Zhang Yu looked at it for a moment and said, "This person is the head of the Peng family you said, this dagger should be the murder weapon, have you done fingerprint identification...... And there seems to be a word written on his right hand, can you judge who the murderer is by relying on this......"

Ni Ni said: "We have done a preliminary identification of the dagger, and the fingerprints on it have been wiped clean. The deceased did write an unfinished word before he died, and through the comparison, it can be intuitively concluded that it was an unfinished 'Yu' character. The third eldest member of the Peng family is named Peng Yu, who is Peng Yan's younger brother, but it is difficult to determine whether the murderer deliberately planted it! ”

"Then this can be judged by whether Peng Yu has a motive for killing Peng Yan, whether the murderer is ...... or not," Zhang Yu said.

"You still need to say this...... Our police have already asked, Peng Yu is mainly responsible for the investment project of Peng's Group, not long ago Peng Yu invested in a huge loss of shares, and even the listed company is in danger of delisting, which made Peng Yan very angry and reprimanded Peng Yu ......" Ni Ni said.

"It's just a business thing, there's no way to make a profit or a loss, and you don't necessarily kill people because you're scolded......," Zhang Yu said.

After saying this, Zhang Yu couldn't help but recall that when he observed with the eye of heaven before, he saw that two of the five people who came out of the house were pushing each other.

If you see this unfinished word after discovering the body, it is estimated that anyone will believe that Peng Yu is the murderer. One of the two people pushing each other must be Peng Yu.

"That's right! After our detailed investigation, Peng Yan was in a very bad mood during this time, and he lost his temper with almost everyone. Among them, Peng Yan's brother-in-law lost 30 million because of gambling, and Peng Yan's wife secretly paid off the debt. Peng Yan's second brother Peng Xian, because of embezzlement of public funds two years ago, was discovered by Peng Yan, and was directly demoted and sent back to Pengjia Village from the vice president of the group. Peng Yan's fourth brother Peng Quan and Peng Yan have always had the best relationship, but someone also found out a few days ago that he had an argument with Peng Yan. We have just conducted an interrogation, and learned that it was Peng Quan who saw that Peng Xian's vice president was removed, and wanted to replace the position of vice president, and proposed it three times and twice, but Peng Yan refused, so Peng Quan was very dissatisfied. Peng Yan's fifth brother Peng Xiang is the illegitimate son of the Peng family, and he has never been treated by his eldest brother Peng Yan, and he has no position in the group, but is only in charge of the strawberry base in the village. After Peng Xian returned to the village, he didn't even have to be responsible for the strawberry base, and he was an idler. Ni Ni introduced.

"Then if Peng Yan dies, who ...... It will be the biggest beneficiary......" Zhang Yu asked.

"A big family like the Peng family is definitely different from ordinary people. But how to do it is actually quite complicated...... According to the normal inheritance law, the biggest beneficiaries are naturally Peng Yan's wife and daughter......" Ni Ni said.

"Is Peng Yan's daughter here?" Zhang Yu asked again.

"His daughter is on her way back to Pengjia Village." Ni Ni said.

Zhang Yu nodded, and said: "By the way, although I am not a law and order, I also like to watch detective TV, when did the deceased die?" This is OK no. ”

"Between half past nine and eleven." This time it was a middle-aged man in a white coat who said.

Zhang Yu: "This range seems to be a bit big......

Without answering in a white coat, Ni Ni said: "The time of death cannot be accurate to every minute and second." An hour and a half, which is already quite accurate. ”

"Okay...... Zhang Yu didn't dare to offend the police tigress, and then said: "Then is there any monitoring here, and what are the people here doing between half past nine and half past 11 o'clock?" ”

"You've got a bit of a brain." Ni Ni said, but pointed to the corpse, "We know that you have two hits, but did you find anything on the corpse?" ”

"The corpse is ......," Zhang Yu looked at the corpse again.

There was only a dagger stuck in the lower abdomen of the corpse, and there was nothing else, Zhang Yu guessed: "The deceased died in his own room, and the person who can enter here must be someone familiar to the deceased......"

"You still need to say it......" Ni Ni pouted.

"That ......" Zhang Yu really couldn't see anything else.

Ni Ni smiled smugly this time and said, "Look carefully......"

She stretched out her hand and pointed to the dagger, and said confidently: "Look at the handle of the dagger, the handle rushes up, this is obviously the shape of the murderer holding the knife with his backhand and the blade piercing downward." And the fatal wound of the deceased is in the lower abdomen, this position, if two people stand facing each other, the murderer holds the knife in his backhand, it is impossible to pierce this position, unless the murderer is a short man who is less than 1.5 meters tall. ”

"Yes......" Zhang Yu suddenly said.

"Also, there's no sign of scuffle here. The deceased did not fight with the murderer before he died, and the murderer made the deceased lose his resistance with a single knife. Ni Ni said again.

Zhang Yu took a deep breath and said: "I don't seem to see such a short person here, if what you say is true, doesn't it mean that the murderer and the deceased are not standing face to face." More likely, the murderer ...... Squatting in front of the dead, or is it ...... Kneel before the dead......"

"You're smart this time!" Ni Ni said solemnly: "Our police have concluded that the murderer must have knelt in front of the deceased before killing the deceased!" ”

In this case, it is equivalent to saying that the murderer must have done something very wrong, so he will kneel in front of the deceased to apologize and ask for forgiveness. However, he took advantage of the deceased's unpreparedness and stabbed the deceased in the lower abdomen with a backhand! Zhang Yu said.

"You're distracted this time!" Ni Ni beckoned to Zhang Yu and led Zhang Yu towards the room on the left.

Inside, this is a study, there is a door behind the desk, the door is hidden, Ni Ni pushed the door open, and entered first. Zhang Yu then went in, and immediately saw that it seemed to be a tea room and a quiet room.

There were only tatami mats on the floor, two futons, a low table, and a cabinet with open doors. There was a pile of books on the table, one of which was on its own.

On the wall opposite the cabinet, there is a picture of the Nine Palaces Taiji.

Zhang Yu's eyes were immediately attracted by the Nine Palaces Taiji diagram, because this diagram is basically similar to the architectural style of Pengjia Village. It can be said that Pengjia Village was built according to this map at all.

Ni Ni saw that as soon as Zhang Yu came in, she stared at the Nine Palaces Taiji Diagram and said, "Can you understand this?" ”

When Zhang Yu heard this, his heart moved, and he said, "You shouldn't let me come because of this......

"Count you smart, otherwise our police will handle the case, what are you looking for?" Ni Ni was straightforward.

"Hehe......" Zhang Yu laughed dryly and said, "Say, what do you want to know......

Ni Ni pointed to the cabinet on the other side and said, "There are traces of someone turning over the study, but according to Peng Yan's wife Lu Ting, after inspection, she found that nothing valuable was missing. Lu Ting only knew that her husband had the habit of writing a diary, and Peng Yan's diary, which we also found in the study, did not find any missing pages, nor did we have any clues about this case. As for what is in this room, even Lu Ting doesn't know, the things in the cabinet are very neat, and it is impossible to judge whether they have been turned over, and we found that they are all ancient books about feng shui...... However, one of the books was not flat, and it should have been held for a long time before it was stuffed into other books, and it was not completely pressed back into its original state...... We have reason to believe that the deceased Peng Yan should have been a person who knew feng shui, and he must have read this book before he died. It is unknown whether Peng Yan put the book back after reading it, or whether the murderer stuffed the book into the cabinet in order to cover up something after killing Peng Yan...... It just so happens that you are a person who understands Feng Shui, so I wonder if you can see any clues from it......"

"If you say that, I'll understand......"
