Absorbing all the power of the stars gathered by this asteroid before, Wei Qingyang's reserves quickly climbed from less than half to two percent. The next step is the water mill kung fu, and you have to wait for it to converge little by little, so that you can absorb it little by little.

It was too slow, but Wei Qingyang didn't have any way.

Some so-called formations that can gather the power of the stars and the like are actually for the inside of the stars. For example, on the earth, some places have strong star power, which is suitable for cultivation, and is suitable for the breeding and reproduction of heavenly and earthly treasures, and some places are barren and not suitable for cultivation, and some formations can allow a certain place to absorb the star power of other places, making its star power more abundant, so as to form a cave heaven and blessed land, etc., which are all internal redistribution of the earth's star power.

The total amount of star power absorbed and contained by the Earth will not change. More here, less there.

Up to now, this asteroid is so big in total, Wei Qingyang has absorbed the entire planet at once, and where is it still needed, where is there more star power and where is less.

In addition to the slow convergence of star power, there is another thing that worries Wei Qingyang.

It's still the aftermath of the "that blow" of the monster that came from nowhere.

Even if it is tens of billions of kilometers away from the sun, it cannot escape its sphere of influence. Staying here for a long time is still a death, and the difference is only that you die a little faster and die a little slower compared to the interior of the solar system.

What's more, at the moment the asteroid is slowly approaching the sun, not moving away.

This made Wei Qingyang's heart even more worried.

In addition to this, there is one more thing.

"With the speed at which this asteroid's star power is converging, it will take at least a month for me to regain its full strength. So, what about a month later? ”

In his heyday, Wei Qingyang launched Starlight Escape, which could support a flight time of about five months, and could fly a distance of less than 40 billion kilometers.

And after that? Looking for another asteroid to recuperate?

It's not realistic.

The solar system from the inside to the outside is Mercury, Venus, Earth, Mars, the asteroid belt, Jupiter, Saturn, Uranus, and Neptune. Beyond Neptune are overseas celestial bodies, from the inside to the outside, the Kuiper belt, the ecliptic discrete disk, the Shills cloud, and the Oort cloud.

In general, the further out you go, the emptier the universe, the more difficult it is to find macroscopic objects.

At this moment, Wei Qingyang's position is probably between the ecliptic discrete disk and the Hillss cloud. Now the asteroid does not belong to either the ecliptic discrete disk or the Hills cloud, it is a separate celestial body.

At this stage, it has already taken so much effort to find it, and beyond that, God knows if it will be able to find a place to stay.

If you can't find a place to stay, even if you are as strong as Wei Qingyang, you can only die when your star power is exhausted in the end.

There is another possibility, that is, to stay here for a long time, and after recovering its heyday, continue to wait for the star power to gather, refine the excess star power into "spirit stones", and carry it on the body for replenishment.

The spirit stone is a conglomeration of the power of the stars, which allows the monk to integrate into the body without any hindrance without concentrating or cultivating. In the solar system, spirit stones, especially high-quality spirit stones, are hard currency. Whether it is traveling at home or killing people to seize treasures, or arranging formations, refining magic weapons, and pills, they are all indispensable.

But under the influence of "that blow", at this distance, Wei Qingyang can live for a few more years at most, and the spirit stones refined from the star power gathered in a few years will be gone after a few times at most.

This road is still not going to work.

Finding this asteroid is only a solution to the urgent need, and in the long run, it is still a dead end.

Sitting casually in a "canyon", Wei Qingyang fell into deep thought again.

"Walking is death, staying here is death, is there really no way?"

After thinking for a long time and gaining nothing, Wei Qingyang casually absorbed the power of the stars gathered by this asteroid during this time, and sighed.

"Strolling" on this asteroid, looking up at the starry sky, Wei Qingyang muttered: "If only this asteroid could follow me." ”

Think about it, if Wei Qingyang can take it with him, he can be replenished by the power of the stars along the way, and he doesn't have to worry about dying from the depletion of the star power, even if the speed is a little slower, he is willing to accept it.

But reason told him that it was impossible.

Building a foundation, turning clouds, pouring the sea, and the four realms of Dongxuan, when you reach the realm of pouring the sea, you already have the ability to turn over the river and the sea, and it is easy to level a mountain, not to mention Wei Qingyang, who has surpassed the realm of Dongxuan and stepped into the realm of "unknowable".

But the point is, although the asteroid is "small", it is still too big.

It is more than 100 kilometers at its longest point, and its density is a little greater than the average density of the earth, with a total mass of about 70 trillion tons.

This road was also blocked.

But suddenly, Wei Qingyang was shocked again, and a bold idea broke into his mind.

The idea is bold and crazy, but ...... You can give it a try.

Just like before he took scientific thinking, used Taoism as a means and a tool, and finally created a survey telescope and found this asteroid, monk Wei Qingyang can't take this asteroid away, it doesn't mean that scientist Wei Qingyang can't do it!

Thruster! He's going to build a huge amount of thrusters to propel this asteroid with him!

And the energy source of the thruster can be completely created by absorbing the power of the stars of this asteroid through spells and Taoism!

This thought made Wei Qingyang's mind hot for a moment.

