When Lu Zheng returned to the Duke of Yingguo's mansion, he found that everyone in the mansion was in high spirits, even Yun's expression was particularly cheerful. He asked Liu Zhi with some surprise: "What good thing happened today?"

Liu Zhi said helplessly: "Young Master, you forgot that the second young lady and the aunt will arrive in these few days, and people are waiting at the dock every day."

Lu Zheng then realized that Lu Wanxin and her family would indeed arrive after the New Year, and it would be about this time if you calculate the time.

In addition to Lu Wanxin's return to her parents' home three times, this is probably the second time she has returned home in these years. No wonder the whole family is so looking forward to it. In Lu Zheng's memory, this second sister is very good to him. He is now more and more into the identity of the third young master of the Duke of Yingguo's mansion, not to mention that Lu Wanxin's two children will also be homeschooled. Compared with Lu Zheng who is now isolated in homeschooling, he is indeed looking forward to it.

Lu Zheng thought for a moment and said to Liu Zhi, "I have to prepare some gifts for my nephew and niece."

Liu Zhi smiled and said, "I have prepared them a long time ago, just waiting for you to come and see them one day."

"I trust Liu Zhi to do things." Lu Zheng said with a smile.

Ji Xiang, who was just coming in from the gate, happened to hear this, but seemed to have heard nothing and put the snacks on the table: "Master, the eldest master asked you to go to Feihong Courtyard when you are free."

"Oh." Lu Zheng stood up quickly, "Then I will go over first, you can have the snacks."

After saying that, he left in a hurry.

When Lu Zheng arrived at Feihong Court, Lu Che was just about to go out. Seeing his brother coming, he relaxed his brows and said, "You're just in time. I was just about to ask someone to urge you."

"What's the matter, brother?"

"Another case." Lu Che rubbed his brows, his face looking a little ugly. "Dali Temple Chief Luo Hong was found dead in his room this morning."

Lu Zheng was stunned. He never thought that the three courts would have reviewed the case until now. The prisoner who was protected by layers of protection was fine, but the official who was trying the case was killed.

Lu Che's headaches did not end there. Because of Rong Zhen's concession, Lu Che wanted to show off his skills during this three-department trial. He had a good relationship with Luo Hong and had reached a consensus long ago. However, after Luo Hong's death, not only was the three-department trial suspended, but it was also a problem as to who would take over as the Dali Temple Minister.

In the court, Emperor Yongning also had an ugly face and ordered the Ministry of Justice and Jingzhao Prefecture to solve the case as soon as possible.

Tang Min was also depressed. It had only been a short time since the skinning case. He had been unlucky in the past few years and could not care about the conflict between him and Lu Che. If this case could not be solved, he was afraid that his position as Jingzhao Yin would be over.

The crime scene was in Luo Hong's study. Luo Hong had a cold temper and was busy with official business, so he often stayed alone in the study. He did not go back to the master bedroom to rest last night, and his family members were used to it. However, he was still not seen at breakfast. Mrs. Luo felt strange, so she sent her eldest son Luo Wei to the study to call him.

Luo Wei opened the study door and found Luo Hong sitting at the desk. He asked several times but there was no response. When he got closer, he found that Luo Hong's body was already cold. He was so scared that he crawled to report the case.

Lu Zheng followed his eldest brother to the study of the Luo Mansion. Luo Hong's body had already been placed on the couch in the study. Shihu was performing an autopsy, and Tang Min was asking Luo Wei about the incident.

Lowe wiped his tears and said, "…My father always gets up early. My mother didn't see him at breakfast and was a little surprised. She thought he was lazy and slept a lot, so she asked me to call him. I went to the study and found the door was closed. I knocked but there was no response. I pushed it and found it was locked from the inside. I was worried that something happened to my father, so I asked two servants to break the door open and go in. When I got there, I found my father sitting at the desk with his head down. I called him a few more times, but he didn't respond. I took a closer look and found that he had died a long time ago..."

Tang Min asked, "Is the study door locked from the inside?"

Luo Wei nodded, "Yes, my father is cautious by nature, and he never keeps anyone to serve in the study. Every time he works in the study, the door is locked from the inside."

"Did you find anything strange after you went in? For example, was anything moved?"

Luo Wei recalled carefully, then shook his head affirmatively: "No."

Tang Min was not discouraged: "Think about it again, think it through before you speak."

"My father's things are always neatly arranged, and it's easy to see if something is missing."

Tang Min asked some more detailed questions until there was nothing left to ask. The clerk next to him showed Luo Wei the written testimony, and after confirming that it was correct, he asked him to sign it.

Tang Min frowned and walked towards Lu Che and the others.

"Did Lord Tang find anything?" Lu Che asked.

"There is nothing, nothing was dropped, the doors and windows were tightly closed, there was no one else in the room except Lord Luo, it is impossible that he committed suicide!" Tang Min said unhappily.

Lu Che followed his gaze and saw Lu Zheng walking to Shihu: "What's wrong?"

Shihu shook his head: "Very strange."

"How is it strange?" Lu Che and Tang Min also walked over.

Shihu pointed at the wound on Luo Hong's neck and said, "Lord Luo has only this one wound. The edge of the wound is smooth, like a narrow bladed weapon. However, no matter what weapon, the wound should be a straight line, but Lord Luo's wound is slanted."

