The three of them entered Liu Yan's house.

Ming Yihan checked everywhere, but Du Nianqing kept standing at the door, Zhou Qifeng came out of Liu Yan's room carefully and walked to Du Nianqing's side, "What are you looking at?" ”

Du Nianqing pointed to the loose marks of the broken door frame and said, "I suspect that the person should have hit the door in a panic when he left, and a nail fell on the ground." ”

Zhou Qifeng fixed his eyes and saw that a nail had indeed fallen on the ground, he squatted down to pick up the nail, Du Nianqing stared at the door again, and stretched out his hand to imitate it, if the man fled in a hurry after poisoning Liu Yan, when he hit the door, his hand would definitely subconsciously touch the door, and there would definitely be a palm print on the door, but it is still difficult to detect fingerprints with the current case-solving technology.

"I walked around inside and found half a pack of arsenic hidden under the boiler." Ming Yihan wore white gloves and took out the paper bag stained with furnace ash.

Du Nianqing raised his eyebrows, this guy even wore gloves?

"Arsenic? However, at the time of the autopsy, the poison in the deceased was not arsenic. Zhou Qifeng frowned and took the arsenic from his hand.

"This should have been kept by Liu Yan herself, and it has been hidden below for some years."

Du Nianqing asked: "Then how was Liu Yan poisoned?" ”

Zhou Qifeng stated: "Aconite, it was the murderer who injected aconitum juice into her body. ”

"Injection?"

"Hmm."

"Can the average person get a syringe?" Du Nianqing asked.

Ming Yihan answered: "He should have taken the opportunity to pick up a batch of syringes when he was handling a batch of syringes in the hospital, this kind of person must be staying near the hospital and knows the environment near the hospital very well." ”

Both of them felt that there was some truth in Ming Yihan's words, and he continued: "It's just that I don't understand why Liu Yan kept half a bag of arsenic, is she planning to commit suicide or kill someone?" ”

Du Nianqing condensed his eyebrows and thought, Zhou Qifeng suddenly thought of something, he said: "Liu Yan's autopsy report recorded that she contained arsenic in her body, and Sun Furong's autopsy report also recorded that she contained a small amount of arsenic in her body. ”

Du Nianqing raised her eyes in astonishment, she suddenly understood, she looked at Ming Yihan, and she was also a little puzzled: "So to say that their mother and daughter have been consuming arsenide for so many years?" But why? Liu Yan has been putting arsenic in food, does Sun Furong know? What was her purpose in doing this? ”

"These connections have to be found out in order to know, and at present, maybe as long as the murderer is caught, he can solve the puzzle, he must know the truth of the year."

Before leaving, the three of them went to the tomb of the destroyed Sun Furong to observe for a while.

After that, Ming Yihan proposed to go to the cemetery again, and when he went to the cemetery, Sun Furong's monument was being dug up by four workers, and the three of them stepped forward, Du Nianqing asked: "What are you doing here?" ”

The workers looked at the visitors, looked at them carefully, and said, "A young lady has ordered us to dig this grave." ”

Du Nianqing asked again: "A young lady?" Is it convenient to say who it is? ”

Could it be that the tombstone in this cemetery was built by her for Sun Furong?

"I'm sorry, miss, we can't reveal who the employer is."

Du Nianqing didn't continue to ask, she glanced at the tombstone next to her, there were a few bouquets of flowers in front of the monument, she had noticed this tombstone before, there were always people sending flowers in front of the monument, someone cleaning, she was still thinking about which rich and noble family it might be.

She went to see the name on the tablet, and let out a sound in surprise, the eyes of several people looked at her at the same time, Ming Yihan and Zhou Qifeng walked up to her and asked, "What's wrong with you?" ”

Du Nianqing's eyes widened, "Cheng Dieqing?!" ”

"What's wrong with Cheng Dieqing?" Ming Yihan glanced at the name on the tablet and looked at her with frowns.

Du Nianqing slowly looked back at him: "This is Cheng Dieyue's sister!" ”

She listened to Du Linzhi talk about what happened to Cheng Dieqing, could it be that this tombstone was built by the Du family for Cheng Dieqing?

Ming Yihan asked, "So what's the matter?" ”

Zhou Qifeng said coldly: "This Miss Cheng used to be with Young Master Ming. ”

“？？？”

Du Nianqing's face is full of black question marks, she is a Buddha, how can she still have such a past?

Du Nianqing gossiped: "Really fake? ”

She hadn't heard Du Linzhi mention this.

"Really." Ming Yihan said: "But because Cheng Dieqing was a maid taken in by the Du family at that time, and after the old man knew about it, he strongly opposed it, and even threatened Ming Yihe with Cheng Dieqing's life, so it didn't take long to break it." ”

"You know?"

"Of course, I'm not from the Ming family, am I?" Mingyi glanced at her.

Du Nianqing suddenly felt that the relationship between the several families was so chaotic, as if they were all connected, and he felt that he looked at the well water and did not interfere with the river water on weekdays, and nodded his head.

When he went back, Du Nianqing suddenly felt a very bold idea pop up in his mind, "Do you think Sun Furong will like Ming Yihe?" ”

Ming Yihan asked, "How did you have such thoughts?" ”

"I don't know, my intuition tells me that the more I know now, the more confused my mind becomes, maybe this is what confuses us, in fact, many real thoughts may not be as complicated as we think."

