Curvature navigation is a very boring thing to do in the universe, and even more boring than navigating with gravity near the cosmic strings......

Gravitational navigation can reach about 10% of the speed of light, and at least you can admire the stars outside, which is enough to organize children to educate about cosmology, but curvature navigation is completely impossible.

This loaned star is 10 times the speed of light!

In this case, the image observed by the naked eye is disorganized. All the stars in front of them were stacked together, forming a huge cluster of light like the sun.

If you use a high-energy computer to distinguish carefully, you will find that there are at least 100 trillion pictures stacked together in this light cluster!

So much so that people are completely unable to tell which light is emitted by which star.

In other words, the external observation of the curvature becomes a great difficulty, and the faster the voyage, the more photons overlap. A special algorithm is required to separate these overlapping images.

This kind of observation algorithm is a must be studied by the fourth-level civilization, otherwise it is equivalent to flying around with your eyes closed, and it is easy to have safety accidents.

After the discovery of this new phenomenon, mankind and the Toth civilization began to study new topics with great interest. Anyway, being idle is idle, and it's not bad to research this aspect in advance.

If you look at the rear, it is pitch black, whether it is electromagnetic waves, X-rays, nothing, empty, it can be said to be the purest pitch black in history!

Since no matter has the speed to catch up with this planet, all the observations from behind will naturally not be able to see anything.

In this case, the hundred-year voyage seemed boring - except for the occasional cultural exchange with the Toth civilization. This guy is the one you need to deal with for a long time in the future, whether you like him or not, he is here and there.

All in all, that's pretty much the basics.

Since all the preparations are in place, and the neutron-neutron star system is properly observed, the plan can be made according to the local conditions.

Therefore, in addition to some astronomers and information experts studying the light cluster that is superimposed by a large number of stars, inside the human fleet, hibernation-awakening-hibernation-awakening, these two links are like the rings of trees.

A hundred years is not too long, and most people only need to hibernate once or twice to reach their final destination.

……

A hundred years passed in a hurry.

In the final days of the voyage, a team of human diplomats entered the large mothership of the Toth civilization to discuss cooperation. The exterior structure of the mothership of the Torth civilization is nothing unusual, like a super-large disk.

However, the structures inside are quite narrow like caves, similar to the pangolin underground city that one first encountered in Gliese 581.

This is because the Tothians are good at using ultrasonic sensing as well as magnetic field sensing, especially ultrasonic is suitable for playing a greater role in confined spaces. If it is a wide place, this perception will undoubtedly be much more blurred.

For this carefully selected partner, from the perspective of people, it is quite reliable......

Compared with those third-level civilizations that are hundreds of thousands of years old, the Torth civilization is a relatively young civilization, and the time it has entered the interstellar age is only 40,000 years.

In fact, for many third-level civilizations, hundreds of thousands of years is already a long time, and the development of science and technology has long been almost stagnant, and the longer it stays, the lower the probability of breakthrough...... That's why a large number of interstellar civilizations are stranded in the interstellar trading market.

It cannot be said that they are a complete civilization of the sunkers, but they are not far from that step.

Only a relatively young and energetic civilization with a high level of motivation would choose to spend a lot of effort to come to this unfamiliar star field to make such a gamble.

The Torth civilization is known for being old-fashioned and sluggish in the interstellar market, and when talking to them, they always have a tone that is not approachable, so that it is difficult to make real friends.

Of course, human beings don't need any real friends, and civilizations that can fully integrate with each other are simply rare, as long as everyone can roughly cooperate.

Instead of all-out confrontation, it is better to cooperate with each other, anyway, there is one more fourth-level civilization in the universe, and human beings will not have one less piece of meat, and there will be one more friendship, why not?

With this in mind, Zhang Yuan was in the diplomatic team and was invited to visit the mothership of the Toths.

"Ahem...... The scenery inside your spaceship is amazing. Mr. Chen Mu said with a smile.

The lights inside the Tothian mothership are not bright, the air humidity is very high, and the air pressure is slightly higher than the humans are used to, but the oxygen concentration required by the Tothians is only about 10%.

In the gradual contact, people found that if they were approved by the other party, these large baby fish were still quite interesting......

Each Toth has a tall four-clawed beast as a mount, this beast has eyes, hair, and flexible arms, and seems to act as a soldier in the ship.

In order to take care of these intelligent beasts, the Tothians still have a soft light inside the ship.

"It's called Momero, and after studying hard, it has the intelligence to be able to do some simple tasks relative to our 10-12 year olds, and most importantly, it has eyes, and it is our companion since time immemorial."

"They also have their own simple language, which we brought to the spaceship and are an integral part of our civilization."

A large baby fish is introducing its local culture to Zhang Yuan and others, and this visual experience of "baby fish lying on the back of a hunting dog" is very interesting.

"Woohoo! Adashiva! Kamojirak! ”

Seeing the mecha-clad humans, Momero shouted loudly, then stood upright, as if to say hello.

Zhang Yuan was extremely surprised when he heard that there was an intelligent species with a low level of intelligence inside the spaceship, and it was only later, after listening to the other party tell the entire historical background, he gradually relieved and understood this culture.

In ancient times, the Tothians lived in underground caves filled with magnetic fields, and they evolved ultrasonic and magnetic field perception abilities, and were the overlords of the caves.

However, due to the fact that the living space of the cave is too small and food is scarce, it can accommodate not many people.

As the population grows, the Toths will eventually come out of the cave and onto the real surface.

The Toths, who have no eyes, are not very competitive in the ground full of light, and in the spacious grasslands, there are creatures that are more powerful than them.

According to the brutal laws of survival competition of the species, they either retreat to their narrow caves and become their own cavemen forever, or they become extinct on the surface.

However, these Tothians were lucky enough to encounter a group of herbivorous creatures "Momero", who were intellectually so-so and had a relatively gentle personality!

As a result, the two intelligent species slowly became companions, survived the difficult ancient era, and developed into the interstellar era.

After arriving in the interstellar age, the beast "Momero", which has a low level of intelligence, no longer has too high use value, and can only be used as a guard soldier or do some less complicated handicrafts. The productivity of this handicraft is almost negligible for an interstellar civilization.

However, the Tothians still did not abandon their former partners, and each newborn baby would choose their own companions to form a family and stay together for the rest of their lives.

This is their unique culture......

Zhang Yuan stretched out his hand to tease the fluffy guy, Momero is somewhat similar to a combination of a large wolfdog and an orangutan, they are vegetarians and do not have a high need for food, but they are stronger and smarter than wolfdogs.
