Just like a foreigner, we had been negotiating for three days and three nights, and everyone was red and began to overdraw. This was the first time we negotiated with aliens face to face, and people couldn't help but be excited.

Even Zhang Yuan, the bystander, smelled the smell of gunpowder on the battlefield.

Until the afternoon of the fourth day, the scientists in charge of relevant science and technology were already a little unable to support themselves and were frantically injecting stimulants!

At this time, the first transaction was finally completed.

The two sides exchanged some knowledge of each other's generative knowledge of wisdom, brain perception science, and some bionics knowledge, and were quite satisfied with each other's gains...

Finally, Toss Civilization said: "The respected new human civilization is limited by the perceptual limitations of my civilization. The conventional interstellar cultural etiquette is not applicable to my civilization. I hope you can understand it."

"No problem, of course it's no problem! I hope that after this transaction, we both can gain something and establish a deep friendship."

The conventional interstellar civilization etiquette requires a camera to be turned on. At least it is necessary to create an image spokesperson for the entire civilization so that the other party can know the appearance of the opponent.

However, this Toss civilization has no eyes. Yes, they have no eyes and cannot see any pictures. They usually use ultrasound and magnetic field perception to replace traditional vision. This civilization does not even have related optical camera technology, so naturally there is no need to turn on the camera.

It is precisely because this interstellar civilization is so unique that humans have gained some knowledge of magnetic field perception in this transaction.

Of course, the more knowledge about intelligence, the better. Humans have only completed the first step of brain transformation. There is a second step and the third step...

Brain perception is a very important link at the intelligence level.

Red and green blind people cannot drive, and the learning speed of blind or deaf people is not as good as that of normal humans. The importance of perception is self-evident in the field of scientific research.

Some people have great auditory memory and some have great spatial thinking ability. In fact, overall, their outstanding talent in a certain aspect is that they are much stronger than ordinary people in the establishment of different perception systems.

But is human perception perfect? ​​Of course not. For example, humans cannot perceive real matter such as electromagnetic fields, so many people have difficulty understanding the power related to electromagnetic fields.

Ultrasonic waves, infrasonic waves, infrared, ultraviolet light, cannot be perceived by humans...

These weird papers on "magnetic field cognition" are incredible to humans and cannot be ignored by people because they involve real and true intellectual fields.

Since this is a private transaction, there is no way to ensure the correctness of this knowledge, after the transaction is completed, many researchers immediately began to distinguish the authenticity of the paper.

Of course, under normal circumstances, such small transactions do not require too much trouble, otherwise they will become famous in this trading market and will not be able to do anything.

"This member of the Toss civilization is indeed very strange!" One of the experts looked at these articles a few times and screamed with a hint of strangeness.

"The world they perceive is completely different from humans. What human eyes see are pictures, and what they see are some strange lines... Does the magnetic field perceive..."

"So, the direction of Toss civilization studying nature is very different from ours. They can directly feel the current, or in other words, the electric field and magnetic field generated by the current! It is very simple and easy for them to give birth to modern power technology, which is incredible!"

The world perceived by each intelligent creature is different. Generally speaking, the perception ability of organisms is mainly photons, sound waves, and thermal radiation.

But individuals of Toss civilization can actually feel the magnetic field!

Until now, people still have no way to understand what it feels like to "feel the magnetic field".

Zhang Yuan frowned and fantasized as much as possible about the feeling of magnetic lines around him, but he still couldn't imagine it in the end.

True perception is inevitably not comparable to some magnetic inductive lines, and the series of chain reactions brought about are even more difficult to predict.

He flashed his inspiration and suddenly said: "Pigeons can use the Earth's magnetic field to distinguish directions. Perhaps the pigeons have the basic ability to feel magnetic fields like this... But no one can describe what it feels like to distinguish magnetic fields."

"If humans can also feel the magnetic field, it will inevitably have a certain promoting effect on some cutting-edge scientific research. But how can we add another perception to the human brain?"

This is too difficult! No matter how smart you are, you cannot describe this feeling in words.

After a while of discussion, everyone shifted the topic to the Toss civilization's science and technology tree. This civilized electromagnetic industrial system is far stronger than the normal third-level civilization, but other technologies are not very good, especially optical technology, which has plummeted, not like a third-level civilization...

In physics, there is a saying: If a scientist habitually works with his neck tilted, that is, everything he sees has an angle of about 30 degrees with a normal person, and the whole world is tilted to him.

In his field of vision, the apple would fall to the ground at a slant of 60 degrees, and the way humans walked was also slanted, and everything was slanted.

So, will the physics researched by this scientist with a tilted neck be different from that of a normal person?

On the other hand, if a scientist studies natural phenomena in front of a mirror, will the physics in the mirror be the same as the physical laws of reality?

Similarly, it is like the perception of one kind of life, which is different from another life. What you see is a photon, but what I see is a magnetic field. So will the understanding of nature of both parties be different?

"At least from the current performance, the development of the technology tree will be very different, and the difficulty will be very different."

This is another big topic.

"Even, because the brain of the Toss civilization is different from other civilizations, the difficulty of self-improvement has increased a lot, which can be regarded as gains and losses."

After discussing it with such an interest, many scientific researchers couldn't stand the sleepiness and took a break from their busy schedule and went to bed.

After all, humans are not steel. After such a long time of negotiation, they are really overdrawn. They can't take stimulants anymore, otherwise something will have to happen.

One-third of the people are still on duty to check the new knowledge sent by the other party.

Zhang Yuan had just woken up from his dream and was thrillingly analyzing a patent drawing about the electromagnetic industry. He imported the data into a computer to analyze the feasibility of simulating these patents, and whether there is something worth learning from...

While simulation, I talked with my companions about the gains this time.

"This db-sdq grating is quite interesting. It can efficiently receive light quantums and distribute them."

“How about comparing our technology?”

"It's hard to say, we have to use it in practice to know that we can only use the computer for a while and know that it is indeed effective."
