Surrounded by up to 45 million spaceships, and after Xiao Yu's more than 9 million spaceships had lost the possibility of escaping with their own Liliang, the strongest war weapon that a fifth-level civilization could build, the planetary battle star, the Earth, set off.

The planetary battle star built by Xiao Yu is very different from the planetary battle star built by the fifth-level civilization alliance. This difference is not only manifested in the fact that the Earth can sail at curvature, while the planetary battle stars built by the Alliance of Civilizations at the fifth level cannot sail at curvature.

In addition to this, there are many differences, the most obvious of which is that Earth has greater maneuverability.

Due to the limitations of the planet's material, it is not able to accelerate and decelerate too quickly. If you accelerate or slow down too quickly, it can cause extremely serious damage to the planet itself, triggering strong geological activities such as earthquakes and volcanoes, and even being torn apart by inertia. In order to cope with this, Xiao Yu has done a lot of work.

Xiao Yu used extremely advanced scientific and technological means to calculate the key tens of thousands of stress points of the planet when accelerating and decelerating, and then carried out large-scale construction of these key stress points nearly 4,000 kilometers below the surface of the planet, and used hundreds of billions and trillions of tons of special materials to strengthen the strata and rocks there, and constructed a complete stress distribution system, which can evenly disperse the liliang generated by the planet's acceleration and deceleration to the entire planet. This gives the planet maximum mobility.

This kind of technology, Xiao Yu can be sure, among the fifth-level civilizations, only he has it. With this jishu, the planetary battlestar can accelerate and decelerate nearly two hundred meters per second during regular navigation. This mobility. Although the spaceship is still much worse than that, this is a planet after all, and the two are not the same. With this data, it is amazing enough. This means that it takes less than 14 hours for this planetary battle star to accelerate from a standstill to 10,000 kilometers per second.

In this regard, the Earth has completely distanced itself from the half-finished planetary battle stars created by the fifth-level civilization alliance.

"Earth, let's start fighting...... Let the Level 5 Civilization Alliance see what is the strongest weapon within the scope of Level 5 civilization! Xiao Yu gave this order with confidence.

Under Xiao Yu's manipulation, the Earth slowly left the station of the Homeland spacecraft. From this moment on. The defense of the Homeland spacecraft will be in charge of the Biological Corps. The Biological Corps has about two million warships, which is enough to withstand the attack of less than four million warships of the fifth-level civilization alliance. Of course, if the fifth-level civilization alliance launched a large-scale attack on the Homeland spaceship, sending tens of millions of spaceships. Xiao Yu will manipulate the Homeland spaceship into the curvature voyage and start to escape. Anyway, the speed of the Homeland spaceship is faster than the speed of the ship made by the Level 5 Civilization Alliance. Don't worry about being caught up by them.

Because there have been many ship losses in the past. Xiao Yu has already saved some of his computing power, and this part of his computing power has been put by Xiao Yu on the reserve spaceship on the planetary battle star, and a full million spaceships have left the planet battle star and come to space, acting as the escort of the planet battle star.

As soon as the planetary battle star was dispatched, the fifth-level civilization alliance immediately reacted. There were many warships that were originally rushing towards the Asia's spaceship cluster, preparing to encircle and suppress Xiao Yu's more than 9.5 million spaceships. Swiftly changed his orbit and rushed towards the approaching planetary battlestars. Planetary Battlestars are already the most mobile in their class, but compared to battleships. It's still a lot worse. This also means that it is impossible for Planetary Battlestars to escape the harassment of these warships.

If you can't hide, then don't hide. In fact, Xiao Yu had no intention of hiding at all. Because Xiao Yu knew that these warships could not pose a threat to his Earth at all.

The two parties finally came together. A city-level spaceship of the Level 5 Civilization Alliance preemptively launched an attack on the Earth. A large number of negative matter bombs, gravity bombs, light weapons, negative matter weapons, etc., bombarded like a tide. However, these attacks did not have even the slightest impact on the planetary battle star. The outermost layer of the thought maintenance cover did not even show a ripple at all. The Earth completely ignored the attack of the city-level ship.

The 60,000 large-scale energy bases, with an average area of more than 20 square kilometers, provide an unspeakable energy supply for the four maintenance covers. And because they are built on planets, these energy bases do not have any concerns about insufficient supply of raw materials. Moreover, even if the four maintenance shields are breached, under the four maintenance covers, there are still conventional shields supported by nearly 80,000 energy bases, which are protecting the planetary battle stars.

