Conan: I Am Not a Snake Spirit

Toru Amuro was originally standing at the door of the ward with Ike Feichi and Koshizui Nanatsuki. After listening to Mouri Kogoro and the police talking about this issue, he took two steps into the ward and actively joined in the reasoning, "It's because she had the gun in her right hand." Holding something? Like looking at photos on your phone."

Megure Thirteen looked at Toru Amuro, a little confused, "Looking at photos on your phone?"

"That's right," Toru Amuro analyzed calmly with a smile on his face, "When a person concentrates on doing one thing, it is easy to ignore other things, even the position of the cup or the handle. If the direction is slightly changed, he may pick up the cup and drink tea without realizing it. The criminal may use this kind of psychology to poison. As long as the victim is not paying attention, he will put the poisoned teacup with him. By switching the victim's tea cup, the victim can get the poisonous tea and drink the poison without any precautions..."

As he spoke, Toru Amuro looked at the coffee table with teacups next to Megure Thirteen, "The four of them drank tea without using saucers. They placed the teacups directly on the coffee table, so it was quite easy to change the position of the cups... Right? Teacher Mori!”

"Ah..." Mouri Kogoro didn't expect that Toru Amuro would suddenly name him. He was a little confused, but he still tried to pretend that he wasn't surprised at all, "Yeah, that's probably it."

Beppu Huayue, who was standing at the door of the ward, couldn't help but said, "How can we secretly exchange tea cups?"

"Yes," the hospitalized patient Juri Kosaka said, "When the four of us drank tea, only Reina put lemon slices in the cup..."

"And look carefully," Happo Tokieda looked at the coffee table and reminded seriously, "the tea the four of us drank is different in color! If one of us switches the cups, we will definitely be discovered!" "

"The colors are different?" Mumu Shisan walked to the coffee table and looked down at the three tea cups on the coffee table, a little surprised. "The colors of the tea in the three cups are indeed different. From right to left, they are brown, blue and yellow…”

Takagi Wataru looked at the red tea next to the broken teacup on the ground, "The victim drank dark red tea."

Mumu Shisan pondered, "If that's the case, the victim shouldn't have taken the wrong teacup, right? Even if you don't pay attention to the condition of the teacup, it's still easy to notice the huge difference in the color of the tea... "

While Megure Thirteen was talking, Koshizu Nanatsuki walked into the ward. He stood by the coffee table and looked at three cups of tea of ​​different colors. He found that Chi Feichi was following him. He raised his eyes and looked at Chi Feichi, if there was any He thought softly and said, "Mr. Chi, my previous client was a herbalist. She also liked to drink herbal tea. When I first met her, she invited me to drink herbal tea. And he also showed me a trick about herbal tea, but I'm not sure whether this incident is like that..."

Chi Feichi looked at the three cups of tea on the coffee table and spoke in a low voice, "Can you change the color of the tea by changing the pH of the herbal tea?"

"Yeah, you've thought of it too," Koshimizu Nanatsuki also put his eyes on the coffee table, hesitating, "but I'm not sure if the tea they drink can use that kind of trick."

"You can ask them what kind of tea it is and try it again," Chi Feichi whispered to Koshizui Nanatsuki. He noticed that his phone was vibrating. He took it out and checked the new email, and then said, "The hospital's director The director sent me an email. I will contact him first and you will resolve the matter. After the matter is resolved, I will ask the dean to take Amuro and me to check Kusuda Rikudou's hospitalization information. "

"Ok," Koshizu Nanatsuki stretched out his hand to make an 'ok' gesture, smiling confidently and winking at Chi Feichi, "Don't worry, leave it to me!"

"No random discharge." Chi Feichi whispered, turned and walked out of the ward.

"This doesn't count as a discharge..." Nanatsuki Koshizui muttered in a low voice, wanting to make faces at Chi Feichi's back. He soon noticed that Conan looked at Chi Feichi and then himself in confusion, and immediately He calmed down his expression, put on a serious and solemn look, and looked at the three women at the door of the ward, "I would like to ask... what are these three cups of tea?"

Conan immediately focused his attention on the three people at the door.

Brother Chi and Sister Nanatsuki were talking together just now. They must have thought of something key!

Toru Amuro believed that Nanatsuki Koshizui would not ask irrelevant questions, so he also set his sights on the door of the ward. He happened to see Chi Feichi passing by the three women and walking out of the ward, and was confused.

Strange, what is the consultant going to do when he leaves at this time?

"Ah..." Inpatient Kosaka Juri was unable to react when faced with Koshimi Nanatsuki's question. He turned sideways to make way for Chi Feichi and then replied, "Are you talking about the three cups of tea we drank? The brown one is peppermint tea, the blue one is butterfly pea tea, and the yellow one is chamomile tea.”

Koshimi Nanatsuki looked at the puddle of red tea on the ground, "Where's the tea the victim drank? What kind of tea was it?"

"It's hibiscus tea." Kosaka Juri was mentally prepared and answered much faster.

Koshizui Nanatsuki nodded and returned his gaze to the coffee table, "So, who drank these three cups of tea on the table?"

"The person who drinks the brown peppermint tea is Happo," Kosaka Juri looked at the two people beside him, "The person who drinks the blue butterfly pea flower tea is me, and the person who drinks the yellow chamomile tea is Beppu."

Mumu Shisan was confused and asked, "Miss Yueshui, do these questions you asked have anything to do with this incident?"

"It's related. My previous client was a herbalist. She also liked herbal tea. When I met her before, she treated me to herbal tea and performed a trick on me," Yueshuiqi said. Tsuki smiled at Megure Thirteen, and quickly turned his attention to Kosaka Juri, his eyes became serious, "A trick that can instantly change the color of tea."

Kosaka Juri tightened her hands in front of her, not daring to look directly into Koshimizu Nanatsuki's eyes.

"Can you change the color of tea instantly?" Megure Shisan asked Koshimizu Nanatsuki in surprise, "Is there really such a trick?"

"Of course it's true, but I'm not sure if their tea can do it. We need to conduct some experiments," Koshimizu Nanatsuki said to Megure Thirteen, and then asked the three women at the door of the ward, "By the way, do you have any alkaline things like baking soda in your ward?"

"Alkaline stuff?" Happo Tokieda looked at Kosaka Juri who was standing there in a daze, "Juri said that she used baking soda to wash the teacup like new, so there should be baking soda here... right Right? Juri..."

"Yes, yes," Juri Kosaka looked at the cabinet in the ward uneasily, "there is a bag of baking soda there that I use to wash the cups."

"I see," Toru Amuro heard Koshizui Nanatsuki talking about 'alkaline things' and quickly reacted with a smile on his lips, "The trick Miss Koshizu said is by changing the acid-base in the tea. Let’s change the color of the tea. It is true that some teas will turn blue after adding alkaline substances, and after adding acidic substances, such as lemons, the color of the tea will turn dark red or close to red. Brown, that is to say, using baking soda and lemon slices, you should be able to change the color of the tea..."