Although he only understands the working principle of the construction of various thrusters, and does not know much about the engineering implementation scheme, it doesn't matter, the magical Dao technique can make up for it!

"Thrusters, thrusters......"

The thrusters he knows are roughly divided into two kinds, one is the conventional working fluid thruster, that is, the heating working fluid, the expanded working fluid is quickly sprayed out to obtain propulsion, and the other is the ion thruster, the principle of which is to ionize the gas first, and then use the electric field force to accelerate the charged ions and eject them, and use their reaction force to obtain the propulsion.

As for the pure non-working mass thruster, it was not manufactured in Wei Qingyang's time, and even the theoretical breakthrough was very limited, and of course he didn't know how to build it.

Among them, thrusters are divided into two types: chemical energy and nuclear power.

Each of these thrusters has its own disadvantages and advantages. For example, the traditional chemical energy working fluid thruster is simple and reliable, but the specific impulse is lower and more energy-consuming. The ion thruster saves energy and working fluid, but the thrust is too small.

Wei Qingyang didn't struggle with which propeller to choose now, that was a question that he needed to think about later. What he was thinking about now was, no matter what kind of thrusters they were, how could he engineer them?

At the same time, there is also a very critical problem, that is, even if you can use thousands of people with your heart, but to propel this asteroid, the number of thrusters required must be huge, and it may be calculated in millions, tens of millions, or even hundreds of millions, and it is unrealistic to rely solely on your own divine consciousness to manipulate.

This requires Wei Qingyang to make them work on their own, that is, they must be arranged one by one. And the key question is, is there enough formation materials on this asteroid that can carry runes and star power?

If you want to set up a formation, you must first prospect for ore.

Wei Qingyang immediately sat down, operated his mental method, and released a huge divine sense, completely enveloping the asteroid.

His divine sense is enough to cover a radius of more than three million kilometers, and it is not a problem to cover an asteroid. However, if you want to penetrate the obstacle of the physical object, you have to carefully distinguish its internal composition, which is much more laborious than in a vacuum, and the speed of consuming star power is much faster.

It took three days for Wei Qingyang to fully and thoroughly understand the structure of this asteroid.

Contrary to his expectations, compared to its size and mass, the star power material on this asteroid is quite a lot. Although their quality is not even comparable to the lowest level of heaven and earth treasures, since they are beggars, they are not qualified to be hungry, so they can just use them.

Wei Qingyang's mind moved, and the next moment, tens of thousands of stones flew up on the surface of this asteroid, converging towards Wei Qingyang on their own. After that, Wei Qingyang's body rose in the air, and his right hand pressed down, and thousands of black lines appeared from the palm of his hand, slamming into the small star body.

When the black line breaks through the inner part of the star, the top of the black line is wrapped around large and small stones.

These stones were also piled up by Wei Qingyang in the previous place.

And so on until the entire star was looted.

At this moment, in front of him, spiritual materials that could carry runes and star power were piled up into a small mountain. But Wei Qingyang didn't know how many thrusters could be made from these materials. Because he still hasn't been able to determine how much a thruster formation will consume.

Now it's time to settle on this one.

Wei Qingyang first tried a chemical thruster with hydrogen and oxygen propellant as the energy source. The reason is very simple, on this asteroid, solid hydrogen, solid oxygen, and water ice can all be found, at least in the experimental stage, you don't need to consume star power to obtain it through spells.

Wei Qingyang's idea was to burn hydrogen and oxygen, heat water ice, and use the recoil of water vapor to gain propulsion.

At this stage, there is no need to think about automatic fuel refilling, just the thruster itself.

The first is the combustion chamber, the formation called "hydrogen and oxygen thruster" constructed by Wei Qingyang must be able to isolate the combustion chamber from the outside world. This function can be achieved through a spell called "Heavenly Dungeon Net".

Of course, it's a simplified version of the dungeon-to-earth net.

But at the same time, the nets must not hinder the transfer of thermal energy. This requires some modifications to the spell. But this is not difficult for Wei Qingyang.

After the combustion chamber, the water is heated, and it must be sprayed out at a very high temperature and pressure at a very high speed to generate sufficient thrust.

Here, too, the Heavenly Prison Net will be used, but the form will have to be changed.

Hydrogen and oxygen are burned to produce water, and the circulation of water in the combustion chamber is also designed. Moreover, the rate of hydrogen and oxygen combustion must be controllable, which makes Wei Qingyang difficult.

After thinking about it for a long time, he achieved this by regulating the pressure.

The so-called Pinghai Jue, the so-called Zhenfeng Decision, are not all achieved through pressure, you can use it with a little transformation, and you must know how to be flexible.

In the case of automatic ignition, Wei Qingyang achieved this through the simplest flame technique. It is necessary to design a simple logical judgment system, and there are many such means in the formation theory, which is easy to implement.

In the end, Wei Qingyang fixed several Heavenly Prison Nets, a Wind Suppression Decision, a Flame Technique, and the rest of the other auxiliary small spells to the spiritual materials through runes, and a spell version of the chemical energy thruster was manufactured.

Taking a deep breath, Wei Qingyang started the first experiment with confidence.
