The black patches rapidly enlarged against the background of the silvery-white planetary rings, spreading out at a speed visible to the naked eye until they became a circle like a black hole. After a black spot stopped expanding, the task force's spacecraft launched dozens of more of these unidentified objects, which were attached to the edge of the four galaxies of Tianhua, and like the first one, they all spread to a certain size and then stopped changing, these black unidentified patches were like dozens of pitch-black, neatly arranged mirrors, aimed at the yellow-white star in the center of the galaxy from all directions.

"Nephi! I ask to talk to the Alliance! This is not what was agreed upon. Mark yelled at the communicator, his hands trembling slightly, he really didn't expect such a thing to happen at this juncture.

"Don't be nervous, it's just an insurance, it's in the agreement, and we promise that until the assessment is explained, the earth will be under the protection of the alliance during this period." Neffei's voice came from the communicator, and the voice of the flesh pillar creature was still as usual, but Mark could hear the smell of conspiracy in his tone.

"Insurance? Is it for you, or for us? Mark sneered.

"It's an insurance for both of us, this is also the order given to me by the chairman, I just do things according to the rules, I'll tell you now......" I don't know if it's because of the influence of these black spots, Nefei's voice became shrill and weird: "These black spots are low-speed barrier singularities, they are currently in a suppressed state, the alliance will regularly send special signals to reset their internal countdown, as long as the timer has not returned to zero, it will not start, unless you have not completed the assessment of the alliance in a hundred years, That's when it will be activated. ”

"What if it starts?" Mark asked.

"When the next launch is complete, this galaxy will be surrounded by one hundred and sixty-five low-light singularities, and when they are detonated at the same time, the low-light speed barriers they emit will be connected together, and this galaxy will ......"

"Will it be completely enveloped?" Mark said the second half of what he was going to say.

"Yes, at that time, the galaxy will be cut off from the low speed of light barrier, all contact with the outside world will be cut off, and human civilization will be completely sealed in it, which is not only a punishment for failing the assessment, but also a kind of protection for you...... Civilizations that can't even reach the normal speed of the universe can't make efficient use of the matter in the universe, and can't establish effective connections with other civilizations, for you, the universe is too dangerous, and it is lucky to be closed, and if you encounter a dangerous race in the universe, your fate will be even worse. ”

"There won't be a day, we're going to break it all." Mark's tone was calm and resolute.

"Good luck with that, I hope they never start, if there is a day when I will activate it myself, to be honest, I like you quite a lot, and if there is one more carbon-based race in the alliance, it will be good for us too." Nefi said.

"So, do you have any hints for us?"

"All I can tell you is not to try to get close to those singularities, it takes a higher level of technology to remove them than to travel at the speed of light, and it is impossible to get technology from them, and if the singularity is detonated because of you, we are not responsible." Nefi warned.

The whole process of planting the singularity took less than two days, but the shadow it left behind will last for a long time, spreading and spreading in human society, becoming a terrifying existence like a hanging knife, and the truth of the shady curtain was soon revealed to cause an uproar among the people.

More people feel panic, shrouded in this inch of the world, can never escape what a desperate situation, most of them are very hopeless about the speed of light navigation technology, thinking that the probability of developing it is really slim, and now there are more threats to this layer, which makes everyone's shoulders a little heavier, they are now not only facing a harsh assessment, but also a big gamble, betting on the future and fate of the entire human civilization.

The research of lightspeed technology has also been carried out soon, and the newly formed five regions of the earth have worked together to abandon contradictions and integrate research resources, and now that the race has begun, they have no time to waste, more than a hundred black curtains are like more than a hundred ticking timing**, how can people feel at ease when they hang over their heads.

There are negative people and there are positive people, and some people think that this is a lucky thing, just like the flesh pillar creature said, for the current human beings, the universe is too dangerous, take this contact incident as an example, human beings themselves have not done anything wrong, but they have no intention of being involved in it, which almost destroyed human civilization, the low light speed barrier means that human beings cannot easily leave, but people outside can't see inside, and it's not so easy to get in, Dangerous civilizations passing by would not venture into such a dangerous area.

Besides, being trapped in it doesn't mean that you can't get out again, the resources available on this planet are far more than the solar system, the energy contained in the four stars is more than a hundred times that of the sun, and the surrounding giant planet is similar in size to Saturn, it stands to reason that it is very dangerous to be so close, the earth is likely to be captured by the gravity of the giant planet, and it is torn apart by the giant ring, but the current position of the earth is very unscientific, and the auxiliary gravitational field left by the alliance is still in effect, which leads to the fact that although the earth is very close to the giant planet, but not to be caught by it. A large number of metal minerals can be collected from the giant planet's ring, and there are no less than a hundred small moons around the giant planet, and if nothing else, there are many liquid planets like Ganymede, which contain large quantities of methane or ethane fuel that can be directly used.

No matter from which point of view, human beings in this galaxy are much more nourished than in the solar system, even if they are closed by barriers, the resources in this galaxy are enough for human beings, maybe hundreds of years, maybe thousands of years, or even tens of thousands of years, there will be a day when human beings will develop here to the limit of what resources can bear, then there will be tens of thousands of large space cities like Star City in the galaxy, maybe you can build a simple Dyson sphere, it doesn't need to be too efficient, As long as a small fraction of the stellar energy can be absorbed, it will be enough to keep the entire human world running, and by that time, it may not be impossible for humans to break through this barrier.

In the eyes of this faction, the shady curtain is not an obstacle to civilization, but an excellent opportunity for human beings to better recuperate here, and they have been frightened by advanced civilizations like the Alliance, and they can't wait to hide in the dark now.
