"If the other party really came down from upstairs, how could he leave such obvious traces waiting for the police to find out? Isn't this a typical door-to-door delivery? "

Ah, Xiang stepped to the window, and the traces of soil trampled by the sole of the shoe on the window were still there. After she said so, now the footprints have really become too conspicuous.

Ah, Xiang is right.

But there's one thing he doesn't connect with.

Zhong Tianzheng asked, "if the killer swiped his card in from the door, how did he avoid the surveillance on the fourth floor?"

"Can't you just overlap the scene on the fifth floor one by one?"

Ah Xiang tilted her head and looked at Zhong Tianzheng: "the room layout on the fourth floor and the fifth floor is exactly the same. He can make a printed scene on the fifth floor to deceive the monitoring, so he can also make a scene on the fourth floor to avoid the monitoring."

"Yes!"

Yan Zhaoxing nodded in agreement.

Zhong Tianzheng leaned against the wall and didn't speak.

In my mind.

The grandmaster's spatial imagination is divergent.

A transparent apartment was quickly formed in the space. The killer came in along the fire passage, climbed the stairs quickly to the fourth floor, swiped his card into Meng Yichuan's house and hid in his cabinet.

"What about the evidence?"

Zhong Tianzheng took back his thoughts: "let's not say who the murderer is. So far, we haven't found any clues left by the murderer. What should we do?"

"You once said that as long as the murderer enters the crime scene, even if he handles it well, he will leave something. Equivalent material exchange, you said."

Ah Xiang shook her head and began to check in the room: "there must be some news clues at the scene that have been ignored by us. The murderer must have left something."

Meng Yichuan's room is very simple on the whole.

Perhaps because he is a person and has a light and easy-going style, there are not many items in the room. Apart from the wardrobe and desk brought by the apartment itself, there is no other place.

"The only place to hide people is under the bed and in the wardrobe."

Zhong Tianzheng came to Meng Yichuan's bed, bent down and looked under the bed.

There is a rolled up mat under the bed, and there are two luggage bags. There is a layer of dust under the bed. Zhong Tianzheng turns on the flashlight to take photos. The dust is very flat and there is no trace on it, which shows that no one has been there at all.

This way.

Yan Zhaoxing opened the wardrobe.

"Meng Yichuan should seldom use this wardrobe."

Yan Zhaoxing commented lightly: "most of the clothes hanging inside are mainly winter clothes, and the rest are thicker sweaters and so on, which can't be worn now."

So far.

This is the only place where people can hide indoors.

"However, there is no abnormal trace."

The three men looked around the wardrobe for a while and searched carefully. They didn't find anything like hair. It's very clean.

"Did you guess wrong? The killer didn't enter the room in advance? "

Zhong Tianzheng and Ah Xiang looked at each other and held a skeptical attitude: "since the murderer can avoid monitoring, he can wait for Meng Yichuan to take a bath in the bathroom, swipe his card directly and commit the crime."

This also explains why there are no traces left by the murderer in the room.

"I think the killer came in early."

Ah Xiang shook her head and denied it. She tilted her head to the anti-theft door and pointed to the anti-theft door: "the sound insulation effect of this anti-theft door should be very good. You can't hear the sound in the room when you stand at the door. In other words, you suddenly open the door and come in. How do you know what the people in the room are doing?"

"In addition, there is a sound when swiping the card to open the door. The secrecy is too poor. It's much more real than hiding in advance."

"Well..."

They answered and didn't speak again.

Then he turned and walked into the bathroom to see if there were any clues he could find.

Ah Xiang continued to stay outside.

"Ceiling?"

Zhong Tianzheng stood in the bathroom and looked at Yan Zhaoxing who was looking at the bathtub. His eyes turned to the ceiling above his head: "hide above?"

He casually took the chair on the side as a support, stepped on the stool to open the ceiling above, and the flashlight shone in.

The conjecture was immediately dashed.

The inside is very normal, and the dust accumulated on the surface has no touch trace.

"Hey!"

Just then.

Outside, the sound of incense sounded: "come and see here."

"Anything?"

Zhong Tianzheng glanced at Yan Zhaoxing and turned to the outside.

Ah Xiang squatted on the edge of the wardrobe, pointed to the bottom cabinet board under the wardrobe and said, "look here, do you find anything abnormal?"

Follow the direction pointed by Ah Xiang's finger.

This wardrobe belongs to the kind of rough processing. The inner layer of the cabinet is not painted or sealed on the surface. The bottom cabinet board of wood primary color is dark yellow as a whole, with a little black mildew.

"Nothing is abnormal."

Yan Zhaoxing looked carefully and replied.

Ah Xiang then looked at Zhong Tianzheng.

Zhong Tianzheng also looked carefully, shook his head and denied, "there's nothing wrong."

"Two straight men."

Ah Xiang silently Tucao a sentence, took a flashlight to make complaints about the lights.

Zhong Tianzheng and Yan Zhaoxing said nothing to each other.

Why is this related to straight men again?

Under the light.

The board looks clearer in the field of vision, but there is still no difference in the overall view.

"Look here."

Ah Xiang pointed to the middle of the bottom plate: "here, do you find that the color of this place is darker than that of other places? Even a little faint crimson? "

"Well..."

Zhong Tianzheng and Yan Zhaoxing pondered, "no..."

“……”

Ah Xiang turned her eyes at them helplessly: "I guess it should be menstrual blood..."

"What?"

Yan Zhaoxing was speechless: "why is this thing here?"

"Do you know what side leakage is?"

Ah Xiang's face turned slightly red and explained to the two: "maybe it was a coincidence when the murderer hid here. Her aunt came and she didn't know, so she didn't bring her aunt's towel. The blood soaked her pants and left a little trace on it."

"In other words, it was leaked from the side of my aunt's towel."

No. "

Yan Zhaoxing thought seriously: "if it's aunt's blood, shouldn't it be dyed red on a large scale? Instead of leaving such a thin trace? "

"Straight male cancer!"

Ah, Xiang silently rolled her eyes: "please, you think this thing has been bleeding like cutting the main artery! It came in bursts... "

"All right."

Yan Zhaoxing looked half ignorant and didn't speak again.

Ah Xiang added: "the most important thing is that Chen Jiani is also in the period of great aunt..."
