The convergence of civilizations has a great effect on science and technology, whether it takes place in peaceful or warlike conditions. Xiao Yu obtained the technology of the Predator civilization and the Pegasus civilization through the means of war, and realized the integration of science and technology, so the level of science and technology has made great progress, and the Pegasus civilization has formed a five-level civilization alliance through peaceful means, and the scientific and technological level of the five-level civilization alliance has also made great progress.

At least, this planetary battle star is much stronger than the one Xiao Yu saw in the Pegasus civilization capital galaxy. Xiao Yu was sure that if he tried to destroy the planetary shield of this planetary battle star by ramming it with a continent-level spaceship, he would definitely fail. Because the planetary shield of this planetary battle star has reached a certain level, the same kinetic energy can no longer destroy it.

Not only has the defense been improved, but the attack power of this half-finished planetary battlestar has also improved greatly. The super negative matter cannon built on the planet is the strongest weapon that can be built by a civilization below level 6 and a civilization level 5. Of course, space weapons are not in this category, because space weapons are the technological category of the sixth-level civilization.

At this moment, Xiao Yu truly saw the power of the strongest weapon of the fifth-level civilization. With the full speed of a huge base covering an area of several hundred square kilometers, a semi-circular instrument with a diameter of more than ten kilometers produced a series of inexplicable reactions inside, and after reaching a certain limit, a huge torrent of negative matter gushed out, like an unstoppable flood, leaving the planet in an instant, penetrating the planet's protective shield system, and coming into space.

In space, this torrent of negative matter is still unstoppable, and it easily completely annihilates a city-level spaceship in front of it. There was not even a bit of scum left, and the remaining power was still rolling forward, destroying a dozen county-level spaceships all the way, and also causing a little damage to one provincial-level spaceship.

Although Xiao Yu's city-level spaceship is not equipped with four maintenance covers, the city-level spaceship made with the latest technology still has quite strong defense. But in the face of the attack of the fifth-level civilization alliance's super negative matter cannon, a city-level spaceship was gone.

Xiao Yu did not care about these losses. This operation was originally a risk, and the overall success rate was less than 20 percent, and it was inevitable that there would be losses.

"This planetary battle star is a bit of a big threat to me......" Xiao Yu thought secretly. Do you want to rush over and kill it? Its planetary shield system has been greatly enhanced, but my ship's attack power has also increased, and the increase is even greater than that. Not...... It would take me about seven hours to break through the planet's shield. Pay the price of at least a million warships. ”

After thinking silently for a while, Xiao Yu still gave up this plan.

You want a quick fix. Then you have to maintain a certain amount of mobility. This means: Xiao Yu couldn't stay. If you stop, you may be encircled on a large scale. And destroying a planetary battle star has no meaning for Xiao Yu. You must know that in this star system, there are more than 100 planetary battle stars, and one is lost. What is it for the fifth-level civilization alliance?

Another five million diversion ships are launching their own attacks. With Xiao Yu's order, the five million spaceships immediately dispersed, and at the same time launched harassment operations against Liliang, the garrison of the Flower of Death Galaxy, in multiple locations. These harassment operations were very effective, Xiao Yu noticed. A large number of Liliang were attracted to the past, and correspondingly, the number of Liliang who came to block the progress of these 10 million ships will be reduced.

Xiao Yu is still moving fast. Asia, America, and Europe, the three most powerful continent-class spaceships, acted as the vanguard, and any spaceship that tried to block the advance of Xiao Yu's fleet would be repelled by these three continent-class spaceships, as well as the tens of millions of spaceships that followed. Xiao Yu even encountered a continent-level spaceship of the fifth-level Civilization Alliance and tried to block it, but in the face of the bombardment of nearly a hundred space weapons, this continent-level spaceship only lasted for a few minutes before it had to retreat helplessly.

That's the quality gap. The leadership of science and technology has brought about an increase in the strength of the battleship, Xiao Yu's fleet is like a group of hungry wolves rushing into the flock, and no enemy warship can last more than ten minutes under Xiao Yu's full attack!

However, there were too many ships in the Level 5 Civilization Alliance. As soon as the ships that stand in the way are destroyed, a new ship will be built in the rear. They were using their lives to slow down the progress of Xiao Yu's fleet.

I don't know how many spaceships are launching a fierce attack on Xiao Yu's fleet, and I don't know how many enemy warships Xiao Yu has destroyed since the start of the battle, Xiao Yu only knows that the front has always been covered with the shadows of enemy warships, killing them endlessly.

