One of the most advantageous things for Earth civilization is that the interstellar wormhole passage connecting this colonial galaxy is very close to the current base camp of Earth civilization, which is in the depths of the meteorite belt less than a hundred light-years outside the meteorite sea civilization circle.

In order to hide this cross-galaxy wormhole passage as much as possible, the ancient civilization carried out the most thorough destruction of the interstellar environment around this wormhole passage, which led to the fact that although this cross-galaxy wormhole passage is very close to the meteorite star sea civilization circle, its condition is extremely dangerous, not to mention countless meteorite stars of all sizes, not to mention, there is also an extremely complex and dangerous space environment, what space rifts, space holes, and various cosmic disasters with high danger can be described as endless.

It is also because the environment here is so harsh, so although it is located not far from the periphery of the meteorite Star Sea Civilization Circle, it has not been developed for many years, and all the exploration ships that do not know the truth dare to go deep into this area, often have been destroyed by the endless cosmic dangers before they can go deep into the vicinity of the cross-galaxy wormhole passage.

Even if such a harsh environment has a buffer of millions of years, until now it is still a dangerous area that cannot be set foot in for those civilizations that are relatively lacking in scientific and technological strength, and no civilization in the meteorite star sea civilization circle has been able to escape any benefits in this area for millions of years, so for many local civilizations in the meteorite star sea civilization circle, this is a natural death forbidden area.

Even if the earth civilization has unified the meteorite star sea civilization circle, unified many local interstellar civilizations to vigorously develop, vigorously developed the meteorite star sea around the meteorite star sea civilization circle, hollowed out countless meteorite star smelting, and purified various industrial development materials, but this dangerous star field has never been disturbed, and has been quietly acting as the most remote and marginal corner.

After all, although it is increasingly difficult to meet the development needs of the earth's civilization and the needs of the earth's civilization for a broader living space, the meteorite star-sea civilization circle is also a large star field, with a diameter of tens of thousands of light-years.

In such a vast star field, what the earth civilization is most concerned about is, of course, the most core and essence of the ecological planet contiguous areas within the meteorite star sea civilization circle, as for the mineral resource mining areas on the periphery of the meteorite star sea civilization circle, there are too many areas that can be developed and utilized, it can be said that they are inexhaustible at all, and the endless meteorite star belt is enough to provide immeasurable mineral resources for the development of the earth civilization.

There are so many safe mining areas available for use, the earth civilization does not need to stare at some areas with a high degree of danger for development, in fact, it is similar to the dangerous area in the area where the cross-galaxy wormhole passage is located, in the range around the meteorite star sea civilization circle, if you count a little, there are 80,000 if not 100,000, at first glance, they are all similar pit goods, none of them look like there are treasures hidden inside.

If it weren't for the ancient civilization to point out the truth to the earth civilization, then the earth civilization might not be able to discover the special value of this dangerous area after waiting for tens of thousands of years.

However, now that the ancient civilization has revealed the existence of this cross-galaxy wormhole channel, the Earth civilization has immediately realized the great value of this colonial galaxy!

You must know that the wormhole passage linking this colonial galaxy is only less than a hundred light-years away from the periphery of the meteorite Star Sea Civilization Circle, which is not much the same distance as no other for today's earth civilization, and it can be directly linked with the meteorite Star Sea Civilization Circle, the base camp of the earth civilization, and become a high-value living space in the hands of the earth civilization.

As long as the earth civilization reopens the passage between the meteorite star sea civilization circle and this wormhole channel, then all kinds of manpower, material resources, equipment, and population from the meteorite star sea civilization circle can enter this colonial star field without any loss, which not only means that the difficulty of developing the new colonial star field will be greatly reduced, but even the value of the meteorite star sea civilization circle, the base of the earth civilization, will also be greatly increased.

Otherwise, if this wormhole passage is 10,000 light-years away from the meteorite star sea civilization circle, the development cost of the new colonial galaxy will increase too much at once, even if the earth civilization is extremely thirsty for new development space, but due to the fact that the development cost is too large, this new colonial galaxy cannot be developed in a short time, thereby increasing the overall strength of the earth civilization.

