The ice sword in Xiaoxiao's hand once again drew two dazzling cold lights, and with two soft sounds, the two teeth split into two halves. Immediately, the long sword in his hand pulled a sword flower, and disappeared with a whish, and I don't know where it was hidden.

Lu Jinping's hands were trembling, and he leaned up to check, and this time, he saw that the pulp color of this tooth was still relatively normal, and he couldn't help but jump wildly in his heart.

Lu Jinping's gaze fell on the other tooth and found that it had also been carbonized. In other words, the only thing he could count on was the pulp of the tooth that looked a little normal in color before.

Why is it that all the teeth are baked and carbonized by high temperatures, but only this one survives in the high temperatures? Lu Jinping's eyes swept over the deceased's cheeks, and he suddenly thought that this tooth happened to be the one where the dog hair was found between the teeth. Since that handful of dog hair can be preserved in the flames, and the teeth must be the same, why didn't he think of this?

The reason for this is that it is very likely that the deceased's tooth happened to be protected by something similar to a stone at the lowest point of his body, and the surrounding ice and snow melted and cooled down, and it became the last thing left for him to hope.

Lu Jinping was overjoyed and said to Ye Qingqing; "I'm going to test it soon, so I won't accompany you."

Xiaoxiao saw that he was so happy, and it could be seen how much it helped him to split this tooth, and she was also happy in her heart, and said with a smile: "Okay, you don't have to worry about me, you go and get busy, I'll go." "Hurry out the door and drift away.

Lu Jinping held the tooth in both hands and watched her disappear outside the hospital, and then ordered the attendant to quickly prepare a horse to send him home, because his forensic investigation box was at home.

When he got home, he closed the door and had his tooth's pulp DNA tested.

During the whole test, one of his hearts almost popped out. This is the last spark, the last hope, when the DNA typing results were revealed on the LCD screen of the microcomputer, Lu Jinping was so ecstatic that he almost cheered loudly.

He suppressed the ecstasy in his heart and immediately called up the DNA test results of the blood samples taken from the cellar of the Turkic Li Ping's house and the carriage for comparison. The results are displayed. The three are exactly the same!

This means that the blood on Li Ping's cellar and carriage was the victim's. -- Li Ping or his family members are suspected of committing a major crime!

got this crucial evidence, although this evidence could not be used as evidence in the Tang Dynasty, Lu Jinping still decided to close the net. Li Ping was arrested for surprise interrogation. Hopefully pry his mouth open. And the most critical evidence in the Tang Dynasty was the confession, as long as the king of evidence was obtained, the case could be conclusive.

After Lu Jinping packed up his things, he rushed back to the yamen with Ye Qingqing.

He called the bear's head catcher and ordered the gathering to catch the people quickly and strongly. The murderous spirit went straight to the village where Li Ping's house was located outside the city.

When the brigade surrounded Li Ping's house and rushed in, Li Ping's family was frightened and didn't know what was going on.

Li Ping still looked like he was not afraid of heaven and earth, standing at the door, looking at Lu Jinping and them. But before he could speak, the bear catcher had already given an order, and several catchers rushed up to press him down, tying him up.

Lu Jinping ordered everyone in Li Ping's family to be called to the courtyard. Li Ping and his family are suspected of committing crimes, so they must all be investigated.

After inquiry. learned that Li Ping's parents were there, his father was seriously ill and paralyzed in bed, his mother was elderly, and his wife and two children were in addition. The child is only a few years old.

At the same time, it was also found out that Li Ping's wife had a half-sister who had returned to Turkia with a Turkic merchant a few days earlier. Because there is no corresponding evidence to prove that her sister participated in the crime, Lu Jinping has not decided to issue a sea arrest document to arrest her sister for the time being.

Subsequently, Lu Jinping ordered Li Ping and his family to be brought to the Yamen.

Although Lu Jinping knew that if torture was used to extract confessions at this time, it might work, and if they were handed over to Xiong Zhutou, they might be able to obtain a confession more quickly for interrogation, but Lu Jinping did not do so. Even if he already has important evidence in hand, Lu Jinping does not plan to use torture to extract confessions, because although he has DNA evidence. is known as the new king of evidence, but this evidence can only prove a fragment of the case, not the whole picture of the case, so it is necessary to obtain further evidence to obtain the final conclusion.

