Primary school students of all worlds

Wang Quan raised his head and stared blankly at the sky above: "Isn't there a pitch-black starry sky with twinkling little stars?"

As he was speaking, Illya's surprised voice sounded beside him. Wang Quan looked at the girl beside him in confusion. Illya picked up the ruby ​​wand and blocked her eyes with it, squinting her eyes and looking up.

"Student Wang Quan! That's not a starry sky, it's a wall! Those twinkling things aren't stars, they're glowing stones!"

"What! A wall?"

Under Wang Quan's stunned gaze, the Rock King nodded and said, "Those are radioactive stones embedded in the God's Wall. It was because of these faint lights that the ancestors of the Rock Clan evolved eyes."

"Wall of God..."

Wang Quan's eyes twitched as he looked up at the pitch-black sky. "If it really exists, how wide is this wall that blocks the sky?"

"Width? I think it should be described by girth."

The Divine Rock King spoke matter-of-factly, "The Divine Wall has a circumference of three thousand kilometers, and all the people of the Divine Rock Empire and the Wall Breaker Alliance rest here. The Wall Breaker Alliance has been trying to break through the Divine Wall and reach the outside, but when they came closest, they ran into the 'Myriad Dead Zone,' which is filled with death matter. And you humans—besides us Rock Tribe and the Thieves—are the third type of life to appear in the Divine Wall."

Elementary School Students and Underground Civilization: Chapter 116: How Many Steps Does It Take to Kidnap the Robot Girl?

Wang Quan rubbed his temples, combined with the only information currently available, and tried to use his limited imagination to imagine the current situation of the Shenyan Empire. He wondered if the "world" with a circumference of 10,000 kilometers mentioned by King Shenyan was possible?

"It seems we got one thing wrong from the very beginning..."

Wang Quan muttered, "Because I'm in a vacuum with no oxygen around, I think I'm no longer on Earth. But there's actually a place on Earth where gravity cancels out the other forces, resulting in a complete lack of gravity."

Miyu, who was standing by, finally reacted and said in a lost voice, "Are you saying that we are at the center of the earth now?"

"Well, I guess we are on Earth, but not on Earth. We are inside Earth, in the legendary inner-earth civilization."

Wang Quan bit his lip as he looked at the mecha girl in front of him: "This is a concept that should exist in science fiction, but I didn't expect it to actually appear before my eyes!"

"..."

Mana, who was standing behind the King, showed a confused look. According to her observation of the Tyrant's force field, the things that the Master could erase were not just mysterious, but also scientific fantasies. And just now, the Master said in person that this was a concept in scientific fantasy...but now the Rock King was still fine?

At this moment, Illya hurriedly took out the geography book and began to search, searching for records about the center of the earth. Miyu frowned and said, "But this is not right. The temperature at the center of the earth is not just 300 degrees Celsius, it's over degrees Celsius!"

The Godly Rock King, who had been listening silently, interrupted and said, "The environment was indeed very harsh before, but after millions of years of transformation, the current environment is the most suitable for the Rock Clan."

"Just like humans transforming places unsuitable for human habitation into steel jungles."

Wang Quan looked at the Divine Rock King and exclaimed, "Although humans have long since ventured into the starry sky, they can only gaze at the ocean floor in despair. As for probing the mantle beneath the sea, or even the Earth's core, the best they can do is use shock waves to give the Earth an ultrasound. No one imagined that humans have neighbors, and they're right under their feet."

"Neighbors? The Rock Tribe and humans..."

The Rock God raised his hand, and the spherical joints shining with metallic luster flexibly stretched out his fingers. Light beams shot out from his five fingers, and soon a translucent sphere gradually took shape in the air. There were many mini slimes inside the sphere, and mini elementary school students stood outside the sphere.

King Shenyan held up his 3D-printed model, looked at Wang Quan with burning eyes, and asked, "Is this the model of our world?"

"Do not."

Wang Quan shook his head and said, "71% of the sphere's surface is what you call Death Matter, and only 29% is habitable land."

"71% of the area is made up of Death Matter? Isn't this the Myriad Machines Death Zone?!"

