Other practitioners who stayed in the Siheyuan had already looked up in the yard.

Chen Xuan and others also stood on the deck of the Obsidian Flying Boat and waved to the people below.

Chen Nanfeng saw his son standing intact on the side of the boat, and a smile appeared on his face.

It is definitely impossible to say that they are not worried. Although they also took the Obsidian Flying Boat once last time, they were far from reaching the 400-kilometer orbit. And because there was no out-of-cabin spacesuit at that time, they did not stay for so long.

This time, the verification flight can basically simulate the situation on the way to the moon. If there is any problem with any link, it will definitely be exposed, and the personnel also have a certain degree of safety risks.

Therefore, from this perspective, the risk factor of the first batch of people participating in the verification flight was much larger than that of the second batch.

Xia Ruofei and others jumped off the Obsidian Flying Boat, Chen Nanfeng went forward and asked, "Fellow Daoist Xia, is everything going well?"

Xia Rufei nodded with a smile and said, "No problem! Our solution should be feasible! We have tested the performance of the extra-cabin spacesuit and the functions of the spacecraft in all aspects, which are similar to what we expected. It should be no problem to support us to travel to the moon!"

When Liu Mansha saw that Elder Yang Liu and his beloved disciple Yu Xiner in Feihua Valley were unscathed, she felt relieved. After hearing Xia Rufei's words, she asked: "Fellow Daofei, it will take at least one or two months to travel to the moon! The durability of that spacecraft..."

Xia Rufei smiled and said, "I asked the American that the Dragon Spacecraft was designed to operate in orbit for at least one year, so it can operate in space environment for a long time. Lord Liu Gu can rest assured that the scientific and technological level of the secular world has been reached long ago. The Mir space station was in service for fifteen years, and it was built in 1976. Human technology had reached this level decades ago. The International Space Station, which is now operating in orbit, is also operating in orbit for a long time. The design and construction of the Dragon Spacecraft uses more advanced technologies and materials, and it is absolutely no problem to support it for several months, unless it encounters force majeure factors such as meteorite impacts, causing serious damage."

Chen Xuan also smiled and said, "Meteorite impact is a low-probability event. I am worried about space garbage... However, space garbage is mainly distributed in low-Earth orbit. After staying away from the earth, space garbage will almost no longer exist, and everyone's mental power is not a decoration. If you really encounter the risk of impact, you can definitely detect and avoid it in advance!"

Chen Nanfeng smiled and said, "Since that's the case, then we'll be relieved!"

Liu Mansha also nodded with a smile and said, "It seems that Fellow Daoist Xia has considered these factors a long time ago, but we have extra worries!"

Xia Ruofei laughed and said, "There are too many unknown situations in space, and it is necessary to prepare for the future. And unexpected situations can never be completely avoided. We still have to adapt to the situation. So we should do our best to prepare. As for the risks... If we are afraid of risks, why should we form this expedition team!"

Xia Rufei's words were very tempted by Mu Sheng's appetite. He laughed a few heartily and said, "Cultivation is fighting with the heavens. Cultivators pursue immortality. This itself conflicts with the rules of the heavenly way! There are great risks and naturally great opportunities. Brother Xia, to be honest, I envy you very much! If I can pass the screening, even if this old bone is buried on the moon, I must have a walk! Hahaha!"

"The father's business and son inherit, and Brother Jianfei will go to the moon on your behalf, and it's the same!" Xia Ruofei said with a smile.

Then, he turned his eyes to Mu Jianfei and others, and said, "Elder Mu, Elder Chen, Brother Jianfei, Miss Yurou, please board the boat! Let's start the second verification flight right away!"

Mu Hua and the other four smiled and nodded. They were feeling much more relaxed at this moment. After all, Chen Xuan and the others had already walked by.

Xia Ruofei saw that the four of them had already jumped onto the flying boat, so he smiled and said to Chen Nanfeng and others: "Three seniors, I will accompany Elder Mu and the others for another trip!"

"Thank you for your hard work!" Chen Nanfeng smiled and nodded.

Mu Sheng and Liu Mansha also nodded to Xia Ruofei. Mu Sheng looked up at Mu Hua and Mu Jianfei standing on the side of the Obsidian Flying Boat, and loudly reminded: "Be careful after going up, be careful. Follow the arrangements of Brother Xia, and do not act without authorization!"

"Yes!" Mu Hua and Mu Jianfei bowed and replied quickly.

