"Mo-Star class" U3-173 combat spacecraft travels through the stars, gradually moving away from the outer planetary orbit of the Cygnus constellation and entering the inner star system, heading towards the number one planet of the Cygnus constellation. During the spacecraft"s journey, its shield continuously absorbs energy to resist the radiation and high temperatures of the two stars in the Cygnus constellation.

In the conference room at the stern of the battle cruiser, Samuel White and the chief military officers on board were holding a meeting, three of whom were women. More than 5,000 years after the founding of the Star Federation, women are no longer limited by childbirth and have demonstrated superior intelligence and potential compared to men. Women not only hold important positions in the military, but also occupy important positions in politics and scientific research.

Thanks to the significant development of genetic factors and metamorphosis, humans with ugly appearance and unhealthy physique have almost disappeared in the universe, and humans no longer have problems with aging and disease. In the case of similar appearance, the standard for judging human excellence has shifted from external image to internal temperament.

The female military officers on board the battle cruiser are all naturally beautiful and have excellent temperament, representing that their souls possess wisdom far beyond ordinary people.

At the beginning of the meeting, Major Emily Johnson, the data supervisor, raised a question: "I have reviewed all the information about the Star Federation"s spacecraft, but I have not found any information about Explorer One. From the received raw data, it should be a rudimentary spacecraft built ten thousand years ago when humans were trapped in the solar system. How could this spacecraft, which cannot traverse antimatter space, reach a distance of 1,500 light-years from the solar system?"

Colonel John Smith, the head of the ground forces, also spoke up: "I need all the information about Explorer One, otherwise the work of excavation or search will be greatly hindered."

Colonel John Smith paused for a moment and continued, "Based on spectral and radiation analysis, Planet One is highly likely to be completely destroyed in the next rotation cycle because the star in the Cygnus constellation is brewing stronger core fusion, and the energy released is enough to destroy Planet One. Therefore, we have less than seven Earth days to complete the search and transportation tasks, and any mistakes are intolerable."

Major General Samuel White supported his chin with the back of his hand and looked at the other chief military officers at the conference table, slowly saying, "The Star Federation only recently learned of the existence of Explorer One, which was after the Zeta Star Campaign."

This tale has been unlawfully lifted from Royal Road. If you spot it on Amazon, please report it.

When Major General Samuel White mentioned the Zeta Star Campaign, every attending chief military officer showed a listening expression.

The Zeta Star System is located 39 light-years away from Earth, the mother planet of the Star Federation, while the Cygnus Star System is 1500 light-years away from Earth. Even the most advanced spacecraft of the Star Federation would take 12 Earth months to reach there in antimatter space.

Like the Cygnus Star System, the Zeta Star System is also a binary star system. Among the thirteen planets in the Zeta Star System, the third, fourth, and fifth planets are terrestrial planets suitable for human habitation. When humans sent a spacecraft to the fourth planet in the Zeta Star System, they discovered ancient and strange buildings covering the surface of this unfamiliar planet. These buildings appeared to have a long history, covered with thick dust, and many places were already damaged. The design of these buildings looked very peculiar, with no straight lines or angles, all flowing and strange curves, giving people an irregular and rhythmic beauty.

Judging from the size of the doors, windows, and stairs of the buildings, the designers of these extraterrestrial buildings were only 1 to 1.2 meters tall, apparently the home of the legendary "little gray men." However, when humans arrived, these buildings were already empty. The little gray men had long left this planet, leaving only these amazing buildings as the only legacy on this planet.

After nearly a century of immigration efforts by the Star Federation, humans have redeveloped high-tech civilization on the fourth planet in the Zeta Star System. Until one day, an unknown alien fleet suddenly appeared on the orbital space station of the fourth planet in the Zeta Star System. Since then, communication between the fourth planet in the Zeta Star System and the government of the Star Federation has been completely cut off.

The loss of contact with the fourth planet in the Zeta Star System has caused panic in the Star Federation, which has long lived in peace and prosperity. The Star Federation has sent an unprecedented large-scale armed fleet to explore the Zeta Star System. Battles broke out in outer space of the Zeta Star System, and almost all of the Star Federation"s expeditionary forces were destroyed, bringing heavy blows and enormous fear to the Star Federation."

The battle twenty years ago made every officer present feel as urgent and profound as yesterday!

What puzzled the Star Federation even more was that these alien spacecraft and appearances showed that they were also human! The Star Federation had no idea where these ferocious humans came from.

Major General Samuel White continued, "As you all know, the DNA sequencing of captured prisoners shows that the enemy occupying the Zeta Star System is also human like us. Therefore, the Star Federation Research Institute was ordered to thoroughly investigate all historical records, including the oldest documents excavated in archaeology, to see if humans immigrated to other planets before the establishment of the Star Federation."

After a slight pause, Major General Samuel White said, "Finally, we found some clues."

Colonel Sophia Rodriguez, the head of the Navigation Department, looked suddenly enlightened and said, "Is it Explorer One?"

Major General Samuel White nodded seriously and revealed shocking news to all attending chief military officers, “Not only Explorer One, but also Explorer Two."
