Live Shura field

Li Lu and Yu Qiu were overwhelmed by this question, staring at Nan Junliang speechlessly.

Nan Junliang paused, and said: "I'm not saying that your boyfriend is dead, I'm just talking about this concept. This is a relatively classic plot in novels and movies, that is, when a person dies, in order to leave a memory for his lover I want to, so I will write many letters in advance and send them to the other party regularly."

"Not only lovers, but also settings like parents and children."

Yu Qiu said: "So these text messages...are similar to the love letters of the deceased!?"

Nan Junliang said: "To be precise... this is a kind of chat robot created for you personally, Sister Li. This robot uses your boyfriend's tone and personality settings, and then based on what it knows about you, it presets Various possibilities, and prepared corresponding responses. Your boyfriend's computer skills...should be pretty good, right?"

Yu Qiu said: "Three months ago, he went to the head office for training because he was promoted to the director of the technical department of the branch."

This truth is actually far more cruel than what Li Lu expected.

On the eve of promotion, he left suddenly.Sudden derailment, broke up with the girlfriend who was deeply in love, and then never answered any calls, but kept replying to text messages diligently, trying to comfort her.

All of this points to a very bad possibility.

Li Lu said: "How is it possible!? He is in good health, much better than me! Although the work is tiring, he has been exercising and rarely gets sick!"

Nan Junliang said: "Don't worry! Don't... rush to make the worst judgment. In fact, even if it is a love letter from the deceased, we can at least be sure that the person involved must still be alive when writing the love letter."

With tears streaming down her face, Li Lu said, "But if that's the case, why didn't he tell me? Why did he act out such an infuriating scene?"

Nan Junliang was silent for a while, and then said: "Because you two are too much."

Li Lu was taken aback.

Nan Junliang said: "I'll just say it straight. I don't know what a childhood sweetheart is, but I think you and your boyfriend, Sister Li, are going too far. From what you say, both of your parents are still alive. But you seem to only care about each other, and you only consider each other when you make decisions. For example, you said before that you had an agreement to live and die together, and you said that if you were abandoned, you wanted to commit suicide?"

"If he really died, would you die with him?"

Li Lu was silent for a long time, unable to answer this question.

It seems that no matter how you answer it, it will not be the correct answer.

Nan Junliang said: "When you wrote your suicide note, you felt that if you were really going to die, what would you worry about the most?"

...what to do with the living parents.Feeling ashamed, feeling sorry for them, and feeling... unable to face the sadness and despair they might have.

Nan Junliang said: "I think when people know that they are going to die, in addition to being afraid of death, they may be the ones who are worried about being left behind. The better the relationship, the more worried they should be. But even so, you obviously I don't have the energy to think about these issues anymore, or I feel that these things... are not as important as your feelings."

Nan Junliang actually didn't want to blame the other party for this problem, but he had to do so.

He said: "It's probably the same for your boyfriend. But maybe because he didn't want to commit suicide, he felt less guilty about his parents, but only cared about your feelings. Although I'm not sure, but he probably I feel that doing this will reduce the harm this matter will do to you.”

"It's too much, you know? Both of you have done too much, especially cruel to the elders. Your parents and his parents will be very hurt. It is cruel for a white-haired person to send a black-haired person. Disparaging comments are also cruel. So, I say you are too much."

Li Lu didn't speak for a long time, and finally said after a while: "I know...I understand. I won't commit suicide! I won't...let him be scolded."

"You promise?" Nan Junliang was aggressive, "Even if something happened to him?"

Li Lu said: "I promise." She said, "I admit that I am very shocked, I feel very hopeless just imagining this incident. But no matter what, maybe I did have the urge to commit suicide before, but then It was just a spur of the moment."

"I still have mom and dad, and he also has mom and dad. If... if there is an eventuality, I can't just do nothing and just go with him. Although death is easy, it's too irresponsible gone."

Nan Junliang said: "Okay, that's all. Sister Li, if you have this awareness, I will try my best to help you find him."

When he said that, Li Lu immediately became nervous again, and asked, "How are you going to find it?"

Nan Junliang said: "Do you know... the signal can be located?"

His thinking is very clear: "The chatbot made by your boyfriend should be tailored according to your personality. That is to say, it will use your knowledge level, professional ability, and behavior patterns as a reference to make a Respond accordingly."

"This shows that it has quite limited means of coping with other people whose behavior patterns are very different from yours, and it also lacks defense capabilities. Of course, since your boyfriend has strong computer skills, I guess there should still be basic defense capabilities. I If you are a rookie at the level of hacking, you will not try the difficult work of hacking."

