Chapter 103 The Great Wall of Space

   While Lu Yu was listening to No. 7's explanation, a special alarm sounded at Base Zero on Blue Star.

The hosts of almost all projects immediately put down their affairs and came to the conference hall of Base Zero. Many professors who were too late to come back and many indescribable Huaguo bosses were participating remotely through virtual reality. .

   "A fleet traveling at the speed of light is heading towards the solar system?"

   "Arrived in 15 years!?"

  As the information was pushed to the projection screen in front of everyone, after a moment of silence, the entire chamber was filled with buzzing discussions.

  Everyone knows that the humans of Blue Star will encounter alien civilizations sooner or later, but they didn't expect this day to come so suddenly.

   "Advance at the speed of light. Does it mean that the technological level of this fleet has only reached level four?"

   "After all, the fifth-level civilization already has a curvature engine, and it can move forward in a faster and more efficient way!"

  An expert sitting in the front row was the first to ask the question that everyone was most concerned about—what level of civilization is the fleet that is about to arrive in the solar system!

  With base zero mastering the fourth-level civilization database, human beings have begun to have a relatively preliminary understanding of the fourth-level civilization, but the fifth-level civilization.

   Recalling the weapons Lu Yu encountered in the Dyson ball civilization, antimatter missiles, gravitational bombs, etc.

  The opponent only needs to drop these two known weapons on the sun. It is no exaggeration to say that if this fleet is at the technological level of a fifth-level civilization, then human beings have no room for resistance.

  When I watched the silver star kill all directions from a distance, I didn’t have any intuitive feeling for the fifth-level civilization. Now I feel like eating a melon on my own head, and I suddenly realize that the big melon is so heavy.

  "All the information now is only obtained from the system's mission prompts. The most important thing for us now is to determine which direction this space fleet is coming from!"

   "Only then can we have a real basis to judge that it is a level civilization, and then extend to their purpose of coming to Blue Star!"

   After Professor Mao, who presided over the meeting, answered this question, the conference hall was buzzing again. The news of the alien civilization's visit is still too shocking for human beings today.

  Now human civilization can be regarded as the early stage of the second level at best, and there is still a long time to go before the space elevator is built like the Horn Tribe, and the later stage of the second level civilization of the space city.

   If it takes another hundred years, or even three hundred years, for this space fleet to arrive, they will not be so passive anymore.

   "Silver Star! If the Silver Star is here, our initiative will be greatly increased."

   "Can Lu Yu return to Blue Star within fifteen years?"

   Someone soon thought of the strongest combat power of human beings. As soon as he said [Silver Star], many people's expressions of worry and panic immediately eased a lot, as if they had found their spiritual support again.

  “.”

  Professor Mao was silent for a moment before speaking: "We have completed the basic proofreading of the star map obtained from the Qing family, and a fact that we have to admit is before us."

   "The galaxy cluster above does not match any of the galaxies that we humans have observed. The scale of the universe is far wider than the 93 billion light-years that we humans can currently observe."

"The Silver Star has been space hopping in the universe for nearly 6 years, and the exploration of the space region is likely to be just a drop in the ocean. Given another 15 years, more than 40,000 jumps can really find the way to return to the blue star." Star Road?"

   "Compatriots, please don't take chances!"

  If it was in the past, when human beings failed to break through controllable nuclear fusion, star-level civilizations came as soon as they came. Humans can't even grasp the moon, so can they prevent others from reaching the solar system?

   Moreover, a mere first-level civilization, a star-level civilization may not look down on humans on Blue Star!

  At that time, what if an alien civilization is discovered? I can only close my eyes and act like an ostrich, hoping that people are just passing by.

  Pray that the solar system is just the most common type among the thousands of star systems, and there must be no scarce resources that make the star-level civilization move the idea of ​​​​bringing [democracy and freedom] to the indigenous civilization.

   But now it's different.

  Humans have Lu Yu, so they have a window to observe the civilization of the universe, and thus the current No. 0 base was born.

It has the technology database of the fourth-level civilization, and now it is continuously supplementing the scientific and technological achievements of the third-level civilization from the lizard civilization. Humans really just lack time, and they can’t only entrust the survival of civilization to the high-level civilization [ Well-intentioned] weak human beings.

  Moreover, the planetary civilizations, the Horn Race, and the Lizard Civilization that humans have seen from Lu Yu's journey seem to be quite miserable.

  One was simply wiped out of the whole family, and the other was trapped to death in the black domain.

  The civilization stage of the universe seems to be accessible only to star-level civilizations, and planetary-level civilizations can only be the red carpet on the stage for characters to step on.

   It is precisely because of this that everyone has to be cautious about the information revealed by the system task prompt.

   "The story of the Horn Clan is still vivid!"

   "We must not allow human beings to repeat the same mistakes!"

   "Even if the civilizations in the universe are not hunters with guns, we cannot pin the safety of human beings on the existence of another civilization [goodwill]."

  Everyone who can enter the conference hall is aware of the situation of the civilization of the universe. The fragility of the planetary civilization is something that everyone can see after opening their eyes to the universe.

  Any planetary-level disaster, such as planetary impact, such as environmental sudden changes caused by stellar activities, can change the progress of planetary-level civilization into another look.

  Even the evolution of a large celestial body a few light years away or dozens of light years away can affect or even destroy a planetary civilization. This is the helplessness that can only be limited to one star field.

  When it comes to star-level civilizations, the so-called mother star is no longer needed. Wherever the spaceship reaches, the mother star can be recreated everywhere. As long as there are enough spaceships, the entire civilization can survive in space.

  Human beings could have reached this level of civilization without any problems. They thought they could give enough time to civilization, but sudden changes disrupted all plans.

   "Since it is moving at the speed of light, it means that the fleet will slow down accordingly before approaching the solar system. As long as we can lock the direction in which they are approaching, fifteen years is enough for us to do something!"

   "We propose that no matter what purpose they come to the solar system, they must be blocked in the Oort Nebula!"

   "In the next fifteen years, we will build a space wall in the Kuiper belt to guard the blue star and guard our only homeland!"

  【The Great Space Wall Project】

  Professor Mao, who presided over the meeting, on the huge projection screen behind him, displayed these few large characters that seemed to carry the survival and decline of human civilization fifteen years later.
