Mark's request surprised Xiao Yuan a little, but after a little thought, he seemed to understand why he wanted to play memory competition with himself.

"Okay, let's do it tonight, there's plenty of time in the evening." Xiao Yuan said.

"Okay, but I suggest you start writing now, or you'll lose in the evening." Mark said.

"Also, I've plugged the exploit in the operating system you found last time, but I hope you can find other vulnerabilities and start with that, otherwise your chances of winning will be slim." Mark said again.

"Heh, I'll do my best." Xiao Yuan smiled and said.

Mark saw that Xiao Yuan agreed, stopped talking, turned back to his seat, and buried himself in work again, Xiao Yuan smiled, turned on the computer in front of him, and wanted to familiarize himself with the system and environment of this computer.

"Xiao Yuan, Mark is not Han Xiaoyu, if you want to win him, it's not easy." Jessica said when Xiao Yuan was familiar with the computer.

"Thanks for the reminder." Xiao Yuan smiled at Jessica and said.

"It's okay, we're a group now, if you don't mind, I'd like to have a game with Mark first, so you can get to know Mark's personality, and it's so targeted when programming." Jessica said.

"Of course I don't mind, it's up to Mark to be willing." Xiao Yuan said.

"Mark, how about it, let's have a game first?" Jessica asked Mark instead.

"I don't play with you, I lose every time." Mark rejected Jessica without hesitation, and said, "Xiao Yuan and I are playing memory battles, winning or losing is secondary, I just want to see if Xiao Yuan can find the loopholes in the system again." ”

"Okay, since you don't want to, I won't force you, Xiao Yuan, you have to come on, don't just enter the innovation lab and let people give you a dismount, although I know that Mark didn't mean that."

"I'll do my best." Xiao Yuan smiled and said.

"Xiao Yuan, Mark's technical characteristics are steady and cautious, and the algorithm is not as sharp as Han Xiaoyu, but it will be very difficult to expel him from the battlefield, but once your program is caught by him, it will be fatally hit, so you have to be careful." Jessica reminded Xiao Yuan again.

"I will pay attention, in fact, it doesn't matter if you win or lose, the key is to experience the fun of learning from each other and find an entry point to improve yourself." Xiao Yuan said.

"You're in a good state of mind, I like it." Jessica affirmed Xiao Yuan's attitude.

"Thank you." Xiao Yuan thanked her.

The innovation lab was quiet, Xiao Yuan looked at the computer in front of him, this computer was left by Robert before leaving, the configuration is very good, compared to the computer in the Smith lab, the system is also FreeBSD, and the conventional software configuration is readily available.

Xiao Yuan spent some time configuring the computer, such as creating his own work account, and configuring the programming environment suitable for himself, and after doing all this, there was still some time, so he began to write a program to play against Mark at night.

Mark is an old man in the innovation laboratory, his technical strength is higher than Han Xiaoyu, Xiao Yuan is not surprised at all, and Mark has a taciturn personality, belonging to the kind of person who can calm down and do research without distractions, this kind of person is often the most terrifying, which can be seen from his ability to successfully become an S-class member of Blackskull without relying on tasks, just by technology, from which Xiao Yuan deduced that if he did not have the advantage of being a reborn, Mark would have no effort at all.

Everyone has to be competitive, especially in the field they are good at, although Xiao Yuan just said that it doesn't matter if he wins or loses, but from the bottom of his heart, he definitely doesn't want to lose, since he doesn't want to lose, then he needs to take it seriously.

Because of the abundance of time, Xiao Yuan did not directly start coding like last time, but took a piece of paper and a pencil from the workbench, and sketched the preliminary structure of the program to be written on the paper.

"Xiao Yuan, good luck." Han Xiaoyu walked over, patted Xiao Yuan on the shoulder, pulled Xiao Yuan back from his state of selflessness, threw him a word and left.

Xiao Yuan put down the pen and paper, looked at the graphics on the paper in front of him, stretched, looked at his watch, and found that it was time to eat, so he put the paper away, said hello to Jessica, and when he was about to say hello to Mark, he raised his head after several calls, and asked a little confusedly, "What did you call me for?" ”

"Uh......" Xiao Yuan scratched his head and said, "It's nothing, you're busy." ”

"Oh." Mark lowered his head again, and stopped moving.