"Let's use the dumbest method. Let's start by preparing the tools we need."

This kind of positioning requires tools. Unfortunately, Nan Junliang can't afford the really useful equipment.As a social person, Li Lu may be able to buy a cheaper one, but it is estimated to cost several thousand, because such a thing is unnecessary after all.

Nan Junliang's hands-on ability is actually very strong.His parents are both top scientists in the country, and they are the real kind of people who will add the word "family" after them.He himself is considered a not-so-technical nerd, the kind who knows a little about many things, but doesn't go deep into any of them.

But speaking of it, being born in this kind of family, the learning conditions must be much better than the average person's, and he can be called a genius if he is exposed to it, not to mention that Nan Junliang's mind is already quite easy to use.

For example, although he has never done this signal capture, he has a general understanding of the principle and which machines have similar functional components.After inquiring about Li Lu, he found an electronic equipment repair shop nearby, and after negotiating with the other party repeatedly, he got the other party to agree that he could pick up some discarded parts at a low price.

He combined these parts into a messy instrument, and then a group of people spent several hours capturing, calculating and analyzing the information signals Li Lu sent and received from her boyfriend's mobile phone, adjusting the position and calculating all the way, almost The entire main area of ​​Yushan swayed around, and finally calculated the real location of the mobile phone based on the geometry of the signal propagation speed of the map drawn by Nan Junliang.

During this process, Nan Junliang started a live broadcast by the way.The audience seems to be very interested in this signal search method with the characteristics of the times, and they are quite moved by the wisdom of the "ancient people".There are too many flaws in this, and as an "ancient man", Nan Junliang basically can't understand their fuss at all.

In the final analysis, this is like marveling at the fact that ancient monkeys can walk upright, which itself carries a little arrogance, a sense of arrogance as a citizen in an era of advanced technology.

They haven't used such a crude instrument for many years. For the future audience, its function is a bit too simple and crude, and its usage is a bit too complicated in comparison.

This is also a characteristic of the development of science and technology-the more technology develops, the more complex the way it works, and the simpler the way it is used.There will be an insurmountable gap in the understanding of technology between professionals and ordinary people.

The area Nan Junliang circled at the end made Li Lu fall into deep thought.

Then at this time, Nan Junliang suddenly asked: "Sister Li, you and your boyfriend are childhood sweetheart neighbors, right?"

Li Lu froze for a moment, then hummed.

"Do you have a good relationship with your parents-in-law?"

Li Lu said: "Very good. My aunt and uncle are like another pair of my parents. When he first said that he would break up with me, they were very angry and said that they would not accept such a thing anyway, but then... ..."

She didn't finish what happened afterwards, but it must have been a change of attitude.Li Lu herself seemed to be aware of the strangeness, and asked with some uncertainty: "...they...do they also know?"

Nan Junliang spread his hands: "If you ask me about this kind of thing, I can't know it. After all, I don't know them. But if there is a sudden change in attitude, there must be a reason for it?"

"But, I didn't say... If this is true, then your boyfriend really loves you very much... It's too much."

Li Lu said: "No! I'm too fragile, that's why he worried."

Nan Junliang sighed and said, "It's probably within this range. Can you roughly guess where he put the receiver?"

Li Lu looked around and said, "If it's around here... I remember that he has a good friend who rents in this community. He is his colleague and roommate from college."

Nan Junliang said, "Let's go find him."

Li Lu didn't know what to say, and said, "So he knows too. No wonder..."

Nan Junliang: "?"

Li Lu said: "We had a quarrel before, and he was the one who said that I was a stalker..."

After hearing this, Nan Junliang said, "No matter what, we should know the truth soon."

Yan Ximin seldom expressed his opinion when talking about serious matters because he was not clear about the situation. At this time, he couldn't help but said: "It's really complicated. You guys are making simple things too complicated, right?"

Li Lu hesitated for a while, but still did not explain.

Yan Ximin and Nan Junliang are still too young, and they have no scruples.People's feelings are naturally complicated, so complicated that sometimes they can't understand it, so how can it be simple?

Li Lu took them to the door of the target apartment.They knocked on the door but there was no response and no one seemed to be home.However, Nan Junliang captured and measured the signal again, and basically confirmed that he did not find the wrong party.

They tried to look into the house from the window, and finally found some clues.Although there is no one in the room, it seems that there is a computer running, and there seems to be a mobile phone connected to the computer in front of it.Nan Junliang asked, "Is that your boyfriend's cell phone?"

Li Lu tried to distinguish for a while, and replied: "...I can't see clearly. But it seems to be the same model..."

While sneaking around, a roar came from behind: "Who are you!? What do you want to do!?"
