This was a planet that was in the same parallel world as Earth. On this planet, seawater covered 71% of the surface.
Humans were born, grew, nurtured, and developed their own civilization in this blue land. They developed weapons of war similar to those of humans on Earth and began to compete for land and sea resources.
Warplanes soared in the sky, warships galloped on the sea, and in the process of competing for resources, human countries created a large number of advanced weapons and equipment. Of course, they were the same as the humans on Earth. They had many political powers and countries.
After a round of intense technological and military competition, Donghuang, White Eagle, Imperial, Zhongying, Iron Blood, Northern Alliance, and Free Iris achieved technological breakthroughs. In their state-level secret research laboratory, they developed the ultimate strategic weapon that could control the sea, land, and air-the Sky Fortress.
The theory of the Sky Fortress was first proposed by a White Eagle scientist, Albert Grox. He installed the newly developed XBO-X engine on an aircraft carrier, giving it the ability to maintain a speed of 40 knots in the sky.
After a series of modifications, the first Sky Fortress on Earth was born. She had just left the factory and had four XBO-X engines. She could maintain a cruising speed of 45 knots in the water and a flying speed of about 40 knots in the air. The armor was made of the most advanced titanium alloy material, with an average thickness of 500mm. It was equipped with 300 air-to-air missiles, 16 long-range conventional missiles, 2 Shiva nuclear missiles, 60 White Eagle F-55 fighter jets, and 16 B-5 strategic bomber aircraft. The exterior was equipped with eight new twin 127mm anti-aircraft guns, three triple 410mm magnetic rail accelerator guns, and 40 eight 40mm anti-aircraft guns. With such powerful firepower, after two days of long-distance sailing, she successfully launched a sneak attack on the Northern Alliance's oil base in the Bering Strait.
In this battle, the Sky Fortress did not have any escort teams. With his extraordinary ability and excellent command, he completely destroyed the Northern United Third Fleet, which included 4 aircraft carriers, 8 heavy cruisers, 14 light cruisers, 22 expulsion ships, and 300 aircraft, while only revealing 50% of his strength.
In less than a day, the whole world was shocked by this new weapon. All countries withdrew their coastal defense lines and began to secretly invest in the research of this new weapon.
Three years later, the Predator announced that its first Sky Fortress had been completed. Under the escort of the First Fleet, it headed to the waters near the Arctic Ocean for its first experiment. Not long after, Zhongying, the Royal Family, the Northern Alliance, and the Free Iris also announced that their first Sky Fortress had been completed and would be in service within three months.
A year later, Donghuang revealed four Sky Fortresses at once. They were named after Prosperity, Humanity, Civilization, and Harmony. The four Sky Fortresses appeared at the National Day military parade, making Donghuang the country with the most Sky Fortresses in the world.
Before the crisis, there were seven countries that had Sky Fortresses. These seven countries were the Big Seven that was respected by all the countries.
With the advancement of human technology, various countries were frantically exploiting natural resources to further develop the Sky Fortress. This destructive exploitation finally attracted an unknown enemy.
The enemies first appeared in the middle of the Pacific Ocean. They were a group of gray girls without emotions, colors, and language. They had a body that was not afraid of nuclear bombs, and they summoned almost insane warships to directly destroy the White Eagle's Pearl Harbor base in the Pacific Ocean. The White Eagle had sent out a batch of elite ships to reinforce them, but the final result was that they were all wiped out.
Humans often tried to communicate with them, but the result was only a rustling sound.
This group of girls effortlessly occupied the central Pacific Ocean, and then in just a month, they controlled 90% of the world's sea area. The Big Seven could only use the Sky Fortress in their hands to deal with them in the coastal waters.
As the ocean was occupied by this unknown group of enemies, humans had lost a large portion of their resource extraction points. In just a few years of struggle, humans began to experience a shortage of resources. This phenomenon led to humans finally giving up on fighting each other and focusing on this group of invaders from the other world named [Sirens].
After that, in another joint operation, the humans gathered all the sky fortresses and launched the largest counterattack against the Siren. In this operation codenamed " Thorny Rose ", the humans had successfully destroyed a batch of small-scale Siren ships and two low-level Siren girls at the cost of three Sky Fortresses and five Sky Fortresses. They had also discovered a golden cube in the wreckage of one of the girls.
