10 kilometers.
50 kilometers.
100 kilometers.
Unlike a rocket, the Obsidian Spaceship did not need a strong thrust to overcome the effect of gravity, so it maintained a very high ascension speed. Unknowingly, the Obsidian Spaceship had risen to an altitude of about 400 kilometers above the ground.
At this height, the atmosphere was very thin, close to a state of vacuum.
And everyone was already in a state of weightlessness.
For Xia Ruofei and the others who were wearing the spacesuits, the weightlessness seemed to be more relaxed. Although the bulky spacesuits still looked bloated, they seemed to be weightless.
Sound could not be transmitted in a vacuum.
However, Xia Ruofei and the others did not need to use their mental power to transmit sound because the spacesuits were equipped with an intercom system. Everyone had set the frequency to the same channel in advance, so they could talk directly on the same frequency.
Xia Ruofei said, "We're just testing the flight. I think it's enough to maintain this orbital altitude. This is about the same altitude as our country's Heavenly Palace Experiment Module. Brother Chen, what do you think? "
Chen Xuan made an OK gesture and said, "Okay!"
This test flight was led by Xia Ruofei, so naturally, no one had any objections.
So Xia Ruofei said, "Then I'll release the spaceship!"
After that, he first used his mental power to control the control panel of the Obsidian Spaceship and expanded the shielding boundary of the spaceship by about 20 meters. This was almost the maximum range of the shielding boundary of the spaceship. Maintaining such a large boundary for a long time would also consume a lot of crystals. But Xia Ruofei still had to do this. Otherwise, if the spaceship was released rashly, many countries would probably be the first to notice that there was an unknown aircraft in the 400-kilometer orbit. Therefore, the spaceship had to be included in the shielding boundary.
After adjusting the boundary of the Obsidian Spaceship, Xia Ruofei took the dragon spaceship out of the Ring-Tu space.
The Dragon Spacecraft instantly appeared next to the Obsidian Spaceship. At this time, the Obsidian Spaceship was maintaining an orbit of 400 kilometers around the Earth. The Dragon Spacecraft and the Obsidian Spaceship were in a relatively static state.
Xia Ruofei connected the Dragon spacecraft and the Obsidian spacecraft with two straps. These straps were the kind of safety rope used by astronauts for extravehicular activities. There were several straps in every extravehicular spacesuit accessory box. Now that the two spacecraft were in a relatively static state, there would not be any pulling force. It was enough to make a simple connection with these straps.
Moreover, even if the Obsidian Airship and Dragon Ship drifted far away in space, Xia Ruofei could still control the Obsidian Airship to chase after them. They definitely wouldn't get lost in space.
Xia Ruofei smiled and said, "Fellow Daoists, I'll go first!"
After that, Xia Ruofei lightly stepped on the deck of the Obsidian Airship and floated towards the Dragon Spacecraft.
Xia Ruofei didn't take any safety measures. He directly grabbed a fixed rod on the outside of the spacecraft and waved to Chen Xuan, Ling Qingxue, and the others on the deck of the Obsidian Airship behind him.
If it were an ordinary person, it would be impossible for them to enter a sealed spaceship in space.
In fact, in space flight, if the hatch of the spacecraft was directly opened from the outside, it was estimated that the strong pressure difference between the inside and outside of the spacecraft would directly blow the hatch open. When astronauts went out of the spacecraft, they first came to the sealed cabin section and then decompressed this section to make the cabin section become a vacuum with no pressure difference with the outside. Only then could they open the hatch.
Of course, this was not a problem for cultivators.
Xia Ruofei grabbed the fixed rod on the outside of the Dragon Spacecraft with one hand and then directly extended his mental power into the spacecraft's return cabin. The return cabin was also the cockpit of the spacecraft. All the controls were done here.
Although the power system of the spacecraft had been dismantled, some basic control units were still intact. Otherwise, the spacecraft would become a big jar that could not meet the needs of living in space.
Xia Ruofei directly used his mental power to remotely control the spacecraft according to the operation manual. He directly turned on the main power of the spacecraft and unfolded the solar panels to ensure that the spacecraft had an adequate power supply.
Then, he pressed the button to decompress the cabin he was about to enter.
After doing all this, Xia Ruofei directly used his mental power to pull the handle of the hatch and opened the airtight hatch.
Then, Xia Ruofei easily pushed it in and lightly entered the interior of the spacecraft.
