Su Yiyun was stopped outside the dungeon, his handsome face was full of anger: "Your Highness treated the little princess as a murder suspect without any explanation, and now there is no verdict. What? Even visits are not allowed!" The yamen runners

who stopped him were helpless. Although the news of Princess Dai'er's death was blocked, rumors still spread. Otherwise, why would Su Yiyun come to the dungeon so early? But they could only follow the instructions of their superiors and stop him outside. Su

Yiyun talked for a long time, but these yamen runners still did not move. He had no choice but to leave angrily.

Lu Che and Tang Min reported the news of Dai'er's death to Emperor Yongning as soon as possible. Emperor Yongning was furious, but punishing the two would not help. He could only urge them to solve the case as soon as possible and send people to stabilize Su Yiyun.

Lu Che and Tang Min stepped up the search for the murder weapon. If they could find the murder weapon, they could naturally attribute Dai'er's death to suicide. However, they searched all the rooms where Dai'er lived, and even tortured Dai'er's maid, but they could not get any useful clues. As time passed, Su Yiyun's suspicion only grew.

Lu Zheng returned to the scene of Lan Jingyi's death. He did not make any mistakes in the process of Luo Hong's death. Luo Hong's obsessive-compulsive lifestyle was the most important factor that allowed the murderer to perfectly use this killing method. But what about Lan Jingyi?

Lan Jingyi did not have obsessive-compulsive disorder, nor was he nearsighted. If the same method was used to kill him, the success rate would be extremely low. Is it just because he was lucky enough to use the previous method to kill Luo Hong, so he thought he could use the same method to kill Lan Jingyi?

Lu Zheng was a little hesitant. Judging from Luo Hong's case alone, the murderer was bold and careful. Logically, it was impossible for such a person to make such a low-level mistake in Lan Jingyi's case, unless...

"She should want to frame Princess Dai'er." A low and hoarse voice appeared beside Lu Zheng.

Lu Zheng turned his head and found that it was Jian Yu. He was surprised and said, "Why are you here?"

Jian Yu spread his hands and said, "Now the most urgent task is to solve this case, otherwise the trial of the three divisions will not be able to proceed. In this case, I still came to see if you need any help."

Lu Zheng did not think too much, but followed Jian Yu's words and continued, "If you want to frame , the murderer should have many ways instead of using such a circuitous method. What if we hadn't noticed the wound on Lan Jingyi's hand, or didn't even think about going to the roof? Or maybe the petals and pearl buttons fell into some gap and were not discovered?" He shook his head, "The variables of blaming are too great, which is why I didn't think about this at the beginning."

"You are not wrong." Jian Yu said, "But why was Dai'er killed so quickly? If the murderer didn't consider this, how could he react in time? The guards in the dungeon were not lax. If he wasn't prepared, it would not be easy to sneak in and kill people."

"Why do you think he must have killed her?" Lu Zheng asked puzzled.

Jian Yu raised the corners of his lips slightly: "A person who is determined to die will not have such a terrified expression when he dies."

Lu Zheng did not see Dai'er's body, but only heard that she died of poisoning. Hearing Jian Yu say this, he nodded: "If Dai'er did not commit suicide, then this case must have been premeditated, and even the development of the case was calculated by someone. Then I'm afraid that even if we don't find evidence, the murderer will try to point the finger at Dai'er."

"Su Yi Dai'er is the pearl of the Jie royal court and is quite loved by the Jie people. If she dies, the Jie people will be furious and will probably immediately send troops to Daxia." Jian Yu said lightly.

"But what good would it do for the murderer to provoke a war between the two countries?" Lu Zheng guessed, "When the snipe and the clam quarrel, the fisherman

benefits? It's too uncontrollable... Could it be that he has a grudge against us or the Jie people?" Jian Yu replied, "Dai'er died in Daxia for no apparent reason. On the surface, Daxia is in the right, so it's more likely that he has a grudge against Daxia."

"In that case, what does the murderer want?" Lu Zheng bit his finger impatiently.

Jian Yu sighed, pulled his finger out, and wiped it carefully with a handkerchief: "Don't be impatient."

Lu Zheng was stunned for a moment. Jian Yu lowered his head so that he couldn't see the other person's expression, but he still felt uncomfortable. Fortunately, Jian Yu wiped it clean and let go.

Lu Zheng didn't dare to bite his finger again and took a few deep breaths.

"So, back to the beginning, why did Luo Hong and Lan Jingyi die?" Lu Zheng calmed down, "What was the murderer's motive that could make him go to such great lengths to kill two court officials and even provoke a war between the two countries?"

Jian Yu did not say anything, but just let Lu Zheng think quietly.

Lu Zheng's brain was working rapidly, as if he had thought of something. He suddenly turned his head in a daze and looked at Jian Yu: "Is there no one to serve these two people when they fall asleep?"

Jian Yu didn't know what he was going to ask, and sent someone to find Lan Jingyi's servant. The servant nodded: "The master is very clean. He doesn't like people to serve him closely on weekdays, especially when he is sleeping. He doesn't even allow people to stay outside the room."

