For humans who have been entrenched in the North 4 for thousands of years, the Southern Region is a very distant place, similar to the North Alpha Galaxy. Purely at a distance, going from the home galaxy to the most remote star system in the Southern Region is comparable to going through the Greenwich Meteorite Belt to the North Alpha System. As for what the southern region looks like, Yang Yi doesn't know at all, let alone knows anything.

There is nothing surprising that for thousands of years, apart from the envoys sent to the Extreme Realm, there are very few humans who have been to the Southern Region. Even Xiao Wentian, who swept through the top civilization many years ago, did not go to the Southern Region. It's not that he doesn't want to go, but before that, he listened to the Empress of the Weaver Clan and went to the North Alpha System. Besides, after defeating the king-level powerhouse of the first-class top civilization, Xiao Wentian didn't take the second-rate top-level Owen king-level powerhouse seriously, and no one would think that he didn't go to the southern region to challenge the queen of the Extreme Realm Clan, and he was not the opponent of the Queen of the Extreme Realm. Very simply, when Xiao Wentian challenged the top civilization, the queen of the Extreme Realm Clan did not come forward. Whatever the reason, at least in the eyes of outsiders, the queen of the Extreme Realm Clan is definitely not Xiao Wentian's opponent.

Because envoys can only operate in a specified area, for thousands of years, the Human Federation has not known about the Polar Race at all, and has no contact with the Extreme Race.

In fact, humans don't know much about the southern region.

In terms of scale, the Southern Region is the largest region of the Southern Alpha Galaxy, accounting for about one-third of the Southern Alpha Galaxy. It's just that the southern region is very inhospitable, arguably the most inhospitable region of the Southern Alpha galaxy and the lowest density of star systems. In the Southern Region, the average distance between adjacent galaxies is more than 100 light-years, while the Northern 4 Region is only about 20 light-years. As a result, although the Southern Region accounts for one-third of the volume of the Southern Alpha Galaxy, the number of star systems accounts for only one-tenth of the total, and the total mass of the star system is only one-fiftieth of the total. To put it simply, the Southern Region is a desolate area.

Of course, there is nothing surprising about this.

Scientists have long proven that the North and South Alpha Galaxy was originally a star system, and that the current Greenwich Meteorite Belt was the central black hole of that star system billions of years ago. Due to an unexplained catastrophe, the central black hole collapsed and exploded to form what is now the Greenwich meteorite belt, and the star system was split into two parts. Although the catastrophe came suddenly, the division of the star system is a relatively long and repetitive, interacting process. It took hundreds of millions of years for two associated star systems to finally form. During this long period of time, both star systems expanded rapidly, and a large number of star systems escaped during this period.

Previously, scientists have found several isolated star systems near the South Alpha System, and have proven that these theoretically impossible star systems escaped from the South Alpha System. In the process of expansion, the outer galaxies are the fastest and are most likely to break free from the gravitational constraints of the star system and escape into isolated star systems. Of course, these peripheral galaxies also move the fastest. After hundreds of millions of years of slow evolution, these galaxies are extremely far away from their centers. Although the vast majority of galaxies do not escape the gravitational field of the star system, the star systems at the edge of the star system are also extremely rare.

This is the main reason why the southern region is vast and inhospitable.

In addition, there are a number of star systems from the North Alpha system in the Southern Region.

Scientists have found four star systems with distinct characteristics, and have proved that these star systems belonged to the North Alpha Galaxy hundreds of millions of years ago, or even more, and may have even escaped the North Alpha System, only to be captured by the gravitational field of the South Alpha Galaxy in the process of slow motion, and eventually became members of the South Alpha System. Of course, at that time, the Silicon Alliance did not exist.

Because the distance between the galaxies is so far apart, even the Polar Realm cannot control all the galaxies in the southern region. The point is, some remote star systems are too small, not only are they harsh, but they also don't have resources that are worth exploiting. If you send troops to occupy and control these star systems, the resources and benefits you will get may not be enough to maintain the daily expenses of the garrison.

Of course, this is not to say that the southern region is useless.

In the Southern Region, there are about 100 star systems with terrestrial planets in suitable environments, and twice as many star systems as rich in resources. The Arctic Clan mainly controls these star systems, and has also deployed heavy troops and built military fortresses in these star systems. For other civilizations, the perception of the Southern Regions has also focused on these star systems. For example, envoys from other civilizations can only operate in these star systems.

As for the home planet of the Extreme Realm Clan, it is actually not dazzling.

When they came to the Southern Alpha Galaxy, the Polar Race was extremely weak, inconspicuous, and even regarded as an alternative, so the star system where they settled was extremely remote, and there was not even an indigenous civilization, but only a harsh environment and resources that could barely allow the Polar Race to live and reproduce.

