"Huh..." The plane continued to snore sweetly, unaware that the blue mother star had risen. A ray of bright blue light flowed down, gently stroking Ranran's white face. It was also like a naughty child, jumping on William's body. Finally, they were awakened by the teasing. The car yawned and opened her eyes. Sophia the tabby cat got up too. Hagar the fan flipped on a switch, blew himself up, and then flexibly did a somersault. The party saw him blow himself backward to the ground and come to a steady stop.

William gave an involuntary thumbs-up and said to himself, "I wish I had a fan like this."

"Oh, really? Don't worry!" The fan said, "I know a grocery store owner who has the same type of fan as mine. The store should be somewhere more than ten kilometers at the main road. I'm sorry that I don't know the exact location. If you're interested, you can go there and have a look. Maybe you'll find something else!"

"Wow, really? Thank you very much for giving me such valuable information." Said William, bowing excitedly.

"You're welcome." The fan replied brightly.

"Thank you, Ms Sophia." Ranran said politely, then whispered in her ear, "Thanks for giving us free food and a night's stay."

"That's all right. I'm the one who should be thanking you." Sophia replied shyly, "It was you who helped me discover the origin of a series of strange things, even though it was done in a dream. But look at these!" She said, pointing to two extra objects in the corner.

It was a mosquito robot and a box full of gold bars.

"Wow! I didn't expect that what we got in our dreams could come true!" Cried Photon excitedly.

Ranran found everything they had found in the purple room.

"This is a magical room." William said with a smile, touching his stomach involuntarily, "I'm a little hungry. We would love to have another meal at your place, but time doesn't permit. We have to move on. I'm sorry."

"Don't worry." Tabby said, pulling out a portable disk and stuffing it into his clothes. "Here are some recipes for some main foods in my store. You can always follow this if you want. Don't starve yourself on the way." She whispered.

"Are you..." William was a little overwhelmed with surprise.

"Well, to tell you the truth, I've just opened and the store is getting more and more people, so I'm a little worried about the staffing now. And this mosquito robot is just taking care of my garden, but it's not going to solve my problem." Tabby sighed softly and looked out the window at the cafe. The street gradually became crowded.

Turning around, she continued, "A few days ago I could manage quite well on my own, but now I'm just as busy as a bee. Yesterday was a quiet day; I would have been up and opened the door on a normal day. I don't think there would be too few customers today. Oh, I wish I had some help."

She bent her head gently and looked at her watch. It's almost business time. "Get ready for a busy day, Sophia." She said to herself, hurriedly dressing and cleaning up, only to find, in surprise, "Hey, where's the fan customer?"

Everyone looked for them in a hurry. William called anxiously, "Mr Hagar! Mr Hagar!" But there was no answer.

"Where can he go?" He asked, puzzled.

"Can he have gone?" Natalie speculated.

"No way." Sophia answered firmly, "I know him well, and I know he would never just go away like this."

"But apparently he's not here." Photon said.

Then they heard the electric fan Hagariffin's voice outside the window, "Well, I need a robot now. My request to him is that he must be able to be a cook, and be a qualified, even top cook. He needs to be able to make delicious dishes fast enough. He must also have a good, considerate and gentle enough attitude to be able to speak politely to guests when serving food. In addition, he must be able to act as a security officer, who will be required to evacuate customers in case of danger. I have no other requirements. Can you produce it now? ... Oh, yes you can. How soon can you deliver it? ... Three days, right? Could you speed it up a bit? ... Two days at the soonest. OK, OK, two days. But please ensure the quality of the robot, because our user pays more attention to life and maintenance! ... No problem, right? That's great. Thank you! I'll meet you at Ridgestone's toy store in two days. Good cooperation!"

"What's he doing?" Ranran asked in bewilderment.

"Probably on the phone," Natalie guessed.

Sophia shook her head and replied, "No, no, no, he doesn't usually do it in such an inefficient way. I think he used 'have a talk'. Each user will have a fixed code, and when you want to contact each other, just press the corresponding module. Unless one is doing something extremely inconvenient, the system switches on automatically, and it's free of charge!"

"Wow, is it possible that all the residents here use it, Ms Sophia? It sounds superior." Ranran asked, interested.

"I think yes. At least it's common."

"Mr Hagar said robots were needed?" Said William to himself, puzzled.

"Did you hear him?" Ranran asked him.

"I'm not sure, but it sounds like it. He may be... Looking for a helper for you, Ms Sophia?"

