Chapter 212： 1st transaction (2)

The interstellar communication equipment displayed by Poguya-Qi, the technical principle uses planetary gravitational waves, referring to the phenomenon of electric dipole motion generating electric waves, and the movement of planets in celestial systems around main sequence stars will also generate gravitational waves, drawing on the derivation method of electromagnetic waves, Gravitational waves propagate to distant space, and the measurement of distant space can be considered as adding a small term perturbation to the flat space. Using the weak field approximation method, let g?? equal to Min's metric η?? plus a small term h? ?, discarding the second type of Kjeldahl character in the sub-item part, ...

Li Yi saw the technical principle of the interstellar communication equipment displayed by Poguya-Qi, and immediately recognized the powerful functions of this equipment.

The existing communication technology of mankind, in the beginning, is long wave, which can propagate along the surface of the earth without any obstruction, as long as the power is large enough, it can travel far; then short wave, short wave has ground wave propagation and sky wave propagation, and the sky wave can be hopped. Thousands of kilometers; these earliest wireless communications are still useful today. Later, ultrashort waves, microwaves, and millimeter waves became popular and became the main battlefield of wireless communications.

It can be said that the development of wireless communication is from "low-end frequency" to "high-end frequency".

What about the future? It is still so! Or terahertz, optical wireless?

The existing 6G communication technology is far from meeting the needs of human civilization entering the interstellar era.

With the emergence of this interstellar communication device, Li Yi immediately clarified the communication method in the interstellar era.

Using gravitational waves for interstellar communication is an unimaginable thing. Using gravitational waves generated by planets and stars to achieve wireless communication in the entire galaxy is a technology that Li Yi could not have imagined.

Gravitational waves, in physics, are ripples in the curvature of space-time, propagating outward from a radiation source in the form of waves that transmit energy in the form of gravitational radiation. In other words, gravitational waves are violent motions of matter and energy. A matter wave produced by and change.

Einstein predicted gravitational waves more than 100 years ago. However, due to the small energy carried by gravitational waves, the intensity is very weak, and the absorption efficiency of gravitational waves by matter is extremely low. The advanced technological level of civilization is difficult to detect directly.

The biggest problem of human civilization is the global network and the interstellar communication problem after entering the interstellar era. Now, this device completely solves the problem of ultra-long-distance communication and global unlimited network coverage when humans enter the interstellar era, which is of great significance.

"I want this kind of interstellar communication technology, how do I trade it!" Li Yi looked at Poguya-Qi and asked with concern.

"I want all these drum instruments, and the music score of the matching drum instruments. We will exchange them." Pogoya-Chilion said loudly.

"No, no! It's so unfair! You want to exchange so many instruments and scores for me for one thing, and the value is not equal." Li Yi quickly waved his hand and refused directly.

"I think it's fair. My interstellar communicator belongs to the innovative technology knowledge of advanced civilization. Your drum instruments and musical scores are only entertainment knowledge. The two are not equal in themselves. I am willing to trade with you. You should be satisfied. , In addition, in the transaction mode, the interstellar communicator is an exclusive type, and your drum machine must be open." Pogoya-Qi said seriously.

"What do you mean!" Li Yi frowned, not understanding what Poguya-Qi said. After all, this was his first time trading knowledge.

Pogoya-Qi glanced at Li Yi unexpectedly and explained, "This is your first time to trade knowledge? This technology belongs to me, you can only use it, you can't trade it with others, and your drum instrument belongs to me. Recreational knowledge, I have the right to let go of them and make money through knowledge sales.”

After listening to Boguya-Qi's introduction, Li Yi immediately understood.

The interstellar communication technology shot by Pogoya-Qi belongs to the patent licensing, however, the musical instruments and music scores that he sold to him belong to the patent sharing.

In the case of authorized use of the patent, the copyright still belongs to the original copyright owner. After the patent is shared, both parties have the ownership of the patent, which has different meanings.

This ugly guy looks simple and honest, but his heart is really dark!

"No! Your trading conditions are too harsh. Cancel this deal! I'll find someone else to deal with." Li Yi's face turned serious and he refused decisively.

Hearing this, Poguya-Qi was in a hurry, and quickly reminded: "This kind of interstellar communication technology is only mastered by me. If I miss it, it will be gone!"

Li Yi didn't care and said with a smile: "If there is no such interstellar communication technology, what else can be done? Interstellar communication technology is a very conventional technology. I believe that there are not a few civilizations mastered! On the contrary, I have this kind of technology. Drums and musical scores should be unique to all civilizations, right!"

