When the others heard this, they all changed their color, but they still looked a little hesitant, staring at the tan traces on the ground and asked, "Du Tou, is this blood stain?"

"To be precise, this is the remnant of blood. After they killed someone, they had carefully cleaned the entire yard, so the Guan family seemed extremely clean and tidy inside and outside." Sun Tu said solemnly. Although he only understood the basics of criminal investigation and lacked knowledge of forensic and legal evidence, after all, it came from that era of the explosion of knowledge and information. Naturally, he knew the original method of using vinegar to make the residual blood appear: "It's a pity that it's late autumn now, and there are fewer flies, otherwise there would be no need to waste these tricks."

The subordinates naturally believed him, and the traces in front of them were indeed not fake. This made them more uneasy. This made them feel that the death case was serious, and the responsibility on their shoulders became heavier: "Duzhu, what should we do next?"

This is exactly what made Sun Tu feel a headache. He thought that if he found the Guan family, he could ask for some relevant clues from them, but the case became more serious, so he could only return to the starting point. However, he did not intend to give up the clues here just like this and said to Tang Feng and Gao Shan: "You two stay here first, walk around and visit more in this alley, and ask the neighbors around him if there is any abnormality."

The two agreed first, and then Tang Feng said in confusion: "Du Tou, it is probably Mid-Autumn Festival night during the case. There are not many people left in the alley. How could there be any appearance?"

"What I asked you to ask is not the situation on the Mid-Autumn Festival night, but earlier, to see if there are suspicious people nearby. Since the thieves have done the matter so well, they must have made full preparations, and it is inevitable to check in the spot." Sun Tu explained patiently and emphasized: "Also, it would be better if he could ask where he had been before the incident came out of seclusion. I believe he must have found out what inside information before he was silenced."

The two subordinates quickly agreed without delaying it, so they hurried out to go around to inquire about the news. Sun Tu and the others no longer stayed here and went on horseback. It was not until this time that Ma Huaibang said with some concern: "Officiale Sun, where can we go to investigate the case next?"

"As I told you before, you will go to the homes of some victims to investigate." Sun Tu turned around and ordered his subordinates, "As for me, I will naturally visit Yu Xianggong's mansion." As he said that, he lifted the reins and walked forward quickly.

Yu's family's attitude towards Sun Tu was pretty good. Not only did they go into the side hall and have tea and snacks, but Yu Shen's second son Yu Hang came out to accompany him, which gave him enough face as a ninth-rank official.

Sun Tu did not go too far and went straight to the topic: "The Xiaguan came here to collect clues about the abducted case of Miss Yu, such as before and after the incident, the maids and servants who accompanied him had some unusual situations, or did any suspicious person harassing Miss Yu."

Yu Hang recalled it and then said, "As for the servant who accompanied Die Niang out that day, there was no strange thing that happened that day. Moreover, she had always surrounded her servants, and ordinary disciples did not dare to come forward to disturb her... The only thing that was strange was that they mentioned that several black carriages had passed by. There were many people at that night, and this car was really annoying."

"Then why would she be kidnapped in public?" Sun Tu frowned and said, "Unless she voluntarily left with someone..."

"Sun Du, what do you mean?" Yu Hang's face immediately sank: "Do you want to say that Die Niang is unfaithful?"

"No, the officials have no intention of this, they just felt that this matter was a bit strange. As I said just now, Miss Yu has a maid, but also a slave to guard her. How can an ordinary person be able to get close to you? Even if there are many people on the Mid-Autumn Festival night, they can always take care of this." Speaking of this, Sun Tu felt a little different from other abducted cases.

Other girls who were abducted were ordinary people, so it was convenient to be abducted, and there were not many future problems. However, the granddaughter of Yu Shen's family was superior in dressing and maids and servants surrounded by them. Even if his appearance was outstanding, those bad people would not dare to attack him.

Yu Hang was a little annoyed at this time: "This is what you Kaifeng Prefecture should investigate, why did you ask me instead? Sun Dutou, if Die Niang really has something to do, I, Yu Family, are you asking!"

Sun Tu smiled bitterly and could only make sure that he would do his best to find the thief. Then he asked: "I wonder where the maid and servant who accompanied Miss Yu that day, can I ask a few questions?"

Yu Hang's face was a little strange, and he just snorted: "These people are not doing their jobs well and have been punished and kicked out of the house long ago. Now they are not visible."

When Sun Tu heard this, his expression changed slightly. Although the other party was obscure, he still heard the meaning of the words, which meant that all the maids and slaves were beaten to death. In fact, this is also very common nowadays. Generally, slaves who sell themselves to powerful families will be severely punished if they make mistakes. Even if they lose their lives, there will be many people who lose their lives, and the government will not pursue them. But even though they know that this is as the rules of the lower part today, Sun Tu still feels uncomfortable.

"Is there anything else that Sun Dutou wants to ask? If not, I will forgive me for not being able to accompany me for a long time." Seeing that Sun Tu was a little silent, Yu Hang said impatiently.

