After returning to the homestay, Conan curiously circled around the insulated box until Chen Xing opened it and then lost interest.

"You're really bored enough." He laughed.

Chen Xing covered the cover of the insulated box without making any noise.

Haibara Ai held his arms, "Didn't you find out yet?"

"What did you find?" Conan was talking casually, but suddenly became stunned.

Haibara Ai smiled at him.

"So that's it, that's the case!" Conan slapped his palm and suddenly realized.

Then, he looked at Chen Xing with expectation, suggesting that the meaning should not be too obvious.

Chen Xing seemed to have not seen it, and said to himself: "Actually, if you want me to say, the most boring one should be Dr. Agasa, right?"

Of course Conan understood, and when he heard this, he curled his lips and had to choose another tool.

The wind outside stopped, the thick clouds blew open, and the bright moon filled the ground.

Conan summoned everyone to the living room in the name of Dr. Agasa.

"What's the matter if you say something?" Ryoko Iibuno asked in confusion.

"Cough cough." Dr. Agasa turned his back to the sofa, covered his mouth and coughed. The primary school student was nestled in the sofa behind him, and he picked up a bow.

"It's because I already know the truth about this murder."

At first glance, the old but full of vigor and extremely confident voice shocked the three sisters in the Bing Room.

"Murder? Wasn't that an accident?"

"No, Mr. Yayan's death was not an accident. The prisoner set up a trap on that path and deliberately made him fall to death, which is a planned murder plan." Dr. Agasa spoke calmly.

"Wait for a moment." Aya Ichimu couldn't help but get up, "But no trap was found at the scene."

Ryoko Icewood nodded, "And after Mr. Masahiko left, we were together all the time, and no one left to the scene to deal with the trap."

"Dr. Agasa" smiled faintly, "Because it was not dealt with at all, the trap should still be left on the scene now, but no one can see it."

Facing the three sisters in the Ice Room who were surprised and suspicious, even though Dr. Agasa didn't know what she was saying, she still trusted Conan very much.

"Yes, the prisoner used snow and ice as a trap." In the incredible expression of the crowd, the detective made a reasoning. "The prisoner first concentrated the snow on the side close to the mountain wall. In this way, Mr. Yayan would avoid this and choose to go near the cliff. First, limit the route he could take, and then place the ice plates made in the refrigerator in advance there."

Mitsuhiko said 'ah' and suddenly said: "So that's it. If the ice and snow are mixed together, you can't see it, and it will melt sooner or later."

Ryoko Ice Room couldn't help but say, "Wait a minute, what do you say so..."

"Yes, the physical evidence is gone completely." Dr. Agasa said: "But the prisoner made a mistake."

Conan turned over and sat up from the sofa, walked over and put the things in his hand on the table.

"This is something I found at the scene where Mr. Yayan fell, and there is this one." As he said that, he put the packaging bag he was holding in his handkerchief on the table, which he found in the grocery room not long ago.

Mitsuhiko immediately said: "I remember it was a bag of rice cake ice cream that was just launched yesterday."

"That's right." Conan praised, pointing to the debris that had been placed on the table before, "and this is the debris of this."

Chen Xing thought for a while, "Is it what Yuan Tai stole from the refrigerator before?"

Yuanta was so scared that he covered his mouth with his hands, "How could you know?"

Conan smiled and said, "I still remember that during dinner, there was no dish using garlic, but it still emitted that flavor because the source of the taste was Yuanta."

"Did you breathe after stealing your food?" Mitsuhiko whispered.

Yuan Tai said awkwardly: "There is no way, because I was too hungry at that time."

Conan secretly turned back to the sofa and continued, "Just when Yuanta was stealing rice cakes and ice cream, the water used by the prisoner to make ice chunks was in the refrigerator. The debris that fell accidentally fell into him when he ate it, and it was iced directly inside.

Then, without discovering it, the prisoner directly used the ice plate to commit the crime. Apart from that, I really couldn't imagine other reasons why the rice cake crumbs would appear on the scene in the end. That's right, it's impossible for the prisoner to have anyone other than you three who live here."

After hearing this, Mitsuhiko immediately said, "I understand, the prisoner should be Sister Xiao Ling, right?"

"You are right. We witnessed Miss Xiaoling walking back from the road. She walked back empty-handedly without warning. But if we wanted to set up such a trap, we needed an insulated box for carrying ice plates and a shovel for shoveling snow. It was impossible to have empty hands."

Conan said: "I won't say anything else. If it's a prisoner, it's absolutely impossible to call us. So Miss Xiao Ai is not a prisoner, but an eyewitness."

"What?" Several people in the venue looked in surprise.

Conan continued: "I think Miss Xiao Ling should just run into the real prisoner who came back from Xiaolu. Because she was curious, she went to Xiaolu to take a look, but at that time, she should not have found the trap set by the prisoner. If she found it, she would stop the prisoner."

"No, I found nothing!" Aya Ichimu firmly denied.

"Xiao Ling, it's okay." Ryoko Ichimu suddenly spoke, "Yes, I did everything, because I am like my mother in the tree, so I have to drive away the pests that are wrapped around the tree."

The tree in the Ice Room opened its mouth, "Sister Liangzi."

"In the tree, please understand, it's all for you." Ryoko Iibuno looked into her eyes.

Conan was silent for a moment and said, "To commit this case, you need to take out the ice plate from the refrigerator to achieve a way. Moreover, in the kitchen with a refrigerator, there should be only Miss Ryoko who had to prepare dinner. So no one was suspected except Miss Ryoko."

Ryoko Ice Room secretly breathed a sigh of relief when she heard this.

Chen Xing silently observed the reactions of several people, and he had already guessed in his heart.

Sure enough, Dr. Agasa raised his chin, "Miss Ryoko, although I want to say that, unfortunately, you are not a real prisoner."

The old and the young cooperated very well, but Ryoko Ice Room frowned.

"Because you love your sister Shuri as much as your daughter, it is impossible to kill her boyfriend by making Miss Shuri sad for the rest of her life." Dr. Agasa said in a deep voice: "You are just to protect her. The real prisoner is Miss Shuri!"

"Eh?" Azumi and the other two looked in disbelief.

"Didn't you just say I made it?" Ryoko Ichimu suddenly stood up, "That's right, even the bag of rice cake ice cream was hidden."

Dr. Agasa said calmly: "You are doing this to protect the tree, right?"

"No!" Ryoko Icewood said anxiously: "Xiao Ling, did you see me in the small road in the evening? Right, tell me quickly."

She grabbed Bingmu Aya's hand so hard, and her eyes begged.

"No, stop talking!" said the tree in the ice room with his head down and sobbing.

Ryoko's face turned pale.
