There was no detection of the opening of a space channel, nor were there any traces of a space jump.
However, the Milky Way had appeared here without any warning.
This surprised everyone in Hangu Pass's command center.
What kind of technology is this battleship using?
At this moment, Bai Zixuan, who was more than 100,000 light-years away, finally regained communication with the Milky Way. His heart, which had been hanging in the air, finally relaxed.
A distance of 160,000 light-years, a total time of hours, 48 minutes, and 17 seconds!
Perhaps this is a very low efficiency compared to space teleportation.
However, as mentioned before, hyperspace technology has an advantage that space teleportation technology can't compare to.
The most important thing is that this is only the first generation of the hyperspace engine, this technology still has a lot of room for improvement!!
It didn't take long for the first test report of the hyperspace engine to be placed in front of Lin Fan.
Originally, Lin Fan only planned to wait for Bai Zixuan to develop the intergalactic space teleportation technology, then immediately start the exploration plan of the outer galaxy.
However, what he didn't expect was that Bai Zixuan, who owned the Dark Star, was very disdainful of the intergalactic space teleportation technology he gave him, and directly threw it to his subordinates for research.
At most, Bai Zixuan himself would check the progress every once in a while and guide the technical problems. The rest of the time, he spent most of his time on the Dark Star.
What Lin Fan didn't expect was that Bai Zixuan could develop this technology in just a few years.
Although there was still a big gap compared to the hyperspace engine on the Dark Star, at least it was there, right?
After that, he only needed to do in-depth research step by step, then gradually introduce the second generation and the third generation!
As the commander-in-chief of the Federation fleet, how could Lin Fan not see the military use of the hyperspace engine?
Although space teleportation was fast, it required a special device. After all, a battleship couldn't teleport itself, right?
The other problem was the issue of combat efficiency.
If it was a large-scale battle and they used spatial teleportation, it would take a long time to teleport all the fleets to the frontlines.
Even if they used a super stargate, it would take at least an hour to send 100 million battleships up. After all, the stargate was only so big, and the number of battleships that could pass through it at a time was extremely limited.
However, the hyperspace engine did not have such a problem. It could be installed in every battleship.
As such, no matter how large a fleet was gathered, it would not be affected at all.
Of course, this didn't mean that teleportation technology was useless and could be eliminated!
In fact, it still had a certain advantage in the rapid delivery of small-scale military forces. In addition, it also had an irreplaceable position in civilian use.
For example, the Stargate Network that was spread all over the Federation.
In the past, when you wanted to go from one planet to another, you had to take a shuttle to space, then take a spaceship to the orbit of the target planet, and finally take a shuttle to the surface of the planet.
Ever since the Federation used small stargates to form a stargate network, people didn't even need to take a spaceship to travel. They could directly reach their destination through the stargate on the planet.
Convenient and fast!
Therefore, it could only be said that each had its own advantages. Of course, from a military perspective, the hyperspace engine was definitely more advantageous!
Soon, a year flew by. It was now Year 114 of the Federation's calendar.
Now, galactic teleportation arrays created by intergalactic teleportation technology had been set up on every main spiral arm.
At the same time, the civilizations on the main spiral arms also began a vigorous migration plan to the outer planets.
Just like the information provided by the humans, because the other galaxies did not have the existence of the Path of Stars, the development of civilizations was extremely slow. It was as if there was an invisible barrier that prevented all civilizations from taking that crucial step before they became a level-4 civilization.
It should be known that without the Path of Stars, it was very difficult for a level-3 civilization to expand. Generally speaking, having three to five star systems was already considered a very strong level-3 civilization.
After all, without the Path of Stars and the hyperspace technology of level-4 civilizations, a level-3 civilization could only travel through space at sub-light speed.
The distance between two star systems was calculated in light years. Just relying on the sublight engine to travel to other star systems would take at least a few decades.
Even some civilizations that had been around for tens of thousands of years generally did not have more than five star systems. Otherwise, a journey that could easily take decades would not be able to be effectively managed!
Only some civilizations with extremely high talent and potential could overcome this difficulty and become a level-4 civilization!
In short, according to the reports of the affiliated civilizations, so far, of the more than ten galaxies that they had set foot in, only five had level-4 civilizations, and they were all extremely weak early-stage level-4 civilizations.
Not to mention the Vera Alliance, even some level-3 civilizations that hired the fleets of other level-4 civilizations to escort them were not something that the level-4 civilizations could fight against.
Therefore, the entire migration plan was proceeding unusually smoothly. According to this progress, all the civilizations in the Milky Way would be able to complete the migration according to the plan in at most ten years.
However, Lin Fan's main thoughts were not in this regard. After all, this result had long been expected!
-----
2.2 million light years away from the Milky Way, at the edge of the Andromeda Galaxy.
"Is this the Andromeda Galaxy?"
Lin Tian stood in the bridge and looked through the porthole at the starry sky outside the ship as he muttered to himself.
Speaking of the Andromeda Galaxy, its diameter was about 1.6 times that of the Milky Way, and the number of stars it had was more than ten times that of the Milky Way, reaching more than one trillion stars.
It could be said that in the Local Group, the total number of stars of the other 49 galaxies added together could not compare to the Andromeda Galaxy.
This showed how rich the Andromeda Galaxy was.
The Andromeda Galaxy was a rod spiral galaxy, which was different from the spiral structure of the Milky Way. Therefore, it did not have so many main spiral arms and secondary spiral arms like the Milky Way. The result was relatively simple, with only two spiral arms extending from the two sides of the rod.
Now, the Galaxy level fleet led by Lin Yu was at the end of the front main spiral arm of the Andromeda Galaxy, which was also the edge of the galaxy.
However, even at the edge of the galaxy, according to the astronomers on the ship, the star density here was about the same as some of the rich star fields on the four main spiral arms of the Milky Way.
"How rich is the Andromeda Galaxy?"
After listening to the report of the astronomers on the ship, Lin Yu could not help but exclaim.
