Primary school students of all worlds

[There's also a possibility that they simply don't possess the intelligence to communicate, or perhaps... they simply don't bother communicating with us?]

--------------------------

"Is it impossible for humans and aliens to even communicate...?"

Wang Quan looked at the 'quiet' slimes and said thoughtfully, "Even if they can't speak, since they have evolved eyes, they at least have vision. In that case, we can try another way to communicate."

After thinking for a while, Wang Quan looked around and suddenly found that the "Rapeseed Sword" he had placed in the living room for worship was also teleported here. He grabbed the Rapeseed Sword and then poked it towards the rock surface under him. He was about to use the sword as a pen, but he was stunned as soon as the pen fell.

Only then did he notice that the rock beneath his feet wasn't a normal rock color, but... iron ore?!

After being surprised, he temporarily put this new discovery behind his mind, and then the branch scratched across a large amount of iron-containing gravel and wrote 1+1=?

While the others were still puzzled, Miyu's eyes lit up. "Right, even if the languages ​​are different, mathematics is universally recognized! You're truly Wang Quan!"

After saying this, Wanyou showed an annoyed look: "But why didn't I think of that?! Could it be that being a magical girl for too long really makes you stupid?"

Li Xiaolang looked away guiltily. He hadn't expected this trick...

Illya, who wasn't doing well in her studies, looked depressed. "I don't think it's the magical girls' fault. It's the fault of those bad guys who suddenly show up and threaten to destroy the world when the magical girls want to study! If it weren't for these troublemakers, magical girls could still be excellent students!"

"Shhh."

Lihua gestured quietly to ask everyone not to disturb Wang Quan, and at the same time concentrated on writing down 2+2, 3+3, 4+4... and other mathematical formulas that even kindergarten students could understand.

But the slimes remained the same as before. Although they were a little agitated, they still did not make any reaction that could be "understood" by the elementary school students.

"Even mathematics, the universal language of the universe, is not possible?"

Miyu sighed: "It seems that the other party is just a group of unintelligent alien creatures."

Elementary School Students and Underground Civilization: Chapter 107: The Shocking Slime Empire

what are they doing!

No. 103 tried hard to control his emotions as he watched these creatures, which exuded an indescribable aura, pick up a long object.

It was something that had never been recorded in the database. The indescribable creature stretched out a long tentacle, and from the end of the tentacle stretched out five 'small tentacles', which took the long object that the Rock Clan could not understand even with all their wisdom, and then began to draw. While drawing, the indescribable creature was watching them with its 'visual radar'.

But could that really be considered a 'visual radar'? This thing, similar to the visual radar he was familiar with, yet completely different, made No. 103 feel fear and unease.

【They are trying to communicate with us! 】

[No. 103, we were wrong! It's not that the other party is silent, but that they haven't accessed our network transmission protocol at all. So look, the symbols they drew are the messages they want to communicate with us.]

Number 103 looked at the words sent by Number 104. From the trembling words, it could feel how excited Number 104 was, but...

Number 103 stared blankly at the inexplicable symbols drawn by the indescribable creature. What did they mean? What were they trying to say?

--------------------------

Wang Quan stopped writing 9+9 and looked at the slime that was still in a commotion and did not move further. Miyu, a classmate beside him, had already concluded that these aliens who did not even understand the universal digital language of the universe obviously did not have enough intelligence.

“It’s true that the language of mathematics is universal.”

Wang Quan did not make an arbitrary conclusion, but pondered: "But Arabic numerals are not interchangeable. Just like the number 0 in the Tang Dynasty, people would not equate 0 with zero."

Hearing this, Miyu was stunned for a while, then silently took out her wand from behind her and murmured, "Sapphire, I have decided not to be a magical girl for the next few years and to focus on my studies."

The sapphire wand suddenly flew up excitedly, clinging to Miyu tightly, begging Miyu-sama that there was no need to connect becoming a magical girl and becoming a fool, and not to believe in superstition.

“Although Arabic numerals are different, the meanings of zero and 0 are the same!”

Li Xiaolang also reacted and looked at Wang Quan excitedly. Wang Quan nodded, and then placed two stones next to the equal sign of 1+1, and then placed four stones next to the equal sign of 2+2, and so on...

Just when he finished the last equation of 9+9, 18 pieces of iron ores were thrown beside him. The one who threw the stones was Slime No. 104, who had already understood their intentions.

The four elementary school students were filled with an indescribable excitement. They could only high-five each other to celebrate. They really communicated with aliens!

"Master..."

Mana noticed Wang Quan, who was not sociable, and asked, "Are you unhappy?"

"Why should I be happy?"

