Start with a blacksmith shop.

How long would it take to fly over a distance of 5500 million kilometers?

Even if we calculate based on the third cosmic velocity that current spaceplanes can reach, which is 16.7 km/s, it would take 3293413 seconds, 54890 minutes, 914 hours, or 38 days. This does not include acceleration time or deceleration time when reaching the vicinity of Mars.

If we add these things, it will take at least 100 days to travel back and forth. Once they get up there, they won't have anywhere to replenish their supplies. So, for safety's sake, we brought them enough supplies.

If you ask what they brought the most with them, it would definitely be enough water. Although there was a lot of water, the five of them still had to use it very sparingly, and they even installed a water recycling and purification system on the plane.

With this system, for the time being, it's enough for five people to use it sparingly for three years, and those three years should be enough for them to return from Mars.

The cockpit of the spaceplane was also fully utilized. Because of Li Zhenhua's subsequent research on the Super Dragon modification, the avionics system had been completely upgraded. Originally, it would have required five people to work together to fully utilize the aircraft's performance.

After the upgrade, it no longer requires five people, but only three people are needed to drive it. Therefore, the six driver's seats in the cockpit were rearranged.

Three of the seats are just seats, while the other three still have driving functions. The only thing that hasn't been changed is the design of the escape pod.

In addition to the six-person driver's seat, a simple gym was also set up in the cockpit, while the cargo hold served as the living area for the five of them, and the interior was decorated like an apartment.

It also has a top-of-the-line sound system with all the latest popular songs and other entertainment. To keep the five astronauts from getting too bored in space, they can sing karaoke, play games, watch TV series, and watch movies.

These entertainment files alone filled 20 massive 2TB hard drives. Don't think these things are superfluous; they are absolutely necessary, even though their journey to Mars won't be long—estimated to take at most fifty days.

However, in the space environment, there were only five of them, and no one else. Humans are social animals, and people who are separated from their group for too long are bound to develop mental health issues.

Just like submariners, they are also prone to psychological problems when carrying out diving missions. To avoid such problems, these recreational facilities are necessary.

Actually, this is because current communication methods are not advanced enough. If Kyushu could develop quantum communication now, allowing spaceplanes flying away from Earth to contact Earth, then none of this would be a problem. But we just haven't mastered this technology yet!

After countless calculations by experts, the interior design plans for the spacecraft were finally finalized, and construction began immediately after the plans were finalized.

Kyushu has never disclosed the plan to go to Mars to the outside world; everything has been carried out in secret.

The reason why it wasn't revealed to the public was because they were afraid that others would know that Kyushu only had one Super Raptor, and that the countries in between that Kyushu had suppressed might take this opportunity to cause trouble.

That's why such tight secrecy was maintained; apart from the participants in the plan, only a few bigwigs at the top knew about it.

After a period of weakness, Kyushu suddenly embarked on a journey of exploration beyond the Earth, and the time span between these two periods was only a few years, which is actually quite a large span.

Kyushu did not intend to keep this secret for long. After all, many countries could monitor things in space. If the spaceplane disappeared for a long time, combined with their previous intelligence, they could roughly deduce that the spaceplane was no longer near Earth.

The interior of the spaceplane is undergoing intensive renovations, and the Kyushu Space Agency, after a series of discussions, has finalized its plans to send astronauts to Mars.

There was a small hiccup when the personnel were being finalized. A senior figure suggested that it might be necessary to have a space scientist accompany them on the trip.

This proposal immediately opened people's minds, as if a scientist going into space could at least put their understanding of space to good use.

Ultimately, the bigwigs made up their minds that now was not a good time to send scientists up.

It's not too late for scientists to go when the technology is truly mature. For now, the personnel going up should mainly be astronauts, and they should be in particularly good physical condition.

Even with Wu Gang's spacesuit, a good physique is still extremely useful.

In this mission to Mars, Snow Owl and his group of five were the best choice, but they couldn't all be sent out at once. So one of them was selected to stay on Earth and act as the leader of the team piloting the Super Raptor.

The Kyushu Space Agency's plan proceeded exceptionally smoothly, while the designers and manufacturers of the spaceplane were completely unaware of the plan.

At this time, Li Zhenhua was still working on creating the perfect mode of transportation for his travel plans.

The Iveco, the most commonly used vehicle he developed for this trip, has already begun manufacturing at the factory in Qingdao in cooperation with Changzi Motors.

Once this car is completed, it will be able to solve most of the problems for the family of three's trip, perfectly covering almost everything from clothing and food to accommodation and transportation.

After all the designs for this bus were completed, he began the redesign of the interior of the Green Ox Bus, and the bus was manufactured without the help of anyone else.

Instead, Li Zhenhua received feedback from the Kyushu Guard Regiment that the bus would be manufactured by experienced guards in Kyushu.

All of this was because the guard regiment made the decision considering the safety of the aforementioned bigwigs.

Once the manufacturing problem of the Green Bull Bus was solved, he began to study how he and Li Yun could disguise themselves.

Initially, Li Zhenhua's research on camouflage was intended to use physical methods, but after much thought, he felt that this method was too cumbersome.

Whether they use silicone masks or makeup techniques, one of the four great evil arts of Asia, it is all extremely time-consuming, and the disguised image is also very fixed, which is not conducive to their disguise when traveling.

Ultimately, the chosen approach was to use technology to solve the problem. After much deliberation, Li Zhenhua finally set his sights on facial holographic projection camouflage technology.

