Lin Jue invited Yang Xiu and Yu Deshui to go with him to Li Yuanwai's house to inquire about the situation. Yang Xiu and Yu Deshui saw that Lin Jue was confident, and they were also very interested, wondering why Lord Lin was so sure that the case had been solved, so they happily went. When they arrived at the Li family, the Li family took Lin Jue and others to the house where Li Yuanwai mysteriously died. He called the servants of the Li family and asked a few words, and then showed a satisfied smile.

"Brother Lin, what's the matter? How do you look like you don't look like an investigation at all, so can you solve the case? Yang Xiuxiao asked.

Lin Jue said: "Brother Yang, Lord Yu, the case is really solved." I already know how Li Yuanwai died, and I also know his murderer. ”

"Who's the murderer?" Yang Xiu asked hurriedly.

"Don't be busy, let's go back to the yamen, let's do an experiment, and you will know everything." Let's go back to the yamen. Lin Jue waved his hand.

On the way, Yu Deshui couldn't help but ask: "My lord, since you know who the murderer is, why don't you arrest him immediately?" The adults said this in front of the Li family, if they were murderers, wouldn't they run away immediately? ”

Lin Jue smiled and said: "Lord Yu, you don't have a good brain, if they are murderers, why didn't they interrogate them before?" Just by my words, they scared away? As soon as they ran, weren't they convicted of the crime? Besides, the murderers are not them. ”

Yu Deshui easily mustered up the courage to ask, but he was said to have a bad brain, so he had to blush and remain silent. He really had a bad brain, and he didn't know what Lin Jue was doing during the whole process.

……

In the courtyard of the yamen of the Criminal Division, all the officials gathered around to watch the excitement. According to Lord Lin's instructions, Lao Wu took people to the street to catch a wild dog and came back, and at this moment he was chained to the stone mill in the yard. Lord Lin said that he wanted to do something, and this matter could catch the real murderer who killed Li Yuanwai, which made everyone wonder if Lord Lin was crazy. Therefore, when they heard the news, they came and watched.

"My lord, according to your orders, the storehouse has been cleaned up. What else do you command? Yuan Zhutou walked briskly from the west head and reported to Lin Jueyu, who was standing there making eye contact with the wild dog.

Lin Jue nodded and asked, "Are the doors and windows sealed?" ”

"It's all right, it's not airy, only a little gap between the doors and windows, but it's no way." Yuan Zhutou said.

"A little bit of a gap doesn't hurt. Lao Wu, pull the dog to the storeroom and leash it. Lin Jue commanded.

Lao Wu agreed, stepped forward and grabbed the rope and dragged the howling wild dog to the warehouse, and everyone followed behind, full of questions. Lao Wu forcibly dragged the wild dog into the house and tied it to a wooden stake in the middle of the house.

"Did you buy the meat buns?" Lin Jue left and right four advisers.

"It's coming, it's coming, it's been bought. It's hot. A servant squeezed in with a plate of meat buns.

Lin Jue reached out and grabbed a meat bun and ate it in two bites, and said, "It tastes good, the meat is very fresh." ”

Yang Xiu scratched his head and said, "Brother Lin, are you hungry?" ”

Lin Jue smiled: "I ate breakfast and was not hungry. This bun was bought for this dog. The poor was born as a stray dog, and he probably hasn't eaten a few full meals, and everyone shouts and beats him on the street. This plate of steamed buns, let's eat it all. Take it. ”

Everyone rolled their eyes in unison, what is so pitiful about a leprosy dog, and adults are also very sentimental, these sighed. The people of the meat buns didn't have the money to eat, but they fed the dogs.

The old servant put all the meat buns in front of the stray dog, and when he turned around, the dog had already begun to eat in a big gulp. In a few moments, eight or nine meat buns were eaten cleanly by it. Having eaten his fill, the dog visibly settled down, licking his tongue and lying in the middle of the room.

"Hey! The beast is at ease, and makes this place his home. Lord Lin, what kind of medicine are you selling in your gourd? We're all confused. Yu Deshui said.

Lin Jue smiled and ordered: "Old Wu, make a brazier and put it in the house, and then lock the doors and windows, you personally guard here, and no one is allowed to open the door and enter." You are not allowed to go in, nor are you allowed to go in if you hear any movement, do you hear? ”

The crowd rolled their eyes even more. Adults are also too good to this leper dog, give it meat buns, and are afraid that it will be cold, so make a brazier to warm up. What kind of dog luck did this leper dog go? Is it difficult to provide for it? The adults said that they wanted to catch the murderer, how could they get a dog to serve as a father? These two things are incompatible.

But if you don't understand it, you still have to do it. Immediately, someone made a brazier and moved it into the house and put it in the corner. The doors and windows were closed and locked, and Lao Wu led people to guard outside.

