"Huh! Help what? Lin Soul looked at her strangely, not understanding what she was talking about helping.

"Cleaning the pool, of course!" Takagi-san closed one eye, stretched out the index finger of his right hand in front of him, and said playfully.

"How do you know......" Hearing her talk about cleaning the pool, Lin Soul was so surprised that he almost exclaimed, he could be sure that he and Mr. Tanabe knew about it, and there was no one else in the office at that time, so he couldn't understand how she knew.

Only when he realized that class was already in class, he hurriedly held back his voice and turned his head to look at the humorous math teacher teaching math behind the lectern, and was relieved to see that he didn't seem to hear his own voice.

He turned around and whispered to Takagi-san, "How did you know?" ”

"Well, how do I know~" Takagi-san, pretending to be mysterious, repeated his question, and then said with a sly smile: "Otherwise, you guess the western film?" ”

"If I knew, I wouldn't have asked you!" Lin Soul shrugged his face and pouted, "How the hell do you know?" ”

Seeing that he directly admitted that he couldn't guess, Takagi-san-chan picked up the eraser he had just borrowed on the table, played with it in his hand, squinted his eyes and looked at the eraser with a soft gaze, and said slowly in a strange tone: "Eh~ I thought you were so good at Nishikata, you could easily guess my thoughts!" ”

Seeing her pick up her own eraser, Lin Soul also knew what she meant, it was nothing more than that she had just managed to make her blush, and her idea of playing tricks on herself was interrupted by herself.

"Ahem, didn't you tease me too, not to mention that I was punished for cleaning the pool...... By the way, how the hell did you know I was punished for cleaning the pool? Hiding his embarrassment with a cough, he retorted in a low voice and asked again.

"You were planning to play tricks on me first, right?" Takagi-san, tilted his head and thought about it, and said with a look of selflessness: "But if you promise me one condition, I'll tell you how I know, well, how?" ”

Lin Soul wanted to say that it didn't matter if he didn't know, because he didn't plan to let her help him clean the pool, and this kind of dirty and tiring thing should not be touched by her, after all, she was the sister she had set in, and she was reluctant.

Of course, even if he didn't want to say yes, he couldn't say no. Don't say it's because he knows what the reason is, even if there is nothing, he won't refuse if he agrees to the conditions.

"Okay, you can say what the conditions are." Lin Soul casually agreed.

I saw Takagi-san holding an eraser, holding up his palm and signaling to him, "Then give me this eraser, okay?" ”

Looking at the eraser in her hand, Lin Soul felt very puzzled, was it just to ask for an eraser?

"Well, you just want this eraser? Don't have any other requirements? He raised his eyebrows slightly, and looked at her with an inquiring look in his eyes.

Hearing his inquiry, Takagi thought about it, looked at the eraser in Lin Soul's heart in his hand, and then looked at his own eraser in her pencil case, hesitated for a moment, and a flash of brilliance flashed in his eyes.

grinning on the cherry lips, revealing two rows of neat white teeth, he smiled sweetly at Lin Soul's heart, and said, "Of course it's more than that, I also want you to make an agreement with me." ”

"Promise? What conventions? Lin Soul Xin didn't have any opinion on her supplemental conditions, but she wondered what the agreement was.

Takagi-san took out the eraser from her pen case with her slender hand, handed it to him, raised a finger and said to him: "The agreement is to exchange our erasers and use them with each other, and they must be used up, and there can be no one left, not at all!" ”

At the end, he deliberately emphasized that there should be no left.

Lin Soul Xin looked at the eraser in her hand, because school had just started, and she used her own eraser when she wiped it before, so this eraser was brand new.

And according to the plot in the original book, this eraser should have the words 'look at the door' written on one side and the word 'western piece' written on the other side.

[Is this a cryptic confession?] Lin Soul guessed what she wanted to express was the legend that "it is to write the name of the person you like on the eraser first, and then use up the eraser, so that the two will become happy."

[However...... Girl, the legend is to write the name of the person you like and then use it up, you write the name of the person you like, but this is to let the other party use up! Is that really okay? Lin Soul complained in his heart.

