It has been more than 800 years since she left the solar system, and Xue Feng, who has recovered from her state, began to study human science and technology with full enthusiasm.

At least now, Yukikaze is not the only one who can see the scenery outside with the help of Behemoth's eyes, and the huge biosimulating panoramic window allows the scenery in the universe to be displayed in the central chamber for others to see.

Other technological breakthroughs, among which are quantum communication technology, the fusion of this technology has made the connection between the snow wind and the insect swarm reach the point of almost zero delay, who said that the spiritual connection cannot use quantum entanglement state technology?

Isn't it all implemented in the snow wind!

The utilization rate of nuclear fusion has been higher, to 80%, and the solar furnace can be made smaller, at least for now, the hosts of the entire swarm have also given up chemical energy propulsion and switched to new fusion technology.

There is no need to worry about this anymore, the hosts will no longer be able to increase to their current speed of 1,300 kilometers per second.

However, none of the above is the most important evolution of the swarm, the only one that can be called a cross-era evolution, only the transformation of Eva's biological brain perfectly matches the quantum computing method of human beings, and the backward ordinary brain methods in the past have been abandoned, and the calculation and management of the swarm data have been more than doubled.

As long as you give a question, you can give an answer immediately, the ordinary computer of human beings has to calculate the problem of 1.5 billion years, Eva can now give the answer in a second, this is no longer a biological brain, and even backward electronic computers can compare to the technology, so Xuefeng named Eva's brain quantum brain.

Eva, who has no basic body, is doing calculations every day, or assisting Xuefeng in research, which is more than twice as efficient for swarm management.

If this doesn't form a concept, let's compare the time it took for the swarm to line up for half a minute, which is still the result of unified instructions, and it is up to the swarm to judge their position.

Now this time has been shortened to five seconds, even if hundreds of thousands of swarms have to line up, it will not be much faster than five seconds, not excluding the slow action unit, at most it will only be completed in ten seconds, because when issuing instructions, the position of the arrangement and the path of arrival are calculated seamlessly.

It ensures that there will be no time delay between individuals because of simple collisions.

The research of this quantum brain alone took Xue Feng a full five hundred years, more than twice the time required by other technologies.

But the effect is also significant, at least Yukikaze is very satisfied with Eva's improvement.

Unfortunately, the solar furnace was miniaturized and stuffed into each swarm unit.

This technology, even if Eva tried her best, couldn't calculate it, it seemed that there was a lack of technical links in some fields, and it was impossible to break through in the short term, so Xuefeng had to give up.

Scientific research is like that, and speed is not enough.

Sometimes a little inspiration can become an opportunity for a technological breakthrough, and in human terms, it is a chance, and it is not urgent at all.

As for the snow wind that has been bothering him, how to make the supply of the swarm more efficient, he has no clue. Let her feel that if she continues to think about it, she will become bald.

She can't just put a charger on every bug and charge it like an electric car!

That scene is very strange when you think about the snow wind, and it is not elegant at all.

So she developed wireless charging technology, but it has not been able to be implemented because there is no organ in the insect colony that can receive and send energy.

If the human beings who have not been able to leave the planet belong to the first-level civilization, then the swarm that has mastered the nuclear fusion technology and can sail to the outer galaxy has undoubtedly risen to the level of the second-level civilization.

As for what a third-level civilization looks like, Xuefeng preliminarily estimates that it should be a third-level civilization that has mastered the controllable energy armor and is not afraid of any celestial threat in the universe.

As for this energy armor, Xue Feng is just thinking about it now, even if the people of the earth know that the energy armor is a way to bind high-energy particles to the surface with a strong magnetic field to form a solid shield, it is too difficult to do this.

Xue Feng doesn't even have an energy weapon now, and the physical function of the insect swarm is not enough to support the application of energy weapons.

The Fire Spider, which uses a method similar to an electromagnetic cannon to fire liquefied particle shells, can only be regarded as a quasi-energy weapon, and there is still a long way to go before it is a real energy weapon.

And so, after stumbling on the technical level, more than 1,500 years passed on the journey of the swarm.

Looking at the Sun from its present perspective is the same as looking at any other star, without any difference.

This shows that the insect swarm has already traveled nearly half of the way, which is why the sun's rays have become so faint.

But this is also a good thing, which means that the snow wind is closer to Tianyuan Si.

"Mother, the direction of progress, high-energy particles, radiation fluctuations, forced through, unknown factors, is there a detour?"

Energetic particles, in other words, are dense energy substances.

In human parlance, a huge nebula appeared in front of the swarm, the gaseous nebula is not a fun thing, and the powerful energy contained in it is a dangerous and uncontrollable environment for the swarm without an energy shield.

Otherwise, where the swarm can pass through safely, Eva will not warn Yukikaze.

The panoramic window shows that there is a dark red cloud in front of it, and there is even a large area of strange light in the red nebula that stretches for more than ten light years, which is the energy reaction phenomenon after the dust and matter gather.

Each nebula is a precursor to a star, and it is possible that in the future, due to their gravitational relationship, they will eventually come together to form new star systems.

The residue left behind after the formation of the star will become a planet revolving around the star, but it is not good news for the current swarm.

"You don't need to turn around, just pass it over."

The materials required to turn are no less than accelerating again, and there is even the danger of deviating from course, although the danger of passing through directly is not small, but it will not lose the direction of progress.

For the vast universe, once you get lost and can't find the right direction, you are likely to drift in the universe forever, and the stars that are close in front of you can make you run and break your legs, and even when the supplies are exhausted, you may not be able to reach the new galaxy, which is a huge gamble.

Xue Feng couldn't take the future of the entire swarm as a child's play, so she made the safest decision.

Even if more supplies are consumed, they must not deviate from the course.

So the swarm broke in, and in the strange-looking red nebula, the surrounding sky was dyed red.

It was the result of the light being obscured and scattered by the dust, and the speed of the swarm began to slowly decrease in the dust that formed the nebula, and the dust became a resistance to the progress of the swarm, forcing the snow wind to accelerate the swarm every once in a while to maintain the same speed, trying to quickly pass through the nebula.
