Watching the ambulance leave the street quickly, the small clinic became lively again. Everyone is asking me what happened, but I am not in the mood to answer these people's questions now.
I looked at the doctor and asked, "I said, is calomel easy to get?"
The doctor nodded and said: "Well, this principle is not difficult. Anyone who knows a little should know it. High school, yes, this kind of knowledge should have been learned in high school. If you want to, high school students should also know it. It can be done. I just don’t know if my guess is correct.”
"Judging from the situation at the scene, it is true." I said.
The doctor smiled and said: "You see, I didn't go to the scene, so I can guess it. Tell me, the principle is not difficult."
I nodded. From the principle point of view, this is not a very complicated way of killing, but it is a very clever way of killing. And that is to say, if the murderer had prepared to install the killing device early on, all the murderer had to do was wait.
Then, the murderer must have understood Wang Xin's character. He knows that Wang Xin is a person who likes to show off very much, especially when there are guests coming, Wang Xin will never miss this opportunity to show off. So Wang Xin found this incense burner from this home that did not belong to him.
Mercury chloride is less toxic, and as long as it is not exposed to sunlight, it is actually very convenient to transport. Put it in the incense burner, wait for it to slowly decompose into highly toxic mercury chloride, and then wait for Wang Xin to kill himself. But this time, the murderer had an unexpected harvest. He might not have imagined that Yang Licheng would be killed like this.
And Yang Licheng originally wanted to hide in Wang Xin's house to avoid danger, but he didn't expect that Wang Xin's house was the most dangerous place. I suddenly thought of something, the murderer killed so many people, but never showed up at the scene, so the previous murder, like this time, used a principle that is not complicated, but it is very ingenious The way to kill.
I frowned, thinking seriously about what kind of person the murderer should be. The murderer is an intelligent man, and the murderer is also a man who likes to think and be alone, and may also like to tinker with some gadgets. And he also knows chemistry. When I mentioned this, I thought of a person, Lu Xiangyang.
According to the testimony of his girlfriend and his best friend, Lu Xiangyang usually likes to study some weird things. Among the three elements of alchemy are salt, sulfur, and mercury.
Then, it is not impossible for Lu Xiangyang to kill people with mercury.
"That's it then!" I said to the doctor, "Thank you anyway."
The doctor nodded, but shook his head again, and then said: "Now, it's not easy to be a doctor. I think that when I was in college, I also had the idea of curing diseases and saving lives. It can be seen that there are too many Do you understand the thing, I have been a doctor for nearly twenty years, and I have seen too many people around me being blackmailed. Especially when facing the matter of life and death, the greed and evil shown by human nature are really shocking Fear, I will never let my son study medicine."
Walking out of the small clinic, I looked at the banner hanging next to the medicine cabinet, "Heal the disease, save the patient, rejuvenate the hand", and I felt an inexplicable emotion in my heart. Perhaps this doctor also has his own story.
Zhao Mingkun said, "I don't think you will go to the hospital with me, do you?"
I nodded and said, "With our current identities, we must have no way to go to the hospital. The doctor revealed the truth to me just now. I am afraid that Yang Licheng and Wang Xin are hopeless. The two of them did not know I inhaled a large amount of highly toxic gas under the circumstances, and did not receive treatment in the first place, I am afraid, I am afraid that I will not survive."
"Life is so fragile sometimes." I said helplessly: "And there is one thing, I don't know if you can see it."
"Which point?" Zhao Mingkun said.
I said, "The air in Wang Xin's house is very poor. So who will be poisoned and who will not be poisoned depends entirely on how much mercury liter is in the incense burner. It can be seen that the murderer did not place a large amount. , otherwise, we would have died a long time ago, wouldn’t we? The murderer has a good amount, so he won’t kill everyone in the room.”
"You mean, the murderer is not a very cruel person?" Zhao Mingkun looked at me and said, "He only needs to kill those thirteen people, and he doesn't want to kill the rest? But what if that's the case?" If so, what happened to Hu Xiaoxue? Hu Xiaoxue was not born when Lu Zhiqiu died seven years ago, how could the murderer not spare even a child?"
I frowned and said, "I've always wondered about this. If Jiang Xiaochun, Hu Pei, etc. are suspected of killing Lu Zhiqiu, but Hu Xiaoxue is innocent, and Jiang Xiaochun didn't die, he just went crazy from fright. That’s all. I’m not sure, but that’s not what I want to say.”
