In this world where appearance is justice, being handsome is really useful.

Gao Yuan has always thought that Yang Yi is a very ...... Indescribable people.

Gentle and elegant, handsome and chic, Gao Yuan could think of good words on Yang Yi's head, but Gao Yuan never pressed the words on Yang Yi's head without blinking, hiding a knife in his smile, turning his face faster than turning a book, and so on.

But it turns out that a successful spy, a spy without any background background, single-handedly snatched the revelation from the cleaner and killed the cleaner and the boss of the gray man, Yang Yi is by no means as kind and cute as he looks.

If it's really a human being, you can't look like it.

Yang Yi turned his face to look at Gao Yuan, he tapped his fingers lightly on the table a few times, and then he said with a solemn face: "Time is too tight, I don't know how long I can last, so let's make a long story short, now that I have turned on this communicator, the big snake people have suspended the attack, but I believe that the big snake people's attack will not stop for too long, if there is no next contact, we will eventually be killed by the big snake people, all of them here." ”

Gao Yuan nodded in agreement with Yang Yi's point of view.

"Please, there's a plan that's not complicated to come true, I just got the poisoning plan from the ram......"

After a pause, Yang Yi thought for a moment, and then he continued: "It is necessary to continue to implement this plan, because this is the only chance that we may convince the Great Snake People to give up the attack, and the only difficulty in continuing to advance this plan now is that it is impossible to establish a direct connection with the Great Snake People, Xinghe, I want to know, what is the principle of this thing, and is it possible for you to operate it." ”

Xinghe immediately said: "The technology of this communicator is very simple, it is to send a signal, because the human beings on the earth do not have this kind of technology at all, so wherever the signal is transmitted, it is the protected domain of the big snake people, but the communication method agreed between the big snake and the gray man is similar to the human cipher communication, how to achieve it I don't know, this communicator actually does not have the function of communication." ”

Yang Yi was surprised and said, "Don't have a communication function? ”

Xinghe thought for a while and said: "I'll give you a simple example, humans built a house and used diesel engines to generate electricity, you don't know who this house belongs to, but you know that there are people in it when you see the lights, and when you hear the roar of diesel engines, you must know that this neighborhood is human territory, not a herd of sheep or a herd of pigs built this house, can you understand if I explain it like this?" ”

Yang Yi immediately nodded and said: "I understand, the big snake people use their unique technology to mark the area that will not be attacked, but now the gray man and the big snake man can communicate directly, if this so-called communicator does not have a communication function, then how can they contact each other?" ”

Xinghe thought for a moment and said, "I don't know. ”

Gao Yuan said with some curiosity: "Seagod, I want to ask, since you caught the gray-clothed people, why don't you get the answer directly from their mouths, but ask Xinghe?" ”

"Because it must be verified, the information obtained is not so simple, and the information obtained to identify the authenticity is also not simple, you have to understand that the gray man is a secret organization, their high-level are all trained in anti-interrogation, for an ordinary person, you may use the simplest way, a few minutes to get the correct information, but for the gray man, you think it is real information, it may just be the false information that the other party is trying to give you, this is very complicated."

Gao Yuan also felt that it was very complicated, this kind of true and false thing made him feel big when he heard it.

Yang Yi's fingers were unconsciously tapping on the table again, and then he suddenly said: "You mean, this communicator only transmits a signal, a signal unique to the big snake people, but it is not similar to the kind of signal that the earth uses to communicate, which can be directly converted into speech." ”

Xinghe nodded and said: "Yes, this kind of signal is similar to the noise of a diesel engine when it is working, it is just noise, because the radio signal caused by some kind of radiation is similar to a radio signal, and the earth does not have a language of such signals, and my explanation is a similar meaning that is easy to understand." ”

"This communicator is emitting a signal?"

"Yes."

"How?"

"Well, high-frequency electron collisions can be achieved with electricity, but the efficiency is very low, or with the basic energy of the big snake people...... How to explain it, humans can use batteries to make flashlights glow, but you don't think that batteries are very important things, and the same goes for this communicator, and the snake man dropped a flashlight with a battery on it to humans. ”

Yang Yi looked at the communicator again and said, "That is to say, this thing is the product of the big snake man, not the technology given by the big snake man, now I know that this communicator can transmit signals, so can it accept signals?" ”

Xinghe pondered for a moment, then she nodded, "Yes." ”

Yang Yi also began to ponder, and then he said in a low voice: "The communication between a high-level civilization and a low-level civilization can only be an accommodating high-level civilization to a low-level civilization, just as if you want to explain something, you must use words that we can understand, because there are no words in the language system, and there are concepts in the civilization system, which are incomprehensible to low-level civilizations, and at least a learning process is required." ”

Xinghe was quite surprised: "Yes, you understand correctly. ”

Yang Yi thought for a moment again, and said: "That is to say, the communication between the big snake people and humans is in a way that humans can easily understand, and the big snake people can easily grasp it, mathematics is the mother of science, and it is also the universal language of the universe, no, it is not a mathematical language, it is still too complicated, then using this communicator without communication function to carry out relatively complex communication requires a way that earthlings are familiar with, and it is a very simple way, such as ......"

Yang Yi's fingers tapped on the table again, and then he took a deep breath and said, "Morse code!" ”

Morse Code ......

After Xinghe muttered, she was extremely surprised: "Yes! Morse Code, a largely obsolete, but really effective way to get in touch. ”

Yang Yi continued to say indifferently: "It's not an agreed codebook, because there is no need, the big snake man only gave the gray-clothed man a communicator, and the gray-clothed person must quickly establish contact, they don't have time and need to build a new set of Morse code code, they just need to use the old one." ”

Xinghe said in a low voice: "Standard international Morse code? ”

"No, the Grayman's own Morse encryption code."

Xinghe frowned and said: "According to my understanding, the encrypted code is the password, and you still need to get the codebook." ”

Yang Yi smiled slightly and said, "The password of the man in gray is not a secret to me, because I was a member of the man in gray. ”

After finishing speaking, Yang Yi looked at the communicator in front of him and said, "If my judgment is correct, I just need to keep turning on and off this communicator, and use the frequency of the switch to transmit Morse code, well, it's very simple." ”
