"I'm sorry, there's someone here." Xiao Yuan said to the passenger who wanted to sit down opposite him, that seat belonged to Xia Jiuying, and since he got on the bus, he had been helping her keep that seat, but the carriage was already full, and there were still ten minutes to drive, and the beautiful girl still hadn't appeared.

Yesterday, Xia Jiuying's illness seemed quite terrible, but in fact she recovered quickly, after she was sent to the hospital and hung up the liquid for an hour, her body began to regain her mobility, and the ventilator was also taken off, and at this time, Xia's mother Zhang Chunli got the news and rushed over from the city government.

Although Xiao Yuan had a clear conscience about artificial respiration, when he faced Zhang Chunli, he still had a feeling of being a thief, so when Zhang Chunli asked him to go back to school, although he wanted to stay here and watch Xia Jiuying get better, he still ran away.

Like many men and women who fall in love for the first time, after Xiao Yuan returned to school, he was a little eager to see Xia Jiuying, even if he didn't talk to her, just sat in the back row of the classroom, and occasionally looked up, he would feel a lot more settled, but Xia Jiuying didn't go to school that afternoon, fortunately, Xiao Yuan looked at Xia Jiuying's train ticket when he was in the hospital and knew her seat number, so he kept thinking about meeting him on the train this morning and going to Jiangzhou together.

Woo, the train slowly drove out of Nanzhou Railway Station in a long whistle, but Xia Jiuying did not come.

Whew, Xiao Yuan let out a long breath, feeling stunned in his heart, but there was a faint relief, this relief probably came from worrying that Xia Jiuying would reject him.

At noon, Xiao Yuan walked out of Jiangzhou Railway Station and saw his mother and Lin Ran who were already waiting there at the exit of the station.

Yesterday, Yang Jingchen received a call from his son, saying that he was coming to Jiangzhou, and he had been very excited, so he put down some of the things at hand and drove over to pick him up in person.

"Brother, why did you remember to come to Jiangzhou today?" In the car, Lin Ran and Xiao Yuan walked side by side and sat in the back, asking curiously.

Yang Jingchen, who was driving in front, also pricked up his ears, obviously curious about the reason why Xiao Yuan came to Jiangzhou again.

"I used to have a good relationship with a classmate who had a birthday and invited me over to his birthday party." Xiao Yuan said the reason why he had thought about it earlier.

"Aren't your classmates all in Nanzhou, why did you come to Jiangzhou for your birthday?" Lin Ran asked.

"His parents were transferred to work in Jiangzhou, and he followed." Xiao Yuan explained again.

"Oh." Lin Ran responded, and did not ask any more questions, which made Xiao Yuan secretly relieved.

…………

After having lunch at home, Xiao Yuan returned to his room, locked the door, and sat down next to the computer on the grounds that he was tired from the car all morning and wanted to rest.

Don't fight unprepared battles, in the face of unknown enemies, the more fully prepared, the greater the certainty of victory, Xiao Yuan, as a senior hacker, has experienced countless network intrusions and anti-intrusions in his previous life, and knows this well, so he needs to make some preparations in advance before going to the URL given in the battle book to accept the challenge.

He first spent a certain amount of time researching the software Spyadre, which he had traded for the ring logic lock that night, and carefully read its software instructions.

The author of this software turned out to be Snake Fang, Xiao Yuan was surprised by this discovery from the manual, he knew the name of Snake Fang, but after he really grew up, this person had already washed his hands, quit the world hacker world, and did not appear in the network, but in the hacker world, there are still many legends about him.

Xiao Yuan has always had respect for this predecessor in the hacker world, but he didn't expect that in another time and space where he was reborn, he could get one of his software for the first time when he carried out network activities.

After carefully reading the instruction manual of spyadre, Xiao Yuan felt more and more that the snake tooth was not simple, and Xiao Yuan was amazed by the powerful network address anti-tracking ability of this software, and at the same time, he was secretly glad that if he hadn't hacked into the server of his mother's laboratory that night, if he hadn't used a ring logic lock when setting up the springboard, and the encryption algorithm of the logic lock did not belong to this era, then, he would have been unable to escape the anti-tracking of this software.

However, it was precisely because she successfully resisted the anti-tracking of this software that caused Tang Sa and her subordinates to worship themselves like gods, so that they could easily make the transaction worth one million.

