What appeared in front of Wei Qingyang at this moment were a few black or variegated stones that seemed to be placed on the ground at random. They are engraved with intricate runes, and they are also connected to each other by passages.

Such a strange-looking thing, but after Wei Qingyang's mind moved, and he issued a start-up order, it suddenly spewed out a colorless steam upwards.

Water vapor can't be seen, but Wei Qingyang can sense it.

After ejecting some distance, they dissipated into the vast universe before they could condense into mist due to cooling.

At the same time, at the edge of this formation, which Wei Qingyang named "Thruster", a large number of dull-colored stone-like things suddenly began to shrink on their own.

Wei Qingyang was shocked. But the next moment, he figured out what was going on.

The temperature inside the thruster is too high! The heat was dissipated, and immediately the elements such as hydrogen and oxygen, which had condensed into a solid state due to the low temperature, began to sublimate, and disappeared into space.

This will not work!

Now it was just a thruster formation, and in that moment just now, at least a hundred kilograms of matter were directly sublimated. If this kind of formation is spread all over this asteroid, I'm afraid that as soon as it is activated, all the sublimable materials on this asteroid will run away!

If the quality is reduced, the speed of condensing the power of the stars will be reduced, which is unacceptable to Wei Qingyang.

He subconsciously wanted to stop the operation of the formation, but before he could give the command, he saw that those stones suddenly pierced into the asteroid, and the formation immediately shattered.

"You have to consider the geological structure...... Wei Qingyang muttered in his heart.

The thrust generated by this thruster formation was too large, and the geological structure of the asteroid was not strong enough, so it plunged into it, and the formation naturally broke.

Looking at the several potholes on the ground, Wei Qingyang fell into deep thought.

Overall, your ideas should be feasible. After all, this thruster formation has really produced thrust. But there are many places to be renovated.

The first thing that must be solved is the problem of heat dissipation. If this problem cannot be solved, there will be a big problem.

"How do you fix it? Without medium, where is this waste heat discharged? ”

The cosmic vacuum is the only place where waste heat can be discharged. However, although its temperature is low, it is not able to reduce the temperature quickly because the density of the material is too thin.

In the cosmic vacuum, the only way for objects to cool down is to radiate heat to the outside world through thermal radiation. However, thermal radiation is the least efficient form of heat conduction.

After thinking for a long time, Wei Qingyang suddenly patted his head.

"Why did you walk into a dead end again, what a simple thing, can't you just add an ice spell to the formation."

The original formation has basically taken shape, and there is no room for adding more spells. In order to add it, it must be adjusted as a whole. But this is not difficult for Wei Qingyang.

After breaking up all the original spells, Wei Qingyang sorted out and placed them in a unified manner, so a brand-new "thruster" formation with the addition of ice magic was re-formed.

The next problem to be solved is that the geological structure of the asteroid is not strong enough.

Wei Qingyang intends to use violence to solve this problem.

He flew into the air, a huge divine thought emanated, his right palm slowly lifted, and then slowly pressed down.

In an instant, the ground was full of sharp stone pillars and craters, and the surface of the asteroid with an area of at least one square kilometer immediately seemed to be smashed by a 10,000-ton hammer.

This ability can be achieved by cultivating monks who have entered the realm of "pouring the sea", and the so-called destroying mountains and mountains, turning rivers and seas, is a very appropriate description of this realm.

Used in the hands of Wei Qingyang, who is in the "unknowable" realm, its power is not known how many times greater than that of the cultivators of the Fallen Sea Realm.

Wei Qingyang did not immediately level the rest of the place, but once again arranged an improved version of the thruster formation on the surface that had been leveled.

Sure enough, this time, the surface of the ground was not dented by the thrust of the thrusters, and the solid hydrogen, oxygen, and water ice in the surrounding areas did not melt due to waste heat.

Improvements have been initially successful. After that, Wei Qingyang tested the thrust of this thruster, and after a simple calculation, his brows furrowed again.

The specific impulse is too low, the thrust is too small, and the energy consumption is more than they expected.

If the current version of the thrusters were to be arranged, I am afraid that all the surface of this asteroid would be equipped with thrusters, and the thrust generated would not be enough to make it break free from the sun's gravity. What's more, its energy consumption is too high, and the solid hydrogen and oxygen stored on this asteroid are simply not enough to support subsequent consumption.

"It still needs to be improved."

The initial version was named version 1.0 by Wei Qingyang, and the version with the addition of ice magic was named version 1.1, and now, Wei Qingyang is immersed in the development of version 1.11, or version 1.2.

He had to increase his thrust tenfold while reducing his energy consumption to one-seventh in order to achieve his goal.

