In the living room of the internal office, Song Yuner and Liu Ruobing had already bathed and changed their clothes, washed away the dust all the way, and sat in the living room talking to Mrs. Bai, Bai Sumei, Qin Zhihui, and Song Qing.

Qin Zhihui said to Song Yun'er: "Miss Song, the day before yesterday, a letter was sent from the county post station, it seems that it was written to you by your father, and I can't contact you, so I will stay in the room, and I will take it for you." ”

When Song Yuner heard that it was a letter from home, she was a little surprised. After a while, Qin Zhihui took a letter back to the living room and handed it to Song Yun'er.

Song Yun'er glanced at the words on the envelope and exclaimed, "Great, my father wrote it to me!" He hurriedly opened the letter and read it.

Unexpectedly, looking at it, Song Yun'er cried.

Everyone was startled and hurriedly gathered around and asked what was going on.

Song Yun'er said while crying, "Woo...... My mother...... My mother is seriously ill, woo...... My dad ...... My dad wants me to go back right away...... Woo."

Liu Ruobing hurriedly asked, "Are you seriously ill?" Does it matter? ”

Song Yun'er cried and shook her head: "I don't know, Dad just said that my mother is seriously ill, woo woo ......" Crying and handed the letter in her hand to Liu Ruobing, "Master......, I want to go back to see my mother...... Woo."

In ancient times, due to the inconvenience of transportation and communication, generally speaking, when family members wrote letters, they used words such as "seriously ill", and in many cases, it meant that they were critically ill or even dead, and they were worried that the person receiving the letter was in a hurry.

Therefore, of course, Liu Ruobing knew the weight of this letter, gently patted Song Yun'er on the shoulder, and said, "Pack your luggage immediately and set off immediately to rush back." ”

Song Yun'er nodded, cried and ran back to the room.

At this moment, the atmosphere in the house suddenly became solemn, and Qin Zhihui instructed the little maid Yuechan to quickly run to the house to inform Yang Qiuchi. Yuechan agreed and was about to leave, when she heard Yang Qiuchi's laughter from the back hall: "What do you call me?" Immediately, he turned out of the back hall with the red silk.

Qin Zhihui hurriedly stepped forward and said, "Husband, Miss Song's family has a letter saying that her aunt is seriously ill and asked her to go back quickly!" ”

Yang Qiuchi was taken aback and hurriedly asked, "How is the condition?" - What about Yun'er? ”

Qin Zhihui shook her head gloomily: "The condition is not very clear, Yun'er went back to the room to pack her things, and she wanted to set off immediately to rush back to Ning Guofu." …… It's a long way, and we're all worried that if we're late, we'll not be able to catch up. ”

"Is she alone? How can that work! Yang Qiuchi said anxiously, looking at Liu Ruobing.

Liu Ruobing pondered for a moment: "In terms of martial arts alone, Yun'er's current cultivation can be obtained anywhere, but she is still young, inexperienced in the rivers and lakes, and in a hurry, I am also worried that she will be in danger on the road." ”

At this time, Song Yun'er had already run back with a small package, saw Yang Qiuchi, and said sadly: "Brother! My mother's ...... Woowoo woo".

Yang Qiuchi walked up to her and gently hugged her shoulders. Song Yun'er burst into tears, threw down the package, and threw herself into Yang Qiuchi's arms.

Yang Qiuchi felt sad in his heart, hugged her lovingly, and comforted her softly.

Song Yun'er cried in Yang Qiuchi's arms and said, "Brother~! I'll go back to see my mother, you have to take care of yourself. ”

Yang Qiuchi gently stroked Song Yun'er's hair, and said softly: "Jiren has his own natural appearance, and my aunt may just be concerned about you, so she pretended to be sick, don't worry too much, Yun'er." ”

"Really?" Song Yun'er wiped her tears and raised her head to look at him, although she knew in her heart that Yang Qiuchi was comforting her, but she was full of hope that what Yang Qiuchi said was true.

"Hmm~!" Yang Qiuchi nodded, and then said: "You go back alone, brother is not at ease, so let's do it, I will send a few brocade guards to accompany you, and there will be a good response on the way." ”

Song Yun'er nodded: "Okay." "To be honest, she is only fifteen years old, and she is still a little scared to let her go back alone, thousands of miles.

Yang Qiuchi instructed the maid to call Xia Ping and send five brocade-clothed guards with strong martial arts and experienced rivers and lakes to accompany Song Yun'er back to Ningguo Mansion. Xia Ping bowed down to receive the order and hurriedly went down to arrange it.

Song Yun'er grabbed Yang Qiuchi's arm and said, "Brother, Yun'er is not by your side, you have to take good care of yourself, don't drink too much wine." ”

Yang Qiuchi looked at her lovingly and smiled: "Little fool, don't worry, brother remember." ”

Song Yun'er said again: "I went back to see my mother, if my mother is really fine, I will rush back immediately, if my mother ...... Woo woo woo", leaning on Yang Qiuchi's shoulder and crying loudly.

Yang Qiuchi heard her cry like a cuckoo crying blood, and couldn't help but break his intestines, hugged her tightly and said softly: "Don't worry, aunt will be fine, it's not easy for you to go back, no matter how aunt is, don't worry, come back when everything is settled, brother will wait for you." ”

Of course, Song Yun'er heard the weight of Yang Qiuchi's words waiting for her, raised her head, looked at Yang Qiuchi with tears in her eyes, smiled reluctantly, remembered that her mother's life and death were unknown, and then cried again.

