Navigating curvature in the universe is a very boring thing, and it is even more boring than sailing with gravity near the strings of the universe...

The speed of gravitational navigation can reach about 10% of the speed of light, and at least you can enjoy the stars outside, which is enough to organize children to conduct cosmology education, but curvature navigation is completely impossible.

This leased war star has a speed of 10 times the speed of light!

In this case, the images observed by the naked eye are in chaos. All the stars in front are stacked together to form a huge light ball like the sun.

If you use a high-energy computer to carefully distinguish it, you will find that at least one trillion pictures are stacked together in this light ball!

So much so that people can't tell which light ray or which star emits it.

That is, external observations during curvature navigation have become a big difficulty. The faster the navigation speed, the more photons overlap. A special algorithm must be used to separate these overlapping pictures.

This kind of observation algorithm is something that must be studied by Level 4 civilization, otherwise it is equivalent to flying around with your eyes closed, and safety accidents are likely to occur.

After discovering this new phenomenon, humans and the Toss civilization began to study new topics with great interest. Anyway, they are idle, so it is good to study this aspect in advance.

If you observe it backwards, it will be pitch black. Whether it is electromagnetic waves or X-rays, there is nothing, and it is empty, it can be said to be the purest black in history!

Because there is no speed of matter to catch up with this planet, no matter what is observed behind, it is natural that nothing can be found.

In this case, the voyage of a hundred years seems extremely boring, except for occasionally cultural exchanges with the Toss civilization. This guy is the object of long-term contact in the future. Whether you like him or don’t like him, he is just there.

In short, this is the basic situation.

Since all preparations are ready, you must carefully observe the neutron star-neutron star system before you can formulate plans according to local conditions.

So, except for some astronomers and information experts studying the light mass superimposed by a large number of stars, inside the human fleet, hibernation-awakening-hibernation-awakening, these two links alternate with each other like the annual rings of trees.

A voyage of a hundred years is not too long. Most people can reach their final destination by just hibernating once or twice.

...

A hundred years passed by in a hurry.

In the last few days of the voyage, a team of human diplomats entered the Toss Civilized large mothership to discuss related cooperation matters. The external structure of the Toss Civilized mothership was nothing strange, like a super-large disc.

However, the various structures inside are as narrow as caves, which are somewhat similar to the pangolin underground city that people encountered in Glitze 581.

This is because the Toss is good at using ultrasonic perception and magnetic field perception, especially ultrasonic, which is suitable for playing a greater role in narrow spaces. If it is a wide place, this perception will undoubtedly be much blurred.

For this carefully selected partner, from people's current perspective, it is still quite reliable...

Compared with those third-level civilizations that are often hundreds of thousands of years old, the Tos civilization is a relatively young civilization. It only takes 40,000 years to enter the interstellar era.

In fact, for many level 3 civilizations, hundreds of thousands of years have been a long time, and the development of technology has long been almost stagnant. The longer it stays, the lower the probability of breakthrough... Therefore, a large number of interstellar civilizations are stuck in the interstellar trading market.

It cannot be said that they are completely depraved civilization, but the gap is not big from that step.

Only a relatively young and ambitious civilization would choose to spend a lot of effort to come to this strange star field and take such a bet.

In the interstellar trading market, Toss civilization is known for its old-fashionedness and dullness. When talking to them, it always makes it difficult to make real friends.

Of course, humans do not need any real friends. Civilizations that can fully integrate with each other are simply rare existences. As long as everyone can roughly cooperate, it is enough.

Instead of confronting each other in an all-round way, it is better to cooperate with each other. Anyway, there is an extra level 4 civilization in the universe, and humans will not lose a piece of meat and a more friendship. Why not do it?

With this thought, Zhang Yuan was invited to visit the Tusman's mothership in the diplomatic team.

"Ahem... the scenery inside your spaceship is very wonderful." Mr. Chen Mu said with a smile.

The lights inside the Toss mothership were not bright, the air humidity was very high, and the air pressure was slightly higher than what humans adapted to, but the oxygen concentration required by the Toss was only about 10%.

People gradually found out that if they get the other party’s approval, these large giant salamanders are quite interesting...

Every Toss has a tall four-clawed beast as its mount. This beast has eyes, furry and flexible arms, and seems to act as a soldier in the spacecraft.

In order to take care of these smart beasts, there is still a gentle light inside the Toss spacecraft.

"It is called Momero. After studying hard, intelligence can accomplish some simple tasks compared to our 10-12-year-old children. The most important thing is that it has eyes and is our companionship since ancient times."

"They also have their own simple language, and they are brought to the spaceship by us, and are an integral part of my civilization."

A large giant salamander is introducing his local culture to Zhang Yuan and others. This visual experience of "the giant salamander lying on the back of a hunting dog" is very interesting.

"Aowoo! Adasiva! Kajilak!"

Momero saw the group of humans wearing mechas, shouted loudly, and then stood upright as if saying hello.

When Zhang Yuan heard that there was a smart species with low intelligence inside the spacecraft, he was extremely surprised. Later, after hearing the other party tell the entire historical background, he gradually felt relieved and understood this culture.

In ancient times, the Toss lived in underground caves filled with magnetic fields. They evolved ultrasonic waves and magnetic field perception capabilities and were the overlords in the cave.

However, because the living space of the cave is too small and the food is sparse, it can accommodate not much population.

When the population increases, the Toss people will always walk out of the cave and come to the real ground.

The Toss without eyes were not very competitive on the bright ground, and on the spacious grassland, there were creatures that were more powerful than them.

According to the cruel law of survival competition for species, they either retreat to narrow caves and always become their own cavemen, or become extinct on the ground.

However, these Toss people were very lucky to meet a group of plant-eating creatures "Momero" with sloppy intelligence and gentle personality!

As a result, the two intelligent species gradually became companion existences, through the difficult ancient times, and developed into the interstellar era.

After the interstellar era, the beast "Momero" with a low intelligence level no longer has high utilization value. It can only be a guardian soldier or do some less complex handicrafts. The productivity of this handicrafts is almost negligible for interstellar civilization.

However, the Toss still did not abandon their former partners. Every newly born baby would choose his own companion partner to form a family and stay together for the rest of his life.

This is their unique culture...
