These biological tissues are also the latest research progress. They are complex materials composed of organic substances such as DNA, protein and chitin. Although they can not compare with metal and nano materials in strength and toughness, they also have their own unique advantages.

First, the production speed is fast, the output is high, the repair is very simple, and even has some self-healing ability.

Second, it has a very strong and accurate information feedback ability!

Even though these biomaterials are not real organisms, they have stress similar to organisms. This kind of stress is like a human body. Where there is pain and acid swelling, you will get timely feedback. Moreover, its stable feedback ability is not possessed by conventional materials. This new type of biomaterial can be used not only in bionic robots, but also in various sensors inside spacecraft.

With the full power of Kunlun Mountain engine turned on, a large number of data reports appeared on the screen in such a short time, "the temperature of d1334 energy room exceeds the standard, it is suspected that the output power is insufficient, and the reason is to be determined..."

"Report to the captain that there may be metal fatigue in m112 area..."

"The observation room in J5 direction has a fault, the reason is unknown, and it needs to be investigated."

The tracking reports were summarized to the captain's room one by one. Zhang Yuan looked at them carefully for a while, but they were all small problems. There were no so-called orange warnings and red warnings, so he didn't have to issue emergency orders in person.

At 60000 kilometers ahead, there is a space fleet composed of 26 medium-sized frigates and a large destroyer!

The tonnage of each frigate is about 6000 tons and the length is about 240 meters, just like the size of an aircraft carrier.

The model of this frigate is called "Haiyan space-iii", which uses a large number of nanocomposites, so it is so lightweight.

Its volume is not small, but it is like a chicken compared with Kunlun mountain.

Each "petrel" can carry 40 small UAVs, 26 large interstellar missiles, 6 small electromagnetic guns and a varying number of small interception lasers. It can effectively attack targets within 1 million kilometers, and its mobility is much stronger than that of Kunlun mountain.

This is already a real Starfleet!

Zhang Yuan glanced at the screen. The distance between the formations in front was well controlled. There was no sign of the spacecraft detaching for the time being.

On the other screen, a series of data are displayed. The military forces in front are accelerating continuously, with an acceleration of 5 meters and no quadratic second.

The current acceleration of "Kunlun Mountain" is three thousandths of a meter per second.

Compared with such a large spacecraft, this acceleration is quite good.

Space navigation itself is moving forward at a snail's speed, which we have long been prepared for. Therefore, after reading this series of parameters, Zhang Yuan also sat in his seat easily.

"In this way, there should be no big problem. After some maintenance, we can start a real deep space voyage."

"Originally I wanted to launch colonial ships, but I didn't expect that we were this group of new explorers."

"I think that in these five years, we can build one or two 'Falcon-II' spacecraft to enhance military capability."

"This should be no problem."

"Falcon" destroyer, of course, is an upgraded version of petrel. It has larger tonnage and stronger attack ability. At present, mankind has only built one.

Looking at the magnificent scenes in front of us, Zhang Yuan and Li Zhendong were also filled with emotion and kept discussing what needs to be developed in the last five years.

The whole new civilization will be divided into two in this voyage. One group will stay on this planet, and the other will go to the distant starry sky! Of course, they left with the Kunlun Mountains.

In the survey two years ago, about 8 million people were willing to follow the "Kunlun Mountain" to leave this starry sky, go to the next possible life planet, discover unknown civilizations and contact the wider world. This population exceeded expectations. In fact, it is the spiritual heritage brought by the Gliese leaving on the earth times.

The remaining six million people want to stay on this planet and continue to develop.

There is nothing to say about this choice. Everyone has his own aspirations. It is not necessary for all the population to move towards the stars. It is also good to retain some civilized kindling here.

Even if this behavior will greatly weaken the comprehensive strength of the whole civilization, this weakening actually has little to do with it. With the passage of time, adjusting the birth rate can easily make up for it.

On the one hand, with this interstellar army, mankind has enough self-protection ability. If you encounter a fairly strong civilization, can't you escape after fighting?

On the other hand, according to the information sent by the golden sun, human beings do have a high probability of developing to their own upper bound. With their own creative ability, it is difficult to excavate a new science and technology tree.

There are fewer and fewer big fish in physics, and other disciplines have fallen into bottlenecks or thinking patterns.

For example, for some biological materials used in universal factories, it is impossible for humans to think of this branch of science and technology until death.

These biomaterials are neither real organisms nor pure rigid materials. Anyway, they are the combination of proteins, DNA and other organic substances, and they are also stressful. It's not difficult to understand after having a physical object, but human beings still don't know how it was created.

Another example is biochip, which is not unexpected, but directly ignores its potential, or abandoned for various reasons.

In addition, after more than 100 years of development, the new civilization has basically cleaned up the heritage of earth civilization. "Kunlun Mountain", "petrel" and "Falcon" are almost the limit of current science and technology. Although there may be room for optimization, it is unlikely that a real qualitative change in performance will occur.

Therefore, people are determined to set sail as soon as possible. There is no need to develop here all the time.

"I didn't expect to have the second deep space voyage in my lifetime."

Looking at the starry sky outside, suddenly, everyone in the room was full of pride!

"That's right." Zhang Yuan suddenly remembered one thing, "seven months later, we can sail to the position of the d99834j cosmic string."

"It's the first time for a spaceship to accelerate with a cosmic string. Do you have any details to add? I don't want the Kunlun mountain just built to fall apart by the huge gravity... "

"No, no, Captain, you must believe in our scientific and technological strength. Kunlun mountain can never fall apart!"

Everyone laughed.

It has to start seven years ago
