"It's so boring to sit here! Chi-chan ......" After observing the scenery outside the train window for a while, Yuri, who was a little tired, shouted.

"Hmm...... Yes......" Chido said as he looked at the picture taken in his camera.

"After all, it's been open for a long time! This tram ......," the boy said to Yuri with a smile.

"Na! Let's go a little further and see, shall we? Yuri suggested.

"That's fine!" Qianhu didn't care.

"I'm curious to see what's on this train!" The boy said.

The trio got back into the half-track and headed towards the front of the tram............

Sudden Sudden Sudden ............ The engine roared and echoed the roar of the train......

"Ahh I seem to have noticed something terrible! Yuri said suddenly.

"What?"

"Chi-chan, aren't we traveling on a running tram now......" Yuri said.

"That's right!"

“…… That means we're a lot faster than usual, aren't we? Yuri continued.

"Well! Let's just say that! Qianhu thought about it and said.

"Doesn't that mean we're moving at double speed now?"

"Nope! I'm afraid it's more than ......," Senhu said.

“………… It's rare for Yuri to think about something that has nothing to do with food. The boy said with a smile.

"Hey...... Maybe it's because I'm not that hungry! Yuri scratched her cheek and said.

"After all, you ate so much dried fish...... "Senhe said as he avoided the clutter in front of him.

"I can still eat it now!" Yuri said with a drool.

"No kidding......" Qianhu said speechlessly.

"Ahh But ............," Senhe said as if he had thought of something.

"What?"

"Continuing from the previous topic, we are actually traveling on a rotating earth, so the speed is actually a lot faster......"

"Na! How fast is that? Sen-chan. Yuri asked curiously.

"I don't know how fast it is, but all I know is that it takes a day for the earth to go around once............," Chiho said.

“1674km/h。” The boy said suddenly.

"What?"

"The speed of the Earth's rotation is 1,674 km/h." The teenager explained.

“…… Chi-chan? Yuri asked Chino.

"Soon! It's about dozens of times the size of this car......," Chido replied.

"Dozens of times! ………… It's amazing! Yuri closed her mouth in surprise.

"It's so fast............," Chido was also surprised.

"Huh! Wait, doesn't that mean we have to circle the earth every day? Yuri said in disbelief with her hands between her cheeks.

“…… If you want to think so, you can ......," Chiho could.

"That's amazing...... Yuri sighed.

The car kept going............

"Ahh It's a big robot............," Qianhe said, looking at the robot in front of the car.

"Stop, Chi-chan......" Yuri suggested.

"Hmm!" Chinohe turned off the car and pulled aside.

"It's broken!" The boy looked at it and said.

"It's easier to see robots when you get to this level, but most of them can't move like this!" Chiho said while sitting in the car.

“…… Yes! This is the corpse of a machine! It feels like the cemetery I've seen before, and this tram is also a moving black box! Yuri said.

"Moving tombs............ Where is its destination? Chiho muttered to himself.

"Oh! Chi-chan, look, look! What a big timer! Yuri called out from the side of the robot's torso.

"Huh? …… This shouldn't be a timer, right? Qianhu walked over and looked at it.

"So what is this?" Yuri was a little confused.

"This must be a clock!" Chiho concluded after careful observation.

The boy heard the discussion between the two and walked over to look at the back of the huge robot that had collapsed on its side in the train due to the shutdown.

"It's a clock, but it's probably a robot that works in a train! The kind of ............ with a chime function"

"What does the clock look like?" Yuri asked.

"Generally speaking, there are numbers or markers from 1 to 12 on the dial, and then this short hand represents the hours, and this long hand represents the minutes, and there is a more slender second hand............ The current time can be determined by identifying the position of the hour and minute hands. The boy explained.

"Huh? It feels like a hassle............"

"I see............"

Regarding the teenager's explanation, the two girls have different opinions.

"What time is it? Judging by this clock, ......," Yuri continued.

"Well! The clock was broken, but it looked like it was 8:47 a.m. judging from the hour and minute hands that stopped at it............" the boy said after careful discernment.

"Oh~~~~" Yuri didn't know what to expect.

"Alright! It's time to go, get in the car! Qianhu on the side didn't know what to think of and said suddenly.

"Ahh Wait............" Yuri hurriedly ran to the car body, and the boy was already sitting in the car.

"There's no point in being in a hurry on a moving train............" Yuri said as she sat down.

"Well...... Truly! Qianhu thought about it and said.

"I think that's what I've always done, and Yuri occasionally says something that makes a lot of sense!" The boy sighed.

"It's useless to be in a hurry on the turning earth!" Yuri continued.

"No, no, no! What are you thinking............ Hawkers! Stop and think about it, and that's right! ”

"But Ukiba-chan also looks like a clock!" Yuri said, gesturing at the boy's wrist.

"This?" The boy asked as he took off his gloves and revealed his bracelet.

"Why?" Yuri asked.

"Of course, it's because it's convenient!" Qianhu replied for the boy.

"Convenient?"

"In the past, people would also carry things like watches, so when they did something, they would have a score in their hearts." Chiho continued to explain.

"Huh~~? It sounds like a nuisance............ Anyway, I don't have anything to rush now............" Yuri said nonchalantly.

"But you ............"

Chinohe was about to say something when he was interrupted by a train that suddenly stopped......

"Ahh The door opened. Chi-chan, let's go! Yuri said, looking at the open tram door.

"You~ Wait, our destination is a little further ahead!" Chinohe stopped.

"Isn't it?" Yuri couldn't believe it.

"Indeed, as Chito said, we still have a few stops to reach our destination...... "The boy said, pointing to the row of lights next to the train door.

"What? These things are lined up like solid food......" Yuri wondered.

"That's where we are, right? But there's a lot more to it behind............" Qianhu said as he looked at the indicator light.

"That's right! We still have a lot of stops to pass before we get to the terminal! The boy said.

"Well! I had to continue to sit. Yuri sat down again with a helpless look on her face.

"Then, we also have a time limit for food! Although there are still many ......," Qianhe said, looking at the supplies on the body.

"Hmm............" Yuri responded blandly.

"It's really nothing............"

"After all, Yuri is a very optimistic person!" The boy said.

"In that case, let's go as far as we can while we still have food!" Yuri, who had been silent, suddenly stood up and raised her hands and shouted.

"That's right! How far can you go, how far you can go! Qianhu also echoed.

"Three of them together!" The boy said with a smile.

"Three of them together!"

The tram went on, and the three of them fell asleep because they were so sleepy, and by the time they woke up, they were almost there............

"It's been a long way............ "Chido said as he pulled the half-track out of the train.

"That's right! If we had to walk on our own, it would have taken us a lot of time! The boy sighed.

"Yes............ That's right! Yuri hasn't moved since then...... Obviously, he usually said so noisily............" Qianhu asked curiously.

"Looks like this thing has been making nice sounds intermittently since just now...... Yes! It's gone......" Yuri said, holding the radio to her ear as she listened.

"It can't be the radio waves, is it?" The boy called out suddenly.

"Airwaves?! Other words............ Anyone? Yuri hurriedly asked.

"Hmmm! Quite possibly! The boy also said excitedly.

"Chi-chan! We're going to meet people again! Yuri said excitedly.

"But how can you find it!" Qianhu asked.

"Towards the place where the radio waves are strongest, the clearer the sound of the radio, the closer we are to the radio waves." The boy said.

“…… Yuri paid attention to the sound of the radio ...... "Senhe explained."

"Hmmm! Wrap it up with me! Yuri said excitedly.

"It would be nice to be able to actually meet people...... Chihu said as he set off at Yuri's instructions............
