Before contacting the Prometheus database, Leo was full of expectations for the contents of the database, and he hoped to find out the relationship between the location of this world and the Earth Federation universe from the navigation data in the database, but now after he took a cursory look at the information in the database, he was very disappointed because the information had been deleted a lot.

Judging from the composition of the data types in the database, when the Earth Federation people who transformed the Prometheus transferred the data of the Prometheus to the current intelligent core, the people who carried out these tasks took the initiative to delete all the voyage data, including the spaceship voyage records of the Earth Federation people, and the voyage records of the Prometheus.

Although Leo didn't know what was going on at that time, and asked the supervisor here to make such a decision, judging from the sequence of data and documents in the database, the technicians at that time did not have a detailed deletion list, but only found all the information related to the voyage through semi-intelligent methods such as analogy and retrieval, and deleted it indiscriminately, so there were a large number of contents that were mistakenly deleted in these materials.

For example, there is a primitive navigation data in these data, this original navigation data is the original data that will be loaded on each navigation device, the function of this data is not only used to test the operation of the spaceship navigator, but also has some spaceship engine operation, flight shield, space jump and other key functions of the original control code, this part of the data can be said to be the most important information in spaceship navigation.

However, such a crucial piece of raw data was also deleted, and later technicians had to rewrite a flawed set of low-level code to barely maintain control of some of the ship's main equipment by the master computer.

However, it was clear that the technician who wrote this code also knew how bad his code was, so he didn't let the intelligent core control too many things, only a few key equipment, such as the ship's engine above the entrance to the abyss.

This can be regarded as a crooked fight, saving Leo the time to write additional control code, and after leaving here, he can directly teach the part of the code in question that activates the ship's engine to the Lanxi City administrator.

Although the technicians at that time had deleted the voyage records as much as possible, it was obvious that the technicians in charge of this matter were not very experienced, and relied too much on the intelligent retrieval function, rather than according to their own ability to search and analyze, so that some information related to the voyage but not belonging to the voyage data was preserved, and one of the most useful information was a part of the voyage diary left by a navigator named Henry.

Because it is a diary, this information is classified into the daily documents, the search and analysis level is the lowest, although some of the diary because of the data related to the voyage was searched out and deleted, but there is still a large part of the content related to the voyage preserved, and these diaries can be preserved, the biggest reason is that the navigator who wrote the diary is a crappy poet, always likes to use some verses to describe what he saw and heard on the voyage.

Although the poems are of no literary and artistic value, they are straightforward enough for the reader to easily know what is being described, and through these descriptions, the time of each diary, and the speed of the ship itself, Leo is enough to analyze the ship's course from it.

From the point of view of the route, this spaceship in the period of the Earth Federation is a caravan spaceship, and the starting point of the spaceship route is Chang'an Star, the largest colony planet of the early Earth Federation, and the most famous scenery of this planet is the twelve hanging moons, because this planet has twelve satellites of different sizes, and every ten years or so, twelve satellites will appear in the night sky at the same time, and this scenery is also described in the navigator's diary.

Chang'an Star is not the earliest colony planet developed by the Earth Federation, but Chang'an Star is the best developed of all the developed colony planets, and the overall scale there has surpassed that of the mother planet.

In the early expansion plan of the Earth Federation, Chang'an Star is also the core of these plans, almost all of the activities related to the colony, including commerce, military, exploration, etc., all take Chang'an Star as the starting star, and at the end of the early development activities of the Earth Federation, the ruling center of the Earth Federation even moved to Chang'an Star, making Chang'an Star the capital planet of the Earth Federation.

This situation continued until the Earth Federation developed faster spaceships, contacted more advanced alien civilizations, knew the wider universe, and expanded the scope of the colonized planet to a farther galaxy, and the position of Chang'an Star also changed from the front to the rear, and its importance also decreased rapidly, and finally changed back to an ordinary hinterland colonial star.

It is not difficult to see from the words on the diary that when this spaceship set sail, Chang'an Star was still the core of the Earth Federation's colonial star, and it was mentioned in the diary that the Council of the Earth Federation had begun to propose to move the ruling center to Chang'an Star to facilitate the management of the colonial planet, which shows that the time had entered the end of the early colonial exploration period.

After that, the ship began to travel between the colonized planets along a golden route that was very famous in the early commercial history of the Earth Federation, and carried out various commercial activities.

This route can be regarded as the lifeblood of the Earth Federation at that time, almost more than 70% of the commercial tax revenue of the Earth Federation comes from this route, and almost all cross-galaxy commercial activities are related to this route, and people at that time also called this route the Caribbean route.

Because this route is similar to the colonial route of a certain ocean exploration period in the Old Earth era, there is a large number of commercial activities, and there are also a large number of pirates along with commercial activities.

This is also the reason why this golden route was still so famous during the time of the Earth Federation where Leo was located, because at that time, there were countless battles between interstellar pirates, caravans and Earth Federation fleets, and countless legendary stories continued to occur on that route, until later these legendary stories have become legends, and continue to circulate in various art forms in the star fields under the jurisdiction of the Earth Federation, and they have endured.

Although the later generations of the Earth Federation people longed for the era when those legendary stories took place, and regretted not being born in that magnificent era, for the people of that time, sailing on this route was definitely not a happy thing, and it became a daily routine to be afraid that a pirate fleet would suddenly emerge from some places, and even many people had to rely on drugs to relax themselves.

