In a propaganda meeting, the eleven people had their own focus, but without exception, all of them received warm applause from the students.

After the meeting, as soon as Shen Yun got his mobile phone, he called home.

Of course, this time it wasn't on his parents' side.

"Grandma, it's been okay lately. Is Grandpa back? Shen Yun asked the old man very softly, and what he got was his grandmother's gentle care: "Yun'er, how are you doing lately." That dead old man is in the study right now, and I'll call him. ”

There were a few calls on the phone, and soon the phone was picked up again, and Shen Yun's grandfather's strong voice rang: "Shen Yun, why did you call me." What, what's the matter? ”

"I saw you the other day." Shen Yun had mixed feelings in his heart, and finally chose to express it in the simplest words possible.

Hearing Shen Yun's words, the old man was stunned for a moment, and then exclaimed: "A few days ago? You were also in Liao Province at the time? ”

In the exclamation, Shen Yun heard the joy and excitement of the old man. Over the phone, Shen Yun still nodded: "Yes." I used to raise the bar with you when you told those stories, and now I want to say sorry to you. ”

This "I'm sorry" is full of Shen Yun's guilt and apology for the protagonists of those stories.

On the other end of the phone, Shen Yun's grandfather, an old man who has been strong for many years, suddenly shrugged his shoulders, and the corners of his eyes were soaked with tears.

"I know I'm sorry, maybe it's coming late. But I hope you will take it, and then, watching your grandson, march forward in the army to defend your country. ”

Wiping the tears from the corners of his eyes, the old man suddenly laughed: "Good, very good." With your words, I am relieved. You are a sensible child, and you will definitely live up to my expectations of you. ”

The old man didn't continue and hung up. Excited, he turned to look at Grandma Shen Yun, who was standing not far away, and begged with a smile: "Old woman, I'm in a good mood today, or you can give me a whole bottle of wine and let me have a good drink." ”

Shen Yun, who put away the phone, was about to rush to the computer classroom at this time.

Compared with the mathematical modeling competition of the day, the computer technology competition came earlier. In the middle of December, Shen Yun was going to rush to the capital with Teacher Zheng.

Naturally, you need to spend a certain amount of time practicing before the game. With Shen Yun's technique, there was no need to participate in such exercises often, however, at Yang Dedi's request, Shen Yun was actually appointed by Instructor Zheng as his temporary assistant.

Naturally, Shen Yun's affairs became more.

Although they often meet, until now, Yang Dedi is still respectful to Shen Yun.

I have to say that this guy has a strong nerdy atmosphere, and many places like to admit death more seriously. often disagrees with people, but once you meet someone who is really capable, you will put down your arrogance and die to the side.

Walking into the computer classroom, in addition to Yang Dedi, there were also some students who came to watch movies and TV series, or check information on the Internet.

In front of so many people, this guy Yang Dedi actually shouted to Shen Yun very seriously: "Assistant Teacher Shen is good." ”

It's a hornet's nest.

Many people had only seen Shen Yun at that lecture, and they didn't know that Shen Yun, a lieutenant, would actually be a teaching assistant for the course of computer basics. For a while, they all stood up and saluted, which made Shen Yun very helpless and returned the salute again and again.

After everyone was settled, Shen Yun glanced at Yang Dedi angrily. That's when I walked up to him.

"It was already said yesterday, and today we are going to talk about how to remove the traces of the invasion. The core idea, of course, is clear to us, which is nothing more than wiping the mission logs of local and remote broilers. But how to effectively cover up the traces of erasure is a matter of craftsmanship. ”

When it comes to computer technology, Shen Yun's previous depressed mood has also been swept away.

With a computer connected to the Internet in front of him, he is like a fish in water. Discussing with Yang Dedi, Shen Yun kept issuing orders in his hands. Many students were very curious about what the two were talking about, and suddenly found that the projector was actually activated.

In the sound of the curtain drooping, I could only hear the music started by the computer suddenly from the podium, and then everyone realized that their computers were actually a little disobedient.

Of course, Yang Dedi, who was sitting next to Shen Yun, knew what was going on.

It turned out that Shen Yun demonstrated in front of him how to continuously manipulate broilers to remotely control other computers

But that's not the point, because today they're going to talk about how to erase the traces. Doing these things is just preparing for what's next.

One of the students, who was surfing the Internet, suddenly exclaimed: "Oops, why did the computer suddenly jump to the homepage of the school's official website." What the hell is going on here, what about my previous documentation? ”

Looking at Shen Yun and Yang Dedi not far away, the major hurriedly shouted: "Assistant Teacher Shen, come and help me, this manuscript will be used tomorrow." I'm going to have to stay up all night tonight. ”

Shen Yun turned his head and smiled at him: "Don't worry, it's absolutely fine." ”

Turning his head and glancing at Yang Dedi, Shen Yun began to explain: "You can also see clearly, what I finally controlled just now was his computer. His documents were deleted due to the need for intrusion. If I need to clean up the traces now, I'm sure I'm going to have to restore everything from before. ”

In the student's desperate eyes, the computer suddenly went black, and then restarted instantly. However, when the computer screen lit up again, he was surprised to find that several windows suddenly popped up on the screen, including the manuscript he had written earlier.

After doing this step, Shen Yun nodded: "The next step is to clean up the traces." A few small programs were planted in his computer just now, so let's cover them up for now. Then clean up some messy task logs that you clicked on. ”

"Finally, set a few scheduled tasks, and by the way, change the time of setting tasks, okay, so that all traces are basically covered up. Even if you want to find it, it's as difficult as climbing to the sky. ”

Putting down the hand that had been tapping on the keyboard for a long time, Shen Yun turned his head and smiled at Yang De: "Next, I need you to be a hunter and find my backhand who left on another computer before." ”

Seeing that Yang Dedi was like a cat that smelled mice, Shen Yun nodded, got up and walked out of the calculation classroom. As the time got closer and closer, Shen Yun couldn't help but have a lot of expectations for this competition. In the past, he used to compete with others in the dark, but now it is the first time that he is competing on the surface.
