Just as Uncle Guang and King Xian were talking, Jiang Hao, King Xian's right-hand man, asked for instructions outside the door:

"The king, my subordinate Jiang Hao asks to see you."

King Xian frowned and said:

"Come in."

"No."

Jiang Hao hurriedly entered the house, his chest and back were already soaked, and seeing his panicked face, King Xian asked unhappily:

"Why are you so alarmed?"

Jiang Hao leaned in and whispered:

"Great King, Yu Fu's body was found in the Xuanting Marquis's Mansion."

"Who is it, why did he die in the Xuanting Marquis's Mansion."

Jiang Hao slurred:

"Yes, it is the cook of the Xuanting Pavilion, yesterday's suckling pig was fired by him, and he has a close relationship with the Xuanting Hou, and often cooks delicacies for the Hou Mansion. Yesterday, before the Xuanting Pavilion closed, it suddenly disappeared, General Wei and the adults suspected that it was his poisoning to block the Great Sima, so the whole city was searched, but after dark, the Xuanting Marquis Mansion found the body of Yu Fu in the ice cellar, and reported to the county guard's mansion, it is said that he also died of salt poison. ”

"What!" King Xian was taken aback: "How can there be such a thing, how can there be a reason to kill people and hide the corpse in the house, what is the similarity and difference between this and planting blame!" ”

At the same time that the whole city failed to search for Yu Fu, the ice that was transported from Yongxing City to Chengling City by water had already arrived outside the moat, and was transported into the city by horse-drawn carriage and delivered to the ordering households.

The Xuanting Hou Mansion is one of them, and it is replenished once every three days, and when the ice was pulled into the ice cellar tonight, a frozen corpse was found lying in the ice cellar, which almost scared the Xuanting Hou family to death.

The housekeeper Ma Qing immediately recognized that the deceased was Yu Fu, so he really wanted to cry without tears, isn't this a naked slap in the face without three hundred taels of silver here.

The news was reported to the government, Bai Liyan (Wei Xian) personally examined the autopsy, and also died of sodium nitrite poisoning, and immediately cut open the abdominal cavity and found some suckling pigs from the stomach and intestines that had not had time to digest.

"King, the matter is now extremely unfavorable to Xuanting Hou, the news from all sides, Jiang Yan's old ministry has a lot of complaints in private, if it goes on like this, I'm afraid something will happen!"

"What about Wei Xian, what the hell did he do!"

"General Wei is refining acid and urine water and pork bones [Note 1], I don't know what to do."

"Refining acid nitrate and pork bones!" King Xian was incredulous, frowned and asked, "What can he say for what?" ”

"I didn't say this, but I found three copper chips in the upper room of the Red Lantern Garden from Yu Fu's body, and General Wei has already asked people to seal the Red Lantern Garden, and is sending people to check all the people who have been to the Red Lantern Garden within ten days."

"Red Lantern Garden? Isn't that the largest brothel in the east of the city, can Xuan Tinghou have the guts? No, I can't. ”

King Xian seemed to be quite good at what he said, and then Jiang Hao said:

"Back to the king, according to the rhetoric of the Marquis of Xuanting, Yu Fu's annual commission is not enough to go to the Red Lantern Garden a few times, let alone the copper chips in the upper room, and the Hou Ye does not admit that the copper chips were given by him. General Wei suspected that someone had planted a false accusation, so he wanted to investigate the Red Lantern Garden. ”

"Whose property is the Red Lantern Garden?"

"This ......," Jiang Hao wanted to say but stopped.

"Say, whose property is it?"

"Uh...... It is the Marquis of Ding Yang and Gonggong Guo, and in addition, the palace maids who deal with the crimes every year in the palace are all going to the Red Lantern Garden in the end, so this matter is not easy to publicize. ”

"Hmph, hehaha...... Well, well, there's something else that the widow doesn't know. ”

King Xian sarcastically sat on the couch and asked:

"When will Zhao Xun be able to bring troops into the city?"

