One thing that remains in the air in humanity's strategy against the unknown is that Ursa, whose past cannot be deduced, and to which great being it belongs to, but Ursa is so powerful that it is not to be underestimated.

So for the next three years, Cao Chuan and the East Galaxy Company tried almost everything possible to dig into the secrets of Ursa and find out where it would stand in the next few hundred years.

The first method is the spies lurking in the unknown lair, with the existence of spies being gradually excavated in recent years, and the manipulation of unknown corpses must rely on a strong health level, it is difficult to penetrate into the ranks of the powerful unknown, resulting in the intelligence bureau has extremely limited information mining of the most powerful unknown, and as a result, it has not been able to find the secrets of Ursa in this way.

The second method is for Cao Chuan to go to the five-dimensional world where Ursa's brain is imprisoned again and try to "get in touch" with it. Human diplomacy with the unknown is futile, but Cao Chuan believes that he will find clues from his conversations with Ursa and thus help them in their judgment.

Unfortunately, Ursa's brain had long since left the heart of the former Nexus, and his attempts failed once again.

"It's a cunning guy, I don't know if it's intentional or something else." Cao Chuan was a little depressed when he discovered that there was no other way to reach this terrible unknown, but he was soon attracted by the recent series of archaeological activities in the central area and on the cantilever.

space-time bubble, a special spatial structure that seals ancient light; Alien relics, ancient civilizations that have fought against the unknown, most of them show the same origin as humans, through professional consideration activities, often can get a lot of useful information from the above two, as for others, such as unknown nests, planet ruins, because they cannot be preserved with the years, the value is relatively average.

Researchers still working in the area have found another alien remnant that fought Ursa, dated 5.5 million years ago, suggesting that Ursa had arrived in the galaxy at an earlier point in time.

By deciphering the records left by the aliens, they found more information about the size of the Legion at the time and the situation in the starry sky at that time, and deduced that Ursa first appeared 6.5 million years ago, and since that point in time, it has taken root in the galaxy and expanded.

There were some more new clues, and then to Cao Chuan's delight, the researchers found the place where Ursa first appeared, and the place where it now became a dark void, by reviewing the galaxy 6.5 million years ago and comparing it with today.

The space-time bubble was unsealed, revealing more new clues, and they saw Ursa's arrival through the Jump Portal.

It was the first attack on Ursa, the second 5 million years ago.

The quantum computer pinpointed the starry sky at that time, which was a completely unknown supercluster, which was not in any known spatial structure, such as the Great Wall of Sloan, the Great Wall of Wuxian-Northern Corona, but from the point of view, it was at the very edge of the universe.

The universe expands day after day, constantly widening the distance of star space, and in the edge of the universe, it is an extremely barren area, there may be quasars, light at the beginning of the universe, matter at the beginning of the universe and other interesting things, but they are really too far apart, from the perspective of development, it is a barren land.

Ursa was born there, and then through the special promotion system of unknown civilizations, Ursa quickly reached the height of Class VI life.

It's a pity that it grows too fast, like a meteor across the sky, so that it has to face an existence that it can't compete with at all, and a VII. class unknown head.

That's when Ursa was devastated and had to flee for the first time, crossing galaxy after galaxy for nearly 10 billion light-years to settle down in this place.

The discovery of the space-time bubble is mainly like this, and everything after that is known, such as what happened to Ursa in the Peacock-Indian supercluster, only to be hit hard for the second time in the Milky Way.

"So, are the above more secrets of Ursa? Let's ignore the history of the edge of the universe, after all, there is too much research to be done, and it has little to do with human beings. ”

"If you look at these events, Ursa is definitely not a safe guy." Cao Chuan muttered, through so many facts, it was reflected that Ursa was definitely not a low-key guy, so he could judge what choice it would make next.

"For example, the ideal situation is undoubtedly that during the period when humanity is desperately resisting Canaiho, as well as the unknown legion in the direction of the Silver Heart and the Magellanic galaxy, Ursa will attack brazenly, relying on the legion at hand, destroying trillions of enemies and reducing the pressure on humanity."

Cao Chuan said that the most ideal situation is true, but in fact Ursa may not choose this way, if it thinks that humans are more worthy of its deal, then maybe it will take the opportunity to deal with humans.

In this way, humanity will face the worst situation, because it is equivalent to the fact that except for the relatively safe direction of the Magellanic system, the remaining three sides will be attacked, and humanity will not be able to resist the attack of so many unknown legions.

Of course, during this period, there may be small questions such as whether the aftermath of the civilization dry tide will affect the opponents, and it is unknown whether the legions will fight when they attack the humans.

Ideally, there is no need to consider the best situation, Cao Chuan believes that it is necessary to consider what kind of response they will make if Ursa thinks that the threat to humans is greater and chooses to attack them.

"Abandon the galaxy?" Such an idea suddenly came to his mind, at least in the Large Magellanic Galaxy and the Triangulum Galaxy, human beings have taken root for many years, and it will not take a few hundred years to restore to their former heights, and it is even more difficult for the unknown legion to invade there, so it is worth choosing the strategy of losing pawns and protecting cars.

And this is the worst case, but under normal circumstances, the human world has such a great depth, unless it is a completely one-sided war, the war will definitely last for a long time, and there is no need to worry that all this will end early.

"Therefore, the worst case is actually not so bad, let me quickly simulate that technology, and human beings will master the most absolute means of safe development, and no matter how specific it is dealt with at that time, I will be at ease."

Cao Chuan weighed it, and finally continued the rule simulation, spending 500 years, 1000 years to get that technology out, so that when the tide of civilization ends, even if the unknown threat intensifies, human beings can still be revived openly, without worrying about being coveted.
