"Well, I also agree to activate the planetary defense facility!" The general, who originally refuted, was speechless for a while, and reluctantly agreed.

They didn't know that the Empire had no intention of scanning this star system in detail, and that the First Fleet was originally planning to directly break through the Federation's main defense line and enter the Federation's hinterland.

But the command of this line of defense, fearing that he would be discovered, was the first to expose himself!

In the headquarters of the defensive line, the generals pressed the button on the console in front of them.

At this time, the planets in this star system began to change drastically.

The ground on the surface of the planets began to crack, and huge pillared buildings rose from beneath the ground.

After rising to a height of several thousand meters, the top of these columnar structures suddenly cracked, opening up a special equipment in the shape of an umbrella.

Immediately after that, blue light began to flicker on the umbrella-like devices, and after a few seconds, all the planets in the entire star system were covered with a blue shield.

At the same time, a huge fortress cannon nearly a kilometer high under the surface of these planets also rose from under the ground, and the thin layer of soil on the surface of the ground slid down the smooth shell of these fortress cannons and fell around.

With the deafening sound of gears turning, the fortress cannons aimed their muzzles at the starry sky where the Imperial fleet was located.

Think about it, as the headquarters of the entire defense line, it is impossible to have only two million warships as a protective force, and there must be a more powerful protective force hidden in the shadows.

At this time, the Imperial fleet was also stunned by these planets that had suddenly become planetary fortresses.

They didn't expect that this Federation would still hide so many defenses in this star system, originally they thought that this point was one of the weaknesses of the defense line, but the Federation was not so stupid.

"Scan these planets now! I want to know the detailed data of these planets! Eva commanded to her subordinates.

After living as a human for a long time, she has abandoned her mechanical body and instead lived in an artificial human body prepared for her.

Although she couldn't completely control the entire fleet, she found a sense of being human.

Therefore, if she wants to command the fleet now, she can only rely on roaring and letting her subordinates complete her orders.

"Yes!" The officer nodded, and began to make dots on the console.

After a while, several radar scanners with a diameter of hundreds of meters stretched out from inside the Imperial Flagship, the Bastion, and began to scan the surrounding planets thoroughly.

"The data has come out, there are a lot of military facilities hidden under these planets, but they didn't transform the entire planet into a fortress, just a common use of these planets." The officer looked up and reported to Eva.

"That's good, I thought this federation had turned these planets into fortresses!" Eva breathed a sigh of relief, although the planet was also armed, but this method of arming through the construction of military bases and batteries was obviously much weaker than the metalization of the entire planet.

Once the entire planet is metallized, it basically means that the planetary fortress must also be equipped with powerful destructive weapons, such as superweapons used to destroy planets or stars.

Since the other party simply built some turrets, Eva no longer worries, after all, no matter how strong the Imperial fleet is, it can't stop the attacks of those super weapons that can destroy stars.

"All the warships are ready to press, and I will wipe out all the fortress cannons on the surface of these planets!" Eva began to command the fleet to disperse and rush towards the planets.

These planets are thousands of meters high, and the barrel alone has reached the volume of nearly two thousand meters of fortress cannons, of course, it is not an ornament.

Not only does this mean that it is incredibly powerful, but it also means that it has an extremely long range, which means that they can attack one step ahead of the Imperial fleet.

Due to the slow speed of the physical shells, all of these Federated-built fortress cannons are beam weapons.

As they began to charge, the muzzles of the guns flashed blue.

Tens of seconds later, tens of thousands of pillars of light with a diameter of 100 meters shot from the surface of these planets towards the Imperial fleet.

Saying that it is a pillar of light is just a description of the effect of this weapon attack, these cannons are actually just particle beams, and the light pillars seen are just the light released by particle beams.

These beams crashed into the Imperial fleet, which was maneuvering to evade, in an instant.

In an instant, the flashes of light from thousands of explosions flickered in the Imperial fleet, and it was clear that an Imperial warship had already suffered an accident.

"Report battle damage!" Eva asked in a calm voice.

"Just now the enemy fortress artillery salvo we lost 1,200 Zeus-class battleships! More than 10,000 people died! The officer reported in a somewhat dull tone.

The sacrifice of more than 10,000 people! Ever since the Empire used clones to fight in battle, the Empire has never had so many natural people sacrificed!

"Eva, order the fleet to withdraw from the opponent's attack range!" Li Mingze, who was originally watching from the sidelines, suddenly spoke up.

"Yes!" Eva nodded and gave a command to all the ships, and the Imperial ship that was charging suddenly had its front engines fully open, stopping the battleship in the air, and then began to fall backwards at full speed.

Because of the gravitational engine, even if the retreat is reversed, it will not be too slow, so that the battleship's strongest armored front can be placed in front of it, preventing it from being taken away by the enemy's artillery with a single shot.

Although these fortress cannons are extremely powerful, they are still unable to penetrate the frontal armor of Imperial Zeus-class ships in one go.

The reason why more than a thousand battleships were sacrificed just now was because the opponent's attack was from the side to the Imperial warship.

When all the Imperial warships began to retreat, the Imperial flagship not only did not retreat, but rushed forward.

"Your Majesty, are you going to .....?" Eva looked at Li Mingze behind her.

"That's right, that's what you think." Li Mingze waved his hand lazily, and a sneer of disdain appeared on the corner of his mouth.

A few minutes later, the Empire's flagship Fortress rushed to the front of all the ships.

The bulky Fortress immediately attracted the attention of all the officers on the Union Line.

"All weapons aim at this ship and fire! This must be the other party's flagship! The generals of the Federation shouted in surprise.

Although I don't know what this flagship of the empire wants to do, since they dare to take the lead, then don't blame them for being ruthless!

A few minutes later, the cooled fortress guns aimed at the incoming Imperial flagship, the Bastion.

In an instant, the beams fired by the tens of thousands of fortress cannons all shot at the front of the fortress.

Unable to stop in time, the Fortress crashed headlong into the attack network composed of these beams! Instantly overwhelmed by countless rays of light!
