Xiao Yu is methodically upgrading the battleship. It is too difficult for a sixth-level civilization spaceship to be transformed into a seventh-level civilization spaceship, and it is very uncost-effective to do so, so Xiao Yu simply dismantled a large number of reserve warships, recycled the available materials, and rebuilt them into a new type of spaceship through a series of refining, processing and other measures.

At this point in the battle, Xiao Yu's warships had only been destroyed, probably less than 500 million. Although this number is huge, it is insignificant compared to Xiao Yu's reserve of tens of billions of warships. Many warships were stored in the small universe, and they were directly dismantled without experiencing the baptism of war at all. This scene made Xiao Yu sigh.

The manufacturing technology of the new provincial warship has matured, and Xiao Yu began the construction of the national spacecraft. The ultimate thing Xiao Yu can do now is to build a national-level spaceship the size of a city-level spaceship at this stage, but the internal space is enough to put down a stellar-class battleship. Compared to provincial ships, it has more defense, mobility, and attack power.

In the defense of Galaxy IV, the three newly built national ships participated in the battle. Under the cover of many spaceships, these three national-level spaceships quietly killed two sixth-level alien beasts, and only after fully verifying their performance did they withdraw from the battle. And in order to continue to stimulate the Andromeda Galaxy Alliance, Xiao Yu also gave up the No. 4 galaxy in this battle. The flame civilization became more and more pessimistic about this, and the Andromeda Galactic Alliance once again launched a grand celebration.

Almost all members of the Andromeda Galactic Alliance believe that victory is at hand.

Xiao Yu found that in his heart. A strange, abnormal thought is inexorably growing, such as "If only the Andromeda Galactic Alliance had been a little stronger". Or "why is the enemy so weak" and so on. Now Xiao Yu urgently needs a stronger enemy to help him test the performance of the spaceship.

Xiao Yu likes to fight now, but he doesn't dare to use all his strength. Because Xiao Yu knew that as long as he used all his strength, the entire Fairy Galaxy Alliance would immediately collapse, and the members of the alliance would scatter as quickly as possible and escape from this small universe. And now. The game hasn't been played enough, and Xiao Yu doesn't want to lose this enemy.

So now Xiao Yu has begun to challenge some perverted gameplay. Up to now, Xiao Yu had built a planetary-class battleship of the seventh-level civilization category. A planetary-class battleship is only the size of a national spaceship, but the space inside is large enough to fit an Earth. Its combat power was very strong, and in Xiao Yu's estimation, a planetary-class battleship was enough to destroy a sixth-level civilization.

Xiao Yu tried to surround the three sixth-level alien beasts and a single Taihao civilization. And then without attracting the attention of the rest of the large forces. Cut these four guys who can be called powerful in the sixth-level civilization level into the small universe together. The scope of the small universe is not large, and in order to maintain its stability, Xiao Yu also needs to continuously provide energy for this small universe.

After these four monolithic civilizations were cut into the small universe, Xiao Yu also put one of his newly built planetary-class battleships into it. That's right, all Xiao Yu has to do is use this planetary-level battleship to face the four enemies in front of him.

This small universe is the Colosseum that Xiao Yu specially built for himself.

"What's going on?" The three alien beasts that were cut into the small universe without defense, as well as a Taihao civilization, were all a little confused. After all, the league has been on a high trajectory all this time. conquered three star systems in a row, compressing Xiao Yu's station into two galaxies. Including them. Almost everyone believes that victory is no longer far off.

"I'm a sweeper, civilization. Now I'm going to give you a chance, as long as you can destroy the national spaceship in front of you, I can spare your lives...... If you can't destroy this national warship, consider this your graveyard. Just when they were confused, Xiao Yu's signal came out.

A sixth-level alien beast turned over in disbelief, looking at the spaceship in front of him with an idiot-like look, but in fact it was a planetary-level spaceship, and said with disdain: "Sweeper civilization? Let us live? Hahahaha, Sweeper Civilization, I tell you, give up resistance immediately, hand over all your scientific and technological materials, and I can advise the leader of the alliance to give you a chance to be a slave. ”

"Listen, this is the last chance, if you resist any longer, when we break through your station, everyone in your civilization will die!" Another sixth-level beast was also echoing.