Lin Jue personally supervised the completion of these things, waved his hand and said, "Scatter and scatter, do things." ”

"My lord, where is the murderer? What about the murderer of Li Yuanwai that you are talking about? Why didn't you see it? "Yude Waterway.

Lin Jue smiled and said, "Lord Yu, you can't eat hot tofu in a hurry." Do things first, and I'll show you who the killer is in the afternoon. ”

Everyone dispersed suspiciously, from noon to afternoon Shenshi, more than three hours, everyone actually didn't have much heart to do things, all they were thinking about what Lord Lin was doing, and they were all waiting for the mystery to be revealed.

Finally, halfway through the Shen hour, Lord Lin came out of the public house and walked into the courtyard to stretch. Almost instantly, all the officials rushed out and gathered in the courtyard, looking at Lin Jue with blank eyes.

"What for?" Lin Jue glared at everyone.

"My lord, don't play dumb riddles. Everyone is dying. I don't have the heart to do anything," Lao Wu said with a smile.

Lin Jue rolled his eyes and smacked his lips: "That's it, then I won't play dumb riddles with you, it's really a bunch of anxious people, and I don't know if the time is enough." Come on, open the storeroom, and see what happened to the dog. ”

Hearing this, everyone couldn't wait to come to the door of the storeroom, unlocked and opened the door, and a hot air sprayed out, which was a little pungent and unpleasant.

"Phew!" Lao Wu fanned his nose and frowned.

"How's the dog?" Lin Jue asked.

"It's a good night's sleep, this beast, it's so comfortable." Lao Wu scolded.

"Oh? Let's get it out. Lin Jue said with a smile.

Lao Wu answered, entered the house, and suddenly let out a surprised cry: "Huh? What's going on? ”

"What's wrong, old Wu?" The crowd asked, stretching their necks.

"Dog...... The dog seemed to be dead. Lao Wu said in a trembling voice.

"Huh?" The crowd was in an uproar.

Lin Jue said: "Lift it out and put it outside." ”

Lao Wu hurriedly beckoned someone to carry the dead wild dog out, and Lin Jue ordered them to put the dog on the grinding plate. Everyone gathered around to look at each other and talk about it.

"How could he die? Good end-of-the-road. There was food and drink, and a brazier was made, why did he die? ”

"yes, weird. Oh, you see, this dog's stomata bleed, didn't he die of poisoning? Could it be that the bun was poisonous? ”

"You pull your daughter-in-law's thigh? Lord Lin also ate steamed buns before, wouldn't adults also ...... if it was poisonous?"

"Oh, yes, Lord Lin also ate the buns, it can't be because the buns are poisonous. What's going on here? What the hell? The good ones died? ”

Lin Jue smiled and pinched his chin, listening to the gossip of the officials around him. Yang Xiu frowned and said, "Brother Lin, what the hell is going on?" ”

Lin Jue coughed, and the people around him stopped listening one after another. Lin Jue said: "Everyone, the murderer who killed this dog is the murderer who killed Li Yuanwai. Master Qin, read the transcript of the scene investigation file of the murder of Li Yuanwai. ”

Master Lao Qin hurriedly went back to the public room and took out the dossier and read it aloud: "...... The time of his death was in the middle of the night, bleeding from his mouth and nose, and the blood was rose-red, but there were no scars on his body. It seems that he was poisoned and killed. The doors and windows of the house were closed, and there was no sign of a fight. The family property is in good condition. The furnishings in the room are no different. There was vomit next to the collapse, and there was a pot of charcoal, which had burned out. ……”

"Alright." Lin Jue raised his hand and said, "That's it." You all heard that when Li Yuanwai died, the doors and windows were closed, and there was a burned brazier in the house. It's similar to what I designed today. The dog was also in a sealed room with the doors and windows closed, and I made a brazier for him, and then you see, the dog died. Look at the dog's mouth and nose, and it is bleeding from the pores. This blood color is mixed in the hair and it is not very clear, Lao Yuan, make a cut on the dog's leg, let's take a look at the blood. ”

Yuan Zhutou drew a knife and cut a small cut on the dog's leg, and suddenly blood droplets dripped down, dripping on the ground like splashing plum blossoms. The color turned out to be really rose-red, and it felt very weird.

"See? The blood shed by a normal person is red, and when it dries up, it will be black and purple, and this blood drop is rose-red, which is the same color as the blood of Li Yuanwai recorded in the dossier. It can be seen that the cause of their death is also the same. Someone said that the dog died of poisoning, which is half true. It was indeed poisoned to death, but there was no poison in the bun, I ate the bun, you see, I didn't have the slightest sign of poisoning. The culprit is someone else. Lin Jue said slowly.

