Doraemon travels through time and becomes Nobita

Bepura persuaded Jinjia to come back, and Jinjia deliberately moved away from Kurt before starting to eat the cake.

"Listen to me, the Bepura Metal Manufacturing Machine that the three of us worked together to build despite financial constraints is finally nearing completion. Once it's completed, we can make Bepura Metal. The full metal developed by Dr. Hartman is indeed an excellent metal, but the materials needed to make full metal are gradually decreasing on this earth. One day, we will no longer be able to make secret props. However, as long as we have this machine behind me, no matter whether it is iron, aluminum, or of course full metal, any material can be converted into Bepura Metal. It can be said to be an extremely powerful machine!"

Kurt said: "This way, we don't have to worry about the problem of insufficient resources, and the secret props can continue to develop!"

"Yes, this way my name as the genius Bepra will be immortalized in history!"

Jin Jia looked at the two boasting and said calmly while taking a bite of sweet potato cake.

"Grandpa, you have already left your name in history, but it's a bad reputation."

Nobita looked around and said.

"Where are Fat Tiger and Suneo? Are they lost?"

Nobita's words startled Shizuka, while Doraemon said.

"They have transmitters on them, so there should be no problem. I say let's ignore them for now. Help me find the bell."

Doraemon looked ahead and saw a small snake-headed monster with something flashing in its mouth.

"Something is flashing!"

Doraemon ran over and stretched out his hand to search in the snake-headed monster's mouth.

"It's broken, Nobita Shizuka, I can't pull my hand out!"

Shizuka and Nobita hugged Doraemon and pulled him out with force. After Doraemon's hand was successfully pulled out, the space beneath the feet of the three of them turned into a hyperspace and they were teleported to a corridor.

"Hey, Jinjia's out of milk."

"Oh, there's really nothing I can do about you. Wait a minute, Grandpa. I'll go get it now."

Jin Jia opened the door and said, "I'm going out...", and happened to bump into Nobita who was sitting on the ground and Shizuka Doraemon next to him. Shizuka Doraemon and Jin Jia were both scared, and Jin Jia quickly closed the door.

"Kurt, your guests are in the basement, why don't you take care of them?"

Kurt took out his small tablet and was shocked when he saw the positions of the people. He quickly ran out through the side door.

Nobita stood up and knocked on the wall.

Shizuka said, "That girl, could she be the weirdo in the museum?"

Doraemon said: "No way..."

Nobita touched his chin and felt that the girl looked familiar.

Jin Jia thought about it in the room. The man sitting on the floor wearing glasses and a Sherlock Holmes suit looked familiar.

"Could it be an uncle? That doesn't make sense. There's a girl next to that boy..."

Nobita and his two companions came to the end of the corridor and saw the sun-making machine. Doraemon stepped on the cordon, which automatically sounded.

Doraemon said: "It looks like the alarm system here has been activated."

When the curator heard the alarm, he ran to the basement.

"What are you doing here? This place is off-limits!"

Doraemon said, "Director, we didn't come here on purpose!"

The curator looked at the men carefully and turned off the alarm.

Nobita said, "I'm sorry, Director, we are lost."

"How could you get lost here? Where's Kurt? Did he go out to slack off again..."

Nobita said, "Excuse me, Director, what kind of machine is this?"

The curator walked up to the three of them and said.

"You're talking about this. This is the prop that reproduces the development process of the sun, the prototype of the sun-making machine. This machine was developed by Dr. Hartman, who invented the Anywhere Door, and his research partner Dr. Bepra. However, during the development process, Dr. Bepra accidentally made a serious mistake and spilled a cup of coffee on the machine. Because of Dr. Bepra's serious mistake, the artificial sun began to run out of control. Later, the sun's enlargement was temporarily stopped by Dr. Hartman's timely disposal, but this artificial sun still has high energy in it, so it is very dangerous. Dr. Bepra, who caused this incident, not only had his prop craftsman's license revoked, but was also permanently expelled from the island. Dr. Hartman also investigated this incident and accidentally discovered a special metal and researched and improved it, and developed heavy metal. He used the perfect blocking system made of all metal to finally successfully seal the sun-making machine here permanently. In the end, all metal became the material for making secret props, and Dr. Hartman also won praise from people all over the world."

The three of them were a little surprised as they listened to the curator's long speech.

Shizuka said, "Director, what happened to Dr. Bepura who was driven away?"

The curator waved his hand and said, "Who knows? No one knows what he is doing there now."

Kurt followed the transmitter to the basement, and the curator was furious when he saw Kurt.

"Kurt, you are amazing. You actually left your guests behind. Where did you go?"

"I'm really sorry, Director. I just went to the bathroom for a while."

"I really can't stand it anymore. You always go out to be lazy for one reason or another."

The curator kept scolding Kurt, and Nobita, Shizuka, and Doraemon had to watch from the side. A bell rang throughout the museum.

"Ah, it's closing time. I'll let you go this time."

Kurt immediately expressed his gratitude and bowed to the curator to apologize.

"Alas, but I haven't found my bell yet!"

"Ah, speaking of your bell, I just checked the museum's security system and didn't find anything unusual. But DX is so sensitive to the system monitoring, it should be easy for me to avoid the monitoring. Anyway, the museum is closed today, please come back tomorrow."

Nobita said.

"Then we should go home too."

Shizuka said, "I still have homework to do."

Doraemon was lying on the ground, shouting that he would not go back until he found the bell, and the curator hurriedly comforted him.

"Don't worry, don't worry. As long as you have the invitation ticket, you can go back to the time of departure."

Shizuka was relieved after the curator said that, and the curator checked the hotel in the museum.

"The museum's restaurant is now full, and you're the only one at home, Kurt, so let them stay at your place for a night."

The curator said, looking at Kurt's embarrassed expression.

"Is there any difficulty?"

"No, no, please follow me."

Kurt found Fat Tiger and Suneo playing with giant robots in the robot museum.

"Everyone please follow me, this road leads to my home."

Kurt led the five people towards his home, and Jin Jia watched the images on the monitor screen.

"Are they going to Kurt's house? I'll sneak over to check it out at night."