After a pause, Li Yi looked at Poguya-Qi and reminded with a smile: "Even if I can't find a suitable trading partner, I can still buy it in the knowledge public area. I don't lack this money, so you are considering the trading conditions. , don't talk about such unfair trading conditions."

Pogoya-ki opened his mouth, speechless.

As Li Yi said, there are so many third-level civilizations, and there are various interstellar communication technologies. There are also technologies that are more advanced than gravitational wave interstellar communicators.

However, Li of human civilization, the drum instrument and the matching musical score are indeed unique to their civilization. If he missed this transaction, the person who should regret it should be himself!

Pogoya-ki looked at the red drum kits with nostalgia, and a look of reluctance appeared on his face.

Looking at Poguya-Qi's expression, Li Yi's eyes lit up slightly, and he immediately became more confident in his own judgment.

There are countless civilizations in the star map. With all civilizations' understanding of the basic knowledge of the universe, the cognition of various scientific theories, and the technological trees that all civilizations are climbing, they will gradually tend to be similar, resulting in the removal of knowledge in the public area. In addition, the technology and technology mastered by many civilizations are highly homogenous.

In this way, when conducting private transactions, there are not too many targets to choose from. Such fierce competition will lead to low prices related to scientific and technological knowledge.

On the contrary, those "entertainment cultural knowledge" unique to the development of civilization have a certain uniqueness, scarcity and high value.

Li Yi has read a lot of information about civilizations, and suddenly, he realized that human civilization has a special advantage among these alien civilizations.

Most of these alien civilizations that have entered the interstellar era are a single ethnic group. Unlike the situation of human civilization, they are still in a state of scattered sand. Every country, every nation, and even a region can develop rich Local culture, various 'entertainment knowledge', which provide rich content for the entertainment knowledge base of human civilization.

This can help human civilization and trade for a lot of alien technology.

Seeing how Li Yi was thinking, thinking that he was going to cancel the deal, Poguya-Qi hurriedly asked, "What are the terms of the deal! Tell me!"

Pogoya-Qi looked at Li Yi with hatred, and had to admit that this guy was very cunning.

Even the exclusive and open types are not clear. At a glance, it is known that Li of human civilization is trading knowledge for the first time. However, he can judge the uniqueness of civilization's "entertainment knowledge".

Li Yi came back to his senses, with a confident smile on his face, and asked with a smile: "There must be many other technologies similar to the gravitational interstellar communicator, right? However, the musical instruments and musical scores of our civilization are only possessed by the entire universe. are unique and therefore cannot be estimated at normal transaction prices."

"Why are you talking about this! Hurry up and say your terms!" Pogoya-Chideng said urgently, in a hurry.

Li Yi nodded with a smile, and said, "I'll only give you three drum instruments and a three-point score!"

"Is it open?" Li Yi's voice was not old, and Pogoya-Qi hurriedly asked.

"No! It must be exclusive!" Li Yi said with a smile.

"It must be open-ended, or I won't trade!" Pogoya-Ki immediately turned black and said decisively.

"Yours is exclusive, mine is exclusive. If you are open, I will also be open! You decide! It's okay if you don't trade, I'll find someone else, you can think about it!" Li Yi said with a smile, A look of eating him.

With his judgment on the private transactions of all civilized knowledge, Li Yi has confidence in the knowledge transaction, so his attitude towards this transaction has become rigid.

"..." Pogoya-ki was silent, thinking about his cognition.

The drums of human civilization and the rhythmic scores made Pogoya-ki fall in love with them at once, and recognized their value very much.

If it is open, through them, a lot of valuable knowledge can be exchanged, which is much better than the interstellar communicator.

"Then it's all open, let's trade!" Pogoya-ki reluctantly confirmed.

"Okay! Are these three drums ok? War drums, waist drums, and this bronze drum!" Li Yi waved the drums he ordered to Boguya-Qi.

"I don't want these two, I want that one, and that one." Pogoya-Ki refused, taking off the war drum, waist drum, and replacing it with a set drum, and a big cylinder drum.

Li Yi nodded with a smile, and began to trade with Poguya-Qi. Under the witness of the Civilization Library system, the two parties provided transaction items. The transaction was estimated at 5 million star coins and 2.8 million star coins, and the total transaction size was 780 star coins. .

The 500 star coins are the estimated value of the gravitational wave interstellar communicator, and the 2.8 million star coins are the trading items provided by Li Yi.

After the two parties each paid 5% of the transaction tax, Li Yi paid 250,000 stars to successfully harvest the manufacturing technology of the gravitational wave economic communicator.