Lu Jinping didn't expect that he was under interrogation. Li Ping has always categorically denied that he killed people and burned his body. His questioning of Lu Jinping almost resisted by roaring and scolding, saying that the Tang Dynasty bullied them Turks, and if they couldn't solve the case, they would be treated as the top criminals, and he would not let them go if he was a ghost, etc.

Although Xiong Zhutou and the others next to him were furious when they heard this, and asked to hand him over to interrogate and pry his mouth open, Lu Jinping shook his head and refused.

Because, from the interrogation, he sensed that Li Ping's outright denial was not the same as cunning denial, and he could feel from Li Ping's angry expression that he really seemed to be at a loss about this matter, and he didn't even know that there were blood stains in his car and cellar. And those blood were found by Lu Jinping through high-tech means that were more than a thousand years ahead, and those blood stains had been cleaned before.

So, Lu Jinping turned to ask his family.

He did not use torture against such a rude person as Li Ping, and of course Lu Jinping would not use such a method against his family, wives and children, and children.

During the interrogation, Li Ping's parents, wives and children all desperately cried out for injustice, not only for themselves, but also mainly for Li Ping. said that he had a bad temper and spoke impulsively, but in fact he was kind in his heart and did not believe that he would kill.

The interrogation lasted for three days, of course, in the middle, Lu Jinping still guaranteed their sleep time, and did not use disguised torture such as fatigue interrogation, but the results he got still failed to find out the truth he wanted.

Helpless, Lu Jinping could only order Li Ping's family to be released first, but Li Ping was still detained, ready for further interrogation.

If the deadlock cannot be opened for a long time, then the person must be released, and Li Ping is a Turk, if he wants to leave Datang after release, he cannot be stopped without evidence to prove his crime, once he leaves Datang, I am afraid that this case will be difficult to investigate.

Now, Lu Jinping has a feeling that it is difficult to ride a tiger.

Just when Lu Jinping was very depressed, Yunzi came to him to relax.

It was a day off, and it was just dawn.

Lu Jinping didn't sleep well because he had something on his mind, and woke up early, but he still lay on the bed and pondered the case.

At this time, Ye Qingqing came in, pouted and told him that Yunzi came to him, dressed as if he was going to celebrate the festival. I don't know what to do.

As soon as he heard Ye Qingqing say this, Lu Jinping immediately knew the purpose of Yunzi's coming.

Last time, the two had already discussed that the two of them would go out to play alone, and Yunzi should have come for this purpose, but now Lu Jinping's case is at an impasse. There's nothing on the mind to go out and play.

But you can't let people wait in the flower hall. Lu Jinping had no choice but to get up and get dressed and come to the flower hall in front, thinking about how to push this matter back.

When she arrived in the antechamber, she saw Yunzi dressed in a festive Tibetan attire, a fox fur hat, and a slanted royal blue robe with narrow sleeves. A red ribbon was tied around his waist, and the sleeve of his right arm was taken off and wrapped around his waist, revealing a bright red embroidered blouse underneath. Around his waist hung several strings of jewels such as roturine and red coral, and on the other side hung a delicate waist knife. It's not like it's exotic.

The most conspicuous thing is the double peaks on her bulging chest, which is originally very full and round, and it is even more upright under the ribbon around her waist.

Seeing Lu Jinping coming out, Yun Zizi ran up happily, glanced back, and saw that Ye Qingqing did not follow. Standing outside the door with his back to them, he didn't look at them, and then he came to Lu Jinping's ear and said in a low voice: "Today is a rest day, how about we discuss something?" No problem, right? If there is no problem, then let's go, and I said that I am not allowed to take your girl! I have prepared a horse for you, just outside the gate of your house. You just have to find an excuse to go out with me. ”

Speaking of this, Yunzi grinned and said to Lu Jinping: "You don't like hunting, mainly because your archery skills are not good. And to practice archery well, you must have a good bow. I've built a longbow for you these days based on your strength. The bow last time was too casual and too ordinary, but this time I made it custom. Based on your arm length and height, I specially selected the best weapon shop in the same state to build for you. And the carved arrows are also custom-made. ”

Speaking of this, Yunzi said quite proudly: "By the way, I have used carefully selected non-slip ropes to help you wrap three layers in the grip position of this custom-made longbow. That way you won't slip your hands. - Arm force when shooting arrows. Coupled with nervousness, the palms of the hands can easily sweat. If you don't have a non-slip rope entangled, it is easy to slip and you can't hold it tightly, and after wrapping it with a rope, the sweat on your hands can soak into the three-layer non-slip rope that wraps it. It won't slip......"

