In the living room of the inner yamen, Song Yuner and Feng Ruobing had already taken a shower and changed their clothes, washed away the dust all the way, and sat in the living room and talked to Mrs. Bai, Bai Sumei, Qin Zhihui, and Song Qing.

Qin Zhihui said to Song Yuner: "Miss Song, the day before yesterday, I sent a letter from the county post station. It seemed that your father wrote to you. If I can't contact you, I will stay in the room. I'll take it for you now."

When Song Yun'er 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 Yuner glanced at the writing of the envelope and shouted: "It's great, it was written by my father!" She hurriedly opened the letter and read it.

Unexpectedly, as she looked, Song Yuner started crying.

Everyone was startled and hurriedly surrounded him and asked what had happened.

Song Yuner cried and said, "Wuwu, my mother, my mother is seriously ill, wuwu, my father, my father wants me to go back immediately wuwu."

Zhang Ruobing hurriedly asked: "Is it serious? Is it important?"

Song Yuner cried and shook her head: "I don't know, my father just said that my mother was seriously ill, wuwu." She cried and handed the letter in her hand to Bai Ruobing, "Master, I want to go back to see my mother wuwuwu."

In ancient times, due to inconvenience in transportation and communication, generally speaking, when family members wrote letters, they used words like "severely ill", which in many cases meant that they were critically ill or even died. They were worried that the person receiving the letter was anxious, so they said it implicitly.

So, of course, Feng Ruobing knew the weight of the letter, gently patted Song Yuner on the shoulder and said, "Pack up your luggage immediately and set off to rush back immediately."

Song Yuner nodded and ran back to the room crying.

Suddenly the atmosphere in the room became solemn. Qin Zhihui ordered the little maid Yuechan to run to the house to inform Yang Qiuchi. Yuechan agreed and was about to leave when she heard Yang Qiuchi's laughter coming from the back hall: "What are you calling me?" Then, she took Hong Ling out of the back hall.

Qin Zhihui rushed forward and said, "Huru, Miss Song's letter came from her home saying that her aunt was seriously ill and asked her to go back quickly!"

Yang Qiuchi was shocked and asked, "How is the condition? Where is Yun'er?"

Qin Zhihui shook her head with a sad expression: "I don't know much about the condition. Yun'er went back to her room to pack her things. She had to set off immediately to Ningguo Mansion to get the long way. We are all worried that if we go too late, we may not be able to catch up."

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

Wu Ruobing pondered for a moment: "In terms of martial arts alone, Yun'er's current cultivation level can be anywhere. However, she is still young and has insufficient experience in the world, and is in a hurry to rush. I am also worried that there will be danger on her way."

At this time, Song Yuner had already carried a small package and ran back. When she saw Yang Qiuchi, she said sadly: "Brother! My mother, she whimpered."

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

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

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

Yang Qiuchi gently stroked Song Yuner's hair and said softly: "Auspicious people have their own appearance. My aunt may just care about you, so she pretended to be sick. Don't worry too much, Yuner."

"Really?" Song Yuner wiped her tears and looked up at him. Although she was retaken by Yang Qiuchi, she was comforting her, but she was full of hope that what Yang Qiuchi said was true.

"Yeah!" Yang Qiuchi nodded and continued, "You are going back alone, I'm not relieved. Let's do this. I'll send a few female guards of the Jinyiwei to accompany you, so there's a way to take care of you."

Song Yuner nodded: "Okay." To be honest, she was only fifteen years old, and she was still a little scared when she asked her to go back alone for thousands of miles.

Yang Qiuchi haha, the maid called Xia Ping and sent five martial arts and Honghu experience to the Jinyiwei female guards with Song Yuner to return to Ningguo Mansion. Xia Ping bowed to take the order and hurried down to make arrangements.

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

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

Song Yuner said again: "I went back to see my mother. If my mother was really okay, I would come back immediately. If my mother was whispering," leaned against Yang Qiuchi's shoulder and cried loudly.

Yang Qiuchi heard her crying blood as if Du Juan was sobbing, and couldn't help but feel heartbroken. She hugged her tightly and said softly: "Don't worry, aunt will not have any trouble. It's not easy for you to go back. No matter what your aunt is like, don't worry. When everything is settled before coming back, I will wait for you."

Of course, Song Yuner heard the weight of Yang Qiuchi waiting for her words. She raised her head, looked at Yang Qiuchi with tears in her eyes, and smiled hard. Thinking of her mother's life and death, she started crying again.

Qin Zhihui, Song Qing and Bai Sumei all knew the weight of Song Yuner in Yang Qiuchi's mind. They all went back to their room to prepare some light gifts for Song Yuner on the road and gave them to her aunt when they returned. Anyway, they were accompanied by the guards, so they would not be burdensome.

