Under normal room temperature conditions, the rate of cooling of a human corpse drops by an average of about one degree Celsius per hour for the first ten hours, and the decline slows down to twenty-four hours, to the same temperature as the surrounding environment.

Although it was winter, the temperature in this room was above freezing, and there was no wind, so the corpse would be cold at a slightly faster rate, but it would not exceed two degrees Celsius per hour.

Judging from the fact that the corpse spots and zombies on Lao Xiucai's body have just appeared, the time of Lao Xiucai's death is about two hours, so that the temperature of the corpse will not drop by more than four degrees Celsius due to the corpse cold, that is to say, if the body temperature of the corpse of Lao Xiucai is about thirty-two degrees now, it is in line with the normal corpse cold speed.

Yang Qiuchi found that Lao Xiucai's body temperature was only slightly lower than that of ordinary people, but it obviously did not reach a fatal body temperature below 25 degrees, and the test results were consistent with normal corpse cold.

When a person's body temperature drops to about 32 degrees Celsius, consciousness will be impaired, exercise ability will be low, and even hallucinations will occur, but it is impossible to freeze to death, therefore, judging from Lao Xiucai's current body temperature of about 32 degrees, the possibility of freezing to death can be completely ruled out.

It's just that Yang Qiuchi can't discuss with the people of the Ming Dynasty such a modern question as how many degrees of human body temperature is, so he can only say it in such a general way.

Jia Hanlin asked, "Then how did this Lu Xueru die?" ”

Yang Qiuchi bowed down and replied: "Wansheng carefully examined the whole body of the deceased and found no obvious injuries, which can rule out external injuries and death." Examination of the body bones of the deceased found no fractures, which can basically rule out death from internal injuries. Yang Qiuchi pointed to the vomit on the side of Lu Xueru's mouth: "According to this vomit, the late life suspects that this Lu Xueru died suddenly due to the sudden outbreak of his own hidden disease, of course, it is also possible that he died of sudden death caused by poisoning." ”

Na Zuo had been watching coldly from the sidelines, and then sneered: "Poisoning? Joke, I tested the vomit with a silver needle, and it didn't turn black, how could it be poisoning? It's a joke! ”

There are too many poisons that can cause poisoning, such as corrosive drugs, metal poisons, and dysfunction poisons, such as strong alkalis, inorganic compounds, sedatives, anesthetics, cyanide, nitric oxide, and even snakes and scorpions or plants such as Chuanwu.

The silver needle can only detect the poison containing sulfur or sulfide to turn black, and some poisons do not contain sulfur, such as mushrooms, nitrites, pesticides, cyanide, etc., and the silver needle will not turn black when it comes into contact with them. Therefore, the fact that the silver needle does not turn black does not mean that it is not poisoned.

Yang Qiuchi was very considerate of the difficulty of a grievance, did not laugh at him, and said sincerely: "What you are talking about is arsenic poisoning, which can be detected with a silver needle, but there are other reasons for poisoning, not every poison can make a silver needle black, such as a lot of poisonous mushrooms, which can be probed with a silver needle, will not turn black, but can poison people." ”

Seeing Yang Qiuchi's sincere attitude, Na Yanzuo was also a little embarrassed, and asked: "You said that it may have been poisoned, and it is not arsenic, so what is it?" ”

To determine what the cause of poisoning is, it is necessary to conduct an autopsy, extract the stomach and stomach contents, and conduct poison testing, of course, it is not possible to make a conclusion about whether it is poisoned based on this result alone, it is necessary to conduct a comprehensive autopsy and observe the pathological changes of various organs, so as to discover the potential surname disease that the deceased suffered from before his death, distinguish whether it is sudden death or poisoning caused by disease, and extract liver, kidney, brain and other tissues and blood, urine, bile and other samples for poison testing, comprehensive analysis, in order to determine which cause of poisoning.

If it had been a few days ago, Yang Qiuchi would probably have rashly proposed an autopsy, but after the last time Song Qing almost lost his head, Yang Qiuchi was much calmer. Through this incident, he understood a very simple truth - if you want to protect others, you must first protect yourself. Imagine, if he was beheaded because he released Song Qing privately, Song Qing would not be able to escape.

However, now he is facing. It is not only a matter of thinking twice, but more importantly, it is necessary to make a radical change in the way we think about modern society that has been formed in our heads, and this is the most difficult thing.

