The two sides had to exchange information.

It was not convenient to discuss in the food stall, so Ji Feng approached Jian Jing and whispered the latest investigation in her ear. The boss was sitting opposite and pretended not to see it.

As a result, Jian Jing was "leaked" smoothly.

Cigarette ash and field soil... She silently recited the two clues and searched for corresponding points in her mind: "The workers smoked, and the brand was not the one you said. State-owned enterprise employees do not smoke, and his teeth have no traces of being smoked by smoke. Field soil is even more difficult, everyone has a potted plant."

Ji Feng immediately had a stomachache and quickly drank two sips of hot noodle soup to warm her stomach.

Jian Jing picked up a piece of rice noodle but didn't eat it. She tied a knot on the chopsticks and pondered, "Why is it frozen to death?"

"Of course it's for the sense of ceremony." Liang Yi said, joining the group chat with great interest, "Long wavy hair, frozen to death, both have special meanings to the murderer. What do you think, you have come into contact with this kind of guy?"

Jian Jing shook her head: "I can't say."

Liang Yi: "Just talking."

"I haven't seen the body, nor the photo." She asked resentfully, "What do you want me to say?"

"Uh." Liang Yi said

embarrassedly, "That's right." Jian Jing poked her head out: "So, you will investigate them tomorrow, right?" "

Of course." Liang Yi raised his eyebrows. Although his eyes were full of bloodshot, there was a stubbornness between his brows, and he was more energetic than the men present.

Jian Jing came closer, as if she was telling a secret to a close friend: "Take me with you?"

Liang Yi blinked, didn't respond, didn't refuse, but wanted to agree.

The previous cooperation with Jian Jing was quite pleasant, and the girls were more comfortable to communicate with each other. Unlike the others, Captain Wang felt that she was young and needed more care, and Brother Zhao thought he had more experience and didn't pay much attention to her ideas. Ji Feng, who was about the same age... forget it, this guy was so lazy.

"I'll ask." She winked.

Jian Jing made an "OK" gesture.

Ji Feng: "..."

He pretended not to hear it with amusement.

The meal was quickly finished, because it was dinner for Liang Yi and the other three, and everything was cleaned up in less than ten minutes.

Liang Yi was so focused on solving the case that he kept his eyes on the distance. When he saw the maintenance worker was about to finish his bowl of noodle soup, he immediately asked, "Captain Wang, can I go over and take a look?"

Captain Wang said, "Oh, you go back and have a rest, and ask Xiao Ji to follow you."

"It's okay, I'm not tired." Liang Yi hated being "taken care of" by others the most, and was so anxious, "Let me go."

Brother Zhao also put down his chopsticks, "I'll go with Xiao Liang."

Captain Wang agreed, "Okay, then Xiao Ji will go back first today, and we'll take turns tomorrow. You are young, but you should also take care of your health."

Liang Yi said "hmm" twice to fool around, and quietly merged into the crowd, and followed behind Suspect No. 1.

Captain Wang glanced at Ji Feng, "Send him off."

Ji Feng said weakly, "Got it."

The leader left with satisfaction.

As soon as he left, Ji Feng came alive again: "Let's chat?"

"I'm tired." Jian Jing stretched her back and patted the knight who was chewing on the roasted lamb leg (without seasoning). "Let's go home."

She got up and left. The knight had to reluctantly let go of the bone in his mouth, dawdling and looking back every few steps.

Ji Feng looked at the unmoving fried rice noodles and asked: "There is a bakery halfway around the corner. Do you want to go?"

"Is it still open so late?"

"Yes."

The bakery was indeed open, the storefront was bright, and the remaining bread was on sale, which was a great deal. Ji Feng bought a large bag of bread, just enough for tomorrow's breakfast.

Jian Jing picked and chose, and chose a matcha pound cake, packaged it slice by slice, and put it in her pocket so that she could eat a piece at any time.

She stuffed a few slices into Ji Feng's hand: "Bring them to Liang..."

"What?" He pretended not to hear, opened the package and stuffed them into his mouth, "Not bad, not too sweet."

He stuffed the rest into his coat pocket.

