Wang Yufei didn't care about what happened thousands of miles away, and he couldn't care about it.

Anyway, according to Lu Yuxin's statement, the other side will definitely find trouble, so in the end, everyone will find trouble with each other.

Wang Yufei is not too troublesome, especially after having chips in his hand.

After a month of tireless research, Huangtian finally lived up to his wishes......

In fact, the emperor lives up to his wishes, and this sentence is not very reasonable here.

Because it's really difficult to find fault with software and hardware vulnerabilities.

It really takes enough talent to do it.

Fortunately, Wang Yufei is very talented in this area, and he can always get inspiration from the complicated and boring digital language to accurately find the key to the problem.

So the two did not waste more than 20 days of time, and found dozens of large and small vulnerabilities in Intel and AMD chips.

Of course, most of them are innocuous and small loopholes.

It was discovered during the test, and the R&D personnel didn't bother to pay attention to it.

But there are six vulnerabilities that can be fatal.

For example, one of the vulnerabilities is for Intel's 8th and 9th generation chips.

According to Intel's official statement, these two generations of CPUs are specially produced to defend against information security threats, and Wang Yufei discovered a logical loop error hidden in the internal buffer of the CPU.

This vulnerability does not cause user information leakage, but if this vulnerability is exploited, the attack code can be embedded in a web page and downloaded to memory through the network, it can directly cause a computer crash.

Simply put, it's a nightmare that puts your computer in an infinite reboot loop.

Whenever the computer starts to import the three boot files into the memory after the self-test is complete, the CPU will automatically report an error, start the self-protection program, and then the computer will restart.

In general, in this case, the user will only think that the system is crashing and can only choose to redo the system.

Then you will find that using a USB flash drive boot does not redo the system at all.

Because you can't enter the boot mode.

The computer still restarts in a loop until it crashes.

At present, Wang Yufei feels that the only solution is to replace the CPU and then redo the system.

Then return the CPU to the factory and reflash the micro-instructions......

The only pity is that in Wang Yufei's opinion, this loophole probably belongs to the nuclear bomb level, and it really can't be used casually.

Once flooded, it may cause a large area of network paralysis, and it will be difficult to recover for a long time.

This is no longer a hole in the same level of killing a thousand enemies and losing eight hundred, but a loophole at the same level!

But it's also an extremely powerful hole card!

Of course, the other five vulnerabilities have their own merits.

For example, one of the most interesting vulnerabilities that Wang Yufei finds most interesting is that it will allow users to modify the CPU kernel instruction set by themselves when triggered.

To understand this vulnerability, we must first clarify the privilege level when using a computer.

Under normal circumstances, ordinary users, as the owner of the computer, still have low-level permissions even if they log in to the computer as an administrator.

Because the user is the uppermost level of the whole system, the interface is visible, but the permissions are actually very low.

Relative to the user layer is the system kernel layer, which is invisible to this part of the user, but the actual authority is extremely high.

In modern CPU design concepts, the two levels are separated by different weight levels.

This is similar to the feudal society of the past.

The fart people are not qualified to know how happy the life of the rich and the rich is, let alone interfere in the life of the master.

Therefore, it is naturally impossible for users to come into contact with the operations of the kernel layer on a daily basis.

However, Wang Yufei exploited this vulnerability to develop a tool that theoretically allows every user to let their imagination fly and participate in the editing of their own CPU microinstructions.

Of course, the prerequisite requirement is to be proficient in assembly language, the advanced requirement is to understand machine language, and the ultimate requirement is to be proficient in machine language.

Otherwise, it is easy to cause the CPU to crash directly, or produce all kinds of logical errors, and make the computer have a weird temper......

It is especially suitable for local tyrant users who are rich and free and have a bit of a tendency to self-destruct to play as a game.

Of course, once the user layer has access to the core layer, what can be done is of course not as simple as modifying these microinstructions.

......

Happy times are always very short-lived.

After paying the price of nearly one million yuan and more than 20 days, Wang Yufei and Lu Yuxin gained a bunch of loopholes, and it was time to go to the capital.

Huaqing's notice had been received more than 10 days ago.

As expected, Wang Yufei was admitted to Huaqing Bioengineering, which must have been directly spent by Gao Deyuan.

According to Gao Deyuan's phone call, it can be inferred that the old professor directly slapped the table with the professors of the School of Mathematics and the School of Information, and proudly declared that even if he fought with those old men, it would be impossible to let him go.

