"First of all, Miss Zhenzhi, who confirmed the testimony of 'the existence of dry ice', can be directly excluded from the list of suspects."

Kogoro Mouri supported his chin with the back of his hand, deep and confident, "and Mr. Takari knew that the little ghost wearing glasses was sleeping in Mr. Ishiri's room, which could be ruled out. After all, if you knew in advance that there were children sleeping inside, it would be impossible to kill people on the side.

In this way, among the remaining people, they first got up and went to Mr. Shili's room, and there was still plenty of time for the ice and dry ice to melt..."

He paused and smiled indifferently, "Miss Qinyin, I think there is no other person besides you."

Taoyuan Qinyin's face changed slightly, she looked down at her toes, and did not argue for herself as soon as possible.

"Please wait a moment, Mr. Maori." Officer Yokogou hurriedly came to his ear and whispered: "Is this okay? You don't pose in the usual posture."

Kogoro Mouri's eyebrows trembled and he looked over in confusion.

"It's just a sleeping position." Police Officer Henggou said seriously.

Chen Xing smiled in his heart. Not to mention whether the reasoning is reliable or the strange "gross profit exclusion method", it is rare to see if he makes serious reasoning once.

Kogoro Mouri rolled his eyes even more, then coughed lightly, "Anyway, Miss Kotoin, your order of crimes is as follows:

You stole the ice cubes you would use when making Chinese cool noodles and put them in your skirt pocket. Then you went to Shili's room, beat him to death with a vase next to his door, and stuffed the vase with ice cubes and put it back on top of the bookshelf.

When you walk out of the room, use the technique you just mentioned to move Mr. Shi Li's body to the next door and block the door.

But you didn't notice the little ghost wearing glasses sleeping in the room, and then go back to the kitchen and say 'He really doesn't want to eat Chinese cold noodles', and then pretends to be nothing, and he successfully completed the murder in the secret room."

Kogoro Mori stroked his beard and said reservedly: "But your trick can't deceive me, a famous detective."

However, after seemingly serious reasoning, he couldn't help laughing with his signature.

Yuanzi's eyes twitched, "He always feels so weird when he is making a mistake."

"That's it." Ran Mori also stabbed.

Machi Umejima hurriedly said, "Then, where did the backup key go?"

"Eh?" Kogoro Mouri laughed wildly.

"Isn't Shili's door locked?" Gao Risheng also questioned.

"Well, well, I guess I will find the key somewhere in the future, right?" Kogoro Mouri began to vaguely again.

Conan shook his head in his heart. Sure enough, he had to do his own job at this time.

He said childishly: "This thing is Bing!"

"Ah?" Kogoro Mouri couldn't help wondering if this kid was really smashed and spoke strangely.

Conan said innocence: "Will water turn into ice after it freezes?"

Kogoro Mouri turned his head. This was obviously a very simple physical phenomenon, but why did he inexplicably become suspicious and become less confident when this kid asked?

"When it comes to freezing, the sports drink that Miss Qinyin has drunk!" Police Officer Henggou's eyes lit up, "It's true that the spare key is hidden in that place."

Yuanzi shook her head, "Impossible, Impossible. She also gave me that drink. It was almost frozen inside, so it was difficult to pour out the drink again."

"Will that put the key inside before the drink freezes?" Officer Henggou guessed.

"In this way, the key will sink to the bottom of the beverage bottle and you can see it at a glance," said Ran Mori.

When Conan heard this, he smiled and said, "So I said, if there is a kind of magic water that can freeze when the key is put in, then it will be fine."

When Kogoro Maori heard this, he snorted coldly: "Idiot, how can there be water in this world that only appears in comics?"

"Of course there will be." Amuro Toru smiled in a low voice, "It's just too cold water."

"What?" This touched the blind spot of Kogoro Mouri's knowledge.

And Chen Xing swallowed the words he was about to blurt out. In fact, he was still wondering why the word "too cold water" was just around the corner.

It seemed like he had heard of this word for the first time. After all, it was not found in a cuisine magazine, but he seemed to know what it meant.

Probably seen on the Internet.

Toru Amuro explained: "That is a water that will not freeze into ice even if the water has reached the freezing condensation point, and it will still remain in liquid form. But as long as the excessively cold water vibration is used, it will quickly start to freeze.

The method of making is that in order to cool evenly, the beverage bottle will be wrapped in a towel and placed in a freezer of about minus five degrees Celsius. It will be enough for about four or five hours. Then vibrate the beverage bottle, and the excessively cold water will slowly freeze down along the surface of the beverage bottle from above."

Amuro said in a relaxed tone: "Miss Kotoin should have thrown the key into a sports drink that has become too cold water, vibrate the beverage bottle, and when the beverage bottle starts to freeze, immediately turn the beverage bottle over. In this way, the key will stay in the center of the beverage bottle, and then give it to Miss Sonako when it is completely frozen."

When he heard this, Yuanzi couldn't help but pinch her throat, her expression a little confused. If what he said was true, she probably couldn't eat dinner.

Toru Amuro said: "The sports drink itself has a darker color and it freezes into a gel shape, so the key placed in the beverage bottle will not be seen."

Officer Henggou's eyes lit up, "So if you just thaw that can of sports drink..."

"Yes, I think I'll find it." Amuro said in a faint voice: "Discover the traces left by Miss Kotoin's killing Mr. Ishiri."

"Let's talk about this kind of thing when you really discover it!" Umejima Machi said loudly.

"If you didn't find out, you guys..." Gao Lisheng was also angry.

But before he finished speaking, he was interrupted by the sound of the Taoyuan piano behind him.

She whispered: "I will definitely be discovered. I will see a spare key that has been stained with my fingerprint. I was very nervous at that time. The key had fallen into Shili's blood pool."

"..." Yuanzi swallowed in her throat, and she wanted to cry a little.

Umejima said inexplicably: "But why did you give Ishiri..."

"Of course it's to avenge Guasheng!" Taoyuan Qinyin said: "Because I like Guasheng very much."

"Is it because Guasheng took Shi Li's words seriously and therefore died?" Gao Lisheng asked.

"If there is such a high snow accumulation, even if you jump from the second floor, you won't die. Ishiri's words are indeed not cautious enough." said Mama Umejima.

Taoyuan Qinyin shook her head, "The night when Guasheng's body was moved out of the scene, I couldn't sleep. When I walked to the balcony, I found Shili digging snow underneath, and I didn't know what I was looking for.

At first I thought he just couldn't believe that Guasheng died like this, so he dug snow in a place where Guasheng was no longer there and tried to find him.

Later, I found out that he was looking for the scarf around his neck. The smile he showed when he found the scarf, which had already revealed all the facts."
