Long Zihan asked, "What's so special about the composition of the soil?"

Wang Xiaoguang replied: "Collapsible loess." ”

"Collapsible loess?"

The Chuyi people explained: "Collapsible loess is a special soil, mainly loess. Under the combined action of the self-weight stress of the overlying soil layer or the self-weight stress and the additional stress, after encountering water, the structure of the soil is damaged and the volume shrinks is called collapsible soil. ”

Long Zihan asked, "There isn't much soil like Shanghai Tang, right?"

"This ......" Chu Yiren hesitated for a moment and said, "Let's let a geologist or relevant department investigate this." Because there are places that we know that have already done the work. ”

Long Zihan nodded and instructed Liu Yuanheng: "You go to contact, and after you find the location, send someone to collect soil so that you can confirm the specific location." ”

Liu Yuanheng nodded and replied, "Yes." ”

After this topic ended, Mo Bei frowned and said: "The murderer died at the door, and there are no fingerprints and traces of the suspect in the house, indicating that he did not enter the deceased's home." ”

"The murderer's purpose is very clear, that is, to come to the deceased, and turn around and leave after killing people simply and rudely, without letting the deceased die miserably, and leaving no more traces. It shows that the murderer was prepared for a long time, and his psychological quality was very good, and he was very calm in the process of committing the murder. ”

Erin's voice fell, looked at Long Zihan, who hadn't spoken for a long time, and asked, "What are you thinking?" ”

At this moment, Long Zihan frowned, looking like he was out of the world.

Long Zihan said: "I'm thinking, although the deceased Liang Youqi didn't provoke anyone at home, but on the way out to buy things, he met someone or something, and the neighbors couldn't tell at all, right?"

Zhao Xiaohu asked with some surprise: "Long Shao, do you want us to find out where he has been going out recently? How can you check this? Who knows where he has gone?"

Long Zihan said: "The deceased Liang Youqi's family has a lot of New Year's goods, and he is just an ordinary farmer, and he must go to a cheap place to buy New Year's goods. And in that area, as far as I know, there was a market just before the Chinese New Year. ”

Zhao Xiaohu suddenly realized: "The New Year's goods in front of our family are the ones that my mother went to the market to do." Not to mention farmers, most people like to buy things on the market, trying to get cheap. ”

Erin nodded, thought about it and said, "The people who come to the market to sell goods almost all go from one place to another place to catch the market. Find out where they went after setting up the market near the deceased's house. See if you can find them. ”

Long Zihan added: "Check the source of foie gras, goose meat is not cheap, and there are not many shops that sell foie gras alone, go and check! In addition, arrange for someone to check near the deceased's house to see if there are some small shops or stalls nearby, and maybe there will be some clues." Also, try to find the grandson of the deceased. ”

Everyone responded in unison: "Yes......"

Because it was still the New Year, many shops were in charge of the doors, and the people who went to the cave to rush to sell goods had not yet come out, and the investigation of the case encountered great obstacles.

However, although the source of foie gras has stalled, the police have been able to contact one or two vendor owners.

After learning the location and time of the next gathering, the case could only drag on for a while.

People can only hope that time will pass quickly and the case will be solved sooner.

Fortunately, the news of collapsible loess came back, and they now have a geographical location with collapsible loess.

Long Zihan instructed: "Send people to collect collapsible loess from various places and come back for analysis. ”

"Yes......"

On the morning of the second day of junior high school, Long Zihan was woken up by two little demon kings.

Long Chuchu made a fuss: "Dad, Dad, get up and have breakfast." ”

But Long Yifei said realistically: "After breakfast, I hurried to my grandparents to pay New Year's greetings, there are red envelopes." Dad, for the sake of our New Year's money, you move faster. ”

Helpless, Long Zihan hurriedly got up, washed up, and went downstairs.

When I came to the living room and looked in the direction of the dining room, Chu Yiren was helping Sister Du make breakfast together.

Once, at breakfast time, he could see his mother's busy back as long as he stood here. Today, that place has been taken by his wife.

When I think of my departed mother, I still feel heartache, guilt, regret, and regret. He always said that he should accompany his mother well, but until she left, this sentence did not come true.

He always felt that there was still a lot of time, but time was fleeting. really responded to the sentence "the son wants to raise but does not wait".

Perhaps, everyone grows and matures through gain and loss, until they grow old.

What he can do now is to spend more time with his family so that he doesn't regret it in the future.

"Hey, brother, why are you looking at your sister-in-law's back here?

Yan Hao's ridicule came from behind him, and Long Zihan said angrily: "I heard that your former classmate has become a father......

"Yes, I'm afraid of you, don't mention this, I have a headache. ”

At this time, Long Baichuan's voice sounded: "If you two don't come down to wash your hands and eat, what are you talking about on the stairs?"

"Dad, I'm talking to Yan Hao about the big thing of him starting a family and starting a business. ”

Long Baichuan nodded and said, "Xiao Hao graduated this summer, and he is not young, after finding a job, he is almost ready for marriage, right?"

"Hehe, Dad, have you forgotten? He has one less girlfriend......"

After breakfast, Chu Yiren asked, "Dad, why don't you come with us?" ”

Long Baichuan shook his head and said: "I promised the uncle yesterday, go to him today, and I will take Yan Hao's kid to your uncle's house in a while, you don't have to worry." In the evening, you will also come over to have a meal together, and the girl in Yaqiu in the province will be noisy. ”

"Alright then, we'll see you in the evening. Dad, let's go. ”

After speaking, Long Zihan went out with his wife and children.

When I left the house, I was just about to get into the car when I heard my daughter calling through the window: "Teacher Qin." ”

On the opposite road, a mild-mannered man waved at Long Chuchu in the car.

He walked over in a few steps and greeted with a smile: "Chu Chu and Yifei have a good New Year!"

The two children said in unison, "Happy New Year, Teacher Qin!"

The man looks like he is twenty-six or seventeen years old, he looks white and clean, and he has a good temperament, so it's no wonder that these two children like him.

Long Zihan greeted this Teacher Qin and said, "Hello, I'm Long Zihan, this is my wife." ”

Chu Yiren nodded to Teacher Qin and said, "Happy New Year." ”

"Happy New Year, Happy New Year, my name is Qin Nian, I just moved here, it's a pleasure to meet you. ”
