Japan. The city of Tokyo. Nerima area.

The clouds are rolling down in the sky, the town is gradually getting overcast, and the cold wind is bleak, and the weather is probably no longer suitable for outdoor sports.

Nobita opened his eyes in a daze, and he looked at his surroundings and realized that he was standing in the open space where he used to play as a child. The three steel pipes over there are still horizontal, stacked on top of each other, as if they will go on forever. Something seemed to be calling out his name, but the voice was separated by season after season, and when it reached Nobita's ears, only the broken sentences were mixed in the wind, and the "whining" sound of the cold wind became one, and it was impossible to distinguish them.

He knew he must be dreaming.

Since then, this scene has appeared in his own nightmares countless times and lingered.

He saw his childhood self, and at that point in time, he and Doraemon were training baseball in the open field. Nobita still remembers the whole transition: Fat Tiger with a bat, grinning and warning him that there would be a baseball game against the town next door on the third day. If Nobita drops the chain at a critical moment, what awaits him will be a fat beating.

Then, Doraemon volunteered to help him improve his baseball, and in his words - temporary efforts were better than no achievements at all.

And then ......

————

"Now, Doraemon, it looks like it's going to rain soon." The young self was very lazy, maybe he didn't want to practice anymore, but now he just had an excuse, so he was very happy, "While it's not down yet, let's go home quickly!" ”

"No, absolutely not!" Doraemon's voice has always been hoarse, and it would be especially funny for him to shout at the top of his voice, "Besides, you've always been like this!" Slightly~~ I gave up lightly when I encountered a little difficulty, and learning was also ...... Do you know that if you continue like this, you will definitely become a wasted person who can achieve nothing?! ”

Nobita remembers that in a series of tests this month, he scored three zeros in a row, perhaps these zeros made Doraemon feel a sense of crisis for him...... The words were involuntarily reweighted.

Doraemon pulled his hoarse voice and chattered and preached in the clearing. However, Nobita and he have been running in with each other for a while after all, and they all know what he will say and the meaning behind these words.

"It's not that exaggerated, Doraemon, you see......" Nobita threw down his baseball gloves, jumped over, and rubbed Doraemon's round head around (Doraemon's face is made of some kind of advanced plasticized material, which is amazingly elastic), "It's going to rain for the next few days, and the baseball game will definitely be postponed...... In contrast, school homework must be more important, right? Instead of practicing baseball here, why don't you go home and do your homework in one go! It's ~~~ That's it, right? ”

At the mention of homework, Doraemon's tone seemed to soften, but he still glanced at Nobita with some suspicion, and said to himself, "Do you really do your homework well...... After struggling with himself for a while, he finally made up his mind, let out a long sigh, and gave way, "Alas...... Well, that's all for today......"

"Great!"

"But! Be! Doraemon grabbed Nobita, dragged him to him, and said in an almost questioning tone, "When you get home, don't you make excuses to read manga or take a nap...... Like what's 'rainy days and naps are as inseparable as toffee and coffee'...... Excuses like that, NO~~! No way! Absolutely not! Do you understand? ”

"Yes~~~~" Nobita replied in a lengthened tone, and began to smile and collect the baseball equipment he brought.

"Ahhh......h......h

……

"Boom ————!!"

A space-time tunnel about three meters high suddenly exploded, and an icy blue light shot out from it. Almost instantly, Doraemon, who was still smiling a second ago, was hit by the light. Nobita knows that Doraemon is a robot, and he has a kind of qualification called "safety threshold". When subjected to an excess energy shock, the body will automatically fall into a cooling state and be forced to shut down for a round of self-maintenance. (For details, see the theatrical version of "Nobita's Treasure Island") All the micro-expressions on his face disappeared in this instant, and his pupils lost their luster, like a broken puppet.

"Plop—"

The 129.3-kilogram body fell to the ground, and the baseball in his hand rolled to the ground and rolled to Nobita's feet.

"Doraemon? Doraemon! What happened to you?! Nobita naturally panicked, and hurriedly threw down the bat in his hand and pounced on him. But no matter how he shook it, Doraemon's body was like a puddle of cold metal, exuding a "dead" luster, without the slightest intention of moving.

"Wake up, open your eyes......!!"

An inexplicable repulsion came, just lifting Nobita's young body open, rolling in the air, and then falling to the ground again. At that moment, he felt a piercing pain in his back ankle - the force seemed to have calculated that he didn't hurt him, but he still sprained his ankle.

The two figures slowly walked out of the space-time tunnel, and Nobita recognized their uniforms, which were space-time police.

