Doraemon travels through time and becomes Nobita

When everyone came to the beach, Nobita stood up and talked to a few people.

Little Harry also ran over and shouted.

"Your Highness, the Monster Fish Tribe has surrendered. We have won!"

Sofia laughed excitedly. She tightly grasped the mermaid sword that emitted a mysterious golden light and resolutely inserted it into the turbulent sea.

In an instant, the Mermaid Sword released a dazzling light, like a ray of hope, shooting straight into the depths of the ocean. The light seemed to have a magical purifying power, bathing the entire ocean in a holy glow.

Kara said as she looked at the clean ocean.

"Bravo!"

Jin Jia said: "This is the first time I've seen such a beautiful real ocean."

Fat Tiger burst into tears and said that the ocean was so beautiful and humans should always protect it. Suneo patted Fat Tiger's shoulder.

Doraemon said: "This is the true power of the Mermaid Sword."

Sofia said as she nodded to Doraemon.

"One day, we mermaids will return to Aqua with this sword, but this responsibility will be handed over to my daughter, because now the Earth is my home."

After Sofia finished speaking, she looked at Nobita. Kala pushed Nobita to get closer to Sofia.

"Your Highness, this is already a polluted planet."

Sofia looked at Nobita and smiled gently.

"No matter what, that is our homeland. We must never give up on it so easily. We must use this sword to make the polluted ocean clear again and restore the beauty of Aqua. This is the mission of our mermaid tribe. What do you think, little Harry?"

Little Harry half-knelt behind Sofia.

"Yes, Your Highness Princess."

Sophia said as she looked at the red gem on the Mermaid Sword.

“It’s great to meet you all, thank you for helping us.”

The group was on a small island, surrounded by seagulls calling.

All the strange fish tribes were locked up. Sofia led everyone to the city, and people around them were shouting.

Tongtong hugged Sofia's arm.

Dr. Medina said as he looked at the mother and daughter.

"Princess Tongtong is really a lot like Princess Sofia, but Princess Sofia has really grown up and become more responsible."

Undine looked at Nobita, Cara Lilulu, Sofia, Doraemon, Fat Tiger, Suneo, Shizuka, Luna, and Kinga and said.

"Yes, if Tongtong hadn't come, I would have planned to pass the throne to Sofia, but I know Sofia doesn't want to be the queen."

Undine brought everyone to the palace, where 108 dishes were laid out.

"Eat as much as you can, kids."

"Yeah, grandma is so nice!"

Tongtong sat on it, picked up a prawn and started eating, while Sofia walked over and scolded Tongtong.

"You can't eat without washing your hands. Come with me and wash your hands!"

"Mom, let me finish eating first!"

Nobita looked at the two of them and smiled. Undine walked up to Nobita and said.

"If the child doesn't mind, you can call me grandma from now on."

Nobita blinked, bowed to Undine and said, "Hello, Grandma!"

"Good boy, we are a family from now on."

Undine picked up Nobita and held him like her own grandson. Undine thought that Nobita was a good child and that she had found a good home for Sofia.

This made Fat Tiger, Suneo and the others laugh.

Fat Tiger said while eating.

"Nobita is so quick to recognize his relatives, but I can understand it. After all, Sofia is really beautiful!"

Sophia helped Tongtong wash her hands and then spoke.

"The Tongtong Mermaid Sword will be handed over to you from now on. From now on, I will rely on you to lead the entire mermaid tribe."

"I know, mom. I will definitely bring everyone back and make Akya Star full of life again. I hope mom and dad can come to see me one day."

Tongtong hugged Sofia, and Sofia kissed Tongtong.

"Got it, my dear daughter."

Sophia brought Tongtong back and saw grandma kept picking up food for Nobita, which made Nobita feel embarrassed.

"Don't be embarrassed, Nobita. This will be your home from now on."

Sophia blushed and patted Tongtong, asking her to go and eat first. Tongtong ran to Fat Tiger and started eating crazily, even faster than Fat Tiger. Fat Tiger was not convinced, so the two of them started a big eater competition.

"Grandma, what are you saying?"

"Sophia, you should stay with Nobita from now on. It won't be easy for the two of us to see you in the future. How about this, why not get married today and I will personally send you back to land tomorrow."

Sophia said, waving her hand shyly.

"Grandma, this..!"

"Don't say anything. I am determined. We mermaids don't care about those fancy things. As long as two people are willing to be together, that's enough."

Undine asked little Harry to go to the city to announce that Princess Sofia was getting married tonight.

“This is incredible!”

Little Harry ran out with a loudspeaker and shouted that the heir to the throne was Princess Tongtong, and Princess Sofia would get married tonight.

The people around were a little confused, but they still planned to go to the palace to congratulate in the evening.

In the evening, Nobita and Sofia were drinking the wedding wine while Tongtong was watching her parents get married.

Undine looked at the two of them with a smile on her face.

Kara said: "What's going on?!"

Xiaofu curled his lips.

"Such a grand occasion, I envy it!"

Several girls looked at Nobita, who was grinning so much that his mouth was about to burst out, and wanted to kick him.

Doraemon was comforting the girls.

"Everyone should calm down. She is a royal princess and she takes this very seriously."

Although Jin Jia ate delicacies from land and sea, they all tasted bland in his mouth.

Jin Jia said, "I can't eat this meal anymore!"

Then they turned their backs and Nobita and Sofia kissed in front of the entire mermaid tribe.

Then Doraemon took everyone away, and Undine promised to send them to land tomorrow, and Doraemon would pick them up using the Anywhere Door.

Undine and Tongtong personally decorated the wedding room for the two. Sofia and Nobita sat on the bed, both of them couldn't stop smiling.

Nobita hugged Sofia and felt that this scene was so beautiful, like a dream.