Subsequently, the Human Consortium launched a project called [Azure Sea Route], which gathered famous scientists from all over the world to study this cube. After all, this cube was the first trophy that humans had seized from the Siren. Humans hoped to find a feasible way to deal with the Siren from this cube.
However, after nearly a year of exploration, scientists still did not understand the function of this cube. In the past year, the humans had not found any new golden cubes.
Therefore, humans believed that this cube might just be an ornament of the Siren and had no practical use. In contrast, some of the strange metals found in the Siren's wreckage had superior values than any existing armor of mankind after extraction. After this discovery, humans began to gradually reduce the funding for the Azure Sea Route until the Azure Sea Route project finally stopped operating.
The golden cube from [Siren] was finally placed in the vault of the Swiss bank by humans. Humans began to use the metal from [Siren] to develop a more advanced sky fortress to fight against the Siren.
However, something unexpected happened. A new round of [Siren] attacks allowed humans to see the original [Siren] they had seen for the first time. She used a telepathic electric wave to paralyze all the sky fortresses made of Siren metal and turned them into new Sirens.
The human commander had eaten a whale! Faced with such a situation, the humans returned to their original state overnight. They could only rely on the first dozen Sky Fortresses that did not use Siren metal to survive.
At this moment, a series of urgent knocks came from the vault of the Swiss bank. The staff opened the door curiously and found that there were 600 gold bricks missing from the vault! Then, a petite green-haired, cat-eared girl lay by the door, trembling.
The girl called herself Akashi and was a creature called Ship Girl. They had been summoned to save the people from danger.
Through communication with Akashi, humans had a preliminary understanding of what Siren and Ship Girl were, and they knew the correct way to defeat Siren. As a result, the long-idle Azure Sea Route project was put on the agenda again.
Central Pacific Ocean, Hawaiian Islands.
Three young girls who were almost the same size as humans, but with slightly gray skin, sat on the dock. They were communicating in human language.
"Sister, that experimental subject has finally awakened. I didn't expect humans to have such low intelligence. We only found a way to activate the experimental subject now.”The curly-haired loli, who was the smallest among the girls, threw a stone into the distant ocean and said in a childish voice.
One of the older sisters, who was dressed in a kimono and looked like a super righteous person from the European faction, patted her head and said with a smile,"How can you say that? Little sister. Humans were the most perfect creatures created by the Pioneers back then. It was only because they offended the Pioneer for some reason that their genes were degraded by the Pioneer. We, the noble Sirens, were forced by the Pioneers to transform into humans. Don't you understand why?”
"Don't the Pioneers like Second Sister's beautiful figure? Every time I return to the Holy City, Second Sister will be kept by the Pioneers for a few days before returning. Don't think that I don't know what happened.”The curly-haired loli pouted.
"Ho, ho, ho, little sister really knows how to joke. Isn't there a Pioneer who likes to play with you?" The kimono lady smiled charmingly at the curly-haired loli.
"Ah!" "Bad Second Sister, how can you say such a thing in front of Big Sister?!" The curly-haired loli cried out in surprise. Actually, the Pioneer didn't look for me for anything, it's just... It's just that…"
"But what? Tell me quickly, little sister." The kimono lady smiled as if her scheme had succeeded."Did you do something shameful with the Pioneer?”
Looking at the curly-haired loli's face that was about to turn from gray to red, the uniformed girl who could not stand it anymore finally spoke up,"Alright, Second Sister, don't say anymore. If this little sister gets angry and destroys the entire human Sky Fortress, our mission will be impossible to complete. I'm going back to the Holy City now. Get the chess player to send a few more experimental subjects to the humans first. Otherwise, I'm worried that the next wave of attacks will destroy the dozen or so broken ships.”
"Alright, Big Sister." The kimono lady smiled charmingly and said,"" You're in such a hurry to return to the Sacred City. Is the general going to 'talk' to you again?”
"I'm warning you! Read less of Zhongying's scripts in the future!”After the uniformed girl finished speaking, she disappeared into the vast sea.
