Chapter 293

"Do you remember Wang Aiping?" Lu Jingshen some curious asked, his look has some can't wait to look, Lin Wenwen in the side looking at all this, heart unnatural rolling, she always don't know what Lu Jingshen in the end to do.

"Come on, have some fruit..."

Mrs. Qian pushed the fruit tray toward the guest and sat aside. She patted Professor Qian's leg with a smile. "Don't you remember that little Ping is clever and sensible. She always came to your lab to learn from you more than 20 years ago."

"Of course I remember. You thought I was a fool!" Professor Qian shrugged his shoulders and looked proud.

"As far as I know, Professor Qian, when you were young, your main research field was chemistry, which was aimed at the development of agriculture, right?" Lu Jingshen has bright eyes and clean voice.

Professor Qian nodded, "yes, I've been working on a kind of pesticide that only aims at pests and is harmless to human body. As you know, in many rural areas, millions of people die every year because of eating or touching pesticides by mistake. This is not a small number, so when I came back from Switzerland, I still did not give up doing research in my laboratory at home... "

"At that time, I just came to work in Lin's factory and soon got to know Xiao Ping. She was about the same age as my daughter. At that time, my daughter had been studying abroad and had little time to come back. So my wife and I took Xiao Ping as our own child at that time." Professor Qian said and took a sip of tea.

"Yes, Xiao Ping is open-minded and eager to learn. He comes to our house every so often!" As Mrs. Qian said, she picked up the hot kettle and added some hot water to Lin Wenwen's cup. She looked at Lu Jingshen's cup and then put down the kettle.

"What does she learn from you? As far as I know, her education level is only the level of junior high school... "Lu Jingshen's eyebrows slightly wrinkled, with a layer of waves.

"Xiao Ping just said that she was very interested in the research in the field of agriculture. She also said that her brother died of eating pesticides by mistake, so she supported my research very much. She also wanted to find out what was going on, so she tried hard to learn from me." Professor Qian said with a firm face.

Mrs. Qian should also talk to Wang Aiping. They both seem to be talking endlessly, "yes, Xiao Ping often mentioned her dead brother at that time. Their feelings seem to be very good. We can see that Xiao Ping is a good child who attaches great importance to love and righteousness!"

"Ah..." Lin Wen sneered unconsciously, but he made a sound unintentionally.

"Oh, nothing!" Lin Wenwen responded awkwardly. She waved her hand, bowed her head and continued to drink tea. She didn't speak any more.

Lu Jingshen chuckled. Of course, he knew that Lin Wenwen's inner activities at this time were the number of thousands of troops passing by.

"By the way, do you know Xiao Ping? Why do you keep asking about her? " Mrs. Qian said, looking puzzled.

"It seems that the relationship is too shallow to know each other. We are too familiar with Wang Aiping..." when Lu Jingshen said this, his eyes were cold, and he looked gnashing his teeth, but it was just Lin Wenwen's emotion.

During the chat, the old couple seemed to be very simple. They didn't even know the identities of Lu Jingshen and Lin Wenwen, so they were excited to invite them into the house. They also said so many words, which is enough to tell.

After listening to Lu Jingshen's words, Professor Qian and Mrs. Qian said happily without even thinking about it, "Oh, the world is so small, you know Xiao Ping. It's really fate..."

Lu Jingshen smiles, his mouth slightly up, his voice is heroic, "but as far as I know, Wang Aiping actually has no brother, she is an only child, and relatives only have a distant cousin, now living in Hokkaido, Japan."

"Ah? No, don't you remember wrong. Xiao Ping said that her brother died of eating pesticide by mistake. I remember clearly... "Mrs. Qian said, and Professor Qian echoed," yes, that's why she often comes to my lab to learn from me and help me... "

Lu Jingshen's expression was always serious. He looked at Professor Qian and lowered his voice. "I have a question that I want to know the answer. When you do experiments, will you use organic phosphorus?"

"Of course, I study their characters. Almost every day I use organophosphorus pesticide chemicals for separation and decomposition research. Is there any problem?" Professor Qian is unambiguous when he talks about his professional knowledge. Compared with those meaningless things, these things are deeply rooted in his mind.

Lu Jingshen glanced at Lin Wenwen, and then said, "well, that is to say, it's very easy to find some muscarinic substances from your laboratory, isn't it?"

