The Andromeda Galaxy is a spiral galaxy, and the first phase of this outside-in war is to occupy the entire cantilevered edge of the periphery, which will serve as a base for the relocation of the Empire. It is well known that the margins of a large river system are the environments where habitable planets are most likely to occur.

The primary goal of the four deputy commanders is to occupy all suitable systems as habitats. The long-term goal is to enter the interior of the Andromeda galaxy and wipe out silicon-based life in an environment that is unfavorable to you.

The Imperial fleet advanced on all fronts, but at first it didn't encounter a place that could be called resistance, the Andromeda galaxy is too big, and such a large galaxy can be said to be able to meet an enemy who resists casually, which is not much more likely than a comet smashing its head.

Promote, identify, discover, clear! This is the most likely scenario at the beginning of the war, and the unlikely scenario at the beginning is to come up and fight a decisive battle with silicon-based life, even if the Imperial fleet is ready to encounter silicon-based life at any moment.

The starry sky is eternal, a fleet with a cross-section of more than a thousand light-years is moving in a dragnet formation, under the dark starry sky nearby, the fleet moving at an average speed because there is no reference, it looks like a fish trapped in the ice, it cannot feel that he is advancing, and some soldiers even think that their battleship is a little behind, so that at least they can hear the sound of the engine and know that they are still moving.

According to the distance, as a regional fleet under the Imperial Police Fleet, the fleet led by Ringer has been deep into the Andromeda Galaxy for 350 light years, and as it continues to go deeper, the warships in his hands will be constantly diluted, and the separated warships will enter some star systems for carpet searching, and set spatial coordinates to confirm safety to the rear.

"The Imperial Viking fleet seems to be in a bit of trouble, they have discovered a first-level civilization at the planetary system level, and the subordinate warships have launched an attack, but this civilization is not strong in combat, and I believe it will not slow down the pace of the Viking fleet." At the side of Ringer, the chief of staff of the regional corps, Bel Klausa, recounted the latest situation, "I believe that two days is enough time for the Viking fleet to rid this civilization and fill in the honor of our war." ”

"We had just entered the edge of the Andromeda Galaxy, and we came across a first-level civilization. Krausa? Ringer suddenly asked with a strange expression, "The Earth is actually on the edge of the galaxy, right?" If you think about it, did our ancestors also suffer the catastrophe of annihilation? Maybe the Earth hasn't been destroyed a few times, but we just don't know it. ”

This can't be blamed on Ringer's brain, who made this kind of cantilever planetary civilization in the position too similar to the earth. The Andromeda Galaxy and the Milky Way are both great river systems in their prime, and with such proximity, it's not surprising that there are some similarities.

"Captain, this joke is not funny, but the Viking fleet is not the first fleet to encounter a situation, the Northern Fleet has encountered a race that is suspected of evolving into intelligent creatures, but this species is not even a civilization, the Northern Fleet has decentralised combat robots, and I believe that this small problem can be solved without taking action in person."

"What I like the most is this kind of strength that has nothing to do with you when I kill you, and now I have more and more expectations for the experience of serving in the Empire!" Ringer glanced at Klausa and smiled coldly.

Half an hour later, Ringer sent another flagship team into a tiny star system. The Grand Fleet waited on the periphery, and it didn't take long for the flagship team to enter the star system to come out, and the flag captain Serra reported through the fleet channel, "This star system is a barren star system, there are only two planets in it, a rock planet, a gas planet, the two planets are far away, there are not even many satellites in the star system, there are many meteorite belts, but the rocky planet is just within the range of the habitable zone, and there are conditions for breeding life, but according to our exploration, it seems that here? ”

"Seems to be wrong?" Chief of Staff Klausa asked impatiently, "Didn't probe and understand?" ”

"The exploration understands that the planet located in the habitable zone has had a nuclear war, and the species has been degraded. The only thing we don't understand is what caused the war. Captain Serra immediately reported, apparently Klausa's questioning to tell him the truth.

"Transmit the image." Silent Ringer commanded, and then waited quietly. It didn't take long for the complete exploration image to be transmitted, and all the staff officers sighed at a glance, and sure enough, as Captain Qi said, this star system seemed to be a little empty.

"This gaseous planet is too far away from a rocky planet, which is too bad for space exploration. Nearly a third farther than Neptune is from Earth, there are no gaseous planets around the rocky planet that can be used for energy. Unless the exploration technology is sufficient to claim to exploit underground resources, it will be extremely difficult to break through the constraints of the planet and enter space. Then the cause of nuclear war may be caused by the depletion of surface resources. "What Ringer learned from Dr. Mengele can be of some use here, life is not easy, and the journey of evolution is a trap at any time. A star system like this is a difficult challenge for a civilization in terms of innate conditions.

And in case of encountering an organization like the SS, it is also a disaster for other civilizations, in fact, the current empire is also a big filter for ordinary civilizations, as long as it is discovered in the process of advancing the imperial fleet, it will be completely destroyed, and it will not be long, and the regional fleets will converge and continue to advance.

Because of the different environment in which ordinary imperial officers grew up, Ringer did not understand at first why almost every officer had a wealth of astronomical knowledge, but now he understood that after many years of sailing in the starry sky, even a person who was not interested in astronomy at all could become an astronomical expert with his ears and eyes.

A few days later, the regional fleet also detected a binary star system, two white dwarfs devouring each other, one of which was significantly smaller than the other, and it was not known how long before the smaller white dwarf was completely peeled off and became part of the other white dwarf.

"I always felt that this advance was too smooth, this time we raised our alert, but the whole line has been advancing for almost three light years, and last time we were already engaged with the silicon giants at half the distance." Ringer tapped on the alloy wall in front of him and said to Krausa, "Communicate with the brother fleet to see if there are any abnormalities in the other fleets." ”