This is the same as the most dangerous place is often the safest place, sometimes the more complicated it is, it may just be a trick, as long as you really grasp a point, you may be able to solve the problem.

Ming Yihan smiled: "There's nothing wrong with you thinking so, but you're wrong, Ming Yixuan told me last night that Liu Yan went to him just to tell him something, but in the end he only said that Sun Furong likes my father." ”

"Uh, can I say I actually doubted that before?" Du Nianqing pursed her lips, she actually thought so at first, she thought that Ming Shengtang and Sun Furong might be in love, but since Ming Shengtang talked to her last night, from his words, she could hear that the person he liked in his heart had always been Ming Yihan's mother, Yang Yun.

"Then why do you think Sun Furong likes Ming Yihe again?" Ming Yihan asked.

Du Nianqing thought for a while, "Intuitively, but I think Ming Yihe may not like Sun Furong." ”

Ming Yihe hasn't married a wife at his age now, maybe it's because of Cheng Dieqing? Then he should also know where the tombstone was built after Cheng Dieqing's death, if he came to worship, he would definitely notice Sun Furong's tombstone next to him, but although it was damaged, he never found someone to repair it, which is enough to prove that in Ming Yihe's heart, Sun Furong is a person who is not even a friend.

"But then again, Ming Yihe likes Cheng Dieqing, no wonder he took so much care of Cheng Dieyue when he was in Luojing Town."

"You have a mouthful of Ming Yihe, why do I think you are very worried about him?" Ming Yihan frowned and glanced at her.

Du Nianqing rolled her eyes, "How can you worry?" Isn't this discussing the relationship between him, Cheng Dieqing, and Sun Furong? Just take matters into account! ”

"Hmph."

Zhou Qifeng returned to the police department, Zeng Yunlong also happened to come back from outside, and after meeting, Zhou Qifeng asked, "How is the progress of the matter I asked you to investigate?" ”

Zeng Yunlong shook his head, "There is no progress, our people are squatting around, and we haven't found any suspicious characters who meet the requirements, but there are a few rickshaw drivers who pull the cart are wearing lotus hats, but we can't arrest all the people who wear lotus hats for interrogation without any evidence, right?" ”

Rickshaw driver? Why didn't he think of it in the first place? Maybe the murderer is a rickshaw driver.

"No matter who it is, as long as it is eligible, you need to pay more attention, and the rickshaw driver can't be ruled out, it's just that he just killed someone, so he probably won't show up in front of people so soon, let them continue to squat!" Zhou Qifeng said again: "By the way, let people pay more attention to suspicious people who go to the vicinity of the hospital, especially those who are wearing lotus leaf hats near the hospital and meet the characteristics of the murderer." ”

"Okay, I got it." Zeng Yunlong noticed what was in his hand from the beginning and asked, "What is this?" ”

"I found it at Liu Yan's house." Zhou Qifeng glanced at him and said without any emotion: "Next time I take someone to investigate the case, search carefully." ”

“……”

Zeng Yunlong smiled awkwardly.

"Also, go and let Ming Yixuan go, he can already rule out the suspicion of murder."

"Good!"

Ming Yixuan was released from prison, except for the police department, he actually had a feeling that he had finally regained his sight!

He didn't hear the news that the real murderer was caught, it seems that the third child and Ah Ming persuaded Zhou Qifeng, otherwise he would be such a fair and strict police officer, how could he let him go so easily.

As soon as he left the police station, a man in tattered clothes stood in front of him with his head down.

Ming Yixuan moved a step to the left in disgust, who knew that the little beggar also moved a step to the left, Ming Yixuan frowned, stared at the little beggar who was not tall and had his head down, and took out a piece of ocean from his pocket and gave it to him, "Hurry up and go, hurry up, don't look anywhere to beg for money!" ”

The little beggar accepted his money, suddenly looked up at him and raised his eyebrows, but his face was dirty, Ming Yixuan frowned, "You are the girl who tricked me into helping you escape last time, Zeng Qian?" ”

"Shh Zeng Qian motioned for him to be silent and pulled him aside, "I'm here to wait for you to come out!" ”

"How do you know I'm here?" Ming Yixuan slapped her hand away in disgust and looked her up and down, why did she go out for a while and then join the beggars?

"Uh...... Because I saw Ming Sanshao coming to the police department last night, and I heard that you didn't go home all night, I thought you might be locked up here! ”

"......" Ming Yixuan frowned, "Why are you waiting for me?" ”

Zeng Qian opened her eyes wide and said, "I'll wait for you to take me in!" ”

Ming Yihan twisted his eyebrows, and he snorted, "Hall Master Zeng's own sister needs me to take it in?" And your uncle is in there! Otherwise, I'll help you get your uncle out!" ”

"Oh, no!" Zeng Qian grabbed his arm, "I really need your take-in, I just don't want to go back!" ”

Ming Yixuan smiled politely, "I'm sorry, that's none of my business, I can't afford to provoke you, the Bodhisattva, you better go elsewhere!" ”

"Don't! Anyway, we have also worked together once, and you know who I am, let me tell you, if I go back now, I will definitely break my brother's leg! ”

"That's none of my business!"

"You!" Zeng Qian puffed out her cheeks angrily, and she glared at him, "It all shows that the second young man of the family knows how to pity the fragrance and cherish the jade, and when I saw it today, the rumors turned out to be fake!" I still pity the fragrance and cherish the jade! You're not even happy to help others! ”

“……”

Ming Yixuan sighed helplessly, this aunt is really ......
