In fact, among the four second-rate top civilizations, the most mysterious is not the Kunyang clan, but the Extreme Realm clan. In addition, among the four second-rate top-level civilizations, only the native star system of the Extreme Realm Race is not in the central region, but in the southern region, and the living environment is also extremely harsh.

There has always been controversy about the origin of the Extreme Realm.

Quite simply, the Polar Realm is clearly different from other civilizations of the Galactic Alliance, and some people even believe that the Polar Realm is not a civilization from the galaxy at all. That is, the Polar Race is an intelligent creature that evolved from aquatic creatures. Although they have long since gotten rid of the primitive living environment and have the ability to survive on land, many of the essences inherited from genes have not changed, which makes the Extreme Realm people unique. For example, the Polar Realm has a high requirement for water in the living environment, and as long as there are conditions, most of the Polar Realm people are willing to live near water sources. In addition, the Arctic still produces and raises offspring in the water, and are typically oviparous creatures. Although thanks to science and technology, the way the Arctic people reproduce has changed a lot, but the social structure derived from the reproduction mode has not fundamentally changed, that is, the Extreme Realm is still mainly matrilineal, so it is the queen, not the king, who rules the Extreme Realm.

It was these differences that prevented the Polar Realm from integrating into the Galactic Alliance for a long time.

At least, when they came to the Southern Alpha System, none of the civilizations regarded the Polar Race as an ally, and there were even many civilizations that considered the Polar Race to be an indigenous civilization. As a result, while other civilizations were looking for a place to stay, the Extreme Realm was ostracized by all civilizations, including the top civilizations. Because they were not accepted, the Extreme Realm Clan could not gain a foothold in the central region, and could only go to the periphery. In fact, when the Polar Realm Race was looking for a foothold to live and reproduce, the star systems in the Southern Alpha System with superior environments had been carved up, and the rest were all some star systems with harsh environments, lack of resources, and no development value.

As such, the native star system of the Polar Realm is far from the central region of the Southern Incident System, and there is only one planet that is barely suitable for carbon-based life. The terrestrial planet is just around the outer edge of the stellar life belt, and the aphelion is very different from the perihelion. As a result, the surface temperature of the planet drops below freezing when it orbits to its original perihelion, and above freezing when it orbits to perihelion. Fortunately, the planet's geology is very active, and the tidal gravity generated by the revolution provides a huge amount of energy, so even when the water on the planet's surface freezes at aphelion, there is still liquid water below the ice above freezing. Because no civilization wants to live under the ice, no civilization is interested in this planet, and this star system. In fact, the Extreme Realm Clan is not very accustomed to the environment here, but has no choice.

Obviously, no one could have imagined that the Extreme Realm Clan would be a blessing in disguise.

In order to survive in the harsh environment, the Extreme Realm must give up and work hard. As a result, the Polar Realm returned to its original state here. Although it has only been a short period of more than a hundred years, in the battle against the harsh natural environment, the Extreme Realm Clan has completed the re-evolution at an extremely fast speed. Of course, it is also related to advanced technology. To put it simply, the harsh environment has made the Extreme Realm Clan stronger, with more tenacious vitality, and has also learned how to master and use natural conditions to enhance their abilities. What's more, the re-evolution of the Polar Race took place under the ice, and it was not discovered by the outside world, nor did it attract attention from the outside world.

In this short period of more than a hundred years, the Extreme Realm Race has built an extremely prosperous world under the ice, a world that other civilizations cannot imagine at all, a world that only belongs to the Extreme Realm Clan, and can only be used by the Extreme Realm Clan, and once again embarked on the path of technological development.

It can be said that the greatest achievement of the Extreme Realm Race is actually its own evolution.

Among all the civilizations of the Galactic Alliance, the Polar Realm was the first to grasp the mysteries of the original body, and the first civilization to achieve the original through scientific and technological means. In other words, the Extreme Realm Clan can use the power of technology to make any clan have the original body at birth!

Obviously, this is a remarkable achievement.

You must know that even the three first-class top civilizations began to research the technology of the original body after the First Greenwich War in order to deal with the powerful Silicon Charm Alliance, and finally achieved complete originalization, thus gaining a solid foundation to surpass other civilizations.

It's just that before the First Greenwich War, no one knew what the Arctic had achieved.

In fact, at that time, not many people even knew about the existence of the Extreme Realm Clan. To put it bluntly, no one cares about the Extreme Realm Clan at all.

Like the Kunyang and Bingyu clans, it was the First Greenwich War that made the Polar Realm clan widely known.

When the Kunyang clan's legion went to resist the Silicon Charm army, the Extreme Realm clan also sent a legion. Although no civilization took this seriously, not even the Bright Holy Emperor, a battle soon after, completely changed everyone's opinion of the Extreme Realm.

That is, when the Kunyang Clan's legion was in a desperate situation, and the three million soldiers of the three hundred legions fought to less than 500,000 left, the Extreme Realm Clan Legion who rushed to the battlefield in time turned the tide, not only defeated the fierce Silicon Charm army in one fell swoop, but also took advantage of the situation to launch a counterattack and recapture several lost star systems. By the time the Kunyang clan's legions were reorganized, the tide of the battle had stabilized.

