At noon, Professor Lei and his entourage came to the scene of the No. 2 case, a wasteland behind the train station.

Han Li also brought Qian Fugui over, but he didn't dare to approach at all when he stood far away, and he shrunk his neck and was afraid like a newlywed daughter-in-law.

Sophie clenched her fists and walked to Qian Fugui without smiling.

"Little friend, I heard Han Li say that you are my long-lost boyfriend, is it true?"

"No, no, no, I ...... I'm kidding, kidding. Qian Fugui was embarrassed and couldn't wait to find a hole to drill.

"What do you call it?"

Sophie offered to hold out her hand.

"Qian Fugui, just call me Fugui'er, take care of me in the future." Qian Fugui hurriedly shook Sophie's hand.

Sophie smiled on her lips, but her hand was violently exerted, Qian Fugui's hand was instantly deformed, and her grinning face turned green with her teeth in pain.

"What's wrong? Is my girlfriend not gentle enough? Sophie said with a smile.

"No, big sister, I was wrong."

"Big sister?"

Sophie exerted her strength again, and this time Qian Fugui couldn't hold back anymore and cried out in pain.

"Little sister, it's young sister, young sister, I was wrong, I won't talk nonsense in the future."

Everyone was amused and laughed.

"Boy, I'll kill you if you talk nonsense in the future, let's go, I'll introduce you to everyone." Sophie glared at the frightened Qian Fugui and retreated again and again.

His hands were pinched and deformed, and he gasped in pain and shook his hands.

"Alright, don't make a fuss." Professor Lei stopped in time and took the initiative to introduce Qian Fugui to everyone, "This is Qian Fugui, a new member of our special case team, although he is only a trainee police officer now, but he has lived in the police dog base since he was a child, his sense of smell is different from ordinary people, and he knows animals very well, especially dogs, he is an animal expert, his grandfather is also our old-timer, a retired old police officer, Qian Fugui followed his grandfather to solve the case when he was very young, and has quite rich experience in solving cases." ”

"Does he have a smart nose?" Sophie asked with some suspicion.

"Have you ever heard of the 309 robbery in Ordos? Four robbers ransacked the local wool trading market, leaving only one piece of clothing at the scene, Xiao Qian just sniffed it and locked up one of the milkmen among the robbers, and finally helped the police catch the robbers, it took only five hours, it is not an exaggeration to say that it is a dog's nose, and everyone will learn from each other in the future. Professor Ray said.

Zhang Zhang waved his hand and smiled: "Don't say that, I am his apprentice, where do I dare to let him learn from me, I will learn from him almost the same." ”

"What apprentice?" Professor Lei was said to be confused, Zhang Li's education is much higher than that of Qian Fugui, when did he become Qian Fugui's apprentice?

"Just kidding, it's all a joke, Brother Li, I was wrong, I won't blow it again."

"Don't, we still have to listen to you blow it today, let's talk about the case." Zhang Li said with a smile.

Professor Lei also nodded, indicating that Qian Fugui could speak.

Qian Fugui repeated his opinion, he raised his hand and pointed to the distance, and said: "I'm sure that is the place where the crime occurred, and the bones are buried in the construction site, maybe the rest is in this place, so I brought my good brothers with me." ”

Saying that, Qian Fugui shouted not far away: "Black Dragon! ”

I saw a black back rushing out of the grass, like a black whirlwind, the body stretched, the limbs galloped very fast, and in a blink of an eye, he ran in front of Qian Fugui, threw himself into Qian Fugui's arms, and kept whispering.

Qian Fugui rubbed his black-backed head and introduced it to everyone: "It is my good brother Black Dragon, it has been with me since birth, we have eaten in a bowl, it is a police dog, it is our comrade-in-arms, Black Dragon, give everyone a salute." ”

The black dragon raised his front legs and stood up like a human being, and yelled at everyone twice.

Everyone was amused by it.

"Hahaha, I like it." Zhang Zhang stepped forward and clapped his hands, "Come, the black dragon listens to my command and lies down!" ”

The black dragon immediately fell to the ground.

Zhang Li laughed excitedly: "Okay, great, from now on we will be brothers." ”

Han Li took out the leg bone of Case No. 2 from her bag and gave it to the black dragon to sniff, and the black dragon immediately lowered his head and searched.

