Chu Yunfei needed to talk to Mrs. Xiang seriously, while at the same time, Ye Huan and Mei Yingxue hurried to Mrs. Xiang's house to continue the investigation. Leaving Mrs. Xiang here and buying time for Ye Huan and Mei Yingxue as much as possible was Chu Yunfei's arrangement. The only thing that surprised Chu Yunfei was that Mrs. Xiang was very smart, and she quickly guessed Chu Yunfei's intentions.

"Why waste time? Childe is a smart person, why don't you just say what you mean? I won't hold you back. With a shallow smile, Mrs. Xiang continued: "I should have guessed a long time ago, since Song'er is in trouble, I naturally can't escape as an elder. That girl...... I didn't expect to escape from the palace, I was supposed to not let her enter the mansion, but she likes Song'er so much, I can only turn a blind eye. But Chu Gongzi, you are a person in the public family, and you always have to talk about evidence when investigating cases. If she died, do you have to blame us? Don't you think that's unfair? Whether Song'er is innocent or not, I dare not say, after all, young people are always impulsive, but you can't pull our whole family into the water, right? We are people who have dealings with people in the officialdom, if there is any rumor, should I do my business? ”

"Isn't Madame Xiang's reaction too intense?" Chu Yunfei laughed, Mrs. Xiang had become less calm, and even a little impatient. Did it poke her in the sore spot? She obviously wanted to get rid of Luo Wensong, and if she could, she would not hesitate to completely dissociate herself from Luo Wensong.

The corners of Mrs. Xiang's mouth curved upward, but there was not the slightest smile on her face: "Intense? Is this still called intense? Now that someone is dead, I don't know how many pairs of eyes are waiting to see our jokes? ”

"It's just a formality. Could it be that Madame is weak-hearted? Or did you hear something, that's why you asked? Chu Yunfei continued to ask.

Mrs. Xiang didn't say anything more, but laughed, "Young Master Chu, if you didn't suspect anything, you wouldn't send that Mei Gongzi to our house, right?" Isn't inviting me here a delaying tactic? Mei Gongzi ...... It's your best friend, and you've been almost inseparable from him since you started investigating crimes. Everyone says you're a world-famous detective, but without this assistant, you might not have achieved so much, right? Plus Ye Huan, that is, your fellow disciple...... Even if there is nothing, I'm afraid we don't want to clear our suspicions. You...... What a good hand. But I'm sure you can't find out anything, because we didn't do anything. Do you want to find out something from where she lives? I advise you not to waste your efforts. ”

It's time to do your trick. Chu Yunfei took a sip of tea, still with a faint smile on his face, and said, "Everything may be more complicated than we imagined. Actually, they asked me to go for me, not to see what you wanted me to see, but to find a room, a room that you can't change yet, or that you can't change yet. ”

"Oh?" Mrs. Xiang looked at Chu Yunfei with her hands on her cheeks, as if she was very interested in what he said, but her fingers were already trembling slightly, "I don't understand anymore." ”

Chu Yunfei said lightly: "We have carefully checked Lingyan...... That is, the body of Luo Wensong's lover, who was found to have died of poisoning. But the strange thing is that it is not food poisoning, but the accumulation of poison in the body to a certain extent, and it is induced by external factors. Miss Lingyan is actually a very smart person, maybe Luo Wensong's pursuit has made her confused, but when she finds out Luo Wensong's true identity, she must have doubts. Since Luo Wensong wanted to use her to do something, and also to frame the Pan family, he could only arrange that plan more carefully, maybe that plan had been quietly carried out long before she was brought to your house. ”

"I still don't quite understand." Mrs. Xiang's expression was very ugly, she blinked her eyes several times, then wiped her eyes with a handkerchief, sighed and said, "I have heard some rumors, I heard that you will do whatever it takes to achieve your goals. You wouldn't deliberately frame him in order to please the palace, would you? ”

This is a sign of weakness of mind. Chu Yunfei could feel that Mrs. Xiang's emotions were on the verge of collapse, but he didn't quite know why. It was time to stimulate her nerves. Chu Yunfei glanced at her and shook his head calmly: "What I am best at is solving mysteries. But the person who committed the crime this time is really extremely smart. There are many ways to poison and not be noticeable, and it is almost impossible, but for smart people, it is relatively simple, for example...... Doing ...... on window paper and furniture"

The cup in Mrs. Xiang's hand fell to the ground suddenly, and she wanted to hide something, but it was obviously too late. Next, she could only pretend to be calm and instructed the maids to clean up the broken cups, and then wrote lightly: "Don't misunderstand, childe, I'm ...... Frightened by your words. Would anyone really have thought of using it in such a way? Pine ...... He's not that kind of person, he's good-natured. Besides, looking at your attitude, you should know that I have a past with the Chai family, and the Chai family has never done anything to achieve their goals, and this time will be no exception. Please ......."

"These are just my conjectures, and I still need proof." Chu Yunfei was silent after saying this. In fact, Mrs. Xiang's attitude has confirmed that his conjecture is correct. All he had to do was wait. And Mrs. Xiang is unlikely to leave on her own initiative, whether it is to find out the news or for her own innocence.

Of course, Mei Yingxue and Ye Huan couldn't disappoint Chu Yunfei, and what they brought back confirmed Chu Yunfei's speculation: in the hidden backyard of the Xiang family, they found a guest room that had been tampered with: those houses were too easy to identify, because only the three houses connected together were made of papier-mâché windows. One of them was Lingyan's house, and the clothes that Lingyan had worn after leaving the palace were found inside. Ye Huan carefully inspected and found that the window paper, screens, beds and even the tents on the bed had been tampered with, and all those things had been smeared or soaked in arsenic. As Chu Yunfei expected, there was a pond in front of the house, and the stove was raised in the next room, which seemed to belong to Lingyan's small kitchen. The moisture of the pond accelerates the decay of the window paper, and the stove raises the temperature of the room, which is conducive to the slow evaporation of arsenic soaked in the object. Over time, those toxins were slowly absorbed by Lingyan.
