The ancestral hall is located in a remote area. In the past, no one came except the servants who came to clean it. After Tang Min and others entered, they began to search bit by bit. Zhao Xueqian couldn't help but remind them that the poison on the needle might not be completely dried, so they must be careful.

Lu Zheng and Bao Zheng started to search from the northwest corner. After they were away from the crowd, Bao Zheng said with a little worry: "Zhao Shuling seems to be a little different from before."

Lu Zheng looked at him in surprise.

Bao Zheng used a knife to poke the grass while whispering, "I can't tell what's wrong. He almost lost the last skinning case. Many people in the Ministry of Justice laughed at him secretly. He seems not to care, but if he really doesn't care, when Lord Tang told him about this case, he shouldn't have taken the initiative to ask to solve the case for Lord Tang."

"You said, he took the initiative to participate in this case?"

Bao Zheng sighed, "Lord Tang has known him for many years and has always valued his character and talent, so Lord Tang agreed when he said that, but I think something is wrong. But I can't say it. "

Lu Zheng fell into deep thought, and the ominous premonition became more serious. He originally thought that if something happened to the Lu family, it would be impossible to involve the British Duke's Mansion, which had been separated for a long time. However, he underestimated the ancients' care for the family. For example, this time when Zhao Xueqian wanted to perform an autopsy on Lu's body, he went to find the British Duke Lu Qing, and no one thought it was wrong. But in fact, it would be more appropriate to ask the elders of the Lu family or the government to come forward.

Lu Zheng suddenly felt a sense of crisis. Although he didn't know what Zhao Xueqian was going to do, the way to stop him was to find the murderer as soon as possible.

At this time, several detectives shouted, "Sir, we have found something!"

They hurried over and found a needle with the tip pointing upwards in the gap between two tiles. The sharp tip of the needle made people feel cold.

Shihu carefully took out the needle with a handkerchief. This needle was not like an ordinary embroidery needle. It seemed to be thicker.

Tang Min looked at it carefully and said with certainty, "This is the needle that women use to sew insoles."

Using needles and poisoning, if it wasn't deliberately framed, it was almost certain that the murderer was a woman.

Zhao Xueqian seemed to have thought of this, but he did not express his opinion immediately. Instead, he said cautiously: "It's hard to say now. Such needles are not uncommon. Let's start with the source of arsenic."

Tang Min nodded: "Brother Zhao is right."

Since the murder weapon was found in the ancestral hall, it is necessary to check the people who have been in and out of the ancestral hall in recent days. However, since it is not a festival, not many people go to the ancestral hall. Except for a few maids who cleaned the house, only Lu Yuan has been there.

Tang Min and Zhao Xueqian looked at each other: "Check!"

Lu Yuan looked at the people in front of him with a smile: "My lords, the reason why I went to the ancestral hall is because the New Year is coming soon, and I have to prepare all the items for worshiping my ancestors."

"Why should you do this kind of thing yourself? Isn't it better to hand it over to the steward?" Tang Min said suspiciously.

Lu Yuan shook his head: "The worship is related to the fortune of our Lu family for a year. How dare I let the steward do it? Therefore, since I took over the management of the family business, I have done it myself every year and never asked anyone else to do it."

A constable whispered in Tang Min's ear, confirming Lu Yuan's words.

Lu Yuan bowed his hands: "It's busy at the end of the year. If you don't have anything else

to do, I will take my leave first." Zhao Xueqian suddenly asked: "The murderer placed the poison needle on the ground. This trick is vicious and hard to prevent. Since he can use this to harm Master Lu, he can also use the same trick to harm others. Master Lu, don't you think so?"

Lu Yuan's face changed slightly, and he said goodbye and left quickly.

Tang Min looked at his leaving back and said, "Is he feeling guilty?"

"Whether he feels guilty or not, he must know some information." After Zhao Xueqin finished speaking, he said to Lu Zheng, "Master Lu, may I come to visit you?"

Lu Zheng paused and asked vigilantly, "Visit what?"

Zhao Xueqin did not seem to notice his vigilance, and said calmly, "In addition to Master Lu, there is another victim, Lord Lu. Lord Tang and I should also come to visit him out of emotion and reason."

Tang Min smiled and helped, "That's right."

Lu Zheng was very upset, but he could not really stop them, otherwise wouldn't it mean that his eldest brother was injured because of something bad? He was really getting more and more wary of Zhao Xueqian. He might not want to use such a low-level method to frame his elder brother. After all, his elder brother was of noble status and was not as good as Jian Yu. But if he said that he really came to visit for the sake of the case, he would never believe it.

Several people came to the Duke of Ying's mansion, first greeted the old lady, and then paid a visit to the Duke of Ying and his wife, and then went to Feihong Courtyard.

Because Lu Che was bedridden, Pei came out as the hostess to entertain them, but Lu Zheng saw the unhappiness under Pei's gentle smile.

Lu Che was helped out, his face was still pale, but his attitude was impeccable. Although Tang Min and Lu Zheng had a bad relationship, seeing the other in such a sickly state, they felt a little sad.

Zhao Xueqian did not feel that way. After a few rounds of greetings, he asked directly, "Did Lord Lu find any strange people in the ancestral hall that day?"

"No," Lu Che said, "The ancestral hall is very remote. When I and the great uncle went there, there were not even servants to clean it."

"Did you feel anything strange?"