"Mark is the kind of person who is relatively slow to react to things in the outside world except for computers." Jessica explained with a smile on the side.

"Understood, understood." Xiao Yuan said, as he picked up his bag and walked out of the laboratory.

"Xiao Yuan, are you leaving?" He had just walked a few steps when he heard Mark calling out to him from behind.

"What's the matter?" Xiao Yuan stopped, turned his head and asked.

"No, it's just that I'm leaving, and I'm saying hello to you." Mark said, tugging at his glasses.

"Alright then, goodbye, wait for me to come back in the evening, write the program and compete with you." Xiao Yuan laughed and said.

"Goodbye." Mark waved his hand, then lowered his head again, not looking at Xiao Yuan.

Jessica turned her head to look at Xiao Yuan, and found that he was still in a daze, so she couldn't help laughing, and she also stood up, and said, "Mark sometimes slows down by half a beat, you can get used to it in the future, I'll go with you." ”

Xiao Yuan laughed, he always felt that he was a nerd enough in his previous life, and he was slow to respond to human affairs, and now compared to Mark, he is really a small thing.

"The people in the innovation lab are weird, most of them have quirks, you just come in, just get used to it." As she walked out, Jessica said again.

"I have experienced, I think I'm really a normal person in comparison." Xiao Yuan said.

"You also have something that no one else can compare, but you don't know it." Jessica said.

"You mean I have quirks too?" Xiao Yuan asked in surprise.

"Not really, but it's very different from ordinary people." Jessica replied.

"What's the difference?" Xiao Yuan asked curiously, this was the first time he had heard someone want to evaluate him, so he was full of interest.

"I don't know if you have noticed that when you concentrate on something, it is easy to fall into a state of self-forgetfulness, not caring about the people and things around you, and even completely ignoring time?" Jessica asked.

"Sometimes, as long as it's something you like to do, it's normal to forget the time when you're completely immersed in it." Xiao Yuan replied.

"The truth is like this, but how many people can really do this, selflessness is a very terrible realm, and it is also a realm that many people dream of but cannot obtain, and the time it takes you to enter this state is very short, and once you sink in, it is difficult to be disturbed by the outside world, just now I guessed that if Han Xiaoyu just said a word to you and didn't pat you, you probably wouldn't have heard what he said at all, so it can be inferred that this state is a normal state for you, do you say what I said right?" Jessica said again.

"Sort of." Xiao Yuan nodded.

"One more thing, I found out that you might have a cleanliness fetish." Jessica swore endlessly, and said a trait that Xiao Yuan didn't expect.

"Cleanliness?!" Xiao Yuan scratched his head, laughed twice and said, "Are you kidding, if you let Yingying hear this sentence, it is estimated that she will laugh off her big teeth, I am actually a sloppy ghost, if Yingying does not take care of me, it is estimated that the current image will be similar to Einstein." ”

"Albert Einstein?" Jessica listened to Xiao Yuan's analogy, covered her mouth and laughed, reached out and patted Xiao Yuan's shoulder, and then said, "I really didn't expect that you still have the quality of cold humor, are you being modest or boasting?" ”

"Huh." Xiao Yuan smiled and asked, "Where did you see that I have a habit of cleanliness?" ”

"From the time you entered the innovation lab to organize the computer, I noticed a detail, when you were sorting out the computer, almost all the configurations on it were initialized, and the ordinary account that Robert had already created was also deleted by you, and then you created a new account, let me ask you, why did you do this?" Jessica stated some of the facts he had observed, and then asked.

"It's just a habit and I didn't think much about it at the time, is there anything wrong with that?" Xiao Yuan asked rhetorically.

"Then let me ask you, if you don't initialize those configurations, can't you just use them?" Jessica asked.

"Of course you can, but it's uncomfortable to use, how can you describe that feeling?" Xiao Yuan thought for a moment and continued, "It's like wearing socks that others have worn, but haven't washed." ”

"You still say you don't have a cleanliness fetish?" Jessica asked rhetorically.

