"This incident shocked me, so I ordered Xue Bi to adjust the files of the case recorded by Qianji Office. When I carefully searched, I found that Dou Jue and Ning Zheng had stayed in the eastern suburbs, and Deng's family also had some people stationed in the Minzhuang Mountains in the eastern suburbs. But Fu could not find any trace. Later, Xue Bi found a suspicion in the bandits who came out of the mountain to intercept Dou Xunen. He specially searched people to find out the origin of these bandits everywhere. Finally, he found that these bandits came from the Shuangsha Gang. They were the father of Prince Hengye, a wealthy subordinate."

"The Fu family, Deng family and Dou family have joined forces with Ning Zheng to get rid of Dou Xunen? Why is this?" Mu Yun said dumbfounded, "Dou Xunen... What did the Dou family Sanlang do that actually led to the three great gentry collusion with Ning Zheng and put him to death?"

Jiang Chengyi frowned and said, "It's this strange thing. A few days ago, I went to Siyinfang in person and read the records of all kinds of strange things that happened in the Great Wei Dynasty at the end of the third year of Yongning, but I didn't find anything."

"I have a question." Mu Yun said strangely: "Dou Xunen...is not Dou Jue's parent-child? Why did Zuo Fengyi Duke Dou Jue join forces with outsiders to kill his parent-child?"

Jiang Chengyi was stunned. These days, he had been investigating the connection between Fu and the incident that year, and ignored such shocking suspicion.

Yes, Dou Xunen is the most outstanding among the Dou family's children, and Duke Zuo Fengyi favored him the most. How could such an enviable father-son relationship reach the end of the road?

The tiger poison is still not a child, let alone Dou Xunen, the youngest son Dou Jue is extremely beloved?

He pondered for a moment, his expression became heavy: "These days, my attention has been on the Fu family and his son, and I have never paid attention to the fact that Dou Jue was also in the eastern suburbs. Perhaps the investigation direction of this case was wrong from the beginning."

As he spoke, he became murmured to himself. After a moment of thinking, he immediately lifted the curtain of the car and said to Xue Qing, who was driving the car outside, and said, "A Qing, don't go back to the mansion first. Take a detour and change your clothes and disguise. Let's go to Siyinfang."

Xue Qing was caught off guard by his sudden order to change the route, and was stunned for a while before responding: "Here."

But Mu Yun said suspiciously: "Why are you going to Siyinfang at this time? It's already dark now."

Jiang Chengyi said: "Let's check all the files entered by Qianji Department back then, and only look at the Dou family, and maybe they can find any clues."

Mu Yun said again: "Your injury... can withstand the tossing?"

Jiang Chengyi knocked his white lips and said, "My injuries are fine. It's not a knife or a sword. Now it's winter in Luoyang. The wound will not get inflamed, so I can still hold on for a while."

He insisted on doing this, and Mu Yun knew that it would be useless to persuade him more, so he simply refused. It would be better to have her accompany him to untidy the knot of this matter and let him rest in the mansion.

Xue Qing drove the ox cart into an ordinary alley. With the help of Mu Yun, Jiang Chengyi quietly went to a dilapidated thatched hut.

Xue Qing took down the casual clothes and leather masks he had always kept in the car, and then hurriedly entered the room after exploring left and right.

"The lord and the daughter are dressed up here. The subordinates are guarding near the hut and watching the wind. If there is anything wrong, they will come and tell them immediately." Xue Qing said.

Jiang Chengyi nodded, took the clothes and mask he handed over, and changed into clothes with Mu Yun in the house.

After a while, the three of them came out of the hut again, and they had completely changed their appearance.

Mu Yun and Jiang Chengyi disguised themselves as an old couple, bent over and supported each other and walked slowly forward. Xue Qingyi pretended to be another look and followed them.

The three of them walked around the corridor of the alley and headed to the east gate Piyun Lane.

The sky was dark and there were few pedestrians on the road. Most of the people in Luocheng were playing in the Huajie Market at this time.

Seeing that there was no one around, Xue Qing took Jiang Chengyi and Mu Yun and quickly slipped in from the side door of Siyinfang.

The guards guarding here rushed over immediately when they saw something was wrong with the side door.

The four guards faced each other with swords, and Xue Qing immediately took out his waist card to prove their identity.

The guards guarding the side door repeatedly confirmed twice before letting them go.

Jiang Chengjia was familiar with the road and walked towards the wing room on the right.

After arriving at a safe place, he tore off the mask stuck to his face and took a breath. The scorching pain behind him made him feel palpitations again, making his face look even more ugly.

Xue Qing went to find the fourth uncle in the room and Yan Ji. Jiang Chengyi sat in the house with Mu Yun and waited.

While they were waiting, they thought carefully about the abnormalities of Dou Xunen.

Soon, Mu Yun asked again: "Ayi, you came to Siyinfang a few days ago. Didn't you notice anything abnormal about Dou's family in the end of Yongning in the third year?"

Jiang Chengyi was stunned and looked at the memories in his mind and said, "At the end of the third year of Yongning, Dou Jue served as the head of the East Prefecture Department because of Dou Jue... It has been smooth sailing and there is no abnormality. So... I think it must be that I missed something. Then I want to check the files of that year again."

