Start with a blacksmith shop.

Just like how Old Mei will never understand why hundreds of thousands of paramilitary personnel appear in Kyushu before September. And these paramilitary personnel will gradually decrease within two to four weeks.

Therefore, foreigners simply cannot understand many things about Kyushu. They cannot comprehend the way Kyushu operates, which often leads them to misjudge Kyushu.

There has long been a theory that Kyushu is a civilization disguised as a country. It is not just a country, and it is because of this characteristic that Kyushu has experienced ups and downs over the years, but has never been destroyed.

The title of the Four Great Ancient Civilizations is not just a joke. Kyushu is the only ancient civilization still existing in the world today. The other three have long been crushed by the wheels of history and their whereabouts are unknown.

Kyushu's actions have left other countries somewhat bewildered, yet Kyushu has simply gone ahead and done just that!

The contribution of the ten Sun Stars greatly alleviated the immense anxiety among the people of Kyushu, which can be considered a special contribution made by Li Zhenhua for the greater prosperity of Kyushu.

As time passed, Kyushu's energy problem was solved, and in space beyond Earth, spaceplanes had been continuously observing nuclear explosions for a long time.

Today, the scenes caused by the nuclear explosion are finally disappearing completely. Apart from the nuclear radiation that remains in the original location, all other external manifestations have vanished.

It's time for Snowy Owl and his crew to return to Earth. The spaceplane is no longer 8,000 kilometers away from Earth, because Earth is constantly revolving around the sun, while the spaceplane remains stationary at the site of the nuclear explosion for observation.

After making contact with the ground, the snowy owl received permission to return without any major issues.

The seven people aboard the spaceplane were overjoyed, genuinely happy, considering they had just completed two consecutive long-duration missions.

Before this trip to space, Snowy Owl and his crew had already spent a month in the air above Broken Bowl. After only a week of rest, they went into space again and stayed there for more than three weeks.

They were genuinely exhausted, so their smiles never faded after they received permission to return to Earth! The two reporters who came aboard the spaceplane were also quite eager to get back to Earth.

It turns out that spending long periods of time in space is also a kind of torment. The two reporters suddenly understood why submariners behaved that way after surfacing.

The spaceplane received clearance to return, and Snowy Owl and his crew immediately packed up. Once they finished up what they had to do in space, they were ready to head home.

Under the control of the snowy owl, the spaceplane slowly turned around and then, supported by its energy shield, headed straight towards Earth.

The Earth revolves around the sun every day, and they are now far away from it, having traveled more than 8,000 kilometers. The straight-line distance between the airplane and the Earth is now more than 900,000 kilometers, which is farther than the Earth and the Moon traveling back and forth in a short time.

And it's important to know that the Earth's revolution around the sun is ongoing; that is, while they are flying towards the Earth, the Earth is still moving forward.

Given such a long distance, after a series of calculations, even with the spaceplanes flying at their maximum speed, it would take them a total of 26 hours to catch up with Earth.

Don't be fooled by the fact that the distance between Earth and a spaceplane is very short in space; in reality, the distance is extremely vast. Ignoring the scale is just a charade!

Once the spaceplane was ready, it began its 26-hour journey to Earth, which was also the farthest the Snowy Owls had ever come from Earth.

Two weeks have passed since he gave Wang Yuesheng the backdoor program for the Sun Star. After giving him the control program, he didn't pay much attention to what had happened recently. Instead, he was focused on getting the space fighter out as soon as possible.

This is his most important goal for the next stage. As for other things, they are all trivial matters, and he will ignore them if he can avoid paying attention to them.

He wants to finish the spaceplane project as soon as possible, then go home to rest and spend time with his wife and children.

To be honest, he felt he owed his wife and children a lot. He often isolated himself because of his research and development tasks, but Li Yun never complained. Of course, she would still be unhappy when she felt like it.

