After ending the matter of the Heaven Breaking Sword Sect, the first thing Wei Qingyang did was to relay the thruster formation.

The so-called not breaking or standing, in the previous acceleration process, Wei Qingyang has found some shortcomings of the propeller formation group laid, such as the layout is not reasonable enough, and the resources are not used to the maximum.

It's not easy to make adjustments, as it will affect the overall layout and you will have to tear it all over again, which is very troublesome. However, now that the previous formation has been destroyed, and now that it has to be re-laid, there are naturally no more scruples.

Not only that, Wei Qingyang has also tested several more efficient thruster formations during this time, and now there is a heavenly treasure from Lingyun Peak to supplement, and it is even more handy to lay.

In particular, the asteroid – now named Qingyang Star by Wei Qingyang – has now been transformed from an irregular shape into a sphere by him. This means that Wei Qingyang has more room to play.

This time, it only took about half a year for the thruster formation group to be laid. Not only that, but compared to the previous ones, the current formation group has greater thrust and higher efficiency.

Overall, its propulsion has been more than tripled compared to before, from 1.5 millimeters per square second to 5 millimeters per square second, and the consumption of star power has been reduced by about 30 percent.

The increase in acceleration means that the time to accelerate to 3,000 kilometers per second will be shortened from more than 60 years to less than 20 years now. At the same time, the total voyage time has changed from more than 450 years to about 400 years.

Although the time shortened may not seem much, it is mainly due to the influence of the interstellar wind.

There is a gang wind in the interstellar space, and the faster it moves, the deeper the erosion of the interstellar gang wind, which is a basic common sense in the cultivation world. However, in Wei Qingyang's view, this should be an interstellar dust particle impact and interstellar radiation.

Because of the existence of the interstellar wind, the speed of Qingyang Star must be stopped after accelerating to 3,000 kilometers per second. Otherwise, the impact of interstellar winds will not be negligible.

However, this is not immutable.

Wei Qingyang already has plans to improve the resistance of Qingyang Star and the Sky Breaking Sword Array to the interstellar Gangfeng, once it is improved, its speed will be faster, and the time to reach the South Gate Two Galaxy will be shortened again.

After the formation was laid, Wei Qingyang immediately began to transform the Sky-Breaking Sword Formation.

This Sky-Breaking Sword Formation, with a trace of sword intent left over from the Sky-Breaking Sword as the eye of the formation, its power is really not small, even now, recalling his previous experience, Wei Qingyang is a little afraid.

If I hadn't made an atomic bomb and blown it up, I'm afraid I'd be dead by now.

This sounded the alarm for Wei Qingyang.

This universe seems to be nothing, it seems to be peaceful, but God knows where danger awaits you. Improving the power of self-preservation as much as possible is the only way to save your life.

The original Heaven Breaking Sword Array has been repaired and added by dozens of generations of Heaven Breaking Sword Sect after thousands of years, and its power is great, but it is extremely complicated.

It contains millions of small formations of different types and different functions, and the interaction between small formations may affect the overall situation if you modify a small formation. Fortunately, Wei Qingyang has been promoted to the realm of "unknowable", and he can use thousands of things with one heart to sort it out in more than a month.

The next step is to make adjustments. Wei Qingyang drastically cut down nearly ten percent of the small formations, dispersed and integrated their functions into other small formations, and comprehensively adjusted the structure to sort out the path for the flow of star power.

It's a huge undertaking. Even with Wei Qingyang's cultivation and doing it with all his might, it took a few months to adjust.

After the modification and adjustment, the consumption of the power of the stars has been reduced by 13.2%, but the overall performance has been increased by nearly 20%, whether it is stealth, defense, attack, or detection, it has been greatly improved compared to before.

The most important improvement is that in the event of an emergency, the current Sky-Breaking Sword Array can expand its coverage to the entire Qingyang Star, and include the entire Qingyang Star in its own protection range.

Of course, this will consume more star power. But it doesn't matter, in normal times, its enveloping range is still only one Qingyang Peak, and it can even be smaller, without expanding to that big.

At this moment, this Heaven-Breaking Sword Array has become Wei Qingyang's greatest reliance for self-preservation in this vast universe.

In addition, Wei Qingyang also built more than 30 space telescopes to monitor any movement in the surrounding star fields at all times, and constantly look for traces of macroscopic stars.

When everything was done, the speed of Qingyang Star also increased to 160 kilometers per second, and the total range also traveled 57 billion kilometers.

