In the twinkling of an eye, three months passed like this. Zhang Yuan led six young men and women in the laboratory to the interstellar market for the second time in a small transport plane, accompanied by some interstellar soldiers and rotating human diplomats.

Their main rival this time is the tosian civilization, which is good at magnetic sensing. Humans are very interested in this strange race, not only its physiological structure, but also the history and culture of this civilization.

Of course, the history and culture of other people's homes are not so easy to obtain, and even human beings can not publicize their own culture and ideas without any reason. This is a very taboo behavior and affects their own safety.

Talking about this, Zhang Yuan solemnly said: "so, even if you are curious, don't talk about it. Our main purpose is to buy some magnetic induction organs, that is, biological organs of the tosian civilization. If you can buy more papers, it's also good. If we don't have a ready-made biological organ, it's still too difficult for us to fabricate one out of thin air. "

"But will they sell? I think it's very likely not. Even if you buy with amoeba points, the other party won't be willing to A boy with glasses said.

The cells in an organ must contain all the genetic materials of the tosian civilization. If human beings get these genetic materials, they can easily clone a tosian!

This is one of the biggest taboos in StarCraft etiquette.

Think about it, if other civilizations cloned human beings, and then used this clone to do biological experiments, dissected him. Even if this clone does not belong to the will of human beings, there will still be big waves within human civilization, and then there will be huge contradictions between the two sides, and even the outbreak of war is not impossible!

Or, a malicious civilization, aiming at human genes, has created a specific biological virus.

Therefore, within human civilization, it is strictly forbidden to sell any cell about itself, not even a hair.

This is also true in the theory of Toth civilization.

Zhang Yuan said with a smile: "so, it's very difficult to build mutual trust between civilizations. Even a cell is not willing to be exposed But we can't rule out that this kind of civilization doesn't matter to ethics. Let's do it anyway. "

"If we can't, we can only take the second place..."

Soon, reaching the inner ring trading area, the human spacecraft connected to the TOS communication signal.

As a result of several transactions, the relationship between the two sides is OK.

"Dear human civilization, what new ideas do you have?" This strange looking alien life said on the screen. It's the first time they've been on the screen.

He looks like a giant giant salamander. His limbs are longer than those of the giant salamander. He has six fingers and is very flexible. The only difference between the giant salamander and the giant salamander is that there are no eyes on his head. Instead, he has two protruding antennae.

In other words, the individual of this civilization can not feel any light, which may be because in ancient times, they lived in the dark cave and could not touch the light.

Because of this, the science and technology tree of TOS civilization is very different from the general interstellar civilization. Their technology products don't need screens that emit light, but devices that emit special magnetic fields.

The changes in the magnetic field make up the words and pictures of this civilization.

Their most commonly used tool is a strong magnet. When a strong magnet contacts other ferromagnetic materials, some materials will be magnetized and have magnetism. In this way, through magnetic induction, it can be easily identified to form pictures and words.

Of course, the TOS brain can sense the magnetic field, but it can't feel the higher frequency electromagnetic wave, let alone transmit electromagnetic wave, so they still speak, the sound frequency is very high, all of them are ultrasonic, this kind of ultrasonic is a kind of perception complementary.

For the human ear, it can't hear high frequency sound at all.

Therefore, they perceive the outside world through magnetic field, ultrasound, touch, smell and taste, which makes up for the lack of eyes to a certain extent. But only to a certain extent.

When the TOS learned about electromagnetic waves, they also longed for light.

These are the basic materials of civilization.

After Zhang Yuan explained his intention, the guy on the screen twisted his body, and a line appeared on the human screen: "I'm sorry, dear human, according to the internal security regulations, we can't sell our organs, even if you pay a lot of amoeba points, we still can't sell them."

"In fact, most interstellar civilizations with the same morality can't do that."

"Never mind, never mind, we can understand!" Zhang Yuanlian said: "we just want to get the scientific and technological information in this area, but if we don't have a ready-made organ, we really can't design it out of thin air..."

He soon put forward another plan: "if your civilization wants, we can apply for an open biological laboratory in the interstellar market to exchange sensory cells. The whole experiment is open to each other, and it is not allowed to measure the gene sequence. After the experiment is finished, all samples are destroyed, and no one is allowed to leave the field except the data. ""We are willing to provide 167 kinds of biological eyeballs, including human eyeballs, and share knowledge about bionic eyes. What do you think of this condition?"

Zhang Yuan added: "of course, we will pay for the points of the biological laboratory."

Just borrow a lab, at most 0.1 amoeba points.

After listening to Zhang Yuan's trading plan, the tosian on the opposite side of the screen thought for a long time, but didn't say a word.

As a rare species that can sense the magnetic field, it has a lot of communication with other interstellar civilizations

Similar experiments like Zhang Yuan's have been done, even more than 100 times!

However, more than 20000 years have passed.

They still don't see the real light. Other interstellar civilizations left with the TOS' magnetic field sensing data, but the TOS had no eyes, and a lot of experiments could not be done well, especially in biological experiments - it was impossible to put a little magnetic field on all organic matter.

It is very difficult to obtain the data only by ultrasonic wave and magnetic field.

This is too difficult, really too difficult, can't feel the light, just rely on the magnetic field, there are too many defects!

However, the Toth civilization is a civilization with strong self-esteem. It has a lot of tough scientists. It is impossible to develop from a difficult environment to the present without any excellent quality.

After a long time, communication came from the communicator, and scientists were willing to engage in such experiments because they got another chance

Free chance!

The tosian diplomat sighed, even though he knew that the experiment would probably be fruitless. However, even if it is one in ten thousand probability, we have to fight for it.

After this transaction was confirmed, the team led by Zhang Yuan couldn't help cheering up. It took 0.1 amoeba points to get the relevant information, which is too happy for human beings.