Lu Zheng also looked at the wound carefully. It looked like a U-shaped red line encircling Luo Hong's neck.

Shihu said again, "Such marks are usually seen in strangulation, and the bloodstains are almost all spurting downwards, which means that the murderer should be standing behind Lord Luo and killed him with a weapon similar to a soft sword or a steel cable."

"Behind?" Tang Min muttered, standing behind the desk. If Luo Hong was sitting, the murderer standing behind him could indeed have caused such a wound. But the problem now is that the doors and windows of the house are closed, the constables did not find footprints or anything like that in the room, and nothing in the room was lost.

Lu Zheng walked around the study room, and everything in the study room was neatly arranged, the books were sorted, the pens on the pen holder were arranged according to length, and except for an open document on the desk, everything else was stacked and placed aside.

Lu Zheng felt that this Lord Luo Hongluo was simply like a patient with obsessive-compulsive disorder, and the information he got from Luo Wei also made him sure of this point, that Lord Luo was not only a patient with obsessive-compulsive disorder, but also a perfectionist.

And this house was like a perfect secret room.

Luo Hong's case was temporarily at a standstill, and Rong Zhen also received the news. He looked at the case from another perspective: "Luo Hong is a low-key person with a good reputation as an official. He has no intersection with any forces. If the murderer wants to disrupt this three-court trial, it shouldn't start with him."

Song Zhiyi said: "I heard that Luo Hong and Lu Che have a good personal relationship."

"You said the murderer's target is the Duke of Ying's Mansion?" Rong Zhen shook his head, "It's unlikely. The difficulty of killing Luo Hong and killing Lu Che is not much different. If the murderer's target is the Duke of Ying's Mansion, why would he take such a big detour."

"Could it be a personal vendetta?" Song Zhiyi guessed.

Rong Zhen tapped the tabletop lightly with his index finger: "It is also possible that Luo Hong blocked someone's way."

"Once Luo Hong dies, the most likely person to take over as the Chief Justice of the Dali Temple is his deputy Lan Jingyi."

"Lan family?"

Song Zhiyi shook his fan: "The Lan family was also a member of the Wei Wang faction more than 20 years ago, but the Lan family was luckier than the Gao family. The head of the Lan family cut off his wrist in time and saved the family. However, the Lan family fell into silence because of this. I am afraid that Lan Jingyi is the highest-ranking official in the Lan family now."

"This is interesting." Rong Zhen raised his eyebrows, "Recently, people related to the old events of 20 years ago have appeared one after another, as if someone did it on purpose."

"You suspect..."

"Twenty years ago, the last trace of the King of Wei was in Baiquan Mountain. The officers and soldiers who were chasing him said that he fell off a cliff, but my brother has sent people to look for him for so many years, but his body has not been found." Rong Zhen narrowed his eyes, "He was praised by my father for his courage and wisdom. I don't believe he would die so easily."

"But even if he didn't die, would he want to rebel again?" Song Zhiyi asked in disbelief.

Rong Zhen shook his head: "I also met this Prince of Wei in the past. He was as beautiful as a lily and jade tree, and being with him was like being bathed in spring breeze. Even after so many years, I still can't forget it. How could such a person rebel just like that?"

"Could it be..."

"The past cannot be verified." Rong Zhen sighed, "Let's look at the current situation first. Once Luo Hong dies, the eldest prince and the fourth prince will probably fight for the title of Dali Temple Minister. If the Lan family really wants this position, they will definitely not do nothing."

Song Zhiyi smiled and said, "Cousin, you should not worry about Lan Jingyi for now. I see that the carriage behind looks like Princess Dai'er's."

Rong Zhen frowned and said, "Zhishu!"

Nie Zhishu walked into the pavilion. After glancing at Song Zhiyi, he said respectfully: "Master, don't worry. The secret guards have prepared a fake carriage and will definitely deceive Princess Dai'er."

Rong Zhen looked at Song Zhiyi, who was gloating over the misfortune, and suddenly smiled: "If you want to do it, you had better make it more realistic. How can there be no one in the carriage?"

Song Zhiyi felt a chill on his back. Rong Zhen gave the order very naturally: "Change Lord Song's appearance. Cousin, your voice-changing skill caused me a lot of blame back then. I hope you won't let me down this time."

"I'm wrong, cousin! Cousin!"

Song Zhiyi howled as he was taken away by the secret guards.

The master and servant in the pavilion seemed not to have heard anything. Nie Zhishu continued to report: "General Su sent a message that the second prince of the Jie people has unknowingly controlled most of the troops, and the other princes were killed by him on charges of treason. Not long after the sixth prince entered the capital, he took over the position of the Great Khan."

"It seems that we have all been fooled by this sleight of hand." Rong Zhen said lightly, "Su Yiyun Ge had already surrendered to Su Yi Wuya a long time ago. If he hadn't attracted most of our attention, I'm afraid Wuya wouldn't have seized the position of the Great Khan so easily."

"Master, what should we do now?"

"Don't worry, Su Yiyun Ge's purpose in coming to Beijing is not just this. Wait, the jackal will always show its fangs. It should look at its prey before pulling out its teeth."
