Liu Chen glanced at the time, it was eight o’clock, and his sister was still waiting for him to go back at home.

There is Song Jia watching over there in the virtual city, and there is not much problem, that is, on the side of the interrogation room, the person who reported the case is obviously in trouble.

Cheng Fang and the senior of the old criminal police were interrogated in the interrogation room, and the guy’s mouth was quite hard.

I have always said that I reported the case well, but I was actually treated as a suspect, full of anger, and the performance was in place.

Liu Chen who watched it was sleepy, and it was no good to know that he didn’t say anything.

After the interrogation, Cheng Fang walked out dejected, slightly tired.

In order to investigate the mysterious man’s case these days, it is very busy.

Finally, I have a clue, and I dare not relax for a moment, and it is best to chase after it.

“Senior sister, let’s ask tomorrow, let’s dry him for a while before talking, and think clearly about yourself!”

Liu Chen looked at him like that, even if there was anything, it was difficult to pry open his mouth now.

“Well, let you guess right, this guy does have a problem, Xiaochen, you go back first, isn’t someone still waiting for you?”

Anyway, I can’t ask anything, Cheng Fang also plans to go back and continue to ask tomorrow.

“Okay, Senior Sister, I’ll go first.”

There are indeed people waiting for him, and the big sister estimates that she has already made dumplings, so she waits for someone to go back.

On the side of the virtual city, let Song Jia stare at it, and after the defense is installed, the tracking software will be implanted later, and it is urgent.

Drove Cullinan back to Rongjiayuan, and as soon as he arrived at home, he saw a message from the group.

Su Yanxi shared the dumplings made to the group and posted them to the circle of friends.

The accompanying text is: hand-packed, I hope Mr. will like to eat (shy)

The love show is good, President Su personally made dumplings for her husband to eat, it is estimated that it is another big news in the company.

Someone immediately liked it below, undoubtedly Wang Meili, and praised, the daughter-in-law is really powerful.

The corner of Liu Chen’s mouth twitched, mom, you’d better not go into the kitchen, I’m really afraid.

The stew soup is not good to stew, let alone make dumplings, I am really afraid that she will be poisoned.

“Sister, I’m back.”

“Come back, then I’ll put the dumplings down the pot and cook, you’ll be later!”

Su Yanxi stretched out his head and glanced at the door, quickly took the dumplings to the kitchen, and boiled the water first.

Liu Chen first went to the bathroom to take a bath, did not take a bath for a day and night, and went to see the corpse, and his body was smelly.

He rinsed a few times, changed into pajamas, blew his hair half-dry, and then walked to the kitchen.

The beauty is wearing an apron and holding her hair, and she is busy in the kitchen.

Reach out and cover her slender waist from behind, and put her head on her sister’s shoulder.

Gently sucked the fragrance on her body, the smell on the girl’s house was indeed good.

“It looks delicious.” Liu Chen looked at the dumplings in the pot, and the wrapped 043 looked.

“That’s a must, your senior sister said that it was delicious, and it could not be deceived.”

Su Yanxi was a little proud, and she was also looking forward to what Liu Chen’s evaluation of her was.

It’s not that I’m afraid of not eating enough, the dumplings were boiled in a pot, steamed in a pot, and mixed with a sauce.

After a while, they all served on the table, and Su Yanxi sat on the opposite side, looking at him with gentle eyes.

Such a sometimes gentle, sometimes domineering, sometimes royal sister’s daughter-in-law, in fact, is not bad.

Gao Leng left it to others, tenderness to him, they loved everything and were afraid of something.

“Taste it!”

“I’m going to eat what my sister feeds.” Liu Chen supported his chin with both hands, waiting to feed like a child.

Su Yanxi smiled and rolled his charming eyes, and the smelly brother knew to take advantage.

Picked up the chopsticks, clamped a steamed dumpling, dipped a little sauce, and fed it with his hand.

“How’s it going, is it delicious?”

“Well, that’s not bad.” Delicious nodded, quite like a little daughter-in-law.

It was affirmatively recognized, and the big sister was also happy, and she was feeding Liu Chen the whole time.

A bowl of boiled, a basket of steamed, all eaten clean, a little stretched.

After packing up the dishes and chopsticks, it’s not too early, and tomorrow I have to go to the bureau to get busy.

Just lying on the bed, Liu Chen was still thinking about what kind of relationship the police caller had with the deceased.

In other words, what kind of relationship he will have with the mysterious man, the bureau can only lock him up for a while.

If there is no evidence, he will let the person go tomorrow, it depends on whether he can figure it out.

Su Yanxi came out of the bathroom, the line pajamas could not be covered, her figure was too perfect.

“Lie down.” The position was warm, Liu Chen changed the position and let her lie down, and now it seems that her complexion has improved a lot.

“Why are you still frowning?” The jade hand touched his forehead and gently smoothed it: “Is the case in the bureau tricky?”