As the Polar Race grows and becomes a second-rate top-tier civilization with more star systems, the home planet is no longer the only home. More than 3,000 years ago, after the end of the Third Greenwich War, the Polar Realm people migrated as a whole, and the home planet became a forbidden place for idlers to enter. Like the Weaver Clan, the home planet is managed by the royal family of the Extreme Realm, not to mention people from other civilizations, even people from the Extreme Realm cannot go to the home planet casually.

Of course, no civilization cares about a remote, inhospitable planet.

Besides, after the Polar Realm Clan dominated the Southern Region and controlled all star systems, it was very troublesome for other civilizations to enter and exit the Southern Region, and even if the Extreme Realm Clan later lifted the restrictions, the envoys of other civilizations could not move at will. Because of the little knowledge of the Southern Region, none of the aliens had the ability to go to the home planet of the Polar Realm alone. As for making a request to the Extreme Realm, it obviously doesn't make much sense. For thousands of years, even when a new queen ascended the throne and was crowned, the Polar Realm did not open their home planet to the outside world, but instead entertained the envoys of various civilizations elsewhere. In addition, shortly after the end of the Third Greenwich War, the Polar Realm removed the home star from the star charts.

It is precisely because of this that it is almost impossible for a foreigner to sneak to the home planet of the Extreme Realm Clan.

"Actually, we have been suspecting that the Extreme Realm Clan must have been covering up an ulterior secret when they left their home planet and made it a forbidden area, even if they were from their own clan. You must know that the Divine Mother Star of the Star Weaver Clan is also a forbidden area, but it is not so mysterious. Not to mention anything else, when the Empress of the Weaver Clan is crowned, she will invite envoys from other civilizations to the Mother Planet, and we all know where the Mother Star is. However, the Extreme Realm Clan went even further, not only forbidding any foreigners to go to their home planet, but also deleting the coordinates of the home planet on the star map. In order to prevent accidents, the Arctic Clan even modified several routes from the vicinity of the home planet, which cost a lot of resources. ”

"Is this just your guess?"

"It's not just speculation." Amy sighed and added, "For more than two thousand years, we've been trying to gather relevant intelligence, and we've sent spy ships to the Southern Regions many times. It's just that all our efforts have failed, all the spy ships sent out are missing, and none of them have sent back valuable information before they go missing. It's just that, we don't suspect the Extreme Realm Clan, after all, the Extreme Realm Clan has already blocked the southern region, and has mastered advanced technology, and has a military force stronger than other civilizations, so it is not difficult to discover our spy ship and destroy our spy spaceship. It's just that a fortuitous discovery makes us think that things are not so simple. ”

"What discovery?"

Amy pondered for a moment before she said, "About two thousand years ago, shortly after the end of the Third Greenwich War, we sent several spy ships to the Southern Regions to gather intelligence. Because we have suffered defeats before this, and we have also caused some trouble, mainly because the crew was captured by the Extreme Realm Clan, so we can't deny the fact that the spy spaceship was sent, so all the ships sent out this time are unmanned spaceships, even if they are discovered by the Extreme Realm Clan, or even destroyed, it will not have anything to do with us, at least the Extreme Realm Clan can't blame us because of a few spaceships. These ships have pre-programmed routes, even the nodes of each space jump, and their sole mission is to gather information on their routes. If, one day in the future, we have to go to war with the Extreme Realm, the information collected by these ships will allow us to open up a direct route to the rear of the Extreme Realm as quickly as possible, allowing us to take the initiative on the battlefield. ”

Yang Yi nodded slightly and let Amy continue.

"Because it is to prepare for war, there is a spaceship destined for the home planet of the Polar Realm, a star system near the home planet of the Polar Realm to be exact. Of course, this ship is also the most advanced. In order to avoid being alarmed, other ships were sent to other parts of the Southern Region. Unfortunately, after entering the Southern Region, the ship, like the other ships, disappeared after making a few space jumps. Amy paused for a moment before she said, "Because all the spy ships we sent out suddenly disappeared, we didn't make a big deal about it, and we didn't pay attention to the ship. At that time, we thought that we had accidentally leaked the news, and the Extreme Realm Clan had been alerted. ”

"And then?"

"And then it's hundreds of years later." Amy smiled wryly and sighed, "A few hundred years later, the Fourth Greenwich War broke out. Later in the war, when we launched a counterattack and attacked the Greenwich Meteorite Belt, we received a signal that we followed to find the wreckage of a ship. ”

"You mean ......"

"It's the wreckage of the spy ship that was sent to the home planet of the Arctic Clan and suddenly disappeared, and it's in the heart of the Greenwich Meteorite Belt, more than a thousand light-years away from the North Fourth Region and tens of thousands of light years away from the Southern Region. Obviously, the spy ship could never have been inside the Greenwich meteorite belt. (To be continued.) )