In the case at hand, the death of an unknown cause, the forensic doctor now has to perform an autopsy 100 percent, and only by performing an autopsy can we accurately determine whether it is a disease or poisoning, and what kind of poison is there. But in the Ming Dynasty, let alone dissection, even if the dissection was proposed, I am afraid it would be regarded as a rebellion against feudal etiquette, and the consequences can be imagined.

Therefore, Yang Qiuchi did not recklessly propose an autopsy, he wanted to follow the path of the ancients, judge through the clues and comprehensive situation, and find out the real cause of death of the old Xiucai Lu Xueru.

This case happened in the Gongyuan where the imperial examination was being held, and there were people all around, but no one heard the sound of Lu Xueru calling for help or struggling, so it can be judged that if it is poisoned, then this poison is likely to be a neurological poison that can cause dysfunction of the central or cardiac nervous system, causing a sudden attack of poisoning of the heart and cerebrovascular lesions, resulting in sudden death.

Only in this case, Lu Xueru had no time to call or was unable to call. Of course, it cannot be ruled out that Lu Xueru himself suffered from this kind of disease, and the possibility of sudden onset leading to sudden death cannot be ruled out.

Regarding the question of resentment, Yang Qiuchi shook his head and said: "At present, I don't know how he died, I just suspect that if we want to thoroughly investigate the cause of Lu Xueru's death and determine whether he killed him, I am afraid that it will take an in-depth investigation to find out the clues." ”

Although Yang Qiuchi has not yet found out the real cause of Lu Xueru's death, he has clearly ruled out freezing to death. affirmed this, which made Jia Hanlin very happy, if so, then he had no responsibility.

Yang Qiuchi didn't expect that he had inadvertently done the examiner a favor. However, Yang Qiuchi is now more than less, anyway, this matter doesn't care about his own business, besides, whether he killed it or not, he didn't dare to be sure before the autopsy. I'm about to leave.

Jia Hanlin was smiling and thinking, he couldn't see that the young man in front of him was quite capable, he was a talent, although he got out of the way, and the case was handed over to Ying Tianfu, he had nothing to do, but Ying Tianfu Gu Fu Yin had a good relationship with him, if this case could not be solved, this Fu Yin would also have a headache, after all, this was a problem in the emperor's Enke exam, and it was difficult to explain if he couldn't find out. If Yang Qiuchi had helped, the hope of solving the case would be much greater.

Jia Hanlin saw that Yang Qiuchi was about to slip away, and hurriedly said: "Yang Gongzi, now that you have finished the imperial examination, you are waiting for the list to be released, and the surname Suo will help you find out this case clearly." Lord Yin Gu of Tianfu Mansion is an old friend of this official, and I will introduce you to him when he comes in a while, if there is a son to help, he will be sure to solve this case, and he will be very happy. What does Childe think? ”

In fact, Yang Qiuchi is also a warm-hearted person, he is a sure person, although there is no need to please this examiner, but seeing that this examiner speaks kindly, he can't wipe his face.

Besides, he was also very curious about whether this case was killed by him. There is nothing to do left and right, and it is okay to take care of this idle matter, anyway, you have to wait for the list in Yingtianfu to go back for the New Year, and then take Mrs. Bai and her mother to take office. It's going to be a while. He nodded in agreement.

Jia Hanlin was very happy, and asked Yu Zuo to lock this room and guard it here, and sent someone to inform Ying Tianfu Mansion Yin immediately. Jia Hanlin took Yang Qiuchi and the general judgment of the Heavenly Mansion to wait in the rest hall of the Gongyuan Courtyard. When the talents saw Yang Qiuchi and the examiner leaving together, they were amazed and jealous.

After a while, Lord Yin Gu of Tianfu Mansion came, and after Jia Hanlin introduced him, Gu Mansion Yin said that he had heard of Yang Qiuchi for a long time, and it turned out that Governor Zhou of Ningguo Mansion had a close relationship with Gu Mansion Yin, and Governor Zhou had told Gu Mansion Yin that Yang Qiuchi had helped solve the big case.

When Gu Fuyin heard that Yang Qiuchi was willing to help find out the case of Lao Xiucai's death in the Gongyuan, he was immediately overjoyed, and asked the general judge who had just brought him to assist Yang Qiuchi in investigating the case. This general judge's name is Hu Jiang, he has a horse face, and he speaks kindly.

Yang Qiuchi didn't like this kind of officialdom, and after talking for a while, he resigned with Hu Jiang and began to investigate the case. Yang Qiuchi took Hu Jiang to the gate of the Gongyuan to say hello to Song Yun'er, so as not to worry her.

