Look at the appearance of the dog's egg, the skin is not as pale as the dead, and the demeanor is also serene and peaceful (). Asha didn't believe that this was so cute today, and his face was soft, and she suddenly grabbed the position of his lower back spine, and a force passed over.

Frustrated to find that it was completely mud cows entering the sea, Asha was convinced that the dog had indeed lost his life.

"What made him die so strangely?" Asha held back his anger and thought about everything he knew in his heart: Urging the heart? Xuan yīn means? Half a step with a smile? It doesn't seem to be!

Asha is in the south all the year round, so it's not surprising that I don't know, but in fact, this is a common disaster in the cold regions of the north, which is very easy to cause when burning fires to warm up in winter.

"Carbon monoxide poisoning" Qin Lin chuckled his chin, and quickly realized the confusion of dragging the oil bottle, so he changed his words: "Or coal poison." ”

Carbon monoxide poisoning, also commonly known as gas poisoning in later generations.

Combustible materials such as firewood and coal are combusted, mainly by combining carbon elements with oxygen in the air to produce non-toxic carbon dioxide.

However, when doors and windows are closed, air circulation is poor, and oxygen supply is insufficient, insufficient combustion will produce highly toxic carbon monoxide.

Carbon monoxide is an odorless gas that is not easily detected. The binding capacity of hemoglobin to carbon monoxide in the blood is more than 200 times stronger than that of oxygen, and the separation of hemoglobin from oxygen is very slow. Therefore, once a person inhales carbon monoxide, oxygen loses the opportunity to bind to hemoglobin, so that tissue cells cannot get enough oxygen from the blood, resulting in poisoning.

In the early stage of poisoning, the hemoglobin bound to carbon monoxide in the human blood is 10% to 20%, at this time, headache, dizziness, palpitations, nausea, vomiting, weakness of limbs, and even temporary fainting, the general consciousness is still quite clear, inhaling fresh air, and the symptoms disappear quickly after getting out of the poisoned environment, and most of them do not leave sequelae.

However, if you do not escape from the poisoned environment in time, and the hemoglobin occupied by carbon monoxide reaches 30 or 40 percent, you will collapse or faint, and then you will completely lose the ability to save yourself, and if you are not discovered in time, you will not escape the clutches of the invisible god of death ().

In the case of Zhou Laohan and Goudan, it is found that if you inhale too much carbon monoxide too late, more than half of the hemoglobin loses its ability to supply oxygen, and the patient will be deeply dizzy, lose various physiological reflexes, drop blood pressure, shortness of breath, and unconsciously die in sleep.

Qin Lin only glanced at it, and basically determined the cause of death of the two of them, which was actually very simple, it was the weird red sè on their skin.

After carbon monoxide is combined with hemoglobin in the blood, the carbonyl hemoglobin produced is cherry red, and the capillaries of the mouth chún are quite abundant, and the mucous membrane of the mouth is very thin, and the blood containing carbonyl hemoglobin coagulates after death, and what you can see through the mucous membrane of the mouth is bright cherry red.

On the other hand, the skin on the cheeks and other areas are thinner and the capillaries are richer, and the skin will also appear red with different shades.

This is evidence for the determination of carbon monoxide poisoning.

Qin Lin explained these words to her in a way that Asha could understand.

"I see, I see!" Asha leaned down, lowered his head and looked into the kang hole, simply half of his body went in, and soon took out a mass of rags stained with soot: "Uncle, is this thing blocking the chimney, and the dog and his grandfather were smoked to death?" ”

Qin Lin nodded and handed Asha a brother's gloves for her to put on, just now he was also about to take a hook to dig out the kang hole, but he didn't expect Asha's slender body to be able to get in, which saved him trouble.

Holding the cloth and observing it carefully, Qin Lin was a little disappointed, and walked outside to ask Lu Yuanzhi to take out the finger brush and gold and silver powder from the forensic tool kit, and carefully brush it on the rag.

After a long time, he let out a long sigh and put down the finger brush, this piece of cloth is too rough, and it is impossible to get the finger brush with the current technical means, "In later generations, there is a use of fumigation to take the index on the rough texture, but that requires special instruments and chemical drugs."

Wang Xiangqian was stopped at the door by Niu Dali just now, so he stood on tiptoe and looked inside, although he was dissatisfied with Qin Lin, seeing that he was concentrating on his work without distractions, he also knew that he must have a deep meaning in doing so, so he stayed by the side ().

When Qin Lin came out and put down the rag in disappointment, he arched his hand and asked, "I don't know if General Qin has found out the problem?" Although this case involves the White Lotus Cult, after all, it happened in the jurisdiction of the official, and it was the people under the rule of the official who died, so do you see if it is ......"

Qin Lin didn't stop them this time, allowing them to send two people in, but they weren't allowed to touch anything.

Wang Xiangqian thought about it for a while, and walked in with an old servant, and after a while, the old servant shouted: "Hey, this is charcoal poisoning."

