the money, so he implanted the program code in the website, and it didn't take time to modify the website, just wait for the problem to be released every day.

That's it?

Lin Xudong also thought about the website and found it interesting, he gave a thumbs up and said, "You don't know, what you did is really good." Now that everyone in the police knows the name of 'Yiying', you are very shameless to the group of people in the logistics department. ”

"But ......"

"Our Criminal Investigation Division is very happy, hahaha!"

Lin Xudong laughed as he spoke, he stopped to look out the window, and suddenly found that from this angle, he just saw his home, and the window facing him was......

Sunny bedroom?

"I'm C!!"

Lin Xudong couldn't help but spray a dirty word, he inhaled fiercely with wide eyes, the smile on his face suddenly disappeared, but he looked at Zhao Yi with alert eyes, but he still didn't say anything for a long time.

"I had to leave beforehand. ”

He left a sentence and hurried away.

Zhao Yi looked at Lin Xudong strangely, not understanding what was going on at all, "I guess I remembered something, right? The police are really busy." ”

He continued to look out the window leisurely.

Lin Xudong hurried home, and the first thing he said when he met Zhao Hongjuan was, "Juan'er, hurry up! Change the curtains in Qingqing's bedroom!

"I'll tell you!"

"Zhao Yi's kid, he actually wants to buy Wang Enming's house. Lin Xudong pointed out the window in a little panic, "See?

"What are you anxious about?"

Zhao Hongjuan was a little incomprehensible, "I see, Zhao Yi's kid is very good, he studies well, and he can make money, he only got a million bonuses in high school, if he can buy a house here for Qingqing...... It's quite romantic. ”

"What romance is romantic, how old is Qingqing, you don't know that day, two children were ...... in the living room"

Lin Xudong was anxious all of a sudden.

"What's wrong?"

Lin Xudong still didn't say anything, he gritted his teeth fiercely and said, "Qingqing is still too young, I can't have a boyfriend now, I don't agree! Hurry up and change the curtains, don't let that kid look cheap." Let me tell you, I know these young people best, and he thinks the telescopes are ready......"

Zhao Hongjuan spat disdainfully, "You, you're still a policeman! ”

Meanwhile.

The people in the Police Logistics Department are going crazy.

In the morning, the police knew that the website had been hacked again, and Zhou Hongwen immediately lost his temper, and he couldn't cover up the matter anymore, so he simply went through the process to report.

He called Li Jiandong and scolded him.

I thought that the matter was over, but I didn't expect that there would be a follow-up, and Li Jiandong delayed modifying the webpage back.

What's going on?

Can't you change the web page?

What a shame for the logistics department!

When Zhou Hongwen asked, he knew that it was because of a math problem, and 'Yiying' really didn't go too far, and he left a back door for the modification of the web page, which was a very difficult math problem.

Li Jiandong not only couldn't do it, but he couldn't find the topic on the Internet, he posted the topic to the group, but no one paid attention to it at all.

People in the police department aren't good at doing math.

Zhou Hongwen scolded Li Jiandong again, and then simply called all the people in the logistics department to find a relationship and find a way to solve this math problem.

This is what happened in the office.

"Son, will you do it?"

"Look at the question, it's very important, the task of the leader!"

"Big nephew, you are a top student of Zhengyang University!"

"Aren't you just going to high school? This is a high school topic! Anyone can do it, but you can't do it!"

An hour later.

Zhou Hongwen slapped the notebook with the title in his hand on Li Jiandong's face, "I don't care what method you use, today, you must solve him!"

Li Jiandong could only make a bitter face and came to the gate of the thirteenth middle school again.

He crouched on the side of the road and waited.

I don't know when, it rained lightly in the sky.

A cold wind blows.

A young man with yellow hair walked over with a figure-eight step, his earset stuffed in his ear, and his mouth sang affectionately--

“......

The tears that dripped can not be stopped,

It's raining,

Man is unhappy,

My heart really hurts. ”