Qin Zhihui, Song Qing, and Bai Sumei's three concubines all knew Song Yun'er's weight in Yang Qiuchi's heart, and they all went back to their rooms to prepare some light gifts for Song Yun'er to use on the road and go back to her aunt for Song Yun'er.

Everyone told each other again, at this time, the five brocade-clothed guards had already packed up, and the horses were ready, Liu Ruobing was originally going to let Song Yun'er ride the jujube red horse, but this divine horse was too fast, and the five guards couldn't keep up, but Song Yun'er would be left alone. Fortunately, there are Jinyi Guard Post Stations along the way, and with the Jingshi Jinyi Guard waist card of the female guards, the accommodation is very convenient and safe, and there are horses to replace.

Everyone has been sending them outside the yamen, Yang Qiuchi took Song Yuner's hand, since the first day of crossing to the Ming Dynasty, this little girl with a bit of ambition has been following her, it can be said that she was born and died, although she inevitably stumbled, but friendship followed.

Yang Qiuchi was used to Song Yun'er following him like a little tail, and now he was suddenly separating, and he felt very uncomfortable.

Song Yun'er was even more so, crying and holding Yang Qiuchi's hand until she reached the door, then she let go, and sobbed and told Yang Qiuchi: "Brother, Yun'er is gone." Yang Qiuchi felt sorry in his heart, and couldn't help but gently hug her into his arms, kissed her face full of tears, and said, "Be careful on the road!" ”

Song Yun'er had tears in her eyes, the corners of her mouth showed a hint of joy, nodded, left Yang Qiuchi's embrace, recognised her horse, turned her head to Liu Ruobing and said, "Master, my brother's safety is up to you." ”

Liu Ruobing stood at the door, nodded slightly, and did not speak.

Song Yun'er arched her hand to the people who saw her off, and then she stared at Yang Qiuchi, her beautiful eyes were full of tears, she turned her head suddenly, shook the reins of her horse, and galloped away with five female guards.

Back at the inner office, everyone was very depressed, and after a conversation, they went back to their rooms to rest.

Although Song Yun'er's departure made Yang Qiuchi very uncomfortable, his work still had to be done, he asked Song Qing and Hong Aya to go back to sleep first, and he had to test the samples extracted this time.

Yang Qiuchi's large aluminum cabinet was placed in the study, which was also his forensic laboratory.

First of all, the extracted [***] content sample should be inspected.

He first carried out a mixed agglutination reaction, and only one blood type was detected, which made Yang Qiuchi slightly strange, could it be that the murderer's blood type was the same as the deceased's blood type?

Subsequently, he centrifuged the sample and stained the sediment smear, and then performed a microscopic examination, and the result was very surprising, he could not find any trace of sperm in the sample! It's weird.

Yang Qiuchi immediately conducted a special antigen test on the sample, and as a result, no acid phosphatase contained in the semen was found! The sensitivity of this acid phosphatase test is very high, and it can be detected as long as there is a drop of semen in a large basin of water.

Yang Qiuchi did not give up, and made an anti-sperm precipitation reaction on the supernatant after centrifugation just now, and the result was Yin! This means that there is no semen in the contents of [***] at all!

This is strange, how can there be no semen? It's easy to understand now - the murderer used a condom, but now it's in the Ming Dynasty. Could it be that the murderer didn't force Zhao Qinglan at all? Or in vitro ejaculation? Or did you ejaculate in another area, such as in your mouth?

Fortunately, in order to control the blood type, I took an oral saliva sample.

Yang Qiuchi did another test on the oral sample to find semen, but the result made him very frustrated, and there was no trace of semen either!

The murderer did not leave physical evidence of bodily fluids on the deceased, and Yang Qiuchi was disappointed and immediately searched for fingerprint traces of the deceased Zhao Qinglan's dress.

He decided to focus on detecting the fingerprints on the deceased's underwear, if the fingerprints found on the deceased's underwear were not the deceased Zhao Qinglan or Wang Dianshi, then it is certain that they were left by the murderer when he took off the deceased's clothes.

After reacting with uranium acetate zinc solution and the colorless sweat and dirt fingerprints on the cotton coat, and then irradiating them with ultraviolet lamps, the fingerprints will fluoresce and appear. After testing, there were a few fingerprints in the position where Xiaoyi's sword was pressed, and after Yang Qiuchi took pictures with a digital camera, he immediately went to the cell to extract Wang Dianshi's fingerprints on both hands.

He compared the fingerprints on Xiaoyi with those of Wang Dianshi and Zhao Qinglan, and eliminated them one by one, hoping to find unfamiliar fingerprints that were not the two of them.

However, Yang Qiuchi was disappointed again, the fingerprints of the deceased Zhao Qinglan's clothes were all from Zhao Qinglan and Wang Dianshi!

Could it be that the murderer didn't touch Zhao Qinglan at that time, but restrained her with a murder weapon and forced her to strip off her dress, so there were no fingerprints of the murderer left on the dress?

Yang Qiuchi did not give up and conducted a fingerprint test on Zhao Qinglan's coat, but he was unable to find fingerprints. It's easy to understand, it's raining on site these days, and the coat is soaked and washed by the rain, so fingerprints can't be found.

Yang Qiuchi put the last ray of hope on the sword, and used the magnetic fingerprint brush to detect the fingerprint of the sword, and the same result, no fingerprints were found on the sword washed by the rain!

All hope has turned into disappointment, is it true that the case of Zhao Qinglan, who was cut off by his head, is really a headless case!
