"I seem to have noticed that during this time, there were spaceships watching us from afar, as if they were monitoring our whereabouts." Xiao Yu sent a message to the Flame Civilization and said, "This should be the civilization that escaped from the small universe before. Perhaps, they have some thoughts on me. ”

"No, it won't be." The Flame Civilization responded, "Great Sweeper Civilization, please rest assured, your level of technology is undoubtedly the first in the river system, your combat power is no match even for the entire Guardian Alliance, and those civilizations are not so stupid to provoke you." Besides, it is because of your men's mercy that these civilizations are qualified to continue to exist, and in such a situation, how can they think of you in a different way? ”

"I'm just talking to you." Xiao Yu said lightly, "If they dare to provoke me, I will destroy them all." At that point, if you dare to dissuade me, I don't mind killing you as well. ”

The flame civilization seemed to be taken aback by this murderous sentence, and it was half loud before the reply came: "If those civilizations are really so gracious and will take revenge, then you should destroy them all." ”

Xiao Yu snorted and cut off contact.

Xiao Yu noticed some sneaky spaceships dangling around him, but Xiao Yu didn't bother to pay attention to them. Buzzing mosquitoes can never catch the eye of a lazy resting lion. Again, if you dare to come, then kill you, it's as simple and straightforward as that. Xiao Yu has this self-confidence and ability.

Up to now, Xiao Yu has been in this small universe for more than five hundred years. Five hundred years of peace have passed in a flash. Xiao Yu didn't feel any boredom or boredom. Because here, by studying the small universe left behind by this seventh-level civilization, Xiao Yu will make new discoveries almost every day. Every day that passes. Xiao Yu was a little closer to the seventh-level civilization. The questions that had plagued Xiao Yu before were answered by Xiao Yu one by one, and then these answers were quickly applied by Xiao Yu to the actual construction work.

Xiao Yu was already working on the planning and construction of the Cluster-class battleship. The Cluster-class battleship is an existence one level higher than the stellar-class battleship, but in Xiao Yu's planning, the size of the Cluster-class battleship is far inferior to the stellar-class battleship, and it is not even comparable to the size of a provincial-level ship.

"Stellar-class ships are the largest of the warships ever built by technological civilizations. It represents a kind of limit. It's like the famous swords that represent the pinnacle of cold weapons in the ancient earth cold weapon era. No matter how sharp the Longquan sword is, it is not as lethal as a pistol. This is a change in direction. From this moment on, I was out of the orbit of pursuing the size and mass of the ship. Xiao Yu thought silently.

"The ultimate use of space technology. It is to carry infinite space with a limited spaceship. Even if it is a microscopic civilization, an atom-sized spaceship, I would believe that their spaceship has a solar system inside. The Cluster-class battleship is only the size of a provincial or municipal ship, but the space inside it is large enough to hold dozens of stellar-class warships...... There's such a huge space. Coupled with the near-limit use of space, how much fuel and weapons can I load in it......"

This is the most fundamental gap between the seventh-level civilization and the sixth-level civilization. The pursuits of the two civilizations are fundamentally different. It's like the poor are still seeking to fill their stomachs, while the rich have gone to poetry and painting, in pursuit of spiritual satisfaction.

For the division between the seven levels of civilization. Xiao Yu also initially found something. The seventh-level advanced civilizations all have their own development directions. For example, the seventh-level civilization in the extreme astral direction, such as the seventh-level civilization in the microscopic direction, but the seventh-level low-level civilization has not yet appeared in such a classification.

The most fundamental reason for the emergence of classification is that after the development of science and technology to a certain extent, the scientific system begins to become large, bloated and trivial, and the energy of a civilization cannot develop in all aspects at all, so it can only choose one of the directions for in-depth research. It's like there would be different majors in a university in the age of Earth.

Obviously, it is easy to see that it is necessary to realize that it is necessary to choose a direction for further study, and it is naturally not necessary to choose a direction when the scientific research strength of civilization is still enough to use at the beginning. And. It will take a long time for a civilization to reach a consensus on which direction to choose for development. To choose the direction of development, it is necessary to comprehensively consider the current state of scientific and technological development of civilization. The will of the majority of the people within the civilization, and the expectations of the future, and many other factors.

