The defeat of the Lukka Star fleet once did not receive the effect that Xiao Yu expected, but reaped fruitful fruits in the rest of the directions.

With the help of these nearly 2,000 Luka spaceships, as well as these tens of thousands of Luka stars, Xiao Yu will be able to quickly upgrade to a third-level civilization.

But Xiao Yu was still very resolute and ruled out the plan to stay in Tianyuan IV and continue to fight against Luka's fleet. Because Luca's fleet will have at least two big killers that surpass the third-level civilization, and in a short period of time, he has not improved the performance of the spaceship to the same level as the Lucca civilization.

This meant that it was imperative to escape, and now it was up to the question of how to escape without being tracked by Luka's fleet.

Xiao Yu already had several plans in his mind, such as trying his best to eliminate the traces of his spaceship's launch, not letting the Luka civilization detect it, or creating an illusion to confuse the Luka fleet and so on.

During the period of returning to the four star systems of the Aerospace Garden, Xiao Yu obtained a large amount of technology and basic theories from the Lucca Star, and these knowledge were quickly digested by Xiao Yu and integrated into his own theoretical system.

With the help of this knowledge, Xiao Yu quickly constructed the blueprint for the construction of the new spaceship, and now, after returning to Tianyuan IV, Xiao Yu can start the construction of the new spaceship.

The new ship will have an energy shield system that is not weaker than Luka's, and in addition, the maneuverability and attack power will also be greatly improved.

The most important thing is the gain from the theoretical system. The third-level civilization has already researched a new type of energy source, which is beyond nuclear fusion, that is, energy is obtained through the decay of the proton-neutron stage. To put it simply, it is the formation of new protons or neutrons through the recombination of quarks, in which the heavy elements will rapidly decay into light elements, and in this process, at least 50% of the mass is converted into energy.

Xiao Yu remembers very well that the explosion of the earth is because under the influence of some unknown force, the iron and nickel elements in the earth's core decay into hydrogen and helium, releasing a large amount of energy, and the earth was directly shattered. This is a material reaction that comprehensively surpasses nuclear fission and nuclear fusion. Inspired by the theoretical system of Lucca civilization, Xiao Yu preliminarily determined the excitation conditions for this material reaction, and its large-scale application is expected to be realized within a thousand years.

In addition, Xiao Yu also has a general understanding of the situation of various civilizations in the galaxy.

During the two-and-a-half-month return journey, Xiao Yu asked a question to the Lucca civilization: "Destroying the rest of the civilizations can improve your own civilization luck, is this saying correct?" ”

Luca One replied: "Basically correct. To be precise, it should be that destroying the creatures of other civilizations can increase the luck of your own civilization. In other words, even if you only destroy one creature from the rest of the civilizations, you can get a certain increase in the luck of your own civilization. The increase is related to the technological level of the destroyed civilization. But luck, or luck, is not accurate. In your technology, there is a theory called quantum mechanics, in which a quantum state in a superposition state is indeterminate. ”

Xiao Yu knows that in the principle of quantum superposition, the most famous guess is the Schrödinger cat equation. To put it simply, until you look up to see if the moon exists, the moon is uncertain whether it exists or not, it may or may not exist, and there is a 50% probability of each of the two possibilities, that is, the moon is in a superposition of the two states of 'being' and 'non-existence' at this moment, it is both present and non-existent. Only the moment you look up can you decide whether the moon exists or not, and its state can be determined.

According to quantum mechanics, whether the moon exists or not at this moment is 'decided' by you at the moment you start to observe.

The process by which the state is determined is called 'quantum collapse'.

Xiao Yu nodded, indicating that he understood, but Xiao Yu then raised a new question: "What does this have to do with luck, or luck?" ”

Luca One replied: "It has a lot to do with it. Under normal circumstances, the moon - well, the name is beautiful, and the probability of its existence or not, each accounts for fifty percent. But make an assumption that if you want the moon to exist, there is always a fifty percent chance of it being there before you destroy one of the rest of the civilized creatures, no matter what you expect. But after you destroy a creature from the rest of the civilization and you expect it to exist, the chance of its existence becomes fifty points 1. In short, that's it. ”

Xiao Yu suddenly realized.

Xiao Yu completely understood. For example, if Xiao Yu hopes that there is a powerful alien fleet in front of him that completely obeys his orders, before destroying an alien civilization, the probability of its existence and non-existence is fifty percent, but after Xiao Yu destroys an alien civilization, the probability of its existence may become fifty-one percent.