He felt even more guilty towards his daughter, as he didn't have much time to play with her. So, after he finished dealing with the space fighter, he needed to take a good rest.

He now longs to be like an ordinary person, spending his evenings with his wife and children taking walks in parks and other public places. But such a life is a luxury for him right now, and suddenly he feels that he is living a really tiring life.

Recently, Li Zhenhua has also been optimizing how to use high-precision machining centers to manufacture various parts of the spaceplane. He has also simplified some of the previously complicated operating procedures.

He believed that once the space fighter was fully assembled, all its manufacturing data would be optimized and streamlined.

While he was still busy, the spaceplane that was taking pictures in space finally approached Earth's orbit. After they reduced the output power of the anti-gravity engine, they also arrived in Earth's orbit. Subsequently, the spaceplane was captured by Earth's gravity.

The seven people on the spaceplane were approaching Earth again for the first time in more than twenty days. The long space mission made them feel like they were wandering in the universe.

At an altitude of 400 kilometers above the Earth, Snowy Owl and his team took a short rest before, under the guidance of the ground control center, they landed their spaceplane at the Jiuquan base.

When the spaceplane flew toward Earth, other countries on Earth had already monitored it. Everyone was watching this event, wanting to see just how powerful Kyushu's spaceplane was.

The Kyushu spaceplane was only a dozen kilometers away from the giant mushroom bomb with a yield of tens of millions of tons. The explosive power of such a bomb was unimaginable. If the Kyushu spaceplane could return unscathed under such circumstances, then from then on, Kyushu would truly be the number one spaceplane on Earth without any controversy.

All countries' satellites in the sky were constantly monitoring the spaceplane's movements, and when they used all their observation methods and observed the spaceplane's top speed, all countries were dumbfounded.

Previously, when Kyushu used a spaceplane to travel between Earth and the Moon, the level of attention was obviously not as high as it is this time, so they had not been able to observe the speed of the spaceplane. But this time, they were able to observe it clearly.

That speed directly exceeds the third cosmic velocity, making it easy for a spaceplane to escape the sun's gravity.

If the spaceplane had always flown back at top speed, it would probably have taken about six hours. But in reality, it took 26 hours because there were acceleration and deceleration periods.

Even the United States is now rethinking its attitude towards Kyushu. The previous policy of blockade and restriction is no longer feasible. With such powerful strategic equipment in Kyushu, who would dare to blockade it?

We don't want to end up being counter-blockaded by Kyushu instead of sealing it off like we did with the broken bowl last time. Last time, they truly saw the strategic importance of the spaceplane, and this live broadcast of the nuclear explosion has shown them the defensive capabilities of the spaceplane.

Unbreakable and unrunnable, this unreasonable plane makes it impossible for others to compete. Therefore, even the United States is considering how to pay homage to the world's leader!

The spaceplane pierced through the atmosphere and finally landed at its designated spot at the Jiuquan base. This landing was broadcast live to the entire world.

As Snow Owl and the other six stepped out of the spaceplane, the vast majority of people in Kyushu cheered. Such a grand event was something they probably only witnessed once in their lifetime.

When they returned safely, the vast majority of them had long faces. Of course, these people were scattered all over Kyushu, and Xiao Rizi was the one who felt the hardest.

In recent years, as the US has been loosening its grip, the US has gradually become much stronger militarily. No one knows if they have the heart to restore the glory of their ancestors.

But once their ambitions were aroused, even if they received a devastating blow, with the neighboring Kyushu being so powerful, they didn't even dare to launch a sneak attack.

If this thing angers Kyushu, they'll do whatever it takes to take them down, especially since Kyushu has spaceplanes to back them up; taking them down would be a piece of cake!

So as the warriors in Kyushu gradually developed their own strength, the other countries became incredibly docile and cowardly, except for those like Broken Bowl who weren't very bright.

Those with confidence, like Lao Mei, were not living a carefree life, but they were still acting cautiously because they had discovered that Kyushu's spaceplanes were too destructive.

