"Shh Before Gao Cheng''s voice fell, all the students around him consciously stopped speaking. Many even covered their peers'' mouths and looked at Gao Cheng with patience and excitement, which made him feel the personal charm of Shinichi Kudo in school.


    "Xinyi..." Xiaolan looked at Gao Cheng, afraid of dreaming. "Are you really Xinyi?"


    "Idiot," Gao Cheng said with a stiff head and no good airway, "what are you talking about in your dreams? I just wanted to surprise you


    With that, Gao Cheng turned to several suspects again, especially the short haired girl hung, and put on her dance clothes: "sorry, I don''t know why you want to kill people, but since it''s murder, I won''t let it go. I hope you can turn yourself in..."


    The short haired girl is familiar with her alma mater''s younger brother, Kudo Shinichi. Her pressure soared. She forced herself to smile in a cold sweat and said, "please, why am I the murderer? I can''t poison it... "


    "Yes," Mu Mu Mu said confusedly, "brother Kudo, Mr. Putian and the other three didn''t find any poison in their cups, and Mr. Putian almost drank up his drink. What''s more..."


    Gao Cheng gently smile, did not continue to persuade short hair woman, direct reasoning: "indeed, at first glance, Mr. Putian seems to be taking poison to commit suicide, but if the killer used ice?"


    Mu Mu and others were stunned: "ice?"


    "The potassium cyanide is sealed in the center of the ice, which will not dissolve in a short time," Gao Cheng analyzed with ease under the gaze of his eyes. "So even if Mr. Putian drinks all the drinks, there is no poison left in the cup. The murderer just used this simple but difficult method to be suspected."


    "But toxic ice?" The dusk of the eyes became more confused.


    "Did Mr. Putian''s cup cover open when he was poisoned? And it fell to one side with the straw, right? " Gao Cheng asked.


    "What''s so strange about that," snorted uncle Maori. "He must have clenched the cup when he was in pain..."


    Gao Cheng said: "please, isn''t the cup still good? There is only one reason to open the lid after drinking the drink, that is, Mr. Putian wants to eat the ice in it, that is to say, pour the poisonous ice out of the glass and eat it.... "


    Next to curly hair surprised way: "Putian doctor seems to really like to eat the rest of the ice, at that time there is still the sound of biting ice."


    "Is it true?" Mu Mu''s face was serious. "I see. As long as we know that the dead have this habit, we can use this method to poison, and it won''t leave any trace... But why do we say that the murderer is miss Hongshang?"


    "It''s very simple," Gao Cheng glanced at the fat man, the curly haired girl and the student sister, and analyzed them one by one. "Only Mr. Sangu and miss Noda who had passed the cup could not add ice cubes. Miss Caizi, who was selling drinks, could, but she specially changed the iced coffee into coke for Putian to change. Besides, other people ordered iced coffee just like Mr. Putian, To determine the probability of poisoning Mr. Putian, there are only five levels... "


    Gao chengdun looked straight at the girl with short hair and said in a deep voice, "Miss dancer, although there are many people in line, you don''t have to buy it until the performance is about to start, do you? Why wait until the show to get your seat back? "


    Short hair girl looks ugly: "this..."


    "Mr. Putian didn''t add honey and cream because he found that coffee had been replaced by coke, but why didn''t you put it?" Gao Cheng said step by step, "when you go back to your seat from the bathroom, the lights in the audience are turned off because of the beginning of the performance. If you haven''t touched the drink in advance, how can you know it''s not coffee?


    "I think you originally planned to add honey and cream to the iced coffee at the booth, and then add the poisonous ice. But after adding the ice, you found that the coffee was replaced by coke... The reason why you didn''t return to your seat until the performance started was that you were worried that Mr. Putian would take it and change it before turning off the lights."


    The short hair girl''s eyes trembled, and she felt that she was completely seen through by Gao Cheng.


    It''s like seeing everything with your own eyes


    "No, it''s worthy of Shinichi Kudo. A famous detective is a famous detective," the short haired girl said with a deep breath. "It seems that I may have poisoned, but have you forgotten something? Putian and I ordered iced coffee, and I gave all the drinks to Sangu. I didn''t know which cup he would take to Putian. What if I drank it myself? "


    Gao Cheng shook his head: "it doesn''t matter which one, because you have added poison ice to both glasses."


    "Both?" Mu Mu was shocked and said, "how can it be? Kudo, she has finished her own glass, and she hasn''t even left any ice


    "Why don''t you just hide?"


    Gao Cheng took out the wallet he found in front of the restroom: "this is the one I found in the restroom just now. If I put some pieces of dry ice in it, I can bring the poisonous ice into the venue intact. After poisoning, I will give the drink to Mr. Sangu, and I will go to the restroom to dispose of the dry ice, until I can dispose of the poisonous ice..."


    With a smile, Gao Cheng put a copper coin into the short haired girl''s Hoodie: "there''s only one place."


    "Oh?" The service department was also very surprised, "copper does react with potassium cyanide, but how do you know it''s in the hat?"


    He was surprised to think that the "Kudo Shinichi" in front of him was actually Gao Cheng. Not only his image and temperament were the same, but also his reasoning was the same. Compared with him, his previous disguise was too bad“ Is it because of the rain? " Without waiting for Gao Cheng''s response, Hong Shang said with a smile, "just now we took the police officer outside. It was raining, but I didn''t mean to wear a hat... I lost. As your sister, I''m proud of you. I''m really a famous detective in Didan high school." Mu Mu and Gao Mu went to Hong Shang''s body and nodded, "please talk about the others in the Bureau." Gao Cheng silently watched Gao Mu take Hong to the dance dress and several other related people leave. His ears were filled with students'' exclamations. Although he was indifferent on his face, he could only smile bitterly in his heart. It''s better to get away quickly... "Kudo," Mumu successfully solved a case, especially when he saw Kudo Shinichi again, he was very happy, "so long no see, you''re still reliable here! Sharper than Maori! Would you like to listen in on the confession? "“ No, no, I still have something to do, "Gao Cheng said with a dry smile." I''ll have to ask officer Mumu to keep secret the part that has something to do with me this time. " In the bathroom, Gao Cheng finds an excuse to escape and find Conan who has taken the antidote to recover. Dr. Ali, who received the news in advance, was ready to change his clothes. As long as Conan, who changed back to Shinichi Kudo, went out, it was almost impossible for anyone to detect the abnormality. After all, in ordinary times, although Gao Cheng and Kudo Shinichi look alike, there is still a big difference in image and temperament. This time, Kudo Shinichi appears in front of everyone, and even Xiaolan is frightened“ How''s it going? " Gao Cheng changed into a casual suit and bared his teeth to Kudo, who had taken medicine and was weak. "I''ve been a big help this time, haven''t I?"“ What do you mean Kudo wiped the sweat on his face, and his brow jumped straight. "Didn''t he say that it would be OK for Xiaolan to see it afterwards? It''s a big trouble to use someone else''s identity to solve a case without authorization