But now, because of the unique location of this wormhole passage, which is close to the meteorite Star Sea Civilization Circle, these possible troubles no longer have anything to do with the Earth civilization.

According to the introduction of the ancient civilization, this wormhole passage is so close to the meteorite star sea civilization circle, this is not an accidental accident, this was originally the intentional arrangement of the ancient civilization back then.

The reason why the Meteorite Star Sea Civilization Circle was left behind was not destroyed by the ancient civilization, instead of choosing other star fields, the biggest reason why the ancient civilization considered it was for this cross-galaxy wormhole passage.

It is precisely because the area of the Meteorite Star Sea Civilization Circle is next to the cross-galaxy wormhole passage that this place was finally selected by the ancient civilization and became a place to worship blood food and souls for the ancient civilization for countless years.

The consideration of the ancient civilization back then was that once it returned to the material world from the interdimensional space, the ancient civilization could directly mobilize the shadows that were planted back then, and accept the various legacies left by the ancient civilization in the transportation star sea civilization circle in one fell swoop, and unify the entire meteorite star sea civilization circle.

Then with the help of the power of the meteorite star sea civilization circle, reopen this road to the colonial galaxy, the ancient civilization can just reap the results of the development of the entire colonial galaxy after millions of years, it will be a rich galaxy that is not much worse than the former meteorite star sea galaxy, which must have bred countless interstellar civilizations, with an immeasurable civilization population size, among which a lot of potential, qualified, and valuable high-quality civilizations have been developed.

The ancient civilization hid in the meteorite star sea and developed this huge treasure, which is completely enough to develop to the point of being strong enough, plus there is a good enough host civilization to inherit the science and technology left by the ancient civilization back then, it can be said that even in the face of the threat of cosmic-level civilization, the ancient civilization will not be afraid!

With such a good start, the development of the ancient civilization in the material world does not know how smooth it will be, where is the use of taking risks at every turn, just go desperately! Combined with the power of several powerful scientific and technological civilizations, coupled with the strong strength of the ancient civilizations themselves, it will no longer be difficult to overthrow the domination of the three cosmic-level civilizations and bring them under the banner of the ancient civilizations.

However, it is a pity that there is only the perfect layout left back then, but I didn't expect that the earth civilization, an alien civilization, actually grew up step by step in the meteorite star sea civilization circle, and finally not only overturned all the layout of the ancient civilization in the meteorite star sea civilization circle, but also made the ancient civilization return to the material world deviate from the original layout, the original development plan was completely scrapped all of a sudden, and it slowly embarked on the sinister road that must collide head-on with the cosmic-level civilization.

At this time, it is useless for the ancient civilization to keep the hole card of colonizing the galaxy, and the meteorite star sea civilization circle, the most convenient base camp for the development of the colonial galaxy, has fallen into the hands of the earth civilization, and the ancient civilization has no use for colonizing the galaxy no matter how much it attempts, it is better to transfer it to the earth civilization in exchange for the support and understanding of the earth civilization.

Sure enough, as expected by the ancient civilizations, the Earth civilization has shown great interest in this colonial galaxy. After all, the emergence of this colonial galaxy can be said to have completely met the needs of the earth civilization, and it is much more perfect than the most perfect situation predicted by the earth civilization in advance, and I don't know how much trouble the earth civilization has saved.

As for the problem of the security of the area around the wormhole passage that must be solved in order to develop this colonized galaxy, it is not a problem for the Earth civilization at all.

Ordinary interstellar civilizations have no way to explore the dangerous area around this cross-galaxy wormhole passage, because their technological level is too poor, and they have no achievements in the field of space science and technology, but for the earth civilization, this is an area where the earth civilization has long had a large number of research results.

The latest exploration spacecraft of the earth civilization is equipped with a high-efficiency space-time detection radar, and is the best at dealing with various space traps, space storms, space fault structures, etc., and this dangerous area is a good place for the earth civilization exploration ships to show their skills.

