Nobita, quickly use your invincible treasure bag to think of a solution!

"Yes, you're right. I'd better do my homework first."

Nobita ran back to his house, carried his schoolbag over, and took out all the summer homework he had arranged.

With Nobita around and the strange time flow in Nobita's world, Nobita knows that he can finish his homework in this world and then run back to spend the summer vacation.

In this way, I don’t have to worry about being punished for not finishing my homework after school!

"Other me, please, teach me my homework!"

Nobita made a very incompetent tactical slide tackle and hugged Nobita's thigh tightly.

Nobita: "..."

Bianbian: “…”

After a short silence, Nobita stood up, picked up Bian Bian and said, "Well, Nobita, you find your summer homework first. I'll go downstairs and tell mother, aunt, and Doraemon to get to know Bian Bian first. Don't forget which homework you have to do. You like doing this kind of thing the most."

Nobi: "OK!"

After agreeing immediately, Nobita started looking for his summer homework, while Nobita carried Bianbian and walked downstairs.

"Come on, our little flat friend, I'll introduce you to the others!"

"Woo..."

Chapter 3 Your dog can do a backflip!

After introducing the little white dog Bianbian to his family, Nobita brought it to the reception room of his home.

At this time, mother Tamako has gone to the street to buy vegetables; father Shinsuke has an old classmate to meet and went out for a drink; aunt Kaori is busy in the store; Doraemon is busy dating with the "little Mi".

In the huge Nobita family, everyone has their own things to do, and at this time, only Nobita is still idle.

Oh, now there is Nobita and Bianbian, and Nobita also has the task of tutoring Nobita.

"Drink juice, eat snacks. Should I call you Bian Bian, or something else? The prince from the dog country?"

Nobita pushed the juice in front of the dog prince Bianbian and looked at him with a smile on his face.

"How did you know?"

Bianbian looked at the juice and snacks handed over by Nobita, sat back, crossed his legs, and asked back.

"How can I explain this good brother of mine to you? As long as he is kind-hearted and takes the initiative to pick up something from the street, that thing will cause a lot of trouble." Nobita drank the juice and moistened his throat. "I just happen to know some things about your country. For example, your country is located in Congo, which is central Africa. After millions of years of evolution, monkeys evolved into humans, and you evolved from primitive dogs into dog-headed people. But I don't know too much about you. I just know that you are a prince who was driven out by the ministers and drifted to Japan by chance. Do you have anything else to add?"

Nobita has revealed all of Bianbian's secrets, and Bianbian feels that he has no secrets at all in front of Nobita.

call!

Bianbian seemed to have let go of something, exhaled, and introduced himself: "I am Prince Kuntak, the son of the 108th King of Baowanhu of the Baowanhu Kingdom. I was forced into exile because of the usurpation of power by the evil minister Dabrandar. I think you know what happened next, so..."

Bianbian stood up and sat down in front of Daxiongtu, saying in a very respectful tone: "Please, sir, send me back to my country. If possible, I hope to borrow your magical power to help me regain the throne. Please!"

"My price is very expensive." Nobita ate the biscuits without saying anything more.

"I am willing to give you half of my kingdom, and you will be on an equal footing with me." Bianbian offered a very tempting benefit.

Unfortunately, Nobita doesn't buy it at all. There is no point in being the king of animal people. It was enough for him to be the king of the Rat Kingdom.

"Forget it, you are not worthy of being on equal footing with me. How about this? Use the gems you have as collateral. Also, I want you to interact with humans and do business with the flower growers. Don't say anything yet. I will provide you with the props for transformation and ensure that you all look like humans to outsiders. Anyway, it doesn't matter if a strange country suddenly appears in Africa."

With just a few words, Nobita tied this dog country to the chariot of the Flower-Growing Family. However, it would take some time for Bian Bian and the others to understand the excellence of the Flower-Growing Family.

"Yes, sir, I leave everything to you!" Bianbian had no objection, or he didn't dare to raise any opinions with Nobita.

Don’t look at the people in this dog country. They have evolved to the same level as humans. But after all, they are not humans and still have some instincts of wild beasts.

And just when Nobita revealed his identity, Bianbian's beast instinct told him to kneel down quickly, stop thinking, and just surrender.

As a man who crossed the sea relying on his beast instinct and finally arrived in Japan, Bianbian believed in his intuition very much, and this intuition saved his life more than once.

"Wear it. You can contact me anytime if you have any problems in the future. Come upstairs now and help Nobita and I with our homework. I will let him go to Congo when the time comes." Nobita threw a communication bracelet to Bianbian.

