The success of the subspace engine is crucial to the civilization of all worlds.

Because only after they possess the subspace engine can they begin to explore the universe in a real sense.

That's right, it doesn't mean that as long as you have a spaceship, you can start exploring the universe.

The reason is simple, because you have a very high possibility of getting lost in the universe.

When moving around the planet, it's easy to say, because you can detect the existence of the planet and lock in a general direction.

But there are actually not as many planets in the universe as you think.

Most of it is a dark void area.

If you are driving a spaceship and accidentally fly too far and leave the area where the position of the planet can be locked, it will be bad.

Because you will find that no matter where you look, it is completely dark.

Moreover, without planets, you lose the most important reference point for flying in the universe.

In this state, surrounded by nothingness, you may not even notice that you have deviated from the original flight route, and you have lost your way invisibly.

At the same time, the universe is vast. After completely losing your way, if you are unlucky and cannot find a planet with an atmosphere for you to dock and obtain supplies, you will basically be dead.

Therefore, before this, Luo Ji did not dare to easily send people to explore the galaxy where he was located.

At most, they can move within the range that can lock the reference object of the planet. As for the more peripheral areas, he has only sent some unmanned reconnaissance aircraft.

But unfortunately, the working time of the unmanned reconnaissance drone was limited, and judging from the results, it did not allow him to obtain too much intelligence information.

After failing to achieve any results several times in a row, Luo Ji gave up the idea of ​​sending out unmanned reconnaissance planes.

As for why we could reach Venus and Jupiter before...

It's simple, because of Venus and Jupiter, he confirmed and locked the coordinate position.

At the same time, another very important reason is that Luo Ji did not place Venus and Jupiter too far apart.

On the moon side, they can actually lock the positions of Venus and Jupiter from a distance.

This is just like people sailing on the sea, looking for the North Star to identify their direction. This, to a large extent, ensures that they will not lose their way on the way to Venus and Jupiter.

Up to this stage, what their civilizations of all worlds can do is to take fixed routes and travel between the main planet, the moon, Venus and Jupiter.

You can't fly around in other places, otherwise you will get into trouble if you are not careful.

According to the current state of the civilization of the world at that time, once something happened, there was basically no way to save it. Unless you were really lucky, you would have to wait for death.

But things are different now.

The emergence of subspace engines will completely break this situation.

Are you lost in the universe?

It doesn't matter! Just lock the interstellar coordinates of their civilization in all worlds, then open the space door through the subspace engine, and shuttle back directly!

This can be said to have largely avoided the possibility of them getting lost in the universe.

But this subspace engine is really expensive...

The previous cost of a magic power furnace was already astronomical, and this subspace engine was three times more expensive than a magic power furnace.

At this stage, Luo Ji has no plans to build more.

Not because it’s expensive!

It's because he feels that the subspace engine may be one of the key points to break through the gold rank.

In other words, if he produces a large number of subspace engines, it is very likely that he will be promoted.

Does Luo Ji want to be promoted?

This must be what he was thinking, especially after experiencing the previous all-out war and seeing the combat power of super-sized bosses, Luo Ji fully realized that they had almost no power to resist in front of these super-standard bosses.

.

This feeling of having no control over one's fate is not very pleasant.

So he can never sit still and wait for death.

but not now……

At this stage, Luo Ji has no intention of getting involved. It is wise to develop in a low-key manner and quietly accumulate strength!

Of course, in addition to this, another small reason is that the current subspace engine technology of their civilization is not particularly mature, and there are still a lot of small flaws. Ye Xuan estimates that there will be improvements in the future, which is not necessary.

A large-scale update was carried out in a hurry.

After confirming this policy, in the following development time, Luo Ji only built thirty exploration spacecraft equipped with subspace engines one after another to carry out galaxy exploration missions, and then did not continue

has grown.

As for the battleships, there has not yet been a large-scale update.

Just like that, time flies...

"This is the exploration spacecraft No. 013. This is the exploration spacecraft No. 013. Please answer when you receive it!"

In the dead silence of the void, an exploration spacecraft with a length of 1,500 meters was flying at a stable speed.

Don’t think that the scale of the exploration spacecraft is small.

In fact, its scale is large precisely because it is an exploration spacecraft.

Because for an exploration spacecraft, besides exploration capabilities, what is the most important thing?

It’s battery life!

The universe is so big. If you go out on an exploration mission and then withdraw after ten or eight days due to lack of resources, the result will be a lonely exploration.

Therefore, to explore the interior of the spacecraft, it must carry a sufficient amount of materials and even form a stable internal circulation to ensure that it has the ability to perform long-term missions in the universe.

Under this premise, the size of the spacecraft is naturally not much smaller.

"This is spaceship 014, got it!"

"This ship has discovered an unknown planet and requests assistance."

While talking, the 013 exploration spacecraft directly synchronized the intelligence information.

Exploring the unknown universe is, after all, a mission with certain risks, so exploration spacecraft are usually carried out in groups of two, so that if anything happens, they can take care of each other.

However, in order to increase the efficiency of exploration, even two exploration spacecraft in the same group do not completely work together.

Instead, they carry out separate operations within the communication range of each other.

Now that the news has been received and the synchronized information has been confirmed, spacecraft 014 has also rushed over as quickly as possible to rendezvous.

During this process, the 013 exploration spacecraft, which maintained a safe distance from the unknown planet, did not approach easily. After all, approaching an unknown planet without authorization is actually a very dangerous move.

Inside the exploration spacecraft No. 013, the crew and captain did not appear too nervous or excited.

Their civilization of all realms has been exploring the universe for more than a hundred years.

Of course, it is impossible for them to discover only one planet like this in the past hundred years.

But it is a pity that after Venus and Jupiter, their civilizations from all over the world have not been able to find a new planet with an atmosphere suitable for human habitation...
