Lu Fei smiled, "Master, since those five corpses can speak, wouldn't it be easy to find out the cause of their deaths?"

The old man shook his head vigorously, "No! What you said is wrong, even if the five of them can speak, they still can't find out the truth, because they don't know how they died."

Luffy frowned, "That's weird. Five corpses can talk, and they don't know the cause of their death. This has really become a world wonder."

The old man sighed, "Yes, because they don't know the cause of death, all five of them are depressed and want to know how they died. In fact, according to my estimation, the murderer should be a serial killer, and this murderer should be unjustified. Occupation, living in the countryside, owning a big truck, and when I'm fine, I often drive around on the road to find a target."

Lu Fei immediately shook his head, "Master, you are not right. Forensic doctor He and I have also analyzed the causes of the death of these five corpses for a long time. We concluded that the murderer was an uncle who was born by a special soldier and sold mutton skewers. "

The old man was completely stunned. "Ah? Is the murderer a vendor selling lamb skewers? How did you come to this conclusion?"

Lu Fei smiled and said, "Old man, do you remember the iron drill stuck in the head of the female corpse?"

The old man nodded, "Of course I remember. What's wrong with the iron drill?"

Luffy said, "In the corridor just now, Forensic Doctor He has carefully checked the iron drill, and Forensic Doctor He has checked the mutton oil from the iron drill. This is enough to show that the iron drill was used before. Skewers of lamb."

The old man frowned, "Well, there is nothing wrong with your reasoning. But I still can't figure it out. Why do you believe that the murderer is the uncle who sells skewers because the iron drill on the female corpse's head is a mutton drill? "

Luffy smiled, "Generally speaking, the murderer will choose the tool he has the most in hand to kill. For the uncle who sells meat skewers, it is only natural to grab a drill and stab into the victim's head. But for others, few would have thought that iron drills could also be a murder weapon."

The old man smiled bitterly, "Well, your analysis makes sense. However, what I am curious about is, why does an uncle who sells skewers kill their family of three?"

Hearing this, Lu Fei and He Chuyao were all excited.

Lu Fei smiled and said, "He Forensic, it seems that our analysis is not wrong. Those three tower-like people are a family of three."

The old man was puzzled, "They were originally a family of three, why are you so excited?"

He Chuyao smiled and said, "By the way, old man, you talked to them, what is the relationship between these five people?"

The old man smiled, "The relationship between these five people is very complicated, and the five of them have complicated entanglements with each other."

Lu Fei and He Chuyao opened their mouths in surprise.

He Chuyao said, "Ah? Did the five of them know each other?"

The old man smiled and said, "Of course knowing, not just knowing, but also having deep grievances."

Luffy said, "Ah? The grievance is very deep, it seems that it is a vendetta, what forensic medicine, my reasoning is not, it is a vendetta."

He Chuyao smiled, "Student Lu Fei, don't get excited, what the old man said is that the conflicts between the five people are deep, not that the murderer and the five people are deeply grudges."

The old man smiled and said, "Yes, the five of them have deep contradictions in themselves. It was originally a family contradiction, but in the end it got worse and worse, leading to a tragedy."

Luffy said in surprise, "Master, what are you talking about? Family conflict? Is it possible that these five people are a family?"

The old man smiled and said, "I'd better talk about the relationship between the five people first. The three stout guys are big men and a family of three. Do you know that?"

Luffy nodded, "This is naturally clear. These three tower-like guys are a family at first glance. They are all thick and thick. But what I can't figure out is that the beautiful girl actually belongs to them. Human? Regarding age, a girl can indeed be the daughter of that couple, but I cannot believe that such an ugly girl will give birth to such a beautiful daughter?"

The old man smiled, "That ugly girl is indeed not the girl's mother. That girl is just the adopted daughter of the couple."

Luffy nodded, "Oh, I understand. But what is the relationship between that handsome guy and them? Is the relationship between handsome guy and girl friends?"

The old man shook his head, "No. That handsome guy is a lawyer. He was only hired by a girl to fight the lawsuit. He may have admiration for girls, but they are not lovers."

He Chuyao frowned, "Lawyer? In a lawsuit? Old man, I'm confused now, the more I listen, the more confused I get."

The old man smiled and said, "I'll explain to you. The girl is the adopted daughter of the couple. The girl lost her parents since she was a child. She was still young and still in her infant. The couple may be out of good intentions, or they may have come out. In greed of the comfortable living conditions in the city, they adopted this helpless little girl. As adopters, they lived in the little girl’s house grandiosely. Of course, they declared that they were the little girl’s aunts and uncles. Because the little girl’s parents have no relatives, no one investigates the authenticity of their identities. As time goes by, the little girl grows up, she knows a lot, and she knows that she has several properties under her name. The houses are all located in the downtown area and are the assets left to her by her parents. However, these houses are all rented out now, but the rent is held by the uncle and aunt. They can't get a penny, so naturally they start to feel dissatisfied. In addition, my uncle gambling, my cousin didn’t learn well, often ran out and fooled around and didn’t do business. My aunt stayed at home and didn’t go to work. The uncle’s family of three spent all the rent on her house, which should have belonged to her . You know, the monthly rent for a few houses in the downtown area is also a considerable income. Because the rent is occupied by the young girl, and the three members of this family are all idle, they become more and more disgusted with them, of course, Maybe it was because of her friend's instigation that she turned her face and decided to drive them out of her home. So she started to make a big fuss, even hired a lawyer, took them to court, and demanded that the family of three leave their house. The family of three panicked immediately. They have been living in the city for 20 years. They have become accustomed to the cleanliness and comfort of the city. They must not be used to going back to the countryside all at once. Because it was the father, they were so easy. Taking this opportunity to crawl out of the pit and be beaten back to the prototype is definitely unacceptable. At this moment, the lawyer proposed to investigate the couple’s hometown to verify that the couple and the girl Is it a relative relationship? After learning the news, the couple was completely panicked."