Yang Xiu shouted loudly: "I understand, what Brother Lin means is that the cause of Li Yuanwai's death is the same as that of this dog." Is there a weirdness in that brazier? Someone threw poison into a brazier? The smell of burning poisoned people? ”

Lin Jue laughed and said, "Brother Yang, your brain hole is too big. However, what you said is not entirely wrong, it is true that there is a strange thing in the brazier, but no one puts poison into the brazier, but the poisonous gas in the charcoal fire itself. This poison is called carbon monoxide......"

“…… What eggs? The crowd asked, rolling their eyes.

Lin Jue smacked his lips and said, "What do you say?" When the charcoal fire burns, there is a smell that irritates the nasal passages, which is a poisonous gas produced by the charcoal fire. A small amount of this poisonous gas is harmless, but if it gathers too much, it will poison people and die. Especially in a room with closed doors and windows, as the charcoal fire in the brazier burns, this poisonous gas will slowly accumulate, and eventually people will be killed in their sleep. And the most obvious feature of the poison of this poisonous gas is that the blood is rose-red. The color is delicate, different from the normal color of blood. That's the color of this poisonous gas fused into human blood. When he dies, he will have symptoms of stomatal bleeding, and it is easy for people to mistake him for poisoning. This is exactly the reason why Li Yuanwai was murdered in the previous file. But in fact, the murderer is not a person, but this poisonous gas. The brazier burned out in Li Yuan's outer house, and the brazier burned out in the warehouse house today is the culprit. That's the mystery. ”

Everyone stood there dumbfounded. Their first reaction was: nonsense. But after careful consideration, I found that there was no refutation. Lord Lin actually restored the environment of the scene where Li Yuanwai was killed today. No one touched the dog after it was chained to the house, but it just died in good shape. And the blood on his body is rose-red, which is the same as the blood of Li Yuanwai recorded in the dossier. If the cause of Li Yuanwai's death was different from that of this dog, then why did all the characteristics be the same? How does this explain?

"I know you have a hard time understanding. That's why I did this experiment to restore the scene of the case, which is to restore the truth. The reason why Li Yuanwai's death became an unsolved case was because he had no enemies, and the second was not to seek money and kill him, and everything was safe when he died, and there was no trace of the murderer. If you can't find the murderer, could it be that the ghost killed him? I looked through the file and found that the time of the crime was Layue, and when I saw the blood in the record, I estimated that there must be a brazier in his room that night. So this morning, Lord Yang Xiu and I went to Li Yuanwai's house again and specially investigated the scene. Li Yuanwai's house was renovated once last spring, and the doors and windows have sealed wooden strips, and the window paper is intact, which can be described as airtight. The weather is cold in winter. It is also common for the bedroom to be sealed and make a fire. The servant who found Li Yuanwai dead told me that there were two pots of charcoal fire in Li Yuanwai's room that night, and when he smashed the doors and windows to enter, there was still a strong charcoal fire in the house, and the servant had dizzy afterwards. It's just that when the people from the government arrived, the smell in the house had already dispersed. A sealed room, two pots of charcoal, poisonous gas gathered, Li Yuanwai was poisoned in his sleep, and the seven orifices bled to death. The murderer was none other than these two pots of charcoal. The same is true for this dog, because the warehouse is not big, so I only put a pot of charcoal fire, and the dog died in it. The situations are similar, the death is similar, and the blood is the same. The cause of death must also be the same. Isn't this case solved? Hahaha. ”

Lin Jue burst out laughing. The fog in everyone's hearts blew away, and they finally realized that there was no longer any doubt. After thinking about it, some people spontaneously applauded.

The official Lao Wu shouted: "It's strange that when I entered the house, my head was a little dizzy, is it because the poisonous gas inside has not dissipated?" The villain won't be poisoned. ”

Lin Jue said with a smile: "Don't worry, this poison doesn't smell it and die, otherwise everyone wouldn't have to roast it." It accumulates slowly, you come out and breathe in new air, and after a while the dizziness goes away, and it recovers. ”

"Oh, then I'm relieved." Lao Wu wiped his chest and breathed a sigh of relief.

"Wonderful, wonderful, who would have thought that this is the reason. Just by going to the murderer, how can you find out. This unsolved case, however, turned out to be no murderer, but just the poison of charcoal. Brother Lin is knowledgeable, which is really eye-opening. Yang Xiu smacked his lips and sighed.

Lin Jue laughed and said, "Luck, luck." Luckily, I know that this gas can kill. I still remember when I was a kid and my mother always told me to open half of the window when I was burning charcoal in the winter. Or leave some gaps between doors and windows. Most of us do the same because we don't want to kill people with charcoal gas. It's just that when we investigated the case, we forgot about this reason and did everything we could. ”

"It's really...... When you say this, I also think of some things, when I was a child, someone died in the big family in the village for no reason, and I couldn't get the murderer after tossing for a few years. Now it seems that perhaps it is for this reason. My family is poor, and I can't afford to burn a charcoal pot in winter, so it seems that being poisoned by this charcoal fire will require a rich family to become it. The poor can't afford to burn a charcoal pot, but they won't die because of it. Yang Xiu said with a smile.

