"Toilet paper core?"

"Yes, it's in the garbage bin of the studio. The toxic reaction is detected from it, and Mr. Kojima's fingerprints are also detected!"

In the hallway, the police officer of Mu Mu was surrounded by a bare paper core.

"Did the prisoner poison it? Did the president touch this thing before eating hamburger? "

"Yes, and he brought it to the studio himself," Gao Cheng said, taking Xiao AI out of the toilet. "Just think about when the president came into contact with the poison. Under what circumstances do you need to untie the belt, take off your pants, and use a handkerchief?"

"Toilet, toilet?" Mu Mu Leng said, "did the murderer put this used up paper core in the toilet roll paper tube, and then the president of the island changed a new toilet paper... But that's not right. In this case, the toilet paper would be stained with poison by the president of the island?"

"What if it's a good one? In this way, the toxic part of the new toilet paper is directly torn off when it is used, and then flushed into the toilet... "

Gao Cheng looks at the three employees who are sweating a lot.

"The behavior of the outgoing president in the toilet should be like this. First of all, when he noticed that the paper had run out, he took off the poisonous paper core with his right hand and replaced it with new toilet paper on the shelf. After going to the toilet, he lifted his trousers with his poisonous right hand, tied his belt, twisted the switch on the left side with his left hand to drain water, and then dried them with a handkerchief after washing his hands

"Here, the poison on the leader's hand is wiped off, and only a small amount of it remains on the handkerchief. The next step is to take the useless paper core out of the toilet..."

"So only the right side of the pants, the belt hole and the handkerchief have a small amount of poison?" Mu Mu pondered and touched his chin, "but he's not left-handed. How can he take the paper core out of the toilet and stick it on his left hand?"

Gao mu, who was stunned, said with a smile, "Why are you so stupid, officer? He opens the door with his right hand. Of course, he has to use his left hand to get the paper core

"Huh?" My eyes turn back.

"Ouch!"

"Hum," Mu Mu Mu left Gao mu, who had been hammered a big bag, and coughed softly, "I see. Later, Mr. Chu Dao left the paper core in the garbage can of his studio and was poisoned when he ate hamburgers... The only murderer is those staff who are very used to his habits and have been in the toilet today..."

Mu Mu looks coldly at the three suspects.

"The most suitable one is Mr. Caijin who enters the toilet before leaving the island."

"Wait a minute, wait a minute," Caijin said anxiously. "Don't you think it's strange? If you use the saying just now, you can poison the president. But if the president doesn't have diarrhea today, or if no one goes to buy hamburgers, can't he kill people? It's the president himself who wants to eat hamburgers... "

"It's very simple," Gao Cheng interrupted. "I think Mr. island's coffee should be filled with laxatives."

"Cathartic?"

"Yes, didn't you say that the president of the island had diarrhea recently? I'm afraid it's because of too much medicine. In addition to the cathartic the president of the island drank, someone added another amount of medicine to his coffee. It should be gradually increased every day before the president of the island found out... "

Gao Cheng goes to Caijin and his eyes fall on the bald Imai.

"In the case of excessive laxatives, it's easy to have defecation after eating again, so Mr. Imai brought coffee and cookies together in order to let the island president go to the toilet as soon as possible... Am I right?"

Imai looks pale.

"Today well?" Caijin stepped aside and said, "Hey, it's me who goes to the toilet behind Imai. If I didn't go to trumpet, would I be killed too? Because I also ate the hamburger directly with my hands... "

"I think he'll stop you if you've got a big size or moved the paper core... And then change the plan."

"But in this case," Mu Mu frowned at Imai, "there should be a belt with poison paper core or a bottle with poison, right? Where are you hiding... "

"Everyone in the kitchen is in the triangle corner," Xiao AI suddenly came out from behind Gao Cheng and said calmly, "if it's me, I will hide it when I pour coffee in the kitchen. It's smelly and dirty, and no one will want to touch it. Moreover, even if I can't deal with it later, who will help me throw it away, and it's easy to recycle it if I want to hide it in another place..."

Imai's pupil dilates and looks closely at Xiaoai.

"Officer!" A police officer poked his head out of the kitchen and said, "it's true. A suspicious plastic bag was found in the corner of the bucket..."

"Very good!"

Mu Mu breathed a sigh of relief.

"Mr. Imai, if there is poison reaction and your fingerprints on it..."

"There should be..." Imai looked at Xiaoai and closed his eyes. "In order not to miss the chance to kill the president, I have been hiding it. In fact, I had the idea to kill him twenty years ago..."

Caijin's eyes widened: "two or twenty years?"