When she saw the white bracelet in her hand, Bianbian didn't refuse and put it on directly.

"Remember to put your things in the kitchen and come up yourself."

After giving the instructions, Nobita disappeared from where he was and appeared upstairs.

Bian Bian: "Wow! It's actually the ability to teleport. Do humans really have this ability?"

Bianbian was a little curious whether this adult was a human being.

However, before figuring out what happened, Bian Bian focused his eyes on the drinks and snacks on the table. He stood up straight, bent over and picked up everything on the coffee table...

In the bedroom, Nobita was explaining a problem to Nobita, and Bianbian was reading comics next to him while looking at the cards of Nobita.

"The sum of the interior angles of a triangle is 180 degrees, and calculating the angle of the obtuse angle is just a matter of addition and subtraction within 100..."

"Oh, remember."

"The dog you picked up is the prince of the primitive dog kingdom in Africa."

"Yeah, I see... eh? What did you say?"

Nobita's casual remark almost shocked Nobita. What does it mean to be a prince of the dog kingdom? Why can you say it so easily?

Seeing Nobita standing there in a daze, Nobita turned around and said, "Come on, Bian Bian, do a somersault for Nobita, and go!"

Bian Bian: "Fuck, go, ignore it!"

Nobita: “…”

At this moment, Nobita really wanted to call Shizuka and tell her that his newly adopted dog could do a backflip!

Oh, and it can talk!

……

After seeing off Nobita and Bianbian who could do backflips, during dinner, mother Tamako and father Shinsuke announced something very strange.

They were not at home for the next few days.

Shinsuke has a friend getting married in his hometown and invites him to visit and enjoy the local customs and culture.

Tamako had to go to the old house in Ota Ward, Tokyo to take care of her grandmother because she had a cold and injured her foot and there was no one at home to take care of her.

Uncle Yufu picked up a third-hand item that Nobita had used. He was busy running his own family and was too busy to take care of the elderly, so he had to ask Yuzi, who had nothing to do and had someone at home, to help.

"Nobita, Doraemon, do you two want to stay at home with your aunt, or come back to my hometown in Daejeon with me?"

Tamako asked Nobita and Doraemon for their opinions. She was a little reluctant to let go of the two children. Although both children were very independent and would not cause any trouble, it is better to be safe than sorry.

When Aunt Kaori heard this, she immediately pestered Tamako and said coquettishly, "Oh, sister-in-law, you know, my cooking skills are not good, and my food is not as delicious as yours. Can you bear to let the two children suffer with me? Otherwise, I will go with them and accompany you to Daejeon. I haven't been to other places for so many years. You won't refuse me, right?"

Tamako: "...Nobita and Doraemon, what do you two think?"

"Of course I followed my mother."

"I'm going to Daejeon with my mom too!"

Nobita and Doraemon both agreed to follow Tamako to her grandmother's house in Oota.

However, when Nobita went to Ota, he had to be busy running between two places. Taking care of his grandma would not be a one- or two-day job. Moreover, it happened to be Christmas at that time, so Nobita had to come back to accompany Shizuka and her daughter. He was very busy!

Fortunately, he is a true master of time management, so he doesn't have to worry about being too busy and neglecting anyone.

While Nobita was busy dreaming, he suddenly remembered something.

It seems like he had done something like that with grandma in the past. Even though it's been thirty years, there's no guarantee that grandma won't remember it.

Hastily!

Chapter 4 Grandma

The subway rattled and shook like a can of sardines. A large group of people squeezed in, and a large group of people went down, hurriedly and panic-stricken, like ants underground, living for the sake of living.

"See, Mother, I told you to use the Anywhere Door."

Nobita's head sank into Tamako's chest and mouth, with his aunt Kaori behind him, feeling both pain and pleasure.

No wonder there are train wolves. It is really the geographical advantage. With so many people, how can there not be train wolves?

Because of his short stature, Doraemon was squeezed against the railing, holding on to it with both hands like a frightened cat.

Yuzi felt Nobita's little head, her face blushed, and she said with a little tremor: "Well~ I'm doing this for your own good. I always use future technology. What if one day there is no future technology? What should we do?"

"Sister-in-law, you are too old-fashioned, aren't you? This is your first time as a human being, so of course you should enjoy yourself while you can." Kaori couldn't stand this canned-like subway either.

Fortunately, their subway journey only took half an hour, so they didn't have to suffer for too long, and the subsequent train journey would be much more relaxed.