However, Lu Yuxin was snatched away by the computer science experimental class of Huaqing University.

The computer science experimental class is referred to as the Yao class, which is said to be a high-end teaching class that cannot be recruited with a salary of 200 years.

The level is probably higher than the bioengineering that Wang Yufei is going to study.

However, according to Gao Deyuan's arrangement, Wang Yufei can join his brain-computer interaction laboratory after entering the school, and he has a bright future with the same qualifications.

Of course, neither of them really cared too much about this.

It was not because the school was open that he wanted to go to the capital, but because Ge Lingyue had finally completed the handover of work and could officially take up his new role.

It's a big deal.

Changxiang Technology, which has been lost and has almost no movement, should indeed move.

According to Han Qian's meaning, when Wang Yufei went to report with Lu Yuxin, he wanted Guo Jianfeng to run and send the two children to the capital.

But this time the situation is different, the two are going to deal with the company's affairs.

Wang Yufei still had a bunch of equipment in his room that needed to be mailed to the capital, so he had to give up.

But when two people are together, adults are also relieved.

Not to mention that it is not the first time that Wang Yufei and Lu Yuxin have been to the capital, they still have companies and friends in the capital.

So the night before leaving, Han Qian focused on educating Lu Yuxin that when she was alone with a boy as a girl, she must learn to protect herself.

In short, there is a mother who is the head teacher, and she can always have the heart to endlessly.

Especially Han Qian, who has reached a new height, not only has to worry about her son, but also about her daughter-in-law.

......

The next day, the two booked high-speed rail tickets early in the morning.

Guo Jianfeng drove the car and took five people to the high-speed rail station.

Guo Xiaoyi probably couldn't accept the fact that the two of them were suddenly going to school in the capital.

It's very subversive.

Standing at the high-speed rail station, Guo Xiaoyi even felt that Guo Jianfeng brought Wang Yufei to his home as an elder brother, as if it happened yesterday.

Guo Xiaoyi can even clearly remember Guo Jianfeng telling her that her brother was only in the third grade of primary school, and she was confused and puzzled.

The point of subverting the three views is that an older brother who was only in the third grade of primary school when he took him home was about to go to the most famous university in China after just a year in Star City......

She has already reached the third year of junior high school, so she has to wait until September to go to high school with peace of mind, and wait until three years later to go to Huaqing to continue her studies.

I want to see my brother and sister-in-law, so I can only wait for the winter and summer vacations......

However, the two of them still have a company in the capital, which probably means that even if they return to Star City during the winter and summer vacations, they will not be able to stay for long.

Thinking of this, the little girl cried like a tearful person.

hung on Lu Yuxin's body and refused to let go.

"Okay, Xiaoyi, what are you doing here? Your brother and sister-in-law are going to Huaqing to study, what a good thing? What are you making a fuss about?"

Han Qian said as she spoke, her eyes turned red.

Although she only has a year to get along day and night, after all, she really regards Wang Yufei as her son.

Women are already very sentimental, and seeing their daughters crying like that is also sad for a while.

"I know, woo-woo...... But I just can't bear to let my brother go with my sister-in-law!...... Sister-in-law, you won't be able to remember me when you get to the capital and you're busy......"

"You're stupid! How is it possible! Your brother is so precious to you, my God, do you know that your brother is the most worried about going to the capital! Do you know why he wanted to make a brain-computer interaction chip in the first place? Just because he was afraid of any danger you would encounter, he wanted to make a robot that could interact with your mobile phone to protect you!"

Lu Yuxin whispered in Guo Xiaoyi's ear.

"Huh, really?" Hearing this, Guo Xiaoyi finally held back some tears, and her teary eyes glanced towards Wang Yufei who was standing beside her.

"Of course it's true! And your brother didn't give up. It's just that the conditions in Star City are not suitable, you wait, he will definitely remember you when he arrives in the capital, and he will definitely surprise you. Lu Yuxin continued.

"Really?" Guo Xiaoyi finally stopped crying and glanced at Wang Yufei again.

Wang Yufei nodded affirmatively.

From the bottom of his heart, he is actually quite reluctant to this eccentric sister.

But men's feelings are always very subtle in their expression.

The older you get, the more so, for example, Guo Jianfeng, who has begun to look up at the sky, probably thinking about what kind of expression to use to face this parting scene.

"Then you have to talk and count! Chat with me in the group every day!"

Guo Xiaoyi said aggrievedly, and finally let go of Lu Yuxin, came to Wang Yufei's side, and opened her arms.

