Everyone is paying attention to Bi Sheng's every move, because all the students in the big classroom are curious why mobile phone monitoring is the easiest means of monitoring in Bi Sheng's eyes, and an applied physics class has really been turned into applied science by a senior old professor.

Bi Sheng didn't look at everyone, but just stared at the mobile phone in his hand, looking at the green progress bar under the black screen.

The progress bar runs at a constant speed, 80 percent, 85 percent, 90 percent, 95 percent, and slowly the progress bar runs to 100 percent.

Bi Sheng watched the progress bar run and finished, a smile appeared on the corner of his mouth, and then the green progress bar disappeared, and the black screen turned blue overnight.

The full screen of the mobile phone is blue, and there is a 'blue' word written in the middle position, Bi Sheng lightly clicked the blue word with his finger, and in an instant the mobile phone screen began to change again, becoming an interface of Mumu social software, and at the same time, there are three kinds of chat tool software interfaces such as appointment tryst, secret, etc.

Looking at the information in these software interfaces, Bi Sheng had a smug smile on his face.

"Classmate Ye Tianlong, let me ask you one last time, do you really not believe that I have already heard your information now?" Bi Sheng finally asked warningly.

Ye Tianlong looked at Bi Sheng and said, "If there is a kind, you will come." ”

"You should have three kinds of social chat tools pre-installed in your phone, Mu Mu, there are secrets about the tryst, I'm right!"

Hearing Bi Sheng say this, Ye Tianlong's eyes flashed left and right, as if he was observing other people's reactions to him.

"What do these three types of software say? Which boy doesn't install it? I don't believe you don't install. Ye Tianlong said.

"Anyone can install it, but the information I listen to is related to your three chat logs, if you don't believe it, I can read a few messages at will." Bi Sheng looked at Ye Tianlong with a smile on his face.

When Ye Tianlong heard this, he looked a little nervous, as if he was afraid, but he couldn't lose his shelf.

"I think you're pretending to be a fox!" Ye Tianlong sat in the last struggle, still refusing to believe that what Bi Sheng said was true.

"This recorded message is a bit long, it was when you were a freshman, the time was four o'clock in the afternoon on Friday, September 8, 2049 in the Qin calendar, a girl with a nickname called Mango, it seems that he should have said to you first, the first sentence was, 'You are a freshman! I'm a sophomore, is it time for a while? Let's go shopping with my sister! And you reply, 'Is that good?' I've only known you for two hours. After Bi Sheng finished speaking, he looked at Ye Tianlong lightly.

As soon as Bi Sheng's words fell, everyone was looking at Ye Tianlong, and then at Bi Sheng.

At this time, Ye Tianlong looked a little panicked, because it was indeed when he was just in his freshman year of military training, he accidentally helped a senior sister, and then left each other's contact information, a casual encounter.

Ye Tianlong looked at Bi Sheng, speechless for a long time, but still showed some dissatisfaction, and said quibly: "That's not me at all, you are just fooling." ”

Bi Sheng looked at Ye Tianlong struggling weakly, and then said, "If I break blindly, then okay!" At 3:40 p.m. on October 9, 2050, the message you had on the appointment tryst was a girl named Chu Chu Lori, and this time it seemed that you took the initiative to say, 'Do you have time?' See you in the old place, don't see you or disperse', 2051, that is, on October 26 this year, at 2:50 p.m., a girl called the royal sister attacked, he said: 'After class, you come to Bathton to pick me up, GreenTree Inn 3307 will not be gone', how about you still use me to say down? ”

When Bi Sheng finished speaking, the whole classroom was silent, everyone was looking at Bi Sheng with fear on their faces, only Li Yun and Tian Jibai looked at Bi Sheng with ordinary eyes.

All the students in the classroom began to take out their mobile phones, looking at their mobile phones, in their eyes Bi Sheng was simply a monster, in front of it there was no secret in his mobile phone at all, they were all panicked.

Ye Tianlong looked at Bi Sheng with a dull expression, because his ulterior * became an open secret in front of his arrogance.

Ye Tianlong looked at Bi Sheng, a little depressed, this kind of thing would not be calm on anyone's body.

At this time, Tian Jibai looked at the students under Bi Sheng's ability, and they were all panicked.

"This is the practical effect of electronic monitoring, so applied science is a very practical application, we are not staying in theory, it is put into practice, it seems impossible, but it does happen. Bi Sheng's classic case is actually the simplest, in fact, many of the electronic devices used around us are very dangerous, can anyone explain it? Tian Jibai looked at all the students holding their mobile phones in a panic in front of Bi Sheng, and his expression was sluggish, so he said to everyone in a round.

At this time, Li Yun glanced at Tian Jibai, and then raised his hand to signal.

"Li Yun, okay, let's tell everyone about it!" Tian Jibai said.

Li Yun stood up, then looked at all the panicked classmates and said, "The reason why Bi Sheng was able to know the private information in Ye Tianlong's mobile phone was because the mobile phone CPU chip caused Ye Tianlong to leak the secret. ”

After listening to Li Yun's words, all the students focused their attention on Li Yun again.

"Li Yun, how could the mobile phone CPU chip be leaked? Isn't that all CPU chips going to be leaked! A tall, lanky boy said from the back row of seats.

It may be because after Li Yun's transformation, the performance of various bull breaks, coupled with the reversal in the Chinese department, everyone began to slowly notice this student who had no bright spots in college for three years.

Li Yun glanced back lightly, and vaguely remembered that the tall and thin man was called Gu Dexuan.

"Gu Dexuan, what you said is not wrong. According to common sense, we generally believe that the electronic devices we use will not leak my private information, and the reason for leaking secrets is basically that computer hackers implant viruses to steal information, but in fact, it is not, and it is a very serious misunderstanding. Li Yun looked at Gu Dexuan and said.

"We are all studying applied science, and we will pay attention to this aspect in the future. As we all know, all mobile phone chips are based on the ARM architecture for independent research and design, that is, ARM dominates the current smartphone CPU market, but ARM itself does not produce CPU chips, they develop a new core architecture processor design scheme, and then authorize it to other companies to use, such as China's Daoxiang, Huawei, South Korea's Sanxing, the United States' Pinguo, these chip design and manufacturing companies will be ARM provided CP and GPU, communication baseband and other modules combined or reorganized, and the memory particles packaged together, constitute the core SOC of the mobile phone, that is to say, these chip manufacturing companies will implant memory particles with listenable on the structure of the chip in the process of chip manufacturing, so that it plays the function of monitoring the mobile phone, of course, the original motive of these mobile phone companies is to monitor the use of mobile phones, but if it is used by hackers, it will really become leakage and monitoring. Li Yun said clearly.
