Qin Tai took the portrait drawn by his wife Zhan Xiaoxiao for Zhou's mother, and repeatedly compared it with the descendants of Hanjiazhuang in the archives, hoping to find the similarities inside. Lao Ding, an ordinary old man in the Dongchang archives, also came to take a look, but felt that this woman was not like a descendant of Hanjiazhuang, but like an acquaintance he had seen before. Lao Ding finally told Qin Tai and his wife that he knew the woman in the portrait. Lao Ding recalled this woman while slowly telling Qin Tai and his wife about the history of this woman. This woman's name is Tong Zhou, and she turned out to be the wife of an old neighbor of Lao Ding. Although Lao Ding works in the East Factory, the ordinary people do not know Lao Ding's place of work and the nature of his work, and even Lao Ding does not know that he is in the East Factory. Everyone thinks that Lao Ding is just a certain account man, which is the best way to cover his identity. About more than ten years ago, Lao Ding's neighbor told Lao Ding's family that there was an extra neighbor on the street, and the other party rented Lao Pan's house. This family is not a flat-headed common man, but an official, and the man in the family is a lower-level official of the Ministry of Rites. Soon after, everyone knew that the man of this family was surnamed Tong, the woman was called Tong Zhou, and in addition to the husband and wife, there was a disabled child and an old servant. Lao Ding's family used to be a person who could speak well, so he often went to Tong Zhou's house, and Lao Ding also met Tong Zhou and her husband Tong Liben. That's right, her husband is the famous Tong Liben later, she is the Tong Zhou family who was burned to death in the Tong Liben case that Qin Tai just learned.

After Qin Tai repeatedly confirmed to Lao Ding that Zhou's mother was the Tong Zhou family back then, Qin Tai finally understood Zhou's mother's purpose of coming to Zhang Juzheng's house. Zhou's mother not only really has a problem, but it is really a big problem for Zhang Juzheng's family. Everyone said that it was Zhang Juzheng's system of substitution in kind that forced Tong Liben to death, so Zhang Juzheng was the big enemy of Tong Liben's family. Later, an inexplicable fire not only caused Tong Liben's funeral to be destroyed, but also caused Tong Liben's disabled son to be burned to death at the scene. Even if Tong Zhou's family did not die, this life does not need to be counted on Zhang Juzheng's head, Zhang Juzheng also owes Tong Li's family two lives. Therefore, Zhou's mother wants to enter Zhang Juzheng's house, so Zhou's mother will be able to poison Yuniang and cause chaos within Zhang Juzheng's house. And Qin Tai can be sure that Zhou's mother is not alone, there must be someone behind her or a group of people secretly directing her. Otherwise, it would be impossible for her to hide so deeply, let alone have such a perfect fake identity, and even more so to enter Zhang Juzheng's house. All this was arranged by the people behind the scenes, not only to help her fake her death, but also to let her enter Zhang Juzheng's house with a fake identity and arrange for her to take up important positions, which made her cause internal chaos in Zhang Juzheng's family.

Lao Ding suddenly remembered an incident, his wife once told Lao Ding that Tong Zhou's hands and feet had knife marks, as if he had been seriously injured. Zhan Xiaoxiao immediately remembered the methods of some people in the rivers and lakes, which were the usual methods used by some people in the rivers and lakes to abolish a certain person's martial arts. It seems that this Zhou's mother, Tong Zhou, was once a person in the rivers and lakes, and she was still a person who was abolished by others for her martial arts. Thinking of the results of Hanjiazhuang's descendants, Qin Tai and his wife were even more sure that Zhou's mother was Hanjiazhuang's descendants. The descendants of Hanjiazhuang took advantage of the opportunity of marrying an official as a concubine to escape the pursuit of the people in the rivers and lakes, but they did not live in the official's house for a long time. She took advantage of her eldest wife's jealousy of herself and faked her death while taking away her disabled nephew. She used a fake identity to become Tong Liben's successor, Tong Liben thought that this child was the child born to her late husband, so he was naturally his adopted son. Under the cover of Tong Liben, the descendants of this Hanjiazhuang became Tong Zhou's family, and there was a person who could not be detected by outsiders. If Tong Liben hadn't committed suicide, her origin would not have been discovered by anyone with a heart. The other party used her identity to make a fuss, but she didn't expect that not only did it not succeed, but it caused her nephew to be burned to death by the fire, and the other party rescued her and let her fake her death. Later, under the arrangement of the other party, Tong Zhou entered Zhang Juzheng's hometown as Zhou's mother, and Mrs. Zhang was personally selected to take care of Zhang Juzheng's daily life. Zhou's mother was very interested in Zhang Juzheng's appetite under the arrangement of the other party, and soon became one of Zhang Juzheng's cronies, and while constantly sending information to the other party, she also began to sabotage Zhang Juzheng's home. Poisoning Yu Niang is one, in fact, the person who sent intelligence to report that You Qi has a little wife in the capital may also be her. Even if there is no matter of Zou Yunbiao, the other party's people will find a reason to make trouble in the past few days, and poisoning Yu Niang is to cooperate with the actions of people outside, so that Zhang Juzheng will ignore internal and external troubles.

