I am a master of light novels in Japan

But why does this happen? He hasn't seen anything like this. He has never encountered such a situation before, but this time he encountered it after returning from Hitoyoshi City. He always felt vaguely, right? What kind of evil ran into Hitoyoshi City was beyond the scope of his knowledge.

Hagi-Mura Bell quietly looked at Li Yan with a complicated look. He always felt that Li Yan today was particularly strange and in a very bad state, but now he seemed to feel a little heavy.

"Ah, by the way, when the professor severely reprimanded you, I can understand why you are so depressed. After all, I have also encountered such a thing. But today you are really out of state. It is obviously very simple. You can't do it, and it is excusable to be punished by Professor Ogura." Hagiura Suzu continued.

"Hey, Hagi Village, what are you talking about?" Li Yan asked in a daze.

"Huh? Did you forget that because you were late, you didn't answer three consecutive questions in the professor's class. The professor was so angry that he punished you to copy all the manuscripts from the university physics textbook to him ten times , Give it to him next Monday."

Hagiura Bell looked at him unexpectedly and reminded him.

"...Slow down, slow down, what's the situation! Copy that thick physics textbook ten times, no, it's all a misunderstanding, can I go back to the professor in front of him to answer the question again? Chance?!"

Li Yan's face turned pale suddenly, and asked Hagi Ling.

You know, that college physics textbook contains hundreds of thousands of words without saying...

After Li Yan listened to Hagi Village’s explanation, he understood deeply. It turned out that when he was transferred to Toyonosaki Academy, it was likely that the girl’s high school was exchanged for the same amount and came. After discovering his identity on his life line, it seemed that he planned to find clues from his school, but he performed very badly in class this day...

"No, take a leave tomorrow, we must solve this terrible thing as soon as possible..."

Li Yan looked at the thick copy of "University Physics 1" in his hand, thinking in pain.

In the afternoon, four o'clock exactly.

When he returned to the dormitory, Li Yan bought a lot of homework books, and he looked impenetrable and prepared to take the time to start working overtime today to copy the manuscripts of the textbook ten times.

Moreover, when he entered his dormitory, he saw the laptop he had been using to write novels, and he remembered that he personally promised the policemen that he would write the seventh volume of the novel within a month. Suddenly, his face began to haggard a lot, as if he was ten years old, and he felt deeply that his shoulders had more than doubled again, almost crushing his spine...

"No way...I definitely can't do it. Suddenly there are so many troublesome things that I really can't do..." Li Yan sat on the cushion in the living room, covering his face in pain, sadly Thought.

Suddenly, in the afternoon breeze, he heard the sound of paper hunting on the table in the living room. He let go of his hands and looked down, only to see a piece of paper held down by a water cup. A line of beautiful handwriting was clearly written on it.

"Who wrote this?" Li Yan was taken aback for a moment, picked up the paper, and looked over.

The note was a bit weird, and many of the handwriting became blank, as if it was suddenly erased after writing before, making Li Yan look at the note with care.

——(Blank): I’m sorry to disturb you, Xuechang Li, my name is (blank) and I am studying in (blank). I don’t know what happened. I suddenly appeared in your room, and it’s already It’s the second time. At the first time, I thought it was an illusion, but now I understand that it’s not an illusion. People who know you treat me like you, making me even more confused about what happened. I wondered Is there something unbelievable between us, is it an alien causing trouble, or is there some monster I encountered... But I also thought that it is very likely that we will return to the original state as before, so I wrote this message , If you see, please find me and we will exchange information together, hoping that such a terrible matter will be resolved.

As a result, the address and phone number under the note were all blank.

"..."

Li Yan suddenly fell silent. There is no doubt that this note is the female high school student who he forced to replace his life line. She was still very clever and left him a note, hoping to contact him by phone. Each other, uncover this mysterious event.But almost all information about this girl disappeared out of thin air.

Not only that, Li Yan tried to think of the girl's information, name, address, even school name and class again, all blank...as if it was erased by time and space suspiciously.

He tried to recall the appearance of that young girl, it was almost no effect, it was almost a mosaic...

"It's weird... why, why did it become like this?"

Li Yan blinked, shocked and curious.

This discovery made Li Yan even more horrified. After sitting in the living room and thinking for a long time, he probably had some guesses that time and space have the ability to remember. This is explained in physics, but basically They are all conjectures. In addition to the famous [Layered World Theory], there is also [Space-Time Memory Theory].

