Doraemon travels through time and becomes Nobita

A group of people swam behind Sofia. Jin Jia looked at the small fish and shrimps around them, scratched Nobita's palm and said.

"What a big fish! Look, Nobita!"

Nobita was looking somewhere else and only looked over when he heard the clicking sound.

Nobita said, "It's a whale, everyone please slow down."

Doraemon found a flat place, took it out, and made a circle with the waterproof rope.

Doraemon said.

"There's this waterproof rope. We can keep out the sea water by staying inside. Let's all come in and take a rest."

Everyone pressed the button and stood inside the waterproof rope. Doraemon took out a small prop house. Everyone else went in to rest, leaving only Nobita and Sofia outside.

Sofia looked at the separated sea water and curiously reached out to touch the water.

"How about Sofia? Isn't she amazing?"

Sofia nodded.

Then Nobita and Sofia walked in side by side. There was a table in the middle with a dozen seats around it, and a group of people were sitting there to rest.

Nobita and Sofia sat down, and Kara stood up, which was rare, and tapped Nobita's shoulder.

Ka La whispered, "Nobita, you must be tired. Let me give you a massage~."

Nobita just glanced at Kara and knew what she was thinking without saying anything.

Sophia said.

"Doraemon is just like our legendary sea god, Manatia."

Jin Jia said, "What is the legendary sea god?"

Doraemon listened curiously to what Sofia said next.

"My grandmother told me this. Whenever the mermaids are in danger, it will appear and use the Mermaid Sword to help us. That's what the legend says. It is said that our mermaid ancestors have been guarding the Mermaid Sword from generation to generation. But now I don't know where the sword has gone."

Lilulu said: "You don't know where Sofia's mermaid sword is?"

Sophia said, shaking her head.

"This is a story that has been passed down from 5,000 years ago. Some people say it is just a legend."

Luna said.

"Sophia, didn't you say that the patron saint was a giant? How come it has now become the sea god Manatia?"

Sophia put her right index finger on her chin and thought for a moment before saying.

"Legend? It's normal to have more than one story. Anyway, I haven't seen it."

Fat Tiger said.

"The legendary sword, it's really nice. It's so cool just thinking about it."

Xiaofu said that if the legendary sword was found, it would be a great achievement. Maybe he could propose to the royal family and marry Sofia.

The speaker may not mean it, but the listener may take it seriously. Nobita stood up and gently supported Kara, let Kara sit down and then spoke.

"Doraemon, let's go find the Mermaid Sword!"

"What are you talking about, Nobita? Where can we find such a legendary thing?"

Kara and Jin Jia raised their eyebrows and looked at Nobita. They thought that looking for the mermaid sword was fake, and proposing to the royal family was real.

Sophia said.

"Doraemon, can you do this? If you can help us find the Mermaid Sword, our mermaid tribe will definitely thank you."

“This, that…”

Doraemon was a little embarrassed, so Nobita came over and hugged Doraemon.

"Doraemon, please."

Doraemon glanced at Nobita and then started rummaging in his pocket.

"It's not this, nor that... I found the treasure hunting paper and the hidden heater."

Doraemon tore off a piece of paper and handed it to Sofia.

"Sophia, take this. It will give us some clues when we are looking for something important. The premise is that the legendary Mermaid Sword really exists. After all, how can we find something that doesn't exist?"

At Doraemon's signal, Sofia stood up, took the treasure hunt paper and placed it on the fireplace. A group of people stood up and walked over to watch.

Fat Tiger said: "It's displayed, come and have a look!"

Sophia read out the words on the paper.

"When the royal family prays sincerely, colorful lights will gather and the wish will come true."

Fat Tiger said with a confused look on his face.

"What do you mean, Xiaofu, do you understand?"

Suneo shook his head and Doraemon said.

"As long as you solve this puzzle, you can find the Mermaid Sword."

Shizuka said as she looked at the words on the paper.

"The royal family mentioned on the paper... is it referring to Sofia?"

Kara pointed at the small words on the paper.

"What is that word? I don't understand it."

Sophia looked over and said.

"This is the ancient writing of Akya Star."

Nobita said.

"Sophia, can you tell us what it says?"

Sophia shook her head.

"This is too ancient. I can't understand the text. Maybe my grandma would know it."

Doraemon said to comfort everyone.

"Everyone, think positively. The presence of text means that the Mermaid Sword really exists and is somewhere. As long as we solve this puzzle, we will definitely find it."

After dinner, everyone started to divide the rooms. Because there were too many people, Fat Tiger and Suneo lived in one room, Nobita and Doraemon lived in one room, Sofia lived in one room by herself, and the five girls lived in the other three rooms by themselves. Nobita ignored them while everyone else was lying in bed and sleeping.

Sofia sat on the bed and took off her headdress, looking at the ancient characters written on it that were the same as those on the paper...

"If it's grandma, maybe she'll know what it means."

The door rang.

"Sophia can I come in?"

"Is that you, Nobita? Come in."

Sofia opened the door, Nobita walked in and they sat on the bed.