Xia Ruofei briefly checked and then said, "Everyone, come here!"
Chen Xuan and the others also jumped off the Obsidian Airship and easily came to the top of the Dragon Spacecraft. Then, they filed into the interior of the Dragon Spacecraft.
Five people wearing spacesuits suddenly squeezed into the cabin, making it seem a little crowded.
Xia Ruofei quickly closed the airtight hatch and then extended his mental power into the cockpit to check the airtightness of the cabin. After confirming that the hatch was closed and there were no problems with the airtightness, he pressurized the cabin.
Soon, the pressure in this cabin was the same as the other cabins.
Xia Ruofei opened the hatch to the other cabins and said, "Okay, everyone can take off the extravehicular spacesuits. But those who are in the Qi Condensation stage, please wait a moment. Brother Chen, Elder Yang, and I will go first!"
Xia Ruofei and Chen Xuan were both in the Aurous Core stage. If there was a problem with the oxygen content in the spacecraft or other dangers, their survival ability was far stronger than that of the Qi Condensation stage cultivators.
Xia Ruofei and the other two followed the procedure and took off their extravehicular spacesuits.
They tried to take a few breaths and felt that it was not much different from the ground. It was just that in the state of weightlessness, they felt a little uncomfortable. However, there was no problem with the environment inside the spacecraft. At this moment, even if an ordinary person from the secular world appeared on the spacecraft, they would still be able to survive very well.
Therefore, Xia Ruofei gestured to Ling Qingxue and Yu Xin 'er.
The two of them also couldn't wait to take off their extravehicular spacesuits.
There was already air in this cabin, so everyone could talk directly to each other.
Xia Ruofei said, "Originally, in order to ensure that everyone can change into their extravehicular spacesuits and quickly escape from the spacecraft when there is danger, all the spacesuits are designed to be left in this cabin. However, everyone has their own storage magic treasures, so it's better to put away your spacesuits. This way, there will be more space in this cabin!"
Everyone nodded and put away their extravehicular spacesuits into their respective storage magic treasures.
Then, Xia Ruofei led everyone to wander around the interior of the spaceship.
These cultivators were still a little uncomfortable with the weightlessness of the environment. They always felt that they were floating under their feet, and they had no concept of up and down. Therefore, when they moved forward, they stumbled. Fortunately, when the spacecraft was designed, some of the places that were easy to bump into were used. The protection was quite good.
Xia Ruofei and the others walked around and found that although these expansion cabins were not very big, the design was very reasonable.
For example, there were two resting cabins, so that men and women could be separated. Of course, the so-called resting cabins were actually sleeping bags fixed to the wall. Because there was weightlessness in space, there was no distinction between up and down, so everyone felt the same whether they were standing or lying down.
There were also special bathing and toilet areas on the spacecraft.
In addition, because there was no need to carry a large number of living materials, and there was no need to undertake tasks such as on-orbit scientific experiments, there was naturally no need to carry experimental equipment, so a lot of space in the cabin was saved. Xia Ruofei simply estimated that even if there were a few more people, overall, the space was still relatively spacious.
Of course, this was all relative. If compared to the ground, the interior of the spacecraft was definitely cramped.
Everyone practiced some basic operation procedures several times according to the operation manual of the spacecraft. This was also the most basic requirement. In a voyage of one or two months, anything could happen. Naturally, everyone needed to be able to perform the basic operations of the spacecraft independently.
Fortunately, everyone was a cultivator, and such operations were not particularly difficult. The main test was memory, so everyone quickly mastered it.
Xia Ruofei and the others stayed in the spacecraft for about half an hour, then they all put on their extravehicular spacesuits and returned to the orbital cabin that entered and exited the spacecraft.
Xia Ruofei locked the cabin door leading to the return cabin, then used his mental power to control the spacecraft's buttons to depressurize the cabin.
Then, they opened the cabin door and left the spacecraft in a single file, returning to the Obsidian Flying Ship.
Xia Ruofei did not immediately put away the spacecraft, but began to set up a formation on the exterior of the spacecraft.
The main thing was a simple shielding formation. For Xia Ruofei, the formation itself was not difficult. The real difficulty was that he needed to prepare the formation materials in advance and fix them on the exterior of the spacecraft, and these formation materials must be able to adapt to the relatively harsh environment.
When Xia Ruofei was in the United States, he had already asked Li Yifu to prepare in advance.
