Regarding Zhou's mother's information, Qin Tai and Zhan Xiaoxiao looked at it three times and felt that there was no problem. But not only Qin Tai, but even Zhan Xiaoxiao felt that there was something strange in it. Qiu Xiaoqiu also came to participate, and after reading Zhou's mother's information, he always felt that this information seemed to be done in one go. Qiu Xiaoqiu's words immediately opened the minds of Qin Tai and his wife. Everyone's file will be written paragraph by paragraph, although it has been centralized and sorted out by later generations, but it will definitely not be too smooth. The reason why Zhou's mother's file made Qin Tai and his wife feel strange was because it was too smooth and coherent. If someone can modify it, it means that Zhou's mother's file is fake and someone wrote it. Whether someone can modify Zhou's mother's file or Zhou's mother's file is fake, this is a very serious and dangerous matter. Qin Tai ordered Qiu Xiaoqiu to take the file back to the East Factory, and he must determine the source of this file. Qin Tai took his wife Zhan Xiaoxiao to investigate the scene of Yu Niang's murder again, hoping to find favorable evidence.

Qin Tai and his wife entered Zhang Juzheng's house again, and happened to meet Zhou's mother who went home to get something. This is the first time that Qin Tai and his wife have met Zhou's mother, and Qin Tai has already left the capital when Zhou's mother came to Zhang Juzheng's house, so the two parties have not met. Zhou Madi and Qin Tai and his wife were not too surprised when they appeared at Zhang Juzheng's house, and very politely took Qin Tai and his wife to visit the backyard of Zhang Juzheng's house. After Qin Tai and his wife chatted with Zhou's mother for a few words, Zhou's mother left on the grounds that she was in a hurry to go back because she had something to do. Qin Tai asked his wife Zhan Xiaoxiao to draw a portrait of Zhou's mother immediately, if Zhou's mother's identity is fake, he can only rely on this portrait to find clues. Zhan Xiaoxiao is good at fine brush painting, and under the teaching of the godfather and old drunkard master over the years, he can already rely on his memory to draw portraits that are similar to real people. This kind of technique and ability has played a big role in breaking the fire in some cases, and now Qiu Xiaoqiu has basically learned the ability to sketch.

After inspecting Yu Niang's body and the scene again, Qin Tai found that the murderer was cleaned up very cleanly, and Zhan Xiaoxiao's first investigation was also very careful. But Qin Tai still found two problems. First, Yu Niang's most important property is gone. Yu Niang's family was targeted by the powerful because of Yu Niang's appearance and the family's house deed, and it was because of this that Yu Niang's father and brother died, and Yu Niang was almost sold into a brothel. Therefore, this deed of ownership has a different meaning for Yu Niang, it is the lifeblood of Yu Niang and the dependence of her future life. Under Zhang Juzheng's justice, the deed of the house has been returned to Yu Niang, and Yu Niang is the owner of the house deed. Zhang Juzheng can't look down on this house deed, and it is even more impossible to think that Yu Niang wants this house deed. Yu Niang will definitely bring this deed of ownership with her, and she must have brought it when she came to Zhang Juzheng's house. However, neither Yu Niang's body, nor Yu Niang's jewelry box or secret grid found the house deed and title deed. Either the murderer took it away, or it was taken away by someone, of course, there is also a possibility that the jade lady is spent. Yu Niang doesn't need to spend money, and she won't use this house deed easily, because this house deed is equivalent to her father's brother's life. If Yu Niang really used this house deed and title deed, it must be a very important or important thing, and she can't make it public, so she has to use this house deed in exchange. The second problem is that you have a faint floral fragrance in the jade girl's room. After Yu Niang's death, this order was issued that no one was allowed to enter or leave Yu Niang's room. Yu Niang's room was only entered by the reconnaissance master and Zhan Xiaoxiao from the East Factory. Although Yu Niang will definitely use spices before she is alive, she has been dead for two days, and even if she does not have the smell of corpses, she should not emit the fragrance of flowers. The only explanation is that a woman with the scent of flowers has come in in the past two days. Whether she wanted to steal or take something away, or even destroy some evidence, she didn't expect to leave more obvious evidence behind.

Zhan Xiaoxiao is a woman, and she is also a woman who uses spices, so she knows the use and classification of these spices best. Every woman uses spices to a greater or lesser extent, but according to each woman's age, personality, temperament, identity, status, environment, etc., everyone uses different spices. Young people like to use richer spices, older people like to use more elegant ones, and some girls like to use pure natural ones. For example, when Empress Dowager Li was young, she liked to use precious spices from the Western Regions, but later she disliked that the spices of the Western Regions were too strong, and switched to the more elegant potpourri spices when she got older. Empress Dowager Chen has had a soft spot for jasmine spices since she was young. Mrs. Zhang has been using sandalwood spices for a long time because she believes in Buddhism. Zhan Xiaoxiao likes to use lily spices. It is said that Yu Niang liked to use osmanthus fragrant spices during her lifetime.

