The ice sword in Xiaoxiao's hand drew two dazzling cold lights again, with two hissing sounds, and the two teeth cracked in half. Then the sword in his hand pulled a sword flower and disappeared in a whizzy way, and I don't know where it was hidden.

Lu Jinping's hand was trembling and he went up to check it out. At this moment, he saw that the pulp of the tooth was still relatively normal, and he couldn't help but jump in his heart.

Lu Jinping's eyes fell on another tooth and found that it was also carbonized. In other words, the only thing he could count on was the pulp of the teeth that looked slightly normal in the previous color.

Why are all teeth baked and carbonized at high temperatures, but this one survived in high temperatures? Lu Jinping's eyes swept across the cheeks of the deceased and suddenly thought that this tooth happened to be the tooth where the dog hair was sandwiched in the gaps between the teeth. Since that small thighs can be preserved in the fire, the teeth must be the same, why didn't he think of this?

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

Lu Jinping was overjoyed and said to Ye Qingqing, "I'm going to go for a test soon, so I won't be with you."

Seeing that he was so happy, Xiaoxiao could see how helpful it was to split the teeth. She was also happy in her heart. She smiled and said, "Okay, don't worry about me, go and do your business, I'm leaving." She quickly walked out and floated away.

Lu Jinping held the tooth in both hands and watched her disappear outside the yard. Then he ordered the servant to prepare a horse to send him home because his forensic investigation box was placed at home.

When he got home, he closed the door and tested the pulp of the tooth DNA.

During the entire inspection process, his heart almost popped up. This was the last spark, the last hope. When the DNA typing result was revealed on the microcomputer LCD screen, 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 extracted from the cellar of the Turkic Li Ping family and the carriage to compare. The results showed that the three were completely consistent!

This means that the blood in the cellar of Li Ping and the carriage are all victims. Li Ping or his family are suspected of committing the crime!

After obtaining this crucial evidence, although this evidence cannot be used as evidence for the Tang Dynasty. However, Lu Jinping decided to close the net and arrest Li Ping for a surprise interrogation. He hoped to pry open his mouth. The most critical evidence of the Tang Dynasty was confession. As long as the king of evidence was obtained, the case could be concluded.

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

He called Captain Xiong and ordered the constable and Min Zhuang to join forces with murderous intent to go straight to the village where Li Ping's family is outside the city.

When the large group of generals 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 stood at the door, looking at Lu Jinping and the others. But before he could speak, Captain Xiong had already given an order. Several detectives rushed up and pressed him down, tied him up in large numbers.

Lu Jinping ordered everyone in Li Ping's family to be called to the yard. Li Ping and his family were suspected of committing crimes, so all investigations must be carried out.

After investigation, I learned that Li Ping's parents were both present, his father was seriously ill and paralyzed in bed, his mother was old, and his wife and two children. The child was only a few years old.

At the same time, it was also found that Li Ping's wife had a sister of her compatriots who had returned to the Turkic businessman a few days ago. Because there was no corresponding evidence to prove that her sister was involved in the crime, Lu Jinping did not decide to issue a public arrest document to arrest her sister.

Afterwards, Lu Jinping ordered Li Ping and his family to be brought to the yamen.

Although Lu Jinping knew that torture and forced confessions might play a role at this time. If he handed them over to Captain Xiong and their interrogation, they might get confessions faster, but Lu Jinping did not do so. Even if there was already important evidence in hand, Lu Jinping did not intend to use torture and forced confessions, because although he was DNA evidence and claimed to be the king of new evidence, this evidence can only prove a piece of the case and cannot prove the full picture of the case. Therefore, corresponding evidence must be further obtained to obtain the final conclusion.

Lu Jinping did not expect that during the interrogation, Li Ping always denied that he had killed and burned the body. He almost used roars and scolded Lu Jinping's question, saying that the Tang Dynasty bullied them Turkic people and could not solve the case, so he treated them as a goat, and he would not let him go even if he was a ghost.

Although the head captain Xiong and others next to him were furious and asked them to be tried and pried open his mouth, Lu Jinping shook his head and refused.

Because, from the interrogation, he felt that Li Ping's denial was different from cunning denial. He could feel from Li Ping's angry expression that he seemed to be confused about this matter, and he didn't even know the blood stains in his car and cellar. The blood was found by Lu Jinping through high-tech means that he had been ahead of him for more than a thousand years. The blood stains had been cleaned before.

So Lu Jinping turned to ask his family.

He did not use torture to Li Ping, and of course he would not use such a method to his family, women, children, and children.

During the interrogation, Li Ping's parents, wife and children both tried their best to complain, not only to complain about himself, but also to complain about Li Ping's complain. He said that he had a bad temper and spoke very erratic, but in fact he was kind-hearted and did not believe that he would kill people.

The interrogation lasted for three days. Of course, Lu Jinping still guaranteed their sleep time in the middle and did not use disguised torture such as fatigue interrogation, but the results obtained were still unable to find out the truth he hoped for.

Helplessly, Lu Jinping had no choice but to order Li Ping's family to be released first, but Li Ping was still detained and prepared to interrogate further.