"What do you want to do?!" Nobita yelled in his immature voice, he wanted to stand up, but the burning pain in his right ankle didn't allow him to do so, "Why...... Why do you want to do such a thing to Doraemon?! ”

The policeman withdrew the gun in his hand (presumably it released a shockwave that lifted Nobita away), put on a formulaic face, and said stereologically, "Hello Nobita, citizen of the 21st century." We are affiliated with the Time Police, T· P, is an official public servant of the federal government in the twenty-second century. Due to the frequent time travel, residents of different timelines have frequent contact, resulting in a certain degree of disorder between the timeline and the future causality law. The Robot Arbitration Association, the Temporal and Space Management Institute, and the federal government of the world have unanimously decided to take back all robots that serve across the ages, and from now on prohibit any private form of cross-time travel. ”

"The cat-type robot, Doraemon, was produced at the Matsushiba Factory, the production date was September 3, 2112, and it was moved to Nobi Daibita's house in Nerima Ward, Tokyo, and it has been recycled."

"No...... No! Wait a minute! Nobita didn't understand what he meant, but he knew that the two policemen would soon take Doraemon away, "You can't do this!" Doraemon him, he ...... He's not a criminal! He's my friend! ”

"All robots will be inspected by the Robot Arbitration Society, and will be convicted once it is confirmed that they have taught knowledge to the past world that should not have been taught." The policeman must have seen too many such scenes, and his expression was extremely numb, and he just repeated like a repeater, "Human citizen, you still have the right to appeal." However, please note that from now on, it will be considered a crime to travel through time and space without an application. ”

With that, he and his companions dragged one of Doraemon's arms, turned around and walked into the space-time tunnel.

"Doraemon ......" Nobita supported his body with his hands and barely climbed a few meters forward, tears and sweat mixed together, messing up his face.

"Doraemon ————!!"

He shouted in despair.

A thunderbolt fell out of thin air, followed by a torrential downpour.

————

“——！！”

Nobita, who woke up, sat up from the tatami mat abruptly, and almost at the same moment as he got up, his right hand pulled a bat mark from under the pillow with lightning speed. With a flick of his wrist, the dart came out of his hand, and with a "bang", it was firmly inserted into the door.

At half past four in the morning, everything around was quiet.

Nobita gasped twice, slowing down a little, and expelling the oppressive and suffocating sensation of the nightmare out of his head. Eight years have passed since Doraemon was taken away, but fragments of this memory are still lurking in his DNA. Every once in a while, he would dream of the scene of that day clearly, as if his own body would not allow Nobita to forget. The pain, the powerlessness, and the despair...... He will be remembered for the rest of his life.

"Ugh......" Nobita let out a long sigh and got up, pulling the bat mark off the door panel. If you get closer, you can see that there are already dozens of such small potholes in the door panel, all of which were thrown out by Nobita when he was "killing people in his dreams".

Without saying a word, he packed up the bedding and pillows, and hid the bat in the drawer of his desk. After doing this, Nobita glanced at the electronic clock, and it was 4:40 in the morning. "There's still time to ......" he exhaled, turned around, and walked towards Doraemon's closet.

There is a long wallpaper on it.

[Hanging Secret Base: The main body is a wallpaper, and after being pasted on the wall, a 50×50×50 three-dimensional space will be generated inside as a secret base. The inner and outer spaces are disconnected and do not interfere with each other. 】

It seems that because of the assembly work, the two policemen saw that the four-dimensional pocket was properly placed on Doraemon's stomach, so they didn't pursue it further. When Nobita dragged his sprained leg that day, limped home, and found the [spare pocket] that Doraemon left under the pillow, he already understood...... As long as you take advantage of it, you will also have a chance to meet Doraemon.

He's a man known as a "prop ghost......

It's just that it takes a plan, a long, long plan.

————

Nobita walked into the secret base, which has been transformed into a vast manor, and as far as the eye can see, the birds are singing and the flowers are beautiful. He had sprayed the ceiling of the base with glowing moss, which would create a light source that would wither every twelve hours and grow again the next day. Dragged its blessing, there is no difference in the time of work and rest here from the outside world.

Inside the manor, there is an open-air training ground, and Bruce Wayne is sitting on a bench. He was naked, covered in sweat, and the numerous knife wounds and gunshot wounds were particularly eye-catching. He looked like he was doing a high-intensity morning exercise, and by all indications, he woke up earlier than Nobita, who woke up.

"Good morning, Nobi-kun." Bruce didn't look back, but he heard Nobita's footsteps, "It's been very early today." ”

"Good morning, Bruce." Nobita smiled.
