"The mobile phone is an anonymous mobile phone, and the base station that sends the signal is nearby. The special thing is that a total of three base stations were found."
"Ah? What does this mean?"
"The call time was only 1 minute and 35 seconds, but three base stations were found. The average radius covered by a base station is about two kilometers, and the speed is 80 kilometers per hour, which is exactly the average traveling speed of the subway."
Hao Weida seemed to suddenly understand something.
"That's right, the subway. The only one that can travel through complex urban areas at that speed at this time is the subway."
"Subway, anonymous cars, anonymous mobile phones, changing voices, confusing locations...he is obviously an expert in this field."
"How long will it take for the voice to recover?" Yuan Chen asked again.
"It may take a long time. Judging from the way the voice changes, it should be an old model made in China. But the older the model, the more troublesome it will be to analyze it digitally."
"It seems that this guy is not using products that can be easily found, but old antiques."
............
Baiyan District Digital City.
After getting out of the taxi, Hao Weida scratched his head, looked around, and walked down an alley.
However, after turning out, all I saw along the way were shops that had closed down long ago and were in a state of dilapidation.
"Oh, I haven't been here for ten years, everything has changed. Where have these people been? Have they gone to hell, or have they changed their profession? Really!"
While walking, a person suddenly jumped out from behind.
"Brother, big brother, big brother..." He patted Hao Weida.
"What are you looking for, Viagra? Cialis? I have all the ones that are good for replenishing the kidneys and strengthening virility." He licked his lips with an evil smile on his face.
Hao Weida didn't even bother to look back, and kept walking forward on his own.
"I'm pretty strong even without patching up, it's just that I have no place to use it." There was a trace of sadness in his tone.
But the man showed no intention of backing down.
"Ah, big brother, big brother, as soon as I see your face, I can tell that you are full of energy. Nothing else is interesting, like peeping cameras and eavesdropping devices."
Hao Weida stopped and looked at him with amusement.
"I said, how long have you been working here?"
When the man saw that he was finally willing to talk to him, he was so happy that he showed a row of white teeth.
"What, are you looking down on me? Brother, in fact, I just look young. I am not the kind of rookie who has just been around for a long time!" After saying that, he smiled shyly.
"Really? Then do you know where Uncle Ringo is?"
"Ringo...Uncle..." The man thought for a moment and nodded.
"I know, please come here." He stretched out his hand.
In a small digital store, a middle-aged man wearing a pumpkin hat and an unshaven beard was sitting in front of a pile of equipment, and the song "Dream Water Country" was playing on the speaker next to him.
"It's been more than ten years, but your taste in music is still the same. Hey, can you still hear it with your ears?"
"You uneducated guy, you know nothing! Haven't you heard of oidest but goodest? Old things are the most popular."
Upon hearing this, Hao Weida became even happier.
"Of course. The older our brother Ringo gets, the clearer his mind becomes and his ears become clearer. He also knows the old machines very well. What, can you figure out what they are?"
Uncle Ringo held the headset and his eyelids drooped slightly.
"It's not from E country, it's an older one. It's a model produced by S United in 1989. You might not be able to find it if you look for it. This guy doesn't seem to be someone who advocates oidest but goodest. Although he doesn't have any fancy features,
But it has the essential advantage that it is difficult to recover, and it always has this essence.”
"Hey, our brother Ringo was almost invited by the FBI when we were young. There's nothing you can't recover from."
Others may not understand it well, but Hao Weida knows his old friend's temper and strength very well. Usually he has a way to deal with what he says.
Sure enough, after debugging the equipment several times, he nodded slightly.
"Even if it is difficult to restore the original voice 100%, you can tell that it is a man. Judging from the characteristics of the glottis, he is over thirty years old and knows how to use the words of such an antique person..."
He closed his eyes, as if thinking about something.
Seeing that he had no reaction after thinking for a long time, Hao Weida quickly took out a small bottle of something from his pocket.
"Ah ha, by the way, it's a good thing to keep our brother in high spirits." He put the small bottle on the table with a smirk on his face.
That's a bottle of Viagra.
Sure enough, Brother Ringo had a smile on his face and pointed to the door.
"There is a lot of good music over there, listen to it before leaving. You will still have a headache because of this guy in the future."
He picked up the bottle of Viagra and looked at it carefully.
"Is this true?"
"Of course it's true."
Ringo looked at him suspiciously.
"Oh, I don't know. Then I haven't bought it. The store next to me says it's true, so I can only believe it."
............
"My mind will not change. As long as I do what he says, Yijia will be fine."
"Mother Yijia, it's really time for the police to intervene." Qian Cheng was still persuading her earnestly.
"The time when the ransom is handed over is the most likely time to catch the criminal."
"Didn't you hear just now? He said that if he saw the police, Yijia would die! Besides, until now, has anything you police done successfully? How can I trust you?" Rui Xiuying asked.
"Are you more willing to believe what a kidnapper says than me who has been a policeman for more than 40 years?" Qian Sen asked coldly.
"As you just said, I am the mother of my child. I must be strong and make a decision." Her tone was still firm.
"Mom?" Qian Sen sneered.
"If it hadn't been for Yijia's birth, you wouldn't have been able to enter my home! If you hadn't married into our family, nothing like this would have happened to my son and my Yijia!"
Qian Cheng turned around and left the room.
"My Yijia, what happened? Tell me, what happened to her?" Rui Xiuying stood up from the bed and looked at Qian Sen.
"Okay, even if the police have withdrawn, there are less than two hours left, where are you going to raise money?"
Upon hearing the word "raising money," Rui Xiuying lowered her head silently.
"As far as I know, you don't have such great ability." Qian Sen said bluntly.
"I think...you will help me." Rui Xiuying whispered.
"Because, just like I am Yijia's mother, you are also Yijia's grandfather."
"Humph, only at this time will you acknowledge me as your grandfather?"
Two lines of clear tears fell from the corners of her eyes, and Rui Xiuying slowly knelt down.
"No matter how many years it takes, no, even if it takes a lifetime, I will definitely give it back to you. If not, even if I sell myself, I will definitely give it back to you." Her tone was very sincere.
