Rule department scholar

"I said it's free!" Zhao Yi said nonchalantly, and quickly put the money in his pocket, "Why do you still have to pay! We are friends, very good friends!"

Lin Xiaoqing gritted her teeth in hatred.

Zhao Hongjuan was talking with the parents next to her. From the corner of her eye, she noticed that her daughter had stuffed the money, and her eyes widened and she became vigilant. "Why do you pay back the money to the male classmate? Isn't it a puppy love?"

"Even if it's a formal relationship, you can't give money to your boyfriend!"

"Women, you must never find a Phoenix man!"

"No, I have to talk about her when I get home..." Zhao Hongjuan made a decision secretly, and paid more attention to that side. Fortunately, nothing happened. The daughter seemed to have conflicts with the other party. With an angry look, his fists were clenched tightly.

This is to beat someone?

Don't be impulsive!

Zhao Hongjuan was a little worried about Zhao Yi.

After the process of the playground of the third-grade assembly is completed, the next step is to hold parent-teacher meetings in each class.

Students can leave early.

At this time, Teacher Sun found out that Zhao Yi's parents were not here, so she quickly found Zhao Yi and asked, "Where are your parents?"

"They all went to work and didn't come."

"Really?" Teacher Sun frowned, "Can't you ask for leave if you go to work? It's such an important thing for your child to enter the third year of high school... How about it, I can find time to visit your home when school starts."

"what?"

"Ah what! Your grades in the second year of high school have declined, and you haven't taken classes seriously recently. You must communicate with your parents..."

"#￥%￥..."

Zhao Yi felt like crying when he heard that, the Tao is one foot tall, and the devil is one foot tall!

Can't hide!

Mr. Sun babbled a lot, stopped and added, "You did a good job in your speech today, I hope you can do what you said, do your best, and try to get into a good university!"

"Oh."

Zhao Yi shrugged his head a little helplessly.

He is not afraid of home visits.

But because of my own affairs, I always feel a little guilty about affecting my parents.

Afternoon break.

Half-day vacations are not easy either.

The third year of high school started in mid-August, and I made up classes for half a month in a row. After the official start of school, there was also a three-week holiday, and the holiday was only one and a half days.

I will spend the rest of my life studying.

Zhao Yi is not worried about continuing to go to school. Going back to school is a novel experience. There are very few opportunities to make up for the shortcomings in life. He just needs a little time to do his own things.

For example, make money.

More than ten years later, life is mediocre, and the economy has always been very tight, but no matter how nervous it is, I am not so poor that I only have a few dollars in my pocket.

This is so bleak!

Zhao Yi dug out the money in his trouser pocket.

A sheet of twenty, the largest, with Lin Xiaoqing's label on it: a picture of a cute and cute magical girl.

Pretty image?

"I'm in high school, and I still like magical girls, it's too childish!"

Zhao Yi made a complaint and put the 20 yuan back into his trouser pocket.

There are five yuan left for one piece and one piece for one piece.

His usual living expenses are five yuan a day, whether it is normal school or holidays.

What can five dollars do?

Eat lunch, drink a bottle of drink...

Gone.

There is a saying that is not good, boys just need to be poor!

Zhao Yi quite agrees with this sentence.

When he was in junior high school, all the extra pocket money he spent was donated to the game hall, and in high school it became an Internet cafe. He is an experienced online game player for more than ten years, and everything started in high school.

Since returning from time travel, Zhao Yi hasn't been to an Internet cafe yet.

But he plans to use a computer.

Preferably free.

So he went to the garment factory where his father worked, and Zhao Zhenxi was a technician in the garment factory.

Technicians sound pretty good. To put it bluntly, they are maintenance workers who are responsible for maintaining machines. The maintenance workers in the factory are very scarce, and the salaries are not bad. They are also equipped with special offices. With the gradual popularization of the Internet, equipment I have a desktop computer for personal office use, but most of the time, the computer is in a rest state.

Zhao Yi went to the factory to find Zhao Zhenxi, and then went directly to his office.

"Why don't you go home? What are you doing in the factory?" Zhao Zhenxi asked with some doubts.

"use computer."

"Playing with the computer?!"

Zhao Zhenxi almost raised his foot and kicked it, but in the end he was still reluctant to do so, and just muttered, "I'm in my third year of high school, it's time to study."