The Divine Rock King murmured, "Many Rock Tribe members of the Wall Breaker Alliance have already broken through the Divine Wall, but they perished in the Myriad Machines Death Zone. However, even more Wall Breakers are heading towards the Myriad Machines Death Zone, because they firmly believe that as long as they break through the Myriad Machines Death Zone, they will be able to escape this cramped land with a circumference of only 3,000 kilometers and reach the Divine Realm with zero density and infinite space!"

As he spoke, the Divine Rock King excitedly stepped forward and grabbed Wang Quan's shoulders. He looked at the little boy with eyes blazing with sparks: "The Wallbreaker Alliance has worked hard for five thousand years just to stand where you humans have stood since the beginning! Please tell me, is the space there truly infinite?!"

"That's true."

Wang Quan said without hesitation: "The universe is still expanding, and no one knows when it will stop expanding, so theoretically, space is indeed infinite."

A series of clicking sounds and the sound of a graphics card running at high speed came from the body of the God of Rocks King. Although there was no way to see the expression on the robot's face, it was obvious that the God of Rocks King was not at peace at the moment.

"The Wallbreaker Alliance is right."

The Divine Rock King murmured, "The infinite space with zero density that scientists have imagined does exist. So, until now, I have been obstructing the Wall Breaker Alliance and even suppressing the Wall Breakers... am I wrong?"

"What is the Wall Breaker Alliance?"

Wang Quan asked hesitantly.

"A group of pessimists who think the world will end sooner or later..."

King Shenyan whispered, "The Divine Wall is clearly a sacred wall that protects our clan, but the Wallbreaker Alliance despises this great wall. They constantly want to go outside, to find the legendary paradise of infinite space. They believe that if they continue to stay in the Shenyan Empire, they will starve to death sooner or later."

"The idea of ​​drilling out is correct."

Wang Quan said in a strange tone, "A world with a circumference of 3,000 kilometers—I don't know what your food is, but in such a closed space, if all edible resources are consumed, the entire Shenyan Empire will inevitably starve to death."

"And this is a great thing."

Lihua looked at the Rock God in confusion. "Don't you feel suffocated by so many slimes in such a small world? I also felt that Hinamizawa was very small and suffocated, so I ran to the big city to have a look. Why is this natural thing being suppressed?"

"You humans don't understand the importance of the God's Wall to the Rock Tribe."

The Divine Rock King shook his head and said, "Not to mention the Wallbreaker Alliance constantly drilling holes in the Divine Wall. In fact, they have also caused a catastrophic disaster! Beyond the Divine Wall is not some infinite paradise, but rather a zone of death, filled with countless Death Matter. Some of the Death Matter currently in the Rock Clan's custody was seized from the Wallbreaker Alliance. Whether it's the desecrated faith or the Death Matter brought by the Wallbreaker Alliance, it has crossed the Rock Clan's line. The people of the Empire are furious and demanding that we smite the Wallbreaker Alliance."

After a pause, the Divine Rock King spoke excitedly, "But you humans, the ones who have always lived in what we call paradise, have proven that the Wall Breakers are right. There is indeed infinite space out there. They were just unlucky enough to have run into the Ten Thousand Machines Dead Zone, which covers 71% of the land. If they can find a way out without the Dead Zone, then the Wall Breakers will be the hope of saving the Rock Clan!"

"emmm..."

It is true that the space outside is infinite, but the nearest space, the "earth's surface", and the best space on the earth's surface have been occupied by humans. If the Rock Clan rashly runs there, it is likely to trigger a fierce conflict between the inner earth civilization and the surface civilization.

but!

Wang Quan looked at the excited mecha girl in front of him with a dreamy look, and recalled the Hinamizawa Mountains that he had just contracted recently. A large area there seemed to be still empty, waiting for him to stuff a group of hardworking and capable employees into it.

Elementary School Students and Underground Civilization: Chapter 117: Infinite Space

After teaching King Shenyan a lot of human languages ​​and having a long conversation with him all night, Wang Quan could no longer bear it. He could only apologize to King Shenyan who was still reluctant to leave. Then he lent King Shenyan the textbooks and some things he brought from home. Then, with the fantasy of pulling the robot girl to his own mine and assembly line, he slowly fell asleep.

