Five hours is either long or short.

The main planet space station, which had confirmed the news in advance, received the landing signal and detected fluctuations in the space magnetic field, and the fixed space door outside the main planet quickly opened.

Not long after that, after almost five hours of subspace flight, the transport spacecraft flew steadily out of the space door.

After the news came back, there was a lot of joy outside the Lunar Space Station!

At this time, all the members of the project team, including Cheng Hao, could finally let go of the big stone that was weighing on their hearts.

After that, the most important thing is to build fixed space channels to Venus and Jupiter respectively.

Luo Ji went directly to the Lunar Space Station and discussed the matter with Cheng Hao and the others.

After completing the construction of the space channel between the moon and the main planet, the next step must be Venus and Jupiter. For this situation, everyone has been mentally prepared for this situation. Even the preliminary plan has been prepared. There is nothing surprising.

of.

At this stage, the plan generally has two ideas.

One idea is to build a space channel directly from the 'star port' outside the main planet, directly leading to Venus and Jupiter.

Another idea is to build a space channel from the moon's "star port" to connect Venus and Jupiter to form a route.

The so-called 'star port' is the abbreviation of star port, which is similar to a ship port, except that this port is built outside the planet.

Next to the star port, there is usually a large space station, which can allow the spacecraft to unload cargo or replenish supplies, thus saving time and consumption in entering and exiting the atmosphere.

Coming back to the topic, the advantage of the first idea is that it is the shortest route and can reach the final destinations of Venus and Jupiter at the fastest speed.

As for the second idea, the road will be a little longer, because if they do this, they must first reach the moon from the main planet, and then transfer from the moon to Venus or Jupiter.

Luo Ji didn't think much about it and directly chose the second idea.

That is to say, let the moon serve as a transit station and build a space channel.

Although this will increase the travel time and distance, it is better than passing by the moon.

It may be strange to say this, but as long as you think about it...

A large transport spacecraft will unload part of its supplies on the moon. After unloading, the remaining supplies will be transported to Venus or Jupiter.

If Luo Ji comes up, he will build the shortest route directly from the main planet.

Then the transport spacecraft will not be able to pass by the moon to unload the cargo. At that time, it may be necessary to mobilize an additional spacecraft to come over, or transport it in two times, which will be very inconvenient to go back and forth.

On the contrary, tying all the planets into one route seems to increase the distance, but considering practicality, this route is actually better.

As for building various direct routes in the future, we have to wait for these two routes to be built first.

After the matter here came to an end, Luo Ji also prepared to leave that day and return to the main planet.

Cheng Hao, on the other hand, continues to stay at the Lunar Space Station to assist in the construction of subsequent space passages.

Although the main job of mages should be to practice magic.

But at this stage, Luo Ji had no other option. The number of space mages was indeed scarce. Although there were some first-level space mages, they were basically of no use in this project.

As for the mid-level space mage, at this stage, Cheng Hao is the only one among them in the civilization of all realms.

As a great contributor to the development of the space channel, Luo Ji took advantage of the situation and gave him an elixir of immortality.

In terms of lifespan, it is naturally not a problem, but over the years, Cheng Hao has been busy with these projects and probably doesn't have much time to practice properly. This makes Luo Ji really worried.

Faced with Luo Ji's concerns, Jie Zichuan, who came with him specifically to confirm the situation of his students, said directly...

"Your Majesty actually does not need to worry about this problem. Although Cheng Hao has not been able to devote himself wholeheartedly to magic practice in recent years due to project reasons, in fact, the development of space channels can also deepen his understanding of space. From a certain point of view,

To a certain extent, this is actually a kind of practice."

After all, Luo Ji was still an outsider when it came to magic cultivation. Now that he had received Jie Zichuan's assurance, he naturally relaxed immediately.

After Luo Ji returned to the main planet, he quickly devoted himself to other work.

As for the lunar space station, after gaining enough experience, they naturally became more comfortable building space passages to Venus and Jupiter.

Taking into account some of the conditions of the two planets, priority was given to building the Jupiter side.

The distance between the moon and Jupiter and the complexity of the space channel determine that this will be a huge project.

Even under the premise that a successful experience has been accumulated, this space channel cannot be successfully built in just a few years.

In fact, it took them fifteen years to successfully build the space passage from the moon to Jupiter!

For Luo Ji, fifteen years was naturally not worth mentioning and passed by in a snap.

But for most ordinary people, it is really too long!

After this long-distance space channel is completely completed and officially opened to traffic, the transportation from the main planet to Jupiter will be at least dozens of times more convenient than before!

Now they set off from the main planet and make every effort to reach Jupiter in just twenty-five days.

This change in time can be regarded as a qualitative leap.

After all, it is a cross-planet level movement. Unless technological power or space spells make new breakthroughs, it will be almost impossible to make this movement efficient and make new breakthroughs in the short term.

In any case, after this, materials and manpower can be transported more efficiently between the two planets.

Over the years, the cities Luo Ji had deployed on Jupiter had been managed by Ye Hua in an orderly manner.

But there are undoubtedly still some problems in those cities left behind by the magical civilization.

Due to some restrictions due to the special circumstances on Jupiter, in these years, Ye Hua has not only collected and collected statistics on the 'legacy' of those magical civilizations.

As for the urban buildings themselves, he actually didn't do much to rectify them, or in other words, he simply didn't touch them.

It's not because Ye Hua is lazy or lacks ability.

But those golden cities deployed by Luo Ji also require a lot of manpower and resources to maintain.

With the main planet at the rear unable to provide efficient assistance, for Ye Hua, just to manage and maintain these golden cities, the current manpower and material resources on his planet have almost reached saturation.

Therefore, it is difficult for him to allocate large amounts of manpower or equipment to carry out large-scale rectification of those magical and civilized cities.
