In fact, the blood book is only a part, and at the scene of the crime, that is, the inn where Bangyan lived, blood characters were written on three walls, and the scene was very terrifying.

After being adjusted according to the content of the blood letter, the general content is that there was fraud in this scientific expedition, and he was an accomplice and a victim in it.

At the scene of the crime, some evidence left by Liu Jin was also left, which was presented to Wei Guojun's desk as soon as possible.

Liu Jin is a real son of a poor family, and he has no background at home, and he speaks out in a remote and poor mountain village in Yangcheng.

Because he has been smart and talented since he was a child, the people in the village are willing to sponsor him to study and take scientific examinations, and he does live up to the expectations of the whole village, from childhood to child, except for the examination of Xiucai because of the discomfort of the environment and fell ill and rude once, and then it was a time to pass the exam, so that the villagers have deeper hopes for him.

This time he came to the imperial city for the palace test, and all the entanglements should be made up by the people in the village, and he may promise to return to his hometown.

It's just that he didn't expect that he would get into trouble because he participated in a poetry tea party.

Because of his outstanding literary talent, he was appreciated by Mu Shaochen, and he was invited to talk about poetry and strategy several times.

Because Mu Wuye was also born in Tanhua and had qualifications in the court, he was also pleasantly surprised to be able to ask the fifth master for advice, so he did not refuse, and even sometimes the fifth master would give some questions in the name of guidance for them to take the test together.

Liu Jin didn't think much about it, and was even more grateful to the fifth master and Mu Shaochen, thinking only that if he could join the priesthood in the future, he would find an opportunity to repay him.

It wasn't until the palace exam began, when he saw the familiar exam questions, that he was confused, and then he realized that something was wrong.

If it's just a coincidence, but if you hit three questions in a row, how can this be a coincidence?

After the palace test, he panicked, and wanted to go to Mu Shaochen several times to ask, but he couldn't find the door, and basically closed the door.

Later, when asked for advice in the final hall, Wei Guojun asked the examiner to read out one of Mu Shaochen's strategies for other candidates to study, and he was shocked to find that that policy was also one of the articles he used to give to the fifth master when he took the school examination.

At this time, he really realized that he might have accidentally stepped into a trap, and he wanted to point it out in the palace, but he was timid, after all, there were all the people of the village behind him, and he didn't dare to gamble with the lives of his relatives and villagers.

Later, Mu Shaochen was handpicked as the champion, and he became a role model, so Mu Shaochen secretly sent someone to send gold and silver, so that he would keep his mouth shut in the future, and even threaten him with his future promotion.

He was locked in his room alone and struggled for two days, until he received the notice of the Qionglin Banquet, he finally couldn't clear his conscience, and finally decided to expose the case in such a desperate way, and begged the king to hold the lives of the villagers.

On the same day, the case was directly handled by Dali Temple and the Criminal Department.

Wei Jiuli invited himself to enter the Dali Temple, but was rejected by Wei Guojun, but also let him be temporarily grounded in the Li Wang's mansion.

Several other examiners were also grounded, but this matter has not been publicized for the time being, but the movement of the investigation of the case in Dali Temple is not small, and after some people from the prince's party learned the news, they immediately convened their staff for consultation.

However, due to the current anger of Wei Guojun, they did not dare to add fuel to the fire without authorization for the time being, so as not to be angered.

When Bai Tang learned about this, Wei Jiuli had already been grounded.

During this time, she lived in the county lord's mansion, which was convenient for the pharmacy and the Yude Hall to run.

Therefore, when she entered the palace and met Wei Guojun smoothly, it was already the afternoon of the next day.

She did not plead or plead for Wei Jiuli, but invited herself to participate in the case.

Originally, she was still Wei Jiuli's fiancée and could not participate, but this incident happened strangely.

Rongguo Mansion didn't say it, it was extremely strange when the test questions were leaked, because the test questions were handed over by him three days before the exam.

But not many people know about this matter, so it doesn't match the time Liu Jin said.

But what Liu Jin said seems to be reasonable, but some of the things in it are also very vague, so it is impossible to absolutely reject his pleadings here.

But because of this, Wei Guojun sniffed out the unusualness behind this matter after his anger, otherwise most of the people in this matter would not have been grounded, but would have been tried directly in Dali Temple.

So after some consideration, Wei Guojun granted Bai Tang's request.

After all, Bai Tang's medical skills are there, and with the last incident of Mu Shaochen as an example, I can't say that I can find some clues that others can't see.

