Ice Engineering University, Bi Sheng Building.

In the big classroom, a group of students listened carefully to the lecture of a professor in the lecture hall, and this professor was Tian Jibai.

Li Yun and Bi Sheng sat together, probably under the influence of Li Yun, Bi Sheng was also listening attentively to the class, without the slightest disturbance from the outside world, and Li Yun's listening status was even more needless to say.

Tian Jibai is a professor after all, and he can use his own methods to make all students majoring in applied science understand.

The applied science major is the key major of the entire science department, and many people want to come in when they squeeze their heads, but the applied science major attaches more importance to the students' grades.

It's all the essence of the condensed, and it's not fake at all.

There are a total of eighty-one students in the applied science major, which means that the elite of the entire science department is here, but some people seem to be nerdy science men.

No one thought that such an outlier like Li Yun would appear among such science men.

Although Tian Jibai is close to the age of the sixtieth year, when he lectures, his voice is like a bell, sonorous and powerful, not at all like the year of the sixtieth year, others may not know why, but Li Yun knows.

"The electronic information I just talked about is the tip of the iceberg in applied physics, that is, one of the applied sciences. Under normal circumstances, electronic surveillance is an act of the government, such as the investigation of fighting crimes, as well as the monitoring of users by the communications department to obtain relevant legal licenses, all of which fall within the scope of electronic information surveillance. All I need to know is how it works. For example, how to use one mobile phone to monitor another mobile phone. Tian Jibai looked at all the students and said.

Li Yun listened carefully, thinking about the truth.

Li Yun looked at Bi Sheng next to him, and Bi Sheng seemed to be thinking about the truth.

After almost a minute, Bi Sheng raised his hand to signal, Tian Jibai looked at Bi Sheng raising his hand, smiled happily, and looked at it: "Bi Sheng, you talk about it." ”

Bi Sheng pushed his glasses and looked around, everyone was looking at Bi Sheng, as if everyone didn't believe that Bi Sheng could answer, because no one knew that Bi Sheng was a famous person in the Qin Kingdom, although all he knew was a code name.

Bi Sheng looked at Li Yun, then at Tian Jibai, and said, "Mobile phone software monitoring is actually very simple, and it is also the lowest level of monitoring. ”

After Bi Sheng finished speaking, everyone looked at Bi Sheng in disbelief.

"Simple, then you can tell me about it! Is it so easy for mobile phones to be spied on? Isn't that where we're all being spied on? A student with a freckles on his nose looked at Bi Sheng and said.

Bi Sheng looked at the freckled man, Ye Tianlong, calmly.

Li Yun looked at Bi Sheng and knew that this Ye Tianlong was definitely going to suffer.

"Ye Tianlong, if you don't believe it, we can do a small verification and you will know how easy it is to be monitored on the mobile phone we use, do you dare?" Bi Sheng looked at Ye Tianlong and said.

Tian Jibai looked at the disagreement between Bi Sheng and Ye Tianlong, he just smiled faintly, and did not stop it, Tian Jibai also wanted to see Bi Sheng's strength.

"If you don't dare, I don't believe you can listen to my phone." Ye Tianlong said unconvinced.

"Okay." Bi Sheng looked at Tian Jibai and said, "Professor, I don't know if we can conduct field experiments in the classroom." ”

Bi Sheng still asked Tian Jibai for instructions very politely.

"Yes, of course, I want to see how good our applied science students are. Let's get started! Tian Jibai said.

With Tian Jibai's permission, Bi Sheng took out his mobile phone, shook it in the air, showed it to all the students, and said: "At this time, a smart phone, I believe that all the students present are using it, it may be dual-core or quad-core, and the application software in it I think everyone also has instant chat software equipped with interactive communication, Ye Tianlong, believe it or not, I can know your chat history in my mobile phone for nearly a month, which is also the result of electronic monitoring, do you believe it?" ”

Ye Tianlong looked at Bi Sheng, with a very disbelieving expression on his face, the mobile phone is here, and the application in his mobile phone, how could Bi Sheng know? Even if you steal your account information, and you still have three layers of secret protection, it is completely impossible to steal.

"I don't believe it." Ye Tianlong was straightforward and said categorically.

Bi Sheng looked at the stubborn Ye Tianlong and smiled helplessly.

Li Yun, who was sitting next to Bi Sheng, didn't look at Bi Sheng and said, "Mushroom, you really know Ye Tianlong's chat information!" ”

"Is that still fake? It's a piece of cake for me. Bi Sheng said proudly.

Li Yun looked at Ye Tianlong, and instantly prayed for Ye Tianlong, something unexpected might happen in a while.

"Since you don't believe me, then we'll get started!" Bi Sheng said.

"Bi Sheng, don't you know Ye Tianlong's mobile phone chat information! It's time to delay and get out of class! A girl with short hair said.

Bi Sheng looked at the short-haired girl and said: "First of all, the chat message belongs to Ye Tianlong's private information, and it cannot be disclosed at will, and his consent is required, as long as he explains that I do not bear any legal responsibility for the stolen information, then I don't care, after all, you people testify to me." ”

Bi Sheng is very familiar with the rules and said.

Tian Jibai looked at Bi Sheng's clothes and said very professionally, with a slight smile on the corner of his mouth, very pleased, as if he was affirming his choice.

Listening to Bi Sheng's words, Li Yun also secretly admired Bi Sheng's professionalism, if he hadn't seen Bi Sheng's ungodly electronic information technology with his own eyes, Li Yun would not have believed it at this time.

"Okay, even if you listen, I want to see how you do it, I, Ye Tianlong, authorize Bi Sheng, and I don't do any legal responsibility." Ye Tianlong said.

When Bi Sheng heard Ye Tianlong say this, he smiled slightly, with a little cuteness, but behind those round eyes were a pair of shrewd eyes.

At this time, Bi Sheng held his mobile phone in his hand and opened an application software inside, the software was not included in the mobile phone app, it should have been installed by Bi Sheng himself in the later stage.

The application software is just a very common software for detecting CPU chips, and when Bi Sheng opened the software, Bi Sheng said: "Ye Tianlong, can you tell me what kind of mobile phone you use?" ”

In fact, Bi Sheng really didn't know what kind of mobile phone Ye Tianlong used.

"Dao wants d830." Ye Tianlong blurted out.

Bi Sheng listened to Ye Tianlong's words, nodded himself, and then entered the brand and model of the mobile phone that Ye Tianlong talked about into the software.

After the software analysis runs for a minute, the software displays the information of the mobile phone's CPU processor chip, and then Bi Sheng smiled, Bi Sheng closed the chip detection software, opened a browser, and then Li Yun casually entered a string of commands, and suddenly entered the internal website of the mobile phone manufacturer Daoxiang Technology Company, stole the relevant information of the D830 CPU chip from its database, and then entered its data acquisition system. Looking at the information about the processing data of the D21 processor used by the D830, Bi Sheng placed the browser in the background, and then opened it, a special application software, and Bi Sheng's mobile phone was displayed as a black screen when entering the software, but Bi Sheng did not have any panic.

I saw Bi Sheng enter a string of commands in the black screen, and after the input was completed, a green progress bar was displayed in the black screen, and the progress bar was gradually running towards 100%.