What's more, in the end, this dangerous area is just a little aftermath of the devastating disaster caused by the ancient civilization back then, millions of years have passed, the danger level of this area has long been reduced by countless grades, and there are very few places that can truly be called cosmic disasters.

The earth civilization specially sent a large number of exploration spacecraft to conduct a carpet search of this area, and soon drew a blueprint for the space structure of this dangerous area, and the stable space structure channels that can be safely passed through were quickly found as many as hundreds, each of which can bypass various dangerous disaster areas along the way, and go all the way to the location of the cross-galaxy wormhole channel.

Then the Earth civilization passed directly through this cross-galaxy wormhole passage and came to the location of the colonized galaxy opposite.

To say that the ancient civilization was really cruel back then, in order to block the technological development of the colonial galaxy as much as possible, the ancient civilization did not even leave a chance to pick up garbage for the many technological civilizations in this galaxy.

This side of the colonial galaxy is surrounded by cross-galaxy wormhole passages, and the surrounding areas of hundreds of light years are all directly subordinate star fields of ancient civilizations, and there were once a large number of planets, space bases, industrial facilities, scientific and technological materials, etc. If these things fall into the hands of the technological civilization in this colonial galaxy, I think I also know that with millions of years of development, the scientific and technological civilization here does not know how far it will progress, at least it is absolutely not a problem to cross this wormhole passage and appear in the meteorite star sea civilization circle.

However, this is obviously not something that the ancient civilization wants to see, so when the citizens of the ancient civilization evacuated from this colonial galaxy, they also placed a large number of black hole bombs in their original direct star fields, and as soon as the bomb was activated, a large area of the star field around the wormhole channel was completely destroyed, and even the space structure was completely destroyed, and it has not been completely restored for millions of years, becoming a dangerous environment similar to the other side of the wormhole, in short, it did not leave a little benefit to the local interstellar civilization, and space storms and other cosmic disasters emerged one after another, seriously threatening the survival and development of the surrounding interstellar civilization。

After the exploration spacecraft of the earth civilization came to this colonial galaxy, it quickly detected the correct path to enter and exit the dangerous area here, and intercepted the wireless signals of interstellar civilizations in this colonial galaxy, and obtained a large amount of relevant information.

It turns out that in this colonized galaxy, the area around the intergalactic wormhole passage has also become a marginal area.

When the ancient civilization colonized this large galaxy, because the ancient civilization carried out a major purge of the local civilization every once in a while, killing all the civilizations that the ancient civilization thought that the technological level exceeded the allowable limit, so with the cross-galaxy wormhole channel as the core, it can be said that the most technologically backward area in this large galaxy within a radius of tens of thousands of light years is the core of the cross-galaxy wormhole channel.

The more technologically advanced civilizations in the native civilizations of this large galaxy all live in this area far away from the ancient civilizations, and with the withdrawal of the ancient civilizations from this large galaxy, the interstellar civilizations around the cross-galaxy wormhole passage are not only not able to pick up the civilization heritage left by the ancient civilizations, but also encounter some dangerous situations such as cosmic disasters from time to time, so the various interstellar civilizations around this star field are becoming more and more depressed.

On the contrary, those distant high-tech civilizations that once occupied some marginal areas of this large galaxy took advantage of the situation, and after hundreds of thousands of years of development, they have all become the hegemon-level civilizations in this large galaxy.

However, after the repeated cleaning of the ancient civilizations, there is no interstellar civilization with real advanced technology in this large galaxy, even after millions of years of development, it is not enough to re-master the manufacturing technology of faster-than-light spaceships, such as higher-end military spaceships with faster-than-light strike capabilities, space-time jumping spaceships and other advanced technologies, these interstellar civilizations have not even touched the threshold.

In short, from the perspective of the earth civilization, the native civilization in this large galaxy obviously does not have the strength to threaten the earth civilization at all.
