Due to the suddenness of the incident, Ouyang Xiu and Zhongli Wan'er had no time to react, they could only watch Zheng Hanfei fall, and after a while, the two realized how Zheng Hanfei was doing, and left their seats one after another, but unfortunately Zheng Hanfei had already fainted at that time, and he couldn't hear any sound at all, let alone whether Ouyang Xiu understood what he meant.

"Hey! Feed! Zheng Hanfei, wake up! Wake up! At first, Zhongli Wan'er thought that Zheng Hanfei was just pretending to faint, the purpose was to scare her, so she smiled, walked in front of Zheng Hanfei, and shouted loudly while patting his face with her hand, seeing that he was not awake, she increased her strength, and Ouyang Xiu, who was watching, was stunned for a moment, forgetting to stop Zhongli Wan'er from stopping.

"It turns out that he really passed out." Zhongli Wan'er shook off her numb hands, pursed her lips, and said, "I thought he was trying to scare me, but why was he so careless, his physique was too weak, but I was relieved to fight so much, and I forgave him for the previous incident, hum!" Somewhat cheaper for him too. ”

It's cheap for him, my aunt, Zheng Hanfei is that kind of person, and he scares you, you think of him too badly, it seems that Zheng Hanfei is right, you are really a child! Looking at Zheng Hanfei, whose face was already swollen, Ouyang Xiu sighed helplessly, he didn't know what to say, anyway, it had already happened, and Ouyang Xiu couldn't stop it, but he could imagine Zheng Hanfei going crazy after waking up.

"Forget it, this is not a good thing, at least you don't have to trouble me to deal with the aftermath." Ouyang Xiu knew the reason why Zheng Hanfei fainted, and couldn't help but breathe a sigh of relief, looking at the candy paper that Zheng Hanfei was holding tightly in his hand, Ouyang Xiu seemed to understand something, pinched his chin, and said something that Zhongli Wan'er couldn't understand, "So that's the case, no wonder Zheng Hanfei will understand, but the evidence ...... Wait, I remember that glass of water...... If this is the case, then Wang Mengmeng has made a very big mistake! ”

"What's wrong?" Zhongli Wan'er was a little confused, "Hugh, what are you talking about, why can't I understand a word, what water glass?" What evidence? What does candy wrapper tell you? ”

"Wan'er, you do me a favor." Ouyang Xiu didn't answer Zhongli Wan'er's question, but said irrelevant words, "You go find a flight attendant, and then ask her Wang Mengmeng...... What do you think? Questions? If it doesn't work, I'll go by myself, but you have to be optimistic about Wang Mengmeng and don't let her leave first class. ”

"I'll go!" Zhongli Wan'er knew that this task must be extraordinary, and her curiosity was temporarily suppressed by her, so she nodded hurriedly, "As a member of the detective agency, this kind of thing can't be left to you, leave it to me, I guarantee that I will be caught!" And listening to you say this, I vaguely understand what poison is, so you can reason quickly. ”

"I'm sorry for you!" Ouyang Xiu said a word, watched Zhong Li Wan'er leave, and then shouted to the crowd: "Listen to me, I already know who the murderer of Ji Yanyan is!" ”

"Who is it?!" Hearing Ouyang Xiu say this, Ren Xueli, Wei Hai, and Xiang Xin hurriedly stood up, their faces were full of anxiety, they were eager to know who was ruthless in poisoning Ji Yanyan, and the mysterious man also glanced up at Ouyang Xiu, a gleam flashed in his eyes, as if he wanted to know how Ouyang Xiu knew about the murderer.

"Actually, I already knew who the murderer was, and she showed a flaw when the murderer died, but I didn't have evidence at that time, let alone what the poison was, so Zheng Hanfei and I didn't say who she was, but Zheng Hanfei and I kept looking at her, am I right? Wang Mengmeng, you are the murderer! ”

As soon as these words came out, there was a thunderbolt from the sky, Ren Xueli, Wei Hai, and Xiang Xin looked at their friends in disbelief, they really didn't believe that such a beautiful and gentle person was so ruthless, but they still believed Ouyang Xiu, after all, he was from the Sherlock Detective Agency, if he was not completely sure, he would not say such a thing, and doing so would only discredit the Sherlock Detective Agency.

