My name is Li Xinmu and I am an ordinary high school student.

There was an exchange student in the class, which made me a little uncomfortable.

Although it is said to be an exchange student, it is clear that there is something wrong with it, is the Chinese of the exchange student so good?

Is that so?

And that blonde hair, it's too foul! Tsk, sure enough, no matter how much you comfort yourself, the normal hair color of the yellow race is black, yes, but! Who's going to explain to me He Xi, who has pink hair on her head, hey, why can she do whatever she wants with her hair in the setting?

Hmm!

So blonde hair is really super good-looking, whether it's shiny or haggard light blonde.

Tut.

Foul!

But this alone is far from making me feel uncomfortable, although there is an inexplicable sense of estrangement, but what really makes me uncomfortable.

In last week's comic con, wasn't she the one who swapped seats with He Xi? It turns out that it is not a wig that is deliberately worn or dyed, but is it really a natural advantage? Although the blonde characters are not very good at cos, this advantage is really good.

Tut.

Also, how did this seat become vacant? There's been a lot of things that have happened lately that I haven't been paying much attention to the lectures.

And Lu Yu's eyes are obviously not right, hmph, is it really a boy? No matter how much you bury your head low, even if it is low to the belly of the table, it is useless, and I can see through everything.

Sa ~ ask. Come and ask me, just ·····

"Well, you know, who the exchange student is?"

——At that moment when the atmosphere was about to end in an awkward atmosphere, Li Xinmu's head was never pulled out of the crook of his arm again.

When: Before National Day

Location: A hotel

Character: Philres Hee

"Ahem, is it so powerful?"

Nozomi found something interesting in this database, and she was concerned about it for several days. Because it is a check-in in the background network, after the combination of the school's website and the forum is more and more deep, the school's check-in system has become no longer closed and rigid.

But Teacher Yu Wenyue's momentary fishing made Xi get some permissions, and after Xi found out that she could click on other people's names to view the records, she was happy to spy on these.

In the upper right corner of the text box, there is a small and abbreviated column chart icon, and Xi has seen the ultimate Excel with the idea of "curiosity makes people progress".

It was a non-real-time update check-in statistic, and although the data in it was updated at 12:00 p.m. every day (marked in the notes below the table), it seemed to Nozomi that it was enough. And there are a variety of different levels of catalogs, which makes it very pleasant to look at.

At first, there was nothing special at all, and there were no notable features. Xiaoxi just uses this as a way to relieve boredom, although the main reason is that she can't get on the website she wants to go on and there are no new playthings for the time being.

At this time, she didn't know what krypton gold was.

Although her friends have been helping her over and over again, popularizing the ways and means of science on the Internet, I don't know why Xi can't learn it.

Very sluggish.

Although these data are the same, 1 represents sign-in, 0 means no sign-in, Xiaoxi's task is to give herself a 1 in the corresponding position every day, and then close the website and do whatever she wants. In a way, this is the school's compensation for Xiaoxi?

Xiao Xi quickly gave up this idea, how can there be such compensation, it can't even be remedied.

This behavior is boring and mechanical, and the box that should be marked with 1 every day will be placed in the first row by the system, and the previous day's box has been changed to the fixed table. Xiao Xi wants to find a little fun in her life, and in fact she does this, looking for nearby activities, even the promotion of the supermarket will also take a few glances on the outside of the crowd.

Even she couldn't squeeze in.

But soon a new discovery is made, and Nozomi finally finds an interesting place. In this table, which covers the whole school's classes, because of the existence of the grading catalog, Xiaoxi needs to look through them one by one. While this is great for quick finding, it doesn't look so good when browsing.

Class 2 of 2017, this is a class that is very close to Xiaoxi's class, and the name of this class is below the first class. Although Xiaoxi didn't have any thoughts about this, it was obvious that rabbits didn't eat the grass next to the nest.

Xiaoxi didn't have enough interest in this class, and didn't ask about the sign-in of this class for a long time.

But what should come is still coming, when all opportunities are exhausted, the charm of this class has soared, just like a collection card, the initial freshness and the later desire and dissatisfaction are so irresistible, in this strange feeling, the 2017 class 2 was still turned over.

Just like the shepherd boy who crossed the mountains and crossed the ocean, at the end of the story, the treasure is not in the distance in the dream, but at the feet of the dream. After clicking on the text link that reads "Class 2 of 2017", the appearance of the underlined indicates that the jump is about to occur.

Xiaoxi also discovered the first puzzle she saw.

Five students were absent at the same time, and two days later, only two students checked in again. The remaining 3 students slowly resumed checking in a week later. It certainly wasn't right, but she couldn't get any more information.

And today, it was the day when the last student returned to check in. After the sign-in sheet, which was finally connected into a vertical line, was closed, Philres Hee lay on the soft futon and enjoyed the pleasure of softness and brain operation.

Clearly, she loves puzzles.

Sherlock Holmes was her idol, and although many times she thought that these astonishing reasoning were unrealistic, this did not hinder the greatness of literature. Although the Sherlock detective she first came into contact with was not one of the four signatures of Conan Doyle, the tall, lanky, curly-haired detective in a suit and leather shoes had largely dwelt in her psyche.

She loves puzzles.

Clues are the key to decryption, and now her only clue is time, and only time can help her open her mind when she doesn't quite know who these people are.

Obviously, this could not have been a normal incident.

When she looked up posts about these people on the school forum, a name caught her eye.

A week before the mysterious incident occurred to these six people, their math teacher had been called to investigate once, and the matter was put in the announcement by the student council, but it was not hung on the cover, and the name of the filing announcement indicated that it was not a relatively important announcement.

Among the retweets of this post, there is the title of an anonymous account.

There are only three words: find Lu Yu.
