He had absorbed all the power of stars gathered by this asteroid before, allowing Wei Qingyang's reserves to quickly rise from less than half a century to 20%. Next is the water grinding skill, and he had to wait for it to gather bit by bit before he could absorb it bit by bit.

This is too slow, but Wei Qingyang has no choice.

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

The total amount of star power absorbed by the earth will not change. There are more here, less there.

Until now, this asteroid is so big in total. Wei Qingyang has absorbed the entire planet in an instant. He also needs to distinguish where there is more star power and less star power.

In addition to the slow speed of star power gathering, there is another thing that makes Wei Qingyang worried.

It is still the subsequent impact of the monster's "that blow" that came from somewhere.

Even if you are tens of billions of kilometers away from the sun, you cannot escape its influence. Staying here for a long time is still a death. Compared with the inside of the solar system, the difference is that you die faster and you die slower.

What's more, at this moment, the asteroid is slowly approaching the sun rather than moving away.

This made Wei Qingyang even more worried.

Besides that, there is one more thing.

"At the speed of the asteroid's star power gathering, it will take at least one month for me to recover from my full strength. So, what about a month later?"

Wei Qingyang, in his heyday, launched a starlight escape, which could support about five months of flight time and could fly less than 40 billion kilometers.

What after this? Find another asteroid to rest?

This is unrealistic.

From the inside to the outside, the solar system is Mercury, Venus, Earth, Mars, 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 Hills cloud, and the Ort cloud.

Generally speaking, the more outward the universe is, the more difficult it is to find macroscopic celestial bodies.

The location of Wei Qingyang at this moment is probably between the discrete eclipse of the eclipse and the Hills Cloud. Now this asteroid does not belong to the discrete eclipse of the eclipse or the Hills Cloud. It is an independent celestial body.

At this stage, it took such a huge effort to find it. Going outside, God knows if he can find a place to stay.

I can't find a place to stay. Even if I am as strong as Wei Qingyang, I will have to die in the end.

There is another possibility, that is, stay here for a long time, and after you recover from your full strength, you will continue to wait for the gathering of star power, refine the excess star power into "spirit stones" and carry it on your body for replenishment.

Spirit stones are aggregation of the power of stars, which allows monks to incorporate them into their bodies without concentration or practice. In the solar system, spirit stones, especially high-quality spirit stones, are hard currency. Whether traveling at home, killing people and catching treasures, or setting up formations, refining magic weapons, or pills, they are indispensable.

However, under the influence of the "that attack", at this distance, Wei Qingyang could live for a few more years, and the spirit stones made of star power gathered over a few years were lost after he could use them a few times.

This road still cannot be understood.

Found this asteroid only solves the urgent problem, but 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 out?"

After thinking for a long time, Wei Qingyang casually absorbed the power of stars gathered by this asteroid during this period and sighed.

"Strive" above this asteroid and looking up at the stars in the sky, Wei Qingyang murmured: "It would be great if this asteroid could follow me."

Think about it, if Wei Qingyang could take it with him, he could be replenished by the power of the stars along the way, and he would not have to worry about the power of the stars running out and dying. Even if the speed was slower, he would be willing to accept it.

But reason told him that this was impossible.

The four realms of foundation building, clouds, seas, and cave Xuan. When you reach the realm of the Underworld, you already have the ability to turn the rivers and seas. It is easy to level a mountain, let alone Wei Qingyang, who has surpassed the Daoxuan realm and entered the "unknown" realm.

But the key is that although this asteroid is "small", it is still too big.

Its longest location is more than 100 kilometers, and its density is a little larger than the average density of the earth. Its total mass is about 70 trillion tons. Wei Qingyang can do such a huge creature, but it is impossible to take it together to sail interstellarly.

This road was also blocked.

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

Although this idea is bold and crazy, you can try it out.

Just like before, he adopted scientific thinking, using Taoism as a means and a tool, he finally created a telescope in the sky and found this asteroid, the inability of monk Wei Qingyang to take away this asteroid does not mean that scientist Wei Qingyang has no choice!

Thruster! He wants to build a huge number of thrusters to push the asteroid to go with him!

The energy source of the propeller can be created by itself after absorbing the power of the asteroid's star, and then spells and Taoist techniques!

This idea made Wei Qingyang feel excited in an instant.

Although he only understands the working principle of the various thrusters and does not know much about the engineering implementation plan, it doesn’t matter. The magical Taoist technique can make up for this!

"Thruster, thruster..."