This floral fragrance is not the lily smell on Zhan Xiaoxiao's body, nor is it the osmanthus fragrance used by Yu Niang, Zhan Xiaoxiao carefully identified it and felt that it should be a more miscellaneous floral fragrance. The more precious the spice, the more single the material used, almost the essence of pure natural purification. Of course, this price will be very expensive, and ordinary people cannot afford to use this precious spice. Even the spices used in Zhanxiao are medium colors, and they are reluctant to use too expensive superior colors. The fragrance in Yu Niang's room is not only the cheapest spice, but also the one they make in private. So not only is the taste impure but also a little pungent, and ordinary women with status will not use this spice. The women who use this spice are either maids or girls from ordinary small families.

The person who can enter and exit Yu Niang's room at will, and is more familiar with Yu Niang's room, is most likely the maid who serves Yu Niang. She will definitely not be the murderer who killed her for a year, otherwise she would not enter Yu Niang's room again. The only possibility is that she wants to take advantage of this opportunity when everyone is not at home to steal. The maid is a native of the capital and a girl hired by Zhang Juzheng. According to the contract, in addition to being favored by Zhang Juzheng, the maid will leave Zhang Juzheng's house when she is 20 years old, or marry Zhang Juzheng's subordinates under Zhang Juzheng's arrangement and continue to stay in Zhang Juzheng's house. This maid must not want to stay, so she has the audacity to steal some things from the master's family, and prepares to serve as her own dowry when she marries in the future. Whether Yu Niang's house deed will be in her hands or not, and whether she knows some inside information, so Qin Tai decided to contact this maid head-on.

Qin Tai asked Zhan Xiaoxiao to bring this maid over, and Zhan Xiaoxiao quickly found this maid named Xiaoli in the lower room not far from Yu Niang's room. Xiaoli was originally a maid in Zhang Juzheng's family, and she was unwilling to cooperate with Zhan Xiaoxiao and Qin Tai. Unexpectedly, Qin Tai had Zhang Juzheng's investigation in his hands, and Zhan Xiaoxiao was a ruthless person, Xiaoli didn't dare to contradict Qin Tai and his wife. Qin Tai asked what Xiaoli would answer obediently, not daring to hide or exaggerate.

At this time, Zhang Juzheng's deputy captain of the guard came back to do errands, and Xiaoli hurriedly stopped him in the hope of saving her. Unexpectedly, the deputy captain who had been by Zhang Juzheng's side for a long time knew Qin Tai and his wife, not only did not help Xiaoli, but also asked Xiaoli to actively cooperate with Qin Tai and his wife. Xiaoli answered the question helplessly, not daring to have any luck. Qin Tai and his wife finally knew some doubts in their hearts, and even more aware of the contradictions between Yu Niang and Mrs. Zhang.

Xiaoli told Qin Tai that after Yu Niang came to the house, she would take care of Yu Niang. But Yu Niang seems to have a bit of a cleanliness habit, and Xiao Li is not allowed to touch Yu Niang's belongings casually. So Xiaoli is not very familiar with the placement of Yu Niang's things, especially valuables, almost nothing. When Yu Niang first came, Xiaoli was jealous and looked down on Yu Niang. Xiaoli's background is similar to that of Yu Niang, and she also tries girls from poor families near the capital, why is Xiaoli a maid and Yu Niang is the master when she comes? Yu Niang is just better looking than Xiaoli and can seduce men, but let Xiao Li serve Yu Niang. Yu Niang doesn't know if she doesn't trust Xiaoli or if she is not used to being served by others, so she doesn't like Xiaoli to follow her and often go in and out of her room. This made Xiaoli hate Yu Niang even more, and she kept slandering Yu Niang behind her back, saying that Yu Niang was a cheap woman who took the initiative to seduce the lord without face. In order to achieve the purpose of slandering and squeezing out Yu Niang, Xiaoli slandered Yu Niang as a person who lives an indecent life and likes to be powerful to his subordinates. Therefore, the reputation of Yu Niang in the impression of the next person is not very good, and no one is willing to approach Yu Niang. At that time, Zhang Juzheng's family was very low, and he was proud to work in the family of Zhang Juzheng, the first assistant of the cabinet, so he also cherished this job very much and was very loyal to his master. All the subordinates of the loyal master have more or less opinions on the affairs of the Jade Niang. Yu Niang and Zhang Juzheng are too different in terms of status and age, and if Yu Niang accepts the house, it will not be a good thing for Zhang Juzheng and Zhang Juzheng's family. Especially everyone knows that Mrs. Zhang does not let Zhang Juzheng take a concubine, and Zhang Juzheng will definitely have an opinion with Mrs. Zhang on the matter of Jade Niang. For a concubine, the master's husband and wife are at odds, and this concubine is a vixen. Besides, Yu Niang's life is not good, her mother died when she was a child, and she killed her father and brother not long ago. Just followed Zhang Juzheng, and before he became Zhang Juzheng's official concubine, Zhang Juzheng's father died. Everyone said behind their backs that Yu Niang was a disaster star, and they also resolutely supported Mrs. Zhang's opinion, and did not let Yu Niang enter the door and did not let Yu Niang get close to the master Zhang Juzheng.