"So you're talking about this.,I didn't pay attention to it before.,Listening to you say this.,It seems to be true.,But this kind of cleanliness is very personal.,It's not like the cleanliness in reality will have a bad impact on people.,In fact, there's nothing bad about it.。 Xiao Yuan smiled and said, he also remembered some other computer habits, such as not putting any icons on the desktop, the root directory of the hard disk does not allow any non-system files to be stored, regular documents, etc., which are really similar to the cleanliness habit in reality.

"It's not your own personal computer, and it's not good to leave too personal traces of use on it." At this time, they walked out of the laboratory building, and Jessica dropped such a sentence without a head, and then said goodbye to Xiao Yuan and left alone.

Xiao Yuan didn't quite understand why Jessica suddenly said this to himself, standing on the high steps in front of the building, watching Jessica get into the sports car she parked outside the door of the building and leave, before going down the steps and riding a bicycle to find Xia Jiuying.

…………

In the evening, when he returned to the laboratory again, Jessica, Mark and Han Xiaoyu were already in the laboratory in the laboratory, Xiao Yuan sat in front of his camera and said to Mark: "Wait for me for a while." ”

"It doesn't matter, this time our competition is not like the last time you and Han Xiaoyu, there is no time limit, when do you write the program, when will we start." Mark said.

Xiao Yuan didn't speak anymore, turned on the computer, opened his usual vi, and began to write the program, with the program architecture and algorithm implementation ideas that had been conceived in the afternoon, and then the program became confident, just to deal with Mark, who was much more powerful than Han Xiaoyu, Xiao Yuan's program was a lot more complicated, so it took a lot more time, and it took more than three hours to write the program, and the time was more than ten o'clock unconsciously.

"Mark, we can get started, how about winning or losing a game?" Xiao Yuan said.

"Okay, we'll decide to win or lose." Mark readily agreed with Xiao Yuan's words.

It was still the original workstation set as the battlefield, Xiao Yuan and Mark's programs were put in, and when they were about to start, the intercom at the door of the laboratory rang, but it turned out that Xia Jiuying and Lin Ran came to find Xiao Yuan.

So Xiao Yuan first picked up the two from outside the laboratory, came to the battlefield computer again, and said to Jessica, who was in charge of starting the battlefield: "You can start." ”

Jessica looked at Lin Ran, who was standing with Xia Jiuying, and asked, "Is this your sister?" ”

"Hello Sister Jessica, I'm Xiao Yuan's sister Lin Ran, I often hear him mention you, it's good for you to call me Xiao Ran." Lin Ran had already been vaccinated in advance by Xiao Yuan and Xia Jiuying, so after seeing Jessica again, he didn't show much surprise because of her appearance, and when she asked about herself, he introduced himself generously.

"I hope it didn't scare you." Jessica said.

"How can it be, I, Lin Ran, am not so superficial." Lin Ran said.

"Hehe, Xiao Yuan, you have a good sister, I really envy you, if only I could have such a well-behaved sister." Jessica laughed at what Lin Ran said, and turned her head to Xiao Yuan.

Xiao Yuan secretly wiped the cold sweat on his head, and said in his heart: "Well-behaved, that's because you don't understand her, if you understand her, I'm afraid you won't be using the word well-behaved, it's actually more accurate." ”

Lin Ran naturally didn't know Xiao Yuan's mental activities, she came to the computer and asked curiously, "How is my brother going to compete with people?" ”

Jessica was obviously in a good mood at the moment, and patiently explained to Lin Ran while operating, while explaining, Xiao Yuan and Mark's programs were already running, and the originally dark battlefield quickly changed, and the red square representing Xiao Yuan and the blue square representing Mark quickly spread across the entire battlefield area.

"Is this the beginning, brother, how can you win?" Lin Ran asked on the side.

"After all the small blue squares in the battlefield are swallowed by the small red squares, even if I win, but Mark is very powerful, and my chances of winning are not big." Xiao Yuan said.

"I believe my brother, you will win." Lin Ran clenched his fist and waved it in front of Xiao Yuan, and said confidently.

"I believe in you too." Xia Jiuying said with a smile on the side.

"You two are too optimistic, Xiao Yuan's chances of winning are really not big." Han Xiaoyu, who came to watch the battle, said.

"Who are you, and why do you say that?" Lin Ran rolled his eyes and asked aggressively.

