After the secret passage was discovered, Cao Zhen immediately made a decision and asked the police station to send an appraisal officer to come over and do a comprehensive inspection of the secret room in the secret passage, even if no one has used it for a long time, as long as someone has lived in it, some cell tissues will remain, and if you are lucky, you may be able to match the DNA of human specimens.

The appraisal personnel were led by Lu Xinqing, and a full eight people came, and they also brought large electrical equipment for lighting in the dark tunnel.

It took 35 minutes for Ma Yuanzhong to pinch the stopwatch and walk back and forth, which was twice as long as the Du family who walked the mountain road to Huangjiatang outside.

This led to a conclusion that the transportation of 'goods' from this dark channel to the Du family is already a sure thing.

The main hall of the Du family was temporarily used as a temporary meeting room by the police, and Cao Zhen brought a list of the engineering team responsible for repairing the ancient tomb that year.

These lists are kept in the city government, and it is not difficult to obtain them, just a phone call and someone will send them.

"After the ancient tomb was discovered, the city government decided to repair the ancient tomb, and there was also a grant on it, but the amount was not very large, Y city was biased, and its own engineering team was not able to take such a big job, so the Y city government found an engineering team from other cities to come and help, I took a look, there were about seven or eight, according to the records of the year, because the allocation was not very sufficient, and more than half of the money had to be brought by Y City itself."

It's not the Ming Tombs in Beijing, a small city, like repairing ancient tombs and turning them into attractions, you must come by yourself.

Jing Sa said: "This kind of repair project has a lot of oil and water, and it must be greasy." ”

There are many types of construction project expenditures, more than a dozen projects are down, and no one will pay attention to them if they are not careful.

Needless to say, this is the case in society, just like clothes, they are all huge profits.

As for the engineering team, it is more complicated, the general engineering team has its own contractor, most of these contractors are attached to the engineering company, there are a wide range of interpersonal relationships and labor resources, especially skilled workers, as long as they can get the job, they will do it, the engineering team usually takes the job will be the profits and then transferred to the contractor, or help the contractor introduce the work, and then take a cut.

The engineering team is generally a white wolf with empty gloves, so it is not a good master, especially municipal engineering, which cannot be explained clearly in one or two sentences.

Because if you find a professional construction company to do it, you have to take out 200,000 performance bonds before starting construction, and after paying the deposit, you have to bid for it.

Therefore, the contractor has a place to get a job, many engineering teams are internal contracting system, by the boss himself to make decisions, not only save time and effort, but also earn more, as long as the quality of the construction is passed, the government's own engineering team will also invest in a tower crane, temporary facilities, mixers, steel machinery or something in the early stage, you can retire, other work is the following contractor to do, building a building is so simple, not to mention repairing the ancient tomb.

Everyone has a meal, the interests are clear, and the work can begin.

This kind of contracting system, if it is done, it is fine, if there is a tofu slag project, then it will be difficult to investigate, because the person in charge cannot be found, everyone can push it around, and when it is really checked, it is no longer known that it is the year of the monkey.

Moreover, the contractor is a temporary worker, some are directly found on the road, they don't know each other, they will give money when they are done, and then recruit people again when there is a new job, if a project needs more than 50 people, these 50 people may not all know, who knows which contractor or small company you are, they are all out to mix and eat, and if you have money, you can do it, anyway, they are all working together, and they will not ask their ancestors for eight generations.

This also made a loophole in the construction of the Du family's secret room, and when the construction waste was removed, as long as the words of the ancient tomb repair were posted on the cart, who could tell whether it was right or not.

She knows the doorway, but it has nothing to do with the case, "Whether there is oil and water or not, it has nothing to do with us." ”

"So what are you going to look for?" I specially asked him to find so much information.

"You just said, the appropriation above is not large, looking at the current municipal economy of Y City, it is estimated that a few decades ago it was barely enough to make ends meet, in this case, the government has no money, but it wants to repair the ancient tomb, what will it do?"

Cao Zhen immediately answered, "Find investors!" ”

This method is the same as filming a TV series, first find investors to invest money, and after the TV series is filmed, when it is played, the subtitles will be marked with which company invested, which is a disguised advertisement.

The same can be true of the ancient tomb, after the repair, hang a signboard at the door, which will list those companies that have invested, so many people who come to travel, one out of ten people can take a look, and the purpose of publicity will be achieved.

Unfortunately, after the ancient tomb was repaired, within a few years, it was depressed, which is probably something that many investment companies have not thought of.

She nodded, "I guess the Du family's hospital must be one of the investors in repairing the ancient tomb." ”

"Huh?"

"If you have an investment, if you want to secretly send someone over to build a secret room and a secret passage, it will be more effective with half the effort, isn't it?"

Cao Zhen and Jing Sa immediately opened their mouths, yes, there is nothing suspicious at all.

But......

"Wai, the name of Dujia Hospital is not written on that signboard!"

"If you don't write, can't you invest? Maybe people deliberately don't want to go up there? ”

After listening to the analysis, the police immediately checked the details of all the investment companies.

Sure enough, the name of the hospital run by the Du family in S City was discovered, and the name on the investment confirmation letter was still Du Yijian.

Jing Sa immediately cheered and encouraged, "It's really there!" ”

Cao Zhen was also very happy, and couldn't help but burst into a foul mouth, "This is fucking evidence." ”

Obviously invested, but did not register the name on the signboard, which is clearly a lack of heart.

The investment confirmation letter was signed by Du Yijian himself, which shows that he is very aware of this matter, and he must be before the renovation of the ancient tomb project begins

Before the start of the tomb project, he will definitely come to Y to learn about the specific plan of the investment project.

He has been to Y City, and it is so close to Huangjiatang.

