"What I said is true, I didn't lie to you." Xiao Yuan said seriously.

"I've investigated, you don't have a computer at home, and you don't have Internet access at all, how can you learn those network skills?" Tang Sa retorted.

"You don't understand this, right, my dad's most powerful thing is not software, but hardware, you should know that he always spends a lot of time in that radio repair shop every day, think about it, that radio repair shop really has so many bad appliances for my dad to repair?" Xiao Yuan said again.

"That's right, this thing is really suspicious, so your dad is not repairing electrical appliances most of the time, but surfing the Internet?" Tang Sa was reminded by Xiao Yuan like this, and he also felt that this matter was a little suspicious, so he speculated.

"Correct." Xiao Yuan said.

"But without a computer and no network cable, how can he access the Internet?" Tang Sa asked.

"My dad's methods are not something you can understand." Xiao Yuan pouted and said.

"You should know, tell me about it." Tang Sa asked.

"Your thinking is narrow, do you only have computers, pull the network cable to access the Internet, aren't you also doing wireless networking, in fact, those technologies are all leftovers from my dad a few years ago." Xiao Yuan said again.

"If what you say is true, your dad is amazing, but I don't believe it." Tang Sa blinked and said.

"To believe or not to believe, there must be a reason, what is the reason for your disbelief?" Xiao Yuan asked.

"You think I'm a child, whatever you say I believe, not to mention that wireless networks are still in the research stage in the world, although there are some results, but they are not too mature, the domestic civil network, there is no wireless access protocol at all, it is difficult for a clever woman to cook without rice, your father's ability is high, there is no infrastructure conditions, how can he be on the Internet, this is just a doubt, another doubt, your father's experience I have also investigated, ordinary workers from a family, go to college, graduate, worked in the Nanzhou Radio Factory for many years, and then went home and opened a radio repair shop, which pulled you up, and his experience did not have the conditions to become a super hacker at all. Tang Sa said.

"I just said, what you see is just a superficial phenomenon, forget it, I won't explain it to you, believe it or not." Xiao Yuan waved his hand and said.

"But your father suddenly sent you to Jiangzhou, and suddenly disappeared, but it is a little suspicious, I have to find someone to investigate, and I will talk about it when the investigation is clear." Tang Sa said again.

"Sister Sa, what department of the country are you working for, and you seem to be very powerful?" Xiao Yuan couldn't help but ask, although he knew that Tang Sa would not answer his question, but he still wanted to ask, because Tang Sa knew his situation well, but he didn't know anything about Tang Sa, this kind of information asymmetry made him feel very unhappy.

"Brother, my sister doesn't tell you, she's protecting you, sometimes, I know more, it's better to know less, hurry up and pack up your things, my sister will take you home." Tang Sa really didn't answer Xiao Yuan's question, but wanted to leave with him.

"Okay, it's late today, let's move on tomorrow." Xiao Yuan looked at a watch hanging on the wall of the office, the time was already eleven o'clock, although he rarely slept at this time, but it was rare that he did not go home at this time, so he readily agreed.

…………

"Sister, my family should take that road, how do you take this road?" On the way, Xiao Yuan found that the road Tang Sa was driving was not the way to his house, so he asked.

"Going home is for you to go back to your sister's house." Tang Sa said.

"Sister, it's still not good, lonely men and widows, I'm afraid it will not affect you if you are in the same room." Xiao Yuan hurriedly said.

"What's the impact is not good, my sister is not afraid of being a girl, what are you afraid of as a boy, besides, my sister took you home, and she didn't let you go home to rest, she asked you to go home and continue to work and help my sister solve problems." Tang Sa said.

"With you using people like this, you don't let people sleep in the middle of the night, and you still let people work, no, I protest." When Xiao Yuan heard this, he protested with some tears and laughter.

"Protests are ineffective." Tang Sa directly rejected Xiao Yuan's protest, and then changed to a pleading tone, and said, "Brother, you can help my sister, if it weren't for the urging from above, I would be reluctant to let you rush to work overnight, and when I went to look for you, I had already told Teacher Yang that if you don't go home today, they may have slept at this time, and you won't be able to enter the door when you go back." ”

"Okay, okay, it's hard to have a sister like you." Xiao Yuan heard that Tang Sa had already given him a salary from the bottom of the kettle, and said helplessly.

"Hee-hee, this is my good brother." Tang Sa saw that Xiao Yuan had yielded, so he smiled, stepped on the accelerator under his feet, and the sports car sped up and drove forward, and soon arrived at the apartment where she lived.

This apartment is Xiao Yuan's first time since last year's National Day, although it has been a few months, but the layout inside is still so familiar, when he walked in, the things that happened in this apartment a few months ago were as if they happened yesterday, vividly.

Tang Sa's face was a little red, and he seemed to remember what happened last time, and the two of them stopped talking for a while, and the atmosphere was a little strange.

"Brother, you go to another room." There was silence for about ten seconds before Tang Sa spoke.

Xiao Yuan didn't speak, he went directly to another room, and when he went in, he saw that there was a computer and a desk inside, and there was a large bookcase inside, and there were a lot of books in the bookcase, just like a study, so he walked behind the desk and sat down, and continued his work.

Tang Sa walked in with a cup of steaming coffee after about ten minutes, and put it on the table in front of Xiao Yuan, but he didn't bother Xiao Yuan, but stood behind him and watched.

"Sister, you better go out, it's uncomfortable to stand beside me like this and stare at it." Xiao Yuan felt that someone was staring at him, and he felt a little weird, so he said.

"Red sleeves and incense can't be envied by many people, you actually drove my sister away, you really don't understand the taste?" Tang Sa saw Xiao Yuan driving her out, and he gave him a somewhat unhappy glance and said.

"I can't afford to add fragrance to the red sleeves, you stare at it like this, it can only make me unable to concentrate on thinking, and it's not bad for me to delay time." Xiao Yuan said with a smile.

"Okay, okay, my sister is out." When Tang Sa heard Xiao Yuan say this, he was probably really worried that the progress would be delayed because of her influence, so he immediately relented, turned around and went out of the room, and quietly helped Xiao Yuan close the door before leaving.

Xiao Yuan continued to write and draw on paper, at this moment, he imagined an extreme situation, substituting himself into a special operations team composed of several people, performing tasks in a very complex terrain environment, all these special combat team members carried wireless terminals temporarily formed a centerless adaptive wireless network, but because of the complex terrain and arduous tasks, some team members may break away from this network at any time, and then may join it at any time, regardless of whether the team members join or leave, It is necessary to ensure the stability and normality of the wireless network, that is, the wireless network should have the characteristics of adapting to the rapid addition and deletion of nodes, which is the specific meaning of high adaptability.

In view of this characteristic, the ring logic lock must also have this characteristic, when a special combat member (abstracted into a node) leaves, a node of the ring logic lock is deleted, and other nodes that are still in the network should be able to quickly form a new ring logic lock and work normally, that is, the ring logic lock must also have a very strong adaptability.

In response to these characteristics, Xiao Yuan constantly adjusted the structure of the algorithm, and his brain completely sank into it, entering a state of self-forgetfulness, during which Tang Sa quietly came in a few times, and even replaced his cooled coffee with hot ones, he was completely unaware of it.