Jian Jing narrowed his eyes: "What do you mean?"

He clicked his tongue and said: "Don't you think about it? I wrote the report and I spoke for you, otherwise you wouldn't have heard it. But you took advantage of me and got together with Liang Yi. Where's your conscience?"

Jian Jing: "Get lost."

The two were about to argue when Ji Feng's cell phone rang. He picked it up and laughed: "Lucky."

"What?"

"My aunt went to deliver the report to the colleagues in the anti-pornography team." He said, "Okay, I'll pick you up tomorrow morning, see you downstairs."

Jian Jing reacted and immediately regretted: "Yes, if I had known I would have..."

Well, suspect No. 1's hobbies are not harmonious, and he went to the hair salon yesterday. If I had called the police at that time, I could have visited his house today.

Mistake, misstep, not as skilled as Liang Yi.

"Don't break your promise." Jian Jing was very concerned about the case and warned.

Ji Feng: "Teacher Jian, I'm not such a bad person."

"Haha."

Facts proved that Ji Feng was not so bad.

The next morning, he called Jian Jing three times in a row and dragged her out of her house: "I'll be downstairs in five minutes."

"Ten minutes, I still have to eat breakfast." She said.

"I brought you buns and soy milk." Ji Feng said, "Seven minutes."

Jian Jing: "I don't want buns."

He glanced out the car window: "Steamed buns?"

"I want to eat pan-fried buns." She said.

Ji Feng thought to himself, where can I find you some fried dough sticks? "How about egg pancakes? With fried dough sticks."

"Fried pancakes," she said, "with crispy biscuits, potato shreds, pork floss, peanuts, and more sauce."

Ji Feng compromised, "Okay."

So he spent eight and a half minutes to get to her house, picked up Jian Jing who was tying her hair while going downstairs, and headed straight to the destination.

The maintenance worker's surname is Dong, so let's call him Dong Gongren, and he lives in the urban-rural junction.

The house price here is low, the management is chaotic, and the environment is also relatively bad.

Jian Jing put on the hood of her sweatshirt and walked carefully on the streets full of sewage. It rained late last night, and the garbage and rainwater mixed together, giving off a bad smell.

Couriers, takeout workers, maintenance workers, and laborers...busy figures shuttled through the streets and alleys, supporting the convenient urban life.

Worker Dong lived on the top floor of a self-built residential building. The landlord came to open the door, but did not ask what the tenant had done wrong. He coldly said "Don't mess it up" and hurried off to play mahjong.

Ji Feng entered the house and first swept the environment. It was a little dirty.

The sofa was full of stains and had several holes burned by cigarette butts. The ashtray was full of cigarette butts, and white ashes were thrown out and scattered on the ground.

"Several brands of cigarettes." Jian Jing also noticed this. "Yours only has one kind of ash?"

Ji Feng nodded.

He went into the bedroom again. There was a torn quilt and several cardboard boxes. There

was no balcony to dry clothes. All the clothes were hung outside the window. Jian Jing walked into the bathroom. It was very narrow inside. There was only a shower area and not even a bathtub. It was very simple. She couldn't help wondering: "There is no place here where people can freeze to death, right?"

"Do you think people can only freeze to death in the ice and snow?" Ji Feng asked.

She frowned.

"All the cold storages in the city have been investigated, and the cold chain vehicles have also been checked." He said slowly, "Besides that, is there any way to freeze a person to death without alerting anyone?"

Jian Jing pondered: "If you have to say, humidity will do."

People don't necessarily have to be in a cold environment to die of hypothermia. If the temperature is around 0 degrees and the body is wet, the body temperature will also be lost rapidly until death.

"Wanyuan's body may be different. The other three female bodies, the body spots are mainly deposited in the lower limbs."

She raised her eyebrows: "Did they die while sitting?"

Ji Feng nodded and added: "There was a little bit in the upper body, but it was relatively mild. They died while sitting and were later laid flat. Therefore, the place where the murder took place should be relatively small."

For example, this kind of family bathroom.

Jian Jing thought: "□□?"

"Here." Ji Feng was tall and flipped open the water and electricity meter on the wall.