If this technology can be mastered, its future application prospects are quite promising. Although it is unlikely to be used in civilian applications, it would be a remarkable technology even for military use.

For example, if he really develops holographic projection technology, then by using this technology to amplify the output device and expand its coverage area, it would be entirely possible to use this technology to achieve the visualization and stealth capabilities of stealth fighters.

Previously, stealth referred to concealing one's form on radar. However, this new technology allows fighter jets to disappear from sight, becoming invisible to the naked eye.

If he manages to develop this technology, it will be a win-win situation, not only providing convenience for his trip but also having broad application prospects in the future.

He then began to tackle this technology. Although it was extremely difficult, he was determined to do his best to complete it, no matter how difficult it was, so that he could take his wife and children to travel around the vast and beautiful landscapes of Kyushu.

The virtual lab remains his greatest asset; the amount of time he spends researching a topic within it is his biggest weakness.

The technology he wants to research is not limited to this one; he also wants to develop a portable particle energy shield. The purpose of the disguise is simply to prevent others from recognizing them when they are playing, so as to avoid unnecessary trouble.

The particle energy shield that can be installed on the vehicle is the real guarantee of safety. The existence of the energy shield can enhance their protection to a higher level, and it also helps them to escape without worrying about bullets or shells threatening the vehicle from behind.

His inspiration for researching portable particle energy shields came from the nuclear power bank that was revealed to the outside world when the 003 was launched. Since aircraft carriers can use nuclear power banks, he can research something similar himself.

In essence, they are the same thing, except that one stores electricity and the other stores golden crow particles.

He was extremely familiar with the solar energy core, golden crow particles, and Dijun engine that he had created, and he understood all the principles behind them.

If we can develop something that can store Golden Crow particles for a long time, and a simplified version of the Emperor Jun particle engine, and make the two work together, then the idea of ​​a particle energy shield will definitely succeed.

He then began to study in depth how to store the Golden Crow particles, and he thoroughly researched the subject.

Once the method for confining the Golden Crow particles is thoroughly studied, all subsequent problems will be easily solved.

He delved into the virtual laboratory to study the two key technologies, while a team of twenty people in Beiping was on a train heading to Dongshan.

These people were the soldiers of the Kyushu Guard Regiment, the same group of soldiers who assisted Li Zhenhua in building the Blue Ox Bus when they were in Kyushu.

They were extremely familiar with the Blue Bull Bus; the Blue Bull Buses currently used by the big shots were made by these soldiers.

The soldiers traveled by high-speed rail from Beiping to Bajishi, and then, under the arrangement of the local People's Armed Forces Department, were sent from Bajishi to the hometown of calligraphy and painting.

These warriors were extremely familiar with the mythical beasts of the Nine Provinces and also with Li Zhenhua's workshop. Their arrival accelerated Li Zhenhua's redesign of the Green Ox Bus.

First of all, Li Zhenhua reduced the weapon system on the Qingniu Bus, and used the space saved by the reduction to house Xiao Lizi's car.

In his vision, this little car would be equivalent to an emergency escape pod. If things got out of control, ensuring Little Chestnut's safety would be enough.

That possibility is absolutely impossible, but it's better to be safe than sorry.

After the soldiers arrived, Li Zhenhua immediately distributed the work instructions for all the bus modification plans, and then Li Zhenhua's private workshop became busy once again.

Everything was proceeding smoothly, and if you had to pick the most impatient person during this time, it would definitely be Li Yun.

Especially after Li Zhenhua built Xiao Lizi's little car, Li Yun was absolutely fed up with him.

Because recently, Xiao Lizi has wanted to spend all her time in her little car, and she is extremely fond of the little car that Li Zhenhua made for her by hand.

She needs to drive around in a car for a long time every day, but she can't do it herself, so she has to ask an adult to drive for her while she sits.

This added a lot of work for Li Yun. Every day, Xiao Li Zi would pester Li Yun to drive the little car and take her out for a long walk.

Li Zhenhua, who caused all of this, was someone Li Yun remembered. For every hour Li Yun pestered him to control the remote, she would leave the car in automatic mode for that entire night.

Occasionally, Li Yun would also try manual labor. Self-reliance is the key to success, and it makes perfect sense no matter where you are.

Both Li Zhenhua and Jiuzhou are working hard towards their plans.

During this period, the old man Wang Yuesheng had been keeping a close eye on the assembly work of the Super Raptor. After the assembly work was on track, he left Dongshan.

As for where he went? He went directly to the Lop Nur nuclear test site. As for his purpose in coming here?

The reason he came here was entirely because of the solar energy core.

Currently, all of Kyushu has only ten brand-new solar stars and one that is about to be scrapped. Even if the scrapped one is refueled with helium-3, the total number will only be eleven. Moreover, after the Mars program begins, there will be one less core.

Therefore, under the current circumstances, the only way to ensure that Kyushu has enough energy cores for its subsequent plans is to start production of solar energy cores.

Among the applications of the solar energy core, the biggest plan of the Kyushu upper class is to cover all of Kyushu's existing territory and territorial waters with energy shields.

Normally, this energy shield that can cover the entire country may not be needed, but Kyushu cannot be without it. Only when this protective shield is truly deployed throughout Kyushu, and Kyushu's safety is no longer an issue, will Kyushu truly have the confidence to face challenges from other countries around the world.

If things really come to a head, with all of Kyushu protected, Kyushu will be in an absolutely invincible position.
