Zhang Yang and Tang Youyou were sitting in the car looking at the main road around them, and at this time, a boy who drove a luxury car saw Tang Youyou in the car, and his eyes lit up. He stepped forward and asked, "Is there anything you need help with?" ”

"Police ......" Zhang Yang showed his police ID card.

"I'm sorry." The man nodded, and then drove away, his expression a little frustrated......

"After the fourth murder, the police department greatly increased its patrols in these neighborhoods, and after the fourth and fifth murders, the police department was again staffed, but the killers still did not give up and kept an eye on the houses. How did this murderer not be discovered by the police? This is unscientific......" Zhang Yang shook his head, he couldn't think of any method that the murderer could use to get out of the crowd of policemen.

"Is that a magpie?" Tang Youyou looked at a few frolicking birds on the wires.

"No, it's just a normal bird. Wait, it was said that all birds of the same sex as us have more beautiful feathers, because the males are going to try to prove their existence, and so are the murderers......"

Suddenly, Tang Youyou's phone rang suddenly.

"Hey, hello, you say.25? Okay."

Tang Youyou told Zhang Yang directly the content of the phone: "There is news from the technical department, they have located the source of the phone line through 25 different substations, each substation is possible, but we don't have much time."

Zhang Yang seemed to have thought of something.: "25, 25 sub-stations. The killer wants us to see him."

"That's right, we also pointed this out in the profile description of the murderer, what's so special?" Tang Youyou also agreed with Zhang Yang's point of view.

"Get out of the car, let's go to the scene of the case to have a look........." Then Zhang Yang pushed the door directly and entered, tearing the seal on the room in front of him, and the room was very well preserved.

"He was careful, everything that happened was within his plan and there were hardly any surprises...... He inhales the dust, and he sees it as it is about control, his creations, and he places everything the way he wants." Then Zhang Yang squatted down, the whole person lay on the bed, and then the body turned to the side, looking at the window.

"If the eyes are like that, they can see the attack, then why are their faces turned away from the attack, their eyes are in that position, they can't see the murderer, if the murderer wants to be able to see him afterwards." Directly facing the window, there are rows of high-voltage lines......

"Jiangzhou Police Department Technical Department, what do you need help with?"

"Hello, we are from the Investigation Department, we want to know, can we find out Jiangzhou's telephone maintenance records in the last three months?"

"It's not difficult, what are the characteristics?"

"I'm looking for a phone mechanic who can cross the border with a couple of recent burglary rapes, most likely four or five days before the incident, to see if there are any common names."

"OK, wait for me for five minutes, soon."

Huang Feifeng, who was squatting in society, suddenly received a call from Zhang Yang: "What's wrong, what did you find?" ”

"He's a phone mechanic, and the police are looking for runaways in the community, but who notices the mechanic on the pole, he can observe the victim's daily routine on the pole, he can see when the victim's husband is off work, watch the police patrol, know when the whole community will be quiet.

He knows when it's convenient for him, and he can even plug in one of the wires to make sure he's home, and send a phone call through 25 substations so we can't locate it.

What we have confirmed before, the tape, the wire, the type of technology, these are all ......"

"It does make a lot of sense." Huang Feifeng nodded and motioned for him to continue.

"We also looked up his name, and we're going to their office now to see where he's showing up today."

At this time, in an independent apartment in Jiangzhou, an old lady looked at her little son, with a happy smile on her face, and kept holding the bottle in her hand and said, "Baby, baby, drink a little more, eat again, otherwise you will be hungry."

The little baby kept shaking her head, and then pointed to the refrigerator with her finger, seeing this situation, the old lady turned around and opened the refrigerator, took out the little baby's favorite food, and said with a smile: "Baby, we can only eat a little, you have to eat more."

Behind "Mommy......" came the voice of the little baby.

"Wait baby, I'll see which one you eat better today." The old lady looked at the dazzling array of food in the refrigerator, full of entanglement.

"Mommy......" The little baby's voice was a little anxious.

"Don't worry, baby, you ......" The old lady turned around, and as her voice stopped abruptly, he saw a middle-aged man next to the little baby, he was holding a soup spoon to feed the little baby, and when he saw the old lady, he smiled slightly.

After knowing which technology company the murderer belonged to, Zhang Yang and others rushed over as soon as possible, and there was only one young man at the door who was recording.

"Jiangzhou Police Department, we need to know where one of your phone mechanics is......"

"Uh-uh, they're all out there, I don't know which one you're talking about?" The young man was surprised, but he still cooperated well.

"Hu Changkun, what I want is Hu Changkun."

"Wait, I'll check." The young man picked up the attendance sheet on the table, and then checked one by one: "Hu Changkun, he went to Jiahe Community, Baiyun District, Jiangzhou......"

At this time, the old lady's home was tied with her hands and feet, and the little baby sitting in the stroller looked at this scene very ignorantly.

"Please, please don't hurt my darling, my child......" the old lady collapsed to the ground, pleading incessantly.

Hu Changkun ignored her, but put on gloves, and then slowly took out his suitcase in order, wires, glue, and tape.

"As long as you cooperate, it'll be fine, trust me." Hu Changkun slowly bent down, looked at the teary-eyed old lady, and then gently wiped the tears from the corners of her eyes, put them in her mouth and tasted them, and then said with some disappointment: "It's no different, it's all a little ......."

Knowing the location of Hu Changkun's attendance, Zhang Yang and Tang Youyou rushed all the way over to the Baiyun Jiahe area on the road, and police officers from other communities also rushed to this side.

"It's his truck, his work truck." Zhang Yang and others found a truck with some circuit signs on the main road of Jiangzhou Jiahe, but there are more than a dozen houses in the surrounding community.

"Spread out, spread out, look at the houses with telephone poles around, the murderer is nearby, speed speed!"

Everyone searched the carpet in the community, but they found that the doors of many communities were locked and they couldn't get in for a while, and everyone was very anxious, like a headless fly.

At this moment, Zhang Yang passed by a courtyard and found a child's cry, he instinctively walked over to inspect, and when he walked to the door, he found that the gate of the courtyard was open and open.

The little ones shouted in the courtyard, "Mommy...... Mommy ......"