After determining that Zhou's mother was not only a descendant of Hanjiazhuang, but also Tong Zhou's wife, Qin Tai and his wife decided to arrest Zhou's mother as soon as possible. As a witness and insider, Lao Ding wrote down his testimony by himself, which is the most critical point. Then there is the section where Zhan Xiaoxiao retrieved from the information that the descendants of Hanjiazhuang were abolished by the people in the rivers and lakes on the spot, which confirmed that the injuries on Zhou's mother's hands were caused by the abolition of martial arts, so as to determine that Zhou's mother was the descendant of Hanjiazhuang back then, proving that Zhou's mother had the poison of drunken begonias in her hands. Drunken Begonia is the poison that poisoned Yu Niang, thus proving that Zhou Ma is the real murderer who poisoned Yu Niang. Lao Ding's testimony proves that Zhou's mother is Tong Zhou, the person who is still alive in the world as a fake death. The descendants of Hanjiazhuang, Tong Zhou, who faked his death, proved that Zhou's mother entered Zhang Juzheng's house with an impure purpose, and had a reason to poison Yuniang. With all the reasons for human and material evidence, Zhou's mother can be arrested. By catching Zhou's mother, you can interrogate the main messenger behind the scenes, so as to know who has been targeting Zhang Juzheng, the head of the cabinet, all these years. Although Zhang Juzheng, Feng Bao and others knew very well in their hearts that this person was either Zhang Siwei or Lu Tiaoyang or someone else, they would all need Zhou's mother's confession to confirm this by that time.

Qin Tai and his wife also know that they are not too secretive, so whether this truth can be made public depends on whether Qin Tai and his wife's actions are fast or not. After Qin Tai and his wife asked Lao Ding to send back the file, they immediately took his wife to a safe place and waited for Qin Tai and his wife's summons. While using Qian Laojiu's people who were following behind him, he informed Qiu Xiaoqiu to rush to Xishan to meet Qin Tai and his wife. At this time, Feng Bao's cronies in Dongchang informed Qin Tai and his wife that the carrier pigeon that flew out of Zhang Juzheng's house went to the house of Zhang Siwei, the second assistant to the cabinet, but they did not know the contents of it. Qin Tai was about to come and find Feng Bao immediately, asking Feng Bao to rush to Xishan as soon as possible, telling Feng Bao that there had been major progress in the case and that he needed to talk to Zhang Ju head-on.

However, the cronies of Dongchang who sent a letter to Feng Bao were personally detained by Zhang Jing, the eunuch in charge of Dongchang, shortly after leaving the teahouse. Qian Laojiu's people also went to Qian Laojiu's residence, but they didn't immediately go to Qiu Xiaoqiu. Qian Laojiu was putting on makeup, and he quietly came to the back door of a house and entered the house with a familiar way. If someone can go around the front door, they can find that this family is the house of Zhang Siwei, the second assistant of the cabinet. It turned out that Qian Laojiu had already taken refuge in Zhang Siwei, and Qin Tai and his wife saw Qian Laojiu's personality wrong this time.

Qin Tai and his wife rushed to Xishan, but were stopped at the foot of the mountain. The people who came were not soldiers from the barracks, but several people from different camps. Master Ma of the Criminal Department is an old acquaintance of Qin Tai, and he did not cause trouble for Qin Tai back then. It seems that this time it will not give Qin Tai and his wife a good face. The eunuch Qin Tai and his wife in the East Factory had just met, and he had already taken up the opposite side with Qin Tai and his wife. Jinyiwei came to a thousand-level officer, this person had a sinister face, and he knew at a glance that he was not an easy person to deal with. Behind them there was also an official of the Ministry of Rites, who looked like a civil official of the fifth rank from the dress, and it seemed that he was someone who wanted to suppress Qin Tai in rank.

Qin Tai estimated that the Criminal Department is now under the control of Zhang Siwei, the second assistant of the cabinet, so this Lord Ma should be the person of Zhang Siwei, the second assistant of the cabinet. The Ministry of Rites is directly managed by Zhang Juzheng, but the first two Shangshu are Zhang Siwei, the second assistant of the cabinet, and the current cabinet elder Lu Tiaoyang, so the officials of this Ministry of Rites are either Zhang Siwei's people or Lu Tiaoyang's people. The people in Dongchang are not Feng Bao's cronies, but Zhang Whale's cronies, who came later. It is also very likely that this Jinyi Guard officer was sent by Liu Shouyou, the commander of the Jinyi Guard. None of these people were Zhang Juzheng or Feng Bao's people, and of course the purpose was not to help Qin Tai, but to prevent Qin Tai from going up the mountain to meet Zhang Juzheng.

Qin Tai glanced at his wife Zhan Xiaoxiao, and Zhan Xiaoxiao immediately understood what her husband Qin Tai meant. After a while, they will definitely delay or prevent Qin Tai from going up the mountain, and it is impossible for Qin Tai's ability to break in. The only person who can be killed to find Zhang Juzheng is Zhan Xiaoxiao, when Qin Tai drags these people, Zhan Xiaoxiao kills him alone to see Zhang Juzheng. As long as Zhan Xiaoxiao sees Zhang Juzheng himself, Qin Tai's life will not be in danger. If Zhan Xiaoxiao couldn't see Zhang Juzheng, these people would very likely kill Qin Tai and his wife. So the key this time is Zhan Xiaoxiao, and Zhan Xiaoxiao must complete the task assigned by her husband Qin Tai. Zhang Siwei's people thought that Zhan Xiaoxiao would not leave Qin Tai's side, so they thought that as long as Qin Tai was trapped, Zhan Xiaoxiao would be trapped. Unexpectedly, Qin Tai was already ready to divide his troops with his wife.
