Rule system

Until the end of school in the afternoon, Li Jiandong saw Sun Liang walking out. He dragged Sun Liang to find a secret corner, painfully took out a stack of money, and pointed out five cards and handed them over.

Transaction complete!

"Thanks!"

"Officer Li, if you have any questions next time, it's okay to find me and give you a 20% discount!"

Sun Liang took the money and was about to leave, but he didn't expect to be held back by Li Jiandong, "What else?"

"This one……"

Li Jiandong hesitated for a long time before he said, "There is another question. You can help me to do it, right? It was fifty yuan yesterday. Give you forty, okay?"

Sun Liang looked at the question carefully, suppressed the doubts and excitement in his heart, and asked seriously, "Officer Li, do you know what the question is?"

"do not know."

Li Jiandong shook his head, "What do you mean?"

Sun Liang said, "Let’s tell you directly, this is an Olympiad question, even in the Mathematical Olympiad, it also belongs to the difficult category. Do you understand? This kind of question, even if you find a middle school student, I promise, Ninety-nine percent of people can’t do it. Even if they can do it, it will take a lot of time. It’s a great thing to do it one afternoon or one night."

"Then what?" Li Jiandong thought afterwards.

"Forty dollars?"

Sun Liang grinned exaggeratedly and shook his head vigorously, "Police Officer Li, if you want to understand two points, first, the difficulty of this question is higher than that of last night, and second, it’s already past six o'clock and it’s time to get off work. It must be considered overtime."

Li Jiandong understood, "Don't explain it, just say how much it is!"

"one thousand!"

Li Jiandong glared fiercely.

Sun Liang said, "Of course it's not possible. Let's count as friends too. There must be a 20% discount, just 800!"

"Eight hundred? Are you robbing? I tell you, I am the police!"

Li Jiandong almost took out his gun in anger.

Sun Liang shivered with fright, and continued to insist, "What am I afraid of? I am not breaking the law. Don't want to scare people! You pay for knowledge, if you like me! Or go find someone else, or think about it. One way, you come to me at noon tomorrow, so that you don’t work overtime. I’ll give you a 50% discount and 400 yuan will do."

Sun Liang felt that eight hundred was indeed too high, so he still left a back door for himself, thinking about making four hundred at noon tomorrow.

Four hundred will do!

There is no need to think about that question at all.

It took him two hours of brainpower to make it the day before yesterday, and the result was a little wrong. After reading the answer several times, the impression was really too deep.

Li Jiandong couldn't wait for tomorrow. Seeing Sun Liang really wanted to turn around, he immediately said anxiously, "Good, good, good, 800, 800, classmate Sun Liang, I am afraid of you, you are so dark! "

"That's a deal?"

Sun Liang asked with a smile.

"That's a deal."

Li Jiandong nodded vigorously.

"Take the question here, I'll take a look." Sun Liang took the notebook for recording the question, glanced at it to make sure it was the same question, and he already had the answer in his mind.

He took a look at the time, and there was still half an hour to study.

Li Jiandong handed over the pen and asked, "Do you want to count?"

"Officer Li, would you like to give the money first?"

Sun Liang said suddenly.

Li Jiandong looked at him questioningly, "Why?" But he was a policeman himself, confident that no one would lie to him, in order to show his sincerity to'buy the answer', he still took out the money and handed it over.

Sun Liang took the money and put it in his trouser pocket, and took a pen to write on the paper.

He only wrote one line.

then.

He handed the book to Li Jiandong, "Police Officer Li, I'm done. Here you are, this is the answer. I won't tell you anymore, I will go to self-study later."

Sun Liang said and ran away quickly.

Li Jiandong didn't react for a while, and suddenly felt that he had been cheated. He looked at the contents of the book angrily, as if it really was the answer?

Call!

Let a colleague help with verification!

quickly.

The result came out.

"Jiandong, that's okay! This answer is correct, it's unlocked. I found the expert so soon!"

Li Jiandong couldn't laugh at all.

Although he didn't understand Xueba's ability level, the logistic department couldn't solve the math puzzles that he could not solve for a long time. Even a genius would not know the answer at a glance.

Sun Liang, this kid...

I must have done this question!

"correct!"

"He wants to participate in the Olympic Mathematical Olympiad in the province, maybe he happened to do it?"

Li Jiandong found a reason that he could barely accept, but there was always a depression in his heart of being'played'.

...

Sun Liang went back and shared the money with Zhao Yi.

Both of them are very happy.

Sun Liang was so happy that he really made money. He made 400 yuan in one breath. Adding the two hundred and five last night and the 50th hour at noon, he made 700 yuan for doing the questions in two days.

This is a lot of money!

He paid more than half of the prize money for the "Youth Cup" competition and the prize money issued by the school to his family, and he left a thousand yuan. The dinner and the usual expenses have already been spent.

Now I have money again.

The money was earned on his own, and Sun Liang felt very happy.

Zhao Yi is also in a good mood, the amount of money is not important, the way of making money is more interesting.

Pity.

The policing business is over.

"Sorry!"

Zhao Yi patted Sun Liang on the shoulder and sighed, "There will be no such good things in the future!"

The two continued to do Mathematical Olympiad questions.

In the evening self-study classes in elite classes, there will be occasional teacher lectures, but most of the time, the students will study the Mathematical Olympiad together.

The day after tomorrow is the Olympiad.

