Siheyuan: I have a system and I smile with satisfaction

Ni Daguo was speechless. Was he showing off?

Ni Daguo said to the local police: "Can you please bring all the physical evidence to us?"

The police did not make things difficult for Ni Daguo, nor could they have done so.

Ni Daguo picked up the sealed dagger. It didn't look gorgeous, but it was quite sharp.

He asked Wei Zongze, "Look carefully, is this dagger yours?"

Wei Zongze shook his head. "I don't know. I told you, I have a lot of daggers. I usually just pick one up to kill chickens, ducks, pigs, etc. I can't tell whether it's mine or not."

Ni Daguo was simply speechless.

This guy is causing trouble for him.

But no matter whether this dagger belongs to Wei Zongze or not, Wei Zongze is a suspect.

If it is his, it may prove that he brought the dagger with him. If it is not his, then it belongs to his cousin Wei's house, and he just picked up the dagger and killed people.

The main thing is that Wei Zongze didn’t know whether the dagger was lost, and Wei Zongze’s wife didn’t know either.

Normally she doesn't pay attention to Wei Zongze's weapons.

No wonder the local police thought Wei Zongze had killed someone.

Wei Zongze snorted, "I always do things in a way that if I did it, I admit it. If it wasn't me, I would never admit it even if you kill me. If you want to force a confession, you can come. If I confess under coercion, I'm not a hero."

Since Wei Zongze retired to live a secluded life, he has never cared about what the outside world is like. He didn't know that Lou Bancheng had met Ni Daguo, and he didn't know Ni Daguo.

Of course, I thought Ni Daguo was one of the people who interrogated him.

"Haha, so this is what a hero is? The greatest heroes serve their country and their people, so do heroes. What's wrong with you? If someone hadn't invited me here, I wouldn't bother with you."

Whether it is Lou Bancheng or Wei Zongze, they were once influential figures in both the black and white worlds, but have they really brought any benefits to the people? Have they really made any contributions to the country?

There seems to be none.

All we can say is that they are self-proclaimed heroes.

Ni Daguo never thought of himself as a hero because he couldn't do it.

If you want to be a hero, you have to give a lot for your country and your people, even sacrifice yourself.

Wei Zongze was stunned. "Who invited you here? The head of the Lou family?"

Ni Daguo nodded, "It's good that you know. So, you cooperate with me. If you really didn't kill anyone, I will clear your name."

Wei Zongze then sat up straight, which showed that he still respected Lou Bancheng very much.

Of course he had to actively cooperate with the people invited by Lou Bancheng.

Ni Daguo handed the dagger to him again, "Look at it carefully, think about it carefully, can you remember whether this dagger is yours?"

Wei Zongze really looked at it carefully for a long while before saying, "This pattern looks familiar. It seems like I used this knife to kill a snake and make snake soup before."

"Did you clean the dagger?"

"I don't usually clean them. My daggers are all good daggers. They won't get stained with blood. After the killing, it just flows down the blade."

Ni Daguo compared the test results and found that in addition to Wei Dalong's blood, the dagger also had the blood of his cousin Wei and DNA suspected to be snake blood.

Although DNA technology is still in its early stages, it is still possible to basically find out the general idea.

Therefore, based on Wei Zongze's words, we can judge that this dagger belongs to Wei Zongze.

Because, it shouldn't be such a coincidence that Wei Dalong's family also happens to use a dagger to kill snakes and eat their meat.

But this is not necessarily the case, what if it is just a coincidence?

"Also, the daggers I bought were all from an old master. The daggers and knives he made were very sharp. You can go and ask him if this dagger was made by him."

Sure enough, because Ni Daguo was introduced by Lou Bancheng, he said more and was quite cooperative.

Ni Daguo asked the police to investigate, but he did not find any DNA of Wei Zongze in Uncle Wei's home in the files, which means that no trace was left.

This is very unusual. Could the murderer have erased all traces so completely?

Ni Daguo went to see the body.

The autopsy report is out, and it was death caused by external force.

There was no blood of outsiders on the body, even the blood of the family of three, and no DNA from other people.

Ni Daguo once again felt that his perception was correct, and it might be caused by mutual slaughter.

But this cannot be used as actual evidence. We still need to find actual evidence.

However, since Wei Zongze said that the dagger might be his, it can be assumed that it was Wei's cousin's family who stole their things, including the dagger and the jade pendant.

Then it can explain why Wei Zongze's DNA was on the dagger.

Ni Daguo carefully observed the scars on the body.

Then he simulated the situation at that time, where Uncle Wei discovered that Wei Dalong was stealing something and wanted Wei Dalong to return it, but Wei Dalong refused. After all, the jade pendant looked valuable.

Maybe you can get rich by selling this jade pendant.

Then an argument broke out. Uncle Wei wanted to return the things to Wei Zongzeze, but Wei Dalong got angry and took out a kitchen knife to threaten Uncle Wei.

Uncle Wei insisted on returning it, and Wei Dalong ended up taking action.

Although the first two stab wounds from Uncle Wei did not cause his death, he was seriously injured and fell to the ground, covered in blood. Aunt Wei heard the noise and ran out of the house to stop Wei Dalong.

Wei Dalong became even more angry. He thought he had killed his uncle Wei, so he made up his mind and killed his aunt Wei.

Aunt Wei died without much struggle.

Wei Dalong wanted to take the things and run away.

Uncle Wei fell to the ground, but he was not dead yet, and he grabbed his trouser leg. Wei Dalong kicked Uncle Wei twice and stabbed him with the dagger, but Uncle Wei did not let go, so he pulled hard on the trouser leg and tore off a piece of it.

Who knows, I might use too much force and fall forward.

Who knew that when he fell down, the dagger would pierce his chest and kill him.

Ni Daguo's powerful mental strength made his thinking quick, as if he was at the scene and simulated the situation at that time.

But such evidence is still insufficient.

He carefully checked and sensed the time of death of the deceased and found that the time of death was between 3 and 5 pm three days ago.

Not the night as previously judged.

Moreover, it is unknown what factors caused the forensic doctor to make an error in determining the time of death.

Ni Daguo once again wondered if there was any mistake during the on-site inspection?

Ni Daguo suddenly thought that the temperature had dropped by more than ten degrees in the past few days, which was extremely cold. Then the open windows of the deceased's home...

Ni Daguo specifically called the police who were inspecting the scene at the time and asked, "When you went there, were the windows of the deceased's home open?"