Reading between the lines of the navigator's diary reveals a fear and hatred of interstellar pirates, even if his caravan has ten frigates, it still does not make this navigator feel safe, and these interstellar pirates are one of the main reasons why the Earth Federal Government is preparing to relocate the ruling center to Chang'an.

However, the record of this golden route only occupies the general diary file, and after the ship arrived at a colonized planet, Noyes, the ship's course changed, and even the function of the entire fleet changed.

During the first great exploration of the Earth Federation, the merchant fleets of large corporations were not only engaged in commercial activities, but also sometimes served as expedition fleets, development fleets and other activities that could seek huge benefits for large corporations, and some large corporations would even make their own fleets make cameos as interstellar pirates to fight against rival fleets.

It is clear that the navigator's fleet is such a multi-functional fleet, and when their commercial mission is completed, it will be transformed into another functional fleet, such as the exploration fleet.

In the early history of the Earth Federation, Noyes is also a very famous planet with special significance, for example, the first contact with an alien civilization in the official sense of the Earth Federation was on this planet, and the first civilization treaty signed with an alien civilization was also on this planet, and for a long time, this planet was also the starting star of the Earth Federation's development fleet.

Although the navigator's diary does not specify the specific situation, from the contents of the subsequent diary, it is clear that the function of their fleet changed due to an unexpected event, which forced them to suspend their ongoing commercial mission and transform the entire fleet into an exploration fleet, launching an exploration mission towards the unknown star fields of the universe.

Moreover, it can be seen from a few words that this fleet was not the only one that changed its mission due to unexpected events, and almost all the fleets that were resting on Noyes Star at that time changed the nature of the fleet and headed for the depths of the universe.

Although there is only one sentence in the diary about the incident, and it is still a lame verse, Leo still finds clues in this verse, and finds the details of the event against the history of the Commonwealth.

The poem in the navigator's diary is about a vase full of flowers suddenly blooming in the night, and although this poem is very rubbish in poetry, the description of the phenomenon is very good, because this sudden incident is called the vase incident.

The cause of the incident was that several cosmic telescopes located in Noyes observed that about five light-years away from Noyes, a cosmic mass suddenly bloomed in the universe, and the shape of the energy mass was like a vase full of flowers.

If it's just a weird energy pattern, after all, there are various forms of energy in the universe, but while observing this spiritual energy, Noyes's scientists also captured an energy wave signal, this energy wave signal is the energy wave signal used by the Earth Federation to develop spacecraft in the early days, and the meaning of this energy wave signal is only one is to discover a colonizable planet.

Because the technology of the Earth Federation was not developed in the early days, this energy wave signal device was very large and could only be used once, so this energy wave signal would only be activated when it was determined that the planet could be colonized.

At that time, the people on the planet Noyes did not study why there were still early energy wave signals in use, and they paid more attention to the location of the energy wave signal, because that location was a blank area from the star field map of the Earth Federation.

According to the Earth Federation's Pioneer Act, before the Earth Federation fleet is stationed on the colonized planet, any resource exploitation of the planet by the Pioneer is effective, inherited, and belongs to the scope of private property.

So when the relevant news spread, all the spaceships capable of cross-space flight on the planet Noyes became Pioneer spaceships, heading towards the newly colonized planet, although judging from the energy wave signal, it is obviously impossible for them to become the first discoverer, but it is good to eat some soup behind the first discoverer, after all, there are still huge benefits contained in it.

After the administrative center of the Noyes planet transmitted the relevant news back to the Earth Federation, the Earth Federation decided to send a fleet to the colonized planet after discussion, but this back and forth, plus the time spent on discussing and forming a fleet, etc., five years have passed, and when the development ship of the Federation fleet arrived in Noyes, the energy wave signal has also disappeared.

After that, the Federation fleet went to the star field where the signal source was located according to the coordinates recorded by the Noyes star scientists, but after arriving, they found that there was nothing in that star field, the entire star field equivalent to fifty times the size of the solar system, there was nothing, let alone colonizing the planet, not even a meteorite or cosmic dust, and according to the data measured by various means, it was found that the energy activity of this star field was infinitely close to zero.

And those exploration ships that came to this star field five years earlier than the Federation fleet also disappeared, and until Leo's time period, this matter was still the biggest mystery in the history of the Earth Federation's exploration.

The scientists of the Earth Federation have made countless explanations for this, and in the end, it is believed that the most likely close to the answer is that the vase-shaped energy pattern started with two omega-level higher life forms fighting, and those fleets that went to the star field in advance were involved in the war of the higher life forms, and everything in that star field was destroyed together, so there was such a strange state of dead energy in that star field.

As for why those pioneer fleets did not avoid the battle of the higher life forms, and took the initiative to go up, it was because the Earth Federation knew very much about the psionic beings at that time, and they all called the psykers new humans or superpowers, and they did not know about the existence of omega-level advanced life forms.

It's just that this speculation was later denied, because through some connections, someone entrusted the people of the Supreme Council of the Higher Civilization in the universe to investigate the past combat data of the Omega-level higher life forms, and found that no Omega-level higher life forms had ever fought so close to the Earth Federation, a nascent cosmic civilization.

The distance of five light years is like an abyss for some civilizations, but it is only a few steps away for omega-level higher life forms, and the battle between two higher life forms at such a close distance will definitely have a devastating impact on the earth civilization, so there has never been an answer to the investigation of the vase incident, and now this answer is in front of Leo's eyes.