Xiao Yu sighed and continued to ask, "Weishenme? Do you know why? ”

Lukka One shook his head: "I don't know. ”

Each of Xiao Yu's questions was concluded by asking thousands of Lukka people who were isolated from each other and comparing the results with Lukka One's answers. From this, Xiao Yu was sure that Luca One was not lying.

"You civilization, what do you guess about this?"

"This is what we spent 10,000 alliance contribution points in exchange. We only know the conclusions, not the reasons. Maybe...... We are all a piece of data, and there is some detached, unknowable being watching us in the shadows, taking pleasure in making us fight each other. Luca One replied.

Xiao Yu shook his head. This answer is basically equivalent to not saying anything. Xiao Yu gave up his interest in continuing to dwell on this issue, and instead raised a new question.

"What kind of social structure is the so-called Guardian Alliance?"

Lukka One replied, "The Guardian Alliance is an alliance formed under the leadership of a powerful civilization called the Guardian Civilization, and under the alliance, there are tens of thousands of different civilizations. The Guardian Alliance, which was formed primarily to fight against the Sweepers. Within the Guardian Alliance, low-level civilizations can earn Alliance Contribution Points by doing various tasks, and through Alliance Contribution Points, they can be exchanged for various rewards such as technology and super weapons. ”

"It seems that my guess is right, this Guardian Alliance is indeed a powerful civilization-led alliance." Xiao Yu thought silently and continued to ask, "What is a sweeper?" ”

"The Sweepers are another civilization. However, this civilization is bloodthirsty and tyrannical, and as long as the civilization it discovers, it basically cannot escape the fate of extinction. Our Lucca civilization was summoned by the Guardian Alliance 20,000 years ago and joined the Guardian Alliance, so as to avoid the fate of being wiped out by the Sweepers. ”

"The sweepers wiped out the rest of the civilizations, no doubt for the sake of improving their own civilization luck, so I have a doubt, will the guardian civilization choose to protect the weak civilization instead of directly destroying it? Guardian Civilization ...... Is there really such a high morality? Xiao Yu asked.

Luca One was silent for a long time before shaking his head: "Maybe what you said is right. We only have this one explanation. There is no other explanation than the belief that the Guardian civilization is truly morally high. ”

Xiao Yu scoffed at this. However, Xiao Yu did not dwell on this question, but asked another question.

"Tens of thousands of weak civilizations...... What is your role within the Guardian Alliance? ”

Luca One was quick to reply: "There are a lot of roles that can be played. Logistics supply, material transportation, battleship maintenance, intelligence gathering and other tasks. As you may know, our Lucca civilization once rented a teardrop-shaped probe to collect all kinds of intelligence in the third star field, which is part of intelligence gathering. The weak civilizations under the command of the Guardian Civilization exchange contribution points through various tasks, and use the contribution points in exchange for technology and the protection of the Guardian civilization. Or, if there is an extremely powerful civilization, it can also directly assist the Guardian civilization against the Sweeper civilization, and the acquisition of contribution points for this kind of task is extremely amazing. However, in order to participate in the war between the Guardians and the Sweepers, you also need to be at least a level 6 primary civilization. ”

"Guardian Civilization...... Which one is more powerful, or the Sweeper civilization? What level of civilization are they? ”

"They are all sixth-level advanced civilizations. In the Morcas, uh, galaxy, the Guardian civilization and the Sweeper civilization are the two most powerful civilizations. Level 7 and above civilizations belong to legendary existences, and I don't know how many billions of years have not appeared in the galaxy, and even, level 7 and above civilizations are hard to say whether they exist in the entire universe. ”

Lukka One paused and continued, "In conventional combat power, the Guardian civilization has the upper hand. In high-end combat power, the Sweeper civilization has the advantage. Because the Sweeper civilization has an ultimate war fortress, the Neutron Warstar. So overall, it's still the Guardian civilization that is at a disadvantage. ”

"Neutron Battlestar?!" Xiao Yu asked in surprise.

"Yes, Neutron Battlestar." Lukka One replied earnestly, "The Sweeper civilization doesn't know where to get the technology, they hollowed out a neutron star and transformed it into a war fortress. This is almost indestructible, at least, the Guardian civilization has tried for tens of millions of years, but has not found a way to destroy the Neutron Warstar. It is precisely with the Neutron Warstar, the ultimate war fortress, that the Sweeper civilization has crushed the Guardian Alliance. ”

Xiao Yu's heart was agitated, and he could hardly control himself.

"Neutron Battlestar! Neutron stars can also be used as war fortresses! I don't know, when will I get to that point? ”
