Perseus Journey
As time went by, humanity set sail and stopped to resupply, then continued its journey. Gradually, humanity discovered that the distances between the stars ahead were getting smaller and the density of the stars was getting larger. Seeing this, everyone realized that Human Civilization was about to truly enter the main domain of the Perseus Arm.
Even the shortest route between the two cantilever arms is nearly 5,000 light-years away. Due to the need for resupply, humans cannot travel in a straight line. In addition, the time spent on resupply means that the actual time spent on the journey is more than 500 years.
After reaching the main body of the Perseus Arm, humanity cannot stop. They must continue along the original route and travel approximately two thousand light-years to reach the actual star region in the star map.
During these hundreds of years spanning the spiral arm, humanity has not only been traveling, but also conducting scientific research and academic studies without stopping. However, because large-scale scientific experiments are not suitable during Warp, research progress in many disciplines has been limited.
Even so, time has allowed humanity to solidify the technological achievements that propelled it to Level 4 Civilization. For example, in the field of Gravity Well, humanity has undergone several iterations, and the results of these technological iterations have been applied to various human creations. The equipment inside the Lyra's floor underwent one round of updates.
Finally, after completing a certain voyage, humanity truly set foot on the Perseus Arm of stars.
Humanity's successful trans-rotor navigation is undoubtedly a historic achievement, and the Covenant's member civilizations are immensely proud of it, as they too participated in this great voyage.
The Milky Way Galaxy has four major spiral arms, the Perseus Arm being one of them, while the Orion Arm is just a small branch of the Sagittarius-Carina Arm.
As a large spiral arm, the Perseus Arm naturally has a far greater number of stars than the Orion Arm. A larger number of stars means a higher probability of civilization arising, and humanity has thus arrived in a much wider world.
From the star map, the position where humans crossed from the Orion Arm to the Perseus Arm is in the latter half of the Perseus Arm. Towards the Galactic Center are the Orion Arm, then the Sagittarius-Carina Arm, the Southern Cross Arm, and further in are the Norma Arm and then the Galactic Nucleus of the Milky Way Galaxy. There, the interstellar density is very high, and it is a gathering of stars, but the environment is also relatively harsh.
Looking outwards from where humanity is, beyond the Perseus Arm itself lies the Norm Arm, beyond which lies only vast emptiness. If one has the ability to travel far, one could continue outwards and leave the Milky Way Galaxy. Beyond the end of the Norma Arm, there is actually a spiral arm formed by the aggregation of stars. According to observational data, it is an extension of the end of the Norma Arm, but humans call it the Outer Arm.
The Outer Arm extends across most of the outer edge of the Milky Way Galaxy, stretching for hundreds of thousands of light-years. It is a sparsely populated star-gathering region outside the Milky Way Galaxy's Galactic Disk, also known as the outer edge of the Milky Way Galaxy. The stars here are usually not included in the diameter of the Milky Way Galaxy because it is so sparse. From a human perspective, it looks like a vast Nebula, giving a feeling of thin fog and thick clouds.
Therefore, if the extended regions of the Outer Arm are also taken into account, the diameter of the Milky Way Galaxy is actually more than 100,000 light-years.
It was through observations of the outer spiral arm that humanity discovered that the rotation speeds inside and outside the Milky Way Galaxy are not the same, thus providing indirect evidence that the invisible and intangible Dark Matter truly exists. It can be said that the Norma Arm Outer Extension Star Region has greatly contributed to the development of human scientific theories.
Unfortunately, humanity currently lacks the capability to reach the extended region of the Perseus Arm, as the vast expanse of space between it and the Milky Way Galaxy's galactic Galactic Disk is simply too immense. Level 4 Civilization's travel technology is far from sufficient; the Void span is on the scale of tens of thousands of light-years. Perhaps only Level 5 Civilization or Level Six Civilization would be capable of traversing that area. Furthermore, based on star maps of the Milky Way Galaxy compiled through years of observation, the shortest route to the extended region of the Perseus Arm is through its tip.
The Milky Way Galaxy is so vast that its expanse can accommodate and give rise to countless civilizations, while also concealing the traces of most civilizations' actions. As a result, in the eyes of many civilizations, the Milky Way Galaxy is a desolate place devoid of any signs of civilization.
The vast scale concealed everything, while at the same time protecting the birth of one Primitive Civilization after another and the growth of one Low-level Civilization after another.
Humanity is one of the lucky ones. Although it suffered an unexpected disaster on the eve of reaching Tier 1 Civilization, it was also protected by the vast galaxy that prevented the Unknown Civilization that destroyed the Solar System from discovering humanity, thus giving it the opportunity to escape and thrive.
The vast Milky Way is like a double-edged sword; it is both the greatest obstacle to communication between civilizations and a natural barrier to protect weaker civilizations.
Just like humanity today, unless we personally send probes to explore each planet in the Target Star System, we cannot discover whether there is intelligent civilization inside a star on an interstellar scale.
Perhaps this is one reason why humanity, having traveled thousands of light-years from the Orion Arm to the Perseus Arm, has yet to discover other civilizations. Perhaps a civilization resides within a nearby star, but neither has detected the other.
It would be better if nothing was found. Humanity is now focused on reaching the Small Universe left by the Precursor and naturally does not want to cause any trouble. Therefore, when arranging for Star Alliance Member Civilizations to explore the safety of the route, they did not send them to Star System outside the route.
Thus, after reaching the Perseus Arm, humanity did not linger. After resupplying, they continued their Starry Road of over two thousand light-years, heading straight for the location shown on the star map.
This is the last stroke of the route with the character "". After this journey, you will reach your destination.
Traveling in the Perseus Arm and the Orion Arm was no different; it was the same process of Warp Speed Travel, resupplying, producing Antimatter fuel, and continuing on. And because they encountered no Alien Civilization during this long journey, humanity enjoyed a rare period of leisure.
Upon arriving in the New Star Region, for safety reasons and to maintain the secrecy of their route, humanity did not resort to bombing planets with Planet Destroyer Cannon to mine resources as frequently as they had when navigating the Orion Arm. After all, that would be too conspicuous. If other civilizations discovered traces of planet-destroying, they could easily trace humanity's route and thus find their destination.
Therefore, after leaving the Star System of the two satellites destroyed by that Unknown Civilization, humanity has been using traditional mining methods to reduce the probability of exposing their flight paths.
Concealing oneself has become one of the means of human survival. Even at the Level 4 Civilization, humanity has not forgotten to be cautious.