"Really?" The tabby cat shouted in surprise and some joy when the fan came in. "Ms Sophia, you don't have to worry about helping hands." He patted the panel proudly, "The grocery store owner I know is able to contact the manufacturer of intelligent robots. I've ordered one for you, and it'll be delivered in about two days. It can do so many other things in addition to cooking! That means you only need to be busy for two more days and you will have the chance to relax!"

"Oh, really?" Tabby asked with a big smile.

"Don't worry, the shopkeeper is very honest and he will deliver the goods on time. I often come to your store, and seeing how busy you are every day, I have been thinking of adding a helper for you. OK, all you have to do is to wait!"

"Thank you very much!" Sophia hugged the fan tightly and gave him a big kiss. "It's my pleasure to have such a good customer as you." She laughed.

"It is our pleasure to have such a good shopkeeper as you!" Said William, bowing deeply.

"Oh, I'd better get going. It's a shame I can't spend more time with you. Many guests are still waiting for me!" Tabby cat hurriedly picked up the key, ready to go out. The others followed closely behind.

They arrived at the cafe in a few minutes. Sure enough, there was a long line in front of the door. "Open! Come in, everybody!" Sophia the tabby cat picked up the key and unlocked the door. The line immediately sped forward and the customers filed in. A few diehard fans didn't get their seats, but they took out the small tables and stools they had prepared and sat down in a place that didn't block access. Some people just sat on the floor.

Outside there were more than ten meters of the tail of the line. Tabby made more than $300(conversed) in half an hour.

Silently watching the fiery business by the side, the party also showed happy smiles.

"She's really too busy." The fan looked at the busy figure in the cap and apron and said with some sympathy, "Really, I never thought her little cafe could attract so many customers."

"Why?" Ranran asked curiously.

A customer's coffee was already out of the oven, and the fan replied, "If you get the chance, you can come into any cafe. I can assure you that there is no coffee in any cafe that has this particular strong aroma. It's not just her special recipe -- she told me about it, and indeed I've kept it a secret -- but more important, I think, is her heart in it. I have been to countless cafes, but they just add cocoa powder to water and boil it. When I personally observed her coffee making process once, I found that there was much equipment and the process was extremely complex. She quickly mixes the freshest cocoa beans, milk with a strong aroma, and boiling water. She then quickly adds the recipe, stirring until each molecule is immersed in the unique aroma of the mixture before cooking. She would taste it after cooking it. If she finds it too bad, she doesn't hesitate to throw out all the coffee and start all over again. This makes it take at least five minutes to prepare a coffee, but its taste is absolutely unique."

"Well," William sighed a little sadly, "no one on Earth does that anymore."

"Earth? What kind of planet is that? Why can't I find it in the universe?" Asked Hagar, whose eyes were shining with excitement, at the sound of his most alien planet.

"It's not in this universe." William replied.

"What?" Hagar gasped, "So you're from another universe... ?"

"Yes, and we came through a five-dimensional space." Said Ranran, "We need to go back to our universe, but the energy core has no power. So we need to gather enough energy to get back."

From the first time the fan saw them yesterday, he thought they had an unusual history. He did not know their true origin until today.

"It's unbelievable, really unbelievable!" He exclaimed in admiration, "You earthmen have such advanced technology?"

William answered, "We don't really have it all. The technology, which my father had just developed, was not released to the public because it needed to be perfected in some details. While I wanted to try it, and I ended up in another universe."

"Oh, I see." Said the fan, looking at his watch. He had his own things to do. "I've got to go, everybody. I am lucky to meet you. Bye!"

"Farewell!" The party watched his figure disappear into a sea of faces.

"I think we should say goodbye to Ms Sophia, too." William ran over to say goodbye to the tabby cat.

"Dear friends, we shall meet again soon. And if you ever meet Mr Hagar the electric fan, thank him again for me! He really helped me a lot, so I want to express my gratitude to him in full!" William saw the bright tears glistening in Tabby's turquoise eyes.

"Farewell, Ms Sophia. If there is a chance, we will definitely come back to your cafe and taste your unique coffee."

Sophia hugged William, kissed him, and looked at him affectionately with her emerald green eyes.

"Bon voyage," She said, silently turning away and wiping her cheek with her hand. William turned around too. "Let's go," He said.

Reluctantly, they opened the door and went out. William looked back and saw Tabby in the doorway, waving her hands at them.

He could not hold back any more and let his tears gush out.