Phew! X2

Just when people were crowded together, the subway suddenly shook and stopped. Both Tamako and Kaori breathed a sigh of relief.

This is our stop.

When the subway arrives at the station, a large number of people will get off and the subway will experience a brief period of relaxation.

However, before Yuzi and the others could breathe a sigh of relief and wipe the sweat from their foreheads, the crowd that squeezed in from behind pushed Yuzi towards the door again.

Yu Zi, who was originally leaning against the car door, suddenly faced the door. Her plump breasts were pressed against the glass and kept deforming due to the human force.

What’s even more embarrassing is that there is a pair of hands on the glass, which belongs to Nobita.

Just now, Nobita wanted to hold on to the glass to take a breath, but he was squeezed by the crowd and could only clasp his hands on Tamako's big cup. As the subway shook, the water bag kept shaking, and Nobita keenly noticed that his fingertips were a little wet.

"Little bastard, do you feel good?" Kaori's charming voice came from behind her ear.

Nobita suddenly felt his body go numb, knowing that someone had something on him.

Sorry, it’s my mother’s skirt!

……

After getting off the subway, Tamako and the other two felt the air was extremely fresh, but Doraemon only felt sore back and waist, and it didn't feel good to be a pendant on the railing.

However, what Doraemon didn’t quite understand was why Nobita and the other two had to go to the toilet?

It’s a pity that Doraemon doesn’t have X-ray vision, otherwise he would have seen that Tamako went into a bathroom alone, and Nobita and Kaori went into the same bathroom.

"Hoo!" X4

Only after they boarded the train did Nobita and his three friends finally breathe a sigh of relief. They only needed to wait two more hours to reach Daejeon, their grandmother's home.

As a model of thrift and frugality, Yuzi certainly would not let her children and sister-in-law eat the bento on the train. Who knows if it was made from rice that was contaminated by nuclear radiation?

So Tamago actually brings her own bento, one portion per person, which includes pork cutlet rice, curry rice, eel rice, and Doraemon's Dorayaki.

Although Tamako felt a little bad that others were eating bento while Doraemon was left eating Dorayaki alone, but after all, it was the bento Doraemon ordered himself, right?

The scenery outside the car window kept receding. At a glance, there was only snow-white land and withered yellow trees. The winter scenery was so boring and tedious.

When the four of them were about to fall asleep due to the shaking of the train, the train finally stopped. The loudspeaker in the carriage was announcing the station, reminding Nobita and the others that they had arrived at Daejeon Station.

After leaving the train station, this time Yuko didn't say anything like "using future technology will make me lazy". She obediently walked through the door that Doraemon brought out, followed him in, and arrived at her grandmother's house.

Looking at the familiar gate, the familiar courtyard wall, and the familiar house, Yuzi bent down, took out a key from under the flowerpot at the door, turned the door, and walked in with Nobita and the others.

Hearing the sound of the door opening, grandma limped out of the living room, trying hard to identify the people in front of her.

"Ahem, is that Yuzi?" Grandma coughed, holding onto the door frame, trying to identify the person who was coming.

"Mom, it's me. I'm back." After taking off her shoes, mother Yuzi hurried to support her grandmother.

After taking off his shoes, Nobita finally saw his grandma thirty years later.

How should I put it? It is somewhat different from thirty years ago. The knife of time has finally left its mark on grandma. Her hair is now mixed with white and black. Her face has more wrinkles and her body is a little hunched.

But the only thing that surprised Nobita was grandma's light blue tight sweater and the big cup under the sweater. The color was darker than before, but still firm.

I just rubbed it casually back then, is the effect so long-lasting?

Grandma's house is full of age and has no modern electrical appliances. It looks the same as the house Nobita saw thirty years ago. It is made entirely of wood and the floor creaks when you step on it.

Looking around my grandma's house, there are not many modern electrical appliances, such as televisions, refrigerators, and washing machines. It can be seen that my grandma is a nostalgic person.

After they followed their mother, Tamako, into the living room, Tamako began to introduce them to her mother: "Mom, this is Doraemon, and this is my sister-in-law, Shinsuke's sister."

"Mother, what about me?" Nobita pointed at himself.

"You still want to introduce him... uh, I really need to introduce him." Yuzi looked at Nobita's current appearance, and then looked at the photo of Nobita and his grandmother when he was three years old on the wall, "Mom, this is your grandson, Nobita. Although he has become more handsome and doesn't wear glasses anymore, he is really your grandson. And your grandson's grades are also very good, he is the best in the school."

When it comes to Nobita's achievements, Tamako can't help but show off.