Xia Ruofei bowed to everyone, and then flew into the flying boat.

The next process was the same as before. Xia Rufei drove the flying boat to a height of 5,000 meters, asked everyone to change into an out-of-cabin spacesuit, and then headed straight for the 400-kilometer orbit.

In orbit, Xia Rufei released the dragon spacecraft, connected it with the Obsidian flying boat, and then took everyone into the interior of the spacecraft.

Unlike the last time, Xia Rufei no longer needs to adjust the shielding barrier range of the Obsidian Flying Boat this time, he just needs to activate the shielding formation that comes with the spacecraft.

At the same time, he no longer needs to turn on the solar windsurfing board, because the windsurfing board has always remained open.

Therefore, Xia Rufei just used his mental power to remotely turn on the main power switch of the Dragon Spaceship, and after decompressing the cabin into the cabin, he opened the cabin door and took the lead in getting into the spaceship.

The stay time in orbit this time was similar to last time. Xia Rufei asked everyone to practice the basic control of the spacecraft several times on the spot, and took everyone to familiarize themselves with the various cabins of the spacecraft, practiced the process of entering and leaving the cabin, and took everyone away from the spacecraft and returned to the ground.

Chen Nanfeng and others also drove the flying sword to the obsidian flying boat and carefully checked the flying boat.

The final result also made Chen Nanfeng and others relieved - the Obsidian Flying Boat has been verified for two flights without any damage, which fully demonstrates that the material of the Obsidian Flying Boat is strong enough to cope with the harsh environment in space.

As for the Dragon Spaceship, after Xia Rufei's explanation, everyone no longer worrys whether it can run in space for a long time.

...

In the next few days, everyone was waiting patiently.

Everyone used this period to be familiar with the control manuals of spacecraft and out-of-cabin space suits. During this period, Xia Rufei also organized everyone to take the Obsidian Flying Boat to the 400-kilometer orbit twice according to the last group.

The practitioners have very strong learning ability. With these practical practices and the constant time to learn the operation manual, basically everyone has mastered the basic operation of the spacecraft and the use of out-of-cabin spacesuits, and is also familiar with some precautions for living in space.

This knowledge is likely to be used in the actual journey to the moon, and may even save your life, so everyone faces learning with a very serious attitude.

In addition to daily study, Xia Rufei also took the time to go out.

The purpose this time was very simple. He wanted to send Song Wei away first, and not to let Song Wei go back to school or home in Sanshan, but to send him directly to Taoyuan Island to live temporarily.

This mission to the moon will take at least one or two months. Xia Rufei and Ling Qingxue both entered the expedition team list, but Song Wei could only stay on Earth because she did not pass the screening of the music.

Xia Rufei was still not very relieved about Song Wei's safety.

After all, Jindan seniors like Chen Nanfeng, Mu Sheng, and Liu Mansha also stayed on the earth.

It is still unknown what kind of opportunities will be during the adventure. Xia Rufei has to consider whether the forces that are still in the honeymoon period of cooperation will turn against each other if the interests are large enough. These possibilities exist. At that time, Song Wei will become Xia Rufei's weakest link, so he must arrange Song Wei in advance.

Taoyuan Island is undoubtedly the most secretive and safest place.

Originally, Xia Rufei wanted to build a communication system so that Song Wei could keep in touch with them even on the ground.

However, when he was in the United States, he consulted Elon Musk on the issue of communication between heaven and earth, and then he realized that it was difficult to achieve it, which required the support of a huge measurement and control network and countless communication equipment. Of course, when Xia Rufei and his team were still in the low-Earth orbit, theoretically, the content they wanted to publish on the ground can even be heard through ordinary radios. However, as the spacecraft enters the Earth-Moon transfer orbit, or even enters the moon, the signal will be very weak, and it can only be listened to and cannot achieve calls between the two sides, so it is not very meaningful.

What's more, this one-way release is theoretically something that everyone in the effective area can hear, provided that they know the frequency band of the communication, so there is no confidentiality at all, and it may even cause a sensation because of being monitored by some enthusiasts. At this stage, China does not have a manned space mission that is being carried out, and the voices of Chinese people suddenly came from space, which is really scary.

Therefore, after Xia Rufei understood the difficulty of the Tiandi call, he decisively gave up.

In this way, Song Wei has no need to stay in the capital.