If the deadlock cannot be opened for a long time, then people must be released. Li Ping is a Turkic native. If he wants to leave the Tang Dynasty after he is released, he cannot stop him without evidence to prove that he committed a crime. Once he leaves the Tang Dynasty, this case will be difficult to investigate again.

Now, Lu Jinping feels like he is difficult to get off the tiger.

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

It's a day off and it's just dawn.

Because Lu Jinping had something in mind, he didn't sleep well and woke up very early, but he was still lying in bed to think about the case.

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

When he heard Ye Qingqing say this, Lu Jinping immediately knew the purpose of Yunzi coming.

The two had already agreed to go out alone to play last time, and Yunzi should have come for this purpose. But now the Lu Jinping case is in a deadlock and he has no worries to go out to play.

But we can't let others wait in the flower hall. Lu Jinping had to bite the bullet and get up and put on his clothes to the flower hall in front, thinking about how to push this matter back.

When she arrived at the front hall, she saw Yunzi wearing a festive clothing, a fox fur hat, a narrow-sleeved robe with a slanted royal blue robe, a red ribbon tied around her waist, and took off her right sleeve and wrapped it around her waist, revealing a big red embroidered top inside. There were several strings of waist pendants inlaid with jewels such as rosy, red coral, and other jewelry hanging on the other side, and an exquisite waist knife hung on it, which was a unique exotic style.

The most conspicuous thing is that her bulging breasts are originally full and round, and it looks even more straight under the ribbon around her waist.

Seeing Lu Jinping come out, Yunzi ran up happily, looked back, and saw Ye Qingqing not following him. Standing outside the door, she didn't look at them, then she came to Lu Jinping's ear and said in a low voice: "Today is a holiday. How about the matter we have discussed? No problem? If there is no problem, then let's go. I agreed not to take your girl! I have prepared a horse for you, just outside your house gate. You just need to find an excuse to go out with me."

Speaking of this, Yunzi laughed and said to Lu Jinping: "You don't like hunting because your archery skills are not good. To practice archery skills well, you must have a good bow that matches your hands. I have created a longbow for you in the past few days based on your hand strength. The last time the bow was too casual and too ordinary. I specially customized it this time. I specially selected the best weapon shop in Tongzhou to create for you based on your arm length and height, and the carved feather arrows are also customized."

Speaking of this, Yunzi said proudly: "By the way, I used a carefully selected anti-slip rope to help you slimly wrap three layers in the hand-holding position on this longbow that I custom-made for you. In this way, you won't slip your hands. When shooting archery, your arms are forced and nervous, and your palms are easy to sweat. If you don't wrap the anti-slip rope, it will easily slip and you won't hold it tightly. After wrapping it with the rope, the sweat on your hands can soak into the three layers of anti-slip ropes, and it won't slip..."

Lu Jinping was originally thinking about how to refuse, but after hearing her words, he couldn't help but feel his heart moved and stared at her. After a moment, he suddenly screamed, grabbed her shoulder and shook it and said, "You are so smart. You are the smartest woman in the world! That's great, why didn't I expect it? I'm such a pig's head! That's great, you are so smart! Hahaha."

Yunzi was a little confused by his words, but when he heard him praise him, he was also a little confused. Because what he said just now did not show how smart he was. If it was careful and considerate, Lu Jinping used the word "smart" and always felt that he was not praising it. However, before he could correct the other party's statement, Lu Jinping had already let her go and said, "I'm sorry, you have to wait for me for a while. I have another very important thing to do."

"Where are you going? I'll go with you. We'll do our business after we finish our work."

Lu Jinping didn't bother to explain more and said, "That's fine, then you go with me."

Let's talk, Lu Jinping stepped out of the door.

Although Ye Qingqing at the door didn't look at them, she kept listening with her ears on her back. Except for what Yunzi said to Lu Jinping, she didn't hear clearly, she heard everything else. When she heard Lu Jinping kept praising Yunzi and wanted to take Yunzi out for something, she quickly turned around and asked, "Where is the Lord going?"

"Hurry up and bring my forensic survey box."

Ye Qingqing agreed and walked quickly to the inner house.

Taking advantage of this time, Yunzi quickly said to Lu Jinping: "I promised not to take her!"

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

When Ye Qingqing brought the forensic investigation box, he carried it out and ran out. Ye Qingqing followed him to the gate of the courtyard as usual. At this time, Lu Jinping saw Yunzi staring at him with beautiful almond eyes, full of anger. Lu Jinping remembered what he had just said and stopped. It seemed as if he suddenly remembered something, and said to Ye Qingqing: "By the way, go to my study and bring me the second-last row of "Yonghui Lu" on the bookshelf."

Ye Qingqing quickly agreed, turned around and ran a few steps, suddenly remembered something and stopped again, and turned around and said, "Sir. "Yonghui Rule" is not on the top row, it is on your desk. You read it last night."

Lu Jinping just said this casually, but he didn't expect Ye Qingqing to pay attention to the placement of the book he was reading. He corrected his statement immediately and suddenly felt a black head. He smiled and said with a hurried smile: "Yes, I remember it wrong. It's the one on the table, go and get it. By the way, there are also pens, ink, paper and ink."