Canine's sense of smell is dozens of times that of humans, and professionally trained drug detection dogs can easily find drugs hidden in car tires, and the work efficiency of search and rescue dogs and explosive disposal dogs is much higher than that of humans. The black dragon has lived with Qian Fugui since he was a child, and the tacit understanding between a person and a dog is extremely high, and Qian Fugui knows all about any action of the black dragon.

The black dragon lowered his head and walked straight to the construction site, after drilling through the fence, he came to a pit where dirt was piled up, this place was originally a stinky pond, according to the plan, this place will be filled in and transformed into a small square, a large amount of loess has almost filled the pit, and several mud trucks are dumping construction waste.

A pile of mud and sand several meters high in the mixing plant attracted everyone's attention, these mud sofas were black and smelly, and there were a large number of water stains on the ground, which looked like they had just been pulled back. Without any treatment, the sand is poured into a blender.

Seeing this, several security guards surrounded and tried to stop the investigation, but when they found out that it was the police who were handling the case, they immediately called their manager over.

The manager was a mustachioed local with a rather tough attitude, repeatedly saying that they had nothing to check here.

Professor Lei leaned down and grabbed a handful of mud and sand and squeezed it in the palm of his hand, and suddenly water stains flowed out of his fingers, and the remains of some aquatic creatures appeared in front of everyone's eyes.

Qian Fugui also grabbed a handful and sniffed it, and said, "That's right, it's this kind of mud and sand, and I'm too familiar with this smell." ”

"What the hell are you going to do? As I said, we all have procedures and permits here, including the sand. The manager said impatiently.

"Really?" Professor Lei glared at the manager and said: "We have clear standards for construction sand, and we must not completely use river sand instead of prefabricated sand. It's just mud and sand, it's not up to standard at all, if I notify the relevant departments of this matter, do you know what the consequences are? ”

The manager's face changed when he heard this, he knew that he had met an expert this time, so he quickly changed his words.

"Don't talk nonsense, our sand is not used for the main building, it is only used temporarily, such as making a trench or something, what are you going to investigate?" The manager's attitude was much better, and his little eyes kept blinking for fear that Professor Lei would be more serious.

In fact, this kind of sediment cannot be used at all, which is obviously shoddy and cutting corners.

The black dragon finally stopped, roaring and digging at the dirt with its feet.

"Found it!" Qian Fugui said loudly.

Wen Yuming stared at the manager and asked sharply, "What is buried here?" ”

"How do I know, we are all qualified here, and there will never be anything you want." The manager said with an unhappy look on his face.

"Dig!"

Wen Yuming ordered the police to dig immediately, and less than two meters down, a skull appeared in front of everyone.

The manager was dumbfounded and stammered, and he explained that all the dirt was pulled by the driver of the construction site, and he really didn't know anything else.

"Director Wen, leaders, I really don't know about this matter." The manager, who had been arrogant just now, turned white with fright, sweat on his forehead, and repeatedly said that he really didn't know.

"You can find a reason to find all the drivers, and if you can't find it, I'll count you on it." Wen Yuming said.

"Okay, I'll get you all there!"

The manager turned and ran, at a fast pace.

The police cordoned off the scene, and Han Li put on gloves and immediately went to work.

The drivers of the tutu were all called over, and stood outside the blockade, and the skulls were placed on the white cloth not far from them, and one by one they lowered their heads and whispered.

Zhang Li turned his head sideways and whispered to Tang Tao, "There are more than 30 drivers here, is the person we are looking for really here?" ”

Tang Tao didn't answer, but stepped forward and said loudly, "Which of you has pulled sand by the river?" He stood behind me without pulling the sand. ”

The drivers acted quickly, and a third of the drivers stood behind Tang Tao.

"We found a skull in the sand, who pulled it?"

Everyone discussed it again, shaking their heads one by one.

There is no surveillance at the scene, and everyone present may be a suspect, but how can the suspect be found in a short period of time? Sophie held her chin and looked at the crowd in front of her.

"I think I already know who the killer is." Tang Tao slowly raised his hand and pointed at the crowd.

The drivers had different expressions and turned their heads sideways to avoid it.

"That's you!"

Tang Tao suddenly pointed to the small driver and said loudly.

The audience was amazed.

All eyes were on the little driver.

"Wan Defu, it's really you!" The manager snarled as he pointed at the little man.