This fifth-level civilization alliance city-level spaceship was violently attacking the planetary battle star, but in the next moment, it turned into two halves out of thin air, and the next moment, it exploded violently, turning into a fireball.

One of the nearly five hundred space weapons equipped on the planetary battlestar unleashed its own attack. Because they are built according to planets and have an almost unlimited energy supply, any of these space weapons are more powerful than Xiao Yu's most powerful warship, the space weapons on the spaceship Asia. A space weapon of this intensity, not to mention a city-level spaceship, even a provincial-level spaceship can be directly destroyed.

The destruction of this city-level spaceship opened the curtain on the first time that the Earth participated in the battle. After the destruction of this spaceship, the first large forces of the fifth-level civilization alliance arrived, and nearly a million ships came to the planetary battle star, and there was even a continent-level ship. A fleet of one million planetary battlestars quickly met the ship and engaged in battle.

The task of these escort fleets is not to destroy these ships at all, although they can do it all. But Xiao Yu didn't do this, Xiao Yu chose another faster and more convenient way.

Because of the participation of one million escort ships, the first batch of attack fleets sent by the Fifth Civilization Alliance suffered from very serious harassment. So, the planetary battle star came into power.

On the planetary battle star, Xiao Yu has built a total of nearly 500 space weapons, more than 300 super negative matter cannons, and a variety of ground-based and space-based light weapons, bombs, and missile weapon launch fortresses. This planet has been completely transformed into a war fortress by Xiao Yu.

Through a simple description, you can understand how profound Xiao Yu's transformation of this planet is. This planet was originally a rocky planet, with a variety of terrains on it, such as mountains, basins, canyons, etc., but after Xiao Yu's transformation, there are no natural bumps on the surface of this planet. All the mountains were flattened by Xiao Yu, and all the canyons, basins, and caves were filled by Xiao Yu. In its place, there are endless artificialities, all kinds of bases that shimmer with metallic luster. Even, apart from the mining base, there is no bare earth on the surface of this planet.

You know, the surface area of this planet is even larger than that of the earth, and the surface of such a planet is covered with artificial buildings, what a huge construction project!

These artificial, base-based, all-in-one planet-related creatures are all war-related. It is conceivable that such a planet can exert such a powerful combat power!

Now, the planetary battle star has been fully activated. In the face of this first batch of a million enemy warships, space weapons began to be launched, super negative matter cannons began to be launched, and all kinds of conventional weapons, batteries, and fortresses began to attack......

Countless thin black lines rose from the surface of the earth and rushed into the sky at a speed invisible to the naked eye, countless invisible torrents of negative matter rushed from the earth to the sky like a thin flood, countless missile weapons swayed their long tail flames, rushing into the sky like fireworks, and countless visible and invisible rays were launched from various bases and fortresses, and also killed the sky......

Under this fierce offensive, with the cooperation of a million escort fleets, only half an hour later, the first batch of one million enemy spaceships to attack had already suffered more than seventy percent of the battle losses, and even the enemy continent-class spacecraft exploded under the siege of hundreds of space cracks, thousands of super negative matter cannons, and tens of thousands of warships.

It was the first continental-class ship to be destroyed since the war began.

"Good!" Xiao Yu couldn't help but secretly applaud. The continent-class spaceship has a special significance, and the loss of a continent-class spaceship is very serious for any civilization below level six.

Xiao Yu knew the plans of the fifth-level civilization alliance. The fifth-level civilization alliance should be Jihua to use a million warships in advance to slightly delay the progress of the planetary battlestars and buy time for the arrival of the follow-up fleet. But things have developed so far, and they have completely exceeded their expectations.

Who would have thought that a million warships, a full million warships, would be lost by more than seventy percent in just half an hour, and even the continent-class spaceship would be killed by the other side?

Who would have thought that this planetary battle star would be so strong?

More ships are starting to converge here, and a tight line of defense has emerged in front of the planetary battlestars. This line of defense consists of at least 10 million ships, and it is constantly increasing. But Xiao Yu did not hesitate in the slightest. The planetary battlestar didn't stop for a moment, and directly collided with it. (To be continued......)