Only the techno-tech Taihao civilization didn't say a word. It wasn't a beast civilization, and it had sensed that something was wrong with the atmosphere in front of it. Especially after it tried to leave this small universe, but failed for no reason, a sense of foreboding was born in its heart.

"A bunch of idiots. In that case, I'll give you a little punishment first. Xiao Yu said lightly, and activated the weapons equipped on this planetary-level spaceship. Immediately, a bright white, thick white line that seemed to be a ray weapon appeared on its bow part, and this white light traveled faster than the speed of light, and only in an instant, it reached the body of this sixth-level alien beast.

With the earth-shattering howl of this sixth-level beast, a terrifying blood hole appeared on its body. This white light only lasted for a moment, and after a while, Xiao Yu stopped attacking and continued to send a message: "If you want to live, destroy this spaceship, otherwise, you will die here." ”

The techno-Taihao spaceship moved almost instantly, it was moving desperately, trying to leave this small universe, and at the same time desperately sending messages with all the communication methods it mastered: "Run, run!" The sweeper civilization has been teasing us, has been teasing us! ”

Xiao Yu didn't pay attention to its movements at all. Xiao Yu is sure that as long as he doesn't want to, all the information can't be sent out of this small universe.

After trying for half a day to no avail, the tech-like Taihao spaceship sent out a message full of madness: "Let's get on it together!" If you want to survive today, kill this ship! ”

Three sixth-level beasts, a spaceship of the Taihao civilization of science and technology, rushed towards this planetary-level spaceship......

An hour later.

Looking at the corpses of alien beasts in the small universe, as well as the fragments of battleships and flesh and blood of alien beasts everywhere, Xiao Yu's phantom pouted boringly: "It's really boring." ”

The Andromeda Constellation Alliance has really become Xiao Yu's sparring partner. Under the run-in of the Andromeda Alliance, the national-level spaceship was born, the continent-class spaceship was born, and the planetary-class spaceship was also born.

Xiao Yu began to try a new way to play again. Normally, Xiao Yu would only use three to five percent of the performance of a new spaceship, and then mix these ships into a large army to participate in the battle. In the fierce battle, these spaceships will encounter all kinds of unexpected situations, their own design shortcomings or structural defects will be exposed little by little, and after these flaws are exposed, Xiao Yu will leave to find solutions, re-optimize these self-built spaceships, and then put them on the battlefield again to be tested.

While constantly improving these spaceships, Xiao Yu is also researching another extremely powerful weapon. Similarly, Xiao Yu still intends to let the Andromeda Galaxy Alliance try this weapon first......

The Andromeda Galactic Alliance has become a qualified and slightly tragic carving knife, sacrificing its sharpness to help Xiao Yu polish these temporarily immature creations. Xiao Yu was sure that if it weren't for such a qualified sparring partner, the process of building his own spaceship would not have been so smooth.

But in Aotian's view, this is clearly not the case. In fact, at this moment, Aotian is surrounded by glory and praise. When Galaxy 2 was also conquered, Aotian's prestige reached its peak.

"Ladies and gentlemen, our alliance has made great sacrifices and has come to where it is today. Now, the final victory is only one step away, and if we take this star system down again, we will reap the ultimate results...... We will become a seventh-level civilization and have the qualifications to march to a higher level of the cosmic stage. ”

"With everyone's help and cooperation, I have been able to lead our alliance to where it is today. Today, glory not only belongs to me alone, glory belongs to everyone! To all of you! Aotian was giving an impassioned speech, and the audience was fascinated.

"I order, tomorrow begins the final battle against the Sweeper civilization! This battle must wipe out all the Sweeper civilizations and rob us of all their technology and resources! ”

"Long live the Alliance! Long live the Union! Countless cheers resounded throughout the lobby.

And at this moment, Xiao Yu was looking at one of his newly built warships. The ship wasn't huge, but it had enough space inside to fit the entire Earth-Moon system.

Its speed reached an astonishing 1,500 times the speed of light, it could destroy a star with a single blow, or it could withstand the full force of a sixth-level beast for several hours without any damage.

This is the most powerful war weapon Xiao Yu has ever made. Any weapon equipped on it was enough to make even a sixth-level civilization tremble.

This is a stellar-class battleship created by seventh-level civilization technology.

"My purpose has been achieved, and there is no need for the Andromeda Alliance to exist......" (To be continued......)
