Siheyuan: I have a system and I smile with satisfaction

Expert Hao found Ni Daguo and asked him to analyze a soil layer with him.

"Master, these layers of soil look a little strange to me. The colors don't seem right."

Ni Daguo took the soil, looked at it, and then smelled it. "What is this? It must be soil where a dead person was buried. And there is a bit of blood in it. That person must be bleeding, but the amount is not large."

Expert Hao sniffed carefully and said, "I can't smell anything."

Ni Daguo was stunned for a moment, then guessed that this was because his nose was unusually sensitive and because his mental power had become strong.

"Go find someone to do a test to see if there is any human blood in the soil. If I'm not mistaken, this person was killed and really died. He was taken away before he could rot."

Expert Hao couldn't believe it.

Ni Daguo said: "Go get tested quickly."

Ni Daguo also told Zhao Qianqian about the DNA technology, and then it was developed. Otherwise, paternity testing would not be possible.

And Ni Daguo's senses are so sensitive that he can sense the aura of death.

That's why he made this conclusion.

Expert Hao hurriedly asked someone to do an appraisal.

The results showed that it really contained human blood.

This... must be a murder case.

The public security department will immediately start an investigation to see if there is anyone who matches the DNA. They can start the investigation from nearby areas, mainly to see if they can find the relatives.

Anyone who reports a missing person must undergo a DNA comparison.

Sure enough, after matching, the missing person was found to be Zhao Da, who had been missing for more than ten days and had not returned.

The case was reported but the person was never found. No one was found alive or dead.

Based on the clues, the police began to gradually investigate Zhao Da's social contacts, who he contacted and what he did.

It was discovered that Zhao Da was addicted to gambling and often went to the village to play cards and money with others.

At the beginning, they played small, one or two cents, and later on they played bigger and bigger, and started playing with ten or twenty dollars. The one who lost the most would lose a hundred dollars in one night.

One hundred yuan is several months' income for ordinary people. How can they afford it?

During this period, Zhao Da was very lucky and made money for three consecutive months.

I can earn dozens of dollars every night.

After three months, I made several thousand yuan.

This caused many people to be envious and jealous, and some even began to hate him.

Before this, a few card players lost their bets and started fighting with Zhao Da with red eyes.

After investigating together, the suspect was identified based on the time of Zhao Da's disappearance and the possible time of death.

The suspect was then taken away for questioning, and in the end, faced with the evidence, the suspect could only confess to the murder.

The suspect Zhao Xiaosi lost a lot of money in gambling and had a fight with Zhao Da.

The main reason was that Zhao Da won a lot of money from him, and Zhao Da had a bad gambling character. He would often start boasting about how he won after winning, and they were left with nothing even from their underwear.

He also often cursed at them, which made Zhao Xiaosi very dissatisfied.

Because he lost all his money in gambling, his family was destitute and his wife even ran away in anger.

Even in this state, he was still provoked by Zhao Da's words and couldn't help but trick Zhao Da into the wilderness and then beat him up with a club.

It just so happened that Zhao Da was beaten to death in one blow. Zhao Xiaosi was frightened at the time. He didn't want to beat Zhao Da to death, he just wanted to teach him a lesson. Unexpectedly, he killed him with just one blow.

There was a little blood on the back of Zhao Da's head, but not much. Zhao Xiaosi ran away in panic.

But in the next few days, no one noticed that Zhao Da was dead, and Zhao Da's family thought that Zhao Da had gone somewhere else to gamble.

This kind of situation has happened before. Once the gambling addiction comes back, it is common for him to not come back for several days.

However, ten days passed before he returned, and his family members felt something was wrong. They went to the common places where he was seen, but did not see him, so they reported him to the police.

After the family reported the case, Zhao Xiaosi felt guilty, so he ran to the wilderness and found Zhao Da's body still there. Then he found a place to bury Zhao Da.

It just so happened that when Expert Hao and his team went there to do a geological survey, Expert Hao always felt that the soil was a little different.

Then I brought it back and wanted to share it with Ni Daguo, but I didn't expect Ni Daguo to see the difference right away and even tell me the reason why.

After the investigation, they actually solved a murder case.

Expert Hao was full of admiration for Ni Daguo, "Master, you are so amazing. I really admire you."

Ni Daguo, "Get lost now. I can't bear to see you like this."

"No, Master is so powerful, please teach me how to do it."

Ni Daguo was too lazy to pay attention to him and threw him a book on solving crimes, which contained many detailed analyses of the cases.

Including the study of soil.

Expert Hao was actually fascinated by it.

Ni Daguo threw a few books to him again, including both domestic and foreign ones.

These books are very common in Hongkong, but they are rare in the domestic market.

Expert Hao became even more fascinated now, and studied these cases every day, especially the analysis of the soil and geographical environment in the cases.

"You have to remember that you are an archaeology expert, not a crime-solving expert!"

Seeing that Expert Hao had forgotten to eat and sleep, Ni Daguo kindly reminded him. The expert waved his hand and said, "Oh, whether you are an archaeologist or a crime-solving expert, you have to understand the soil stratum clearly."

"If you want to find out, go back to your own home and find out. Don't stay here. This is not a shelter. Go back quickly. Here are a few books. Take them all."

Ni Daguo finally managed to drive Expert Hao away, but it was already very late.

But someone came to disturb his rest so late. Director Pan came uninvited and said, "Daguo, you have done a great job, but there is still a case that needs you to investigate with me. I think you are really good at solving cases. Well, you can solve the case while you cook."

Ni Daguo laughed, "So I'm doing two jobs at work, so should I get two salaries?"

Director Pan said with a smile that we should serve the people, so why should we care about so many things?

Ni Daguo had no choice but to cheer up and follow Director Pan to solve a very urgent case.

The owner of the room died in the room, but there were no special traces. The main reason was that this person was the leader of a government department.

They tended to believe that he was murdered, but there were no signs of murder. However, this suicide was too bizarre because the wound was on his back, and such a wound could not have been caused by him.

Some public security officers even wondered if it was done by enemy spies.

Director Pan thought of Ni Daguo and told people not to rush to move the body, but to invite Ni Daguo to come and help solve the case.