The material he used was a kind of nephrite. Although its hardness was not very high, its ductility was the best among the jade materials. Even if the temperature changes were very large, it would not easily crack.
Xia Ruofei inlaid the nephrite talismans that he had engraved in advance on the surface of the spacecraft one by one. For exiting the cabin, many grooves and handrails were designed on the exterior of the Obsidian Flying Ship. Xia Ruofei placed the talismans one by one according to the local conditions. After checking it, he returned to the interior of the spacecraft.
At this time, the spacecraft's cabin door was not closed yet. Xia Ruofei skillfully entered the cabin, closed the cabin door, and pressurized the cabin.
Finally, he came to the cockpit. This was the control center of the spacecraft. Xia Ruofei also arranged the core of the formation here.
Although he was wearing a bulky extravehicular spacesuit, Xia Ruofei relied on his mental power to directly operate the formation, so it did not affect his speed. He skillfully arranged the control core of the formation, inlaid a crystal on the control core, and then left the spacecraft.
The main function of this formation was to shield the spacecraft. This way, the monitoring equipment on Earth, satellites in orbit, space stations, and so on would not be able to detect the spacecraft. Even if it was visible to the naked eye, ordinary people would not be able to see it.
In this way, the Obsidian Flying Ship did not need to always open the shielding barrier to the maximum. When the shielding barrier was opened to the limit, the consumption of crystals was very large. If it was just a little waste, it would not be a big deal. But when the round trip was as long as one or two months, the waste was not just a little bit of crystals. So Xia Ruofei naturally had to improve it.
After directly arranging the shielding formation on the spacecraft, a single crystal could be used for one or two months. This kind of consumption was basically negligible.
In fact, the shielding formation could use spirit crystals, but Xia Ruofei did not want to frequently replace spirit crystals, so he directly used crystals.
This way, he only needed to control the opening and closing of the formation. He basically did not need to worry about the depletion of the formation's energy during the whole voyage. It was almost maintenance-free.
After Xia Ruofei left the dragon spacecraft, he did not immediately put away the dragon spacecraft.
Similarly, he closed the cabin door and used his spiritual power to remotely control it. He pressurized the cabin again and turned off the power supply to the spaceship. However, he did not put away the solar panels. The Mountain and Sea Realm in the Spirit Map space was spacious enough. There was no need to put away the solar panels to save space. Moreover, if the solar panels were put away frequently, it would increase the risk of failure. Directly keeping the solar panels in an open state should be the most stable.
After doing all this, he put the dragon spacecraft into the Ring-Tu space and temporarily turned off the shielding formation of the spacecraft.
Xia Ruofei returned to the Obsidian Flying Ship and immediately reduced the range of the shielding barrier. Then he smiled and said to everyone, "Okay, everyone's first space experience is over! It's time to return! The second batch of passengers is waiting to board the spacecraft! "
Everyone's relaxed laughter came from the channel.
To be honest, when the two cultivators first boarded the Obsidian Flying Ship, Ling Qingxue and Yu Xin 'er were still a little nervous. After all, space was full of unknowns. For them, fear was inevitable.
However, after about an hour of experience, this fear had weakened a lot, and they felt more confident in their hearts.
Xia Ruofei controlled the Obsidian Flying Ship to begin to descend and find a suitable trajectory. While descending, he controlled the flying ship to fly in the direction of the capital of Huaxia.
The speed of the flying ship's descent was very stable, which was also thanks to Xia Ruofei's precise control. After all, as the altitude decreased, the earth's gravity gradually began to take effect. If there was no control, the speed would definitely be faster and faster. However, under Xia Ruofei's control, the flying ship could basically maintain a uniform speed of descent, which greatly increased the comfort of the "passengers".
At an altitude of about three thousand meters, the flying ship had accurately descended and reached the sky above the capital of Huaxia.
Xia Ruofei controlled the Obsidian Flying Ship to hover in the air, and then everyone changed out of their extravehicular spacesuits. The oxygen content at this altitude was enough, and the temperature was also within the range of ordinary people. Naturally, there was no need for spacesuits to provide protection.
The spacesuits that everyone changed out of were not put away but left on the deck of the Obsidian Flying Ship. This was because the next batch of exploration team members would soon board the flying ship, and they still needed to use these spacesuits.
After changing, Xia Ruofei controlled the flying ship to continue to descend and steadily hover a few meters above the courtyard house in Liuhai Lane.