Confirming that the transaction was successful, Li Yi quickly opened the relevant manufacturing process.

With the current technological level of human civilization, it would take hundreds of thousands of years, or even longer, to rely on self-developed interstellar communicator technology. However, with this transaction, follow the detailed guidelines of the information. , the development progress can be increased by 99%.

The price paid is three drums and three musical scores, which is such a good deal, is there any?

After the transaction was over, after playing drums for a while and reading the sheet music, Poguya-Qi looked at Li Yi and asked, "Add a friend and look forward to the next transaction."

"Okay!" Li Yi nodded with a smile and accepted Poguya-Qi's friend request.

Soon, Poguya-Qi's screen went dark, and Li Yi continued to study the interstellar communicator.

...

The sky outside the window was already twilight.

Zhou Wenhui put the prepared meals on the table, and said to the pair of twins watching TV on the sofa, "Baby, go and ask your father to eat."

"I know Mommy."

The two lovely children agreed, jumped off the sofa, and ran to the study.

"Squeak-"

The door of the study was pushed open, Longfengti ran into the study, and saw Li Yi lying on the desk and sleeping.

The two little guys winked at each other, and the boy complained, "Daddy likes to lie. Every time he says he is busy with work, he comes in and sees that he is sleeping."

The girls didn't agree with it, and said with small mouths, "How can my brother say that about Daddy? Daddy's job is to sleep! Don't my brother know that these high-tech Daddy's are all out of sleep!"

After the boy heard it, the two brothers and sisters laughed together.

Then he tiptoed to Li Yi's front.

In fact, Li Yi woke up a long time ago. When the dragon and the phoenix entered the study, he just pretended to fall asleep and cooperated with these two little devils.

"Daddy!" the boy yelled.

The girl climbed up on Li Yi's body and grabbed his ears: "Get up! Mommy has cooked dinner!"

Li Yi opened his eyes and deliberately pretended to be a little embarrassed, "You two are annoying, and you actually disturb your father's sleep, should you be punished?"

As he said that, Li Yi tickled his precious daughter, and the cute little girl giggled in his arms.

The boys also laughed.

Until Zhou Wenhui's shout came from outside: "Husband, baby, it's time to eat."

The father and son finally gave up and went out of the study to eat.

Li Yanshun and his wife were already seated at the dining table. When they saw Li Yi coming out, their hair was a little messy, and they said with a tired look: "Li Yi, work should be done in moderation, but don't let your body wear out."

After listening to Li Yanshun's words, the little girl was dissatisfied and said: "Where does Grandpa have a job? He is obviously lying on the desk and sleeping."

Li Yanshun frowned and said, "That's why your father fell asleep too tired."

The little boy also became dissatisfied and said, "Grandpa, why are you so biased? Every time I fall asleep writing the homework left by Mommy, you say that I don't work hard, and you want Dad to punish me!"

"That's not the same!" Li Yanshun said with a smile: "Your father is my son You are my grandson, I love my son, and you love your father."

For a while there was laughter at the table, and the atmosphere was harmonious.

After dinner, the family rested, and Li Yi entered the study room again.

Li Yi needs to sort out the interstellar communicator technology he just obtained, and needs to translate it into human words, and then let Da Hei send it to the Xingyao Laboratory Center to establish related research projects.

Unconsciously, Li Yi was busy in the study for several hours.

When Zhou Wenhui came in, the LCD screen in front of Li Yi displayed various complicated equipment drawings and peculiar code symbols.

"Yi, what are you researching? Are you still asleep?"

Zhou Wenhui looked at Li Yi who was busy in front of the computer and reminded with concern.

Zhou Wenhui tried to glance at the computer screen, but quickly gave up.

Li Yi's research is not something she can understand. Zhou Wenhui is only asking habitually, and the purpose of coming in is to remind him to go to bed earlier.

"It's gravitational wave communication technology..." Li Yi explained happily.

Soon, Li Yi found that Zhou Wenhui was yawning, and after a while, she was sleepy.

Li Yi smiled warmly and said, "Are you here to tell me to sleep?"

Zhou Wenhui smiled sweetly, took Li Yi's arm, and said affectionately, "The four little guys are sleeping, you should rest early too!"

"It's hard work, I'll treat you well at night." Li Yi nodded with a smile, and approached Zhou Wenhui in high spirits and said.

Hearing this, Zhou Wenhui's cheeks flushed.

Li Yi got up with a smile and followed Zhou Wenhui to the bedroom.

With a "bang", the door to the bedroom was tightly closed, and there was a faint 'scream' from inside, which seemed like nothing, like joy or sadness, ... .