Lu Che thought for a while before saying, "The Japanese officer suddenly felt a little pain in his feet while walking on the road. He thought it was because the stones were not cleaned up. Now I think he might have followed the great uncle's footsteps and stepped on the poisonous needle."

"The weather was so cold that water almost turned to ice. The prisoner put a needle in the crack of the floor tiles and poured water into the crack. The water froze and fixed the needle. After a few days, when the sun came out, the ice would naturally melt away, revealing a tiny needle hidden in the crack. As long as a maid cleaned it, the dust would naturally cover the murder weapon." Zhao Xueqian said, "This plan is so well-planned and flawless. If you hadn't been poisoned, I'm afraid this would have become an unsolved case."

"The net of heaven is vast and long, and nothing can escape it." Lu Che said indifferently, "From what Zhao Shuling said, it seems that the criminal has been found?"

Zhao Xueqin did not comment: "This criminal is not only meticulous, but also knows the whereabouts of Master Lu very well. More importantly, he has great power in the Lu Mansion. - Does Lord Lu have any suspects?"

Lu Che said coldly: "From what Zhao Shuling said, it seems that one of the masters of the Lu Mansion committed the crime?"

Tang Min added: "Lu Yuan did enter the ancestral hall before the incident. Whether he admits it or not, he is the biggest suspect."

Lu Che did not say anything.

Lu Zheng couldn't help but ask, "Do you have any evidence?" He didn't mean to feel sorry for Lu Yuan, although Lu Yuan was indeed the most likely one in terms of motives, but just as Zhao Xueqian had analyzed before, almost all of the masters in the Lu Mansion were suspects, but Lu Yuan had been to the ancestral hall, so this became his most unfavorable factor.

Lu Zheng tried to do psychological profiling, but he always failed. Judging from the arrangement of the case, the criminal should be a person who thinks carefully and makes plans before taking action. However, judging from the implementation of the case, the criminal seemed too impatient and careless. These are two completely different personality traits. How can a person have such contradictory characteristics?

Lu Zheng was very hesitant. He felt that Lu Yuan was not the murderer, but he could not produce strong evidence.

After listening to Zhao Xueqian's words, Tang Min also gave a positive opinion: "As Brother Zhao said, even if it is not Lu Yuan, he must know some clues."

The implication is that Lu Yuan will definitely go to jail.

However, Lu Che's face turned cold: "What do you two mean? You haven't identified the murderer, but you put the second son in jail. How will the world view him? Son killing his father?!"

After he said this, Tang Min hesitated. First of all, they were not sure whether Lu Yuan was the murderer. If he was found out in the end, it would be fine. But if he was not, son killing his father was such a serious crime that it would not only bring shame to the Lu family, but also a great loss of face for the Duke of Ying. Although Tang Min never liked these aristocratic families, he also knew that it would be as easy for these giants to deal with a poor family like him with no foundation as to crush an ant.

Tang Min could ridicule Lu Che and even set traps for him, all because he had the support of Emperor Yongning. But if he really offended the Lu family, even Emperor Yongning would not be able to protect him.

Lu Che's words calmed Tang Min, but did not affect Zhao Xueqian. He looked at Lu Che and said, "Lord Lu, the right and wrong will be judged by the public. Lord Tang is just doing things according to the rules. You are also an official of the Ministry of Justice, you should understand."

Lu Che narrowed his eyes: "What if I don't agree?"

Zhao Xueqian bowed his hands: "If you trust Second Master Lu, you can naturally vouch for him. There is also an article in the criminal law."

This sentence directly put Lu Che in a dilemma. In fact, none of them was sure whether Lu Yuan was innocent. Lu Che wanted to use his power to suppress others, but Zhao Xueqian directly suppressed him with the law. He realized that he had underestimated the other party. He thought he was just a nerd who was familiar with criminal law, but he didn't expect that he was also a good trapper. He actually walked into the trap he set without knowing it.

Lu Che had been an official for many years and had not been plotted against like this for a long time. He smiled coldly: "Zhao Xueqian, you are very good."

"It was the adults who taught me well."

Lu Che was so angry that he swayed. Lu Zheng, who was standing beside him, quickly supported him and patted Lu Che on the back. Then he said to Tang Min loudly: "Sir Tang, I am also an official in the Ministry of Justice now. I think I can also be a guarantor for my second cousin!"

Tang Min finally understood Zhao Xueqian's plan. Before he could get excited and trick Lu Che, he was stunned by Lu Zheng's

brilliant move. Even Zhao Xueqian frowned secretly. Lu Che's expression relaxed and he gave his brother an admiring look. He couldn't show up for this kind of thing, otherwise, no matter whether Lu Yuan was the murderer or not, it would affect his reputation as an official. Zhao Xueqian's move was really vicious, but Lu Zheng's actions simply and rudely disrupted his plan. Anyway, everyone in Yanjing knew what kind of person the third young master of the Duke of Ying's Mansion was. If Lu Yuan was innocent, there would be no impact at all. If Lu Yuan was not innocent, he would just be dismissed from office. This position was obtained by deceiving his brother. He had the ability to deceive his brother the first time, and he had the ability to deceive him the second time.

Previously, he was so angry with Zhao Xueqian that he was at a loss for a moment, but fortunately Lu Zheng was smart.

Although Lu Zheng had no idea what his elder brother was praising him for, he still reflexively puffed out his chest. In fact, he just thought that Lu Yuan was not the murderer, but now it seems that he has also tricked Zhao Xueqian?
