Yang Yan's reaction had the vigilance and precaution of normal people, and there were also flaws left behind by pretending to be calm when inviting them into the house, Dong Yue saw it very clearly, but what made him feel very strange was that when he reported himself to his home and said that he was a national security department, Yang Yan's surprised reaction lacked the confusion that should have appeared!

Why the national security services?

Why did the national security services approach me?

Shouldn't normal ordinary residents have a few question marks popping up in their minds when they are faced with an investigation by officials from the state security department?

Yang Yan didn't want to hide it, but now that the other party has come to the door, he said very calmly: "Because you tried to crack the software I left in the server of the Guangdong Provincial Public Security Department last Friday night, I know it!"

Listening to Yang Yan point out the time point last Friday, Dong Yue and Yuan Xian both looked at each other awkwardly, Dong Yue's eyes widened, and he glanced at Yuan Xian with a little hatred.

You guy, you can't do anything, and you left your tail for people to discover!

"If I'm not mistaken, that hacker that day should be you, right? Yang Yan pointed at Yuan Xian, smiled faintly, and said.

This is really murderous, Yuan Xian was so embarrassed that he wanted to find a crack in the ground and get in, he sat on the side, covered his face, and didn't know how to answer.

Fortunately, Dong Yue relieved him: "Yang Yan, I apologize to you first about this matter." ”

Dong Yue didn't just talk, he also stood up and wanted to sincerely apologize to Yang Yan.

Yang Yan couldn't stand the fact that someone older than him bowed to him, he hurriedly stood up from Luoluo's side, supported his hands out of thin air, and said, "Director Dong, it's okay, I don't care about this matter very much, because after all, you haven't broken through my firewall yet!"

Although it was just a casual sentence, Yuan Xian covered his chest and looked like he couldn't cry or laugh - this is really murderous.

Of course, Yuan Xian also had to be convinced, because at the technical level, Yang Yan was indeed stronger than him, and he was indeed ...... Failed to break through the firewall program written by others.

Ignoring Yuanxian for the time being, Luoluo sat beside her father obediently, she couldn't understand the complicated conversation between her father and the other party, and she couldn't understand the complicated relationship.

But when I saw these two uncles and uncles who came to visit, I seemed to be a little overwhelmed by what my father said! The little girl's cute big eyes reflected her father's big ass blocked in front of her, and on the other hand, she faintly revealed a hint of adoration for her father!

Daddy is so amazing!

Yang Yan is still saying: "However, to be honest, although I made this system in the hope that it can help those who are eager to find their relatives, and I want to provide it to the public security department for free in the future, but, no matter what, I have intellectual property rights for the code of this system." ”

Yang Yan wants to do good deeds, but he is not a fool, not a big fool who likes to give in vain!

He knew that the purpose of the two people from the national security department who came to visit him must be inseparable from his own system. But he didn't want to be asked for nothing to take away the results of his hard work, so he put some words in front first.

Dong Yue sat back, he didn't get confused because of Yang Yan's words, the expression on his face returned to calm, under the thick eyebrows, those eyes looked at Yang Yan's eyes keenly, and said with a calm smile: "Yang Yan, what you said is right! The reason is that we have seen an application report from the Ministry of Public Security, which is about using your system to improve the effectiveness of our existing Tianyan system......"

This report was written by Mr. Dai Guoxun himself and then submitted. Yang Yan also knew that Mr. Dai had told him that his system needed to reflect its value beyond the fight against abduction in order to successfully pass the approval.

However, despite Mr. Dai's tireless efforts to travel to the capital for more than a month, the report was still stuck.

"It's us who hold this report!" Dong Yue answered Yang Yan's doubts, "Yang Yan, your system is very powerful, not only to recognize faces, but also to recognize the appearance that has changed due to the changes of time, and even to recognize the faces of different hairstyles and simple makeup......"

It is precisely because it is so powerful that the national security department has taken it seriously.

"If this system is used in our customs monitoring network, it is used in various airports, high-speed rail stations, ports, ......" This time Yuan Xian added that although he did not crack the firewall of Yang Yan's system, he still used this system to conduct face recognition tests (Yang Yan did not set permissions in use).

"In that way, if there is a criminal we are wanted to escape from abroad, Yang Yan, this system of yours can immediately find him out, and we can catch him before he escapes!" Yuan Xian clenched his fists and said in an affirmative tone.

"It's like Yang Yan, the medical fraud case you reported before, the He Jiawei who escaped, and now the province is applying for him to be included in the ranks of red notices, but no matter what, if we have this system, he can't escape, and he will be arrested directly at the airport!" Dong Yue said with a smile to Yang Yan.

They also know He Jiawei? Yang Yan suddenly felt that now he seemed to be exposed to the spotlight of others!

This feeling...... It's really unhappy, but Yang Yan is helpless, in front of this level of state machinery, he can only choose to be silent.

However, even if he tolerated it, Dong Yue, who knew how to observe words and feelings, still saw Yang Yan's mood swings, so he took the initiative to say: "I'm sorry, due to the special nature of our work, some things can't be said in the open, so there is a matter of Yuan Xian wanting to see your system code before, as well as our investigation of you, but don't worry, we have no malicious intentions." ”

Yang Yan nodded with a wry smile.

What else could he do without nodding?

"Yang Yan, we really need your system, with this system, many criminals who are trying to flee in China have nowhere to hide! The security of the country needs your system!" Dong Yue said to Yang Yan sincerely.

Dong Yue didn't tell Yang Yan completely, their national security department needs Yang Yan's system, and it is not only the Chinese who are monitored, but the foreigners who enter and leave the country!

When it comes to these national security issues, it is very complicated, and Dong Yue thinks that Yang Yan does not need to know so much.

Yang Yan frowned slightly, it's not that he doesn't understand the national righteousness, but he doesn't like others to use the national righteousness to force him to hand over his intellectual property rights.

Dong Yue saw Yang Yan's unhappiness, he pressed his two hands, and said with a smile: "Yang Yan, don't get me wrong, we don't want you to pay for nothing, in fact, we want to make an exchange with you that can be said to be of equal value!"
