Chapter 137 Preliminary Decoding of the Secret Key
"123"

Wearing headphones and protective clothing, Song Xizhu used light boards of different colors to represent different numbers under the instructions of experts.

Humans use basic mathematical languages ​​such as binary and prime number sequences as the starting point for communication. Mathematics is a universal tool in the universe, and any technological civilization must master basic mathematical logic.

Then he pointed at the alien. The mollusk pondered for a moment, then pointed at the whiteboard with its tentacles. A completely different color appeared on its body. Then he pointed at the blackboard again, and his body turned another color.
Prime number sequence aliens began to identify how their civilization represents numbers, and the communication between the two sides has made phased progress.

"yeah!"

An old academician excitedly did something that only young people would do, and several other academicians were so excited that their faces flushed.

Watching the preliminary exchanges, the scientists and academicians in the command department were even more excited than the officers in the army. Their faces were all flushed. This was communication with another civilization!
One uses sound to transmit information, and the other relies on the spectrum to complete the distinction between 0-9. The colors of 0-9 for aliens are defined by the University of Tokyo. In the future, any country that wants to communicate with alien soft-bodied people must follow the standards of the University of Tokyo. If the two sides can live in peace in the future, the alien mollusk can still return home.

After completing the prime number sequence, the next thing to do is to increase the amount of information and improve the spectral library through binary coding.

"Can we communicate with the other side using hydrogen atom energy level transitions?"

The time markers use hydrogen atom transitions so that both parties can understand the time scale and communicate more easily.

"No, the other party is just an individual. Without the assistance of a computer, it would be difficult. However, some universal laws of the universe can be used to speed up communication."

Scientists suggest using mathematics and universal laws of the universe, such as binary and hydrogen atom energy level transitions.

The initial communication is divided into two steps:
①. First, use the laws of mathematics and physics, such as prime numbers, binary, and the characteristics of hydrogen atoms.

②. Secondly, use images or symbols to convey information through bitmaps or coded images; then consider the modulation method of the optical signal itself, such as pulses or frequency changes.

These are all plans based on the fact that alien mollusks can see and express but cannot speak, and then use binary coding to compile a simple "answer machine".

This transponder can convert sound wave information into light pulses or electromagnetic wave signals, which alien mollusks can interpret based on their racial characteristics.

In this regard, Chinese characters have much greater advantages than English.

"Great! We're going to embed a spectrum analysis chart and a label of the human visible light range (400-700nm) in the message. Wait, what does it want to do?"

After the two sides communicated for several hours, suddenly the alien mollusk seemed to be stimulated by something. It curled up into a ball and stretched out like a rubber band, and its skin kept changing color.

“What is it saying?”

The commander looked at the changing patterns that he could not understand at all, and asked the experts with a headache. For officers like them who were professional in command, it was very painful to understand what the alien creatures were saying.

"Let me see, red, words, and green correspond to 01."

The spectrometer analyzes the spectrum emitted by alien civilizations, converts it into binary code, and then translates it into Chinese characters.

"It came out, and it's a little unhappy, but it's not clear what exactly it's unhappy about."

"Unhappy? Why?"

This can be considered as entertaining foreign guests. According to the hospitality of the University of Tokyo, prisoners should be treated well. If the aliens are dissatisfied with something, they can raise it. Whether their demands are met is another matter.

"Inquiring!"

The improvised optical pulse signaler flickered. Seeing the signal, the mollusk's surface shimmered, as if worried the humans wouldn't understand. It extended its nimble tentacles and tapped the nearby lifeboat, specifically the bullet holes. Pah! Pah! Pah!
After hitting the bullet holes a few times, the mollusk changed from a long strip into a lump again. This mollusk is very convenient in changing its shape and can be called the slime of the biological world.

"Its meaning is a bit vague, but if you interpret its body language, it seems to want to meet the person who shot him down."

After expressing its meaning, the alien octopus no longer responds to human communication.

"Tsk, it's getting upset?"

Seeing that the aliens were not cooperating, they had no choice. Communication is a subjective initiative and cannot be forced. The problem was reported through layers of authorities and finally reached the top.

"It wants to see Changkong?" The leader looked at the report and raised his eyebrows.

"Yes, judging by its behavior, it means it wants to see Changkong."

The commander glanced at the countdown on the big screen. It still had 3 hours until the Type 15 arrived in Hawaii, and even less until it entered the interference zone.
Why did it want to see Changkong? Perhaps it was because Changkong had shot it down twice and injured it once, so it was driven by some kind of obsession? Or was it some kind of tradition within the species?

However, communication has now encountered obstacles, and perhaps Changkong can break the deadlock.

"Since the alien wants to see Changkong, let him go and take a look. See what this alien friend wants to do and be sure to take precautions."

"clear."
-
"Comrade Liu Jun, we'll be there soon."

The helicopter's propeller stirred the air. Liu Jun looked at the 815A Yuheng starship getting closer and closer below. The four balls on it were very recognizable.

The 054B helicopter deck was occupied by alien lifeboats and mollusks, making it impossible for helicopters to take off and land, so the only way to get to the Luohe ship was by transport boat.

"clear."

Liu Jun indicated that he understood, then looked towards the 054B on the sea in the distance. On the helicopter deck, a small awning made of three-color cloth was set up on it, and underneath it was the alien mollusk that he had shot down.

So, it was shot down from the sky by itself, and then it went offline to find its true self?
In this strange thought, the helicopter landed on the helicopter deck of 815A. Liu Jun stepped on it, took a look at this most advanced electronic reconnaissance ship of Dongda University, and then was sent to the transport boat. After running wildly on the sea, he arrived at 054B.

When Liu Jun stepped onto the 054B, he saw the captain and a member of the Jiaolong Commando team who looked very capable waiting for him.

"This is a fist. It's responsible for protecting you. When making contact, be careful! You can't rule out the possibility that the other party might suddenly explode and injure you."

"understand!"

After thinking about how he should respond if the mollusk exploded and hurt someone, Liu Jun saw Song Xizhu standing beside him.

"Are you here too?"

"I'm here to help," Song Xizhu, wearing a mask, continued, "Be careful."

"Don't worry, we have many people."

His words made Quantou's face tense up, revealing the same expression as VV.
