The senior was stunned and subconsciously said, “Aren’t you in your first year?”


  Xue Xi nodded.

  The senior was still in disbelief. “No, you’re a freshman. How did you optimize it? You haven’t even learned that knowledge, right? Also……”


  Xue Xi said calmly, “Move aside.”


  The senior: “.……”


  Just as he was about to say something, a voice came from the door. “Yu Da is back!”


  “Yu Da is back?”


  The entire computer room instantly cheered.

  The senior could not help but raise his head and look at the door. Xue Xi also looked over and saw Yu Da walking in. His face was swollen and his lips were bruised.

  The moment he entered, he threw his bag aside and wiped his lips before asking, “What’s wrong?”


  The senior immediately said, “What’s wrong with you?”


  “Nothing,” Yu Da said. “I was bitten by a few mice.”


  The senior: “.……”


  Understanding his temper, the senior simply did not ask further. “Hurry up and take a look! Our firewall has been attacked!”


  Yu Da nodded. When his gaze swept past the senior, he coincidentally saw Xue Xi. He frowned and said coldly, “Why are you here?”


  Xue Xi: “?”


  Before he could finish speaking, the senior said, “She’s from the Math Department. She’s here to help. What’s wrong?”


  Yu Da rolled up his sleeves and walked to his seat. He said, “I have a feud with her. Chase her out.”


  Xue Xi: “?”


  Senior: “?”


  The senior could not help but say, “She came to help for free……”


  Yu Da stopped and said, “I’m doing this for free too.”


  The senior: “.……”


  Someone in front turned to look at him and shouted, “Yu Da, come over quickly. I can’t take it anymore! I can’t take it anymore!”


  However, Yu Da stood there and stared fixedly at Xue Xi.

  The senior understood his strange temper. After all, Yu Da was very capable, but his temper was well-known in the department!

  If he did not chase Xue Xi away, Yu Da might really just stand there and allow the firewall to be breached.

  The senior looked at Xue Xi awkwardly.

  Xue Xi raised her eyebrows and looked at Yu Da. She slowly said, “I said that my computer skills are very good.”


  The senior also nodded. “Yes, yes. Just now, this student said that since she can optimize the firewall, she already has a plan! Her computer skills should be pretty good. Let her stay and help!”


  Yu Da sneered. “No matter how good she is, can she be better than me?”


  The senior: “.……”


  Of course not.

  Who in Huaxia University did not know that Yu Da was a rare genius?!

  The senior finally sighed and pleaded, “Yu Da, I’m begging you. At this moment, if this junior can really optimize the firewall, it’ll be our fortune. Don’t throw a tantrum, alright?”


  Yu Da gave his senior some face and snorted. He shot a glance at Xue Xi and sneered. “You’d better keep your word and really optimize the firewall. Otherwise…… I’ll make you suffer!”


  After saying this, Yu Da walked forward and sat in his seat.

  The senior heaved a sigh of relief.

  Just as Yu Da walked over, the senior who was standing up was about to sit down to continue typing when Xue Xi pulled his chair. She then nimbly sat in front of his computer and started typing on the keyboard.

  The senior was a little worried that she would not do well, so he stood behind her and looked over.

  Xue Xi typed the code very quickly. Clearly, she was very familiar with the software they were using. The senior only looked at it for a while before confirming that this junior really knew how to optimize it!

  Just as he was about to continue reading, the teacher in front saw his standing and could not help but shout, “Hurry and help others. Don’t just stand there!”


  When the senior heard this, he could no longer be bothered with Xue Xi.

  After all, the improvement of the firewall could not be immediate. He had to help others resist external attacks!

  Hence, this senior did not realize that after he left, Xue Xi narrowed her eyes and quietly opened another interface to quickly type out the code……

  Yu Da sat in front of the computer with a serious expression.

  His fingers typed quickly on the keyboard, making one’s eyes light up. He casually typed a few times and the person beside him heaved a sigh of relief. “Fortunately, you came in time. I couldn’t hold on for much longer!”


  Yu Da did not speak and continued to mend the loophole to prevent others from attacking again.

  With Yu Da around, everyone heaved a sigh of relief. They could not help but start discussing. “The other party is a single person, right? There are so many of us, but we can’t even resist him. He’s simply too amazing!”


  “I don’t know who it is. I think it’s from overseas.”


  “Why would such a top-notch hacker hack into our school’s intranet? To be honest, there are no secrets on the school’s intranet. It’s just that if it’s hacked, Huaxia University will be very embarrassed.”


  A hundred-year-old university that specialized in nurturing computer talents was actually broken into by a single person. It was simply a great humiliation.

  Just as they were speaking, a voice suddenly sounded. “We’re screwed! His attack is now even more powerful! Hurry!”


  “Oh no, I’ve been attacked!”


  “F*ck, he was just testing us just now. This is the real attack. We can’t defend at all!”


  “We’re screwed, we’re screwed! My place has been broken too!”


  In the tense atmosphere, Yu Da was quickly typing on the keyboard to mend all kinds of loopholes and resist the other party’s attack.

  His expression was solemn.

  The other party’s attack was domineering and sharp. Yu Da had been in the computer industry for many years and had only encountered such pressure when X attacked the school’s surveillance system.

  However, the other party was not X. Every hacker had their own habits.

  This other party was clearly a foreigner, but it made him feel helpless as though a huge flood was about to surge.

  It was as though the power of the other party on the internet was as unstoppable as the power of nature!

  Yu Da typed hard on the keyboard, trying to use his weak body to resist the other party’s invulnerable strength. He clearly knew that this was a futile effort, but he did not retreat.

  His eyes were sharp as he stared at the unstoppable flood. He closed his eyes in despair!

  He originally thought that the internet would be completely paralyzed and controlled.

  Unexpectedly, when he opened his eyes again, an invisible barrier had blocked the flood!

  They were not breached!

  Yu Da was stunned.

  He stared fixedly at the screen and saw that not only did the other party’s attack not slow down, it became even more hurried and overbearing. However, that barrier was firmly rooted there, giving one a sense of security.

  Yes.

  A sense of security.

  Although it seemed to be just a thin layer, it was as though Mother Earth had extended a warm hand and silently isolated all the danger.

  Who was it?

  Who helped them?!

  This gentleness was overbearing, like a mountain…… It was X!

  Hero X!

  Yu Da’s eyes lit up. He, who had long become X’s fan, quickly checked.

  X was currently fighting with a foreign hacker and could not care less about himself.

  It was a good chance for him to take advantage of the situation.

  He did not want to do anything. He just wanted to find out who his idol was.

  He gulped. Although he knew that it was very rude, he still rudely typed on the keyboard and searched for X’s ID. In the end, he realized…… that this ID address…… was in the computer room!

  Yu Da widened his eyes when he saw the address.
