"Brother Wang, let me tell you this, if there is a fire, the flame will consume a lot of oxygen, and the deceased will subconsciously replenish oxygen before death, and the mouth and nose will naturally inhale soot."

Lu Zhi took a few deep breaths with his nose in a row, "Just like me, inhale violently." ”

"Of course, this is the wrong thing to do, it will inhale toxic gases and hasten death, so it is safer to cover your mouth and nose with a wet towel."

Lu Zhi simply popularized science.

"And if a man is dead before the arson, his mouth and nose are clean." He pinched his nose, "Because dead people don't gasp." ”

"Now you understand? The case file contains a fabricated post-mortem report. Lu Zhi pointed to the autopsy report again and said, "It is clearly written on it that the deceased's mouth and nose are clean." ”

What does this mean? It means that they are dead before they walk through the water! ”

Lu Zhi struck his fists and palms together, making a final sound, "And the reason why the murderer set fire is to cover up the truth of the murder, and he is destroying the corpse!" ”

This is a piece of forensic common sense, which Lu Zhi saw when he watched the TV series before, he remembered that the whole drama was about the story of Song Ci, and the name of the TV series could not be remembered clearly, maybe it was "Clearing Grievances", or it could be "The Criminal Officer of the Great Song Dynasty".

Song Ci (1186-1249), known as Hui's father, Han nationality, was a native of Jianyang (now Nanping, Fujian), a fellow villager with Zhu Xi, a master of science, and his ancestral home was Nanhe County, Xingtai City, Hebei Province, and a descendant of Song Jing, Tang Dynasty.

Born in the thirteenth year of the Chunxi reign of Xiaozong of the Southern Song Dynasty (1186), a famous forensic scientist in the Southern Song Dynasty, it is generally believed that Song Ci founded the "forensic identification" in 1235 AD, so Song Ci is respected as the originator of forensic science in the world.

Headcatcher: "?? ”

Lu Zhi's statement does not seem to be false, it is reasonable and well-founded, but the headhunter is still suspicious.

Dayue's prison is still relatively backward, the autopsy is not systematic, and characters like Song Ci have not yet appeared.

Whether there is soot in this mouth and nose, and what it has to do with before and after death, the headcatcher does not know, and he has never heard anyone talk about it.

"You can tell these just by the soot from the mouth and nose of the deceased?" The Headcatcher retracted his thoughts and stared at Lu Zhi's eyes and asked.

Lu Zhi nodded, his eyes firm, "The living can lie, but the dead never will, they are more credible than the living." ”

The headcatcher stared at Lu Zhi's eyes for a long time, and finally nodded, "Okay, I believe you!" ”

Finally relented, with the support of the head catcher, things were much easier, Lu Zhi arched his hand, "Thank you, Brother Wang!" ”

"Since what you said is so sure, I'll find someone to verify it, I think it's okay, right?" The headcatcher himself believes that it is not good, if you want to use it as evidence, you still have to say it to a professional.

Lu Zhi gave his hand again, "That's nature. ”

This means that the case is already on the verge of review, and the next step is only to persuade the courtesy.

"Wait a minute, I'll call someone." After the headcatcher finished speaking, he hurried away.

In a short time, he brought four people back to the file room, and he was very fast.

Among these people, only one is known to Lu Zhi, Wang Er, the younger brother of the headcatcher, the reason why the headcatcher brought him over is probably to let him follow and learn.

As for the other three, one of them is a father and son, surnamed Song.

They are professionals, the old one is the Ling Shi (coroner) of Jingzhao Yin Yamen, and the younger one is still learning, they are both father and son, and master and apprentice.

This line of work is like this, it is generally passed from father to son, son to grandson, and even the position is the same, the father dies and the son succeeds, as if it is a "family business", the ancestral housekeeping skills.

In the end, the headcatcher didn't introduce him, and he himself said that he just came to take a look, and he didn't have to care about his existence.

Lu Zhi is so clever, even if he doesn't say who it is, he can guess seventy-seven-eighty-eight.

Isn't it Jing Zhaoyin, who is destined to have a short life, if you don't say it, I don't want to know it yet.

Although this official position is high, it is better not to get acquainted, so as not to be implicated in the future and get into trouble.

Lu Zhi thought clearly, didn't you say that you don't have to care about your existence, then I will pretend that I haven't seen you as a person.

What's it called? This is called pretending to be stupid and stunned to keep safe.

"Old Song Chengzuo, look......" Lu Zhi retold what he had just told the headcatcher king, and Old Song Zhuozuo nodded again and again, feeling reasonable.

The headcatcher wanted to speak and stopped several times, but in fact, it was not quite the same as Ling Shi, and calling Song Lingshi Song Ling Shi Song was contemptuous and belittling.

Ling Shi belongs to the official named in the imperial court, although there is no money, but there are three or four taels of "food and silver" (equivalent to food supplement) every year, and the work generally refers to those who help carry the corpse, they are doing dirty work, and their status is very different.

Of course, if you insist on calling it a fool, it's no problem, but if you are afraid that you will meet someone with a bad temper, it will offend people.

"Hey, it sounds reasonable, but it's still lacking in evidence." Lao Song is also the same as the headhunter, probably believing it, but he can't be 100% sure of the truth.

"Evidence?" Lu Zhi's eyes narrowed slightly, "Well, there is, in fact, this is not a difficult matter, as long as you look through a few more files, you should be able to gain something." ”

A Jing Zhaoyin, who did not want to disclose his name, made a look, and the head-catcher quickly turned out some files that went away.

"I'll teach you another method, which is called induction." Lu Zhi took the files, opened them one by one, and found the autopsy reports attached to them.

"Let's put these autopsy reports together first......"

"Observe, are the vast majority of them recording soot from their mouths and noses?"

As the main person in charge, Lao Song looked at it very carefully, coupled with the statistical chart drawn by Lu Zhi, the result was naturally clear at a glance, not to mention the truth, it was also eight or nine without leaving ten.

"Yes, in this way, what Lu Gongzi said is true." Old Song stood up and bowed his hand respectfully at Lu Zhi, "The old man has been taught." ”

Lu Zhi also hurriedly got up and saluted, "Don't dare, I actually know a lot about this, I just know some inductions." ”

"Summing it up!" Old Song and Jing Zhaoyin, who was unwilling to reveal his name, sighed at the same time.

Lu Zhi nodded, and didn't care about a certain court member who was "incognito", "As long as the old Song Dynasty masters this method, he will definitely be able to write a "Record of Clearing Grievances" that is enough to clear the world's grievances!" ”

"When the time comes, everyone in the world will learn the "Record of Clearing Grievances", and they will definitely be able to show the snow for those who have been wronged!" Lu Zhi showed a look of longing, "At that time, I will definitely clear the sea and the river, and the people will live and work in peace and contentment." ”

"Clearing?" Old Song Cheng finished his work and laughed, "I can't do it anymore, I'm old, but my kid is quite talented, and it is possible to do it." ”

Xiao Song waved his hand again and again when he heard this, "I can't do it, I can't do it......"

Lu Zhi shook his head, "You haven't tried it, how do you know it doesn't work?" Brother Song, you have to believe in yourself. ”

Xiao Song opened his mouth, stomped his feet, and nodded fiercely.