It can be said that the Extreme Realm Clan became famous in a fight.

It was also this battle that made the Extreme Realm Clan and the Kunyang Clan hardcore allies.

According to rumors from the outside world, after the birth of the Extreme Realm Clan, they first provided the Kunyang Clan with the original technology to help the Kunyang Clan solve the problem of lack of soldiers. In return, the Kunyang Clan shared the technology of making small Origin Converters, and provided a large number of small Origin Converters to the Extreme Realm Clan. Obviously, without the primordial technology provided by the Extreme Realm Clan, the Kunyang Clan would not have been able to arm enough soldiers with such a small population in such a short period of time. Similarly, without the technology of the small Origin Converter provided by the Kunyang Clan, the Polar Realm Clan would not have been able to grow and become a powerful advanced civilization during the First Greenwich War.

What's more, the relationship between the Extreme Realm Clan and the Kunyang Clan has been maintained and has never changed for thousands of years.

In the rebel war, the Extreme Realm Clan responded to the call of the Kunyang Clan at the first time and joined the rebel camp. When the Holy Emperor of Light came forward to recruit the Kunyang Clan and used the Lei Ling Clan's brave and resolute team to force the Kunyang Clan to surrender, the only request made by the Kunyang Clan was to advance and retreat with the Extreme Realm Clan.

With the situation at that time, if the Kunyang Clan had not come forward, the Bright Holy Emperor would definitely not have recruited the Extreme Realm Clan. The reason is very simple, the Extreme Realm Clan does not have the capital to let Guangming survive Zhao'an. Although in all aspects, the strength of the Extreme Realm Clan is not bad, but there is no particularly outstanding advantage. For example, without the powerful fleet of the Soldier Domain Clan, and without the warrior corps of the Kunyang Clan, the Extreme Realm Clan would have no irreplaceable value.

It is precisely in this way that after surviving by "luck", the Extreme Realm Clan embarked on a completely different path from the Kunyang Clan.

Before the outbreak of the Second Greenwich War, the Arctic had swept across the southern region, destroying more than half of the civilizations, while the rest were all subservient to the Arctic Clan. Although the three first-class top civilizations have expressed their condemnation, and they have also pushed the Galactic Alliance Council to issue a sanction resolution against the Polar Realm, it has not produced any effect, and the Polar Realm Race still goes its own way, not taking the condemnation of the first-class top civilization in their eyes, let alone treating the sanctions of the Galactic Alliance Council as a trouble. Because the threat of the Silicon Charm Alliance has not been eliminated, and the next war may break out at any time, the three first-class top civilizations have not taken military action against the Extreme Realm Clan.

This situation was maintained until the outbreak of the Second Greenwich War.

In this war, the Extreme Realm still charged into battle, making great contributions to defeating the invading Silicon Charm army, and their military strength increased by leaps and bounds. As a result, after the end of the Second Greenwich War, the Arctic swept through the entire southern region with a thunderbolt. By the time the three first-class top-level civilizations suddenly came back to their senses, the Southern Region was already under the control of the Extreme Realm Clan and had become the territory of the Extreme Realm Clan.

If you just control the southern region, it is not a big deal, after all, the southern region is very desolate and has little value.

What makes the three first-class top civilizations unbearable is that the Extreme Realm Clan has also blocked the Southern Region, and all spaceships entering and leaving the Southern Region must be approved, otherwise they will be destroyed after being discovered, even the ships of the three first-class top civilizations are no exception.

This move almost triggered the second civil war of the Galactic Alliance.

At the voting meeting of the Galactic Alliance Council to decide whether to send troops to the Southern Region, second-rate top civilizations such as the Kunyang Clan, as well as more than half of the high-level civilizations, voted against. What's more, at that time, the Hidden Spirit Clan had already lost power, and the Lei Ling Clan and the Weaver Star Clan were eager to try, so they took this opportunity to suppress the Hidden Spirit Clan and abstained from voting, so this vote finally rejected the proposal put forward by the Hidden Spirit Clan with a narrow majority. However, the Polar Realm also had a clear understanding, and shortly thereafter announced the unconditional opening of the Southern Region to other civilizations, but it was necessary to declare and file in advance, and other civilizations were allowed to open consulates in several designated star systems.

It's just that, for thousands of years, no civilization has been able to operate unhindered in the southern region.

To put it bluntly, the ships of other civilizations will be monitored after entering the Southern Region, and they can only sail on the specified routes. If you deviate from the route, or if there is another accident, such as the disappearance of the crew, you will not only be disqualified from entering the Southern Region, but you will also be sanctioned by the Extreme Realm. As for the ships that entered the Southern Region without declaration, they would be attacked if they were discovered.

It is precisely because of this that the Polar Realm appears to be extremely mysterious and alien to the other civilizations of the Galactic Alliance. (To be continued.) )