After learning that Xia Rufei and the others would completely lose contact with the ground during their trip to the moon, Song Wei was still worried because Xia Rufei told her that she would keep in touch with her before, but after listening to Xia Rufei's explanation, Song Wei also expressed her understanding. After all, Xia Rufei could not increase so much workload specifically for this matter.

What's more, even if Xia Rufei wants to work hard to complete it, it is basically impossible.

The Chinese astronauts' conversations with the ground in the Tiangong experimental cabin were the result of the joint efforts of countless measurement and control stations, including the measurement and control ships that have been sailing on the ocean. Even if Xia Rufei has the ability to go all the way, he would not be able to build such a measurement and control network in a short time.

Of course, astronauts’ heaven and earth calls are very high-quality. They not only have sounds, but also images, and sound and picture synchronization is also very good. Not only that, astronauts in the Tiangong Experimental Cabin can also see the pictures uploaded on the ground and hear the sounds on the ground simultaneously. This is a real heaven and earth call, and it is a heaven and earth video call.

Through this period of time, Chen Nanfeng and others understood Xia Rufei better, and the vague mentality of being alert to each other was also greatly relieved.

So Xia Rufei and Song Wei went out alone, and Chen Nanfeng and others did not interfere, nor did they propose to send someone to follow.

Of course, Chen Nanfeng and the others were not worried that Xia Rufei would take this opportunity to directly drive the Obsidian Flying Boat to the Moon alone, because on the one hand, Xia Rufei has a large number of industries in the secular world and has a Zhaixing Sect that is closely related to him in the cultivation world. If Xia Rufei really dares to betray his faith, Chen Nanfeng and the others will definitely use thunder to deal with Zhaixing Sect; on the other hand, in order to avoid suspicion, Xia Rufei handed over all the outboard spacesuits and oxygen supply modules to Chen Xuan, Mu Jianfei and others for preservation. He only left the dragon spaceship. Without the spacesuits and oxygen supply modules, he naturally could not go directly to the Moon.

In this way, Xia Rufei took Song Wei and took a flight of obsidian flying boat around the Pacific Ocean for several circles. After confirming that no one was following him, he turned around and headed straight for Taoyuan Island.

In fact, with the speed of the Obsidian Flying Boat, at least a few circles, even if someone follows him, he will inevitably lose his direction, because with the current strength of the practitioners flying with swords, they cannot keep up with the speed of the Obsidian Flying Boat, and even Chen Nanfeng cannot do it.

Unless there is a hidden Nascent Soul master, the probability is very low.

After taking Song Wei to Taoyuan Island, Xia Rufei gave Luo Qingfeng, who was guarding Taoyuan Island, and Zheng Yongshou, some instructions, asked them to take good care of Song Wei, and at the same time, they should be alert at all times to ensure the safety of Taoyuan Island. Then he left some cultivation resources for Song Wei, so he hurriedly drove the Obsidian Flying Boat away from Taoyuan Island, and he didn't even have time to gather with the veterans of the guard.

After returning to the capital, Xia Rufei continued to be familiar with the spaceship operation manual and other information in Siheyuan and the cultivators of the three sects until he received a call from Li Yifu.

Li Yifu told him on the phone that Elon Musk had produced the remaining off-cabin spacesuits and oxygen supply modules and delivered them in full.

So Xia Ruofei immediately told Chen Nanfeng and others the news, and everyone was very excited.

After preparing for so long, the supplies and equipment needed for the final adventure were finally prepared.

Everyone decided to go to the United States overnight to retrieve the spacesuit and oxygen supply module.

This time, even Chen Nanfeng and others went there together, and everyone left the courtyard of Liuhai Hutong.

Xia Rufei gave Wu Qiang some instructions. After all, if everything goes well, he will soon follow the expedition team to the moon and may not return to the Siheyuan for a long time.

In addition, Xia Rufei also considered that so many people could not disappear out of thin air. After all, there were people guarding the front and back doors of the Siheyuan.

Therefore, after instructing Wu Qiang, Xia Rufei took the cultivators to leave directly from the front door of the Siheyuan.

However, they did not go far, and the alley was still very secluded at night. After they turned a corner, Xia Rufei directly took out the Obsidian Flying Boat. Everyone quickly jumped onto the Osidian Flying Boat. Soon, the Obsidian Flying Boat quickly rose to its height, like a meteor passing through the night sky of the capital and flew towards the other side of the ocean.
Chapter completed!
