At this moment, in this small universe abandoned by a seventh-level civilization, Xiao Yu's research has entered a critical moment. The seventh-level civilization in the space direction is the most common seventh-level civilization, and space technology is the scientific and technological foundation of all seventh-level civilizations. Such a basic seventh-level technology is the best food for Xiao Yu's science and technology promotion.

"I don't need two thousand years anymore, with this small universe of seventh-level spatial direction civilization, I only need one thousand years to become a seventh-level civilization." Xiao Yu thought silently, "After becoming a seventh-level civilization, I will explore the entire Andromeda Galaxy, if there is nothing I want in the Andromeda Galaxy, then I will set off for the rest of the river system......"

"Huh? Why is there so much space fluctuation all of a sudden? At this time, through the space monitoring device that was running all the time, Xiao Yu noticed something unusual.

Space monitoring technology is the most powerful detection technology of the seventh-level civilization, and according to the depth of progress in this technology, the seventh-level civilization can monitor all spatial fluctuations above a certain intensity within the range of tens of thousands to hundreds of thousands of light-years through this technology. With Xiao Yu's current technology, Xiao Yu can probably monitor all spatial fluctuations within a radius of 100,000 light years with a speed of more than 70 times.

It is normal for there to be spatial fluctuations in a river system, because curvature navigation is all too common in slightly more advanced civilizations. In the past few hundred years, Xiao Yu has monitored hundreds of millions of spatial fluctuations with a speed of more than 70 times the speed of light every second on average. Recently, however, that number has grown dramatically. So far. This number has expanded hundreds of times, approaching the level of 100 billion. This finally caught Xiao Yu's attention.

"The sudden increase in spatial fluctuations means a lot of things, and it has a lot of possibilities. But whatever the possibility, whether it is military or civilian, it must be a large-scale mobilization. And now...... These wave sources come from different places in the Andromeda Galaxy, and they are distributed in a dotted shape over the whole, and nearly 100 billion wave sources are probably divided into more than 200 points. The distribution of these points is irregular. Let me monitor the direction of these wave sources again......"

"The direction of these points is chaotic, but if you look at it from a macro perspective, they have an approximate meeting point. The meeting point is here, which is only a few hundred light-years away from me...... Not. I see, I see. ”

Things have come to this point, how can Xiao Yu still not understand what happened.

"It seems. There is a powerful person who has organized all the advanced civilizations of the Andromeda Galaxy, ready to deal with me...... More than 200 sixth-level scientific and technological civilizations have joined forces...... No, there must be more than that. My current detection accuracy is not high enough. Only large-scale curvature maneuvers can be detected by me. Then concentrate here to roughly analyze how many warships are involved, and I have no way of detecting the curvature of single civilizations such as the Taihao civilization and the alien beast civilization. More than 200 sixth-level scientific and technological civilizations have been dispatched, and I believe that there will definitely be a considerable number of alien beasts and Taihao civilizations involved......"

"What a powerful force this is......" Xiao Yu sighed silently, "Although the quality of civilization in the Andromeda Galaxy is not as good as that of the Milky Way, the quantity is much higher. And now, all civilizations have united against me. Your purpose is nothing more than to gain access to my technology, but I want you to know. If you want to get my technology, sometimes you can't achieve it at any cost......"

Xiao Yu had already grasped the enemy's movements in advance. This is the advantage of seventh-level civilization technology.

"Then let me estimate your combat power...... Roughly speaking, there will be about 50 billion warships at the level of sixth-level civilization, that is, the speed of curvature is more than 100 times the speed of light, which is enough to pose a certain threat to me. Since there are so many sixth-level scientific and technological civilizations, the number of Taihao civilizations must not be less. Taihao and the alien beasts add up to a hundred. A Taihao civilization or an alien beast has at least the combat power equivalent to one of my stellar-class warships, then this is a hundred stellar-class warships...... Well, in general, the enemy's combat power is very strong, and there is indeed hope of victory in the face of a quasi-seventh-level civilization that has not yet fully stepped into the seventh-level civilization category. ”

"Is the allure of the scientific and technological data of the seventh-level civilization really so powerful?" Xiao Yu sighed.