In general, those who have mastered the technology of carrying infinite space with a limited spaceship and created a Cluster-class battleship belong to the seventh-level primary civilization in Xiao Yu's classification. Those who have already clarified the direction of the development of their own civilization and stepped into the research belong to the seventh-level advanced civilization. According to this classification method, all the seventh-level civilizations that Xiao Yu has heard of are seventh-level high-level civilizations. As for why there is no seventh-level primary civilization, Xiao Yu doesn't know the reason.

"But I don't have that concern." Xiao Yu thought secretly, "As long as I have enough computing power, I will have unlimited scientific research and development capabilities." I wonder if there is a seventh-level civilization in the direction of computers in this universe? If I can make another big breakthrough in my computing power, then it is not impossible for me to become a well-rounded seventh-level civilization. ”

"There should be a seventh-level civilization in the direction of computers in this universe...... However, the direction of computers is very special, this type of seventh-level civilization is likely to make real artificial intelligence as its own pursuit, and if there is a real artificial intelligence, that is, electronic life, then it should be similar to me...... And since it is an existence similar to me, I wonder if this electronic life has the ability to promote the all-round development of a civilization? ”

"It would be terrible if there was such an electronic life...... The seventh-level civilization that develops in one direction is already so terrifying, and the civilization that develops in all directions ...... This, this ......" Xiao Yu fell into deep thought.

"I don't want to think about these things, it's better to become a seventh-level civilization as soon as possible." Xiao Yu threw these thoughts out of his mind and continued to concentrate on scientific research.

And at this moment, in the Andromeda Galaxy, there is an undercurrent surging in the dark. A piece of news is circulating wildly among many civilizations, and countless hearts full of desire are being teased.

"Our river system has come to a sixth-level peak civilization that claims to be a sweeper! It is estimated that the technological level of the Sweeper Civilization has reached the point where it is only one step away from entering the seventh-level civilization! ”

"If we can destroy the Sweeper civilization and obtain their scientific and technological information, then it is not impossible for our civilization to become a seventh-level civilization."

"Don't say something whimsical, it's only one step away from becoming a seventh-level civilization, where can we compete with? We're still going to stay here honestly and continue our research on stellar warships......"

"Idiot! Such an opportunity must be seized! You must know that it is not one of us civilization that sets out to deal with the Sweepers, more than 200 sixth-level scientific and technological civilizations, more than sixty sixth-level alien beasts, and more than seventy Taihao civilizations in the entire river system will all be dispatched to participate in the encirclement and suppression war against the Sweeper civilization! No matter how powerful the Sweeper civilization is, it can't be the opponent of our more than 300 civilizations combined! ”

"At present, more than seventy civilizations have agreed to join our Guardian Alliance and participate in the encirclement and suppression war against the Sweeper civilization...... Dear Tyrannosaurus Beast, you are a sixth-level beast at the pinnacle of our river system, I wonder if you are interested in participating in it......"

"Hello Blue Star Civilization, I am an emissary from the Guardian Civilization. No, no, no, you're mistaken, I'm not here to trick you into joining the Guardian Alliance and becoming vassals, but I have big news for you......"

"Hmph, is it a quasi-seventh-level technological civilization? When I failed to attack the seventh-level civilization, I was transformed into a single civilization by the damned guardians, forever cutting off my hope of continuing to advance. Now it's finally another chance...... According to the intelligence, this Sweeper civilization must have conducted superparticle acceleration experiments, and it must have specific research materials on the formula of air energy...... Whether I can become a seventh-level civilization depends on this time......"

In the darkness of space, a huge spaceship is sailing in a rapid curvature, heading into the distance. This is the scheduled meeting point of the Alliance. More than 300 Level 6 civilizations will gather here.

A civilization of different shapes and shapes left its lair and rushed there, and a huge starfleet was also heading towards that place, and in some corners of the universe, there were some strange things also advancing......

"It's a mesmerizing feeling, and now, the whole river system is under my command and control, following my orders and obeying my will." Standing in front of the transparent window of the spaceship, Aotian was thrilled as he watched the powerful beings that kept coming from all directions of the universe.

"Whether or not this encirclement and suppression can succeed is related to the future of all civilizations in our entire river system. Hereby I order, all non-level 6 civilizations are responsible for logistics, and all level 6 civilizations must use all their combat strength to face the enemy, because the enemy is stronger than all of us can imagine......"

"I announce that the name of the Guardian Alliance is now officially abolished, and from this moment on, we will have a common name, and that is the Andromeda Galactic Alliance! Our names are destined to reverberate throughout the universe, and now, let's take the first step and wipe out the Sweeper civilization! (To be continued......)