She also heard things like the body found, she was afraid that she was not afraid, but she also knew that things were very troublesome, and they were all involved in murder.

“Well, the virus that the mysterious man said has not yet appeared, but it does not mean that there will be none.”

“I’m developing a virtual city, and if there is a virus invasion that he said, it will be led into the virtual city, and I can lock the target and track the location.”

Liu Chen held the beauty in one hand, and with the other hand, he lifted his big sister’s jade hand, kissed it and then held it tightly.

“I believe in your strength, will solve these things, and will also find out the mysterious person.”

“Why are you so sure?”

“A woman’s sixth sense has always been accurate, anyway, you will.”

Su Yanxi arched at Liu Chen, okay, my sister believes in him so much, it seems that I have to work hard.

“Go to sleep!”

He raised his hand to turn off the light, but the person in his arms was not honest, put his hand into his clothes, and touched his chest muscles.

“My wife is not very obedient, and she is not afraid of me…”

“Don’t be afraid, don’t you dare, you won’t, don’t say anything about what you want to do.”

Oh, isn’t it because his aunt came, he couldn’t move, so he frantically prodded him.

“Okay, this time I admit defeat, not next time.”

“Uh-huh!”

Su Yanxi didn’t deny it, so let’s talk about it later, it’s still early.

Early in the morning, Liu Chen got up, the person in his arms was still sleeping soundly, he washed up and made breakfast.

Dropped a kiss, packed up his things, and went to the bureau, time was urgent, and it was urgent.

“Song Jia.”

“Here you are, take a look, the defense system is already good, while attacking the other party, it can protect itself, it has been tested.”

“Hard work, leave the rest to me.” Liu Chen patted him on the shoulder, staying up for two days and nights, he was going to become a national treasure.

Song Jia is also not polite, pack up his things and go home to catch up on sleep, and the later procedure is handed over to Liu Chen, he doesn’t have to worry about anything.

The defense system is fine, the next step is to install the tracking system, and the last one is no problem, and it can be put into the Internet.

They are all busy in the back, typing the code intently while checking the installation.

Press the confirmation button, the virtual city is finished, and he immediately puts it into the major websites.

As long as there is a virus invasion, it can be sensed at the first time, and it can block and lock the target.

It depends on when the mysterious man throws himself into the net, the Internet police are always ready and will go all out to assist Liu Chen.

“What about Cheng Fang?”

Jiang Qi walked in, still holding a report in her hand, which was the result of her all-night testing.

“Forensic doctor Jiang, my senior sister was called away by the Zhao Bureau, is the identity of the deceased confirmed?”

“Yes, you kid is smart, according to the comparison results of DNA and fingerprints, it has been confirmed.” (Read violent novels, just go to Feilu Fiction Network!) )

“Can you let me see it?”

Although Liu Chen is not a member of the police station, he has something to do with this case and is also one of the people in charge.

“No.” Jiang Qi handed it over without thinking, she was a little curious about the young man in front of her.

The folder opens with information about the deceased, as well as photos.

“This face, are you sure it’s right, he seems to be very similar to the police officer brought back yesterday.”

“Is it? I didn’t pay attention, you say that, it seems to be quite similar. ”

Jiang Qi didn’t even notice this, and he had been testing the results yesterday, just wanting to quickly confirm his identity.

I didn’t notice that the deceased and the police did look similar, and now it seems that they are indeed related.

Name: Tang Ming, age 36, height: 168, ancestral home: from Yangshu County, Wangcheng City…

What is the name of yesterday’s policeman, oh yes, it’s called Tang Qiang.

In that case, they are brothers, and they didn’t admit it yesterday night, saying that they were the dead people found by fishing.

It seems that it is not so simple, there is a cat in it, and it is not small, he must know who the mysterious man is.

“Xiaochen, Doctor Jiang.” Cheng Fang came back, his face was not very good.

“Senior sister, what did Zhao Bureau say to you?”

“It’s nothing more than asking me to solve the case as soon as possible, if Tang Qiang is not a suspect, we should release him in an hour.”

Cheng Fang was a little annoyed, the man’s mouth was too hard, soft and hard to eat, (beea) did not dare to say anything.

“Tang Qiang is the brother of the deceased Tang Ming, the report is out, senior sister, you can continue the interrogation.”

Liu Chen handed over the test report, which was enough to keep Tang Qiang.

The deceased was his own brother, and he could pretend to know nothing.

After seeing the report, Cheng Fang was first surprised, then angry.

“Look if I don’t pry his mouth open!”

The group came to the interrogation room again, and Tang Qiang was brought up, still looking careless.

Liu Chen put on headphones and watched his every move and micro-expression through the glass.

In the police academy, there is a lot to learn, and observing people’s micro-expressions is one of them.

Cheng Fang put the test report in front of Tang Qiang, but he didn’t have any expression, what did it mean?

“Know, it’s not a stranger, Tang Qiang, this person is your brother, he died, aren’t you sad?”

