Following the direction of Zhu Xingxing's finger, Zhou Ning looked over.

On the shoes, there were two water drop-shaped stains, not large in size, but they were all in the gaps on the front edge of the shoes, slightly stained with dust, and the colorful patterns were not so eye-catching.

Seeing that everyone was just watching, Zhu Xingxing didn't react too much, so he said anxiously:

"Oh, I don't like to drink sweet things when I look at a big man. I like to drink milk tea and milk, and I often touch my body. The color of these traces will be slightly yellow. I think it's milk stains."

Da Zhao was a little skeptical, so he leaned over and took a look.

"You also said that girls like to drink sweets. Isn't she also a girl? It's normal to get shoes on, right? And at Zhang Bo's house, we inspected the scene carefully and found no shoe prints on the ground other than slippers. If you wear this to go in , how can we not leave footprints?"

Zhu Xingxing raised the shoe and sniffed it, not caring about it at all, and then said firmly:
"I insist on my opinion. I think these two traces are milk stains, and it's that kind of formula milk. Although I didn't go to the scene, I trust my sense of smell. This kind of milk is very sweet. If you don't believe me, smell it."

Zhou Ning waved his hand.

"Pack up the shoes, take them back for sampling and comparison, and thoroughly inspect the room to see if there are any other traces left."

Zhu Xingxing raised his chin towards Da Zhao. Zhou Ning's approval made her very happy. Everyone began to search the room separately. In fact, they could clearly feel that the room had been cleaned thoroughly, and the marks of water stains dried up when mopping the floor were all left on the floor.

Zhou Ning did not go to each room, but stood in front of the shoe cabinet, put on gloves, the entrance door was open at this time, Liu Yufei and Ye Chengchen were standing in front of the elevator, she could see all the movements here .

Turning around and glanced at Ye Chengchen, seeing Zhou Ning looking over, she quickly averted her gaze.

Zhou Ning turned around and thought about it. Ye Chengchen's evasive gaze was an expression of trying to restrain herself. She was very nervous. So, does it mean that there is something she wants to hide in her position?

Or was he in a hurry and forgot to cover up?

Thinking of this, Zhou Ning opened the shoe cabinet, which was full of shoes, and the two shoe cabinets, which looked like large wardrobes, were filled to the brim. Da Zhao was able to find the pair of old shoes all at once, which is really amazing.

After scanning up and down, he didn't see anything special. Zhou Ning opened the middle drawer of the shoe cabinet. There were two drawers. One was full of shoe brushes, shoe polish and shoe polish, and the other was full of various bags, silver and silver. Ionic deodorant, and several boxes.

Open the lid of the box, and there are bags of various fragrances inside.

Not to mention, the life of a model is exquisite, and there are so many things to say about deodorizing shoes. As Zhou Ning opened the last box, some bundled shoe covers inside caught his attention.

Zhou Ning turned around suddenly and looked at Ye Chengchen at the elevator door, and Ye Chengchen was also lowering his head, secretly looking at Zhou Ning, so her prying gaze was caught by Zhou Ning.

It seems that this is one of the reasons why she doesn't want to be searched. There are guest slippers in the house, so why are there so many shoe covers, and it seems that only one bag has been opened.

Zhou Ning didn't speak, shoe covers - old shoes - footprints - milk stains
Could it be that after Ye Chengchen disguised himself, he went to the fifteenth floor from the corridor and waited for Zhang's mother to go out before going to Zhang Bo's house. In order to avoid the police's search and leave no traces, she put on shoe covers and slipped them into slippers , in fact, as long as the slippers are big enough, this kind of operation is also possible.

However, how to explain the milk stains?

Zhou Ning frowned, closed his eyes slightly, and tried his best to change the scene.

In front of him is already the entrance of Zhang Bo's house.

Slightly bowed his head, those old shoes with shoe covers, stepped on the slippers when he entered the door, pulled the slippers, entered the baby enclosure area of ​​the living room, stepped in, picked up the boy, but the shoes were too big, The child was also crying, and the baby bottle in the child's hand was knocked over.

The milk was directly poured into the inside of the slippers, but there were no milk stains on the surface, so she carried the child by the waist and walked straight to the master bedroom.

Then he and Zhang Bo carried a child, went straight to the master bedroom, and threw it out towards the window. However, the boy struggled fiercely. Before he let go, his head was already facing down. The hand with long nails wanted to adjust the direction and grabbed the boy's thigh. , but at this time the child also let go.

In a hurry, the person holding the slippers ran to the door quickly, took off the slippers, only to find that the outside of the shoe cover was a little wet, but he didn't care, pulled off the shoe cover and held it in his hand, and walked away quickly.

Zhou Ning opened his eyes, and he fell silent. Da Zhao and the others came out after the investigation. Seeing Zhou Ning's serious expression, everyone was a little puzzled. Zhou Ning closed the door of the shoe cabinet.

"Have you found anything?"

Da Zhao held up several physical evidence bags and said while introducing:

"The residues in the vacuum cleaner and on the mop were all extracted, and some short curly hairs were found, which seemed to be pubic hairs. In addition, the lip prints on the edge of the cup were collected. It was not lipstick, and nothing else was found."

Zhou Ning nodded, he understood Da Zhao's meaning, glanced at the hair, it should be male, he waved his hand directly.

