Han Feng actually wanted to change his major, which surprised the people in Door 301. However, since Han Feng had decided, they had no choice. After all, this was Han Feng's business.

Fortunately, even if Han Feng switches to major, he will still stay in this dormitory.

Due to Professor Li Zhongwen’s personal care and the Han Feng counselor felt that he was a thorny and difficult to manage, so he wanted Han Feng to switch to another major. Han Feng’s procedures were quickly completed with their active handling.

Liu Yueshuang didn't know where she heard this news. After class, she found Han Feng and asked about it. After all, changing majors is a major event for students that can affect their future development in life.

In response, Han Feng explained: "Actually, I have always been interested in neuroscience, mainly to understand my body. After all, I have been lying in the hospital bed for more than ten years."

"Then have you asked your godmother and others for your intention?"

"Uh... I haven't told them yet." Han Feng himself didn't think this was a big deal, but he also understood what Liu Yueshuang meant. As a son of human beings, some major events should be told to his parents, although they are likely to support your decision.

"I'll call back later."

"Well, just be fine if you know." Liu Yueshuang knew that Han Feng had his own opinion, so she didn't say much, "By the way, madman, when did you have time to teach other members? They have almost annoyed me these days, and they yelled every day that you didn't see you."

Those members decided to join the computer club, but they were mostly for Han Feng, but recently they held a club event and didn't even see Han Feng's ghost, which made them very dissatisfied. They found Liu Yueshuang and asked Han Feng to teach them.

Han Feng said in a daze: "Class? What class should I take?"

Liu Yueshuang smiled and said, "Don't forget that you are now a technical consultant of the computer company!"

Han Feng Dahan, the so-called technical consultant, had long forgotten that he had gone out of the sky. It was the title that Liu Yueshuang temporarily added last time.

"Xiao Shuangzi, I don't have that much free time. Besides, I can't teach anything."

Han Feng shrugged. He was telling the truth. Others can't learn these things at all. They would never teach them hacking techniques. This is simply impossible.

Liu Yueshuang thought about it and could only sigh: "Hey, they will definitely be dizzy again after the event."

Han Feng couldn't help this.

After saying that, both of them were silent for no reason and walked shoulder to shoulder on the bluestone path by the school lake.

After walking for a while, Liu Yueshuang asked again: "Crazy, I never knew you could draw, nor did I know when you learned it, but he actually drew so well."

Han Feng suddenly stepped forward last time and saved the computer club from the crisis. In addition to being grateful, Liu Yueshuang was more confused in her heart. After holding it in for so long, she finally asked.

Han Feng joked: "You don't know a lot. My secret cannot be understood in a day or two, haha!"

If it were in the past, Liu Yueshuang would definitely have glanced at him again and laughed at him as "smelling and beautiful", but now, she really feels this way.

The last time, she was surprised that he had so much money in his bank card, but she was understanding and did not break the bottom of the casserole. This time, Han Feng was even more outrageous. I don’t know when he actually learned such a skill of drawing. By the way, he also had the ability to play fighting games! Liu Yueshuang later checked online and knew the difficulty of the "Real* Fighting" game. She also learned that Kong Peng was the champion of the Chinese region of the last fighting competition, and Han Feng could actually beat him so hard that he didn’t even have the power to fight back, and he won completely...

Liu Yueshuang felt that she was becoming less and less able to understand Han Feng.

Han Feng didn't want to get involved in this issue, and happened to remember something to tell her, so he stopped and asked, "Xiao Shuangzi, is the computer I used last time yours?"

“Which?”

"It's the notebook I competed with them."

"Oh, that one." Liu Yueshuang said without hesitation, "That's Xiao Lizi's computer." The reason she remembered so clearly was that later, she copied the painting she drew by Han Feng to her hard drive.

"That day I found that the firewall software on her computer was quite special."

When Han Feng saw the firewall, he felt a little intimate, because it was a very old firewall software, which Han Feng saw twenty years ago. The reason why he was so impressed was that this firewall was actually a hacker software, and its code was open source. Everyone can compile it according to their needs, for example, to open the services they need, change a shell, and then send it to the person they want to control. Usually, it claims that this is a security software that a large company has not yet been listed, tricking the other party into installing it, and then he can do whatever he wants.

"Firewall?" Liu Yueshuang was very surprised why Han Feng suddenly noticed this. After thinking for a while, she said, "I remembered that Xiao Lizi told me last time that the firewall seemed to be given to her by Du Shaofeng. I heard that the security performance is very good and can effectively prevent viruses and hackers' attacks. It is the firewall that hackers like to use the most."

Du Shaofeng? Han Feng is a little strange.

Haha, he is really right. It is really a firewall that "hackers" like to use, but the meaning is just reversed.

Han Feng is now sure that Du Shaofeng must have visited the little Lizi's computer many times.

Han Feng was strange, why did Du Shaofeng change his target? Could it be that he retreated due to the difficulties?

Thinking of this, Han Feng continued to ask: "Is that Du Shaofeng still pursuing you?"

Liu Yueshuang was obviously caught off guard by Han Feng's direct question. She was stunned for a moment before quickly saying: "It's not my business whether he pursues me or not. Anyway, every time he asks me, I ignore him. By the way, he seems to be pursuing Xiaolizi recently, and he is giving firewall software and cameras..."

Camera!

Hearing these three words, Han Feng's face darkened: "When did this happen?"

Liu Yueshuang said: "It's about a week ago."

This Du Shaofeng is getting more and more excessive!

Originally, he thought that Du Shaofeng was just a computer novices who were clever in pursuit of Liu Yueshuang, but he didn't expect that his character had reached this point.

Han Feng decided not to hide it and said, "When you go back, you can immediately ask the little lizi to uninstall the firewall. If I read it correctly, it should be a spyware. Through this software, others can easily gain control of the computer. Du Shaofeng asked Xiao Lizi to install this software, obviously the intention is bad! What's even more annoying is that he actually gave her a camera. Think about it yourself, what does this mean."

"Ah?!" Liu Yueshuang was so scared that she couldn't help but scream.

"Crazy, is this...is this true?"

"Is it true? You can check it yourself." Han Feng told Liu Yueshuang a keyword and asked her to search the name of the firewall online using a search engine.

Liu Yueshuang's face also darkened at this moment. She said hatefully: "If Du Shaofeng really did such a shameless thing, I must report this to the school. It would be so hateful!"