“He deserved it, and he didn’t listen to me to end up like this.”

Tang Qiang spoke lightly, and he couldn’t see any sad expression on his face.

Liu Chen frowned, is this guy so indifferent to his own brother?

Or, is he hiding something? There would be no wave for Tang Ming’s death.

So why did you call the police again yesterday? He also lied that he found it while fishing.

Something is wrong, something is really wrong, Tang Ming and the mysterious man are superiors and subordinates, so what about him? You can’t get rid of it.

“How did you find Tang Ming’s body, it won’t really be a coincidence, fishing found it, right?”

Cheng Fang saw that there was hope and continued to ask, who knew that this guy lowered his head again and said nothing.

What kind of operation, ask a word and do not answer, what is the matter of twisting and pinching like a mother?

“Answer, Tang Qiang, you need to know that you are now listed as a suspect, if you want to go out, please cooperate.”

People’s patience is limited, yesterday asked for so long without saying, today it is hard to say, and the result is two sentences.

People are going crazy, and Cheng Fang almost went up to punch him, more than the girls.

The threat is useless, he still doesn’t speak, doesn’t speak, hum, quite personality, right?

“Senior sister, how about I try it?”

Liu Chen shouted into the headset, he can not only draw big cakes, but also brainwash… Bah, that’s called social engineering.

Maybe it can be used to make Tang Qiang willingly say the whole of the matter.

Cheng Fang was stunned, it stands to reason that Liu Chen cannot come in for interrogation, and he does not have this qualification.

After exchanging glances with the old criminal policeman, he decided to suspend the interrogation first and went to the next room.

“Xiaochen, you want to interrogate him?” Cheng Fang asked again, afraid that he had misheard.

“Yes, you can try, maybe I can set his words, I will brainwash… No, it’s social engineering. ”

“Maybe you can try, but he really wants to say it.”

Liu Chen smiled cheekily, social engineering, or social worker for short, is an art of deception.

It is also an indispensable part of cybersecurity, people who do not understand social workers, think that social workers are scams, and only those who understand social workers understand how scary it really is.

Social engineering is a means of harming such as deception and harm through psychological traps such as psychological weakness, instinctive reactions, curiosity, trust, greed and so on of the victim.

The initial manifestation is to attack the weakest link in the information security chain with human factors.

An attack method that invades the computer system of a deceived.

Later, after extending to the real society, social workers usually used conversations to extract users’ secrets in order to collect information and infiltrate victims.

Social workers can do a lot of things, hackers understand this discipline, as long as they use it well, it is the right time.

If it is used to do bad things, it is a criminal means, right or wrong, just in a thought.

Liu Chen can use this to weaken Tang Qiang’s defensive psychology and then make a routine.

This is closely related to psychology, although it is generally accepted that sociology is the study of human social relations.

Psychology is the study of the psychological state of individuals, but sociology is actually the study of the interaction between society and people, or between the collective and the individual.

Cheng Fang actually agrees with this, Liu Chen’s social engineering is no worse than psychology.

After exchanging glances with the old criminal police, she went to ask Zhao Yunshan, which is also a special case.

If Liu Chen returned to the police force, he would not have to bother so much, but it is a pity that he is just an outsider now.

Although they are one of the people responsible for the case, it is their job to interrogate this matter.

In the end, Zhao Yunshan agreed, making an exception for Liu Chen to inquire, and also wanted to see how the strength of this kid was.

“Click!”

The door of the interrogation room opened again, Liu Chen walked in with a smile, and Tang Qiang was also vigilant.

“Why, the previous interrogation can’t come out, change you hairy boy to interrogate me?”

“Hmph! Your public security bureau is only capable of this, and if you want to set me up, there is no door. ”

“Let you interrogate me, do you think too highly of you or too much of me?”

Tang Qiang crackled a lot, his face was hideous, his eyes were angry, and from time to time he laughed at the bureau.

But Liu Chen just didn’t say a word, just looked at him with a smile.

“Are you a fool? Just know laugh? Or do you want to use this to insult me? Tell you, I won’t say anything. ”

Liu Chen was really a little creepy, I don’t know why, obviously in front of him is a hairy boy.

But the moment his eyes met, he couldn’t help but shiver.

I am actually afraid of a little furry child, I almost want to die of laughter, but I don’t know, this is also a tactic in social workers.

From the moment Liu Chen opened the door, social engineering began, and Tang Qiang was undoubtedly taken with the rhythm.

“I think, your own brother was killed, you are not sad, it should be that he did not listen to you and became a disobedient child, so he was angry, right?”

Seeing that he said so much, Liu Chen also unfolded his words, breaking his heart with one word.

When I was a child, I felt that I was the eldest brother, and my younger brother should listen to him, but suddenly one day my younger brother was disobedient, and my instinctive reaction was to be angry and angry!

But more sadness, from under his eyes at the moment, what was captured was disappointment, his disappointment in Tang Ming.