Sun Tu then came back to his senses: "There is still the last question. Do you know if Miss Yu has any close friends on weekdays?"

"No, but Die Niang is still waiting to be a member of the word. How could she meet the man outside for no reason?"

Sun Tu smiled in his heart. Isn’t this the place where there is no silver? He asked his friend, but the other party directly mentioned the man, afraid there was something wrong with it. However, Yu Hang definitely couldn’t ask the answer, so he had to get up and say goodbye. The latter seemed a little dissatisfied at this time and did not send him out, but only asked a servant to accompany Sun Tu out.

Sun Tu didn't take this seriously, and even deliberately started talking to the other party. Because the two were not very old, they won over the relationship in a few words. He took the opportunity to ask, "Young man has been here for a while, right? I wonder if you are still familiar with Miss Yu?"

"I'm a young man who only works in a foreign house and rarely see my lady on weekdays." This man was not very scheming and replied casually.

But Sun Tu was not discouraged and continued to ask, "You always know what Miss Yu likes on weekdays, right?"

"This... Miss, she likes some poetry on weekdays, and seems to like reading slogans quite a bit. Sister Qiuping asked me to buy slogans several times before."

"Oh? I didn't expect Miss Yu was still a talented woman, but I wonder who taught her to read and write poetry?"

"It's Jin Yi, but he stopped visiting the door half a year ago." The man said frankly and answered casually. Until he said this, he realized that he was a little too much, and a hint of panic appeared in his eyes. If the owner of the family knew that he had revealed the matter about the lady, he would probably be severely punished.

Sun Tu looked at the other party with a smile: "Then please tell me the place of Jin Yi. Don't worry, I will keep it secret for you." There was a clear threat in this sentence.

The servant was confused at first, but finally couldn't stand Sun Tu's eyes and whispered an address. Sun Tu then patted his shoulder with satisfaction and left.

Jin Yi's residence is not far from Yu's mansion, only two or three streets away. Sun Tu immediately went over to see what was going on, but it turned out that there was already empty house. The iron locks outside the door were covered with thick layers of gray and rust.

Sun Tu immediately asked his neighbors about Jin Yi's situation, and then he realized that he was a scholar who was in a poor family. He was not lucky enough to pass the imperial examination several times. In the end, the land and house at home were almost sold, so he could only go to work as a Western class and teach people to read and recognize words.

"Then why did he leave half a year ago?" Sun Tu asked the key point.

"It was because he offended a high-ranking official. He was driven back at noon that day. In the afternoon, many evil slaves came to the door, discounted his whole hand, and forced him to leave Tokyo immediately, otherwise he would beat him to death. Alas, it was such a sin..." An old man who had seen that scene with his own eyes kept sighing.

"Do you know which official official belongs to that evil slave?"

"It's unknown to this little old man, and this is not something we can do with."

Sun Tu thanked the other party and then returned to Jin Yi's house. He jumped into the yard with just one jump, and then he easily flipped into the yard. The yard of the Jin family is actually not small. If it were sold as a whole, it would be sold at a good price. However, most of the houses here are dilapidated. After opening the door, several rooms have almost been emptied. Only a few pieces of thick wooden furniture in the east wing room, and half of the ink that had already dried up was placed on a desk.

Sun Tu didn't care that the desk was covered with dust and spider webs, and started rummaging around. In a few seconds, he found several letters with words inscribed from a book in the drawer of the desk.

After carefully looking at the content above, Sun Tu's mouth curled up: "It's true that it's the same as I thought."

The paper is about several love poems that sing together, and the handwriting comes from two different people, one is strong and the other looks more graceful, obviously a man and a woman. Although these poems are not of high level and it makes people feel a little numb, the emotions are sincere. Moreover, the words "butterfly" are written by the man many times, so it is naturally obvious who this poem is for.

"It's really an unexpected gain." Sun Tu took a few letters and pushed the whole story out in his heart.

Miss Yu's family is the age of a young girl. Because she has read too many stories about love between men and women, she has developed feelings for the gentleman Jin Yi, who teaches her to read. However, after all, the status of the two of them is very different. After being seen by the Yu family, they have come to break up the couple and directly drive Jin Yi out of Tokyo, thus completely breaking Miss Yu's thoughts.

But no one expected that Jin Yi would come back half a year later, and this time he was more courageous and skilled, so he took the opportunity to kidnap Miss Yu from the people around him on Mid-Autumn Festival night.

Although there is no empirical evidence for this, it is the most reasonable explanation from the current situation. After all, only those who are trusted by Miss Yu will let her act without her family's protection. She is a girl who is waiting for her to be a boudoir and has almost no contact with outsiders on weekdays. Only Jin Yi, who had a relationship with her, had such skills.

"Will the scholar and the lady fall in love with each other and then make a lifelong decision?" Sun Tu put the love poems into his sleeves, looked around and was sure that there was no more. Then he left: "It's a pity that the exhibition of this story is very different from the story of a talented man and a beautiful woman in the novel "speaking of the story!"