"Mr. Gao Xun hasn't come back yet, it is reported that the Black Turban Army has been attacking fiercely in the past few days, I'm afraid Zhao Shuai can't get out."

At this time, Uncle Guang said:

"King, this is the Black Turban Army's deliberate mutation of the internal troubles in Chenling, so it is necessary to prepare as soon as possible."

"The old gentleman is saying that there will be great changes in Chenling!"

Uncle Guang nodded, King Xian's eyes narrowed, and he suddenly said:

"Then the widow will see who is going to take the head of the widow! Old man, the widow has taken his leave. Jiang Hao, drive back to the palace! ”

"No!"

King Xian brushed his sleeves away, Uncle Guang's face was solemn, and he said secretly in his heart on crutches:

"It's so fast......"

Uncle Guang said that the change is not only to say that the situation is changing rapidly, but also to mean that the temperament of King Xian can also change in an instant, and the temperament just now is the temperament in King Xian's bones.

At the same time, Baili Yan guarded the Xuanting Hou Mansion to supervise the murder of Jiang Yan.

The three copper chips found in the upper room of the Red Lantern Garden are the main clues, which are important physical evidence to wash away the suspicion of the Xuanting Marquis. For this reason, Baili Yan asked people to take the ten fingerprints of everyone in the Xuanting Hou Mansion and prepared to check them one by one.

At this time, Xuanting Hou Qiao Lian was staying in the inner house, facing the roar of the tigress, like sitting on pins and needles to sleep and eat, even if it was already the second half of the night, there was still no tiredness.

"Princess, my husband really hasn't been to the Red Lantern Garden."

"Hmph, what kind of virtue do you have, this princess can still be unclear, there is a glance at other girls, when this princess doesn't know yes! It's good now, Yu Fu died in his own ice cellar, and he still carried the copper chips of the Red Lantern Garden in his arms, you said that you haven't been there, who believes it now! ”

"Princess, it's all to blame Lao Ma, it's because he didn't take a good look at the yard and let the thieves break in and frame me, is this unclear, who can hide the murderer's body in his own house."

Xuanting Hou said that he was suffering, but Princess Lan Yuan was angry, knocked on the table with one palm, and was angry:

"What does this have to do with Lao Ma, it's not that you have left a handle for people by using people improperly, if you don't go to the Red Lantern Garden, how can you be framed."

"Oh, my Royal Highness the princess, I really didn't go to the Red Lantern Garden for my husband, and I swore to the sky for my husband, I really haven't been there."

"Look at you, I really want to be angry with this princess, I swear to the black turban traitor, you say you still have a conscience, you say!"

"This, this, this...... I'm wronged, I'm wronged......"

Just as the Marquis of Xuan Pavilion was about to kneel down for Princess Lan Yuan, the voice of the steward Ma Qing came from outside the door:

"Master Hou, Madam, General Wei and Lord County Shou want the two of you to go to the front hall to discuss matters."

"You know what's going on." Princess Lan Yuan asked through the door, glared at Xuan Tinghou angrily, pointed to the ground with her right hand, and the meaning couldn't be clearer, and knelt down for the old lady.

Xuanting Hou comprehended, and knelt down first. At this time, Ma Qing said outside the door:

"I don't know, but General Wei seems to have made progress."

"Got it, I'll go with Master Hou in a moment, you step back first."

"No!"

Ma Qing retreated, Xuan Tinghou knelt down and complained, and quickly changed the topic:

"It's really a good son-in-law, I know my father-in-law before I pass the door, and I have it after passing the door. By the way, he is not a fuel-efficient lamp, I can inquire clearly, he has already been on good terms, if Fu'er passes the door, he will not have a good life. ”

"You still dare to use strong words, it's against you! After this limelight, see how this princess cleans you up, hum! ”

Princess Lanyuan rushed away from the door with a fierce momentum, and the Marquis of Xuanting saw that the wind and waves were calm, so he stood up and chased out of the door.