"Go directly to Zhang Bo's house on the [-]th floor and let Liu Yufei and the others wait here. Let's go!"

After speaking, everyone went out, and Liu Yufei naturally heard their conversation, so she hurriedly said.

"We have closed Zhang Bo's house. Ma Liang is staying at the door. You can go up directly."

Zhou Ning didn't talk nonsense. He didn't take the elevator with the people. This time he went straight up the stairs. As the door of the safe passage was closed, he could still hear Ye Chengchen's voice, his sharp voice, protesting constantly, but nothing could stop him.

Da Zhao leaned next to Zhou Ning, blinked and asked:

"Zhou Xiaozhou, did you find something?"

Zhou Ning shook his head.

"It's not a discovery, but a guess. During the process of going upstairs, carefully look for the footprints of Ye Chengchen's old shoes. Look for the photos. It doesn't mean that the shoe prints were also found in the stairwell on the fifteenth floor. "

"Well, I just did a comparison, and the size and pattern are exactly the same, but this doesn't prove anything, it can only mean that Ye Chengchen once stood there."

Seeing that Zhou Ning didn't speak, Da Zhao didn't nag any more. He dragged Lao Yang and Wang Henjian to search carefully all the way, and indeed found a few shoe prints of Ye Chengchen at the corner of the steps.

All the way to the fifteenth floor, Xiao Zou and Xiao Pang were already panting, and Da Zhao gave them a white look.

"I said to exercise. I climbed seven floors. I didn't come up in one breath, but I was panting like this. Can you do it? Are you suffering from kidney deficiency?"

Zhou Ning slapped Da Zhao, and Da Zhao shut up. Sure enough, at the door of the stairwell, he saw four or five shoe prints, and the edges were circled by Da Zhao with chalk. It seems that people really don't come here often. A day later, the chalk marks are still intact.

Zhou Ning stood behind the shoe prints and looked towards the elevator on the fifteenth floor. The doors of the two houses and the elevator door can be seen at a glance. Sure enough, this is a very hidden corner, and you can find the movement on this floor at any time.

"No one lives in 1501?"

"Well, the owner of 1501 went abroad. We contacted the property that day and asked about the situation."

Zhou Ning pushed the door and came to the door of 1502. Ma Liang jumped on the pony and got up quickly.

"Director Zhou, you are here, I will open the door for you."

"Did the Zhang family come to make trouble?"

Ma Liang shook his head.

"Zhang's father and Zhang's mother came over to pick up something. I asked someone to take it for them. Some neighbors came to peek, but they were all dismissed. No one else came around."

As he said that, the door of the room was opened, and a faint fishy smell came out.

When I came in yesterday, it seemed that the window was open, so I didn't notice the smell. Da Zhao rubbed his nose and bumped Zhu Xingxing.

"Well, do you smell the fishy smell?"

Zhu Xingxing gave him a blank look.

"I'm not stupid. I can't smell such a pungent fishy smell. I can still smell milk, a very familiar milk smell."

Zhu Xingxing didn't come to the first scene yesterday, so Zhou Ning was a little surprised.

"Okay, let's start to investigate again. Check the slippers carefully to see if there are any shoes with milk on them. I'm not talking about the soles, but the inside of the shoes."

"inside of?"

Zhu Xingxing kicked Da Zhao, gritted his teeth and said:
"Whatever the boss says to do, just do it. Why are you talking so much nonsense? Hurry up and investigate, I smell the shoes."

Da Zhao rubbed his nose, dressed obediently, and entered the room. Zhu Xingxing and Zhou Ning were left at the door. Zhu Xingxing crossed his fingers and squeezed the air out of his gloves before squatting down to check his slippers.

There are a lot of slippers under the shoe cabinet, only a pair of red ones looks relatively small, Zhu Xingxing picked it up to look at the soles, and then put them aside, these soles obviously have traces of sampling.

Zhu Xingxing began to check the slippers one by one. He looked around all the slippers on the ground, and none of them had milk stains on them. Zhou Ning frowned slightly. At this time, he was a little doubtful whether his guess was in the right direction.

At this moment, Zhu Xingxing opened the shoe cabinet and found that there were still slippers inside, but these were thicker cotton slippers, and she didn't dislike the strong smell of sweaty feet, so she sniffed it closer and let out a hush .

Zhou Ning quickly squatted down and got closer, following Zhu Xingxing's gaze.

"Find the smell?"

Zhu Xingxing glanced at Zhou Ning with a hint of grievance.

"Boss, are you using me as a police dog?"

Zhou Ning was a little embarrassed. Before she could say anything, Zhu Xingxing had already pulled out a pair of shoes with a smile, lifted them up and pointed to a shiny thing and said:
"Look what I found?"

Zhou Ning glanced at it, and it seemed to be a metal iron chain with two bows. Using the adjective Xia Momo often said, it was Bling Bling's. It looked very shiny, but is this a decoration for slippers?
"What are these, the slippers look very rustic, are they pasted on purpose?"

Zhu Xingxing shook his head and lifted the slippers.

"I was drawing blood for Ye Chengchen at the time, and Da Zhao cut her nails. I remember that there was something like this on her nails, but one was missing on her left hand. It seems that it was scratched here, eh! Boss , These shoes smell of milk!"

Zhou Ning was a little excited, and looked down, but the naked eye could see no trace of milk.

"you sure?"
