Rule system

One o'clock.

Li Jiandong opened his eyes dimly. He had been half-asleep and half-awake, and felt uneasy, so he quickly got up and looked at the computer.

The webpage has been changed again!

It's the eagle again!

It's DJ soundtrack again!

"How did this Yiying do it!" Li Jiandong felt like he was going crazy, his face was scary, and his sleepiness was completely gone. He quickly opened the source code file and found that the database could not be overwritten and could not be modified directly. .

He simply stared at the math problem.

Look carefully!

Look again!

Mathematical problems with high levels of Mathematical Olympiad in high school are definitely not something ordinary people can do.

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

He wrote down Sun Liang's cell phone number.

"Fortunately, I'm clever!" Li Jiandong took a deep breath, thinking that it was too late, wouldn't it be too good to call him?

Can't manage that much, we must solve it quickly!

If it has not been resolved by the morning, Director Zhou will not be able to explain it, but it does not matter if a few people see it. They are not sure whether it was invaded, and they can say something to the outside world, maybe it is temporary adjustment, modification, or just showing an error. What?

Li Jiandong called immediately.

Sun Liang was falling asleep in a daze. Hearing the vibration of the phone, he closed his eyes and touched for a long time. He found an unknown number in front of him. Out of curiosity, he pressed the answer button and heard the opposite saying, "Is this classmate Sun Liang? I was Officer Li who was looking for you at noon yesterday."

"Sergeant Li... OK?"

Sun Liang suddenly became energetic.

Li Jiandong was silent for a long time, not knowing how to speak, and he said seriously, "I'm really sorry to disturb you so late, classmate Sun Liang, I have an urgent matter. There is a math problem, you can help me do it again? "

Sun Liang immediately sat up. He turned on the lamp and asked, "Is it counted as overtime at this night? How much?"

"One hundred, all right? Two times."

"No way."

Sun Liang remembered Zhao Yi’s words, and immediately shook his head, “It’s fifty during the day, and you bother me to sleep, and then I get up to do the questions. I’m not energetic in class tomorrow, and it’s delayed my study for a day! Maybe it’s because of this day, my college entrance examination Can't get into the ideal university?"

"Let's do it! Five hundred, no second price! I'll hang up if you don't agree."

Li Jiandong was dumbfounded.

He deducts insurance and money a month, plus the bonus for full attendance is only about 3,000 yuan.Five hundred when you speak?

This is too dark!

Li Jiandong took a deep breath, resisting his anger and agreed to come down.

Sun Liang felt that he could still bargain, but he didn’t expect the other party to really agree. He still didn’t believe it, so he continued, “In this way, you send me a text message and say, “You’re sure to pay me 500 yuan to thank me for helping. You do the question', otherwise, what if you go back and don't give it?"

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

His character was suspected by a high school student, and Li Jiandong suffered a second hit in his mind. He still humiliatedly agreed.

Li Jiandong took a screenshot of the topic and sent a MMS message. Because of the network transmission speed, Sun Liang waited for a long time to open it successfully. He was also curious about the difficulty of the math problem of '500 yuan'.

Open it and take a look.

"Isn't this the Olympiad question done at noon yesterday?"

Sun Liang looked at the subject in surprise, thinking about the'complex situation of Zhao Yi and Police Officer Li', and finally shook his head simply, "It must be related to Zhao Yi, yes, it will be given to Zhao Yi two hundred and five tomorrow. Maybe next time, Officer Li, It will cost a thousand yuan to buy the answer!"

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

Li Jiandong looked at the information in surprise.

So fast?

If the memory of going to school is not wrong, the difficulty of the question must be very high, how can you do it so fast?

"Really what my colleagues said, is Sun Liang a math genius?" Li Jiandong suddenly found himself unable to understand how powerful Xueba is.

He verified the answer.

correct!

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

After all the modifications were completed, he was worried that there was a problem with his computer, so he simply went to the nearby department, found a new computer, and modified the management entry, ID and password.

"It must be no problem this time!"

"Even if there is a problem with my computer, other people's computers cannot have problems!"

This time Li Jiandong slept very peacefully.

He doesn't know where the specific problem is, but even a high-level hacker cannot stay in front of the computer all the time, let alone crack the login entry, account number and password in a short time.

Li Jiandong was woken up by the phone.

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

"Still Yiying!"

"Hurry up and take a look!"

Li Jiandong thought it was a dream. He only changed the website after three o'clock, and he felt that he had just gone to bed. Someone said that the website was hacked again?

This is too fast!

When he turned on the computer to check again, he found that the news picture was still the Eagle Flash. Clicking in to connect was still the a cappella. The only difference was...

Changed the math problem?

...

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

He said excitedly and vigorously, "Zhao Yi, the police officer Li is looking for me again, at one o'clock in the evening. I slept in a daze, so he asked me to solve the problem. This time I asked for 500 yuan!"

"When I get the money, I'll divide you half."

"By the way, you show your spirit." Sun Liang approached flatly, "Let the officer Li find me again, this matter must have something to do with you, right?"

"Count you clever!"

Zhao Yi said with satisfaction, "It depends on the situation."

The Olympiad is approaching.

Zhao Yi and Sun Liang spent a lot of time on Mathematical Olympiad problems. They had no special training in Mathematical Olympiad. They could only improve by doing the questions. They saw more question types and learned more about the ideas for solving problems. It will definitely help the competition.

Niu Lianhua pays more attention to them than them. She not only supervises the two people to do the questions, but also cares about the questions they have done, and finds new types of questions for them to do.

At noon, she especially came to see and urged 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. After meeting his parents on the roadside, he went to see the houses in two communities near the park.