Lu Jinping was originally thinking about how to excuse herself with a bitter face, but when she heard her words, she couldn't help but move in her heart, staring at her, for a moment, she suddenly screamed, grabbed her shoulders and shook her and said, "You are so smart, you are the smartest woman in the world!" Great, I didn't think of it, I'm such a pig's head! Great, you're so smart! Hahaha"

Yunzi was a little puzzled by what he said, but when he praised himself, he was happy and a little puzzled. Because what he just said didn't show how smart he was, if he was careful and considerate, it would be more accurate, but Lu Jinping used the word "smart", and he always felt that he didn't praise the point, but before he could correct the other party's statement, Lu Jinping had already let go of her and said, "I'm sorry, you have to wait for me for a while, I still have a very important thing to do." ”

"Where are you going? I'll go with you, and we'll do our business when we're done." ”

Lu Jinping didn't care to explain more, and said, "That's okay, then you come with me." ”

Let's say, Lu Jinping stepped out of the room.

Although Ye Qingqing at the door didn't look at them, he kept listening with his ears pricked up, except for the words that Yunzi said in Lu Jinping's ear that was too low for her to hear clearly, she heard the other words, and heard Lu Jinping praise Yunzi vigorously, and he wanted to take Yunzi out for something, so he quickly turned around and asked, "Where is the lord going?" ”

"Hurry up and get my forensic investigation kit."

Ye Qingqing agreed, and ran to the inner house as fast as a fly.

Taking advantage of this time, Yunzi hurriedly said to Lu Jinping: "Okay, don't take her!" ”

Lu Jinping didn't care about this at this time, and nodded indiscriminately in agreement.

When Ye Qingqing brought the forensic investigation box, he carried it and ran out. Ye Qingqing, as usual, followed closely to the gate of the courtyard. At this time, Lu Jinping saw Yunzi glaring at him fiercely with a pair of beautiful almond eyes, and his face was full of anger. Lu Jinping remembered what he had just said, and quickly stopped, as if he suddenly remembered something, and said to Ye Qingqing: "By the way, you hurry up and go to my study and bring me the second-to-last "Yonghui Law" on the bookshelf. ”

Ye Qingqing hurriedly agreed, turned around and ran a few steps, and suddenly remembered something and stopped. turned around and said, "Sir, "Yonghui Law" is not in the top row, on your desk, you read it last night." ”

Lu Jinping just said this casually. Unexpectedly, Ye Qingqing paid attention to the placement of the book he was reading, corrected his statement at the moment, and couldn't help but suddenly have a black line on his head, and hurriedly smiled: "Yes, yes, I remembered wrong." It's the one on the table. Go get it. By the way, there is also pen, ink, paper, and inkstone. ”

Ye Qingqing hurriedly agreed and rushed away.

Seeing her figure turn around the corner of the house, Lu Jinping immediately turned around and said, "Hurry up!" ”

Only then did Yunzi understand that Lu Jinping was deliberately supporting Ye Qingqing, and his pretty face suddenly bloomed with a bright smile, and he followed Lu Jinping to the gate of the courtyard.

Lu Jinping said to the gatekeeper who was standing next to the courtyard gate: "When Huiqingqing comes, tell her and let her wait for me at home." I'm out for some business, so I'll be back right away and tell her not to go away. Just wait for me at home and I'll be right back! ”

The porter hurriedly agreed.

After leaving the courtyard gate, two horses were tied to a horse stake not far from the courtyard gate. It was Yunzi who prepared. The two of them turned over and got on their horses, Lu Jinping took the lead, Yunzi followed, and the two rode their horses and galloped away.

As soon as they left, Ye Qingqing ran over with a box containing pen, ink, paper, and inkstones, and the book of "Yonghui Law". When I arrived at the door, I didn't see Lu Jinping.