The Olympiad is held in Jiangzhou. They will take a bus to Jiangzhou tomorrow afternoon. After staying overnight, they will go directly to take the test in the morning.

Now is the last time.

Simultaneously.

In the office of the third year of high school, several teachers on duty were also discussing.

Niu Lianhua is "worrying" about leading the team to participate in the Olympiad competition, "I am a woman, single, and two male students. I went to Jiangzhou to participate in the competition and stayed in a hotel for one night. How could it not be like this!" "

"You say, right?"

Several teachers nodded reluctantly, and they all felt it was no big deal.

Being a young teacher Shen Yan is indeed not very good.

Teacher Shen Yan is young and beautiful, and it is not suitable to go to the remote Jiangzhou with two 18-year-old male students.

Ox Lotus?

"The thing to worry about is the two students..."

Of course.

Regardless of Niulian's own character and appearance, it is indeed unreasonable for women to lead the team to places too far.

Such things are usually done by male teachers.

What Niu Lianhua said was really unexpected, "I suggest letting Teacher Xue follow along!"

Suddenly.

The teachers in the office collectively looked at Xue Pinggui, and Xue Pinggui's face blushed.

"me……!"

Xue Pinggui hesitated for a long time, did not say anything, and did not know whether to agree or disagree.

Xue Pinggui's mentality was really broken, he felt like riding a bull.

It was a lonely night...

He has been single for nearly thirty years, sitting alone on the bedside of his lonely heart, seeing the messages sent on the phone, and not knowing what is going on, his brain thinking is controlled by hormones.

He responded when the mobile phone received a message.

In less than half an hour, he successfully evolved into a matador.

After.

Ashamed and annoyed suddenly came to my heart.

Niu Lianhua still understands him very well, "It's normal if you don't know how to face it. We are colleagues, and we are developing too fast."

"I can understand your feelings. I am a divorced woman."

"It's okay, if you can't accept it, when nothing has happened, we are still colleagues, the same as before."

Xue Pinggui was very comforting, but later things did not develop like this.

Niu Lianhua was obviously different to him.

Becoming enthusiasm in school is only one aspect. There are also various kinds of care in life. Sometimes he buys vegetables to send him. He complains that a big man doesn't know how to take care of himself, so he takes the initiative to help wash clothes, cook, and clean up the house.

until now.

Xue Pinggui didn't know what to do.

Sometimes, he felt that Niu Lianhua was also quite good, but it was a little bit unacceptable and a little more grumpy, and it was a bit embarrassing to stand with her.

The last point is very important.

Xue Pinggui feels awkward whenever he thinks of the look in other people's eyes. It is not a good saying, a woman is the face of a man, and there is a beautiful woman around him that will make a man have face on the street.

On the contrary, it is Niu Lianhua.

It's hard to ride a bull!

Xue Pinggui hesitated and didn't respond. He didn't know how to respond. Maybe it would hurt Niu Lianhua to refuse directly?It doesn't matter if it hurts, the key is that she gets angry and tells the secret of that night...

Cough.

agree?

Tomorrow the whole school, going up to Principal Wang Chengmin, going down to the cafeteria to eat, will know his relationship with Niu Lianhua, otherwise, how to explain a female teacher and ask a male teacher to take the students to Jiangzhou... live together?

That night.

Zhao Yi wrote a police information security report.He is not a police officer, so there is no need to pay attention to the format, just write the content directly.

He mainly wrote about routing issues, but also about poor website security.

He mainly relied on routing and monitoring methods to break the website. The release of the "one-off Trojan" also relied on the monitoring of the Penguin. The important thing about the "one-off Trojan" is the delivery process. The real Trojan horse has little relationship with security.

The security problem of the police website also exists. The construction of the website is too simple. He can think of several ways just to engage in destructive intrusion.

After submitting the question, it has nothing to do with Zhao Yi.

He just focused on Mathematical Olympiad.

Grind the gun!

It must be right to do a few more Mathematical Olympiad questions.

Zhao Yi is also a little nervous. It is the first time to participate in the Olympic Mathematical Olympiad in the province. There are some types of questions that he is completely unsure of.

As long as you can find the direction of thinking, and then use "causal thinking" to grasp the key.

The report submitted by Zhao Yi appeared on the police intranet the next day.

This is where the logistics office is worried.

The reports submitted by the “persons” invited by the police service will surely be seen by everyone. The problem of logistical construction of the website is tantamount to direct exposure.

That's very shameless.

Before, a computer expert invited by the Logistics Department also wrote a security report. The content submitted was mainly related to the hardware security configuration of the police.

This so-called "computer master" did not do anything substantive, and the reports submitted were not regarded as important.

'Yi Ying' is different.

'Yi Ying' has continuously broken the police website, and even the police cleaners know that'Yi Ying' is a truly competent hacker, and many people are interested in'Yi Ying'.

Many people have read the report of "Yi Ying" and saw his description of routing security.

"With only simple monitoring methods, you can get the unencrypted keyboard keyed information, which leads to computers under the same route and the login network accounts are easily stolen..."

Lin Xudong doesn't understand computers. Typing is all about playing the piano with one finger. To him, the technical term for computers is like a heavenly book.

However, he stared at this sentence carefully and carefully, and then remembered the strange things that night, his mind suddenly opened up.

"I said the Penguin was stolen!"

"I thought it was a Trojan horse, virus or something... So it was you!"

"Yi! Eagle!"