The brother and sister hugged briefly.

"Okay, you two come to the station! Feifei take care of Yu Xin all the way, and remember to call home when you settle down in the capital. ”

The girl finally stopped crying, and Guo Jianfeng finally didn't have to look up at the sky to think about life, so he opened his mouth and commanded.

Then after saying goodbye to the two children, Guo Xiaoyi, who turned back three times, returned to the car.

However, Comrade Lao Guo probably got into trouble again because of the last sentence!

As soon as she got into the car, Han Qian, who finally couldn't help but slap her eyes with tears in her eyes, slapped Lao Guo's head again, and said angrily: "I really didn't expect you to be such an old Guo! Are you a father? Why are you so ruthless! You cook today! I don't care!"

"Huh?"

"That's it, punish Dad for cooking for a week! Mom, we don't take him with us when we go out to eat!"

Guo Xiaoyi, who was sitting in the back row, stabbed Guo Xiaoyi's heart fiercely.

......

It's a pity that Wang Yufei didn't know Guo Jianfeng's tragic situation after he left.

If he knew, he would probably be more ruthless before getting in the car, so as not to affect his beloved father.

Along the way, Wang Yufei and Lu Yuxin discussed some of the feelings and discoveries of previous research in the quiet business class.

Time passed quickly, and the two of them had almost just entered the state and had already arrived in the capital.

And this time I returned to Beijing, and the salary was still very high.

A beautiful president with a very high status came to pick up the plane in person.

That's right, it's Ge Lingyue.

In fact, in a sense, many people's success is really not a fluke, but the ability and diligence enough.

Take Ge Lingyue as an example, he just handed over everything yesterday and officially resigned from Apple.

Apple only had time to issue an internal announcement, and the external announcement had not yet been announced on the official website, so she couldn't wait to take office at Changxiang Technology.

Standard workaholic.

I don't want to rest for a day.

Coming to pick up Wang Yufei is also something that has already been said.

After receiving the chairman, signing the contract, and receiving the appointment, she can start to show her strength.

Of course, before officially becoming the CEO of Changxiang Technology, Ge Lingyue also had to work part-time as a driver.

On the way to the company, as the boss, he began to officially talk to Ge Lingyue about the treatment of the CEO.

"Sister Ge, how much is your annual salary at Apple?"

"Do you mean all of them? plus equity incentive dividends?"

"Forget it, let's not talk about it. Let me probably talk about the treatment of Changxiang Technology, after taking office, you can directly get one percent of the shares of Changxiang Technology. In addition, there are one percent of the shares that only have the right to dividends, and it depends on the completion of the year's performance. Back we draw up specific contracts. ”

Wang Yufei said seriously.

"Oh, good!" Ge Lingyue replied dryly.

"The guaranteed annual salary is 10 million, but it is calculated separately according to the performance bonus and performance of the year. In addition, the annual salary is guaranteed to increase by 10% each year. ”

Wang Yufei said again.

"Well, what else, say it all at once?"

"Aren't you bargaining?" asked Wang Yufei.

"If I bargain, what do you give now?"

Ge Lingyue glanced at Wang Yufei: "In your words, I am no longer short of money, what I want to do is to realize the value of life." ”

I have to say that this sentence sounds very comfortable.

After all, even if Wang Yufei is confident, he will not dare to be richer than Apple at this initial stage.

That's really incomparable.

Nearly 100 billion dollars of wealth has been left outside the country alone, and there is probably only one in the world.

Basically, one day's interest can be worth the annual turnover of an ordinary large company with more than 500 employees.

After all, Apple is a super company that can live very well on apple taxes alone.

"But you can fight for the future!" Wang Yufei said.

"There's no need for that, it's a two-way process. If the chairman thinks that I am suitable for this position and can enjoy the technology to take off, even if I want to leave, you must do everything possible to keep me. On the other hand, I can find my next home!"

"It's good, I believe Sister Ge will definitely like to enjoy technology!" Lu Yuxin answered.

It looks like everyone is in a good mood.

......

However, Ge Lingyue's good mood only lasted until he drove the car into the office building where Changxiang Technology was located.

When I really walked into the door with the signboard of enjoying technology, the gap in my heart reached the peak.

Sure enough, it's better to see than to hear!

Looking at the simple ceiling, the simple carpet on the ground, and the workstations next to each other, with more than a dozen kittens, Ge Lingyue began to question in his heart whether he was too easily bewitched?..