Liu Jing and Zhao Zhenxi were optimistic about the two houses, and could not 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 was an 11-storey residential building with only one household. The house is on the sixth floor, 170 square meters, with three bedrooms and two halls. It is large in size and the decoration is very general.

He is not satisfied.

Then I went to see the second one.

When he reached the gate of the community, Zhao Yi glanced around and was a little surprised, "Where is Lin Xiaoqing's community?"

It's normal to think about it.

There are several communities near Phoenix Bay Park in the city center. The newly opened commercial houses sell small square meters of high-rise buildings, or old broken communities, which can have large square meters and villa buildings. More than three.

Zhao Yi followed the agent and ran into an acquaintance on the road.

Lin Xudong.

Lin Xudong was walking forward with the phone, and greeted Zhao Yi from a distance.

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

Lin Xudong came over with a little surprise. He only met Liu Jing and Zhao Zhenxi. He hadn't really spoken. It was the parents of the students who met him, and he must say something.

Several people exchanged greetings.

Lin Xudong had a rare day of leisure, and he had explained everything at work. He went home for dinner at noon, but the phone still couldn’t stop. Hearing that Zhao Yi was looking at the house, he left in no hurry, and greeted him warmly. , Said to help out together to inspect the house.

The house they looked at was a front-row villa building with three floors and four households in one building.

Each household has two floors.

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

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

"This house is pretty good. It's only been three years, and it's definitely no problem with the decoration."

Lin Xudong said a few people and went in.

The internal structure of the house is the same as that of Lin Xiaoqing's house. It has a large area on the upper and lower floors. The decoration is indeed like Lin Xudong said. It is really very good. It is not the golden and rich style. On the contrary, it is small and fresh and a little scholarly. The materials are absolutely exquisite, the furniture looks the same as new, and the electrical equipment is also complete.

If you buy the whole set, you don’t even need to buy new furniture and electrical appliances.

Zhao Yi is very satisfied.

He stood by the window looking at the scenery outside, smiled at the corner of his mouth, and communicated with his mother in a low voice, "Very good, this is it!"

"It's set!" Liu Jing asked.

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

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

Lin Xudong came over and said, "By the way, Zhao Yi, your parents were there just now. I can't say, it's a matter of police affairs. You have time to write a report on the security breach. Don't pay too much attention to the format, but where is the main reason? There are loopholes and problems. Your name has already been reported, and the bonus will come down after a while."

"Don't worry, money is indispensable, I'll stare at you."

"Yes, thank you Uncle Lin."

Zhao Yi was really sad.

It’s so interesting to put up a math problem every day. Sun Liang even divided the money into half of the money. He then implanted the program code in the website. It didn’t take time to modify the website. He just waited to keep putting the questions every day.

Is this done?

Lin Xudong 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 the police all know the name of'Yi Ying', you are very good at logistics The group of people here is very shameless."

"but……"

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

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

Qingqing's bedroom?

"IC!!"

Lin Xudong couldn't help squirting a dirty word, his wide-eyed eyes took a fierce breath, the smile on his face disappeared suddenly, but he looked at Zhao Yi with vigilant eyes, but he didn't say anything for a long time.

"I have something to go."

He left a sentence and hurried away.

Zhao Yi looked at Lin Xudong strangely, completely ignorant of what was going on, "I guess he remembered something? The police are really busy."

He leisurely continued to look out the window.

Lin Xudong hurried back home, and the first sentence he encountered Zhao Hongjuan was, "Juan'er, hurry up! Change the curtains for Qingqing's bedroom! I want something opaque!"

"let me tell you!"

"That kid Zhao Yi, he actually wants to buy Wang Enming's house." Lin Xudong pointed out the window in a panic, "Have you seen it? That's the place, I think, he is here for Qingqing!"

"What are you in a hurry?"

Zhao Hongjuan didn't understand, "I see, Zhao Yi's child is very good, he studies well, and can make money. He only got a million bonus in high school. If he can buy a house here for Qingqing... It’s pretty romantic."

"What is romance? How old is Qingqing? You don't know that day, two children were in the living room..."

Lin Xudong became anxious all at once.

"what happened?"

Lin Xudong still didn't say anything, he gritted his teeth fiercely, "Qingqing is still too young to 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 best These young people, he guessed that the telescope is ready..."

Zhao Hongjuan sipped disdainfully, "You! Return to the police! My heart is so dark."

at the same time.

The people in the police logistics office are going crazy.

In the morning, people in police affairs knew that the website was hacked again. Zhou Hongwen immediately lost his temper and couldn't cover the matter anymore, so he just went through the process and reported it.

He called Li Jiandong to yell at him.

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

what happened?

Is it impossible to change a webpage?

The logistics office is really ashamed!

When Zhou Hongwen asked, he realized that it was because of a math problem that'Yi Ying' did not do too much. He left a back door for web page modification, which was a very difficult math problem.

Not only was Li Jiandong unable to do it, but he couldn't find the topic on the Internet. He posted the topic to the group, but no one paid any attention.

People in the police department are not good at doing math problems.

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

It becomes this scene in the office--

"Son, can you do it?"

"Look at the question, it's very important, the task under leadership!"

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

"Don't you just go to high school? This is the high school problem! People can do it, you can't do it!"

one hour later.

Zhou Hongwen held the book with the title in his hand and patted Li Jiandong on the face, "I don't care what you use, today, I must solve him!"

Li Jiandong could only bite his face, and once again came to the gate of No. 13 Middle School.

He squatted on the side of the road and waited.

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

The cold wind blew.

A young man with yellow hair walked over with a horoscope, his ears stuffed with headphones, and his mouth sang affectionately--

"...

The tears can no longer stop,

It's raining,

People are unhappy,

My heart is really hurt."