Bai Liyan was in the main hall of the front hall, there were several stacks of yellow paper on the table, three red lantern yuan copper chips were lying on the table, the copper chips were full of black fingerprints, and there was a bowl of water on the side, which was actually silver nitrate.

Silver nitrate encounters sweat to coagulate the cell proteins in the sweat, and then turns black, and in modern times, fingerprints are made visible by silver nitrate reagents, and fingerprints are extracted.

For this purpose, pork bones and boiled bone glue are made into transparencies, and a large number of fingerprints criss-crossed and stacked on top of each other are peeled off from the copper chips, as well as several relatively independent fingerprints.

With today's technology and workload, it is already very rare to be able to extract fingerprints, and it is difficult to separate fingerprints that are stacked and crisscrossed with current technology.

After comparison, in addition to the two fingerprints found by Ma Qing, there is no similarity with the dozen or so fingerprints found on the copper chips, and the four types of fingerprints do not exist, which avoids complicated questioning, comparison and identification.

Due to the differences in genes, heredity, regional customs and race, human fingerprints are theoretically not repeatable, but they can be divided into three categories, and the three categories can be divided into eleven subcategories, and they can be easily distinguished by the naked eye. The three types of fingerprints found by hundreds of people in the Xuanting Hou Mansion are contrary to the four types of fingerprints found in the overall planning, and this alone can exclude the suspicion of the Xuanting Hou Mansion, thus avoiding the complex comparative identification of key fingerprint points.

Wei Xu and Gao Chong'an, one is a county guard, the other is a scribe, and Gao Chongan is engaged in judicial work, even if he does not have the uniqueness of fingerprints and the cognition of criminology, but there are differences between fingerprints and palm prints between people, as long as he asks him to verify and compare them left and right, he will understand the principle.

Nowadays, the cognition of fingerprints only stays at the level of drawing and exclusivity of certificates, and the understanding of unique identification is not profound. But both of them were people from King Xian, and Bai Liyan proposed to identify the Ten Finger Finger Paths to determine the uniqueness, and they had no reason to object.

Luan Chong, however, began to agree with the idea of identifying fingerprints, and was gloating.

He thought that the fingerprints on the copper chip were invisible to the naked eye, so he sat and waited for Baili Yan to be embarrassed, but how did he know that Bai Li Yan was a human being in two lives, and he was a surgeon in his previous life, how could this kind of carving insect skill stump him.

Seeing that Bai Liyan made the copper chip fingerprints visible, and used transparencies to expand the fingerprints, after preliminary comparison, except for Ma Qing, no other fingerprints were found in the Antaihou Mansion. Upon learning the news, Luan Chong immediately turned his face and refused to admit the result, citing the confusion of fingerprints.

When Princess Lanyuan and Xuanting Hou arrived, the atmosphere at the scene immediately became tense.

"General Wei, it's late at night, have you found out the murderer who planted the Hou Mansion?" Princess Lan Yuan said unhappily, complaining somewhat about this prospective son-in-law.

"Princess, after investigation, Lord Wei, Lord Gao, and the last general unanimously agreed that except for the steward Ma Qing, the whole Hou Mansion can rule out the suspicion of killing Yu Fu."

Princess Lan Yuan was first happy, and then surprised, what does it mean that except for Ma Qing, everyone else can rule out the suspicion of killing Yu Fu, isn't this equivalent to saying it in vain. Ma Qing is suspicious, or the Hou Mansion is suspicious, what kind of truth is this.

"General Wei suspects that the steward Ma Qing killed Yu Fu and hid it in the ice cellar, which is too ridiculous." Princess Lan Yuan said angrily.

