It's 9:22 a.m.

Subtract the 2 minutes I wasted because of the calculations and reasoning I was about to do.

It should be counted from 9:24 a.m. onwards.

Ke Yuhan took out his notebook and calculated quickly with a ballpoint pen.

The last class of the evening ends at 18:30.

That said, in an absolute ideal scenario, there are a total of 546 minutes (9 hours and 16 minutes) available to me during this time.

If I collect information about other people during class time, I not only want to avoid being caught by the teacher, but I also run the risk of wasting other people's class time and causing negative reactions from others because of their emotional agitation, which will alarm the teacher and cause me to be punished for disrupting classroom discipline.

Ke Yuhan was brainstorming frantically, and he peeked at Xu Xuanyue.

Xu Xuanyue lowered her head and chatted with her friends on her mobile phone under the table.

Ke Yuhan shook his head, scoffed at her casual attitude, and then continued to analyze.

If I make a mistake in any of the research links in class, I may be warned by the teacher, and others will have a social denial of me from their self-perception because they don't understand me. It spreads like a plague within the class, and at that time, I myself am the "source of the disease", which will greatly reduce the level of trust of my classmates in me, thus affecting the efficiency of my collection.

To sum up, the risks are much higher than the benefits, and they are discarded.

From the second class in progress, there are 7 full lessons left today, and one lesson that is about to have 36 minutes left is directly reduced by 316 minutes (5 hours and 16 minutes) and 230 minutes (3 hours and 50 minutes).

From a realistic point of view, from 11:40 to 14:30 is the lunch break, I need to go home, and there is a high probability that the school will not leave many classmates, and I can't contact and collect, minus these 170 minutes (2 hours and 50 minutes).

To be exact, I have 60 minutes (1 hour) left to act.

"Isn't there only 6 recesses left?" Ke Yuhan frowned, and made a difficulty.

An hour? How much data can be collected in an hour?

Ke Yuhan held his chin and looked at the data on the paper in contemplation.

He suddenly found the clue!

In this afternoon's class, there is a PE lesson!

This allowed Ke Yuhan to find a breakthrough, and in his impression, there were many people, most of whom were girls, who returned to the classroom to drink water and rest during the free time of physical education class.

Unlike other people who continue to exercise during this time, intense sports will lead to an increase in the production of adrenaline in the body, which will indirectly increase the amplitude of mood swings in the human body.

And those who return to the classroom to drink water and calm down, they choose rationality, and they are more suitable for conversation.

From his point of view, this is the equivalent of an extra recess.

All he had to do was run back to the class before others arrived, and he could gather the information he wanted as if he were waiting for a rabbit.

If Xu Xuanyue doesn't notice this time period, then he will have more precious time than her, and his winning rate will be greatly improved.

The corners of Ke Yuhan's mouth curled slightly, and he looked at Xu Xuanyue again.

"Li Chuan, Li Chuan!" Xu Xuanyue lowered her head and lowered her voice and shouted to Li Chuan, who was listening to the class.

"Write down your phone number on a piece of paper and upload it to me."

This stupid guy, Ke Yuhan thought to himself.

Do things in such a hurry, do not consider the impact of external factors on their own situation.

He sighed in disdain, but also felt a hint of danger.

As soon as the bell rang for the end of class, Ke Yuhan started his plan.

He held the notepad in his left hand, and the pen in his right hand turned backwards.

"Li Shan, Li Chuan, can you tell me your contact information?" He grinned, then retracted, his hands in a gesture ready to record.

The twin brothers looked at Ke Yuhan's serious face and stiff and flashing smile, and their hearts were mixed, surprised, moved, and angry.

I was surprised because this was the only time Ke Yuhan took the initiative to talk to them since the beginning of school.

Moved because they had already seen his strong thinking logic, and they also learned from the grapevine that the person in front of them was the first in the class in the high school entrance examination.

They were angry because they had heard the previous conversation between the two people in front of them and knew the purpose of the question.

"Okay, then you can remember our mobile phone number......"

After recording the contact information of the two, without any delay, he moved on to the next target.

"Hello classmate, can you give me your contact information?"

"Okay, let's exchange numbers."

"Hello classmate, can you give me your contact information?"

"Yes, you can."

"Hello classmate, can you give me your contact information?"

"It's so direct, the mobile phone is not always in the hand, is the QQ number okay?"

"Hello classmate, can you give me your contact information?"

"Uh...... What are you doing...... I don't remember my phone number, oh, I don't remember my QQ number......"

Xu Xuanyue sat on the seat and watched Ke Yuhan running around seriously, couldn't help covering her mouth and snickering, took out her mobile phone and took a photo of him.

Time gradually passed, Ke Yuhan also ran into walls everywhere, and it was not until the afternoon physical education class came that he collected the contact information of 11 people.

At this time, standing in the line against the sun, he scratched his head: "So many people can't even remember their mobile phone numbers and QQ numbers, and their memory is really poor enough." He complained, thinking that if the people around him were as smart and rational as himself, he wouldn't have so much trouble communicating.

"Radio gymnastics! Every student must master and learn, and every morning between classes, the whole school will gather together to practice morning exercises, and the leaders will also inspect, so everyone must ...... seriously," the physical education teacher emphasized to everyone while standing under the shade of the tree.

From morning to now, Ke Yuhan has not seen her take any other actions except for seeing Xu Xuanyue collect Li Chuan's number, and he secretly thinks that there is no fraud.

"Hey, that male classmate with glasses, do it! What a daze. Ke Yuhan was named.

When the time came for free activities, Ke Yuhan immediately turned around and ran to the teaching building at the moment when the teacher said the word "disband", making sure that he was the first to arrive at the classroom, so as not to miss every student who came back to rest and rectify.

His plans went well, and even the number of people returning to the classroom exceeded his expectations.

He still asked one after another.

"Hello classmate, can you give me your contact information?"

"Yes." Su Xin, who was asked at this time, raised his head and smiled, and there seemed to be other deep meanings hidden in his calm eyes.

"Please tell me then."

"No need, I'll write it, by the way, my name is Su Xin."

"Well, I know you, you were the first girl to talk to me at school yesterday, and I also pointed out your inner ......"

"Shut up!" Su Xin shouted loudly, and his face instantly turned red. "If you keep talking, I won't write it to you!" She warned, feeling sorry for Xu Xuanyue again.

Ke Yuhan nodded, thinking in his heart: It seems that this is another girl who can't face her shortcomings.

By the time of the last class, Ke Yuhan had collected 28 phone numbers and 17 QQ numbers, and some people gave two kinds of contact information, so a total of 39 people's contact information.

He looked out the window at the sun that was about to sink, clenched the notepad in his hand, and a triumphant smile appeared on the corner of his mouth.