Hu Jiang saw that Yang Qiuchi actually brought fifteen follower guards, and all of them had big shoulders and round waists, and their faces were cross-faced, they didn't look like good people at first glance, they were a little envious and a little hairy, so they didn't dare to ask more.

As soon as Song Yun'er heard that she was going to investigate the case, she liked the excitement the most, and immediately shouted to go together. Hu Jiang heard Yang Qiuchi introduce Song Yun'er as his cousin and the daughter of the new Tongzhi Song of Ning Guofu, of course he had no objections.

Hu Jiang asked Yang Qiuchi: "Young Master Yang, what should we do?" ”

Yang Qiuchi said: "The vomit is still there, right?" ”

At the mention of this vomit, Hu Jiang frowned and nodded.

"I want to re-examine that mess of vomit." Yang Qiuchi said flatly, since he couldn't dissect it, he could only hope to find something out of this vomit.

Originally, Yang Qiuchi's mention of that stall of vomit had already made Hu Jiang uncomfortable, and now he said that he was going to check it, Hu Jiang couldn't help but turn his stomach for a while when he thought of stirring that stall of vomit.

As soon as Yang Qiuchi saw his expression, he knew what was going on, and secretly smiled bitterly, what can be done, forensic medicine is like this, what he used to be in contact with all day long was those [***] dead corpses, all kinds of vomit, excrement, and all kinds of messy body fluids, looking for clues from this, it was dirty and tired, so no woman wanted to be his girlfriend.

However, I didn't expect to come to the Ming Dynasty, which is quite popular, think about the reason, it may be that the women of the Ming Dynasty pay attention to three obedience and four virtues, and there is no problem of looking down on men's professions. As long as you have money and ability, you don't have to worry about no women.

From this point alone, Yang Qiuchi really can't hate this evil old society.

Yang Qiuchi walked towards the Gong Courtyard, Song Yun'er followed Yang Qiuchi closely, and Hu Jiang also followed with a frown.

On the way, Yang Qiuchi and Song Yun'er briefly told what happened, and when Song Yun'er heard that there was another murder, this time it happened in the Gongyuan, and she was excited and a little surprised.

The three of them came to the room, and there were a few inspectors who watched here, and the man in charge of guarding the corpse opened the door, and the corpse was covered with the robe that had just been taken off. Yang Qiuchi entered the house and squatted down, picked up the brush on the ground, turned it upside down and wiped the end of the pen clean, and began to turn over the vomit.

At this moment, Hu Jiang and the examiners were so disgusted that they turned their faces, and some even hid far away.

Song Yun'er also frowned, but she didn't dodge, she thought that this was also a good opportunity to test whether she could be as brave as a man. Even so, I still felt a stomach turn.

Yang Qiuchi didn't think it at all, he was used to it, compared to the strange smell and stench of those high [***] corpses, this was simply too pediatric.

In the vomit, some undigested minced pickles were found, and in addition, some small green fragments caught Yang Qiuchi's attention. But he couldn't see what they were. So he simply lay on the ground, put his nose on the vomit to observe, and after looking at it for a long time, he still couldn't tell what these small fragments were.

It seems that this pile of vomit can only be extracted first and studied later. Yang Qiuchi asked the inspectors to find a clean hard white paper, and carefully shoveled the vomit into the white paper, wrapped it, and put it into a paper bag.

After seeing Yang Qiuchi clean up, Hu Tong asked, "Young Master Yang, what should we do next?" ”

Yang Qiuchi said: "Go to Lu Xueru's residence in Ying Tianfu to check and see if there is anything that can cause him to be poisoned." Hu Jiang agreed.

After checking the address in Beijing registered in Lu Xueru's examination register, he lived in a small inn called "Dengke Inn" in Yingtianfu.

There are too many small inns in Yingtianfu, and Hu Jiang and they don't know where this "Dengke Inn" is. At that time, there was no such perfect industrial and commercial registration system as it is now, so I had to ask around.

Hu Jiang brought a few officials, Yang Qiuchi took Song Yun'er and the fifteen guards, a group of people asked around, like headless flies to listen everywhere, and it took a lot of effort to find this "Dengke Inn" in a remote alley in Yingtianfu.

The shopkeeper is an ugly old woman, the ancient people are afraid of seeing the official, the female shopkeeper saw the official coming, a little flustered, but can not dodge, only to accompany the smile of the courtesy.
