"It's a pleasure to cooperate. This is the complete technology tree of the Small Star Sector Advanced Civilization." After the envoy finished speaking, a huge storage device appeared out of thin air on the ground, making the leader of Linglong star in disbelief. The complete technology tree of the Small Star Sector Advanced Civilization had been obtained so easily.
"Chief of Linglong, after obtaining this technology tree, you can build complete advanced warships in Small Star Region on your own, and you will no longer be held hostage by those Small Star Sector Civilization. However, in the first stage, you will conduct secret research, analysis, and complete all theoretical accumulation. Everything can only be carried out secretly in the laboratory. Currently, the key components of the warships are small in size, and you can secretly build them in large quantities in the underground laboratory. Once you have accumulated enough, you can replace the components provided by other Small Star Sector Civilization all at once."
"Understood. Although we can't manufacture those things, we know that those components have backdoors, and the real control of the warship is not in our hands."
"This is what they've been using you for all along. Alright, Queen Linglong, I should go now. Goodbye."
After the envoy finished speaking, he climbed into a small spaceship, only half of which appeared in the three-dimensional universe, and then disappeared into the room of the Linglong leader, heading to the next civilization.
This scene was happening simultaneously around the leaders of ten thousand civilizations. Although the envoys' stories differed greatly, the success rate was close to one hundred percent. They could obtain the technology trees of Small Star Sector Advanced Civilization without paying any price. No civilization would refuse such a good thing. A few leaders of civilizations were extremely upright and refused Li Shun's special envoy, but they had some of their memories erased and did not remember that Li Shun's special envoy had ever come.
While most civilizations did not believe the whitewashing claims made by these special envoys, they had to admire their rhetoric. Even if they didn't believe it, they no longer harbored hatred towards Li Shun and even felt a trace of sympathy. By the time the defensive line had advanced to ten thousand light-years, all of Li Shun's special envoys had completed their missions without being exposed.
Only the civilization envoys within Hu Yu's territory remained uninfiltrated, as the Conqueror constantly patrolled the fourth dimension, deterring the envoys from venturing in. However, in the peripheral areas, the envoys had already established several Fortress Civilization, through which the technology trees would gradually permeate other Fortress Civilization.
All of this was kept completely in the dark by the Small Star Sector Civilization. All the civilizations were busy with the war on the front lines, and no one expected Li Shun to pull this stunt.
Hu Yu was also pondering the future of these Small Star Sector Civilization. The development of civilizations requires sufficient territory, and the space needed by Small Star Sector Civilization civilizations is often hundreds or thousands of light-years. The galaxy simply does not have enough space to support the survival and development of so many Small Star Sector Civilization.
Currently, these cultivated Small Star Sector Civilization have real Small Star Region providing them with resources and planet creation. Once the war ends, the resource supply will inevitably be cut off. In order to survive and develop, these Small Star Sector Civilization will have no choice but to extract resources from the Milky Way. Although the Milky Way has a large number of planets, not every planet is suitable for terraforming. At that time, various conflicts will inevitably break out for resources and space.
Although they have now conquered a large territory, the space is still very crowded in the face of two million Small Star Sector Civilization. It's like a room that could only accommodate two people, but now ten or twenty people have come in. If they move around a little, they will bump into other people, and even talking will disturb others.
Hu Yu's idea is to expand the galaxy's range. There are many binary and multi-star systems in the galaxy. He plans to convert all of these into single-star systems, move the excess stars to the outer reaches of the galaxy, and then extract energy from the fourth dimension to synthesize planets for these civilizations to use as inhabitants.
For the sake of stability in the galaxy, the number of fleets of these civilizations must be strictly controlled, and the entire galaxy should exist in the form of an alliance. Although this is difficult, as the gap between civilizations is huge and it is extremely difficult to get one civilization to fully trust another, at least a galaxy police fleet should be established to maintain peace in the entire galaxy.
However, all of this was just Hu Yu's speculation. These civilizations were created by Great Star Region Advanced Civilization, and they were the ones who had to clean up the mess. Hu Yu didn't want to bother being the good guy. He hadn't even resolved his own issues, so he had no energy to deal with these things. As long as the Star Ring Alliance didn't cause any problems, that was enough for him.
The defensive line quickly advanced to the Matter River. Once there, the swarm no longer scattered and fled, but regrouped to fight the fleet. The swarm was reduced by 70%, and the civilization fleet was also reduced by half. Now that the swarm has regrouped, the two sides are evenly matched, with a buffer zone of more than 100 light-years in between.
Several overconfident civilization fleets attempted to advance further, but after traveling less than 50 light-years, billions of warships were instantly destroyed by a massive energy band stretching one light-year in length. Clearly, this was the work of the Insect Emperor, which terrified all the civilization fleets, who dared not advance even an inch further.
The fleet didn't advance further, and the Insect Emperor didn't make a move. The Matter River remained quiet, with neither fleets nor insects around. Entering the Matter River was now impossible; the Insect Emperor was undoubtedly keeping a close eye on everything happening here.
Hu Yu has ordered the fleet to begin transporting stars to the defensive line and converting them into neutron stars to establish a new four-dimensional defense line. In fact, black holes would be more effective for defense, but their gravity is too strong, and the fleet cannot control their movement. Therefore, the only option is to create neutron stars.
With the efforts of countless warships, the Neutron Star Defense Line was quickly re-established. The neutron stars were very close together, and the entire defense line was extremely dense with them. The space within the Neutron Star Defense Line was quite chaotic, so the Zerg swarm could only slow down and move slowly if it wanted to pass through the Neutron Star Defense Line, giving the fleet enough reaction time.
As long as the swarm doesn't launch a full-scale attack, the defensive line won't need so many fleets anymore. However, Hu Yu didn't order these fleets to retreat. On the contrary, all the warships at the bases still need to support the front. Firstly, this would consolidate the defensive line, and secondly, Hu Yu was worried that if these fleets were all concentrated at the bases, they would clash.
It is easy to share hardship, but difficult to share wealth. The same is true between civilizations. The defense line has been established for less than a century and there are already signs of conflict. More than a dozen real Small Star Sector Civilization have expressed to Hu Yu that their territories cannot accommodate so many civilizations and wish to send them away.
Faced with this demand, Hu Yu could only say that the defense line was not yet stable and that he needed to wait for further instructions from the Great Star Region Advanced Civilization. Meanwhile, some of the Small Star Sector Civilization that had been cultivated were already eager to set up camp in the airspace they had just conquered. Some of these civilizations were originally from the Insect Zone and hoped to rebuild their homes, while others were simply grabbing territory.