"It wasn't long since you came here. Didn't I want to leave here to be independent, but I came back?" Imai sneered, "the president colluded with the publishing company in advance, saying that they would not let me work as a traitor. A designer could not get a job, so of course he had to come back in frustration... This is what a friend of a publishing house told me..."

"But then how..."

"Because I can't do it, I was in the kitchen that day thinking about how to kill him when he came back, and I happened to come with my parents. Mingmei here stood behind me..."

Imai began to smile sentimentally and shed tears from the corners of his eyes.

"He asked me how I looked so terrible, whether I was looking for something, or whether I wanted to hide something... She said that I could not hide in the corner of the triangle, yes, the water bucket

"I said that my uncle was just tired from work, and it didn't matter, so she laughed sweetly... After she got out of the kitchen, Mingmei seemed to take our tools seriously and began to hide them. As long as I saw Mingmei's innocent smile, my murderous spirit suddenly disappeared..."

"Then why are you doing it again?"

"Because before that, after seeing Mingmei again many years later, I summoned up the courage to talk to the president about my independent business, but the President... He said that I am no longer what I am now. If it was 20 years ago, it would be another matter..."

Imai looks sad.

"Mingmei said that she would visit again in a week and come with her sister... But she didn't come until so long after the end... I thought she would use a smile to kill me again, but I thought it was too beautiful..."

Gao Cheng leaves with Xiao AI, but when he leaves, Xiao AI stops to look at the well taken away by the police.

That week's agreement was the end of the billion robber case.

As a grass-roots staff member, Miyano Mingmei, who has never been involved in the organization task, seems to have agreed to participate in the billion robber case in order to get herself and her sister out of the organization. In the end, it was a hoax. It seems that the organization has long had a plan to kill her.

The reason seems to be that Miyano's ex boyfriend, FBI undercover hidichi Akai, has been exposed

"Let's go."

Gao Cheng hands the helmet to Xiao AI and quietly rides on the locomotive. After Xiao AI sits down, the engine car leaves from another road.

"You haven't shown me," Xiao AI grabbed Gao Cheng's clothes from behind. "What's hidden under that floating ball? Is it really my sister who left it

"I think so. There are some tapes in it."

Gao Cheng looked around the street and stopped at a video store.

"What are you doing?" Small sad surprised way.

"Go and buy a walkman, or how can you listen to the contents of the tape?"

"No way!"

Xiao AI catches up in a hurry.

"Don't listen! If you go further like this, you will be killed... "

"I know a lot about it anyway."

"I just can't!"

Xiao AI anxiously watched Gao Cheng buy an old-fashioned player in the store. He jumped up and wanted to take it away, but Gao Cheng put the player and a tape marked "16 ~ 20" into his arms.

"Eh?"

"Fool, I went to the studio secretly just now to listen to it. These... Are all for you."

"Hum."

"Well, listen to it." Gao Cheng smiles. After paying, he walks out of the video store with sulky Xiao AI.

Xiao AI sat behind the locomotive, put on the earphone with his fingers trembling, pressed the play key, and suddenly stunned himself.

"Happy Birthday to 16-year-old Shibao. You should have a boy you like at your age, right? Mom's first love... "

"Mom?"

Gaocheng engine car smoothly drove into the street: "yes, it seems that it's all your mother's messages to you, until the age of 20... Your mother's voice is very gentle, which is not like the rumor at all, so you should rest assured?"

Xiao AI doesn't respond. She just listens to the recording quietly and leans on Gao Cheng contentedly.

As the speed of the locomotive slows down, Gao Cheng calmly returns to the detective office. Gao Cheng carefully stops the locomotive and holds Xiao AI sleeping with a bitter smile.

Xiao AI had been thinking about it before the spring break. This time, she finally realized her wish. She just didn't know what happened to the Miyano couple, whether they were really killed in the accident or by the organization

Even if he had seen "Conan", he still couldn't figure it out, because before he came to this world, "Conan" seemed to be far away from the end.

But

Gao Cheng looks at Tian Tian and smiles in his sleep.

Like Xiao AI, he has no relatives in the world. Maybe this is the reason why he accepted Xiao AI regardless of the consequences, so many things have changed a lot.

"Well?"

Gao Cheng stops at the entrance of the stairs and looks slightly at the tall figure coming out of the coffee shop.

Akai Shuuichi is still the same old, deep Eyeshadow looks a bit scary, but it will look at the eyes of little sadness, but flashed a bit of complexity.

"Don't meddle in the affairs over there." Hideki Akai said coldly.

"What happened over there?"

"You know what I'm talking about..."