Wang Quan rubbed his temple and said worriedly, "How I wish these slimes hadn't thrown 18 stones at me. It would be great if their intelligence was only that of a kitten or puppy."

"Forehead……"

Mana's eyes moved back and forth between the four excited elementary school students and the Master with the kitten-faced face. She didn't understand why there was such a big gap.

Wang Quan just looked at the four elementary school students with helpless eyes, who were unaware of the seriousness of the situation.

Li Syaoran, Illya and Miyu are still too young. Rika, who is also a reincarnation, has lost a lot of memory due to reincarnation and has been trapped in the countryside. Her mentality is similar to that of an elementary school student. These four elementary school students have too many unrealistic romantic expectations for the starry sky. Only he is considering the headache-inducing reality.

Although it is unknown why such a highly intelligent life form could evolve in a place without oxygen and weight and with a temperature of up to 300 degrees Celsius, one thing is beyond doubt. Judging from the number of slimes in front of us, they are undoubtedly ethnic creatures, and it is very likely that they have already developed the idea that "those who are not of my kind must have different hearts."

What if the slimes were malicious and attacked his friends? He couldn't accept the loss...

Wang Quan looked at Mana in embarrassment, but an idea that was hard to suppress emerged in his mind - could he kill all these slimes, who he didn't know whether they were enemies or friends, and nip any possible risks in the bud?

The next moment, Wang Quan shook his head repeatedly to get rid of the idea.

Seeing him all alone and pitiful, she flew over to become his card spirit. The dark magician girl who grew up with him was so kind that she would never agree to do such a thing unless she gave a death order. This also included Rika and the others...

Thinking of this, Wang Quan could only clasp his hands together and pray that Mana could find the coordinates of the earth as soon as possible and return to a safe home before any unforeseen risks occurred.

However, Wang Quan didn't know that his praying had been captured by the slimes' visual radar, and the image was directly transmitted to the lowest building in a city thousands of miles away. The image of the elementary school students was projected on a large screen and played in a loop.

Under the big screen are densely packed silent slimes, but this silence is only an appearance. The green data on the big screen that refreshes at an ultra-fast frequency is like a landslide.

【quiet! 】

A slime wearing a crown sat at the highest point and sent a message, but its message was soon drowned in the flood of information. As a last resort, the crown slime could only use the royal authority to ban all speeches at once. The big screen suddenly became empty, and the quarreling slimes turned their attention to the crown slime.

[With the supreme authority of Shenyan Empire 'No. 1', issuing Agreement No. 0]

The name of the Crown Slime appeared on the big screen in enlarged, bold, and trembling golden font.

[Block the news! At least until we know what the unknown life forms are, where they come from, and where they are going, no information about the unknown life forms can appear in the communication channels of ordinary residents, and the people of the Wall Breaker Alliance are not allowed to know about the existence of the unknown life forms!]

Ok?

The Crown Slime paused for a moment, then lifted the ban, but only allowed those with level 2 authority to speak, and soon a line of enlarged, bolded, and trembling silver font appeared.

[No. 1, an information blockade against the general public is already underway, but a blockade against the Wallbreaker Alliance is no longer possible. Their Opener airship is already approaching the location of the lifeform.]

"Then what are you still standing there for! Get the Defender out there as fast as you can!"

The golden font trembled and appeared on the big screen. The Crown Slime stared at the unknown life form holding an unknown long object, his eyes full of intense emotional fluctuations.

[We absolutely cannot let the Wallbreaker Alliance get in touch with the unknown life form before we do!]

Elementary School Students and Underground Civilization: Chapter 108: Universal Language of the Universe

Although both parties can communicate through mathematical language, the efficiency of this communication is so low.

Wang Quan watched a slime use stones to make a math formula. Although he couldn't tell what the *-like symbol written by the slime was, he guessed based on the number of stones that it should be a multiplication symbol.

"This shows what?"

Miyu came up and asked curiously.

"This shows that the other party has mastered third-grade knowledge."

As Wang Quan was speaking, he also gave a multiplication math problem.

"Are the aliens only at a third-grade level?"

Illya said confidently, "Even I can solve squared powers now."

"Do not……"

Wang Quan squinted his eyes and said, "They're just trying to verify our skills. The slimes want to know if we've mastered third-grade knowledge."

"Being underestimated?"

Illya angrily said to the slime: "Who are you looking down on? We are fifth graders!"

"The other party can't hear you, Illya."

Miyu speculated, "Because they live in a vacuum, they can't speak, so there's no need for them to evolve organs like ears to receive sound... But since slimes are a group, they must need to communicate, right? How do they communicate? Pheromones?"

"There won't be pheromones in a vacuum, right?"