At the same time, Xiao Yuan was also a little puzzled, judging from the strength of spyadre, it is definitely a nuclear bomb-level tool in the hands of snake teeth, and as a hacker, such tools are generally not taken out and sold at will, so, how did Tang Sa get this software? Is Snakefang so poor that he needs to sell his software in exchange for money?

Turning off the software instruction manual, Xiao Yuan has decided that this software will be the most powerful weapon in his hands before he has the conditions and time to write a more handy and powerful anti-tracking software.

After studying spyadre, Xiao Yuan still needs to make some other preparations and write a few tools at hand.

He took out a few floppy disks from his bag, inserted them into the computer floppy drive in turn, and copied some of the things he copied from the school computer room into the computer.

Although the program to be written Xiao Yuan can be written with debug, but debug can only use some of the most basic assembly language, the efficiency of developing some complex software is much lower than the direct use of masm, a few days ago, Xiao Yuan used debug to write software, it is really because he has no available programming tools in his hand, he has to use it, and now he has better development tools, naturally will not use that although powerful, but very primitive tools.

The first thing he wrote was a small program he named bot0, bot0 can automatically spread in the network, and bot0 also has the function of forming a multi-loop logic lock on the infected computer, and remotely accepting Xiao Yuan's commands and executing some simple commands.

In fact, bot0 is an upgraded version of the Trojan program written by Xiao Yuan last time, but the computer in the network invaded by the Trojan last time needs Xiao Yuan to do it manually, and after the intrusion, Xiao Yuan needs to manually configure the ring logic lock, and bot0 not only automates the intrusion process, but also automates the process of forming a ring logic lock.

bot0 is much more complicated than the last Trojan, if you still use debug to write, I'm afraid it will take Xiao Yuan a long time, fortunately, now he has better development tools, and this thing, he has written it more than once in his previous life, and it was masm used at that time, so now it is re-written, it can be said that it is a familiar way, and after a few hours, it was successfully written.

After bot0 is successfully written, he also needs to write a control program to receive bot0's return message and send commands to bot0, when this control program is halfway written, it is already dark, and Lin Ran calls him to eat outside the door.

"Brother, have you been sleeping in your room all afternoon?" Lin Ran went out to play with his classmates in the afternoon, and when he came back, he found that Xiao Yuan had been in the room for an afternoon, so he asked curiously.

"Well, after a week of classes at school, I was quite tired, and I finally had a place to sleep with peace of mind, so of course I had to take a good rest." Xiao Yuan said.

Yang Jingchen listened to Xiao Yuan's words, her face showed a trace of doubt, in the afternoon, she had something to go out, but because her son was still at home, she came back earlier than Lin Ran, after coming back, she once came to Xiao Yuan's room and listened to it for a while, although the sound insulation of the room was very good, but she still vaguely heard the sound of crackling on the keyboard in the room, so she concluded that Xiao Yuan did not tell Lin Ran the truth.

What Xiao Yuan was doing in the room, Yang Jingchen was also very curious, but he didn't ask more.

Dinner was eaten by Yang Jingchen, Xiao Yuan and Lin Ran, Lin Minghan did not come back because of entertainment, after eating, Xiao Yuan accompanied Yang Jingchen and Lin Ran to sit in the living room for a while, and chatted with Yang Jingchen about some things about him and his father over the years, which made Yang Jingchen sigh for a while, and his eyes were red.

During the chat, Xiao Yuan wanted to learn something about her and her father from her mother, but Yang Jingchen also kept silent, so he had to give up.

When he returned to his room again, it was already more than nine o'clock in the evening, Xiao Yuan locked the door, and continued the unfinished programming work in the afternoon, and at a little more than eleven o'clock in the evening, this remote control software was also written by him.

After writing these two tools, Xiao Yuan spent a few more hours writing two very vicious viruses, and after doing all this, it was already early in the morning.

So Xiao Yuan ran bot0 on his imminent computer, let him take his own computer as a starting point, automatically find other computers in the network for propagation, and then run bot0's control software, wait for the computer, and receive the propagation information from bot0.

After doing this, Xiao Yuan turned off the monitor, opened the locked door, and lay down on the bed to sleep.

ps: There are two shifts today, and the second shift will be later, but there will definitely be.