Mu Yun said, "Maybe...we shouldn't start from the end of the third year of Yongning."

Jiang Chengyi calmed down, lowered his head, and after pondering for a moment, he said, "You mean, maybe we should check the files stored in Qianjiyuan in the year that Dou Xunen was born?"

Mu Yun spread his eyebrows and nodded, "That's what I mean. Since you have read the files from Yongning at the end of the third year, but have not found anything, it means that Qianji Chu did not record any useful clues. Dou Jue suddenly killed his biological son, which is surprising. What's more, Dou Xunen, who is extremely beloved? No matter what, Dou Jue, as a father, will not bear to kill this killer. Unless... Dou Xunen touched the interests of the entire Dou clan for his own private purposes, Dou Jue can only destroy his relatives for justice."

"Or..." Jiang Chengyi paused, "Dou Xunen is not Dou Jue's parent-child. He was carrying Dou's shocking secrets, forcing Dou Jue to join forces with King Huai to kill him."

Mu Yun pursed the corners of his lips and expressed his approval with silence.

After about half an incense stick, Xue Qing took Uncle Fang Si and Yan Ji to the wing room.

Uncle Fang Si stood in front of Jiang Chengyi. This was an old man with a bright hair. Although he was in his sixties, he was still energetic. His handsome appearance was still vaguely revealed on his positive face.

Yan Jisheng is charming and versatile. She is wearing a cicada wing gauze and is wrapped in a half-shirt and robe. She faintly reveals her proud figure, covering her veil, revealing a pair of beautiful eyes with autumn waves. The charming power of soul-catching charm makes people want to approach her.

The two were about to salute Jiang Chengyi, but they saw him wave his hand and said anxiously: "I have to bother with Uncle Fourth and Yan Ji to find out the files recorded by Qianjiyuan in the year of Yongchu..."

Listening to Jiang Chengyi's instructions, he did not want to ask too much, but just obeyed, bowed slightly to him, and took Yan Ji to the screen on the other side of the house.

Behind the mica screen, there was a shelf made of pear wood, with many ancient books and antiques placed on it. Uncle Fang Si was fumbled in the pile of ancient scrolls for a while and stopped. He held a roll of ancient scrolls in the center, lifted it up gently, and gently pulled out a silver thread from the pile of ancient books.

He used some force, and the pear wood carved shelf that was close to the wall was divided into two halves from the middle, and a gap appeared on the tiled wall at the back slowly opened to the right.

There is a secret room in the wing room, which stores another file recorded here by Qianjiji.

Looking around, there were bookshelfs several meters long in the secret room, covering the entire room. Various boxes and scrolls were placed on the shelves.

Xue Qing and the fourth uncle Yan Ji were searching in the secret room together.

Jiang Chengyi was waiting outside, and although the anxiety in his heart had never appeared on his face. But Mu Yun knew him and knew that he was rubbing his fists and palms at the moment and wanted to know the truth. So he stretched out his hand and patted him gently on the back of his hand, comforting him, "Don't worry... I'll look for it with you today."

He looked at Mu Yun, suppressed the inexplicable tension, and took a deep breath and said, "Okay."

Why was he anxious? In addition to finding out the truth about the incident back then, he also wanted to find out the evidence from this clue that Fu Boming Hengye's son detonated the private prison of Deng's man. He had selfish intentions and wanted to protect Qin Ye. Although he knew that this matter would not have caused such a disaster without Qin Ye's control, he still wanted to prove that Qin Ye was not the ultimate culprit of the private prison explosion.

After about two cups of tea, Xue Qing, Uncle Fang Si and Yan Ji walked out of the dark room with a stack of files in their arms.

The three of them left the secret room, and the brick walls and pear wooden frames that implied the mechanism were slowly closed.

"Young Master...there are so many files in Yongchu in the year... Are you sure you want to read them one by one?" Xue Qing looked at the books piled up in mountains on the table and said frowningly.

Jiang Chengyi said with a tough bullet: "Even if there are more, today... we need to find some clues from it. It is not just the files from the year of Yongchu, but also the books from the end of the year of Yongning. Maybe we will check them carefully."

Uncle Fang Si looked gloomy and stared at the books and asked, "What are you looking for?"

"The year of Yongchu was when Dou Xunen was born. The household registration records show that Dou Xunen was born in September. Since this is the case, he took September as a line and carefully checked what was unusually strange about Dou and his children and their students back then." Jiang Chengyi gave a few simple instructions.

Uncle Fang Si nodded, picked up a book piled on the table table and started to check it out.

The five people gathered together, from reading in the evening, lighting the lamp to reading, until the night was dark, they had not stopped.

Hundreds of volumes made them look awkward in their eyes and their backs sore.

The servant under the fourth uncle made some snacks and brought them to him as Xue Qing's instructions.

Several people used some snacks and continued to read them again.

After a while, Yan Ji, who had been silent, found something unusual from the case file she was holding.

"On the fifth day of the ninth lunar month of the year of Yongchu...When Dou Xunen was born, how did Dou Yue, the sister of Zuo Fengyi, Dou Jue, be assassinated and died outside?" She murmured to herself and was heard by Jiang Chengyi.
