The meaning of galaxy development is found, then Cao Chuan believes that when they explore NGC253, Bode Galaxy, Peacock Galaxy, and IC342 galaxy, there will be no doubts in their hearts.

During this period, the dry tide of civilization continued, and if the data over the years were combined and analyzed, it would be found that the influence of the dry tide gradually stabilized.

"If we wait another 500 years, the Greater Magellanic and Triangulum galaxies will develop more powerfully, which in turn will affect the Milky Way, and the plan to save the Old World can be launched."

Cao Chuan estimated that the human world after being reborn from the ashes would reach unprecedented heights, and now can be regarded as the darkest time before the dawn.

Then, the unknown, who hadn't bothered them for hundreds of years, seemed to move.

On the map of the Milky Way, slightly zoomed out to the scale of several satellite galaxies around it, Cao Chuan noticed a red block adjacent to the central region, which was Ursa's territory.

Since it gained its freedom from the cage of the five-dimensional space, leaving the tide of civilization to humans, it now controls a territory of more than 700,000 planets.

Humanity and Ursa are still at war, so much so that when the immigrant fleet left the galaxy and headed for the Great Magellanic system, Ursa once drove the Unknown Legion to attack.

So on this border, which stretches for about 1,200 light years, two fleets with a total of 20 million soldiers are currently deployed to protect their homes in the rear.

The recent slight increase in the intensity of the conflict in this area is nothing in Cao Chuan's eyes, and this fluctuation is so normal that he will not pay much attention to it until it exceeds the critical value.

Then his gaze fell on the Ring of the Constellation, the territory of Canaiho, whose attempt to land in the galaxy had failed, and she currently held more than 150,000 planets in the direction of the Ring, maintaining its suppression.

Therefore, even if the main target of this group of unknown legions is Ursa, due to the proximity to humans, two more fleets are deployed nearby, forming a cluster-level theater of operations.

Then Cao Chuan's eyes went to the Small Magellanic Galaxy, a place that should not have been explored by humans, and now he found that an unknown army had landed.

They emerged from the black hole and conquered more than 10,000 planets in a very short period of time, with more than 50 V-class unknowns alone, so even if they didn't find the deep dive mother, since they are adjacent to the Big Magellanic System, it seems that humanity is about to face a new crisis.

And after 5 years of continuous observation, Cao Chuan found a familiar figure in the unknown legion in the direction of the Small Magellanic Galaxy, which was the king of the giant mouth, the most powerful life individual that humans had ever dealt with by themselves.

The King of the Giant Mouth was able to coexist with the white dwarf, and in the face of the Star Destroyer Cannon that could tear apart the planets, it took dozens or hundreds of rounds to die completely, but this King of the Giants should not be the one they had ever encountered.

Then, after 10 years of observation, Cao Chuan noticed that the Unknown Legion did not stop in the Small Magellanic Galaxy, and rushed to the other side of the galaxy as quickly as an expedition, establishing a series of jump passages separated by hundreds of light years, and thus through the continuous transportation of the temple type, through the jump, to the direction facing the Big Magellanic Galaxy.

The Unknown Legion is far away from the humans of the Great Magellanic Galaxy, although separated by 50,000 light-years, for the V-class unknown, for this not simple unknown legion, it is not an insurmountable moat, and they may soon follow the star stream upstream.

At the same time that Cao Chuan noticed the abnormality, Xiao Guanhai, as the supreme commander, felt a trace of pressure, because there were too many enemies, and the fronts of the front line merged to form a battle line that stretched for 100,000 light years, not to mention the two deep-diving mother types, the V.-level unknown number of people participating in the battle alone was as high as more than 150, and they approached early, wrapping the Big Magellanic galaxy and wrapping the Orion cantilever, and the goal was too straightforward.

"Did we humans mess with them?" Xiao Guanhai thought to himself: "There's no reason for them to do this, right?" The target is so direct that he intends to take the initiative to attack? ”

Xiao Guanhai had to transfer 1 fleet to change the defense area and go to the Big Magellanic system to guard the frontier and wait for an opportunity.

He observed cautiously, not that he was afraid, the problem was that they were currently a little weak, even if they wanted to take the initiative to fight, due to the existence of such a thing as the withering tide of civilization, they could not exert their full combat effectiveness.

The speed of equipment replacement of 22 fleets has dropped by more than 80 percent, and the last rearmament was 100 years ago.

And even if the outfit is completed, the war with the unknown will never be a blitzkrieg, and if the economic foundation is not laid for 100 or 200 years, the more they fight, the more unfavorable it will be.

At the moment, if it weren't for the fact that many uninhabited planets were maintaining good productivity, it would be a bit difficult to maintain the supply and repair of the current fleet, and maybe in a few centuries, all the starship ships would have to be decommissioned.

"If anyone dares to hit us, we'll strike again!" Xiao Guanhai made his decision, and then literally drew a battle line of 100,000 light-years on the vast map of the galaxy.

That is the bottom line of the unknown invasion that they can tolerate, if they break through this physical bottom line, it also means breaking the bottom line in his heart, and then I am afraid that there will be some conflict no matter what, to defend the safety of mankind.

Cao Chuan noticed Xiao Guanhai's decision, thinking that his choice was not wrong, and sincerely said that this made people feel uncomfortable, and now that the tide of civilization is in a stable stage, he still has to wait for the development of the triangulum galaxy, and he has to wait for the completion of the rule simulation of his "secret weapon".

Then in the past 30 years, during which a full-scale war has not broken out, the tension in the world is still growing, and local conflicts between humanity and the unknown will break out from time to time, such as the occasional fleet will fight with a certain V.-class unknown legion, or the other party will touch the line, and mankind has to resist desperately.

Before the tide of civilization, human beings were about to reach the altitude of the deep diving mother, so even if this level of conflict produced hundreds of millions of casualties, and even the entire planet's population was slaughtered, and the unknown of the entire planet was shattered, it was actually still within the intensity of the war zone.

4 star cluster-level theaters, 56 stellar theaters, dragged the 22 fleets of the East Galaxy Company plus 8 billion local troops, and dragged 150 V.-level unknown led legions, forming a war-torn frontier.

The matter is not over yet, because at this time, another wave of unknown legions appeared. (To be continued.) )
