"The people in the past were amazing! You can make a tool that can fly through the universe............" Yuri said, looking at the food package in her hand that almost cost her life.

"I already have enough food, but I still have to go to such a dangerous place............ It scared the hell out of me! Qianhu recalled what happened before, and said with palpitations.

Go back to three hours ago............

Along the way, Chito drove a half-track car according to the map to a slope......

"Excellent! The next step is to climb the slope............ "she said, intending to continue while the weather is beautiful.

However, the sharp-eyed Yuri found something interesting............

"Chi-chan! There's a hole there! She called out suddenly.

"Holes?" Chiho looked in the direction Yuri was pointing and found a dark passage in front of the left side of the car

"Na! Let's go to that hole! Yuri suggested.

"But according to the map, if we want to go up, we should climb that slope!" Chiho retorted.

"But I'm a little concerned about what's ............ on the other side of the hole," Yuri continued.

"We don't have enough time to take a long detour! ………… That being said............ Let's take a look! Perhaps because Chinoha herself was also a little curious, she finally compromised with Yuri.

"Is the floating wave sauce coming?" Yuri asked the boy as she turned her head.

“…… I'll go too! After all, there are some things that are also time to look for! The boy said as he picked Nuko off the car and put it on his shoulder.

The trio entered a not-so-long dark passage from the hole they found, and in order to save fuel, they abandoned the lantern lighting and replaced it with a manual torch provided by the teenager............

"Na~~ Why do you want to see what's on the other side of the cave?" Qianhu asked.

"How so...... After all, the world is full of things that you don't understand, so you want to go to as many places as possible, don't you? Yuri said as she kept pinching the handle of the flashlight.

"Well............ That being said, it's unlikely that we'll be able to investigate the whole world, because human life is so short...... Correspondingly, the scope of reach is very narrow............" Qianhu said noncommittally.

"That's why people in the past would divide up and work together to investigate different places, didn't they?" The boy said as he followed the two.

"But this kind of division of labor and cooperation is no longer suitable! ………… There aren't many ......," Yuri said.

"You're right! …… That's why we need to read books, don't we? Because from the books, we will learn more or less things that we need to know but can't investigate............" Senhu said as he looked at the light that appeared in front of him.

"Oh! There's a bright light! Yuri exclaimed excitedly.

"Probably the exit has arrived!" The boy said.

"Na! What's that............? Yuri asked, pointing to the behemoth that appeared in front of her.

“………… I guess it's a rocket or something! Chinohe said after his eyes adjusted to the light at the exit.

"It's so big!"

"But it looks a little sloping!" Qianhu said worriedly.

"It must have been too long ago, and there was a problem with the fixed steel frame! Let's be careful! The young man said as he put his right hand above his eyes.

"Let's go check it out!" Yuri ran briskly.

"I've said you need to be careful!" Qianhu said helplessly after her.

The trio followed the passage to the intersection at the bottom of the rocket, and above them were four very large rocket thruster vents............

“………… The first time you saw it............ That's what the rocket looks like! Qianhu said with some surprise.

The lively Yuri followed the ladder on the wall on the side of the intersection to the platform above the passage and walked forward.

"You~~ Where are you going?" Qianhu followed and climbed the ladder and asked.

"There's a door over there!" Yuri replied.

"Really! Don't move without permission............" Chiho complained.

"That should be the door to the control room!" The boy was the last to climb onto the platform and said.

"Control room? ………… Do you control the rocket launch? ”

"That's right! Thousand households. The boy affirmed.

Yuri walked straight to the door and tentatively pressed a button on the side of the door......

The door slammed open with a few pieces of falling scrept ice, revealing an upward staircase............

The three of them descended the stairs to a room with many glowing orbs.

"Thousand households...... This is ......," Yuri asked Chiho behind her, looking at the glowing orbs in a circle in front of her.

"This is probably the universe............" Chido said with some uncertainty.

"The universe?"

"Look! Those glowing orbs show the position of the stars! Chiho explained.