Although it is not clear why the phenomenon of [existence of interchange] occurred, and outsiders cannot see the changes in their appearance, almost speaking, the two of them have found anomalies in each other, and this is just their problem. .

But the strange thing is, why the information that proves to each other's existence is only erased, such as phone number, name, and even appearance are washed away on the carrier and in memory, instead of completely washed away...

It seems simple, when they restored their original body and life line, Time and Space simply denied that the two of them were confused about the main existence, especially each other's cognition and name...

"Name, phone, address, everything that can be communicated with each other will be returned by time and space, I can't contact her at all..."

Li Yan became silent, thinking.

A sunset shining on him, the room was peaceful and quiet. Li Yan looked at this room, as if it had been cleaned purposely. The efforts made by the girl were not denied by time and space, and it was intact. Keep the land here.

In any case, the girl who exchanged "existence" with him should be a trusted girl.Why didn't he want to quickly resolve this terrible phenomenon, so that this young girl would return to her own life as soon as possible, and each other shouldn't change their planned life course without authorization.

However, he didn't have a clear clue to solve this problem. At this moment, he, holding this piece of paper, fell into a dilemma and a little guilt.

All the so-called problems need to find the original source to start solving. This is the experimental knowledge of physics and the best way to solve the problems encountered in life.

"I only encountered such an incident when I came back from Kumamoto Prefecture. Sure enough... I need to ask them for help."

Li Yan closed his eyes and quietly planned his "Ice Breaking Plan" in that quiet room...

A phone call came to Takashi Natsume. After Li Yan explained the situation clearly, he asked Mr. Kitty to answer him after asking about Fujiwara Tago's physical recovery.

Soon, the cat teacher beside Takashi Natsume answered the call.

[Hey, Li, I heard that you have encountered any strange trouble again?

There was a glib and mature voice on the phone, and Teacher Cat came to answer.

"Yes, Mr. Mao, I did not find the problem this time, but after returning from Kumamoto Prefecture a few days ago, I suddenly encountered such a problem. In short, it cannot be explained by the known scientific level. It makes me think this phenomenon is a bit weird, do you have time to listen to me?"

Li Yan sighed slightly and asked through the phone.

[Well, you have been kind to me and Natsume several times before, but I still remember, if I can help you, I will tell you the solution, so what happened?

Teacher Cat freely agreed and said.

Li Yan then told Teacher Mao all the things in these days in detail, including all the important clues that he forgot after coming back here, and explained it clearly to Teacher Mao.

[So, it sounds troublesome, even if it is a big monster like me, I have never heard of it... No, last time Natsume was occupied by a monster who likes to play the piano, and suddenly he has a dual personality. Although somewhat similar, I always feel that your problem is not that the monster is trying to occupy your body...]

After the teacher cat listened, she began to analyze.

"I don't think it is either. I always have a dream... When I dreamed that I was soaked in the blood of Shura, my whole body was hot, like falling into a sea of ​​flames, painful, and when I exchanged existence, always It was early in the morning, when I felt pain, do you think these have any connection?" Li Yan nodded, and then he offered his guess and asked.

[If you feel it, there is indeed some connection. Our monster has never killed Shura, and even gathered all the surrounding land gods to reluctantly seal it, so whether its blood is harmful or not, there is absolutely no such thing. intelligence.However, Shura has eaten countless monsters, and its blood must have enough toxins, but didn't you kid inherit the merman's regeneration power?It should be said that there will be nothing wrong with you, let alone such a phenomenon of exchange because of Shura's blood...]

"Uh, won't you?"

Li Yan was taken aback and asked in surprise.

[Sura is a legend that threatens the existence of gods and monsters, but its power is not strong enough to change time and space, and... I always feel that the understanding on the phone is not comprehensive, but you are so far away.

Teacher Cat said lazily on the phone, although the analysis is very serious.

"Then, can you come and help me, Natsume, I remember that there is another monster named Sansino who can protect him temporarily, and I don’t want Natsume to be involved in this incident. You come to Tokyo alone to help How am I?"

After Li Yan thought about it carefully, he originally had a habit of not wanting to involve too many acquaintances in, but this time he encountered an extraordinary event, he had no idea, and this time another young girl was seriously affected by his daily life. Had to ask cheekyly.

[Yes, after all, you guy is in trouble... Ah, but it will take next week. My schedule is full for this week. There are many monster banquets and fine wines waiting for me to drink. In this way, anyway, it sounds, although the situation is serious, but it can't hurt you, it doesn't matter if you wait.