While the primary school students were falling asleep one after another, the Godly Rock King was not idle. She packed up all the information she had obtained about humans and uploaded it to the cloud space. The 500 Rock Clan scientists behind her had already started heated discussions and research on this.

A few hours later, Researcher No. 514 crawled in front of the King of Rocks and prepared to report respectfully.

"Your Majesty, based on the textbooks and items provided by humans, I have compiled some preliminary information about them and established a preliminary model of the real world."

"Then bring it up quickly."

King Shenyan said urgently, "Tell me everything you know."

“First of all, it’s time.”

Researcher No. 514 said to King Shenyan, "Humans' concept of time is very different from ours. We use radiometric dating, which uses the rate of decay of radioactive elements to establish a scale of time."

"Ok?"

The Divine Rock King said in a strange tone, "The decay rate of radioactive elements doesn't change with physical conditions. If we don't use it to establish a scale for time, then what do humans use to establish a scale?"

"They rely on something called astronomical phenomena and natural laws to establish a time scale."

Researcher No. 514's voice trembled as he spoke, "King, do you believe this? Actually, we and humans all live on a planet called Earth! It's just that we live inside the sphere, while humans live on the surface. And one rotation of the Earth is one day. Besides the Earth, there are two other planets orbiting around it. The moon orbits the Earth once, which is one month, and the Earth orbits the sun once, which is one year."

"Well……"

The Divine Rock King said with genuine envy, "I can't even imagine what that scene is like. The Divine Wall is magnificent, but we've all been looking at it unchanged for millions of years. How can humans actually watch this massive thing moving for a whole year?"

After a pause, King Shenyan shook his head and said, "However, as long as we can find a way to break through the Myriad Machines Death Zone, we can also obtain this honor. So, tell me about 'space' corresponding to time."

Researcher No. 514 quickly said, "The data brought by humans doesn't contain any record of the infinite space we're so obsessed with. However, it says that the surface area of ​​the Earth alone is 5.1 million square kilometers!"

"How many did you say!"

The tone of the Divine Rock King rose in vain.

"My king, I've seen it hundreds of times, I can't be wrong."

Researcher No. 514 confirmed, "The Earth's area is 5.1 million square kilometers!"

"Humans are truly a luxury."

The Divine Rock King looked at the researcher with envy and longing, yet also a bit of confusion. "As a member of the Rock Clan, you should know what 5.1 million square kilometers represents, right? Why is it so peaceful?"

Number 514 looked at King Shenyan and spoke slowly, "King, the Earth you consider so luxurious is, in the eyes of humans, just a star orbiting the sun. The entire solar system covers an area of ​​approximately 90 billion square kilometers."

"9...9...90 billion square kilometers?!!!"

The chest of the Godly Rock Queen rose and fell violently, and then she raised her head and looked blankly at the God's Wall above her head. For the first time, the first time in hundreds of thousands of years, she felt that the huge empire could be so suffocating.

"Outside the solar system there is the Orion Spiral Arm, outside the Orion Spiral Arm there is the Milky Way, outside the Milky Way there is the Local Cluster of galaxies, and outside the Local Cluster of galaxies there is the Virgo Superlocal Galaxy!"

Researcher No. 514 spoke word by word, "The Wall Breaker Alliance is correct. Outside the God's Wall, space stretches infinitely."

King Shenyan briefly cooled the slightly overheated chip, then shook his head. "I've clearly understood how worthless the space we cherish so dearly is outside. But for now, let's take it one step at a time. Let's get to the surface first—and speaking of the surface, humans are our primary research target."

"King, according to the information recorded in books, the most advanced technology of mankind is about the same level as ours."

Researcher 514 explained, "They, like us, have reached the point of utilizing nuclear energy, but..."

Seeing No. 514's hesitation, King Shenyan said bluntly, "Just say it."

"Humans...are stronger than us, the Rock Tribe."