To say that he doesn't know that Du Yichen is in Huangjiatang, let him lie to the ghosts.

Although the direction is not very large, he can also use himself just to discuss investment matters, stay here for a few days, whether his brother is here, he doesn't know if he is not clear to prevaricate, or this is a good thing, there is no need to make everyone know, but the Du family in Huangjiatang has such a strict case, and the construction of the secret room and the secret passage and the repair of the ancient tomb are carried out at the same time, even if there is really no contact, in this case, he will not escape the involvement.

"I'll call back to the Deng Bureau immediately, and this time I will say that I will also get the search warrant down."

Jing Sa was still dancing in place with excitement, her eyes glanced at Wanwan, forgot about her pregnancy, and directly slapped her on the back with her hand, "You, it's really yours, you can think of it." ”

She staggered forward by her pat, and Cao Zhen was so shocked that she almost chopped off her hand.

He is a person who has had children, although he is not a woman, but the elders of the family have said that pregnant people cannot be slapped on the back, they will have a miscarriage.

It's just a statement, but many believe it.

He asked with a white face, "Duanmu, are you okay?" ”

The investigation of the case is the investigation of the case, and this person's life may be on the line.

She was just frightened, and she didn't feel any discomfort, and shook her head, "It's okay!" ”

Jing Sa realized what he had done, and hurriedly apologized to Wanwan, "I didn't mean it, I really didn't mean it." ”

"It's okay, it's okay, don't be nervous."

"If you have something, you must say it." She really has the urge to chop off her hands now, in case something happens to Yingwan, not to mention that she will blame herself, Kangxi has to slaughter her whole family.

Cao Zhen pulled Jing Sa aside, and scolded him, "I said what are you excited about, the case hasn't been solved yet, you give me a snack." ”

"Oh!" Jing Sa knew that he was guilty, hung his head, and let him curse for three minutes.

Ma Yuanzhong is an unenlightened person, seeing that they have clues in the investigation of the case, he should be in a good mood, and he asked, "Senior brother and sister, can I move that cabinet home?" ”

Everyone glared at him.

Why is this kid so lacking in heart?

The policemen who were guarding the door with him had already pretended that they didn't know him.

"What to move!" Cao Zhen shouted, "What are you always thinking about the cabinet? ”

Ma Yuanzhong said, "Next week is my mother's birthday, she won't be happy if I send anything, send this broken cabinet, she will be able to wake up with a smile in her dreams." ”

Their family runs a garbage recycling station, which is just a hobby.

"Here you go, here you go, when the case is solved, you will take it home."

"Thank you, brother!" He took a yellow label and immediately pasted it on the cabinet, "Brother, I signed it, don't rob any of you from me." ”

Who will rob him, this cabinet is a thing at the scene of the crime, it is not good to say, it is evil.

That's what this brainless kid would want.

Jing Sa was scolded and didn't dare to speak anymore, so he muttered in the corner, "Fortunately, this kid was not assigned to our bureau, otherwise he would definitely be angry." ”

Thinking of Deng Keyou's expression of blowing his beard and glaring, she grinned and laughed out loud.

"Senior sister, what are you laughing at?"

"No, no, nothing?" This can only be understood, not spoken.

Ma Yuanzhong saw that she was always staring at herself, and her heart was a little blocked, "You people in big cities are weird." ”

Jing Sa choked and said: "It has nothing to do with whether you are from a big city or not, you don't wear hats indiscriminately." ”

"Cut, you must think I'm stupid."

"Why, I think you're pretty ...... Pretty real. Jing Sa's subtext is, yes, I really think you're stupid.

Hearing this, all the criminal police officers laughed.

At this time, Fang Qiao came.

"Brothers, let me go, I'll find Duanmu Wanwan."

As soon as she heard her name, she raised her head, "Look for me!" ”

As soon as Fang Qiao saw him, he immediately rushed over, "Duanmu, Duanmu......" He gasped sharply, "I have a heavy discovery." ”

"What?"

Jing Sa and Cao Zhen also leaned their ears together.

"Those human specimens all have the same blood type, and there are ......" is probably running in a hurry, and he is still panting there.

Jing Sa hurriedly said, "Fang Qiao, can you finish the words at one time." ”

"You let me take a break, I'm not a criminal policeman, I'm a forensic doctor, and I don't usually practice."

The body is naturally inferior to those of them who are criminal policemen.

"Drink saliva, drink saliva." Cao Zhen handed him a bottle of mineral water.

He took a hard sip and let out a long breath, "Look at this and you'll understand." He threw the information in his hand to her.

The data lists the DNA, blood type, and...... of the human specimens HLA value.

HLA, the Chinese name is transplant antigen.

In order to reduce the rejection of transplant organs, human leukocyte antigen (HLA) is a histogenetic code on human chromosome 6 and is a numerical value that reflects the histocompatibility between the recipient and the donor who provided the transplant and the rejection of the transplant.

In other words, transplanted organs should not only look at the blood type, but also the HLA must be similar or the same before transplantation, otherwise even if a healthy organ is transplanted, the recipient of the organ will suffer from complications due to too much rejection, and the postoperative organ will fail or die.

On the information that Fang Qiao gave her, this is the value.

The HLA values of those in the human specimen are all the same, which means that their organs can be shared or used in one person.

Who is this person?

The answer is clear.

Du Yanfang.

There was no second person but her.

------Off topic------

I hung up five packs of salt water today, and I still pulled it, and I still had a fever, and the second dog completely became a plague dog......

Solving.

Can you not pull?

Even if you have to pull, can you not have a stomachache, it hurts, like a labor pain, a burst, the intestines are pulled and knotted.

Dead hearts are all there.
