"Dream machine?!!!"

Hoshino was shocked.

Isn't this a key prop that appeared in the theatrical version of "Nobita and the Fantasy Three Swordsmen"?And now this important prop is placed less than two meters behind him!

Without thinking too much, Hoshino can guess that this is probably the big adventure that Nobita and Doraemon will experience soon.

Hoshino dare not say that he is [-]% sure, but he is always [-]% sure.

"Dream machine? What is it for? Is it a prop that allows people to make any dream?"

Nobita said suddenly, with doubts in his tone.But the guesses spoken out are almost indistinguishable from the correct answers.

For this point of Nobita, Hoshino still admires it, Nobita is quite talented in this aspect.

"Nobita, you are right, but you are not quite right."

Doraemon finished eating the dorayaki in his hand, put down the plate containing the dorayaki and said to Nobita, there is no taboo about the existence of an outsider like "Hoshino".

"The dream machine can indeed make people dream, but it can't make people have arbitrary dreams. If you want to have a dream created by the dream machine, you must use its exclusive tape."

"Where's the tape?"

Nobita looked around and found that the bedroom still had the same furnishings as before—a desk, a bookcase, and a closet where Doraemon slept, plus the dream machine on the ground.

Besides, Nobita didn't find any place to put the tape.

"I don't need it now, of course I put it in my pocket."

Doraemon rolled his eyes helplessly at Nobita.

Hoshino quietly listened to Nobita and Doraemon's "flirting" and did not speak.

There were not many desserts on the plate that Doraemon brought over.After all, it is only used for entertaining guests to eat like snacks, it is not a meal, and it doesn't need much.

Hoshino ate and ate but disappeared.

"I should go home."

After seeing Nobita and Doraemon temporarily stop talking, Hoshino said in a timely manner.

It was almost five o'clock at this time, and it was time for him to go back.

As the host, Doraemon and Nobita will definitely not drive him away, but any normal person would not stay in someone else's house to eat and drink all the time, right?

Hoshino didn't want the goodwill he had just established in Doraemon's heart to be gone like this, the loss outweighed the gain.Although Doraemon may not mind how long he stays here.

It's just that even if Doraemon doesn't mind, he can't do it.

"Ah, Hoshino, are you leaving?"

There was obvious surprise on Doraemon's face.

After this, it is not long or short to get along with each other.Doraemon is not so alien to Hoshino anymore. When he called Hoshino, he called him "Hoshino" instead of "Hoshino-san".

"But it seems like it's time to go home..."

Doraemon immediately reacted, thinking of Nobita leaving school at 03:30, and went through a series of things behind.Hoshino seems to have indeed reached the time to go home.

"Then I'll use any door to send you home?!"

"Okay~"

Hoshino did not refuse Doraemon's kindness.

If he doesn't accept it, Doraemon will definitely feel bad.And as a "primary school student", normally he would not reject Doraemon's kind suggestion, right?

Why do you have to ask for trouble when you can "get home in one step"?

Hoshino picked up his schoolbag beside him and followed Doraemon downstairs.

After Hoshino put on the shoes, Doraemon put any door in front of Hoshino for Hoshino to use. After all, Doraemon doesn't know where Hoshino's home is.

It should be known that the use of any door must be that the user puts his hand on the door handle, and then thinks about where he wants to go before pushing the door of any door.

It doesn't mean that you have to do this to use any door. After all, any door is just a prop, and it's not that complicated to use.

It's just that if you open any door without thinking about anything, the place behind any door will be unknown.

If you open any door unconsciously, and what appears behind any door is the sun or a black hole or something... Then you really won the big prize that you can only win once in your life.

Although the arbitrary door will be reduced to ashes the moment it is opened, you probably have to... ahem.

Under the "guidance" of Doraemon, after Hoshino opened any door, what appeared behind the door was his own living room.

"Thank you, Doraemon!"

Hoshino greeted Doraemon and said goodbye.

Doraemon also waved his hand and said goodbye to Hoshino with a smile, and then the arbitrary door was closed by Doraemon.

Looking at the arbitrary door slowly disappearing from the bottom up, Hoshino was stunned for a while, and when he came back to his senses, he felt that everything he had just experienced was like a dream.

If someone had told him before, one day he would be invited by Doraemon to be a guest at home.Hoshino naturally doesn't say anything on the surface, but behind his back... ahem, he understands everything.

"Operation?"

Looking at the schoolbag he threw on the sofa, Hoshino seemed to think of something.

correct!He hasn't written his homework for today.

In his previous life, he stopped doing homework a long time ago, and he didn't even have the concept of doing homework.

But now that he has time-traveled into a primary school student, he has homework again.But Hoshino didn't feel very distressed, instead he felt an indescribable feeling lingering in his heart.

Picking up his schoolbag, Hoshino returned to his room.Then he took out a homework from his schoolbag and lay down on his desk to write.

The first thing to do is math homework. In Hoshino's opinion, math homework is the simplest homework. The tests are all about some extremely simple algorithms of addition, subtraction, multiplication and division.

Of course, there are still some so-called big questions.

It stands to reason that such things as the fourth grade should have been learned long ago.But that's what the teacher taught Hoshino when he was in class, and the math homework the teacher left today is also the same, it's really weird.

After all, in Huaxia in the previous life, this kind of knowledge was learned in the second grade.In the previous life of Huaxia, the second grade learned multiplication and division, the third grade learned fractions, decimals, perimeter and area, and the fourth grade learned the measurement of angles!

In Japan in his previous life, Hoshino didn't know the level of mathematics knowledge that Japanese fourth-grade elementary school students learned.But the fourth grade math problem in the world of Doraemon is just such addition, subtraction, multiplication and division!

In the original book "Doraemon Walking With Me", Nobita's math test paper once appeared in No. [-] or No. [-] middle school. On the test paper, Hoshino clearly saw that a certain math problem was such an extremely simple addition and subtraction problem!

Hoshino felt very incredible at the time.This also caused this incident to leave a very deep impression on him in his heart, so Hoshino was able to remember such a seemingly innocuous little incident.
