didn't have time to say anything, Qiu Lan walked side by side with her colleagues from the Serious Crime Team and the Forensic Department behind her into the dilapidated courtyard that had been taken over by the police.

On the side of the house there was a small vegetable patch, next to which was a manure pit with red, white and blue plastic bags, surrounded by a few bricks, and the mud had dried up.

A foul stench came from the cesspool, polluting the air.

"This manure tank seems to be many years old, and it hasn't been cleaned yet, and the biogas is very heavy, so let's take a mask and bring it. Qiu Lan held her breath and opened the box in her hand and passed the disposable medical mask to her colleagues in the Serious Crime Team and the Forensic Section.

After putting on their masks, everyone approached the manure tank and looked around carefully, looking for possible places where the bones might be buried.

But after decades of wind and rain, there is no trace of it at all.

"Boss, do you think Zeng Qipeng will throw the bones directly into the manure tank?" Xiao Tiao, who was standing on the edge of the manure tank, frowned, wiped the sweat from his forehead, and spoke with difficulty, his heart tumbling with a disgusting taste.

Hearing his speculation, Xu Chengyan's eyes sank, and his heart was furious.

This manure tank is closed, and the excrement in it can only be removed manually, but this manure tank has been abandoned for so many decades and no one has taken care of it, and the contents do not know what they have become corrupted.

If the bones were really thrown into this cesspool, then they would have to be put on the same head.

"Officer Xu, I think the biggest possibility now is the inside of this manure tank. Cao Fan shrugged helplessly and glanced around, "We've probably seen it all here, and there is basically no problem under the soil layer." ”

"And the rest around the manure tank we've already looked for, only. Expert Cao's heart tightened suddenly, and his stomach turned upside down.

Hearing his words, Pei Pei twisted his facial features in pain, with a look of disbelief, "No, are we going down to the manure tank to salvage the bones?"

"It's not about going down into the manure tank to get the bones, it's about getting everything in the manure tank up. Mo Heng, who was carrying the silver box, walked out, and his flat expression did not fluctuate at all.

She is the only forensic officer in the Forensic Identification Section, who is highly professional and unsmiling.

"After so many years, there are only bone frames left in this place rich in microorganisms and bacteria, and there are more than 200 bones in the human body, and we have to find them all one by one. Mo Heng looked at the people around him calmly, without a little uncomfortable expression on his face.

After all, in her eyes, this is work, as long as it is related to work, whether it is up the knife mountain or the sea of fire, it is incumbent on her and there is no hesitation.

"Yes, Mo Heng is right. Qiu Lan carried the box and walked over from the other side of the wall, her brows slightly furrowed, "But this time we are lucky, there is no need to be so troublesome." ”

Hearing her words, everyone moved their eyes to her.

"Doctor Qiu, is what you said true?" Pei Pei looked at her excitedly, his eyes full of joy.

"Hmm. Qiu Lan nodded lightly, and fixed her gaze on the cement wall that separated the manure pond vegetable patch and the house, "Look at this wall, although this wall has a sense of age, but it can still be seen from the room over there, right?"

"This concrete wall was not built with the house, but was added later. She walked to the end near the manure tank, crouched down by the wall, and pinched up some of the dirt in the small distance between the wall and the manure tank with her gloves on.

"Just now, when you were all searching here, I found this soil on the other side of the wall, and this soil is different from the others. Qiu Lanjiang gently patted the soil off his hand, slowly got up, and said indifferently, "This soil is more acidic than ordinary soil. ”

"The biggest possibility is that there are bones buried in the soil under the concrete wall. She lowered her eyes, and the expression on her face became a little more serious, "When the fat layer of the human body is broken down, it forms a fatty acid, which is phenyl hydroxycesin anesate. ”

"This substance changes the properties of the soil, and the acidity can be maintained for up to 50 years. ”

After speaking, Qiu Lan took a few steps back, pointed to the place where the cement wall and the manure tank were separated, and said in a gentle tone: "Officer Xu, I think we need a hammer to chisel this place open." ”

Ten minutes later, the police officer of the Crime Squad Zhigao summoned a villager in the village to dig a large hole in the cement wall with a hammer, revealing that Qiu Lan had noticed something unusual.

"Thank you all for your help, and we'll take care of the rest. Qiu Lan took off her mask and thanked the villagers for their enthusiasm for helping with a light smile.

It is very likely that the bones will be buried in this fast ground, and the exhumation of the bones must be carried out with great care, as the evidence may be destroyed if you are not careful.

Qiu Lan walked to the scaffolding in the small courtyard, picked up a shovel, and prepared to dig up the bones, but was stopped by Xu Chengyan, "Doctor Qiu, I'll come, the injury on your neck is not healed yet, let's do the heavy work." ”

"Yes, Doctor Qiu, you are the second female workaholic I have ever met, and the first one is Mo Heng. Cao Fan smiled softly, handed the box in his hand to the colleague behind him, and picked up the shovel by the wall, "I'll come with Officer Xu, don't worry, I know how not to destroy the bones." ”

"Then I'm sorry for you. Qiu Lan tilted her head, raised her eyebrows, and handed the shovel in her hand to Xu Chengyan.

After shoveling through the soil layer about 30 centimeters, a gray-white hand bone appeared in everyone's eyes.

"The bones are buried here. Qiu Lan looked at the bones and sank her eyes.

After shoveling away the top layer of soil, Cao Fan picked up a small loosening shovel, took the bones out of the soil along the perimeter of the bones, and placed them on the clean nylon cloth next to them, while Qiu Lan took a small soft brush to clean the bones.

"Chief, how did you find out that there is still a skeleton here?" Pei Pei raised his eyebrows, his voice filled with a hint of doubt and admiration.

This is all thanks to Dr. Qiu, she thought of using the method of memory echo to evoke Zeng Qipeng's memory, and suspected that there were still bones in the manure tank next to the vegetable field here, which should be Zhang Yunmei's. Xu Chengyan told the other police officers of the Serious Crime Unit and colleagues in the forensic department about the clues she and Qiu Lan had obtained at the hospital.

"I haven't heard of the memory echo, but Dr. Qiu is really amazing. Pei Pei raised the corners of his mouth, smiled softly, and glanced at Xu Chengyan with deep meaning.

Officer Xu was careful about Dr. Qiu, she knew.

The process of excavating the bones probably took more than two hours, a total of two hundred and seven bones.

Two hundred and seven?

The bones of adults are not like those of children, all the bones have been completely combined, only two hundred and six, so where did this extra piece come from?

Qiu Lan, who was full of doubts, was not at ease, and counted it again with her assistant Xiao Cong, and it was still two hundred and seven yuan.

"Officer Xu, this time, I should be able to answer a lot of questions for you. Qiu Lan put down the things in her hand, got up slowly, and looked at the person in front of her, her voice calm.