The increase in speed should be done slowly, and this must not be rushed. On this small Qingyang Star, apart from cultivation, Wei Qingyang really had nothing else to do.

But now that he is in the realm of "unknowable", how to develop in the future is simply a black eye, except for repeatedly polishing the quality of Yufu and doing water grinding work, I don't know what else can be done.

After thinking about it for a while, Wei Qingyang finally decided that it was better to devote time and energy to the development of science and technology.

In his previous life, Wei Qingyang was an astronomer and astrophysicist, who was proficient in optics, astrophysics, cosmology, telescope engineering, mathematics and other disciplines, and had high attainments, as well as programming, computer principles, algorithms, etc., but he was not deep enough to meet the needs of his work. In addition, for other disciplines, it can only barely exceed the level of ordinary people's cognition.

Even if he can use thousands of dollars now, it is impossible to promote the development of science and technology by himself. It is impossible to restore the existing level of science and technology in the previous life.

"Little by little."

Wei Qingyang sighed secretly.

This kind of thing, without a trustworthy person, he can't fake the hands of others. Anyway, now there is enough time, Lingyun Peak-now renamed Qingyang Peak by Wei Qingyang--all kinds of materials and minerals are sufficient, and there is a bonus of cultivation, a person can use thousands of people in his life, and the efficiency is higher, the coordination is better, and it is not without hope of success.

Even if the cultivation is higher in the future, the ability to distract and split the gods is stronger, and when you can use tens of thousands, hundreds of thousands, or millions of people with one mind, it is not impossible to rely on your own ability to reproduce the scientific system of human beings in the previous life, and even promote the development of science and technology with your own strength.

So Wei Qingyang started from a small place, first tried to do some mechanical research and pondering in the steam age, which can be regarded as a comprehensive self-study of mechanical structure, mechanical principles, materials science, engineering, etc.

There were fewer disciplines in the steam age, and with Wei Qingyang's ability at the moment, it was still possible for one person to master the knowledge of all the disciplines involved.

Even so, it took Wei Qingyang seven or eight years to figure everything out.

I don't know if I don't study it, but when I really study it, I know that this thing seems simple and stupid, but it is also very high-tech. The selection of materials, the shape of parts, force analysis, overall layout, structure, etc., are all asked.

Wei Qingyang has a deep understanding of why there should be enough population base to promote the development of science and technology. It's very simple, this thing, if there are fewer people, you can't even learn it, so how can it develop.

It can only be done if multiple people work together, each person is proficient in a part, and a part is studied in depth.

Fortunately, Wei Qingyang can use thousands of people by one person, so he can do this with the strength of one person.

At this time, the speed of Qingyang Star has increased to more than 1,300 kilometers per second, and it is nearly 200 billion kilometers away from the sun, about 0.02 light years.

At this moment, Wei Qingyang was buried in a large pile of debris, pondering how to refine special steel with performance that meets the indicators, and when he was scratching his head, suddenly, Wei Qingyang looked stunned and instantly became serious.

He threw down the work in his hand, and his body flew up quickly, and in an instant, he flew outside the Heaven Breaking Sword Array.

In this vast and empty space, under the starry sky, Wei Qingyang faced the direction of the sun and refused to stagger his eyes for a long time.

The sun should be there.

During this time, although he was busy doing research and reproducing the scientific system of his previous life, there were always some thoughts scattered and controlling those telescopes to observe the surrounding environment.

One of the telescopes is facing the direction of the sun.

Before, the sun had been visible, but just now, the sun suddenly disappeared.

Even at such a distance, with the brightness of the sun, it is very bright and dazzling, even without the help of a space telescope, with the naked eye, it is the brightest star of the whole day, and it can be seen very easily.

But as if something suddenly blocked between Qingyang Star and the sun, Wei Qingyang couldn't see it anymore.

The coordinate data calculated from the distance and angle between different stars clearly and unmistakably told Wei Qingyang that the sun was there, and it would not be wrong.

But he couldn't see it, he couldn't see it anyway.

Something must have happened.

"Could it be...... The sun had disappeared eight days ago, and had been destroyed by the 'monster', or the rest of the being, but I had just discovered it now? ”

At this moment, the distance between Qingyang Star and the Sun is nearly 200 billion kilometers, and the sun's light travels at the speed of light, and it takes nearly eight days to travel from the Sun to Qingyang Star.

This made Wei Qingyang's heart heavier and heavier.

"No, it's not right, it's not right."

Wei Qingyang muttered, his eyes continued to stare at the place where the sun was originally located, staring at the empty space there, and refused to look away.
