The afternoon class was quickly over, and in order to continue to promote the direction of the story in this school, Rumi and Xiuyin began to clean the classroom according to the teacher's instructions.

When the two of them were sweeping the classroom, they were naturally not idle, and at the suggestion of Rumi, they searched each student's desk pocket by the way.

Rumi had already observed that there were eighteen books in each person's desk pocket, including the two of them, and there were also eighteen books with their respective names written on them.

Due to the limited time, I don't know when someone will return to the classroom for evening self-study, so Rumi directly chose to only check the number of textbooks, and mortals with more than eighteen books will go to read them carefully.

After this search, in the end, Rumi really found a different guy, in the first row of the four groups of table pockets, Rumi found that this guy had an extra book, which looked carefully, and found that the extra was a love book of "Please let me stay in your world".

The owner of this seat, Ru Mi vaguely remembers that it was a short girl with glasses, and she didn't know the excess.

Time was pressing, and there was no time to read more, so Rumi hurriedly flipped through the book, and several of them were marked with a pen, and the corners were folded, and he took out his mobile phone and photographed them all at the folded parts.

However, just as Rumi was about to put the book back, a girl's voice sounded from the door.

"What are you doing!"

This sudden roar startled Rumi, and the book in his hand slammed into the chair at once, and then slid to the ground again.

Rumi turned her head to look at the door, but it was not the original owner of the seat, but the little girl who appeared in the small noodle restaurant!

The little girl was very satisfied with the behavior of the two men.

"Yes, it seems that you have begun to accept the setting of this game, so I wish you a speedy solution."

After saying that, the little girl turned around and left, and Xiu Yin tried to catch up and look, but the result was the same as the previous time, the corridor outside the door was empty, as if no one had ever come.

"Rumi, what now?"

"At least it proves that we're on the right track."

Reaching out to pick up the "Please Let Me Stay in Your World" spread on the ground, the spread page happened to be the last book cover, Ru Mi picked up the book, ready to wipe the dust, but was surprised to find that there was a note in the book cover.

For this unexpected discovery, Rumi didn't stay too long, and after taking a quick photo, he sorted it out and put it back in his table pocket.

"Let's go, let's go to the cafeteria and have a look."

At this time, it was already six o'clock in the afternoon in the mirror world, and according to Rumi's estimate, it was already the next morning outside, but I don't know if the so-called Wu Shao really has the ability to find here.

At the noon meal, they didn't eat peacefully, and they were naturally extremely hungry at this time.

The two of them came to one of the canteens, and found that there were a lot of people, and the entire canteen was basically full.

The canteen has two floors, they are afraid of trouble, so they did not run to it, after entering the door on the first floor, the rightmost is the window for cooking, connected with a long row, and on the left is a small supermarket, connected to the supermarket, is the place to apply for cards and charge cards.

Xiu Yin didn't understand the rules of the school cafeteria, but Rumi had gone to school after all, and everything was in the school cafeteria. Basically, they won't accept cash from you, and you have to spend money to get a card, otherwise you won't be able to buy anything.

Rumi took Xiu Yin to apply for a card, this card is not a real-name system, you only need to provide the student's name, a few classes in a few years.

After getting the card, the two of them ran to the right to line up, the dishes were very rich, Rumi casually played a set meal of two meat and two vegetables, and Xiu Yin only ordered three steamed buns and a bowl of porridge.

"That's what you eat? If we don't have enough to eat, we don't have the strength to investigate what the female ghost said, and my sister is still in their hands! ”

"It's okay, it's enough for me to eat, on weekdays in the mountains, the food is similar to this."

Since Xiu Yin said so, Ru Mi didn't say much, the two of them finished eating, Ru Mi turned on his mobile phone, and the time displayed on it was half past six in the morning, that is to say, now the world in the mirror is half past six in the afternoon.

There is still half an hour to go to the evening self-study, and the two of them are naturally not prepared to go back to the classroom in such a hurry like other students, but their investigation has just begun.

The two were worried about an accident, so they didn't plan to act separately, so Rumi took Xiuyin with him and prepared to search for clues.

"After every class, the teacher walks in the direction of the stairs, so I speculate that the teacher's office is upstairs, and we may be able to find some useful clues by checking them one by one."

Going up to the second floor, the second floor is basically the same as the first floor, but the classes here are eight and five.

Continue to go up, came to the third floor, on the left hand side of the door number hung the words "Class 10", on the right hand side there is nothing hanging, Ru Mi looked through the open door, all of them were desks, and at this time there was only one teacher inside, that was the first teacher they met today, the geography teacher.

Rumi knocked directly on the door and shouted a report, which obviously startled the teacher, and hurriedly covered the letter she had just seen with something.

"Come in."

When the two of them walked inside, Ru Mi whispered to Xiu Yin.

"Wait for the opportunity to act, find a way to drag her, and I'll look for clues."

The two of them observed and walked, and when they came to the geography teacher's desk, Rumi said tentatively.

"Teacher Ding?"

"Well, what's wrong with the two classmates?"

Sure enough, in the morning, Ru Mi noticed that in the lower right corner of the slide, there was a signature, called Lilac, and there was also a Lilac in the teaching list on the wall.

Ru Mi touched Xiu Yin with his arm, Xiu Yin is also a thoughtful person, and hurriedly stood up and said to Teacher Lilac.

"Teacher Ding, that's right, I have a question I want to ask the teacher, but I'm embarrassed to come alone, so I came with classmate Rumi."

"That's right, what's the problem?"

As a teacher, Lilac naturally likes students who are willing to ask questions, and Xiu Yin is naturally handsome, so it is definitely a good idea to let Xiu Yin drag the teacher.

"Teacher Ding, I'm curious, why are there five oceans, but only the four seas are recorded in the textbook?"

This question involves some secrets, but it is not a big secret, many people know about it, but everyone tacitly chooses not to know, looking at Xiu Yin's inquisitive eyes, Lilac can't bear to perfunctory him, so she began to explain to Xiu Yin some things she knows, about the last piece of sea.

Ru Mi also took the opportunity to start his "little action", the mobile phone was hidden behind his back, and he kept shooting, wherever there was anything suspicious, Ru Mi took all the pictures, of course, the most important thing was the secret on the table that was hidden by Teacher Lilac.

The scene when they came in, Ru Mi naturally remembered clearly, there was a book on the table, as long as you find a way to open the book, you will know what is hidden underneath, but the possibility of hard work outweighs the loss is greater, so Ru Mi is still willing to choose a more secure method.

Xiu Yin seemed to understand and listened to Lilac's explanation, and nodded incessantly, until Ru Mi gave him a look, and snorted at Teacher Lilac, Xiu Yin immediately realized that Ru Mi was going to transfer the teacher away.

But how easy is this, Xiu Yin can't even deceive people, and he really wants to know this question, otherwise, I'm afraid his face would have turned red a long time ago.

There was no way, I could only try to divert the teacher's gaze, Xiu Yin unconsciously, constantly moving a little bit by little, and Teacher Lilac's gaze also moved.

Rumi's hand approached the book little by little, slowly opened the book covering it, and only glanced at the things below, and then leaked a shocked look, looking at the thing in disbelief, and then at Teacher Lilac.