With Wei Guojun's permission, Bai Tang also breathed a sigh of relief.

The other party allowed him to participate, which showed that he still had at least some trust in Wei Jiuli.

Dali Temple and the Criminal Department received a notice, although they also felt that Bai Tang's identity seemed a little inappropriate to participate in the case, but now they have no extra clues, maybe Bai Tang's medical skills can really find clues, plus Wei Guojun's will, so they also let her go to investigate.

On the side of Dali Temple, after a post-mortem examination, Liu Jin had no other fatal injuries except for multiple knife wounds on his hands and arms, and the real cause of death was suffocation, which was caused by the last hanging beam.

As for the several wounds on his hands, it is estimated that he was injured by bloodletting and writing a blood book, which means that he did commit suicide, ruling out the possibility of his murder.

Bai Tang first inspected Liu Jin's body, and the result was indeed as he said, whether it was the cause of death or the injuries of the other party, it was to exclude other factors.

But with the system, she could get clues from other places, such as the blood stains on his clothes.

She asked about the situation in the room, went to see it for herself, and then came to the first suspicion.

"You mean that this blood is not human blood, but the blood of other animals? Is there any evidence for this? ”

Dali Siqing and the waiter of the criminal department looked at each other, no wonder they were suspicious, after all, they did not find the corpses of other animals at the scene, and they also asked the innkeeper, saying that this person has not come out much in the past two days, and he has not asked for anything.

Their first thought was whether Bai Tang wanted to exonerate King Li from his guilt before he deliberately said this.

Bai Tang can't be said to be scanned by the system, but can only say, "There is a limit to the amount of blood flowing out of the human body." ”

"An ordinary wound does not cause rapid bleeding, and there are two ...... on a person's wrist The pulse, once spaced, will bleed profusely, but the speed of this bleeding is related to the person's situation and environment. ”

"The bleeding is fastest at noon, the slowest at night, the bleeding is fast in summer, and the bleeding is slow in winter, and if a person has strenuous exercise, the bleeding will be fast, but Liu Jin does not meet these three, he is in a slow blood environment."

The two looked at each other again, then frowned and said, "This is also reasonable, because the blood flows slowly to have time to write the blood book, if it is too fast, it will not die soon." ”

Bai Tang said, "This is unreasonable, these things are only known to most doctors, why Liu Jin is so clear, but his clarity is not completely clear, although slow blood has time to prepare, but slow blood flow will cause more burden on the body than fast blood, such as weakness and body temperature imbalance soon, coupled with the low temperature now, it is likely to cause blood to coagulate quickly and limbs to stiff." ”

"But the two of you look at it, the blood book may not be able to be carefully examined because of the cloth, but the blood book on the wall is sonorous and powerful, which is indeed a good interpretation of the author's anger, but the blood book on the wall needs a lot of blood, according to the human body's 2000cc blood loss, it will be in a coma and know death, the blood required on these three walls is at least close, not to mention the blood flowing on the ground, at this time, how can the other party still have the strength to wave ink?"

The two of them listened to the 2000cc and didn't understand a little, but they also somewhat understood the meaning, and they immediately frowned.

Bai Tang continued, "What's more, the other party committed suicide not because of excessive blood loss, but because of the real cause of death. After losing so much blood, the other party still had the strength to climb onto the table, and then hung the beam, according to the condition of the body, at this time, the other party should have suffered from excessive blood loss and brain hypoxia, heart arrest and other symptoms, the mildest is also a deep coma. Therefore, if he kills is ruled out, then there is also a possibility that the blood at the scene is not all the blood of the deceased Liu Jin, as for the blood of humans or other animals, it will need to be fine. ”

"This, the county lord may be sure that these states are true?" The waiter of the criminal department hesitated for a moment, and asked uncertainly, after all, they understood the general meaning of what Bai Tang said, but they still didn't understand some terms.

"The two adults can ask the imperial doctor to verify, but it is better to investigate the inn first, after all, according to the guy, the other party has been indoors, and he has not asked for anything during the period, and no one has come, but this blood is also fresh, at least no more than two days out of the body, so if the blood is not his own, where does it come from, it is impossible to appear out of thin air, if it is really his own blood, how to explain those symptoms, unless he is not an ordinary person."

The two of them pondered for a while, and then they were sent separately, and while ordering people to re-interrogate the people in the inn separately, they first wrote down what Bai Tang said as a recital.