"Half a day off, I will go to class every day after that." Zhao Yi said, "If you want to play computer games, Internet cafes are too expensive! Why don't you give me [-] and I'll go to an Internet cafe?"

Zhao Zhenxi took out his pocket for a long time, and only took out ten yuan. When he was about to pass it to Zhao Yi, he suddenly said, "Okay, don't mess with things in the office, and don't play for too long."

When you're done talking, get your money back.

Zhao Yi hurriedly reached out to take it, quickly put it in his trouser pocket, and said with a smile, "Okay, I see, you can go to work!"

"..."

Zhao Zhenxi wanted to get the money back, but found that there were always people passing by the door, and it seemed a bit embarrassing for the factory to snatch money from the children?

He walked away a little helplessly.

Zhao Yi was the only one left in the office. He bent down and pressed the power button. While waiting, he looked around and noticed a familiar box under the desk. His eyes lit up immediately.

The joy of accident!

unpacking!

Open!

Put the fruit computer on the table, press the power button, and then immediately enter the state.

Prop your elbows on the table.

Rest your chin on your palm.

Close your eyes.

At first, Zhao Yi wanted to find a computer to verify the system vulnerabilities he knew, because some vulnerabilities were discovered later, and the system version when the vulnerability appeared may not be the current version.

later……

Zhao Yi thought of his ability.

"Law of Karma"!

Why do you have to do it if you don't have the ability?

The use of "The Law of Karma" consumes a lot of energy, especially when it involves complicated and unknown questions. Some unknown questions have no answers at all. With a computer in front of you, there will be many more 'clues', and the consumption will naturally decrease.

Now that there is a fruit computer, the consumption will definitely be greatly reduced.

Create a question --

[The current version of the fruit Mac computer, does the following vulnerability exist: On the open source Kerberos authentication system, by implanting code...

...making its software a backdoor into a computer network? 】

[A, exists. 】

[B, does not exist. 】

["Law of Karma"! 】

[Answer: A. 】

Zhao Yi opened his eyes and smiled.

feasible!

Chapter 10 Single young women are not easy to mess with

Even if you know the loopholes in the fruit system, it is not easy to verify the existence of the existing version through practical operation.

Verifying some vulnerabilities requires compiling code to run on a computer.

Some professional software will also be used.

Even if everything is ready, it will take a lot of time and energy.

It is much easier with the assistance of "Law of Karma".

Zhao Yi turned on the system and checked the energy value-[Energy: 87/102. 】

"Consume 15 points!"

acceptable!

Now he has an understanding of "The Law of Karma". Whether the "Law of Karma" can be used and the amount of energy it consumes is related to the 'spread range', 'pointing clues' and 'logical derivation' of the question itself.

The wider the spread of the question, the less effort it takes to get an answer.

For example, what is the river with the widest coverage in the world?

Many people know this question, using the "Law of Karma" to get the correct option requires almost no effort.

'Pointing cues' refer to things that are actually seen, or inherently conditioned.

For example, guessing a person's age.

If you just say the name, you definitely don’t know it, but you can see the person, preferably with your ID card on your body, etc. These are all clear 'clues', and "The Law of Karma" can find out the clues, so as to find out the correct option in the answer.

The last is 'logical derivation'.

It is difficult to find the correct answer to a complex mathematics and physics problem, and few people can solve it. The basic formula is where the logic lies.

If you know the basic formula, you can use the "Law of Cause and Effect" to choose the correct option in the answer according to the formula without consuming much energy.

On the contrary, if you don't even know the basic formulas, you can only trace complex problems with a small amount of 'spread range', so the difficulty is very high.

When a question does not have 'scope of transmission', 'pointing clues' and 'logical derivation' at the same time, "The Law of Cause and Effect" cannot be used to obtain an answer.

The undiscovered loopholes in the fruit system obviously do not have any 'spread range', but the 'pointing clues' are very clear.

For one thing, a fruit computer is in front of him.

Second, Zhao Yi knows the possible loopholes.

Because it is not easy to actually verify, it still takes a lot of energy.

Zhao Yi was very satisfied.

It's pretty good to be able to draw conclusions.

When he was at home before, he asked the same question, and the prompt he got was, "[It needs to consume 41 points of energy, do you want to continue the verification?]"

41 points!

Direct headache!

At that time he chose no.

Now that there is an Apple computer in front of me, the energy consumed is really greatly reduced.

Recharge a little learning currency and turn it into energy.

carry on.