No. 514 solemnly addressed King Shenyan, "Humanity has 51 billion square meters to explore. Not content with that, they've even reached the moon, while we can only grope within this -kilometer-circumference wall. While both sides have mastered the use of nuclear energy, achieving a tie in cutting-edge fields, in other disciplines, our comprehensiveness is far inferior to humans'."

The Divine Rock King nodded. She had expected this, but she was still curious. "How different are we from humans?"

“Too many to describe.”

No. 514 shook his head and said, "Just talking about the periodic table, we thought the world only had 29 elements. The Wallbreaker Alliance brought in the Death Matter, expanding the world's elements to 30. However, humans have long since discovered that the world has 118 elements!"

"..."

The Divine Rock King unconsciously clenched her fists, and the great enthusiasm she had just felt for infinite space was immediately cooled by half... The Divine Rock Empire's hundreds of thousands of years of war history for limited space kept reminding her of what she might encounter once she went to the surface. Not only was humanity so powerful, but it was also in their home turf. If they had any intentions towards the Rock Clan... she didn't dare to think about it.

"King, you are the only one in the empire who has come into contact with humans. Do you think humans are dangerous?"

The researcher asked curiously.

"Everything is fine."

The Rock King whispered, "Not only do those five humans have short lifespans, but their physical strength is completely incomparable to the Rock Tribe. It makes one curious how they're still alive—except for Rika Furute. She holds a full bottle of Death Matter and is the most dangerous of the five. Fortunately, they harbor no ill intentions, but rather harbor a surprising amount of kindness."

After a pause, King Shenyan shook his head and said, "That's enough for this report. I would like to cancel the wanted order for the Wall Breakers Alliance and request that their leaders come here to discuss how we can travel together into the infinite space."

"king……"

Seeing the researcher suddenly become hesitant, King Shenyan felt inexplicably uneasy: "What's wrong? Just tell me what you want to say."

"I suggest raising the wanted order for the Wallbreaker Alliance from A-level to S-level."

The researcher hesitantly said to the frowning Divine Rock King, "Infinite space is indeed real, but if the information provided by humans is correct, it will also be the burial place of the Rock Clan."

Elementary School Students and Underground Civilization: Chapter 118: Is the forest blasted by mushrooms so terrifying?

Wang Quan woke up in a stimulating light that flashed red and blue. He opened his eyes with some difficulty and saw the mecha girl flipping through her books beside him.

"Divine Rock King..."

He squinted his eyes uncomfortably: "What's going on with this light?"

"Please don't mind, distinguished guest."

King Shenyan shook his head and said, "This is just the alarm light, it will stop soon."

After saying this, King Shenyan looked at Wang Quan, who was feeling uncomfortable, strangely and asked, "Will humans feel uncomfortable with such light?"

"A little bit."

Wang Quan nodded, and asked with some concern: "Alarm? Did something bad happen?"

"..."

After a moment's silence, King Shenyan looked at Wang Quan and whispered, "This is a wanted order. The entire Shenyan Empire is mobilizing to capture the members of the Wall Breaker Alliance. Unlike before, when they turned a blind eye, this time they're aiming to completely annihilate the Wall Breaker Alliance."

"Eh?"

The elementary school students who had just woken up also heard what the Divine Rock King said. Lihua looked at him in disbelief, "Why? Slime, didn't you say it was your fault before?"

The Divine Rock King's face revealed a bitter expression not unlike that of a human: "I am not wrong. If I am wrong, it's not in this matter, but in my evaluation of you humans."

"Eh?"

Wang Quan immediately looked away feeling guilty. Could it be that he had fallen asleep thinking about the plan to kidnap the slime and accidentally said it in his dream?

"I used to think you humans were like mushrooms, fragile and weak."

Hearing this, Wang Quan interrupted Shenyan Wang with a strange expression on his face: "To be precise, we are as fragile and weak as insects. Please don't insult us by calling us mushrooms."

"There are no bugs in the Shenyan Empire."

The Divine Rock King shook his head and said, "But there are a lot of mushrooms."

"Ha, the Queen really knows how to joke."