"Muscarine?" Lin Wenwen's brain was buzzing, as if he had been vacuumed by something. The two familiar words were exactly the three words Lin Wanxin said when he was crazy. She said that Xu Wanqing was in a trance because she had been eating muscarine for a long time.

Lin Wenwen's face turned pale for a moment, and her palms were tightly clenched together, almost without blood. Without looking at it, Lu Jingshen directly covered his palm on the back of Lin Wenwen's shaking hand. His temperature gave her strength and reassurance.

Lin Wenwen looked at Lu Jingshen with a firm face. It seemed that he just knew the purpose of his coming here today. It turned out that he had heard all the words Lin Wanxin said in the factory that day and kept them in mind. For Lin Wen, Xu Wanqing's death has always been a thorn in her heart. Professor Qian frowned and answered firmly, "of course, this kind of substance is abundant in organophosphorus pesticides. My research scope is to decompose them or change their properties. Of course, I often come into contact with them in the laboratory."“ What exactly do you want to ask? I'm afraid you didn't come to see me today? " Professor Qian seemed to have some reaction. He took the Presbyopia mirror to look at the depth of landing field. After a while, he said again“ What class of students are you? I think you look familiar, but I really can't remember. Why do you keep asking about Xiao Ping? You have confused me... "Professor Qian, I'm not your student. I'm here today to learn about Wang Aiping!"“ what? You are not my student, so who are you? How do you know me? How did you get to where I live? " Professor Qian looked at Lu Jingshen and Lin Wenwen with some vigilance. His brow was deeply wrinkled“ In fact... "As soon as Lin Wenwen's words came out, Lu Jingshen interrupted her“ In fact, Wang Aiping killed a person with toadstool in those years. Today, I just want to know the truth and give justice to the dead! " What Lu Jingshen said is understatement, but it is to the point“ What? " Mrs. Qian's apple, which was peeling, fell to the ground in an instant. She could hardly believe what she heard. Professor Qian stood up, a little excited, "impossible, you said that Xiao Ping killed people in those years? I don't believe it. She was afraid of an insect at that time. How could she kill people? It's impossible. It's impossible... "It doesn't matter whether you believe it or not, but it's true. It's a fact that can't be changed!" Lu Jingshen's words are solid and forceful. He looks like a judge trying criminals, serious. Lu Jing firmly believes that the rich man Wang Aiping married actually had a wife and a daughter. Wang Aiping was a junior. She used trace amount of muscarine to put in the hostess's food for a long time, which led to her hallucination and mental confusion... "Lu Jing pauses and continues," finally, the man's wife is regarded as a mental illness, Everyone thought she was just stressed out and broke down, but she was just poisoned. Later, due to hallucination, she rushed into the road and was killed by a car. Wang Aiping naturally became the main room, and finally drove her daughter away with a trick... "Professor Qian was stunned and speechless. He looked at Lu Jingshen and said those heinous tragedies forcefully. He didn't know that the man they were almost going to be their daughter was a ruthless murderer. Mrs. Qian patted her thigh and said, "I remember. At that time, Xiao Ping often came to the laboratory to help. Once I saw her holding a round glass dish wrapped in cellophane and carefully put it into her pocket."“ I didn't care at that time. I didn't understand Lao Qian's experiment. Later, I saw it several times. It's the same situation. She often seems to take some things from the laboratory... "Professor Qian said," why didn't you tell me at that time? Those glass dishes are full of toxic substances. How can you take out the laboratory at will? "“ I thought it was only once... "Professor Qian reproached himself and seemed to feel that he had become an indirect accomplice“ Which one? " Lu Jingshen asked“ In fact, I have seen Xiao Ping take away the mushroom container secretly, but I stopped her at that time. She said that she was just curious and wanted to take it back and study it by herself. I didn't think so much at that time. I just thought that children were fond of playing. I didn't expect... "Ah, I didn't expect that I became an indirect accomplice..." Professor Qian patted her thigh and sighed. At this time, Lu Jingshen took out the recorder in his pocket, gently pressed the recording stop button, and stood up, "thank you for letting me know the truth. It turns out that all this is just my guess, but I didn't expect it to be true. Now the truth is clear!" But Lin Wenwen sat on the sofa, looking at the ground blankly, lost his mind