The porter smiled and said, "Qingqing girl, the lord asked you to wait for him here, he will come back as soon as he goes out for something." He also told you not to go away. ”

Ye Qingqing sighed, stepped out, stood on the steps and looked around, there was no Lu Jinping and them on the street.

When Lu Jinping was talking to Ye Qingqing just now. Lu Jinping didn't say where he was going, so Ye Qingqing didn't know that Lu Jinping was running to the yamen, because it was a rest day, and the yamen didn't go to work. Besides, Lu Jinping has already told her to wait at home, and he will come back soon. Ye Qingqing didn't dare to look for it, so she could only wait at home.

Lu Jinping took Ye Qingqing to gallop on horseback and galloped all the way to Yamen. Go straight to the evidence warehouse.

The two officials in charge of guarding the physical evidence warehouse saw Lu Jinping and hurriedly stepped forward to greet him. Lu Jinping ordered to take out the dagger extracted from the scene of the mountain fire and the cremation of the corpse.

The serrated dagger was sent to Lu Jinping in an evidence box, and Lu Jinping took it to his signature room, and said to Yunzi who was following behind: "I'm sorry, I want to do a test, and no one can watch." In this case, you go to the flower hall to drink tea and wait for me, and I will come to you when I am done. ”

Yunzi said, "Then you are not allowed to coax me, I will wait for you there." If you don't come, I'll wait until tomorrow dawn!" ”

"How can you not come if you say yes? Rest assured! Words count, go ahead. Lu Jinping also asked the attendant on duty to take Yunzi to the flower hall to serve tea and rest.

After Yunzi left, Lu Jinping hurriedly closed the door of the signing room, then took out the dagger, carefully inspected the charred winding rope at the hilt, and then folded his hands and silently prayed that the inside would not be burned.

Then, with a small knife, he gently scraped off the thin rope that had been carbonized on it, wrapped around the handle, little by little, very carefully.

The first layer was scraped off, and the second layer was still completely carbonized, so I had to continue scraping.

Scraping off the second layer, I finally saw the black-red rope exposed underneath.

Lu Jinping was overjoyed, and sure enough, the handle of this dagger was also wrapped in three layers of rope, and what Yunzi said reminded him. He originally thought that there was only one layer of rope wound, and this layer had obviously been carbonized at high temperatures, but he didn't expect that there were two layers of rope under the burnt rope.

Now there is a light at the end of the tunnel.

When he peeled away the top two layers of scorched rope, he finally revealed the entire bottom layer of rope. However, most of it had been scorched by the heat, and only two small patches of dark red rope near the handle and tail remained largely intact. This is Lu Jinping's last expectation.

The skin cells in the palm of the hand of a person who wields a dagger tend to fall off and stick to the hilt, or sweat carries the skin cells into the hilt. The merchant of Tubo Luowo said that the rope with which the dagger was wound around the handle had been completely replaced, from thick to thin. This means that the DNA material that the merchant left on the rope is no longer there, and the person who stole the dagger and the person who used it may have left trace physical evidence on it.

When a person holds a knife, the friction between the mouth of the palm of the hand and the rope around the dagger causes skin cells to fall off and adhere to the rope of the handle or fall into the gap, which may be preserved.

However, generally speaking, the skin cells shed from the palm of the hand are keratinized, and the keratinized cells rarely contain a nucleus, and they must be hemikeratinized cells or cells without keratinization to have a nucleus and be tested for testing. Therefore, the location of the sample from which the handle is extracted is very important, and if the sample is extracted from keratinized skin cells without a nucleus, DNA typing cannot be detected.

In addition to exfoliating cells to search for DNA fractal results, Lu Jinping also pinned his hopes on the sweat of his palms, and the skin cells carrying the nucleus were soaked into the deep layers of the rope to preserve it.

After observation and biological testing, Lu Jinping judged that the most likely place to leave DNA material was the gap between the knife handle, so he took the part of the dagger close to the tiger's mouth as the key detection object.

He cut a small piece of the rope around the area, cut it up, and began to test it according to the DNA testing procedure.

Unfortunately, no human DNA typing has been detected. (To be continued.) )
