Chapter 545 A Single Man Without a Wife

Xingyue Road.

Jiang Yuan patted Pang Jidong awake and said, "Pang Da, it's here."

Pang Jidong said "ah", wiped the corners of his mouth, slid out of the car habitually with blank eyes and submissive hands and feet, and asked, "Which side."

"Here we are." Jiang Yuan pointed to a single-family villa in front of him.

Pang Jidong said "Oh", like a tourist who had been pointed out by a tour guide, and followed the large group to the place.

When they arrived at the place, the large troops took pictures and videotaped videos, and some people came forward to knock on the door, showed up, and explained their identities.

Pang Jidong glanced back, waiting for the tour guide Jiang Yuan to start explaining.

As far as the teaching time is concerned, Pang Jidong has learned it.

Jiang Yuan really didn't give up on Pang Jidong's just waking up period, seized the time, looked around, and said: "The type and quantity of pollen and spores we extract from the sample depend on many variables, we call it 'burial' "Scientific factors', this is a proper term, referring to all the factors that determine whether the sporopollen can be found at a specific time and a specific place..."

"For example, why do we have to come to the scene of the crime to compare, because the terrain of the crime scene is different, and the spread of pollen will be different. Don't look at wind pollen, which can spread very far, but any building Plant and plant barriers can prevent their spread..."

"Like a high wall here, it can stop most of the pollen from spreading."

"In this way, like the pear tree here, when it blooms, the flowers will fall on the ground, and centered on the tree, it will spread out in circles, and the pollen is the same, the farther the distance Yes, less pollen."

"There's a problem of decentralized efficiency here..."

Jiang Yuan said as he walked, it didn't take long for Pang Jidong to feel dizzy and unable to walk.

Jiang Yuan sighed and ended the teaching work for this period.

It has to be said that Pang Jidong's speed of accepting knowledge has obviously slowed down. It is like a grinder that used to grind 500 grams each time. After using it for a while, it can only grind more than 400 grams. A continuing downward trend.The battery is not used as an example because Pang Jidong's mental decline is not so fast.

Jiang Yuan handed Pang Jidong a thermos cup, and said with concern: "Drink some water and take a rest."

Hearing the rest, Pang Jidong took the thermos cup, gulped down a few mouthfuls, then wiped his mouth, frowned and said, "Sugar water?"

"Sugar can increase memory and improve concentration. Drinking it properly will help you learn new things." Jiang Yuan used all his biological knowledge.

Of course, sugar also makes people fat and can lead to problems like diabetes, but when it comes to learning, eating sugar is good.

Pang Jidong also felt that he should make up for it.

After drinking the sugar water provided by Jiang Yuan, Pang Jidong blinked, feeling a little more energetic.

Just a little bit, but at least it's not a pure fainting state anymore.

At this time, the policemen in front had already filed into the single-family villa.

The villa has three floors, plus a basement, and a yard surrounded by villas on three sides, with bamboo planted all around, and the privacy is quite good.In theory, if you want to bury the corpse, such a yard is more convenient.

Many serial killers in foreign countries will bury their bodies in the yard, probably because this method is the most friendly to novices, and it can train a murderer from scratch.Domestic conditions in this regard are somewhat lacking.

Of course, many of the villas near Xingyue Road that are running today have potential.

Jiang Yuan pulled Pang Jidong up, followed by Mu Zhiyang, who knew the way first went to the backyard to see.

A total of four to five hundred square meters of backyard makes the distance between the house and the house very wide, planting a lot of roses, roses and other Rosaceae plants, several kinds of shrubs, plantain and clover on the lawn...

Jiang Yuan's eyes swept over, and his attention gradually increased.

Although most of them are some common plants, the varieties are already relatively similar.

Using the "burial factor" that Jiang Yuan told Pang Jidong, as the second transfer of pollen, this place can already be regarded as suspicious.

While doing mental calculations, Jiang Yuan cast his eyes into the distance.

