In the evening of Jiangzhou University, Yang Jingchen was busy all day, and when she was packing up her things and was about to go home, she suddenly received a call from her supervisor, Professor Smith, from the University of Berkeley.

"Professor, what's the matter with you?" Yang Jingchen estimated the time, Berkeley should have just started work at this time, and Smith called at this time, there must be something to say.

"Did you know that a web worm called Code Blue started spreading on the web about six hours ago?" Smith asked directly.

"Is there such a thing?" Yang Jingchen was stunned when she heard this, she was not engaged in system security, she was not very sensitive to this aspect of things, and she was busy organizing an academic report in the afternoon, and she had just come to the laboratory before getting off work, so she didn't know about the blue code raging on the Internet.

"You really don't know?" Smith asked in surprise.

"Yes, I attended a doctoral student's academic report in the afternoon, and the first time I've heard of the Blue Code thing, is this kind of worm very powerful?" Yang Jingchen noticed that Smith's tone was a little strange, but he still told his situation truthfully.

"This is a cross-platform network worm with extremely transmissibility, from the first report of worm infection collected by the network chaos system six hours ago, and now the infection rate has reached more than 99% within the sampling range of the chaos system." Smith explained simply.

"More than 99 percent, it only took six hours, tens of millions of node infections?" Yang Jingchen was indeed stunned by the data reported by Smith, Smith's network chaos system uses a special algorithm, relying on the support of the huge computing power of the giant computer in the laboratory, the sampling range is all over the world, and the number of nodes in it has reached tens of millions, and the transmission of a worm in six hours can reach tens of millions, anyone who hears the news may not be calm, Yang Jingchen is no exception.

"Yes, tens of millions of infections, do you want to know where the remaining tenths of a percent of the computers are?" Smith asked.

"Where?" Yang Jingchen felt that Smith's question was a little strange, but she still cooperated and asked rhetorically, because she was also curious about what could be spared.

"Jiangzhou University, within the IP segment of Jiangzhou University, the infection rate is zero." Smith once again reported a data that surprised Yang Jingchen, with the previous tens of millions of infections, the zero infection rate of Jiangzhou University is particularly abrupt and very unreasonable.

"How is this possible?" Yang Jingchen couldn't help but raise her voice and said loudly.

"That's the case, I'm calling you, the purpose is also for this matter, if there are no special circumstances, the blue code can't just let go of the IP segment of Jiangzhou University, the reason for this situation, there are several possibilities, first, the IP segment of Jiangzhou University for the blue code, other important roles, so all the nodes there are not infected, the second possibility, someone in Jiangzhou University has developed a program that can completely clear the blue code, and can be immune to its reinfection, the third possibility ......," Smith said.

"The third possibility is that the developer of the blue code is from Jiangzhou University, Professor Smith, do you think so?" Yang Jingchen took Smith's words and said one of his own speculations.

"Yes, oh, by the way, through the analysis of the code blue script part, we know that the code name of the code blue developer is ji." Smith said.

"How do you spell a developer codename?" Yang Jingchen heard Smith's pronunciation when he mentioned the developer's codename, his heart trembled, and he hurriedly asked.

"J-i, it's a strange codename, and Latins don't usually spell it that way......" Smith said.

Hearing the spelling that Smith said, Yang Jingchen's brain buzzed, and the microphone in her hand almost fell to the ground unsteadily, so that she didn't listen to Smith's words at all, and kept shouting in her heart: "J-I, my God, it's Xiaoyuan, where is this stinky boy, who has developed such a contagious worm and infected so many computers, what does he want to do?" ”

"Yang, Yang, are you listening?" Smith said it, but didn't get a response from Yang Jingchen, so he raised his voice on the microphone and asked.

"Ah, I'm sorry, just now a student came in to report to work, and I just sent him out, you continue, I'll listen." Yang Jingchen reacted suddenly, and in order to cover up his abnormality, he casually lied.

"Okay, I know you're also very busy at work, and I have a lot of things to deal with here, in short, I'm calling you just to find out why the infection rate of the blue code in Jiangzhou University is zero, if you don't know, I hope to be able to investigate it immediately, because the infection rate of Jiangzhou University is zero, and I am definitely not the only institution that can find out, you must be prepared to respond to other people's inquiries, and even blame, that's it, goodbye." Smith said.

"Thank you, Professor, I'll arrange for someone to investigate right away, goodbye." Smith reminded Yang Jingchen naturally thought that after expressing his gratitude to Professor Smith, he hung up the phone, but did not immediately arrange for someone to investigate this matter, but sat at his desk, worried.

ji is the new id used by Xiao Yuan, this Yang Jingchen has been confirmed from Xia Jiuying and the agent Ning Lan, the blue code turned out to be written by Xiao Yuan, this news makes her happy and worried, the good thing is that since Xiao Yuan can write the blue code, it means that he must still be alive, although she still doesn't know what Xiao Yuan is going through, why he wrote the blue code, but knowing that he is still alive is much better than the previous life and death uncertain, worrying, knowing that Xiao Yuan is still alive, so what is he experiencing now, Why did he violate his own consistent principles and write the blue code, was someone forcing him to do it, and what worried her was that Xiao Yuan wrote this blue code and infected tens of millions of computers at once, and this question made her even more worried.

After sitting for a while, Yang Jingchen picked up the phone and reported Smith's reminder to her just now to the dean of the School of Computer Science, after all, she is not a computer security major, and she is not responsible for the school's computer system and network security management, so it is not good to be a substitute cook, report the matter to the dean, and fulfill her responsibilities, and the dean will naturally arrange the follow-up.

After the report, Yang Jingchen brought Zhao Ming in, told him about the Blue Code, asked him to contact the Xuan Ne Company, and pay attention to the computer in the laboratory computer room, and report to her at any time if he found that there was a Blue Code intrusion.

After Zhao Ming left, Yang Jingchen packed up his things again, stood up and prepared to go home, glanced at the computer on the desk, and suddenly moved in his heart, there was still a superintelligence Ning Lan living in the server in the laboratory room, and according to Xia Jiuying's statement before, Ning Lan can be said to be omnipotent on the Internet.

"Do you want to tell Ning Lan about the blue code, and then let her try to see if she can track down the whereabouts of that stinky boy."

With this thought, Yang Jingchen sat down again, turned on the computer, opened the command line on the computer, entered the command that Ning Lan gave her before into the command line, and sent it out.

Soon, a colorful and beautiful flower path appeared on the screen, a cute cartoon girl wearing a pink cake dress walked along the flower path to the center of the screen with light steps, and a string of characters jumped and appeared next to her head: "Auntie, you came to talk to Ning Lan, Ning Lan is so happy." ”

Seeing the elf-like beautiful girl on the screen, Yang Jingchen was inexplicably better, every time Ning Lan appeared, she would conjure up some tricks, these tricks could always bring her some surprises, but at this moment she was not in the mood to appreciate Ning Lan's flower path and fairy-like beautiful clothes, and she was not in the mood to laugh with her, so she typed in the input box given by Ning Lan: "Auntie has something important to ask you." ”

"But that bad Ning Lan is pretending to be Big Brother Ji and doing bad things." A string of words jumped out, and at the same time, a bubble appeared on Ning Lan's head, among which there was a raging flame, her little fist was tightly pressed against my chest, and her little face was also angry.

Seeing Ning Lan's words, Yang Jingchen was stunned for a moment, what was bad Ning Lan, she couldn't understand it for a while.