But if you think about it carefully, the legend says that you can use it up, maybe you can give it to the person you like to use it up, maybe the effect will be strengthened?

Shaking his head to shake off the messy thoughts in his head, his consciousness refocused on Takagi-san, nodded in her expectant gaze, and said, "I know, I'll take care of it." ”

Takagi-san's expectant gaze disappeared, and instead he smiled contentedly, carefully put the eraser in the pencil case and said, "Well, then I'll tell you why I knew that you were punished for cleaning the pool!" ”

[Well, I've almost forgotten about this stubble.] A bead of sweat left on the corner of Lin Soul's forehead, and he refused: "No need, I don't want to know so much now." ”

"No way!" On the side, Takagi said with a tough attitude.

"Okay, you promised the agreement, I'll tell you why you know, if you don't listen, what if you don't keep the agreement."

Looking at that extraordinarily serious expression, he couldn't refuse, "Okay, okay, you say, I'll just listen." ”

"Hmm!" Seeing that he agreed to listen to him, Takagi nodded, and then explained, "Actually, a teacher came to inform Tanabe-sensei in the morning and asked our class to clean the pool, but you happened to be sleeping at that time." ”

"Oh, I see." Lin Soul suddenly realized, it turned out that someone had notified her, no wonder she would know, the reason was so simple.

[Eh! It seems that something is wrong there......] Suddenly it felt as if something was missing.

It suddenly occurred to me that informing my class to clean the pool in the morning is not the same as letting myself clean the pool, so it doesn't seem to matter, right?

Full of doubts, he asked her: "I was just told to let our class clean the pool, so how do you know that I was asked to clean it?" ”

"Because it was directly notified by Mr. Tanabe, Mr. Tanabe did not directly decide to let the class clean together, which means that it is planned to wait for free time to let people clean, and our students' free time is only after school and holidays, and the classmates in the class basically live far away, so it is unlikely to be cleaned after school, then it can only be a holiday, but it is impossible to let the class come together during the holidays, although the pool is very large, but to clean, it is enough for a person for half a day."

Listening to her methodical analysis, Lin Soul's heart seemed to see a certain Grim Reaper elementary school student in her, and her jaws couldn't close in shock.

He always thought that R himself liked detectives a little inexplicably, but now he has experienced it himself, and after a deep understanding, he has a new understanding of detectives, which is indeed a slip of the mark.

Takagi didn't stop explaining this, but continued: "Since you can only clean during the holidays, you can only send a few people at most, and you can see from the indignant look when you came back from going to the office just now, Tanabe-sensei's punishment for you is to clean the pool, right?" ”

I looked at her dumbfounded for a while before I came back to my senses, and said admiringly: "It's amazing!" I almost thought Takagi-san was a real detective! ”

Takagi-san didn't feel embarrassed by his compliment, and happily accepted it, "Thank you for the compliment, in fact, detective is the second in the career I want to engage in when I grow up, and it would be good if I could become a detective in the future." ”

"Second place? So what's the first? ”

Faced with the inquiry, she glanced at Lin Soul Heart meaningfully, "The first thing is to be a housewife!" This one is also very good! ”

[I'm rubbing, this look has caught me! Lin Soul screamed in his heart, [But the housewife is good! In the future, I will take the children and cook until I get home......] Thinking about it, the saliva is about to stay.

As they spoke, their attention was on each other, oblivious to what the math teacher was teaching.

The square-faced math teacher was at home in a lively atmosphere, and quickly finished the lesson and spent the rest of the time testing the students.

In an active atmosphere, the students were very attentive and understood very well, and there was basically nothing that they could not answer the questions of the math teacher.

When a few students can't answer, the math teacher also carefully teaches again to ensure that every student learns.

And he found that the students who didn't know were concentrated near the corner of the back row, and felt inexplicable, thinking that he couldn't hear him clearly while sitting there, and the back was much louder.

His suddenly loud voice made Lin Xinxin and Takagi-san realize that they were still in class, and they returned their attention to the class.

Neither of them is afraid that they will not take the course, one is that the system has already printed all the knowledge into their heads, and the other is that they have already studied and have a good brain and strong comprehension ability.