Through the low wall and the not very dense bamboo rafts, you are the next door. The plants next door seem to be different, but if you look closely, it is nothing more than a little less variety, freeing up more space for tables, chairs and benches. There are also things like game consoles for leisure.

Jiang Yuan took a few steps forward and got closer to the next door, and saw a small pile of fallen leaves and grass clippings in a corner of the yard.

"Where is the head of the household?" Jiang Yuan called the head of the household of the villa here, and asked: "There are a lot of fallen leaves and the like in the yard next to you. I think some of them are rotten. Don't you think it stinks here?"

The head of the household is a man in his 40s. Seeing Jiang Yuan asking this, he immediately frowned and said, "I've said it several times, and every time I said it, he cleaned it up, and it piled up again after a while, and the property was searched once. It's useless, and the good neighbors don't talk anymore."

"So he has piled up fallen leaves all year round."

"It's about the same. It's better when the weather is cold, but it stinks in summer, so you have to urge him to clean up." The head of the household shook his head: "Those who still want to buy a villa, the quality can be better, no, now people are Don't talk about anything."

"Okay, I see." Jiang Yuan sent the head of the household away, and said to Mu Zhiyang who was waiting next to him: "Go and see the next door. Don't leave alone, a few more people go."

Pang Jidong, who was still recharging his energy, widened his eyes when he heard what Jiang Yuan said.

"Did you find anything?" Pang Jidong's brain was filled with the candy he had just drank.

Jiang Yuan said "En", and said: "Do you remember the cylindrical spores in the laboratory I showed you? The light brown one."

The corners of Pang Jidong's brows drooped just now, are you tricking the dog to come to class?
Jiang Yuan coughed twice, and said: "In short, this kind of spores usually appear on rotting fallen leaves and tree debris, such as birch, holly, oak and other leaves, like to grow this kind of fungus."

Jiang Yuan whimpered, and continued: "The leaves are mostly birch and holly trees, and these trees are planted around his house. Of course, the focus is not on the trees. The spread range of fungal spores is relatively close, although there are everywhere. Rotten leaves, or dead wood, but fungal spores are still very indicative, because it usually requires direct contact to transfer. That is to say, the dispersion efficiency is very low, and it is a more meaningful forensic marker.”

"Understood, I'll go and arrest people." Pang Jidong turned around and left, his movement speed was not inferior to that of Mu Zhiyang and others.

At the same time, several other criminal policemen went out from the back door here, went around to the back door of the villa next door, did not go in, and squatted there.

What they want to see the most is the people from the villa next door, running away at once.

If this is the case, even if no one is caught, everyone will be happy.Because it proves that the suspect is identified.

However, such a beautiful thing did not really happen.

When Jiang Yuan passed by again, he saw a man in his 30s who looked like a career elite, smoking a cigar slowly in the empty living room.

"Single men without wives can smoke at home, so cool." Pang Jidong waited for Jiang Yuan to come over, and he couldn't help but sigh with emotion.

"Live alone in such a big villa?" Jiang Yuan raised his head and glanced. The gap between the two floors is more than 7 meters. If he stays at night, it will only get darker and darker. He has a deep understanding of this kind of house, otherwise When I bought a house for myself in Changyang City, I didn't buy such a small house.

Pang Jidong naturally took it for granted: "It's somewhat evil."

At this time, the single man without a wife who was sitting on the sofa raised his head and said with disdain: "I know that the police in your interior don't follow the rules, but I am a Malaya nationality, so please pay attention."

The criminal police present couldn't help looking at Pang Jidong and Jiang Yuan.

"Take it back." Jiang Yuan had already seen the backyard just now, and now he has seen the interior and the owner himself, without hesitation at all.

Pang Jidong didn't say much, he chopped his hand and repeated the order: "Take it back. Be polite."

The single man without a wife frowned and looked at Jiang Yuan: "You idiot, do you have evidence?"

Jiang Yuan waved his hand in disgust, refusing to reveal any information to him.