Xiao Yu knew that the scientific and technological information of the seventh-level civilization could not be passed on. If you pass on these scientific and technological materials to the rest of the civilizations, then you will be punished by the defenders of the underworld, and it is not good to even erase yourself. Although it is speculated that the Rebel Alliance is secretly helping him, there is no need for Xiao Yu to anger the defenders now. But don't spread the word that this restriction is for yourself, and if you spread it, you will only be punished for it. From another point of view, if Xiao Yu is a sixth-level civilization, if Xiao Yu has a chance to rob the technology of a seventh-level civilization, Xiao Yu will also be happy to do it. Anyway, it's not yourself who will be punished in the end, so why not?

What's more, only civilizations that have successfully carried out superparticle acceleration experiments, have initial contact with the air energy formula, and have contact experience with the Guardians will know the restriction that the scientific and technological data of the seventh-level civilization cannot be disseminated. A sixth-level civilization wouldn't know this at all.

"It seems that a big war is inevitable. However, since I am a sweeper, it is also the right thing to do to clean up the rest of the civilizations, not to mention that they are taking the initiative to provoke me. Xiao Yu thought secretly and began to make preparations for the war.

Xiao Yu didn't think about escaping at all. If you run away, why run away? A quasi-seventh-level civilization, or a seventh-level civilization with a huge advantage like oneself, needs to escape when faced with a bunch of sixth-level civilizations?

There is another reason, that is, Xiao Yu has been provoked. In a military operation of such a magnitude that ripples over the entire river system, there must be a leader and organizer. And those who know their own situation and are qualified to take on the position of leader and organizer will only come from the sixth-level civilizations that escaped from the small universe before. You know, it was because of the bitter pleading of the flame civilization and the mercy of his subordinates that these civilizations were able to continue, and now, these civilizations have taken revenge and organized forces to deal with themselves in turn? Trying to rob your own technology?

"In this universe, I am the only one who robs others, and where do others rob me. Since you don't know what to do, then I can only wipe you all out and do my duty as a cleaner civilization......"

Xiao Yu can now operate up to 500 million warships at the same time. In terms of quantity, Xiao Yu is at an absolute disadvantage. However, Xiao Yu is on the defensive, occupies a favorable geographical position, and has an advantage in science and technology, Xiao Yu is not worried that he will fail at all.

In the final analysis, Xiao Yu didn't take these enemies in his eyes at all.

Time is still slipping away quietly, and Xiao Yu is still conducting his scientific research as usual, as if he is ignorant of the turbulent waves of the outside world. This situation was broken in the middle of an ordinary day.

Xiao Yu sent several small warships to the outside of the small universe and witnessed the whole scene here.

The surrounding space is constantly fluctuating like water ripples, so that the stars in the sky become shadowy and unrealistic. As these water streaks continued to flash, one after another spaceships appeared here.

Such a scenario takes place in a very large range. In just a few minutes, tens of millions of warships appeared here. They seem to belong to the same group, and after appearing here, they are neatly arranged together according to some pattern. Outside of this group was another group, and that was in another direction, and there were also ships constantly appearing there, and at the same time, in the third direction, in the fourth direction......

A total of more than 200 warship groups were gathered here, and the total number of warships slightly exceeded Xiao Yu's previous expectations, about 60 billion ships. In addition to these 60 billion warships, there are more than 100 huge figures that disappear from time to time, constantly rising and falling in the void......

Behind these more than 60 billion warships, there are even more ship groups that are being assembled. The technological level of the spaceships here is uneven, there are five levels of civilization, some are four levels of civilization, and along with them, tens of thousands of stars and countless planets, a total of more than 300 billion ships of all kinds shuttle back and forth here. Obviously, it was the rear position of the Alliance of Sixth-Level Civilizations, and all the low-level civilizations there were responsible for logistics.

This is the world of battleships. Endless battleships spread throughout the space, front, back, left, right, and up, all spreading to the end of the line of sight. These ships are of different shapes and technologies, they are large or small, and the outer layer of the battleship is shimmering with a pale blue or dark green shield......

At least 95% of the civilizations in the entire Andromeda Galaxy are concentrated here, ready to participate in this war that is destined to bring about upheaval in the entire Andromeda Galaxy.

Xiao Yu sighed faintly: "My subordinates spared you mercifully, but I didn't expect you to gather so many civilizations to deal with me...... Since you're here, let's stay......"

"You hateful outsider, invader. You didn't belong to the Andromeda galaxy, but you came here, encroaching on our living space and killing our civilization, so we have to protect ourselves, and we have to unite to drive you out of ......" (to be continued......

PS: I saw that some book friends questioned that the technology of the seventh-level civilization could not be transmitted, so the sixth-level civilization alliance should not come to trouble Xiao Yu, so I deliberately explained it in the chapter.