Wang Quan looked at the slimes thoughtfully: "Miyu, imagine what you would have to do if you wanted Illya to hear you without being able to speak."

Miyu's eyes lit up, and she suddenly realized, "The other party is a mysterious civilization, and can use magic to communicate directly, right?"

"..."

Wang Quan looked at Meiyou awkwardly. "I was trying to talk about texting. What's wrong with you, Meiyou? I remember you as incredibly smart, capable of solving university-level math problems!"

Miyu lowered her head, a rare occurrence, and said weakly, "I've been obsessed with magical girls for too long, and this happened accidentally."

Illya stared blankly at Miyu, who was told by classmate Wang Quan not to watch so many cartoons in the future. It was the first time she saw Miyu looking so embarrassed. Could it be that being a magical girl for too long really does irreversible damage to one's IQ?

"Student Wang Quan."

Lihua looked puzzled at the slime as it began to solve math problems with four characters again. "I don't understand—how can this kind of problem-solving really help? We can't express the question we want to know with just math problems, right?"

"No, mathematics can be used as the universal language of the universe for more than just this purpose."

Wang Quan looked at the slimes thoughtfully and said, "For example, one minute is sixty seconds, and the speed of light travels one meter..."

“It takes 1/299792458 seconds!”

Miyu said seriously as if trying to save her dignity.

"correct answer."

Wang Quan nodded and said, "This way, we can communicate on the two most important elements, time and space... but this logic only applies to carbon-based life forms."

"Carbon-based life?"

Li Xiaolang looked at Wang Quan blankly.

"Well, I doubt these guys are carbon-based life at all."

Wang Quan rubbed his temples and said, "This damn place isn't a place where carbon-based life can survive. As far as I know, there's only one kind of life that can survive in a place like this where the outside world only reaches 300 degrees Celsius. They're most likely another theoretical life form, 'silicon-based life.' Of course, these slimes could just as well be robots. Real life is hiding thousands of miles away."

"Silicon-based life?"

Miyu's eyes widened. "That's just a hypothesis proposed by some scientists. Isn't it said that it's theoretically impossible?"

"As far as Earth's environment is concerned, there's really no soil suitable for the birth of silicon-based life. Even if it were to arise by chance, a heavy rain would wipe out the entire silicon-based lifeform... But if it were an alien planet suitable for the birth of silicon-based life, it shouldn't be a problem. Uh, why are you all looking at me like that?"

Wang Quan looked at the four confused little faces in confusion.

“Because I don’t understand…”

Lihua said honestly, "After all, we are not as smart as you, Wang Quan."

“No, it’s not a question of being smart or not.”

Miyu looked at Wang Quan with a slightly bewildered expression. "Because even I don't understand what Wang Quan is talking about. This kind of extraordinary knowledge can't be summed up by intelligence alone. It's the domain of 'enthusiasts.' Could it be that Wang Quan is really interested in aliens, or even specifically researched them?"

"..."

Miyu's question was like a hook cast by a fisherman, and the memory of a young boy climbing onto the roof and looking up at the stars flashed through his mind. This memory exuded a dusty future, as if it came from a long, long time ago.

"No, I'm no longer interested in aliens."

Wang Quan spread his hands and said, "But that's irrelevant. What's important is that the most suitable communication method for humans (making sounds and receiving responses) is completely ineffective against these silicon-based life forms without ears or mouths. Slimes are likely the type that communicates through electrical signals, just like humans use communication software."

As he spoke, Wang Quan stopped the arithmetic problem he was working on, which had already reached the square of one variable, and looked at the slimes. The slimes also moved and separated into two sides.

Wang Quan realized that something was coming and squinted his eyes to look forward. Then he saw a

Then a scene that stunned the five primary school students appeared. They saw a "giant long object" without wheels, wings, or tracks coming from a distance with extremely low visibility.

"Is that Teng Snake?!"

Li Xiaolang said subconsciously.

"That should be a train? And a train that's floating in the air?"

Wang Quan, who was really shocked by the scene before him, clenched his fist unconsciously. The slimes were undoubtedly a highly developed civilization. At least before he, a reincarnation, traveled through time, humans had not built such a train that could fly in the air.

Because it was a vacuum environment, the huge monster in front of them came to the elementary school students with a "silence" that was completely opposite to its appearance. Then the car door slowly opened, and the slimes looked at the elementary school students eagerly while "crawled" towards the car door, looking back every few steps like puppies.

"This must be an invitation for us! Let's go over there quickly. Classmate Wang Quan!"

Looking at the inexplicably excited primary school students, Wang Quan held his forehead and looked at Mana.

The teleportation magic that locates the Earth...isn't it ready yet?
