Conan: The Mechanic

The next day, when Chiba and Haibara Ai came to the classroom, they were immediately surrounded by other students, and they were all asking the same question.

"Did you guys just come back from Matsumoto?"

"?" Qian Yu was stunned. "What do you—why do you feel that way?"

"What they said!" One of the classmates said, pointing to Yuan Tai not far away. "They said you went to Matsumoto before."

"Uh..." Qian Yu supported her forehead and looked at the radiant Yuan Tai and the others.

By the way, why are these guys so energetic? The reason why I and Haibara Ai are still able to go to school is because I used the auxiliary unit to dispel the drowsiness, while Haibara Ai drank a large cup of coffee - originally Chiba and Haibara Ai both planned to take a leave of absence to make up for a day's sleep at home However, Haibara Ai thought that this would disrupt the rhythm of the biological clock, so Chiba could only be woken up in the morning by the alarm that sounded from the auxiliary unit because Haibara Ai touched the room, and came to school together.

Uh... It seems that when they followed Gregory around to investigate, these guys took them with them in the hotel... Could it be that they have already made up for sleep in advance?

Sighing, Qianyu nodded. "Yes, we went to Matsumoto City..."

"Does it seem like something big happened over there?" another person asked. "Today, the news is saying that there are symptoms of poisoning in Matsumoto City!"

"..." After hesitating for a moment, Qianyu shook her head. "We don't know."

There's no need to tell these children about this... Although they will be exposed to these strange things sooner or later, it's better to keep their beautiful childhood for a little longer.

"Sooner or later, they will know, won't they?" Haibara Ai glanced at him and confirmed that Conan was not there, and said while opening his schoolbag. "I'm used to lying to children with love and lies, and how to hide this dark scene? How can I say sorry when the war burns down the building block wall? Some darkness is destined to be unstoppable."

Whether those who released Sarin thought about it or not, the blissful paradise that belongs to the children has been polluted, and the lives of these children have been forever distorted by these terrorists. The hospital may heal the body, but not the heart; counseling may cover the mourning, but not the grief.

"There has never been a value that can be completely forgiven," Chiba sighed. "Exporting their own values ​​to each other, but still claiming to be noble. Spreading terror thousands of miles away, nourishing nightmares. The panic around others will come back sooner or later. It's a pity that these thugs will never know."

…………

"Huh?" Everyone except Chiba and Haibara Ai (Conan didn't come because he was too sleepy) let out a surprised voice.

"I'm sorry," Kobayashi Sumiko said to everyone with an apologetic smile. "Schools have been suspended for so long, and final exams need to be held in advance... But there is no way. Various accidents before the school caused us to take into account the potential risks, so we must use a longer holiday to deal with it thoroughly. However, Please rest assured, we have taught you all the knowledge, so you only need a little review and you will be able to pass the exam!"

"..." Qianyu and Haibara Ai exchanged glances with indifferent expressions in their eyes—for them, an exam of this level is only difficult for salted fish, even if it is taken at any time. Holiday.

But...if that's the case, why should the sports meeting be postponed until now? Originally, the sports meeting at the end of May did not have much impact on the final exam in mid-July, but the sports at the end of June will have a lot of impact on the final exam in early July... Those little guys may not be able to handle it. ?

……

"Uh..." In the living room, Qian Yu put down Yuan Tai's calculation sheet and pinched the bridge of her nose in despair. "you……"

"Did you not expect this to happen?" Haibara Ai, who was teaching Chinese characters to Ayumi (the first grade of Japanese elementary school is required to learn 80 Chinese characters), took a sip of tea and said leisurely. "Since you have agreed to their tutoring request, you must be mentally prepared for this."

"I'm mentally prepared, but..." Qianyu sighed and showed Haibara Ai's calculation sheet. "Look for yourself...I really don't want to say anything."

"Huh?" Haibara Ai glanced at the small note in Qianyu's hand—although the distance between them was about a meter or so, Haibara Ai could still see the above formula clearly. "Uh……"

"You're speechless, aren't you?" Qian Yu sighed. "And the most important thing is that I have absolutely no idea how to improve both of them...I have never encountered a situation where I would have problems with calculus..."

Qianyu has shown a very strong thinking ability since she was a child, and her mental arithmetic ability ranks among the top among all the children trained by the organization. The amount of calculation required for the regular questions of the University of Tokyo Mathematics Introductory Exam is completely within his mental arithmetic ability. Qianyu does not even need paper and pen to do this kind of question, and he can directly get the answer to the question through the most direct vertical thinking.

"Then tell him about the most basic skills," Ai Haibara said helplessly~www.readwn.com~ Even if humans can't have as high computing efficiency as computers, they can still learn from the computing model of computers. some knowledge. "

"I see..." Qianyu shook her head and continued to work resignedly. "That... first—"

When she said this, Qianyu's eyes suddenly lit up. "Wait a minute, maybe you can really use the logic loop mode..."

"?" Haibara Ai looked at Qianyu somewhat strangely.

"That," Qianyu wrote hurriedly on a piece of paper. "Mita, Mitsuhiko, look at this."

"?" Yuantai and Mitsuhiko looked at the small note written by Qianyu together.

What Qianyu wrote was not a formula or a trick, but a text version of a logic judgment program—the first grade did not come into contact with any difficult mathematics, at most two digits minus one digit, so this simple formula has been used. enough to deal with.

Judgment group 1 - which one is greater between the ones digit of the minuend and the one digit of the minuend

Result 1: The one digit of the minuend is greater than the one digit of the minuend or the two are equal - turn to result formula 1

Result 2: The one digit of the minuend is smaller than the one digit of the subtrahend - turn to result formula 2

Result formula 1——The ten digit of the minuend is reserved, and the one digit of the minuend is the one digit of the minuend minus the one digit of the minuend

Result formula 2 - subtract one from the tens digit of the minuend, and the one digit is ten minus the one digit of the minuend plus the one digit of the minuend.

Chiyu tilted her head. "This is the formula to explain how the oral arithmetic should be done in principle."

"It's so complicated..." Yuan Tai stared at the piece of paper for a long time, but in the end he just looked at Mitsuhiko's big eyes and small eyes.

"You don't even understand this!!!???"

The almost helpless roar knocked on every wall of the orange house.