Ye Qingqing quickly agreed and ran away.

Seeing her figure turning around the corner of the room, Lu Jinping immediately turned around and said, "Go away!"

Yunzi then realized that Lu Jinping was intentionally supporting Ye Qingqing, and his pretty face suddenly opened with a bright smile, and he followed Lu Jinping toward the gate of the yard.

Lu Jinping said to the doorman who was standing beside the yard gate: "When Qingqing comes, tell her. Let her wait for me at home. I have something to do when I go out, come back immediately, tell her not to go away. Just wait for me at home, and I will come back soon!"

The concierge hurriedly agreed.

After leaving the yard, two horses were tied to the horse stake not far from the yard. It was exactly what Yunzi prepared. The two of them rolled over their horses, Lu Jinping led the way, Yunzi followed, and they rode their horses away.

As soon as they left, Ye Qingqing carried a box with pen, ink, paper and inkstone, and ran over with the book "Yonghui Rule". He arrived at the door but did not see Lu Jinping.

The concierge smiled and said, "Miss Qingqing, the Lord asked you to wait for him here. He would come back immediately when he went out and asked you not to go away."

Ye Qingqing said oh, stepped out, stood on the steps and looked around. There was no sign of Lu Jinping and the others on the street.

When Lu Jinping talked to Ye Qingqing just now, Lu Jinping did not say where he was going, so Ye Qingqing didn't know that Lu Jinping and the others were rushing to the yamen because it was a day off and the yamen did not go to work. Besides, Lu Jinping had already told her to wait at home and he would come back soon, so Ye Qingqing didn't dare to look for him and could only wait at home.

Lu Jinping led Ye Qingqing to gallop and drove all the way to the yamen. He went straight to the physical evidence warehouse.

The two yamen runners in charge of guarding the physical evidence warehouse saw Lu Jinping and rushed forward to greet him. Lu Jinping ordered the dagger extracted from the scene of the forest fire corpse burning case.

The serrated dagger was put in a box of evidence and sent to Lu Jinping. Lu Jinping took it to his own signing room and said to Yunzi who was following behind: "Sorry, I want to do a test, no one can watch. This way, you go to the flower hall to have tea and wait for me, and I will come to you after I finish my work."

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

"How can you not come if you agree? Don't worry! Keep your word, go quickly." Lu Jinping asked the on-duty attendant to take Yunzi to the flower hall to serve tea and rest.

After Yunzi left, Lu Jinping quickly closed the door of the signing room, then took out the dagger, carefully checked the burnt wrapping rope at the hilt of the knife, and then closed his hands and silently prayed that the inside should not be burned.

Then, he used a knife to gently scrape off the carbonized string wrapped around the handle of the knife, and was very careful little by little.

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

After scraping off the second layer, I finally saw the black and red rope exposed below.

Lu Jinping was ecstatic. Sure enough, the hilt of the dagger was also wrapped with three layers of ropes. Yunzi said reminded him. He originally thought that the rope was wrapped in only one layer, and this layer was obviously carbonized at high temperature. Unexpectedly, there were two layers of ropes under the burnt rope.

Now I see the dawn.

When he peeled off the two charred ropes above, he finally exposed the entire lowest layer of rope below. However, most of them had been scorched by high temperatures, and only two small pieces of dark red ropes near the hilt and the tail of the knife were still basically the same. This was Lu Jinping's last expectation.

The skin cells of the palms of people who use daggers are easily peeled off and adhered to the hilt, or sweat carries skin cells to soak into the hilt. The merchant in Luowo of Tubo said that the rope that the dagger wraps around the hilt has been completely replaced by people, from thick to thin. This means that the DNA substance left by the Luowo merchant in the rope no longer exists. The person who steals the dagger and the person who uses the dagger to commit crimes may have left trace evidence on it.

When a person holds a knife, the tiger's mouth of his palm rubs between the rope wrapped around the dagger and the rope wrapped around the knife, and the skin cells will fall off and adhere to the ropes or fall into the gaps, which may be preserved.

However, generally speaking, the skin cells that fall off the mouth of the tiger's palm are keratinized, and keratinized cells rarely contain nuclei. They must be semi-keratinized cells or cells without keratinization to have nuclei and have testing conditions. Therefore, the location of the sample material extracted from the shank is very critical. If the extracted sample material happens to be keratinized skin cells without nuclei, then DNA typing cannot be detected.

In addition to falling off cells and finding DNA fractal results, Lu Jinping also placed his hopes on sweat in his palms, and the skin cells carrying the nucleus were soaked into the deep layer of the wrapped rope, so that it could be preserved.

After observation and biometric test, Lu Jinping judged that the most likely thing to leave DNA is the gap in the hilt shank, so he used the part of the dagger close to the tiger's mouth as the key detection object.

He cut a small piece of the wound rope in this part, cut it into pieces, and began to test according to the DNA detection procedure.

Unfortunately, no DNA typing was detected. (To be continued)