"It's not this?" Zhao Mingkun looked at me.
I nodded and said, "That's right, that's not what I want to say."
"What is that?" Zhao Mingkun asked again.
"Precise." I got on Zhao Mingkun's motorcycle and said, "Precise enough, the murderer's dosage is very precise. He calculated how much dosage he would use to kill Wang Xin. It doesn't matter whether he wants to kill him or not." To kill the rest of the people, I feel that this is more like a habit."
"Habit?" Zhao Mingkun asked.
I nodded and said, "That's right, the truth is already in our hands."
"Then next, we should do..."
Before Zhao Mingkun finished speaking, my cell phone rang first.
"Gu Chen?" I asked, "What did you find?"
The background sound from Gu Chen's side was very chaotic, so Gu Chen said: "I'll send you an address in a while, come here, I've caught Lu Xiangyang."
"Did you catch Lu Xiangyang?" I asked.
"That's right!" Gu Chen's voice was panting, as if he had run for several kilometers, and Gu Chen seemed to be noisy, and he didn't know where it was.
"Now I have something to settle." Gu Chen said, "Hurry over here, if it's later, I'm afraid you won't see me and Lu Xiangyang. Don't talk, I don't have time to chat, I'll give you the address It’s over, you come over right away.”
"Hello? Gu Chen, Gu Chen!"
Gu Chen had already hung up the phone, listening to Gu Chen's words on the phone, it seemed that he was in some trouble. And within seconds, an address appeared on my phone. I handed the phone to Zhao Mingkun, and said, "Go to this place now, Gu Chen seems to be in danger."
Zhao Mingkun looked at me and said, "Isn't he very skilled, what danger can he be in?"
"I don't know, it looks like he's in a hurry, and you heard it too, he caught Lu Xiangyang." I said.
Zhao Mingkun started the motorcycle and drove quickly on the street. She said to me while riding a motorcycle: "That is to say, Lu Xiangyang never went to the south at all. From the very beginning, Lu Xiangyang stayed in Dongxing City. It seems that Lu Xiangyang is quite suspicious. , You said, did he come to such a trick to confuse the line of sight?"
"It's very possible." I said, "This case, speaking of it, is simply a coincidence between us. If we look at it according to the normal process, Hu Pei's death will definitely take a few days or at least one day." People will find out, so if you follow this clue to investigate, it will be at least one day later than us."
"That's right." Zhao Mingkun nodded.
I continued: "If we look at it from this perspective, we know that what happened to Lu Xiangyang will be at least tomorrow. So many people have died now, except for the four women in that dormitory who have not died yet, the rest All of them are dead. Say, if you give Lu Xiangyang another day, those four women will probably be killed by him too."
Zhao Mingkun looked at me through the rearview mirror and said, "Then you really think Lu Xiangyang is the murderer?"
"This point, I don't dare to guarantee it yet!" I said: "But whether Lu Xiangyang is the murderer, we have already found him. If he is not the murderer, he can at least prove his innocence, right? However, Actually, I don't think Lu Xiangyang is the murderer."
"Why?" Zhao Mingkun asked.
I pointed to my chest and said, "Intuition and clues. There is too much age difference between Lu Zhiqiu and Lu Xiangyang. Lu Xiangyang doesn't seem like someone who knows his sister and classmates. Lu Xiangyang has no intersection with these people at all. Among these thirteen people, I have never heard of any one who mentioned how Lu Zhiqiu's younger brother Lu Xiangyang is, which shows that they probably don't even know who Lu Xiangyang is."
"Is that place far from here?" I asked, "You'd better drive faster."
Zhao Mingkun snorted coldly, and said, "Do you know why I like riding motorcycles and not driving cars?"
"Why?" I asked.
Zhao Mingkun said, "Hold me tight."
I nodded and hugged Zhao Mingkun tightly.
And when I hugged her tightly just now, I saw Zhao Mingkun lifted the front wheel of the motorcycle, and when the front wheel landed again, I felt that I was not riding a motorcycle. It's not driving too fast, it's flying too low.
The wind shattered Zhao Mingkun's words: "Because the speed of the motorcycle is faster, and there is no need to worry about traffic jams."
I said: "You should slow down, this is too fast, if a car drives out, you will have no time to hide."
Zhao Mingkun laughed and said, "Didn't you tell me to drive faster?"
"It's too fast..."