In order to facilitate billing in this kind of rented house, the water and electricity are separated, which is convenient for him. But after counting, he shook his head: "Not much."

So, Jian Jing went back to the original question: "The place is so small, why was she frozen to death?"

"My aunt said that the murderer must have been abused by her stepmother when she was a child and almost frozen to death, so she is still brooding over it." Ji Feng joked, "You are still waiting for her. She checked the hair salon yesterday and is already checking the missing lady today."

Jian Jing supported his forehead and said: "If it is true, it is too classic."

He nodded slightly: "That's what is strange."

Thanks to various movies and TV dramas, people are no strangers to perverted murderers: they specifically target dirty lower-class women, have special codes, and are eager to become famous and get a special title... There are too many of them.

But are there so many such people in reality?

In a year and a half, Jian Jing solved so many cases, but only encountered one Wang Shi.

"Let's go to No. 3's house again."

Suspect No. 3, a state-owned enterprise employee, surnamed Zhu, is the office director and is called Director Zhu. He works from 9 to 5 and works very late. When the two arrived, he had not yet gone to work.

Director Zhu was surprised: "Excuse me, what can I do for you?"

"I want to ask you a few things. Can I come in?" Ji Feng asked.

Director Zhu hesitated for a moment, opened the door to let them in, but said: "I have to go to work soon, can you hurry up?"

Ji Feng said: "Just a few questions."

He said: "What is it?"

"Have you seen any suspicious people around recently?" Ji Feng asked.

Director Zhu was very cautious: "I get home quite late from work every day, and I haven't paid attention to the area around me. What happened? What is considered suspicious?"

"Is there someone who is unfamiliar and is sneaking around to get information?" Ji Feng fooled him.

Director Zhu thought about it and shook his head: "I haven't encountered him before."

They asked and answered each other, and Jian Jing walked around the living room for half a circle, investigating Zhu's home from all angles.

His home is a typical two-bedroom, one-living room, and one-bathroom layout. The kitchen is fully equipped with oil, salt, sauce, and vinegar, and the tile countertops are glowing with a faint light, which shows that they are often used. She

peeked into the bedroom again, and there was a large bed and two pillows neatly arranged.

She looked for a while longer, and then glanced at the bathroom.

The place was also small, but there was a bathtub, shampoo and shower gel bottles were displayed on the shelf, there were two toothbrush cups on the washstand, and a storage rack hung on the wall, which was difficult to pick up and look at.

Jian Jing winked.

Ji Feng stood up, walked to the TV cabinet, and picked up a photo on the side: "Excuse me, are these your children and your wife?"

"Yes." Director Zhu followed unconsciously and said, "This was taken when my son graduated from junior high school and our family went to Sanya."

Jian Jing took the opportunity to take down the air cushion comb on the shelf and combed the teeth carefully.

Clean and tidy.

Ji Feng was still asking, "Has your wife mentioned anyone recently?"

"She went back to her hometown," Director Zhu said, "My son is out of town, I really don't know."

He looked at the watch on his wrist, and seemed to be shooing away the guests: "Sorry, I'm at work, you see..."

Ji Feng said straightforwardly, "Sorry to bother you."

He said goodbye to Jian Jing, pretended to go to the next building to ask, but quietly hid in a corner, and only asked about the neighbors after Director Zhu walked away.

But this time, he was the one being asked.

The community was neither new nor old, and the neighbors didn't know everything about him, but they also didn't know everything about him.

"Director Zhu? I know him. He's a nice guy. He's always smiling and polite. He cares about his family. He often buys groceries after work. His wife is very busy with her business and doesn't come home until late at night."

"What's the relationship between the couple? Well, it's hard to say. Sometimes they quarrel. I live downstairs and sometimes I hear some noise. But who doesn't quarrel? I didn't pay attention."

"His son is rarely seen. He must be studying in another place."

"What date did his wife go? I don't know. Was it the 1st or the 2nd?"

Everyone was talking at once, providing a lot of information, all in a mess.

Ji Feng asked, "Teacher Jian, what do you think?"

Jian Jing pondered, "There's something strange."

He: "?"

"The combs they have are so clean."
