I thought of someone who could help me, it was eight o'clock in the evening, if nothing else, there was still time, I took out the phone and called Brother Yin, and it didn't take long for the phone to ring before Brother Yin's voice came, "Xiao Han, what's the matter with me at this time?" I said to Brother Yin: "Brother Yin, I think I already know who the murderer is, but I don't have any tangible evidence in my hands to prove it now, I have an idea, if nothing else, I can get tangible evidence, but I need help." Brother Yin let out an "oh" in surprise, and then said, "What do you need me to help you?" "I thought about it. Then he said to Brother Yin: "Brother Yin, I want to ask you to help me contact Wang Dashan, when I left you today, I had a little trouble with him, and I don't have his contact information, I want you to inform him and ask him to call me back, or come directly to my bedroom to find me, quietly, as soon as possible, there is not much time." Brother Yin didn't ask anything, but replied to me briefly, "Got it." ”

After hanging up the phone, I sat down at the computer desk, carefully planning the plan to be carried out tonight, and there were no flaws, if I failed, maybe it would be very difficult to investigate in the future.

After waiting for about five minutes, an unfamiliar phone number appeared on my mobile phone screen, I answered the phone, and Wang Dashan's voice came from the other side of the phone, "Xiao Han, what are you looking for me?" The voice had a hint of displeasure, and I said directly: "I think I know who the murderer is, but there is no evidence in my hand, I have a plan now, and I need your help." After a while of muttering on the phone, I didn't know what I was thinking, and then I continued: "I know that you have always wanted to enter the Criminal Investigation Department and be Brother Yin's deputy, I don't want to compete with you for this position, as long as you help me solve this matter, rescue Xue'er, and solve the case, I can give you all these credits, and I will also quit the Criminal Investigation Department." After I finished speaking, Wang Dashan asked in surprise on the other side of the phone, "Are you sure what you said?" I quickly replied into the microphone, "Well, I'm sure, I'm vouching for my personality." Wang Dashan on the other side of the phone said: "Okay, I believe in your character, I still believe in Brother Yin's vision, say, what do you want me to do?" I tapped the desktop with the tip of my pen, thought for a while, and said to Wang Dashan: "I need the clothes that Zhu Ganglie wore when he died, and help me get some LSD (a type of hallucinogen, which can hallucinate when guided.'" And a camera, be fast. After listening to my request, Wang Dashan said to me: "The camera, and Zhu Ganglie's clothes, it's okay to get them, the clothes are in the morgue, the camera, I have it at home, but I need some time for the LSD you want." "How long will it take you?" I asked, Wang Dashan was silent for a while, and then said to me: "Half an hour, at most half an hour, I can get the medicine you want." I thought about it for a moment and said to him, "Okay, I'll wait for you in my dormitory for half an hour, you know where my dormitory is." Wang Dashan said: "I know, I went once, but you were not there at that time, and I went to your bedroom to look for you half an hour later." With that, he hung up.

While waiting for Wang Dashan, I made a phone call to Tang Long, chatted with him for a while, asked him where he was, and asked him to go out for a drink in half an hour.

About half an hour later, that is, about twenty minutes, there was a knock on the door of my bedroom, I looked at the door, there was Wang Dashan standing outside, what I wanted, he was ready, I took the thing, and took out a small bottle of white powdery stuff from it, I knew that this thing was the hallucinogens I wanted, and it was also an essential thing tonight, Wang Dashan asked me what I was going to do, I didn't tell him, but handed him the things I had written before, Wang Dashan looked at it and nodded, I nodded at him and told him that everything should be done quietly and not be discovered. Wang Dashan looked at me, a little speechless, but in the end he didn't say anything, turned around and went to prepare for tonight's plan.

I also went out of the dormitory, and after locking the dormitory door, I rubbed my cheeks to try to relax as much as possible, and then took a taxi to the vicinity of the hotel where Tang Long lived.

After arriving at the place, I found a fairly conspicuous restaurant, and then made a phone call to Tang Long, telling him that I was in a restaurant near his hotel, and asked him to come to me, and then called Wang Dashan again, telling him that after Tang Long came out, he would immediately go to implement the plan, and when it was completed, call me.

Sitting in a remote corner of the restaurant, I asked the waiter for a pot of boiling water, melted the hallucinogens prepared in advance with boiling water, and put a small glass of slightly white solution in front of me, and then poured out most of the cup of hallucinogens, leaving only a thin layer at the bottom of the cup, although the amount is small, but it is enough for an adult to have an effect, and the effect of LSD is about 30~40 minutes, which is enough time for Wang Dashan to prepare.

After making these preparations, I stared at the door of the restaurant, and not long after, Tang Long pushed open the door of the restaurant and walked in, and before he could reach my table, I naturally poured the beer into his cup, fused with the hallucinogen, without a trace, no matter how it looked, it was just an ordinary beer.

Tang Long sat in front of me, looked at me, and said, "Third child, what's wrong with you, why do you look so haggard today." I thought to myself, "You're embarrassed to ask me, if you hadn't done so much and made me spend the past few days in exhaustion, would I be so haggard!" But I just thought about it in my heart, but I couldn't say it, I said: "There are too many things in the past few days, and good people can't stand it, Xue'er's whereabouts are unknown, and I can't sleep all night, where can I have a good face." Tang Long listened to my words, sighed, and said to me: "Third child, look away, don't burn yourself, your body is the most important thing, you are like this now, even if Xue'er comes back, I don't want to see you." "Speaking from the heart, if it weren't for the letter left to me by the head of the dormitory, I really don't want to believe that Tang Long would hurt me and participate in the kidnapping of Xue'er, but the facts are the facts, and they will not change by personal will. I also sighed and said to him, "I'd rather Cher ignore me and do anything as long as she's okay." After speaking, I didn't wait for him to say anything, raised my wine glass, and said to him: "We brothers in the dormitory, why did it become like this, now I am the only one left in that dormitory, come, accompany me to do one!" Tang Long picked up the wine glass, touched the glass in my hand lightly, drank the beer in his hand, and saw this, I knew that tonight's plan was half successful, now just pull him back to the hotel before the hallucinogens he drank took effect.