When the officials heard this, they inexplicably felt some pride. It turns out that poverty is not all bad. At least this kind of death will not fall on your head. Although the house is cold in winter, at least it will not be a corpse after sleeping.

"Lord Lin, there is something that the lower officials don't understand, why did Lord Shicai send a plate of buns to this dog? Could it be because Li Yuanwai also ate steamed buns before he died, and this poisonous gas attack has something to do with what he ate? Yu Deshui asked.

Lin Jue laughed and said, "Lord Yu thinks too much, this has nothing to do with what you eat." ”

Yu Deshui said: "Then why do you want to do this? If it weren't for the adults who ate a bun in front of everyone, we would all think that the bun was poisonous. If it is a restoration, why make variables? If someone doubts that the one the adult eats is not poisonous, but the other buns are poisonous, wouldn't it be impossible to support the adult's claim? ”

Lin Jue laughed and said: "I'll say it again, if you don't eat steamed buns, this dog will be poisoned by charcoal fire." The reason why I bought a plate of buns for this dog to eat was because ......"

Lin Jue paused, stretched out his hand to wipe the messy hair on the dog's body, and sighed lightly: "That's because ...... I knew it was going to die, so I wanted it to have a good meal before I died. Heaven has the virtue of a good life. Although the life of animal mosquitoes is low, it is also a life. I want to take its life, and I can't let it eat before it dies. In the next life, you will be reincarnated as a human being, and you will run faster when you are full. ”

When everyone heard this, they secretly praised it in their hearts. It turned out that Lord Lin was so kind-hearted that he even took pity on a dog's life, and it seemed that he was following the right person. If it's good for dogs, can it be bad for people?

"Well, I declare the case solved. The master recorded the process of solving the case and handed it to me to see. In addition, this case may not be a separate case, Lord Yang, I hope that the two of you will immediately go through all the cases and see if there are any similar cases. Perhaps, there are the same cases that have not been solved, and this time it may be possible to solve multiple unsolved cases at the same time. Lin Jue laughed loudly.

Yang Xiu and Yu Deshui were refreshed when they heard this, not to mention, there was really such a possibility. Since this case has not been solved in Kaifeng Mansion, it is difficult to guarantee that there are similar cases in the previous unsolved cases, and it is difficult to find it.

So Yang Xiu and Yu Deshui immediately began to search and flip through, and sure enough, the next morning, when Lin Jue came to the yamen, Yang Xiu put a stack of files in front of Lin Jue's desk with red eyes. After Lin Jue read it carefully, these five headless unsolved cases were extremely similar to Li Yuanwai's death, and they basically met the characteristics of carbon monoxide poisoning death.

In order to further confirm, Lin Jue spent two days at the scene of the case to collect evidence and testimony, supplementing evidence such as weather, doors and windows, charcoal fires, and witness testimony that the government had ignored in the previous investigation. In this way, with the addition of Li Yuanwai's case, within six days, six unsolved cases spanning five or six years were solved, and the speed of solving this case is simply superb.

On the morning of the eighth day of the first month of March, Lin Jue brought the file and asked to see Zhu Zhirong, the governor of Kaifeng Prefecture, and reported to Zhu Zhirong the circumstances of cracking the six cases. When Zhu Zhirong heard that Lin Jue had cracked six cases, he didn't believe it at all. When Lin Jue presented the investigation process and various evidence one by one, and made a detailed explanation of the case and some popular science, Zhu Zhirong finally believed that the six cases were really solved. Although these six cases are not big, they are only six cases of dead people years apart, but the impact is actually not small. Because the cause of death is unknown and the murderer is nowhere to be found, it has caused a lot of panic among the people, and serial killings and what ghosts and ghosts are asking for souls are flying all over the sky, bringing a lot of pressure. Zhu Zhirong has also been reprimanded many times by the Political Affairs Hall. I didn't expect it to be broken like this.

Zhu Zhirong immediately ordered someone to investigate the case and report it to the imperial court. Two days later, the imperial court sent someone to announce the results. According to Lin Jue's evidence and the results of the investigation, the evidence in these six cases is conclusive, strong and credible, and the imperial court recognized the conclusion of these six cases, and commended all the personnel of the Yamen of the Kaifeng Prefecture's Criminal Division.

The news spread, and the reputation of the Kaifeng Prefecture Criminal Division was greatly enhanced. Someone in the Criminal Investigation Department revealed the process of Lord Lin solving the case, and it was even more talked about. In particular, Lord Lin's act of preparing a meat bun for the dog before he died was called a heart-warming move by dog lovers in the capital's ladies' circle. But they had forgotten that the dog was the victim of the experiment.
