Logically speaking, since the "spaceship" is a long-distance journey in the form of teleportation, then its own short-distance maneuvering ability is not very important, and if it is designed to the extreme, save energy, and reduce the body, this part can even be completely abandoned.

But the consequence of that is not to get close to any slightly larger object, otherwise once it enters the gravitational field dominated by it, it will be captured and fall to its surface.

There is no way to leave at all unless you use Teleportation to escape.

It's embarrassing, no matter where you go, you can only look at it from a distance, and then leave quickly?

It's better to crouch at home and imagine the future.

The power system must be there, but if you think about it carefully, there are many constraints on this, and the propulsion power system is a reaction force formed by the reaction of fuel, just like someone pushing it, and the origin of the name is also like this.

In order to form a reaction force, it is required that the energy or material flow released in the fuel reaction move in a unified direction, so as to achieve the goal.

However, no matter whether it is energy or matter that is released, there must be "fuel", and when the "fuel" carried by the aircraft is exhausted, it will lose power, but no matter how big the "spaceship" is, can it still carry fuel that can never be used up?

Qi Yuan didn't have a specific destination when he went out this time, for example, he would turn back when he arrived at Jupiter, so that he could calculate how much he needed and what kind of fuel was more appropriate, the problem was that he might have to go to other star systems to take a look, God knows how many times he needed to get close to the big celestial body, and how much fuel he needed to prepare was enough!

But fortunately, there is an arcane art, Zeng Li scratched his scalp and thought of two possibilities, one is to use a nuclear fusion engine, and the magic power will be directly converted into fusion raw materials by creation, so that as long as Qi Yuan masters the arcane art of making fusion raw materials, he will not run out of fuel.

But the disadvantage of this method is that the nuclear fusion engine is extremely precise and complex, and there are many disciplines involved, and Qi Yuan is only one person during the journey, he must learn all the relevant knowledge before departure, and if the engine fails, or even damaged, he must have the ability to repair it by himself.

The use of other engines is also facing this problem, aerospace instruments, none of which are "stupid, big and black", and at the same time also facing the dilemma of using arcane to make a large number of fuels, and the efficiency of any other form of material conversion energy that has been mastered so far is far less than nuclear fusion.

At the same time, solar energy is not a reliable solution, in the future, the "spacecraft" will inevitably have a time close to the star during the journey, and there will be a time far away from the star.

No matter how much time is wasted, how much weight will the "solar battery" to be installed on the "spaceship" alone?

In general, this idea is to use arcane combined with the technical means of various other disciplines to jointly complete the propulsion power system.

Another way of thinking is to use the arcane as a separate discipline to solve all problems independently.

Some people like to say that this is "arcane plus science" and "pure arcane", two ways of thinking.

Zeng Li was the first to oppose this **, arcane itself is part of science!

As long as it appears, it no longer only exists in people's fantasies, then it is no longer mysterious, and anyone who tries to pretend to be a god and a ghost is not a person who is not a person with scientific research, and it cannot be mixed in!

Arcane can be regarded as mathematics, physics, chemistry, it can also be subdivided, there are many small subjects in it, and when people understand it deeply, a big arcane will be divided into hundreds or thousands of small fields, which will be a necessary stage!

Just like the arcane spellcasters of Evangeliel, the specialization schools had become popular before the worlds merged, and the majority of them had already spontaneously begun to study separately.

Although the world is different and the rules are different, since there are similarities, people must have common choices.

After the world merged, whether it was the scholars of the earth or the spellcasters of Evan Riel, the people who studied the arcane began to give up their specialization, and instead used the whole school to study and study, not because of how talented everyone was, everyone became geniuses.

It's because of the unknown change in the rules, a lot of common sense has changed, and everyone has done general research, which helps to understand the new world more quickly, and at the same time it becomes easier to discover new results.

Combined with the original scientific system of the earth, the two sides communicate and collide, and the spark of inspiration will continue to sputter, which is the happiest era for scientific researchers!

Zeng Li felt that he could open another topic, so he just got Qi Yuan's "spaceship" out, and there were thousands of papers in various subjects, which were broken down in detail, and it was no problem to say that there were tens of thousands!

For example, the pure arcane means he is now considering to solve the propulsion power system, since the magic can directly convert heat energy and kinetic energy, is it better to design a model so that the kinetic energy of magic transformation has a natural unified direction, without having to go through mechanical transformation?

Thinking a little further, can we abandon the propulsion power system and use the ubiquitous gravitational force and gravitational field in the universe to do movements such as "gravitational field cutting", so as to achieve the purpose of generating power?

In fact, if we can really start with the four basic forces to solve related problems, then from now on, mankind will really enter the era of "interstellar voyage"!

However, this can be regarded as an pursuit, and for now, it is a subject as difficult as studying the nature of magic......

But the idea of direct transformation of power by magic can still be considered in detail, the problem is that Zeng Li himself is not good at this aspect, about energy transformation, he mainly follows the results announced by others to learn, and his main research direction is in the prophecy school.

How much of this is due to Professor Kuai's influence, Zeng Li himself can't say, but he is indeed most interested in the prophecy school, this school of arcane models is different, giving him a feeling of "asking" to infinity!

From the first detection magic to identification, he was the first to try to use it, and at that time he discovered a characteristic of the school of prophecy, there are always several rays in the model, extending from the "questioner" to infinity.

The "questioner" transforms the question and the information related to the question into an arcane model, like programming in a computer language, and finally transforms it into a zero-sum one, and the model is the assembly language of the arcane.

Zeng Li wanted to know if he would know what he wanted to know when he understood who the prophecy school was asking questions.

Can it be as one of the earth's native religions preached: omniscient and omnipotent!
