After Du Wei came out of the kitchen, I got up from the sofa.

"What are you doing, Captain Zhou?" When Du Wei saw my movements, he asked me, "Why are you still standing up?" Sit back and relax! ”

"It's not too early, it's eight o'clock in a while, and I have to go back." I greeted Du Wei, and Lao Zhang also stood up.

"Anyway, you came in a police car, and you'll be back in a while, I finally have time to discuss the situation of this case with you, and you're leaving again, playing for a while?" Du Wei kept me and Lao Zhang, and let us play for a while.

Naturally, we won't, Lao Zhang also knew why I was in such a hurry, so he said this for me, "Du Wei, it's not that the two of us don't play anymore, it's really not early, and besides, Captain Zhou's wife is still lying in the hospital, and he also wants to go back to accompany his wife in a hurry, so don't keep us." ”

"Yes, I haven't asked my sister-in-law for so long, my sister-in-law is in the hospital, how is she doing? Are you better? Du Wei asked me with great concern about Huang Na's situation, "I'm really sorry Captain Zhou, I have asked for so long." ”

"It doesn't matter, he's fine, it's all some skin injuries, and it's almost fine now." I said to Du Wei.

"Then I won't keep you, you two slow down, be careful on the road." Du Wei said to me and Lao Zhang.

"Got it!" Lao Zhang and I walked out the door while also greeting Du Wei.

Back at the place where the police car was placed, I drove the police car and Lao Zhang back to the police station first, and then rode a bicycle to the hospital.

When I arrived at the hospital, it was almost nine o'clock, and the two mothers and Huang Na were chatting.

After seeing me come in, Huang Na immediately asked with great concern, "Zhou Cheng!" Why are you here now? Did you go to investigate the case again? Did you have dinner? ”

"That's right, the case was dragged out, so I just came here now, and I just had dinner at my colleague's house." I walked over to Huang Na's bedside and took out the oranges I had bought for her yesterday, peeling them for her while answering a series of questions.

We didn't say anything after that, and the day passed like this, and the next day came again as usual.

I arrived at the police station early, and after finding Lao Zhang, I showed him the thing I got from Du Wei yesterday.

"What are you showing me this? What is it? "Lao Zhang looked at the thing in my palm and didn't figure out what I meant?

"Think about it, what is the murderer's modus operandi? Combine this with this, and you'll understand what I mean by showing you this thing. I put it back in my pocket and said to Zhang.

"Oh! Oooooooooo......oo I understand! Lao Zhang raised his right hand excitedly, and then said to me, "So that's what happened."

Later, Lao Zhang asked me again, "Zhou Cheng, where did you find this thing?" When was it discovered? ”

"I found this thing in Du Wei's house yesterday!" I answered Lao Zhang's doubts.

"Du Wei's house! What does he want this thing for? Can you bring it to me and see what this thing is for? Lao Zhang felt very incredible, "If this is his murder weapon, then how can he be stupid enough to leave it at home instead of disposing of it early?" This doesn't look like Du Wei's style of doing things! ”

I handed it to Lao Zhang's hand, and Lao Zhang took it and looked at it, and then took it over to look at it, looking like he couldn't see it through.

"This shows that Du Wei doesn't know this thing, when I found this thing, it was in a very inconspicuous place next to the TV, and it is estimated that Du Wei himself didn't notice this thing." I analyzed it for Lao Zhang, and I think it is the most likely and convincing reason.

"Wow, that's incredible!" Lao Zhang sighed, his eyes were still looking at that one thing, "You said that such a small thing can kill you, human life is really too fragile!" ”

"I remember Du Wei told me an example before, he told me that when he used to follow his master, did he tell him that only 1mm of notebook paper can kill people, and there are toilet paper and silk that we often use, which were used for torture in ancient times." I gave Lao Zhang an example of how fragile life is.

"How do you do these things? What can this little thing be used for? Lao Zhang still looked at the thing like a murder weapon, and his head was completely 100,000 whys.

"A haomi's notebook paper is sometimes sharper than a knife; In ancient times, the torturer put silk on the face of the prisoner, and then poured water on it, and slowly could not breathe freely, and then he would die. I still answered carefully, his 100,000 why, "As for what this thing is used for, if my guess is correct, this thing should just be used to wipe the wrong place written on the pencil, similar to an eraser!" ”

"Wow! It's amazing! "Lao Zhang, still sighing there about the murder weapon.

"Lao Zhang, don't sigh at the magic of this murder weapon, tell me first what you think about this matter? I want to make a reference to decide what we do next? I said to Lao Zhang.

Lao Zhang looked like he had never seen the market, which is not surprising, he was seven or eight years older than me, and his education level at that time was limited there, and I was welcome to learn a little more than Lao Zhang knew.

And I have too many inferior places compared to Du Wei, although I am only three or four years older than him, but he has studied abroad, and I only rely on some of the things I learned, and some things I learned from reading books, which are completely incomparable with him, after all, in our time, the level of education abroad, and the level of other aspects, are much higher than ours.

"My opinion is that since Du Wei didn't know about the murder weapon, it means that he was not involved in this matter, but the murder weapon was found in his room, which shows that there is a 99% probability that he is harboring the murderer, and there is a high probability that the murderer lives in his home." Lao Zhang told me and expressed his opinion.