Everyone reminded each other again. At this time, the five female guards of the Jinyiwei had already packed up and stopped working, and the horses were ready. Bai Ruobing was originally planning to let Song Yuner ride a red horse, but the speed of this divine horse was too fast and the five guards could not keep up. Instead, Song Yuner would be single. Fortunately, there were Jinyi Er Inn along the way, so that the female guards' Beijing Jinyiwei's waist-branded food and accommodation were very convenient and safe, and there were horses for replacement.

As soon as everyone sent them out of the yamen, Yang Qiuchi San held Song Yuner's hand. Since the first day of traveling to the Ming Dynasty, this little girl who was chattering and having a little wild spirit has been following her. She can be said to be born and die. Although she is inevitably stumbling, her friendship is with her.

Yang Qiuchi has become accustomed to Song Yuner following her like a small tail. Now she is about to part ways and feels very uncomfortable.

Song Yun'er was even more so. She cried and took Yang Qiuchi's hand to the outside of the door. Then she let go and sobbed Yang Qiuchi, "Brother, Yun'er is gone." Yang Qiuchi felt sorry for her and couldn't help but hug her gently in her arms. She kissed her face full of tears, and said, "Be careful on the road!"

Song Yuner had tears in her eyes, a hint of joy appeared on the corner of her mouth, and nodded. She left Yang Qiuchi's arms, kicked up the horse, turned to her head and said to Zhang Ruobing, "Master, I'll ask you for my brother's safety."

Shan Ruobing stood at the door, nodded slightly, and said nothing.

Song Yun'er bowed to the people who saw him off, then stared at Yang Qiuchi, her beautiful eyes filled with tears. She turned her head suddenly, shook the reins of the horse, and rushed away with five female guards.

When we returned to the inner yard, everyone was in a depressed mood. After talking for a while, they went back to their room to rest.

Although Song Yuner's departure made Yang Qiuchi very uncomfortable, he still had to do his job. He asked Song Qing and Hong Ling to go back to sleep first, and he wanted to inspect the materials extracted from the geological examination this time.

Yang Qiuchi's aluminum alloy cabinet is placed in the study room, which is his forensic laboratory.

First of all, we need to react to the extracted mixed agglutination reaction, and only one blood type was detected, which made Yang Qiuchi slightly strange. Could it be that the blood type of the murderer was the same as the blood type of the deceased?

Afterwards, he stained the sediment smear after centrifugation of the village, and then conducted a microscope examination. The result surprised him. There was no trace of sperm in the examination material! It was strange.

Yang Qiuchi immediately conducted special antigen tests on the test material, but the acid phosphatase contained in the semen was not found! The sensitivity of this acid enzyme detection test is very high. As long as there is a drop of semen in a large basin of water, it can be detected.

Yang Qiuchi did not give up and responded to the supernatant after centrifugation, and the result was negative! That is to say, there was no semen in the vaginal contents!

This is strange, how could there be no semen? If it is now, it is easy to understand - the murderer used a condom, but it is now in the Ming Dynasty. Did the murderer not rape Zhao Qinglan at all? Or ejaculated outside the body? Or ejaculated in other parts, such as in the mouth?

Fortunately, I extracted oral saliva test materials for the control of blood type.

Yang Qiuchi performed a test on the oral examination materials to find semen, but the result made him very frustrated, and no trace of semen was found!

The murderer did not leave any physical evidence on the deceased. Yang Qiuchi was very disappointed and immediately searched for fingerprints on the deceased Zhao Qinglan's dress.

He decided to focus on detecting the fingerprints on the deceased's close-fitting garment. If the fingerprints found on the deceased's little clothes were not from the deceased Zhao Qinglan or Wang Dianshi, then it is probably 60% certain that it was left by the murderer when he took off the deceased's clothes.

After reacting with the colorless sweat dirt fingerprint on the cotton jacket, the fingerprint will be emitted with ultraviolet lights, and the fingerprint will emit fluorescence and appear. After testing, several fingerprints are indeed left in the position where the little clothing sword is pressed down. After Yang Qiuchi took a photo with a digital camera, he immediately went to the cell to extract Wang Dianshi's two-hand fingerprint.

He compared the fingerprints on his shirt with those of Wang Dianshi and Zhao Qinglan, and ruled them out one by one, hoping to find strange fingerprints that were not the two of them.

However, Yang Qiuchi was disappointed again. The fingerprints of the deceased Zhao Qinglan’s little robe were all from Zhao Qinglan and Wang Dianshi!

Could it be that the murderer did not touch Zhao Qinglan at that time, but instead used a weapon to control him and forced her to take off her dress. So, did the murderer's fingerprints be left on the dress?

Yang Qiuchi was not giving up and tested Zhao Qinglan's coat fingerprints, but failed to find the fingerprints. This is easy to understand. It has rained on the scene these days, and the coat was soaked in rain, so the fingerprints could not be found.

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