As mentioned in the "Record of Clearing Grievances", those who are poisoned by coal and leak fire and filthy in the pit are fumigated and kill themselves unconsciously, and their corpses are soft and unharmed, similar to those who cannot recover from nightmares. ”

Hearing this, Wang Xiangqian's face turned a little pale, and when he came out, he bowed deeply to Qin Lin: ...... Dare to ask this rag, but it was taken out of the fire kang flue? ”

Qin Lin didn't raise his head: "Yes, and it's the lower end of the flue, not far from the kang cave." ”

Wang Xiangqian's smile immediately became a little bitter, if the top of the chimney was blocked, "There is also a possibility of death from murder, the lower end of the chimney is blocked, of course, the people in the house committed suicide."

As a parent official, the people under his rule were forced to die because of the demand for taxes, and reported to the top, a sentence, "cruelty and harm to the people" test language can not run away, even if Wang Xiangqian's family is a famous family in Shandong Shilin, this time I am afraid that I will make a mess, at least the position of Jizhou Zhizhou, most of them can not be kept.

What's more, he also offended General Wei Qin, who is known as "repaying grievances with virtue"?

Qin Lin ignored Wang Xiangqian and looked at the courtyard by himself.

The footprints on the ground, the fingers on the table, the door and the kang, he didn't take them at all, because there was no concept of protecting the scene at this time, so he asked Zhou Yude on the way here, and many villagers came in in the morning to try to rescue, and I don't know how many people have stepped on it, even if they find the footprints and fingers, it is meaningless ().

"Lu Yuanzhi!"

Qin Lin shouted, and Lu Fatzi came up with a raw cowhide bag, knowing that his business had arrived again, but this time it was Zhou Laohan and Goudan, who had met twice, and the feeling in his heart was very different from before.

"You go in to check the time of death, check if you have been tied up or drugged, if you are ordered, there will also be injuries on the xué position" Unlike in the past, Lu Yuanzhi played by himself and made up for it later, Qin Lin instructed in detail.

Even after finishing speaking, Lu Yuanzhi walked in, and Qin Lin stopped him again when he remembered it: "Cut the throat and see, if it is indeed inhaled carbon poison and died before death, there should be a fine black dust in the trachea." ”

Lu Yuanzhi nodded, he could see that Qin Lin attached great importance to this case, and even he himself was not bent on avenging Zhou Laohan and the dogs?

Could there be something else? The old man also walked out of the room, and when he heard this, he felt very strange, and couldn't help but ask Qin Lin Jiyin.

"The skin is rosy red, the body and the soft god are dying peacefully, it is indeed a sign of carbon poison, but if you are put in this room full of carbon poison immediately after being killed, the carbon poison will still enter the blood through the skin and dry membrane, so the skin of the corpse will still show cherry red sè" Qin Lin said and put his hand down to everything, "Therefore, this official must rule out all possibilities!" ”

The old man was stunned when he heard it, he really didn't expect that a carbon poison would be so exquisite, if it weren't for Qin Linguan's worship of the commander of the Sanpin Jinyi, he would really want to learn from the teacher.

While Lu Yuanzhi was examining the corpse in detail, Qin Lin began to interrogate the villagers who found the corpse and knew about Zhou Laohan's recent situation.

The person who found the body was a neighbor Zhou Wang, he was a simple and honest peasant man, he was very scared when he saw Qin Lin, a big official, and comforted him for a while before stammering: "I, I saw that Zhou Lao Han's farewell door was still closed in the morning, you know, how early Lao Han had to get up to make breakfast for his son, see how late he hasn't gotten up, I feel bad in my heart."

I shouted and didn't hear anyone, so I quickly ran here to knock on the door, there was no sound inside, I couldn't say it well, poke the window paper and see, don't lie on the kang, the house exudes a smell of firewood and charcoal.

Oops! I quickly opened my voice and called someone to knock the door open......"

There were several other villagers who slammed the door open, and they all proved that the door was tightly closed from the inside.

Qin Lin nodded, he had also checked the door latch just now, it was a relatively thick wood, the fresh fracture marks were very natural, and the indentations formed on the door frame during the impact were also completely phytologically distinctive, and there was nothing suspicious.

"And what about this mass of rags?" Qin Lin pointed to the rag, "Which of you knows if it's Zhou Jiaran?" ”

Zhou Wang looked at it carefully, "That's right, I saw Zhou Laohan wiping the table with it." ”

Bird's, this is the ghost encountered, is it a closed room murder case?

Although Qin Lin couldn't be called like electricity, his observation was also very meticulous, and he found that the two windows of this room were nailed from the inside, and they couldn't open the cold Jizhou countryside at all, which is very common in winter.

The door is bolted from the inside, and the broken latch and the marks on the door frame are very natural.

It's normal, there is no suspicion, and it is impossible for Zhou Wang and so many villagers to join forces to give false testimony.

Qin Lin grabbed the wooden door and shook it, and found that if he pushed it inside, there was still a gap underneath, and at most a fist was stuffed into it, but it was absolutely impossible for anyone to get through.

Thinking about it for a while, Qin Lin asked the villagers if they knew the cause of Zhou Laohan's death, and the villagers said it babblingly