"Can you please stop talking nonsense!" Wang Mengmeng slowly raised her head, looked at Ouyang Xiu without timidity, and there was a hint of mockery in her tone, "I'm a murderer, it's really a joke, and you still say that I showed a flaw, so tell me, what is that flaw?" ”

"Okay!" Now all the clues show that Wang Mengmeng is the murderer, no matter how much Wang Mengmeng pretends to be innocent, Ouyang Xiu will not believe that his reasoning is wrong, so he said, "Let me ask you a question, why did you say that Ji Yanyan was dead when he was lying on Zheng Hanfei's body?" You didn't get close to him, how do you know, he may be in a coma, can it be said that you know that he is dead just by looking at it, hehe, congratulations, your medical level is higher than that of a medical professor in Huaxia Kingdom. ”

"I ...... Have I ever said anything like that? A trace of panic flashed in Wang Mengmeng's eyes, and he didn't dare to look at Ouyang Xiu, but he didn't admit defeat, "Even if I say it, you can't conclude that I'm a murderer just because I say this, right?" And didn't you say that Ji Yanyan was poisoned? What is that poison? Didn't you already know when you searched my body, and I didn't have any poison on me at all? ”

"You've already used up the poison, and you should have found it out if you didn't find out." Ouyang Xiu continued, "And that's not a poison, it's just a medicine that can kill ordinary people if they use too much, if I think correctly, you should use oral hypoglycemic drugs, dissolve a large amount of hypoglycemic drugs in water, you can't see anything unusual at all, hum!" What a good idea! ”

Because of being told through, Wang Mengmeng couldn't say anything to refute at all, so she could only bow her head silently and continue to listen to Ouyang Xiu's reasoning, and this move made Ren Xueli and the three of them disappointed in their eyes, if Wang Mengmeng could still innocently confront Ouyang Xiu, then they could still believe that Wang Mengmeng was not a murderer, but now that she is like this, anyone who sees it knows that she has acquiesced to her identity.

"Hypoglycemic drugs are cures for diabetics, but in your hands, you turn them into poisons that kill healthy people." Ouyang Xiu continued, "I think, when you give the deceased the first glass of water, put the hypoglycemic medicine in the water, and after the deceased drinks it, there will be no performance in a short time, but then there will be some symptoms similar to airsickness, and the deceased is already airsick, so whoever sees him will treat him with the symptoms of motion sickness, but he didn't expect that his symptoms were caused by low blood sugar, and he missed the best treatment time, so he died, I am not wrong, Miss Wang Mengmeng." ”

"Do you have proof?" Wang Mengmeng yelled at Ouyang Xiu, "It's just your reasoning, there is no evidence at all to prove that I did it!" ”

"Of course there is proof!" Zheng Hanfei woke up slowly, and the sharp pain in his head still made him cover his head, and when he heard Wang Mengmeng's words, he said, "Although Ji Yanyan inadvertently dropped the cup on the ground and spilled some water, there are still some in the cup, and in terms of psychology, you will definitely not pour out the water with hypoglycemic drugs, but drink it and destroy the evidence directly, I am right, the candy in your pocket and the exquisite empty box can prove all this, and you eat a lot of sugar after drinking the water to ensure that you have no symptoms." ”

"Awake?" Ouyang Xiu raised his eyebrows, seeing that Zheng Hanfei had not changed, so he asked with concern, "Nothing, right?" ”

"Nope! Thank you for being unconscious, and even more so for waking up at this time. Zheng Hanfei knew that Ouyang Xiu was referring to the matter of the second personality, so he replied with a smile, "I didn't expect you to solve the puzzle yet, it's really cheap for me!" ”

"So what, you still can't prove it, it's just your blind conjecture." Wang Mengmeng didn't care about the conversation between the two, pointed at Zheng Hanfei and shouted, "If you are slandering me, you will discredit the Sherlock Detective Agency." ”

"You're wrong, when I said this, there is already evidence that proves that you are the murderer!" Zheng Hanfei said slowly, "Since you drank the water of the poison, you will definitely not use the original cup to fill another cup of water for the deceased, and you will definitely change the cup, if I guess correctly, it should be the cup you used or a new cup, but this is also evidence to prove that you are the murderer, because when you gave Ji Yanyan the second cup of water, Ji Yanyan didn't even touch it, but I touched it, if you are not the murderer, there should be his fingerprints on the cup, otherwise, you are the murderer." ”

"Hugh, I found it!" At this time, Zhongli Wan'er was so excited that she ran over, with a cup wrapped in a handkerchief in her hand, "This is the cup used by Wang Mengmeng, I think there should be Ji Yanyan's fingerprints on it, even if there is not, the cup on Ji Yanyan's seat can prove that Wang Mengmeng is the murderer." ”
