After Zhu Zhonghua finished speaking, he picked up the telephone receiver, then stuffed the whistle into his mouth and blew it into the microphone. Pen, fun, pavilion www. biquge。 info

Then he reached out and dialed a number, and after a few beeps, the phone was connected, and a stranger's voice came from inside: "Hello, this is the Beijing Hotel, what can I do for you?" ”

Liu Fang was really dumbfounded, his eyes widened, and he said with a shocked expression: "This ...... This...... How is this possible?! ”

Zhu Zhonghua was very satisfied with Liu Fang's reaction, he smiled and hung up the phone, "You can speculate for yourself first, what is the principle of this?" ”

Liu Fang immediately turned his brain to think, and after a while, his eyes lit up: "Could it be that the invasion was achieved through the audio emitted by the whistle?" ”

Zhu Zhonghua smiled and nodded: "Yes, the whistle in my hand can blow a tone of 2600 hertz, which can allow the telephone system of the telecommunications department to open a telephone call authority, which is a loophole in the telephone system, which the United States has long patched, but it still works in China, because China's technical indicators lag behind the United States." ”

Liu Fangwu felt very shocked: "You can actually find such a covert method, you are really amazing!" ”

Zhu Zhonghua shook his head: "This is not my masterpiece, when I went back to the United States a few years ago, I communicated with a few old friends, and one of them told me that the discoverer was also a hacker, and I won't say who it is." ”

Zhu Zhonghua said this: "Liu Fang, I know you are very smart, but smart is just your innate advantage over others, if you really want to transform this advantage into actual results, you need to be vigilant at all times, because you are not the only smart person in the world, don't look at so many famous hackers in the world, but in fact, really powerful hackers don't like to be in the limelight, technology is their pursuit, don't learn a little technology to think that you are invincible in the world, the reason why you are invincible in the world, That's because the more powerful people don't bother to show their heads, but it's those half-buckets of water that like to swagger around. ”

"Thank you grandpa for your teachings, I will definitely remember it."

"That's good, you have learned radio technology, computer technology is also very good, this is very similar to me back then, in my opinion, your starting point is very high, because the computer will inevitably enter the wireless era, the Americans have carried out relevant research, only people who understand both radio technology and computer technology, can stand at the top of the computer world."

Liu Fang agrees with this: "Grandpa's words are very incisive, I still have a long way to go, and then I want to follow Grandpa to learn hard until you recognize my skills." ”

Zhu Zhonghua nodded with satisfaction: "It's good that you have this perseverance, to be honest, what I'm most worried about is that you are proud and complacent, after all, you are a genius, and it is normal to be proud, but if you are too proud, it will not be good, I want to ask you now, do you have any plans for your future?" ”

Liu Fang was curious: "Why are you asking this question?" ”

"Because you are now a genius mathematician, it is foreseeable that many things will soon come your way, and I fear that you will be distracted by this."

"You can rest assured, I am most interested in computers, as for the title of genius mathematician, I am not uncommon, the reason why I study mathematics is also to improve my knowledge reserves, in the final analysis, it is for computer services."

"Well, that's good, you can accurately position your target, so that you won't end up from a genius to a mediocre talent because you dabble too much."

The rest of the day, the two sat next to a phone booth and exchanged ideas about computers.

As the conversation deepened, Liu Fang admired Zhu Zhonghua more and more, and Zhu Zhonghua became more and more satisfied with Liu Fang.

Principal Zhang is looking for Liu Fang all over the world, and he wants Liu Fang to participate in the banquet in the evening.

After Zhu Zhonghua saw Principal Zhang's figure, he immediately pulled Liu Fang towards the basement, and he sighed in his heart: I hope that Liu Fang, this child, can keep his heart, if there are too many mundane things, he is very likely to be high or low in the future.

Zhu Zhonghua grew up in the United States, and has traveled outside for so many years, what he has seen and heard is naturally extraordinary. He has seen a lot of talented college students, but these people are all unknown in the end, and the reason is that the temptation of society is too great. And the smarter the person, the more pretentious he is, and the more things he dabbles in, so that geniuses often end up becoming mediocre.

On the other hand, those who are not very talented, such as Zhu Zhonghua himself, tend to work unswervingly towards a goal. Even if the talent is not as good as those smart people, but after years of hard work, the achievement will surpass these smart people.

However, thinking of Liu Fang's performance at the International Mathematical Symposium today, Zhu Zhonghua had different thoughts about it: Well, this child's IQ is too terrifying, maybe ...... He's going to be an exception, right?

"Grandpa, there's something I want you to see."

After the two walked into the basement, Liu Fang took out a computer hard drive from his satchel.

Liu Fang has a habit of carrying things that he thinks are very important. For example, banknotes, Liu Fang carries them with him every day.

The computer hard drive he pulled out now was very important to him, because it contained the system software and fool viruses he had written. Liu Fang wanted Zhu Zhonghua to help him check his current works of the highest level and see what was worth improving.

Zhu Zhonghua looked at the hard disk in Liu Fang's hand and said in surprise: "Where did you get this hard drive?" ”

Liu Fang said embarrassedly: "It was removed from someone else's computer when I was secretly learning computers in the past, and there are two works that I spent several months writing inside. ”

Zhu Zhonghua immediately became intrigued, he took the hard drive, and began to work on his computer.

"I've seen the program you wrote in the computer contest before, and if I'm not mistaken, it must have been converted from a very advanced mathematical formula, right?"

"Grandpa is so powerful, he can see through the essence at a glance."

"To be honest, the first time I saw the program you wrote, I was shocked, and even I could only do it to the same extent as you did."

Liu Fang was a little puzzled by this sentence: "In that case, why did you say that when I wrote the program later, you said that my knowledge accumulation was not enough to be suitable for this work?" ”

Zhu Zhonghua smiled: "The answer is very simple, because you have already gotten into the horns of the bull, and your understanding of the program has fallen into a very narrow situation. ”

Liu Fang's eyes widened: "Narrow-minded? ”