The thrusters he knows are roughly divided into two types. One is a conventional working fluid thruster, that is, heating the working fluid, and quickly spraying the expanded working fluid to obtain the pushing force. The other is an ionization thruster. The principle is to ionize the gas first, then use electric field force to accelerate the charged ions and then spray them out, and use its reaction force to obtain the pushing force.

As for pure working fluid-free thrusters, they were not made in Wei Qingyang's era, and even theoretical breakthroughs were limited. Of course, he didn't know how to build them.

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

These types of thrusters have their own shortcomings and advantages. For example, traditional chemical energy working fluid thrusters have simple and reliable technology, but have lower specific impulse and consume more energy. Ion thrusters save energy and work fluid, but their thrust is too small.

Wei Qingyang did not worry about which thruster to choose now, which is a question that needs to be considered later. What he is thinking now is, no matter which thruster it is, how should he implement them from an engineering perspective?

At the same time, there is another very critical issue, that is, even if you can use it thousands of times, if you want to push this asteroid, the number of propellers required will inevitably be huge, and may have to be calculated in millions, tens of millions, or even billions. It is unrealistic to simply rely on your own spiritual sense to manipulate it.

This requires Wei Qingyang to allow them to operate on their own, that is, they must arrange formations. The key question is, are there enough formation materials on this asteroid that can carry runes and star power?

If you want to arrange a formation, you must first prospect.

Wei Qingyang immediately sat down, used his mind method, and released his huge spiritual consciousness, completely covering the asteroid.

His spiritual consciousness is enough to cover a radius of more than three million kilometers, and covering an asteroid is no problem at all. However, if you want to penetrate the obstacles of the real 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 only three days for Wei Qingyang to fully and thoroughly understand the structure of this asteroid.

To his expectations, compared to its size and quality, there are quite a lot of star power materials on this asteroid. Although their quality is not even comparable to the lowest-level natural and earth treasures, since they are beggars, they are not qualified to think that the rice is bad, and they can just use it if they can.

Wei Qingyang's mind moved. The next moment, tens of thousands of stones flew up on the surface of the asteroid and gathered towards Wei Qingyang. After that, Wei Qingyang's body rose into the air, pressed down with his right hand, and thousands of black lines appeared from his palm and pierced into the asteroid's star body.

When the black line breaks out from the inside of the star body, stones, large or small, are wrapped around the top of the black line.

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

Repeat this until the entire star body is plundered.

At this moment, in front of him, spiritual materials that could carry runes and star power were piled up into small hills. But Wei Qingyang didn't know how many thrusters these materials could make. Because he couldn't determine how much thruster formation would consume.

It's time to determine this next thing.

Wei Qingyang first tried a chemical propeller that uses hydrogen and oxygen propellants as the energy source. The reason is very simple. On this asteroid, solid hydrogen, solid oxygen, and water ice can be found. At least during the experiment, you don’t have to consume your own star power and obtain it through spells.

Wei Qingyang's idea is to burn hydrogen and oxygen, heat water ice, and gain driving force with the backlash of water vapor.

At this stage, there is no need to consider the automatic fuel addition at the moment, just consider the thruster itself.

First of all, the combustion chamber. The formation called "Hydrogen and Oxygen Propeller" 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 "Tianzhudi Net".

Of course, it is a simplified version of the Tianzhudi Net.

But at the same time, the Tianzhuo and Earth Net cannot hinder the transmission of heat energy. This requires some transformation of this spell. However, this will not bring down Wei Qingyang.

After the combustion chamber, water is heated, so that it can generate extremely high temperatures and extremely high pressures, and spray out at extremely high speeds to generate sufficient thrust.

The Tianzhudi Net is also used here, but the form needs to be changed.

When hydrogen and oxygen are burned to produce water, the water circuit cycle in the combustion chamber must also be designed. In addition, the rate of hydrogen and oxygen combustion must be controlled, which makes Wei Qingyang difficult.

After thinking for a long time, he achieved this by adjusting the pressure.

The so-called Pinghai Jue and the so-called Fengshen Jue are all achieved through pressure. You can use it with a slight transformation. You must know how to adapt.

In the automatic ignition, Wei Qingyang achieved this through the simplest flame technique. A simple logical judgment system is needed to be designed here. There are many such means in the formation theory and it is easy to achieve.

In the end, Wei Qingyang fixed several Tianzhudi, one Fengshen, one Flame Technique, and several other auxiliary small spells to the spiritual material through runes, and a spell version of the chemical energy propeller was completed.
Chapter completed!