"It's not so much the universe...... It should be the solar system in the universe, more precisely! The boy said.

"Solar System............ It's what the galaxy we live in! Qianhu said.

"And is this what the sun is?" Yuri asked, walking over to the largest ball of light in the middle.

"Yes! And then this is the ............ of the earth," Sendo said, pointing to the sphere in the third circular orbit.

"Is the sun bigger than the Earth?" Yuri was surprised.

"Of course! …… By the way, this little ball orbiting the earth is the moon! ”

"Isn't the moon a little too small? Doesn't it look like the sun? Yuri couldn't believe it.

"The farther ones should look smaller!" Chiho replied.

"Is that so?"

"Hmmm! All in all, as we can see, the planets of the solar system are constantly rotating around the sun, and moons such as the moon are revolving around their own planets. Chihu said, pointing to the galaxy in motion in front of him.

"........................" Yuri's little head began to smoke.

'Looks............ You really still didn't understand it............ Qianhu thought clearly.

"And what is this thread that stretches out of the earth?" Yuri asked, pointing to the lines that popped up from the earth.

"Huh? Did you just have this? Qianhu asked in surprise.

"No............ This one just popped up out of nowhere............ There are three ............ popping up in total," Yuri said, pointing to the three lines in front of her.

“…… One of them will soon be gone! Chito said, pointing to the shortest of the three lines.

"The second root is ............ here," Yuri found where the second line had disappeared.

"The third one looks like it stretches all the way to the ceiling!" The boy said, looking at the longest line.

"Where did you go?" Qianhu said suspiciously.

"It can't be the extension upstairs, right?" Yuri guessed.

“………… Let's go up and have a look! Chino, whose curiosity was aroused, said and took the lead up the stairs to the upper floor.

Upstairs is a room with a row of observation windows, from which you can clearly see the previous rocket.

"You can see it very clearly............ That thing called a rocket! Yuri said as she walked over to the observation window.

"Hmmm! It's clear......" Sendo said, looking at the several tubes connected to the rocket.

"What are rockets for?"

"You ~ Rockets are machines that come and go to the universe!" Qianhu explained.

"Huh? Is it just that people can sit in it and go to the universe? Yuri asked in surprise.

"That's right!"

"Maybe there's something hidden in the rocket! Like food and stuff............" Yuri said, looking at Rocket.

"Looking at the shaky ............ It's not going to collapse suddenly, is it? And there's nowhere to go............ "Qianhu said in embarrassment.

"Na! That place looks like it can be passed............"

"Where? …… Huh!? From there............" Chido called out in fear as he looked in the direction Yuri was pointing.

I saw a sky bridge hanging in mid-air, connecting the rocket to the observation room, and because of the long time, the sky bridge did not seem to give people a sense of security............ The squeaky bridge in the cold wind made Qianhu not want to step on it anyway............

"Na~~~ Chima-chan is also curious about what's in it, right?" Yuri egged.

“………… There is no ............," Senhe refused.

"Na...... Let's check it out! It's not going to collapse.................." Yuri continued to agitate.

“……………… Is it really not going to collapse? Qianhu asked cautiously.

“………… Probably ......," Yuri replied, somewhat uncertain.

“……………… Really! In the end, Chiho compromised.

"Great!" Yuri jumped for joy when she was allowed to do so.

"What does Fubo think? Are you going with us too? Chiho turned to the boy and asked.

“……………… It's just the two of you who still don't look at ease! I'll bring nuko with me...... If there's any problem, we'll let Nuko take us back to this room............" The boy said to Nuko, who had been wandering around the room since the beginning.

"It's still thoughtful! With NUKO, safety is guaranteed............" Chido listened to the boy's suggestion and felt that the flyover leading to the rocket was not as dangerous as it seemed before............

However, when Chiho followed Yuri and walked to the overpass through the escalator at the end of the observation window, the whirring wind on the overpass and the terrifying scene under the overpass reminded her of the fear of being highly dominated!

"Sure enough, it still doesn't work!!!" The brunette girl clung to the handrail and shouted............
