These biological tissues are also the latest research progress, it is a complex material composed of organic matter such as DNA, protein and chitin, although it is not comparable to metal and nanomaterial in terms of strength and toughness, but it also has its own unique advantages.

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

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

Even though these biomaterials are not real living organisms, they have a similar level of stress to living organisms. This kind of stress is like a human body, where there is pain, where there is soreness, it will get timely feedback. Moreover, its stable feedback capability is not available in conventional materials. Whether it is biomimicry robots or various sensors inside the spacecraft, this new type of biomaterial can be used.

With the full power of the Kunlun Mountain engine turned on, in just a while, a large number of data reports appeared on the screen, "The temperature of the energy room D1334 exceeds the standard, and the output power is suspected to be insufficient, the reason is to be determined......"

"Report to Captain, possible metal fatigue in the M112 area......"

"The observation room in the J5 direction is malfunctioning, the cause is unknown, and it needs to be investigated."

The tracking reports were summarized in the captain's room, and Zhang Yuan looked at them carefully for a while, but they were all just minor problems, and there were no so-called orange warnings and red warnings, so he didn't bother to give emergency orders in person.

And 60,000 kilometers ahead, there is a space fleet consisting of 26 medium-sized frigates and a large destroyer!

Each frigate has a tonnage of about 6,000 tons and a length of about 240 meters, just the size of an aircraft carrier in the past.

The frigate is called "Haiyan SPACE-III" and uses a large number of nanocomposite materials, which is why it is so lightweight.

Its size is not small, but compared to Kunlun Mountain, it is like a little chicken.

Each "Haiyan" can carry 40 small unmanned aerial vehicles, 26 large interstellar missiles, 6 small electromagnetic cannons and a varying number of small interceptor lasers, which can effectively hit targets within 1 million kilometers, and its mobility is much more powerful 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, and there was no sign of the spacecraft being disorganized for the time being.

On the other screen, a series of data is displayed, and the military troops in front are constantly accelerating, with an acceleration of 5 meters less than a square second.

The current acceleration of "Kunlun Mountain" is 3/1000 meters per square second.

Compared to the size of such a large spaceship, this acceleration is already quite good.

Space navigation itself is a snail-like speed of progress, which everyone has long been mentally prepared for, so after reading this series of parameters, Zhang Yuan can be regarded as sitting in his seat easily.

"Looking at it this way, there shouldn't be much of a problem, and after some overhaul, we will be able to start a real deep space voyage."

"Originally, I wanted to launch a colony ship, but I didn't expect that we would be this new group of explorers."

"I think that in the next five years, one or two 'Eagle Falcon-II' spacecraft can be built to enhance military capabilities."

"This should be fine."

The destroyer "Eagle Falcon", of course, is an upgraded version of the Petrel, with a larger tonnage and stronger attack capabilities, and only one has been built by humans at the moment.

Looking at the magnificent scenes in front of them, Zhang Yuan and Li Zhendong were also full of emotion, constantly discussing what needs to be developed in the last five years.

The entire new civilization will be split in two in this voyage, one group will stay on this planet, and the other will go to the distant starry sky! Of course, this group of them left with Kunlun Mountain.

In a survey two years ago, about 8 million people were willing to follow the "Kunlun Mountain" to leave this starry sky and go to the next planet of possible life, discover unknown civilizations, and get in touch with the wider world. This population is more than expected, and it is actually the spiritual legacy of the Gliese people who left on the Earth Age.

There are still six million people left who want to stay on this planet and continue to develop.

There is nothing to say about this choice, everyone has their own aspirations, there is no need for the entire population to go to the stars, and it is also good to keep some civilization fire here.

Even if this kind of behavior will greatly weaken the overall strength of the entire civilization, this weakening is actually not very important, and with the passage of time, it is easy to make up for it by adjusting the birth rate of the population.

On the one hand, with this interstellar army, humanity has enough self-preservation. If you encounter a fairly powerful civilization, can't you run away if you can't defeat it?

On the other hand, according to the information sent by the Golden Sun, there is indeed a high probability that human beings have developed to their own upper realm, and with their own creative ability, it is already difficult to dig out a new technology tree.

There are fewer and fewer big fish in physics that can be caught, and other disciplines have fallen into bottlenecks or mindsets.

For example, some of the biological materials used in the universal factory are unlikely to be considered by humans until they die.

These biological materials are neither real organisms nor pure rigid materials, but are a combination of various organic substances such as proteins and DNA, and have a certain degree of stress. It is not difficult to understand the physical object, but human beings still do not know how it was created.

Another example is biochips, which are not unexpected, but directly ignore their potential, or are discarded for various reasons.

In addition, after more than 100 years of development, the new civilization has basically eaten the heritage of the earth's civilization, "Kunlun Mountain", "Haiyan" and "Eagle Falcon", which are almost the limit of current science and technology. While there may be room for optimization, a real qualitative change in performance is unlikely.

Therefore, people decided to set sail as soon as possible, and there was no need to continue to develop here.

"I didn't expect to be able to make a second deep space voyage in my lifetime."

Looking at the starry sky outside, all of a sudden, everyone in the room was full of pride!

"That's right." Zhang Yuan suddenly remembered something, "Seven months later, we will be able to sail to the position of the D99834J Cosmic String. ”

"It's the first time that a spacecraft has been used to accelerate a spacecraft. Do you have any more details to add? I don't want the newly built Kunlun Mountain to be broken up by the huge gravitational pull......"

"No, no, Your Excellency, you must believe in our scientific and technological strength, Kunlun Mountain will definitely not fall apart!"

Everyone burst out laughing.

It all started seven years ago......