"It doesn't matter who I am, the key is the fact of what I said, if you look at the current situation on the battlefield, is it more red squares or more blue squares?" Han Xiaoyu pointed to the ever-changing battlefield, said with a playful smile on his face.

Lin Ran looked at the battlefield, and it was clear at a glance that the battlefield had changed a lot compared to the situation at the beginning, if the area occupied by the blue squares was compared to the night sky, the red squares were like twinkling stars in the night sky, and in terms of absolute numbers, they were already completely at a disadvantage.

"Brother, how can this be?" Lin Ran listened to Jessica and Xiao Yuan's explanation just now, and naturally understood what the situation on the battlefield meant, and he didn't care about arguing with Han Xiaoyu, so he asked a little anxiously.

"It doesn't matter, a spark can start a prairie fire, you should have heard of it, until the last moment, you can't make a conclusion about who loses and who wins." Xiao Yuan said.

"Yes, the last time Xiao Yuan and Han Xiaoyu competed, there were only a few small squares left in the end, and they won in the end." Xia Jiuying remembered the situation of the last game, so she took Lin Ran's hand and comforted.

"Who is Han Xiaoyu?" Lin Ran asked.

"Humph!" Han Xiaoyu snorted coldly on the side.

"Oh, I know, you must be Han Xiaoyu, right, last time you lost to my brother, and your heart is unbalanced, so you come to curse my brother for losing, right?" Lin Ran pointed at Han Xiaoyu and shouted proudly.

"Hmph." Han Xiaoyu snorted again and ignored Lin Ran.

"What are you humming, are you weak?" Lin Ran didn't let go.

"Xiao Ran, be quiet!" Xiao Yuan pulled Lin Ran and stopped her from continuing to make noise.

"Wait until my brother wins, I won't kill you." Lin Ran stared at Han Xiaoyu and muttered, then focused his attention on the battlefield.

At this time, the battlefield has undergone some changes, although the entire battlefield is still dominated by blue, but the red squares seem to be slowly rotating around a certain center, as if there is a certain pattern, forming a specific pattern.

"Xiao Yuan, did you use a parallel algorithm in this program?" Jessica asked suddenly.

"Yes." Xiao Yuan nodded, not denying it, but also not explaining too much.

"What algorithm did you use to organize these parallel threads?" Jessica continued.

"Establish the chaos equation according to the derivation method of the five elements and eight trigrams, treat each thread as a variable in the system, use the master control program to evolve the chaos equation, and the evolution process also borrows some things from the seed evolution program." Xiao Yuan said.

"Have you found the algorithm for the program's decentralized storage?" Jessica finally withdrew her gaze from the battlefield, glanced at Xiao Yuan in surprise, and asked.

"No, I'm using a stupid method." Xiao Yuan said.

"Wow, Taijitu." While Xiao Yuan and Jessica were talking, Xiao Yuan's small red square gradually formed a Taiji diagram during the rotation, which caused Lin Ran to exclaim.

Han Xiaoyu was also very surprised to withdraw his gaze from the battlefield, glanced at Xiao Yuan, and asked, "Why did you think that you made such a thing out, what are you showing off, don't you think it's flashy?" ”

"The pattern is automatically generated by the chaos equation, so I will not deliberately come out with such a thing, this pattern just proves some of my ideas, and also proves that the chaos equation I established in combination with the theory of yin and yang and the five elements is valid." Xiao Yuan said with an indifferent smile.

"Those little squares of yours are almost immovable from Mark's compression, but what's the use of such a pattern?" Han Xiaoyu asked.

"Qualitative change always occurs when the quantity changes to a certain extent, so don't be impatient." Xiao Yuan smiled indifferently and said.

"Qualitative change? Are you thinking about getting root privileges again? Han Xiaoyu asked.

"Wait and see." Xiao Yuan said.

Han Xiaoyu didn't continue to ask, and once again put his attention on the battlefield, watching the slow Taiji Lake gradually shrink, the red squares became denser and denser, and finally turned into a red disk, and he couldn't see the appearance of the Taiji diagram anymore, at this moment, all the squares in this disc flashed rapidly, and this movement quickly attracted everyone's attention.

"Brother, is this about to change qualitatively?" Lin Ran asked a little nervously.

"Yes." Xiao Yuan said.

And just as they were asking and answering, the qualitative change began.