"Oh no, princess, please be angry. According to the judgment below, Ma Qingding found the body and touched the coordinator of the Red Lantern Garden, so he left a fingerprint, as long as the matter is confirmed, the suspicion of Ma Steward can be ruled out. ”

Without waiting for Bailiyan to finish speaking, Luan Chong said coldly:

"Hmph, the fingerprints under the extension are messy, your General Wei said that there are Ma Qing's fingerprints on the copper chips, but now he says that he can rule out suspicion, how do you know that among the messy fingerprints, there are no fingerprints of other people in the Xuanting Hou Mansion, it is clear that you are favoring the Xuan Ting Hou Mansion and shielding the criminals!"

Hearing this, Princess Lan Yuan was not happy:

"Why did Lord Luan say this, could it be that what General Wei said is not credible!"

"I wouldn't dare, but the death of my father-in-law, the Xuanting Pavilion is difficult to get out of, and the murderer Yu Fu died in the Hou Mansion, and now it is too early to conclude that the death of Yu Fu has nothing to do with the Hou Mansion based on fingerprints."

"General Luan!" Bailiyan said in a deep voice: "Wei has already said before that except for the twins, the fingerprints of people in the world are not the same, and Lord Wei and Master Gao also approve of it. If Lord Luan can find a case where the two fingerprints are the same, and Wei is willing to make amends, what does Lord Luan think. ”

"Hmph, do you still have to say that the relationship between Lord Wei and the Xuanting Marquis Mansion is still going to be said, you are obviously bending the law for personal gain to excuse him!"

Luan Chong's implication is that Bai Liyan is involved in it, and he is still the quasi-son-in-law of Xuan Tinghou, how can he have his own reason to investigate himself.

Speaking of which, Bailiyan naturally ignored Luan Chong. At the moment, time is tight, and he can't spend it here with Luan Chong, and now that the suspicion of the Xuanting Marquis Mansion has been ruled out, he must use his authority to facilitate the further development of the case.

"Lord Wei, Lord Gao, how is the situation in the Red Lantern Garden?"

"As of two hours ago, there were at least five or six hundred guests who had been to the Red Lantern Garden in the past ten days, all of whom were dignitaries and nobles in the city, and it was easy to confront them one by one. Those who can go to the Red Lantern Garden are either rich or expensive, and ordinary people can't go without money. Wei Xu said in detail, which roughly confirmed Bailiyan's guess.

Red Lantern Garden is the first brothel in Tianzihao, and the backers behind it are Guo Pan and Ding Yanghou, and I don't know how many good women have been harmed and how many dirty deeds have been done. But the vast majority of the prostitutes who can enter and leave the Red Lantern Garden are the leading figures in the mausoleum.

Because the brothel is too large and there are many rooms, prostitutes need to use a special copper chip, the front of the copper chip is written with the grade and room number, and the back is marked with black lacquer to mark the number and time of the copper chip every month, as well as the specific time of the woman's period, so as to facilitate the customers to spend on time. When recycling and reusing, simply scrape off the paint with a scraper.

As a kind of pre-sale voucher, the copper chip must be returned to the brothel and recorded the content every time it is consumed. Unconsumed can be allowed to be taken out of storage, consumed and returned at any time, and the nature is somewhat similar to the modern membership card system.

Yu Fu's three copper chips are all the same girl without exception, it is the red card girl of the twelfth row of the Red Lantern Garden, after the preliminary inquiry and investigation of the errand officer, the news from the Red Lantern Garden said that the three copper chips were sold seven days ago, and the buyer was a foreigner.

Asked if Yu Fu went to consume, the brothel did not know who the final consumer was, according to the rules, they only recognized copper chips and not people. Therefore, you have to identify the corpse first, and then you know whether Yu Fu went to the Red Lantern Garden to consume.

[Note 1] Silver nitrate is prepared by obtaining nitric acid, and silver nitrate can denature the protein, so that the protein metabolized by the human body left in the fingerprint can be solidified, and the fingerprint will be black and visible, so as to make the fingerprint visible, which is a commonly used chemical solution for modern fingerprint display. Animal bones can be used to refine film, and in modern times, film is made by adding chemicals and other gums after refining animal bones and leather. Simple animal gel tablets are used to extract fingerprints for identification.
