The evolution of insect swarms from XNUMX million years ago

Chapter 226: Foreigner
The defense system took shape bit by bit, gradually surrounding the outer solar system, and because it was well concealed in the visible and infrared bands, Lin Yi would not even be able to see the existence of these structures if it were not for the connection between the synaptic structures in space.

According to speculation, in space, something like active radar is equivalent to raising your hands in the crowd, saying a "Declaration of Independence" and shouting that everyone should look at me. Under normal circumstances, a combat spacecraft will not easily turn on its active radar before it is discovered.

Without the use of active radar, unless more advanced detection methods such as gravitational waves are mastered, it is almost impossible to discover these structures hidden in the dark.

In turn, these detectors can monitor the outer solar system using accompanying passive reception observation systems in the infrared, optical or electromagnetic bands to identify the locations of unknown entities that may be approaching.

More and more space creatures and detectors are produced and placed in predetermined orbits, continuing to form part of a complete defense system.

The answer to the question of whether extraterrestrial life and civilization exists has been affirmatively answered with the emergence of Bao. And, their existence may be closer than imagined.

In just one small solar system, three civilizations were born - Ba'ao, Lin Yi's nest, and later generations of humans. In the long history of evolution, the emergence of intelligent creatures, no matter how low the probability, will be eliminated for a long time. enlarge.

The existence of unknown intervenors proves that civilizations with a higher degree of development once existed - although from the severely damaged wreckage of those space stations on the earth, their specific level of civilization development cannot be seen. It can only be based on Bao's Describe and speculate on its approximate level.

Bao and the Unknown Intervenor at their peak should both have curvature navigation or other means of faster-than-light navigation. In terms of basic theoretical science alone, they are much better than the current Lin Yi.

The prosperous Bao did not leave much useful data due to its large-scale use of organic structures. Lin Yi was unable to speculate in detail, and it was impossible to talk about reverse engineering.

But soon, this hard-won peace was ruthlessly broken by the intruder.

As for the unknown intervenor, Lin Yi knew even less about him. He only knew that there was a high probability that he was no longer active in this area, perhaps because of his death, or perhaps for some other reason. In short, he did not even perform the most basic steps of destroying corpses and exterminating traces. , disappeared forever.

However, nothing was discovered for a long time. Everything remained calm for a long time. There were no imaginary alien spacecrafts. Except for the occasional comet passing by, there was nothing that moved.

As time continues to pass, the defense system gradually takes shape, and Lin Yi's expansion operations on Mars and the asteroid belt continue. At the same time, the detector is also constantly monitoring the situation in the outer solar system.

Of course, Lin Yi wished he could stay calm like this forever, even if the defense system he built by consuming a lot of materials didn't work.

Without warning, an extremely strong heat signal suddenly appeared in the infrared field of vision at the edge of the solar system, conspicuous like a bright light in the dead and cold cosmic environment.

Lin Yi was sure that he had read it correctly. A second ago, the space was empty. In an instant, the infrared signal appeared and started moving directly, without any acceleration time in between.

Recently, the detector structure equipped with the bio-optical space telescope immediately set its sights on the space where the infrared band signal is found, capturing possible reflected signals. After some comparison and observation, he filtered out unusual signals from the vast background of the universe - they were several specially shaped outlines. It was obvious at a glance that they were not naturally formed.

After zooming in as much as possible, Lin Yi could clearly see their appearance - the overall shape was roughly rugby-shaped, with symmetrically arranged prismatic and hemispherical rounded protrusions all over the surface, but they did not appear messy, but made them more prominent. Very elegant.

At their tails, a large number of infrared signals are emitted from several special structures. The combination of various characteristics makes them clearly man-made spacecrafts, and their technological level must be more advanced than Lin Yi's current space creatures.

A simple comparison of the carrot-shaped appearance of the space creature and the structure of the other side shows that the technological level of the two sides has widened the gap. As for the specific gap, Lin Yi is not sure.

Just judging from the opponent's current performance, its technology did not reach the level of causing a dimensionality reduction blow to Lin Yi, but its sudden appearance really made Lin Yi a little confused - it was clearly a method of traveling at the speed of light.

The most realistic method that Lin Yi can think of for traveling at super-light speed is the curvature engine, but for this thing, he only knows the name, the specific principle, and how it looks to the outside world when it is running. .

But one thing that is certain is that it will definitely leave traces. No matter what kind of traces it is, it will not appear out of thin air outside the sun's gravity well like it does now.

Moreover, the principle of the curvature engine seems to be related to gravity and space, which means that if a civilization has a curvature engine, it will inevitably have detection methods related to gravitational waves. This means that Lin Yi’s current detectors and space creatures will inevitably will also be exposed.

It can be said that if the opponent really has supporting detection methods and is hostile, then the moment they appear, they will attack the nearest detector structure - the attack methods that should be mastered theoretically at this level are not available at this level. At this distance, discovery means destruction, which is not empty talk.

And if the other party comes with good intentions, they can broadcast a large number of signals to explain their intentions at the moment of discovery, so as to avoid unnecessary misunderstandings - it is weird in every sense.

The opponent's detection system has not been turned on yet, which makes this speculation even more untenable. When entering an unfamiliar environment, the detection system must be turned on as soon as possible to understand the environment to prevent a sneak attack.

At this time, Lin Yi's consciousness was running rapidly, and various possibilities flashed through his consciousness, and then were quickly ruled out - all kinds of evidence showed that the other party probably did not discover the disguised detector structure.

This means that the opponent's technological level in detection and other aspects is probably not as high as Lin Yi imagined, and does not match the technological level in navigation - but it is even weirder, as if an advanced military transport plane has landed , but what came out of the cabin was a group of primitive people holding spears and clubs, who were generally disobedient.

However, the sudden appearance of the other party without warning still made Lin Yi remain deeply vigilant. At least, in a short period of time, he did not dare to act rashly and continued to hide, waiting for further results.