The more he advanced, the greater the resistance Xiao Yu encountered. The spaceships of the fifth-level civilization alliance seemed to be going crazy, like a large group of mosquitoes, constantly converging and launching a crazy attack on Xiao Yu's fleet. And Xiao Yu's fleet, in this endless sea of warships, rushed left and right, and marched forward bravely.

The battlefield here had clearly attracted the attention of the decision-makers of the Level 5 Civilization Alliance. Xiao Yu saw that there had once again been a large-scale military movement in Liliang, the garrison of the fifth-level civilization alliance, and nearly forty million spaceships were converging here. But military movements take time, and in a short period of time, they cannot all come together. All Xiao Yu has to do is to make a time difference and complete his goal before the large-scale fleet gathers. If you can't complete your objective, you should also withdraw before the enemy ships have finished assembling them.

The boundless flames of war have spread to an area of nearly 100 million kilometers in front and back, and this area has completely become a world of iron and blood. Xiao Yu's fleet has been moving forward and has not stopped. By the time the battle had been fought, Xiao Yu had advanced a distance of more than a billion kilometers, and there were still four billion kilometers left from the intended launch site of the stellar cannon.

In other words, as long as Xiao Yu advances another four billion kilometers, he can launch a stellar cannon and destroy this star. Once the star is destroyed, the violent energy from its explosion will sweep through all existences within trillions of kilometers, and it is certain that the huge warship group of the fifth-level civilization alliance, as well as the galaxy's defense system, will be swept away by the energy of this star's explosion like garbage.

"It seems that I underestimated the power of the elite fleet's assault operations before." Xiao Yu secretly thought in his heart, "If this situation develops, I have a great hope of completing the set strategic goals, if I can destroy this star, then I will win, and there will be basically no suspense." Kindness...... The success rate of this raid has been raised from 20 percent to 35 percent now. ”

Although the current battle situation has caused Xiao Yu heavy losses, in just a few hours, more than 100,000 warships have been destroyed, but Xiao Yu's harvest is also very large, Xiao Yu not only destroyed more than 300,000 enemy warships, but also let his fleet advance a distance of more than a billion kilometers.

In the midst of this fierce firefight, Xiao Yu's fleet advanced a full billion kilometers away. The resistance of the fifth-level civilization alliance became more resolute, and the number of spaceships became more and more numerous, but all of this could not stop Xiao Yu's determination to move forward. At this moment, Xiao Yu's grasp of destroying this star has reached 35%, and this probability is worth Xiao Yu's desperate efforts.

You must know that such a thing as destroying a star saves time and effort, and the stellar cannon is not a too high-tech thing, and it is not too difficult for Xiao Yu to manufacture it now. As soon as the stellar cannon is fired, the exploding star will replace Xiao Yu and destroy many enemy fortifications and warships, which is a very good deal.

Therefore, it is obvious that in interstellar warfare, the protection and attack of stars is the most critical. The fifth-level civilization alliance will definitely extract the most powerful liliang to protect the star, and Xiao Yu will also extract the most powerful liliang to attack the enemy's defense line in an attempt to destroy the star.

For this reason, Xiao Yu has made sufficient preparations, and for this goal, Xiao Yu did not hesitate to transfer the ten continent-class warships with the most powerful combat power here, and he would not care that he would lose hundreds of thousands or even millions of spaceships. As long as the stars can be destroyed, it will be worth the cost. Moreover, Xiao Yu also has a killer move from Zuihou.

This killer move is the ten percent of the spaceship combat power that Xiao Yu has hidden. Xiao Yu is looking forward to it, when Liliang, who was drawn from the fifth-level civilization alliance, has completely blocked himself, thinking that he is foolproof and absolutely impossible for Xiao Yu to break through the defense line, Xiao Yu will suddenly burst out with all his strength and break through the enemy's defense line in one fell swoop, what kind of expression will the decision-maker of the fifth-level civilization alliance be.

Now, it's time for Xiao Yu to use the killer weapon. At this time, nearly 40 million warships had participated in the battle to block Xiao Yu's advance, and the planetary battle star had been hiding on the edge of the battlefield, constantly attacking Xiao Yu's fleet. Xiao Yu's pace of progress has tended to stagnate. There is no way, there are too many ships in the fifth-level civilization alliance, enough to make up for the gap in quality.

"Then, it's time to use all your strength...... Xiao Yu gave an order, "It's time to release the hidden ten percent of the combat power......" (to be continued......)