Bai Tang passed through the system, but he was able to determine that the blood on the wall was chicken blood.

The clotting rate of chicken blood is faster than that of humans, unless it is specially treated, but there are no other components in the blood, so this blood must be out of the body not long after writing, and it is still fresh.

Then the scene of blood collection can only be in the inn.

Human blood is different, and so is animal blood.

Bai Tang took people to check the broiler chickens in the inn, but although the inn also has its own chickens, because of the recent large number of customers, most of the chickens are temporarily purchased from outside.

The blood of the chickens does not match the others, which means that the chickens were either brought in and killed on the same day, or the person who provided the blood brought it himself.

Those who can bring their own chickens are either the people in the inn or the people who bring the chickens.

Through systematic scanning, Bai Tang also found trace traces of blood from several places outside Liu Jin's house.

Liu Jin's house is on the first floor and next to the kitchen backyard, which is the cheapest room, and the blood stains are scanned from the corner of the window, although it has been processed, the human eye cannot see it, and there is no modern high-tech detection, but the system has swept it out.

In other words, the other party was likely to stand here at that time and kill the chicken, and then take blood and hand it to Liu Jin in the room.

These clues were reported to Dali Siqing, and the other party did not ask her how she knew or whether she could be sure, after all, he did not understand medical skills, and he did not understand whether the doctor could do it like her.

And the clues provided by Bai Tang do have a great effect, at least to speed up the investigation.

The innkeeper also said that these days because of the imperial examination, the inn is full almost every day, and as a noisy backyard and kitchen, it is impossible for no one to find out that someone is stealing chickens and not suspecting, so there is a possibility.

The person who kills the chickens may be the cook in charge of killing the chickens in the back kitchen, or the guy who does these things on a daily basis.

As for where the chickens go, they are naturally cooked.

Therefore, these individuals are immediately retried.

Sure enough, it didn't take long for someone to be found.

It was a kitchen helper in the inn, but he also took people's money to do things for others.

He said that someone had given him a tael of silver and asked him to quietly take fresh chicken blood in the evening and give it to a guest in the local shop.

This guest because of the list of eyes, is also a good thing for the inn, so no one does not know him, just because of his withdrawn personality, the shopkeeper in him after he won the list of eyes originally wanted to change him to the Tianzi room for free but was angrily scolded by him and refused, and then the shopkeeper did not dare to touch his brows, only ordered if the one had any orders to be satisfied.

The man just thought it was the one who wanted to do something with this, and he had always heard that many literati sometimes used animal blood as a pigment in their paintings, so he didn't doubt it.

However, the other party said that it should not be seen when it was sent, and it must be fresh and able to be written.

So he drove out and brought the chickens over, personally killed them and put them on plates, and then put them on the windowsill, and he didn't see the strange-tempered leader, for which he regretted a lot.

After that, he took the chicken back to the kitchen and neatly packed it up for the chef to cook, and when someone asked him, he said that the movement of the chicken when he passed by there made the adult unhappy, so he killed the chicken directly in fear, saving the adult from making noise, and the others did not suspect it.

But he never expected such a bloody case.

Here's another clue.

Liu Jin came to the imperial city alone, and did not bring any scholars or servants, because he wanted to reduce the expenses on the road, and no villagers sent him along.

So the guy who gave the guy money to buy blood was crucial.

Under pressure, the man tried to recall the appearance of the person to describe it, and through the artist's memory, a portrait slowly appeared.

The man adjusted to the portrait for a few more moments, and finally appeared the closest face to the person he had seen.

However, the face of the person in the painting is ordinary, and according to the description of the guy, the clothes are also ordinary coarse cloth short clothes, but it is not ruled out that they are deliberately disguised.

After asking for instructions, Dali Temple immediately pasted this portrait on the emperor's list for wanting.

And the next day, the man was found, but it was the body of the other party.

This person's name is Chen Ercai, he was born in an ordinary family, his identity and resume are not abnormal, and his death is also suicide, but his suicide is different from Liu Jin.

Chen Ercai died of a stroke, and it is said that he died of an overdose of rejuvenating drugs while having sex with the widow next door.

After the examination of Qi Zuo and Bai Tang, it is true that this person died because of an overdose of rejuvenating drugs, because he was too excited and his heart was hypoxic when he replied to the high tide, and he was not treated immediately.

But is it so coincidental that they offered a reward for each other, and the man died the next day. NPC in Ancient Times: Doctor Sees Love, Depends on You