Lu Zheng fell into deep thought again. When it came to the Luo Hong case before, he also asked the servant about Luo Hong's living habits. Luo Hong didn't like others to serve him closely on weekdays. Even if he spent the night with his wife, he would go back to his room to rest afterwards. It can be said that these two people were alone when they were sleeping. Is this a coincidence or is there any reason?

Lu Zheng had read some books about spies before, which said that these spies were nervous because of the nature of their work and were afraid of revealing secrets in their sleep, so they could only fall asleep when they were alone. But Luo Hong and Lan Jingyi were not spies, and their family backgrounds were clean and there was nothing suspicious about their behavior. So... could it be that they had some secrets that they could not tell others?

Like Lu Zheng, Rong Zhen also thought of this, but his method was much simpler and more brutal. Poor Song Zhiyi was busy like a spinning top, but he was not in vain as the head of intelligence. As long as he had a direction, he would soon find clues.

Luo Hong and Lan Jingyi were both low-ranking officials. Luo Hong was born in a poor family, and although Lan Jingyi was from the Lan family, he was not a direct descendant. The rise of these two people originated from the case of Wei Wang's rebellion twenty years ago. The case of the Huo family, the mother of Wei Wang, was tried. The case file was written by Luo Hong. At that time, Lan Jingyi, as a minister of the Eastern Palace, followed the then crown prince, now Emperor Yongning, when the Huo family was confiscated. After that, Luo Hong rose rapidly, and in just six years he had already become the Minister of the Dali Temple. Lan Jingyi was slightly inferior to him, but with his ability, it was very fast to become the Junior Minister of the Dali Temple in seven years.

Rong Zhen slowly frowned. It was twenty years ago again. Could these two people be related to the things he was investigating?

Song Zhiyi said, "When I was investigating these two people, I found out that Luo Hong and Lan Jingyi have a very good personal relationship, but neither their subordinates nor their family members know much about it."

"Personal relationship?" Rong Zhen tapped the table slowly with his index finger.

"As the saying goes, there are four deepest feelings between men: studying together, fighting together, sharing spoils together, and visiting prostitutes together." Song Zhiyi said with a smile, "But I don't know which one these two are?"

"I have dealt with Lan Jingyi before. He has a bad temper. Even if Luo Hong is his superior, I'm afraid he would not lower himself to make friends with him. Luo Hong is said to be very upright and strict. It's interesting that these two have a good personal relationship." Rong Zhen said slowly, "The earliest intersection between these two was the case of Wei Wang's treason twenty years ago, but I don't know what the mystery of this case is?"

Song Zhiyi said, "If it was about the case of Wei Wang's treason twenty years ago, there were 20 to 30 officials who tried the case at that time, and most of them are in high positions now. Why did the murderer target these two people?"

"What I find strange is why these two people want to stay in the Dali Temple?" Rong Zhen said, "In the 12th year of Yongning, Luo Hong had the opportunity to be transferred to another post, but he refused. In the 13th year of Yongning, Lan Jingyi was appointed as the Shaoqing of the Dali Temple, but at that time he had the opportunity to be the Minister of Works. Although the two positions were of similar rank, the Minister of Works was very old, while Luo Hong, the Minister of the Dali Temple, was young and strong. No matter which one he chose, the opportunity in the Ministry of Works would always be better. Why did Lan Jingyi want to go to the Dali Temple?"

After hearing what he said, Song Zhiyi was puzzled: "It is indeed a bit strange. According to their promotion speed at that time, both of them had the opportunity to go further, but they both stayed in the Dali Temple and did not leave. What on earth is there in the Dali Temple that makes them reluctant to leave?"

"Reluctant?" Rong Zhen shook his head, "Not necessarily."

"What does my cousin mean?"

"I think these two people dare not leave the Dali Temple." Rong Zhen lowered his eyes, "This fear even suppressed their desire for power. This may be related to the secret these two people have kept together."

"What secret?"

Rong Zhen said lightly: "If I knew, I would ask Zhi Shu to catch the murderer now. What's the use of telling you all this?"

"Ahem..." Song Zhiyi touched his nose, "Then what should we do now?"

Rong Zhen stood up, thought for a long time, and then spoke slowly.

"Send a message to Su Dai, asking him to count the food and grass, intensify the training, tighten the city inside and loosen the outside, and immediately arrest any suspicious person. In addition, call back all the Night Owls and prepare for the battle."

Song Zhiyi was refreshed. The Night Owls were the intelligence organization under his charge. They were originally prepared for the battle in Northern Xinjiang, but Northern Xinjiang was frightened by Rong Zhen in recent years. The Night Owls were gradually dispersed to various places and hidden among the crowd. Now with Rong Zhen's order, it means that a big war is about to break out.

"Yes!" Song Zhiyi took the order and left.

Rong Zhen looked out the window. The setting sun was as red as blood, hanging in the dark night sky, faintly indicating the unknown.