It's a daunting task. Even if he cultivated the formation of the first person in Wei Qingyang's solar system, he felt very tricky.

There was no choice but to sit down cross-legged, enter a state of concentration, and begin to deduce and calculate in his mind.

But after deducing for a long time and finding nothing, Wei Qingyang opened his eyes a little irritably, and muttered: "It's really not good, just change to ion thrusters?" ”

The efficiency of the ion thruster is the highest. In this regard, it will almost certainly meet Wei Qingyang's requirements. But the next moment, Wei Qingyang denied this idea.

It's too precise, Wei Qingyang can't make it at all. What's more, even if it is built, its thrust is too small, and it will not be able to meet its own requirements.

Things still have to fall on the conventional high-thrust thrusters.

Or...... Nuclear power? ”

Fission energy doesn't have to think about it, there is no fissile material here. Among the spells that Wei Qingyang knew, there was no one that could create fissile materials.

In the battle of cultivators, no one would think of killing people by nuclear radiation.

Then it can only be nuclear fusion. Speaking of nuclear fusion, there is quite a lot of solid hydrogen on this asteroid, which can meet the requirements.

Although hydrogen is not the best fuel for fusion, it can be used.

The only key is whether the project can be realized.

In the world of the previous life, controlled nuclear fusion was realized, using laser ignition. However, Wei Qingyang thought back to the fire spells he had mastered, and still shook his head regretfully.

Among the fire spells, the hottest should be the Burning Sky Fire, which is claimed to be able to burn all the existence in the world. In reality, it is true, no matter what it is, it can't withstand its burning. However, its temperature is only 80,000 or 90,000 degrees in the sky, not even 100,000 degrees, and it is still far from the requirements of nuclear fusion.

This Burning Sky Fire was developed by Wei Qingyang himself at the beginning, and it was the secret of the Qingyang Sect. Some outstanding core disciples relied on this spell to dominate the rivers and lakes and made great achievements for the sect, and the rest of the sect monks were all discolored.

But now the eggs are not used.

It is also impossible to rely on technical means to achieve nuclear fusion. Its ignition device and maintenance device are too precise for Wei Qingyang to build.

"There are still too few types of spells, and the understanding of the formation is too superficial, and the slightly more sophisticated instruments and equipment, uh, should be called formations now, and they can't be realized at all. In the future, we will have to continue to strengthen our research. ”

Wei Qingyang sighed deeply.

If there are still people alive in the solar system and know Wei Qingyang's idea, I am afraid that they will be angry to death.

You are the first person in the solar system, and you still complain about your superficiality, how can others live?

But thinking of this, Wei Qingyang's heart suddenly moved.

He vaguely found the direction to improve efficiency and reduce energy consumption.

In previous lives, people wanted to do this, usually in the direction of improving accuracy. For example, some machines have even higher than a few nanometers or even smaller requirements for errors. Myself...... Could we also develop in this direction?

With this idea, Wei Qingyang's train of thought was immediately opened.

"The accuracy of Pinghaijue needs to be adjusted, and it needs to be more precise."

"Two heavenly nets can be one."

"The combustion chamber and water circulation piping need to be optimised to make the best possible use of heat."

"Well, the waste heat is less, and the strength of the Ice Technique can be reduced."

……

Three days later, Thruster version 1.2 was finally released. After the experiment, Wei Qingyang came to an exciting conclusion.

Its thrust has been increased by six times, and its energy consumption has been reduced by one-fifth. Although it has not fully met its requirements, the results are gratifying enough.

This at least proves that he is on the right track.

In the next few days, Wei Qingyang continued to use his brain, adjusting the structure of the thruster formation little by little from more subtle places, optimizing its efficiency. Version 1.21, version 1.22, version 1.30, until version 1.45 thruster was developed, its performance indicators finally met Wei Qingyang's requirements.

"Hoo ......"

Looking at the few inconspicuous stones that seemed to be placed randomly on the flat ground, Wei Qingyang let out a deep sigh.

"So...... It's time to get started. ”

Next, Wei Qingyang frequently began land leveling work. With each movement, at least one square kilometer of land is leveled and compacted. But even then, it took him thousands of spells to completely transform the asteroid's sun-facing side.

After that, it's time to set up the formation. Even if he could use thousands of dollars at once, the work would have taken him more than a full year.

There is no way, there are too many formations that need to be arranged, up to tens of millions.

With Wei Qingyang's order, these tens of millions of formations began to work one after another.

Endless amounts of water vapor are ejected into space, and the huge thrust they produce is slowly changing the asteroid's orbit.