Even if the broken bowl was no good, it was still a member of the Europa Union and a member who broke the contract. But just one week of blockade in Kyushu caused chaos in the fruit box.

Furthermore, according to the calculations of the Lao Mei think tank, without any major changes, it would take at least five years for the broken bowl to recover its original form, and that is in the ideal state assuming no internal rebellion has formed.

After Snow Owl and the others returned to Earth, their superiors, taking into account their actual situation, gave them a long vacation so they could rest and recharge.

Furthermore, since the advent of spaceplanes, major satellite companies in Kyushu have been accelerating their manufacturing efforts, so satellites that were intended to be launched into space were frequently taken into space by spaceplanes.

While launching a spaceplane into space isn't entirely costless, it's negligible compared to the cost of a launch vehicle. This has spurred the Kyushu Space Agency to aggressively use spaceplanes to launch satellites.

By this time, most of the space debris in Earth's orbit had already been cleared away.

The advent of spaceplanes can be said to have given the space environment around Earth a major cleanup, with a huge impact.

The spaceplane continued to be useful in the days that followed, and Li Zhenhua continued his efforts.

When everything calmed down, for some reason, the weather in Kyushu became problematic again in recent years. In Shennongjia, northern Hubei, wildfires broke out due to excessive dryness caused by the weather.

How should one extinguish a wildfire in the deep mountains? The best way is still to bring rain. As long as a large amount of water falls, the fire is easy to extinguish.

However, the cause of the fire was still the weather, so hoping for rain was wishful thinking. But the best method should still be used. Since there was no rain from heaven, then artificial rain should be used.

If there is little water vapor in the clouds, then use helicopters to divert water and carry out artificial precipitation.

This task fell to the Twinblade helicopter. After a long period of production by Changhe Aircraft Manufacturing Plant, a total of 96 helicopters have been built throughout Kyushu. Almost all of the helicopters have been assigned to units similar to the Spring City Eagles.

Used as an assault force, all the Double-Edged Swords immediately assembled after receiving the order to deploy helicopters to fight the fire.

After the assembly, all the weapons and equipment on the plane were unloaded and replaced with various supplies.

Emergency water tanks converted from shipping containers were also urgently transported over. Then, two helicopters worked together to lift one water tank, totaling thirty cubic meters of water. The helicopters carried the tanks from the lakeside near the fire to the airspace above the fire, and then poured the thirty cubic meters of water over the fire from the air.

When the Twinblade helicopters arrived, the fire was brought under control. The soldiers who were working hard to rescue people on the mountain felt an overwhelming sense of hope when they saw the water falling from the sky.

A total of 96 double-bladed helicopters were deployed, making fewer than 600 sorties, and lifting a total of more than 14,000 cubic meters of water.

Although it may not seem like much, it played a significant role in extinguishing the fire.

This fire, which could hardly be considered an interlude, still didn't affect Li Zhenhua, who was busy building the aircraft. Moreover, he didn't know where a sense of urgency would arise while he was building this aerospace fighter.

It seemed that as long as the aerospace fighter was completed, the urgency could be stabilized, so he couldn't help but speed up the manufacturing process.

Time passed slowly, and the space fighter was gradually born in his hands. To date, he has completed the manufacturing of all the parts of the space fighter.

All that's left is assembly. Although entering the assembly stage might seem like the end, for the aircraft, it's actually just the beginning.

Leaving aside airplanes and focusing solely on cars, the efficiency a car can achieve with good assembly is worlds apart from that with bad assembly.

Therefore, his task ahead remains very challenging, because he not only has to assemble the fighter jets, but he also has to continue his own assembly work and research how to develop an assembly process while ensuring accuracy.

Once he masters the assembly process, he won't need to worry about the manufacturing of the space fighter anymore.

As long as you strictly follow all the instruction manuals he wrote, you will definitely be able to build a high-performance aerospace fighter!
